===============================CHAIRMAN'S MESSAGE===============================

DEAR FELLOW SHAREHOLDERS:

During the last decade, investors have become used to seeing stock market
returns averaging 15% or so each year. In the past three years, the stock market
has treated us to a record run, producing annual returns in excess of 20%.

      After such a long and remarkable performance, many began this year
wondering what the market would do for an encore in 1998. The answer so far has
been more of the same, even with the recent increase in volatility caused by
tremors from Asia. This achievement continues to bolster many investors'
convictions that the market will produce these results forever, or, in the worst
case, that market declines will always be short-lived. While the economy remains
solid and the environment favorable, history and reason tell us it's a highly
unlikely scenario.

      This doesn't mean we know what the market will do next, or that it's
riding for a fall. But after such a run, even in this "new era" of strong
economic growth with low inflation, we believe it would be wise for investors to
set more realistic expectations. As we've said before, markets do indeed move in
two directions. Over the long term, the market's historical results have been
more in the 10% per year range, which is still a solid result, considering it
has been produced despite wars, depressions and other social upheavals along the
way.

- --------------------------------------------------------------------------------

Officer, flush right, next to third paragraph.]
- --------------------------------------------------------------------------------

      In addition to adjusting, or at least re-examining, expectations, now
could also be a good time to review with your investment professional how your
assets are diversified, perhaps with an eye toward a more conservative approach.
Stocks, especially with their outsized gains of the last three years, might have
grown to represent a larger piece of your portfolio than you had originally
intended, given your objectives, time horizon and risk level.

      At John Hancock Funds, our goal is to help you reach your financial
objectives and maintain wealth. One way we can do that is by helping you keep
your feet on the ground as you pursue your dreams.

Sincerely,


/S/ Edward J. Boudreau, Jr.

                                  John Hancock
                              Intermediate Maturity
                                Government Fund

                   U.S. bond market rallies through year end,
                            then stalls in early '98

Recently, Barry Evans assumed leadership of the Fund's management team. Mr.
Evans, a senior vice president, is head of the government and municipal
fixed-income departments at John Hancock Funds.

The U.S. bond market started the past year off with a roar and ended it with a
yawn. Bonds began to rally last summer and kept up their pace through December,
thanks to lower-than-expected inflation and the expectation that Asia's
financial crisis would slow U.S. economic growth. By January, with the U.S.
economy showing no signs of weakening, the rally ended. Yields on the 10-year
Treasury, which had tumbled from 6.66% on May 31, 1997, to 5.36% on January 12,
1998, settled in between 5.4% and 5.8% for the next five months.

   Initially, when interest rates were falling, Treasuries posted strong
returns. Long-term Treasuries did especially well as inflation fears waned. But
prices on mortgage bonds rose at a slower rate, as interest rates fell and
prepayment concerns grew. Prepayments occur when homeowners pay off their
existing mortgage loans before their due dates to refinance at lower rates.

           John Hancock Funds - Intermediate Maturity Government Fund

"The Fund also benefited from adjusting its asset allocation..."

- --------------------------------------------------------------------------------
["Pie chart with the heading  "Portfolio  Diversification"  at the top left hand
column.  The chart is  divided  into 3  sections.  Going from top left to right;
Short-Term  Investments 4%; U.S.  Treasuries 46%; U.S.  Government Agencies 50%.
Footnote below states "As a percentage of net assets on May 31, 1998."]
- --------------------------------------------------------------------------------

When prepayments rise, mortgage bond investors lose the opportunity for higher
yields and have to reinvest at lower rates. As interest rates started leveling
off in 1998, however, bonds like mortgages that had a yield advantage over
Treasuries edged ahead.

   In this changing environment, John Hancock Intermediate Maturity Government
Fund managed to come out ahead. The Fund's Class A and Class B shares had total
returns of 9.56% and 8.74%, respectively, at net asset value, for the year ended
May 31, 1998. Keep in mind that your net asset value return will be different
from this performance if you were not invested in the Fund for the entire period
and did not reinvest all distributions. By comparison, the average
intermediate-term government fund returned 9.32%, according to Lipper Analytical
Services, Inc.(1) During the same period, the Lehman Brothers Intermediate
Government Bond Index returned 8.58%. For longer-term performance information,
please see pages six and seven.

   Some of the Fund's gains came from its slightly long duration of 4.3 years.
Duration measures how sensitive a bond's price is to interest-rate changes. The
longer a bond's duration, the more its price will rise as interest rates fall --
or fall as rates rise. This helped the Fund initially. Although interest rates
stabilized beginning in January, we kept duration unchanged. Our expectation was
that any rise in interest rates would be minimal, given how high real (or
after-inflation) yields were and the fact that new Treasury issuance was
declining.

Staying nimble

The Fund also benefited from adjusting its asset allocation as market conditions
shifted. During the fall, the Fund maintained a lighter-than-average stake in
mortgage bonds and a large investment in interest-sensitive U.S. Treasuries.
This worked well when interest rates were declining and bond prices were rising.
Then, in early 1998, we boosted our mortgage stake to 37%, up from 25% at the
end of November. A wave of prepayment fears had weakened prices, making
traditional mortgage bonds more attractive. Our focus was on 30-year bonds
issued by the Government National Mortgage Association (GNMAs) with 7% coupons
(or stated interest rates) and 15-year bonds issued by Federal National Mortgage
Association (FNMAs) with 6.5% coupons. We targeted bonds with lower coupons than
those on mortgages that were being prepaid, but higher coupons than those on
newly issued mortgages.

   During the months after we bought them, the Fund benefited as prepayment
fears eased and prices on mortgage bonds regained some of the ground they had
lost relative to Treasuries. With hindsight, the Fund would have benefited even
more from a higher mortgage stake. However, we were cautious about further
increasing our investment in this area because we were concerned that if the
economy began to slow and

- --------------------------------------------------------------------------------

interest rates began to fall, prepayments would accelerate even more. To boost
our mortgage stake, we trimmed Treasuries to 46% of total net assets, down from
54% at the end of November. We also pared back our adjustable rate mortgages
(ARMs), which were experiencing faster prepayments than expected as homeowners
raced to lock in lower rates on fixed-rate mortgages.

   A 13% stake in other types of U.S. government agency bonds also helped the
Fund later in the period. Once the rally was over, these bonds -- mostly
short-term bonds that could be "called" or paid off in less than two years --
offered a slight yield advantage over Treasuries.

Expecting a slowdown

Our expectation is that the economy will eventually grow at a more moderate
pace, causing interest rates to fall. For starters, it's unlikely that consumer
spending will continue at the brisk rate we saw in the first quarter of 1998
when unseasonably warm winter weather boosted sales. A gigantic inventory
build-up in the first quarter may also lead to decreased industrial production
going forward. Finally, as Asia's problems play out, we expect the U.S. trade
deficit to widen and lower gross domestic production. We'll be keeping a close
eye on all these areas for signs of a slowdown. We'll also be watching corporate
earnings to see whether they're growing at a slower rate than before.

   Given this outlook, we're mildly optimistic about the bond market. There are
two positives already at work. Real rates -- interest rates after inflation --
are historically high. Plus, as the budget deficit has narrowed, the government
has had less need to issue U.S. Treasury bonds. If supply continues to shrink
and demand continues to remain strong, bond prices will move up. Once the
economy shows signs of more moderate growth, we believe yields could break
through the bottom of the range they've been in since January. When this will
happen is hard to say because the effect of the Asian credit and currency crisis
on the U.S. economy is still such an unknown. While we're waiting for the
economy to slow, we'll stick with our current duration and possibly add to our
stake in bonds issued by U.S. government agencies.

"Our expectation is that the economy will eventually grow at a more moderate
pace..."

                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Intermediate Maturity Government Fund. Total
return measures the change in value of an investment from the beginning to the
end of a period, assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 3%.

Class B performance reflects a maximum contingent deferred sales charge (maximum
3% and declining to 0% over four years).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

The charts on the right show how much a $10,000 investment in the John Hancock
Intermediate Maturity Government Fund would be worth, assuming all distributions
were reinvested for the period indicated. For comparison, we've shown the same
$10,000 investment in the Lipper Intermediate U.S. Government Index and the
Lehman Brothers Government Bond Index. The Lipper Intermediate U.S. Government
Index is an equally weighted unmanaged index that measures the performance of
funds with at least 65% of their assets in securities issued or guaranteed by
the U.S. government, its agencies or instrumentalities with dollar-weighted
average maturities of five to ten years. The Lehman Brothers Government Bond
Index is an unmanaged index that measures the performance of U.S.Treasury bonds
and U.S. government agency bonds. Past performance is not indicative of future
results.

           John Hancock Funds - Intermediate Maturity Government Fund


NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is a diversified, open-end management
investment company, registered under the Investment Company Act of 1940. The
Trust consists of three series: John Hancock Intermediate Maturity Government
Fund (the "Fund"), John Hancock Government Income Fund and John Hancock High
Yield Bond Fund. The other two series of the Trust are reported in separate
financial statements. The investment objective of the Fund is to achieve a high
level of current income consistent with preservation of capital and maintenance
of liquidity.

   The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A and Class B. The shares of each class represent
an interest in the same portfolio of investments of the Fund and have equal
rights to voting, redemption, dividends and liquidation, except that certain
expenses, subject to the approval of the Trustees, may be applied differently to
each class of shares in accordance with current regulations of the Securities
and Exchange Commission. Shareholders of a class which bears distribution and
service expenses under the terms of a distribution plan have exclusive voting
rights to that distribution plan.

   Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement transaction. Aggregate
cash balances are invested in one or more repurchase agreements, whose
underlying securities are obligations of the U.S. government and/or its
agencies. The Fund's custodian bank receives delivery of the underlying
securities for the joint account on the Fund's behalf. The Adviser is
responsible for ensuring that the agreement is fully collateralized at all
times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code.

FEDERAL INCOME TAX The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gains on
investments, to its shareholders. Therefore, no federal income or excise tax
provision is required. For federal income tax purposes, the Fund has $17,040,448
of a capital loss carryforward available, to the extent provided by regulations,
to offset future net realized capital gains. To the extent that such
carryforward is used by the Fund, no capital gain distributions will be made.
The carryforward expires as follows: May 31, 1999 -- $1,018,204, May 31, 2000 --
$23,234, May 31, 2001 -- $11,348,721, May 31, 2002 -- $427,159, May 31, 2003 --
$1,950,205, May 31, 2004 -- $1,741,681 and May 31, 2005 -- $531,244. The Fund's
tax year end is May 31. Expired capital loss carryforwards are reclassified to
capital paid-in, in the year of expiration.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

   The Fund records all distributions to shareholders from net investment income
and realized gains on the ex-dividend date. Such distributions are determined in
conformity with income tax regulations, which may differ from generally accepted
accounting principles. Dividends paid by the Fund, if any, with respect to each
class of shares will be calculated in the same manner, at the same time and will
be in the same amount, except for the effect of expenses that may be applied
differently to each class.

EXPENSES The majority of the expenses of the Trust were directly identifiable to
an individual fund. Expenses which were not readily identifiable to a specific
fund were allocated in such a manner as deemed


                                       14

           John Hancock Funds - Intermediate Maturity Government Fund


equitable, taking into consideration, among other things, the nature and type of
expense and the relative sizes of the funds.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. These agreements enable
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $800 million,
collectively. Interest is charged to each fund, based on its borrowing, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at
rates ranging from 0.070% to 0.075% per annum based on the average daily unused
portion of the line of credit, is allocated among the participating funds.
The Fund had no borrowing activity for the year ended May 31, 1998.

NOTE B -
MANAGEMENT FEE, ADMINISTRATIVE SERVICES AND
TRANSACTIONS WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent on
an annual basis of 0.40% of the Fund's average daily net asset value.

   Through December 5, 1997, the Adviser had temporarily agreed to limit fund
expenses, including the management fee, to 0.75% and 1.50% of the average net
assets attributable to the Class A and Class B shares, respectively.
Accordingly, during that period, the reduction in the Adviser's fee amounted to
$77,035.

   The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended May 31,
1998, net sales charges received with regard to sales of Class A shares amounted
to $96,964. Out of this amount, $13,316 was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $27,154 was paid
as sales commissions to unrelated broker-dealers and $56,494 was paid as sales
commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

   Class B shares which are redeemed within four years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 3.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the year ended May 31, 1998,
contingent deferred sales charges amounted to $21,713.

   In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A and Class B pursuant to Rule 12b-1 under the Investment
Company Act of 1940. Accordingly, the Fund will make payments to JH Funds for
distribution and service expenses, at an annual rate not to exceed 0.25% of
Class A average daily net assets and 1.00% of Class B average daily net assets
to reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such payments may be service fees as defined by the amended Rules of
Fair Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice, curtailment of a portion of the Fund's 12b-1
could occur under certain circumstances.

   The Board of Trustees approved a shareholder servicing agreement between the
Fund and John Hancock Signature Services, Inc. ("Signature

Services"), an indirect subsidiary of JHMLICo. The Fund pays transfer agent fees
based on the number of shareholder accounts and certain out-of-pocket expenses.

   The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the year was at
an annual rate of less than 0.02% of the average net assets of the Fund.

   Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipione
are trustees and/or officers of the Adviser and/or its affiliates, as well as
Trustees of the Fund. The compensation of unaffiliated Trustees is borne by the
Fund. The unaffiliated Trustees may elect to defer for tax purposes their
receipt of this compensation under the John Hancock Group of Funds Deferred
Compensation Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's deferred compensation liability are recorded on the Fund's
books as an other asset. The deferred compensation liability and the related
other asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investment as well as any unrealized gains or
losses. At May 31, 1998 the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $2,164.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than short-term
obligations, during the year ended May 31, 1998 aggregated $258,656,306 and
$252,506,197, respectively.

   The cost of investments owned at May 31, 1998 (including the joint repurchase
agreement) for federal income tax purposes was $180,272,639. Gross unrealized
appreciation and depreciation of investments aggregated $1,893,411, and
$1,052,603, respectively, resulting in net unrealized appreciation of $840,808.

NOTE D -
REORGANIZATION

On November 12, 1997, the shareholders of the John Hancock Limited-Term
Government Fund ("Limited-Term Government Fund") approved a plan of
reorganization between Limited-Term Government Fund and the Fund providing for
the transfer of substantially all of the assets and liabilities of Limited-Term
Government Fund to the Fund in exchange solely for Class A and Class B shares of
the Fund. The acquisition was accounted for as a tax free exchange of 15,475,727
Class A shares and 996,713 Class B shares of John Hancock Intermediate Maturity
Government Fund for the net assets of Limited-Term Government Fund, which
amounted to $149,668,850 and $9,639,411 for Class A and Class B shares,
respectively, including $1,284,544 of unrealized appreciation, after the close
of business on December 5, 1997.

NOTE E -
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended May 31, 1998, the Fund has reclassified amounts to reflect
a decrease in accumulated net realized gain on investments of $18,339,461, an
increase in undistributed net investment income of $5,549 and an increase in
capital paid-in of $18,333,912. This represents the cumulative amount necessary
to report these balances on a tax basis, excluding certain temporary
differences, as of May 31, 1998. Additional adjustments may be needed in
subsequent reporting periods. These reclassifications, which have no impact on
the net asset value of the Fund, are primarily attributable to certain
differences in the computation of distributable income and capital gains under
federal tax rules versus generally accepted accounting principles.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
To the Board of Trustees and Shareholders of
John Hancock Bond Trust

We have audited the accompanying statement of assets and liabilities of the John
Hancock Intermediate Maturity Government Fund (one of the portfolios
constituting the John Hancock Bond Trust) (the "Fund"), including the schedule
of investments, as of May 31, 1998, and the related statement of operations for
the year then ended, and the statement of changes in net assets and the
financial highlights for each of the periods indicated therein. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

   We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of May
31, 1998, by correspondence with the custodian and brokers, or other appropriate
auditing procedures where replies from brokers were not received. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

   In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
John Hancock Intermediate Maturity Government Fund of the John Hancock Bond
Trust at May 31, 1998, the results of its operations for the year then ended,
and the changes in its net assets and the financial highlights for each of the
indicated periods, in conformity with generally accepted accounting principles.

===============================CHAIRMAN'S MESSAGE===============================

DEAR FELLOW SHAREHOLDERS:

During the last decade, investors have become used to seeing stock market
returns averaging 15% or so each year. In the past three years, the stock market
has treated us to a record run, producing annual returns in excess of 20%.

      After such a long and remarkable performance, many began this year
wondering what the market would do for an encore in 1998. The answer so far has
been more of the same, even with the recent increase in volatility caused by
tremors from Asia. This achievement continues to bolster many investors'
convictions that the market will produce these results forever, or, in the worst
case, that market declines will always be short-lived. While the economy remains
solid and the environment favorable, history and reason tell us it's a highly
unlikely scenario.

      This doesn't mean we know what the market will do next, or that it's
riding for a fall. But after such a run, even in this "new era" of strong
economic growth with low inflation, we believe it would be wise for investors to
set more realistic expectations. As we've said before, markets do indeed move in
two directions. Over the long term, the market's historical results have been
more in the 10% per year range, which is still a solid result, considering it
has been produced despite wars, depressions and other social upheavals along the
way.

- --------------------------------------------------------------------------------

Officer, flush right, next to third paragraph.]
- --------------------------------------------------------------------------------

      In addition to adjusting, or at least re-examining, expectations, now
could also be a good time to review with your investment professional how your
assets are diversified, perhaps with an eye toward a more conservative approach.
Stocks, especially with their outsized gains of the last three years, might have
grown to represent a larger piece of your portfolio than you had originally
intended, given your objectives, time horizon and risk level.

      At John Hancock Funds, our goal is to help you reach your financial
objectives and maintain wealth. One way we can do that is by helping you keep
your feet on the ground as you pursue your dreams.

Sincerely,


/s/ Edward J. Boudreau, Jr.

                     U.S. bond market takes breather in '98,
                              after rallying in '97

Over the past year, most of the action in the U.S. bond market came during the
summer and fall of 1997, when bonds rallied as inflation remained low even
though economic growth was strong. The Asian financial crisis added further
momentum, sending investors fleeing to safe havens like U.S. Treasuries and
setting off global deflation (or falling prices) that helped eliminate lingering
inflation fears here. As bond prices rose, yields on 30-year Treasuries fell
from 6.90% on May 31, 1997, to 5.93% by year end. But by mid-January the rally
was over. For the rest of the winter and spring, bond yields stayed in a narrow
range, buffeted back and forth by the opposing forces of global deflation and
strong domestic economic growth. Yields on 30-year Treasuries hovered between
6.12% and 5.69%.

      As conditions changed, so did the market leaders. During the rally in
1997, Treasuries were the best place to be since they are the most sensitive to
changes in interest rates. Longer-term Treasuries, whose yields reflect
inflation expectations, did especially well. All that changed, however, in
January. With bond prices staying relatively stable, the biggest gainers were
spread securities -- like mortgage bonds and U.S. government agency bonds --
that offer a slight yield advantage over Treasuries. For the year ended May 31,
1998, the Lehman Brothers Treasury Composite Index returned 11.29%, compared to
9.68% for the Lehman Brothers Mortgage-Backed Securities Fixed-Rate Index.

bonds had more of a bumpy ride. Foreign government bonds, which had tumbled
following the Asian crisis, recovered in early 1998. But in late spring, signs
of increasing credit problems in Asia and a decline in U.S. exports to the
region caused them to retreat again.

      John Hancock Government Income Fund weathered these changes well. For the
year ended May 31, 1998, the Fund's Class A and Class B shares had total returns
of 10.82% and 10.01%, respectively, at net asset value. Keep in mind that your
net asset value return will be different from this performance if you were not
invested in the Fund for the entire period and did not reinvest all
distributions. By comparison, the average general U.S. government income fund
returned 10.46%, according to Lipper Analytical Services, Inc.1 For longer-term
performance information, please see pages six and seven.

Fine-tuning asset allocation

The Fund picked up a little ground in several different places. We benefited
from a sizable stake in 10-year and 30-year Treasuries, which outperformed
spread securities early on, as well as shorter-maturity Treasuries throughout
the period. We also had a slightly longer duration than our peers. Duration
measures how sensitive a bond's price is to changes in interest rates. The
longer a bond's duration, the more its price will rise as interest rates fall --
or fall as interest rates rise. As interest rates came down in 1997, the Fund's
longer duration gave it more opportunity for price gains. The Fund's duration,
which began the period at five years, stayed around 5.4 years for most of the
period. Finally, we picked up some extra yield in 1998 by increasing our stakes
in bonds issued by U.S. government agencies and foreign governments.

      Among the U.S. government agencies we owned were mortgage-backed
securities. We boosted our stake in mortgage bonds to 37%, up from 33% at the
end of November. Our main focus was GNMAs with 7.5% and 7% coupons (or stated
interest rates). We pruned our stake in mortgage bonds with coupons of 8% or
higher as interest rates fell and prepayment concerns mounted during December
and early January. Prepayments occur when homeowners pay off their existing
mortgage loans before their due dates and refinance at lower prevailing rates.
We held onto our 11% stake in short-term and long-term collateralized mortgage
obligations, known as CMOs, which carried less prepayment risk than our
traditional mortgage securities. CMOs separate the cash flows of mortgage pools
into various classes with different maturities. Our stake in bonds issued by
other U.S. government agencies also held relatively steady at 10% of net assets.

      In the foreign government sector, our timing worked out well. We had pared
back on foreign government bonds shortly before the Asian crisis. Then, in 1998,
we rebuilt our stake by buying on weakness. Our main addition was to

our existing investment in bonds issued by Hydro-Quebec, the largest electric
utility in the Americas. As Quebec secession concerns again resurfaced, prices
on bonds backed by the province fell and yields rose. Since our purchase, fears
have abated and prices have again risen.

A look ahead

We believe there are two possible scenarios ahead. If the Asian situation
continues to deteriorate, we expect the U.S. economy to slow, interest rates to
fall and bond prices to rally. If Asia's problems begin to fade and U.S. wage
pressures accelerate, we expect a rise in short-term interest rates. To
determine which direction we're headed, we'll be closely watching the Asian
banking system, commodity prices, U.S. wages and corporate earnings growth.
Although it's hard to know what the outcome will be, the first scenario
currently seems most likely. Just recently, we've seen Japanese banks
acknowledging worse non-performing loans, more credit strains from Asian
companies and a noticeable decline in U.S. exports to the Pacific rim.

      We're cautiously optimistic about the bond market's prospects in the next
six months. If Asia's problems continue to multiply, bond investors will start
anticipating a slowdown in the economy. Once this happens, we expect interest
rates to move modestly lower and U.S. bond prices to rally. To position the Fund
for this possibility, we've already lengthened duration slightly to 5.6 years by
selling some of our shorter-maturity Treasuries and buying more 10-year and
30-year Treasuries. If a rally looks increasingly likely, we may increase
duration a bit more. Overall, we expect few dramatic changes in the bond market.
As long as the market continues to remain stable, we'll keep or build our stake
in mortgage and foreign government bonds to take advantage of the extra yield
they offer.

"Overall, we expect few dramatic changes in the bond market."

                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Government Income Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.5%. Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%. Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

The Statement of Changes in Net Assets shows how the value of the Fund's net
assets has changed since the end of the previous period. The difference reflects
earnings less expenses, any investment gains and losses, distributions paid to
shareholders and any increase or decrease in money shareholders invested in the
Fund. The footnote illustrates the number of Fund shares sold, reinvested and
repurchased during the last three periods, along with the corresponding dollar
value.

                   John Hancock Funds - Government Income Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is a diversified open-end management
investment company, registered under the Investment Company Act of 1940, as
amended. The Trust consists of three series: John Hancock Government Income Fund
(the "Fund"), John Hancock High Yield Bond Fund and John Hancock Intermediate
Maturity Government Fund. The other two series of the Trust are reported in
separate financial statements. The investment objective of the Fund is to earn a
high level of current income consistent with preservation of capital by
investing primarily in securities that are issued or guaranteed as to principal
and interest by the U.S. government, its agencies or instrumentalities ("U.S.
government securities").

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A and Class B shares. The shares of each class
represent an interest in the same portfolio of investments of the Fund and have
equal rights to voting, redemptions, dividends and liquidation, except that
certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission and the Internal Revenue Service.
Shareholders of a class which bears distribution and service expenses under
terms of a distribution plan have exclusive voting rights to that distribution
plan.

      Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in joint repurchase agreement transactions. Aggregate cash
balances are invested in one or more repurchase agreements, whose underlying
securities are obligations of the U.S. government and/or its agencies. The
Fund's custodian bank receives delivery of the underlying securities for the
joint account on the Fund's behalf. The Adviser is responsible for ensuring that
the agreement is fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis for both financial
reporting and federal income tax purposes.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $18,749,417 of capital
loss carryforwards available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent such carryforwards are used by
the Fund, no capital gains distribution will be made. The carryforwards expire
as follows: May 31, 2002 -- $13,280,667, May 31, 2004 -- $1,419,401, May 31,
2005 -- $1,964,217 and May 31, 2006 -- $2,085,132. Expired capital loss
carryforwards are reclassified to capital paid-in in the year of expiration.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Interest income on investment securities
is recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

      The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund, if any,
with respect to each class of shares will be calculated in the same manner, at
the same time and will be in the same amount, except for the effect of expenses
that may be applied differently to each class.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates


                                       15

==========================NOTES TO FINANCIAL STATEMENTS=========================

                   John Hancock Funds - Government Income Fund

estimates made by management in determining the reported amounts of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative sizes of the fund.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. These agreements enable
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $800 million,
collectively. Interest is charged to each fund, based on its borrowing, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at
rates ranging from 0.070% to 0.075% per annum based on the average daily unused
portion of the line of credit, is allocated among the participating funds. The
Fund had no borrowing activity for the year ended May 31, 1998.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying instrument or hedge other Fund instruments. At the time the
Fund enters into a financial futures contract, it is required to deposit with
its custodian a specified amount of cash or U.S. government securities, known as
"initial margin," equal to a certain percentage of the value of the financial
futures contract being traded. Each day, the futures contract is valued at the
official settlement price of the board of trade or U.S. commodities exchange on
which it trades. Subsequent payments, known as "variation margin," to and from
the broker are made on a daily basis as the market price of the financial
futures contract fluctuates. Daily variation margin adjustments, arising from
this "mark to market," are recorded by the Fund as unrealized gains or losses.

      When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuation imposed by an exchange.

      For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

      At May 31, 1998, open positions in financial futures contracts were as

      At May 31, 1998, the Fund had deposited in a segregated account $9,263,455
par value of U.S. Treasury Bond, 8.125%, 08-15-19 to cover margin requirements
on open financial futures contracts.

OPTIONS Listed options will be valued at the last quoted sales price on the
exchange on which they are primarily traded. Purchased put or call
over-the-counter options will be valued at the average of the "bid" prices
obtained from two independent brokers. Written put or call over-the-counter
options will be valued at the average of the "asked" prices obtained from two
independent brokers. Upon the writing of a call or put option, an amount equal
to the premium received by the Fund will

be included in the Statement of Assets and Liabilities as an asset and
corresponding liability. The amount of the liability will be subsequently marked
to market to reflect the current market value of the written option.

      The Fund may use option contracts to manage its exposure to the bond
market. Writing puts and buying calls will tend to increase the Fund's exposure
to the underlying instrument and buying puts and writing calls will tend to
decrease the Fund's exposure to the underlying instrument, or hedge other Fund
investments.

      The maximum exposure to loss for any purchased options will be limited to
the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

      Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

      At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's period-end
Statement of Assets and Liabilities.

      There were no written option transactions for the year ended May 31, 1998.

NOTE B -
MANAGEMENT FEE, ADMINISTRATIVE SERVICES AND
TRANSACTIONS WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.65% of the first $200,000,000 of the Fund's
average daily net asset value, (b) 0.625% of the next $300,000,000 and (c) 0.60%
of the Fund's average daily net asset value in excess of $500,000,000.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended May 31,
1998, net sales charges received with regard to sales of Class A shares amounted
to $176,340. Out of this amount, $20,547 was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $141,990 was
paid as sales commissions to unrelated broker-dealers and $13,803 was paid as
sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

      Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the year ended May 31, 1998,
contingent deferred sales charges paid to JH Funds amounted to $272,098.

      In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A and Class B pursuant to Rule 12b-1 under the Investment
Company Act of 1940. Accordingly, the Fund will make payments to JH Funds for
distribution and service expenses, at an annual rate not to exceed 0.25% of
Class A average daily net assets and 1.00% of Class B average daily net assets
to reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such payments may be service fees as defined by the amended Rules of
Fair Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice, curtailment of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

      The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of

JHMLICo. The Fund pays transfer agent fees based on the number of shareholder
accounts and certain out-of-pocket expenses.

      The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

      Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S.
Scipione are directors and/or officers of the Adviser and/or its affiliates, as
well as Trustees of the Fund. The compensation of unaffiliated Trustees is borne
by the Fund. The unaffiliated Trustees may elect to defer for tax purposes their
receipt of this compensation under the John Hancock Group of Funds Deferred
Compensation Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's deferred compensation liability are recorded on the Fund's
books as an other asset. The deferred compensation liability and the related
other asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investment as well as any unrealized gains or
losses. At May 31, 1998, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $7,588.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than short-term
obligations, during the year ended May 31, 1998, aggregated $506,426,797 and
$582,636,390, respectively.

      The cost of investments (including the joint repurchase agreement) owned
at May 31, 1998 for federal income tax purposes was $440,840,282. Gross
unrealized appreciation and depreciation of investments aggregated $16,013,103
and $6,460,743, respectively, resulting in net unrealized appreciation of
$9,552,360.

NOTE D -
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended May 31, 1998, the Fund has reclassified amounts to reflect
a decrease in accumulated net realized loss on investments of $4,273, a decrease
in distributions in excess of net investment income of $866, and a decrease in
capital paid-in of $5,139. This represents the amount necessary to report these
balances on a tax basis, excluding certain temporary differences, as of May 31,
1998. Additional adjustments may be needed in subsequent reporting periods.
These reclassifications, which have no impact on the net asset value of the
Fund, are primarily attributable to certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS 
To the Board of Trustees and Shareholders of 
John Hancock Bond Trust

We have audited the accompanying statement of assets and liabilities of the John
Hancock Government Income Fund (one of the portfolios constituting the John
Hancock Bond Trust) (the "Fund"), including the schedule of investments, as of
May 31, 1998, and the related statement of operations for the year then ended,
and the statement of changes in net assets and the financial highlights for each
of the periods indicated therein. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of May
31, 1998, by correspondence with the custodian and brokers, or other appropriate
auditing procedures where replies from brokers were not received. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
John Hancock Government Income Fund of the John Hancock Bond Trust at May 31,
1998, the results of its operations for the year then ended, the changes in its
net assets and the financial highlights for each of the indicated periods, in
conformity with generally accepted accounting principles.

===============================CHAIRMAN'S MESSAGE===============================

DEAR FELLOW SHAREHOLDERS:

During the last decade, investors have become used to seeing stock market
returns averaging 15% or so each year. In the past three years, the stock market
has treated us to a record run, producing annual returns in excess of 20%. 

      After such a long and remarkable performance, many began this year
wondering what the market would do for an encore in 1998. The answer so far has
been more of the same, even with the recent increase in volatility caused by
tremors from Asia. This achievement continues to bolster many investors'
convictions that the market will produce these results forever, or, in the worst
case, that market declines will always be short-lived. While the economy remains
solid and the environment favorable, history and reason tell us it's a highly
unlikely scenario.

      This doesn't mean we know what the market will do next, or that it's
riding for a fall. But after such a run, even in this "new era" of strong
economic growth with low inflation, we believe it would be wise for investors to
set more realistic expectations. As we've said before, markets do indeed move in
two directions. Over the long term, the market's historical results have been
more in the 10% per year range, which is still a solid result, considering it
has been produced despite wars, depressions and other social upheavals along the
way.

- --------------------------------------------------------------------------------
[A 1 1/4" x 1" photo of Edward J.  Boudreau  Jr.,  Chairman and Chief  Executive
Officer, flush right, next to third paragraph.]
- --------------------------------------------------------------------------------

      In addition to adjusting, or at least re-examining, expectations, now
could also be a good time to review with your investment professional how your
assets are diversified, perhaps with an eye toward a more conservative approach.
Stocks, especially with their outsized gains of the last three years, might have
grown to represent a larger piece of your portfolio than you had originally
intended, given your objectives, time horizon and risk level.

      At John Hancock Funds, our goal is to help you reach your financial
objectives and maintain wealth. One way we can do that is by helping you keep
your feet on the ground as you pursue your dreams.

Sincerely,


/s/ Edward J. Boudreau, Jr.

                              High Yield Bond Fund

                        High-yield bonds post solid gains
               despite Asian turbulence in the year's second half

It was another good year for high-yield bond investors, although not without its
ups and downs. High-yield bonds' fortunes were boosted by the robust U.S.
economy and tame inflation. Demand also remained strong, as investors seeking
income in the continued low interest-rate environment clamored in record numbers
for their higher yields.

      The year turned particularly volatile in the second half, however, in the
wake of the Asian currency and financial troubles that struck world markets in
October. All lower-quality bonds, from the U.S. high-yield bond market to the
emerging markets of Asia and Latin America, went into a tailspin as investors
fled to the safe haven of top-quality U.S. Treasury bonds. In the new year,
solid earnings reports quelled investors' fears and high-yield bonds rallied in
February and March, lifting some of the Latin American markets as well.
High-yield bonds reversed course again in May when Indonesia's problems boiled
over into political unrest and a change in government, provoking further market
quivers.

      In this fluid environment, John Hancock High Yield Bond Fund posted a
strong return on both an absolute and competitive basis. For the year ended May
31, 1998, the Fund's Class A and Class B shares posted total returns of 17.03%
and 16.16%, respectively, at net asset value. Class C shares, which were
introduced on May 1, 1998, returned -1.59% from inception to

Leaders and laggards

We attribute our outperformance to making good securities selections and
avoiding major problems. Some of our cyclical holdings performed well over the
last year, including our steel and paper companies, despite the year-end
turmoil. The catalyst there has been the significant merger and acquisition
activity that is changing the face of the paper industry. We did particularly
well with our Stone Container stock after its announced merger with Jefferson
Smurfit Corp. Overseas, we sold Brazilian paper company Aracruz at a profit,
after having bought the bond earlier in the year when its price fell along with
all emerging-market debt.

      We were not immune to the downturn in May, however, which hit Canadian
paper company Abitibi Consolidated and Indonesian giants Indah Kiat and Asia
Pulp & Paper (APPInternational Finance) as fears grew of a slowdown in paper
demand. We're sticking with these companies, because they remain world-class,
low-cost producers. In the case of the Indonesian paper companies, their large
portion of dollar-based revenues should also shield them from currency moves.
Within the steel group, Alabama-based Gulf States Steel served us well, as did
new addition CSN Iron, a Brazilian company.

      Other winners included Galileo International, which owns the second
largest airline reservation system. Its stock rose as the market recognized its
strong position in a consolidating business where barriers to entry are very
high. Galileo also benefited from its strong international presence. Another
airline stock, top holding Northwest Airlines, didn't fare as well, suffering
all year because of labor issues. We still believe in the airline, and the
potential for further improvements if the merger with Continental goes through.

Strategy

As we have mentioned in our last several reports, the task of finding solid U.S.
high-yield companies that we can buy at attractive prices for the risks we're
taking remains challenging. Careful fundamental analysis and in-depth industry
knowledge -- our specialties -- have become increasingly important requirements
for choosing the best quality deals, as well as the

best companies and managements. What's more, many companies are now selling at
what we consider to be peak earnings potential, which in our view doesn't leave
much margin for error.

      Conversely, we continue to find good values, attractive yields and more
potential for price appreciation among foreign issuers of high-yield bonds. This
coincides with a growing issuance of high-yield bonds by many foreign
corporations, especially from Europe and the big Latin American countries of
Mexico, Argentina and Brazil. As always, we continue to apply the same rigorous
analysis and selection process here.

      Within the last year, we took advantage of the emerging-market downturn to
buy the bonds of some Brazilian companies. That has served us well with such
holdings as industrial giant Trikem, since prices have rebounded since then
after the government took fiscal and monetary steps to regain investors'
confidence. More recently, we bought the bonds of two Japanese banks, Fuji and
Sumitomo. These "Yankee" bonds -- dollar-denominated and issued in the United
States -- carry an attractive yield. Despite Japan's lingering economic
problems, we believe these two banks could now be experiencing the worst of
their bad loans. They have also begun the process of writing off this debt in
order to satisfy international banking requirements, and we believe in their
longer-term outlook for improvement.

Outlook

We are keeping our outlook cautious for high-yield bonds. We remain encouraged
by the prospect of strong demand for high-yield bonds and by the vibrant U.S.
economy. Yet the horizon is not without its potential storm clouds. More
high-yield companies are missing their earnings targets, and there has been an
uptick in defaults over the last year, albeit off a very low base. We're also
monitoring the impact of Asia on the U.S. economy this year. In this
environment, we will continue to search for solid companies that we can buy at
attractive prices and hold, with an eye toward both high current income and
appreciation potential.

"We are keeping our outlook cautious for high-yield bonds."

- --------------------------------------------------------------------------------
                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock High Yield Bond Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.5%. Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%.

Class B performance reflects a maximum contingent deferred sales charge (maximum
5% and declining to 0% over six years).

Class C shares became effective on May 1, 1998 and do not have a cumulative
total return or an average annual total return as of March 31, 1998.

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

- --------------------------------------------------------------------------------
                    WHAT HAPPENED TO A $10,000 INVESTMENT...
- --------------------------------------------------------------------------------

The charts on the right show how much a $10,000 investment in the John Hancock
High Yield Bond Fund would be worth, assuming all distributions were reinvested
for the period indicated. For comparison, we've shown the same $10,000
investment in the Lehman Brothers High Yield Bond Index -- an unmanaged index of
fixed-income securities that are similar, but not identical, to the bonds in the
Fund's portfolio.

Assuming all distributions were reinvested for the same period indicated, a
$10,000 investment in the Fund's Class C shares at inception on May 1, 1998,
would be worth $9,841 without sales charge and $9,741 with maximum sales charge.
For comparison, the same $10,000 investment in the Lehman Brothers High Yield
Bond Index would be worth $9,989. Past performance is not indicative of future
results.

      purchase price and the interest rate of such securities are fixed at trade
      date, although the Fund does not earn any interest on such securities
      until settlement date. The Fund has instructed its Custodian Bank to
      segregate assets with a current value at least equal to the amounts of the
      forward commitments. Accordingly, the market values of $3,168,275 of
      Agrosy Gaming Corp. 13.25%, 06-01-04, $3,150,675 of American Architectural
      Products Corp., 11.75%, 12-01-07, $7,019,250 of SC International Services,

      assets as of May 31, 1998.

(Y)   Parenthetical disclosure of a foreign country in the security description
      represents country of a foreign issuer; however, security is U.S. dollar
      denominated.

(r)   Direct placement securities are restricted to resale. They have been
      valued in accordance with procedures approved by the Trustees after
      consideration of restrictions as to resale, financial condition and
      prospects of the issuer, general market conditions and pertinent
      information in accordance with the Fund's By-Laws and the Investment
      Company Act of 1940, as amended. The Fund has limited rights to

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is an open-end management investment
company, registered under the Investment Company Act of 1940. The Trust consists
of three series: John Hancock High Yield Bond Fund (the "Fund"), John Hancock
Intermediate Maturity Government Fund and John Hancock Government Income Fund
(collectively, the "Funds"). The other two series of the Trust are reported in
separate financial statements. The investment objective of the Fund is to
maximize current income without assuming undue risk by investing in a
diversified portfolio consisting primarily of lower-rated, high-yielding debt
securities.

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A, Class B and Class C shares. The Trustees
authorized the issuance of Class C shares effective May 1, 1998. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses, subject to the approval of the Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

      Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Board of Trustees. Short-term debt investments maturing within
60 days are valued at amortized cost, which approximates market value. All
portfolio transactions initially expressed in terms of foreign currencies have
been translated into U.S. dollars as described in "Foreign Currency Translation"
below.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. Aggregate cash balances
are invested in one or more repurchase agreements, whose underlying securities
are obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investment, to its shareholders. Therefore, no federal income tax provision is
required.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Dividend income on investment securities
is recorded on the ex-dividend date or in the case of some foreign securities,
on the date thereafter when the Fund is made aware of the dividend. Interest
income on investment securities is recorded on the accrual basis. Foreign income
may be subject to foreign withholding taxes which are accrued as applicable.

      The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

and the specific expense rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily identifiable to a specific
fund are allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative size of the fund.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or date of purchase over the life of the security,
as required by the Internal Revenue Code.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. These agreements enable
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $800 million,
collectively. Interest is charged to each fund, based on its borrowing, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at
rates ranging from 0.070% to 0.075% per annum based on the average daily unused
portion of the line of credit, is allocated among the participating funds. The
Fund had no borrowing activity for the year ended May 31, 1998.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying instrument or hedge other Fund instruments. At the time the
Fund enters into a financial futures contract, it will be required to deposit
with its custodian a specified amount of cash or U.S. government securities,
known as "initial margin," equal to a certain percentage of the value of the
financial future contracts being traded. Each day, the futures contract is
valued at the official settlement price of the board of trade or U.S.
commodities exchange on which it trades. Subsequent payments, known as
"variation margin," to and from the broker are made on a daily basis as the
market price of the financial futures contract fluctuates. Daily variation
margin adjustments, arising from this "mark to market," are recorded by the Fund
as unrealized gains or losses.

      When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.

      For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures transactions.

      At May 31, 1998, open positions in financial futures contracts were as
follows:

                                                            UNREALIZED
EXPIRATION    OPEN CONTRACTS                    POSITION   DEPRECIATION

                                                            ===========

      At May 31, 1998, the Fund had deposited in a segregated account $320,000
to cover margin requirements on open financial futures contracts.

FOREIGN CURRENCY TRANSLATION All assets and liabilities initially expressed in
terms of foreign currencies are translated into U.S. dollars based on London
currency exchange quotations as of 5:00 P.M., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain/(loss) on investments are
translated at the rates prevailing at the dates of the transactions.

      The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss from
investments.








      Reported net realized foreign exchange gains or losses arise from sales of
foreign currency, currency gains or losses realized between the


                                       27
<PAGE>

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

trade and settlement dates on securities transactions and the difference between
the amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains or losses arise from changes in the
value of assets and liabilities other than investments in securities at fiscal
year end, resulting from changes in the exchange rate.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS The Fund may enter into forward
foreign currency exchange contracts as a hedge against the effect of
fluctuations in currency exchange rates. A forward foreign currency exchange
contract involves an obligation to purchase or sell a specific currency at a
future date at a set price. The aggregate principal amounts of the contracts are
marked to market daily at the applicable foreign currency exchange rates. Any
resulting unrealized gains and losses are included in the determination of the
Fund's daily net assets. The Fund records realized gains and losses at the time
the forward foreign currency contract is closed out or offset by a matching
contract. Risks may arise upon entering these contracts from potential inability
of counterparties to meet the terms of the contract and from unanticipated
movements in the value of a foreign currency relative to the U.S. dollar.

      These contracts involve market or credit risk in excess of the unrealized
gain or loss reflected in the Fund's Statement of Assets and Liabilities. The
Fund may also purchase and sell forward contracts to facilitate the settlement
of foreign currency denominated portfolio transactions, under which it intends
to take delivery of the foreign currency. Such contracts normally involve no
market risk if they are offset by the currency amount of the underlying
transaction.

      Open foreign currency forward contracts at May 31, 1998, were as follows:

                      PRINCIPAL AMOUNT    EXPIRATION     UNREALIZED

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.625% of the first $75,000,000 of the Fund's
average daily net asset value, (b) 0.5625% of the next $75,000,000 and (c) 0.50%
of the Fund's average daily net asset value in excess of $150,000,000.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended May 31,
1998, net sales charges received with regard to sales of Class A shares amounted
to $4,186,986. Out of this amount, $461,370 was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $3,288,788 was
paid as sales commissions to unrelated broker-dealers and $436,828 was paid as
sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

      Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.00% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the year ended May 31, 1998,
contingent deferred sales charges paid to JH Funds amounted to $1,229,001.

      Class C shares which are redeemed within one year of purchase will be
subject to a CDSC at a rate of 1.00% of the lesser of the current market value
at the time of redemption or the original purchase cost of the shares being
redeemed. Proceeds from the CDSC are paid to JH Funds and are used in whole or
in part to defray its expenses related to providing distribution related
services to the Fund in connection with the sale of Class C shares. For the year
ended May 31, 1998, contingent

==========================NOTES TO FINANCIAL STATEMENTS=========================

                    John Hancock Funds - High Yield Bond Fund

deferred sales charges paid to JHFunds amounted to $18.

      In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.25% of Class A average daily net assets and 1.00% of Class B and Class
Caverage daily net assets to reimburse JH Funds for its distribution and service
costs. Up to a maximum of 0.25% of such payments may be service fees as defined
by the amended Rules of Fair Practice of the National Association of Securities
Dealers. Under the amended Rules of Fair Practice, curtailment of a portion of
the Fund's 12b-1 payments could occur under certain circumstances.

      The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

      The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Funds. The compensation for the year was
at an annual rate of less than 0.02% of the average net assets of each Fund.

      Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S.
Scipione are trustees and/or officers of the Adviser and/or its affiliates, as
well as Trustees of the Fund. The compensation of unaffiliated Trustees is borne
by the Fund. The unaffiliated Trustees may elect to defer for tax purposes their
receipt of this compensation under the John Hancock Group of Funds Deferred
Compensation Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's deferred compensation liability are recorded on the Fund's
books as an other asset. The deferred compensation liability and the related
other asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investment as well as any unrealized gains or
losses. At May 31, 1998, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $1,867.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than obligations of the
U.S. government and its agencies and short-term securities, during the year
ended May 31, 1998, aggregated $1,096,963,353 and $608,676,533, respectively.
Purchases and proceeds from sales of obligations of the U.S. government and its
agencies during the year ended May 31, 1998, aggregated $131,226,563 and
$608,676,533, respectively.

      The cost of investments (including the joint repurchase agreement) owned
at May 31, 1998 for federal income tax purposes was $1,043,686,155. Gross
unrealized appreciation and depreciation of investments aggregated $55,933,003
and $40,496,012, respectively, resulting in net unrealized appreciation of
$15,436,991.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended May 31, 1998, the Fund has reclassified amounts to reflect
a decrease in accumulated net realized gain on investments of $2,897,697, an
increase in accumulated net investment income of $297,517 and an increase in
capital paid-in of $2,600,180. This represents the amount necessary to report
these balances on a tax basis, excluding certain temporary differences, as of
May 31, 1998. Additional adjustments may be needed in subsequent reporting
periods. These reclassifications, which have no impact on the net asset value of
the Fund, are primarily attributable to the treatment of foreign currency gains
and losses, and equalization debits used in the computation of distributable
income and capital gains under federal tax rules versus generally accepted
accounting principles. The calculation of net investment income per share in the
financial highlights excludes these adjustments.

of the periods indicated therein. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of May
31, 1998, by correspondence with the custodian and brokers, or other appropriate
auditing procedures where replies from brokers were not received. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
John Hancock High Yield Bond Fund of the John Hancock Bond Trust at May 31,
1998, the results of its operations for the year then ended, and the changes in
its net assets and the financial highlights for each of the indicated periods,
in conformity with generally accepted accounting principles.
