DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, New Economy technology stocks dominated the
business-news headlines and the stock market's performance. Red-hot tech stocks
pushed the NASDAQ Composite Index to the stratosphere, as investors
single-mindedly pursued anything technology related. But after setting a new
high on March 10 amid significantly heightened volatility, the tables started to
turn rapidly. Concerns about Microsoft's antitrust ruling and out-of-sight
valuation levels finally triggered waves of selling that sent the index down 32%
from its March high by the end of May.

In this same period, fixed-income-type securities, including bonds and preferred
stocks, struggled as interest rates rose on fears that the roaring U.S. economy
and the rebound of many others around the world would spark an inflation
outbreak.

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

Executive Officer, flush right next to second paragraph.]
--------------------------------------------------------------------------------

While the battle between old and new rages on, a couple of things are clear:
More than ever, diversification and a long-term investment perspective are two
of an investor's best allies. Since not all parts of your portfolio will perform
equally well all the time, we believe it is important to allocate your assets
among different types of investments and funds that target a variety of stock-
and bond-market segments. This strategy, executed under the guidance of a
seasoned investment professional, could provide you with a better chance of both
realizing longer-term results and weathering the market's changing conditions.

Sincerely,


/s/ Maureen R. Ford

            Treasuries make comeback, despite other bonds' woes from
            --------------------------------------------------------
                rising interest rates and inflationary pressures
                ------------------------------------------------

Bond investors fought an uphill battle for much of the past year, as the Federal
Reserve continued to raise short-term interest rates in an effort to restrain
economic growth and keep inflation in control. The federal funds rate - the
interest rate that banks charge each other for overnight loans - climbed from
4.75% in May 1999 to 6.5% a year later. A full percentage point of the increase
occurred after the new year, as inflationary concerns continued to mount. Robust
fourth-quarter gross domestic product numbers that were released in January
initially signaled that economic growth remained strong. Then oil prices rose to
over $30 per barrel -- a level not seen since the 1970s. Strong stock market
gains in the first quarter added concerns that consumer spending would heat up.
Finally, unemployment edged down to 3.9%, increasing the potential for wage
inflation.

Bond market review

As interest rates rose throughout the second half of 1999, bond prices fell,
with mortgage bonds faring better than Treasuries because of their added yield.
This situation, however, began to reverse in February 2000. Thanks to a budget
surplus, the government announced that it would begin buying back longer-dated
Treasuries -- those with 20-year average maturities and coupons (or stated
interest rates) higher than

prevailing rates. Following this announcement, prices on longer-dated Treasury
bonds appreciated significantly. Yields on 30-year Treasuries actually fell
below those on two-year Treasuries for the first time in years. Prices on
longer-dated Treasuries -- those with maturities over 10 years -- climbed,
pushing the Lehman Brothers Treasury Index to a 3.35% return for the year ended
May 31, 2000.

      Rumors that the government might remove its implied backing of bonds
issued by the Federal Home Loan Mortgage Association (Freddie Mac) and Federal
National Mortgage Association (Fannie Mae) also influenced the market. Investors
reacted to the news by fleeing securities issued by both agencies and seeking
safety in Treasuries. This soon hurt all types of bonds with a yield advantage
over Treasuries, including both mortgage bonds issued by U.S. agencies and
non-mortgage agency issues. As yields on these securities rose, their prices
tumbled, leaving the Lehman Brothers Mortgage-Backed Securities Fixed-Rate Index
with a 2.47% return for the year ended May 31, 2000.

Fund performance

John Hancock Intermediate Government Fund benefited during the first half of the
period from favoring mortgage bonds and U.S. government agency bonds over
Treasuries and then moving into longer-dated Treasuries in the second half. For
the year ended May 31, 2000, the Fund's Class A, Class B and Class C shares had
total returns of 2.22%, 1.46% and 1.44%, respectively, at net asset value. By
comparison, the average intermediate-term government fund returned 1.33% during
the same time, according to Lipper, Inc.1 Keep in mind that your net asset value
return will differ from the Fund's performance if you were not invested for the
entire period and did not reinvest all distributions. For longer-term
performance information, please see pages six and seven.

Early yield advantage

During the summer and fall of 1999, we kept a high stake in mortgage bonds
issued by U.S. government agencies. We focused on GNMA bonds with current
coupons of 7% and 7.5% because they are easy to buy and sell. They also carry
less prepayment risk -- the risk that homeowners will pay off their mortgages
early -- than higher- yielding mortgage bonds. Our stake in mortgage bonds did
well during the first half of the fiscal year as investors looked for higher
yields. For similar reasons, we increased our investment in non-mortgage U.S.
government agency bonds to 31% of net assets by the end of November. We trimmed
Treasuries -- which are the most sensitive to changes in interest rates -- to
28% of net assets.

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

Shift toward Treasuries

Following the government's announcement of its buy-back program in February, we
began moving into longer-dated Treasuries. We used cash and the proceeds from
selling five- and 10-year Treasuries to fund our purchases, bringing Treasuries
to 32% of net assets by the end of May. This move lengthened the Fund's duration
-- a measure of interest-rate sensitivity -- from 4.25 years at the end of
November to 4.35 years at the end of May. The longer a bond's duration, the more
its price will fall as interest rates rise -- or rise as interest rates fall.
Fortunately, as yields fell on longer-dated Treasuries, prices appreciated
significantly, with 30-year Treasuries posting a 7.45% return for the six months
ended May 31, 2000. We kept our 37% stake in mortgages, but scaled back slightly
on Freddie Mac and Fannie Mae agencies, even though it seemed unlikely they
would lose their implied government backing. Our stake in non-mortgage bonds
issued by U.S. government agencies was 27% at the end of May.

Positive prospects

Looking ahead, we are optimistic for a couple of reasons. First, the prospect of
more moderate economic growth seems imminent. For the past year, the Federal
Reserve has been vigilantly raising interest rates. Typically, higher interest
rates do not have a measurable economic impact for at least six months. Numbers
released in late April finally began showing slower economic growth. If this
trend continues, we could well be near the top for interest rates, which would
be a plus for the bond market. Second, the bond market has already prepared for
another interest-rate increase of 25 basis points (or one-quarter of a
percentage point), as reflected in current bond yields. Finally, the government
buy-back program should continue to boost prices on longer-dated Treasuries
throughout 2000. We plan to keep the Fund's duration longer than average to take
advantage of this situation. In addition, if the economy continues to show signs
of slowing, we may scale back on some of our mortgage and agency bonds and
increase our stake in Treasuries.

--------------------------------------------------------------------------------
                              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 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 an up-front 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). Class C
performance includes an up-front sales charge of 1% and a contingent deferred
sales charge (1% declining to 0% after one year).

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.

Notes to Performance

      assets attributable to the Class A and Class B shares, respectively.
      Without the reduction of expenses, the average annual total returns for
      the five-year and since inception periods would have been 4.79% and 4.46%,
      respectively, for Class A shares and 4.67% and 4.13%, respectively, for
      Class B shares.

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

The charts on the right show how much a $10,000 investment in the John Hancock
Intermediate 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 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. It is not possible to invest in an index. Past
performance is not indicative of future results.

                John Hancock Funds - Intermediate Government Fund

NOTE A--
ACCOUNTING POLICIES

John Hancock Intermediate Government Fund (the "Fund") is a diversified series
of John Hancock Bond Trust, an open-end management investment company,
registered under the Investment Company Act of 1940. 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, Class B and Class C shares. 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 qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income or excise tax provision is required.
For federal income tax purposes, the Fund has $18,331,510 of capital loss carry
forwards available, to the extent provided by regulations, to offset future net
realized capital gains. If such carry forwards are used by the Fund, no capital
gain distributions will be made. The Fund's carry forwards expire as follows:
May 31, 2001 -- $9,365,539, May 31, 2002 -- $427,159, May 31, 2003 --
$1,950,205, May 31, 2004 -- $1,741,681, May 31, 2005 -- $528,883 and May 31,
2008 -- $4,318,043. Availability of a certain amount of loss carry forwards
which were acquired on September 22, 1995 and December 5, 1997 in mergers, may
be limited in a given year. Additionally, net capital losses of $1,312,592
attributable to security transactions incurred after October 31, 1999 are
treated as arising on the first day (June 1, 2000) of the Fund's next taxable
year.

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 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,


                                       16

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

                John Hancock Funds - Intermediate Government Fund

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. The Fund has entered into
a syndicated line of credit agreement with various banks that enables the Fund
to participate with other funds managed by the Adviser in unsecured lines of
credit with banks, which permit borrowings up to $500 million, collectively.
Interest is charged to each fund, based on its borrowing. In addition, a
commitment fee is charged based on the average daily unused portion of the lines
of credit and is allocated among the participating funds. The Fund had no
borrowing activity for the year ended May 31, 2000.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates, currency exchange 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
futures contract being traded. Each day, the futures contract is valued at the
official settlement price on 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," will be 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/losses can be affected as a result of futures contracts.

      At May 31, 1999, there were no open financial futures contracts.

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 0.40% of the Fund's average daily net asset value.

      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,
2000, up-front sales charges received with regard to sales of Class A shares
amounted to $88,041. Out of this amount, $6,904 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $21,974
was paid as sales commissions to unrelated broker-dealers and $59,163 was paid
as sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Life Insurance Company ("JHLICo"), is the indirect sole shareholder of
Signator Investors.

      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,
2000, contingent deferred sales charges amounted to $198,822.

      Effective May 1, 2000, all Class C retail purchases are assessed a 1.00%
up-front sales charge. For the year ended May 31, 2000, up-front sales charges
received with regard to sales of Class C shares amounted to $200, which was paid
as sales commissions to sales personnel of Signator Investors. 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, 2000,
contingent deferred sales charges paid to JH Funds amounted to $1,033.

      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 C
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 Conduct Rules of the National Association of Securities Dealers. Under
the Conduct Rules, 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 JHLICo. 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,
accounting and legal 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. Stephen L. Brown, Ms. Maureen R. Ford 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. The investment had no impact on the operations of the Fund.

NOTE C--
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than short-term
obligations, during the year ended May 31, 2000, aggregated $549,896,273 and
$583,677,656, respectively.

      The cost of investments owned at May 31, 2000 (excluding the corporate
savings account) for federal income tax purposes was $172,538,168. Gross
unrealized appreciation and depreciation of investments aggregated $22,658 and
$9,133,994, respectively, resulting in net unrealized depreciation of
$9,111,336.

                John Hancock Funds - Intermediate Government Fund

NOTE D--
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended May 31, 2000, the Fund has reclassified amounts to reflect
a decrease in accumulated net realized loss on investments of $2,377 and a
decrease in undistributed net investment income of $2,377. This represents the
amount necessary to report these balances on a tax basis, excluding certain
temporary differences, as of May 31, 2000. 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. The
calculation of net investment income in the financial highlights excludes these
adjustments.

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

===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, New Economy technology stocks dominated the
business-news headlines and the stock market's performance. Red-hot tech stocks
pushed the NASDAQ Composite Index to the stratosphere, as investors
single-mindedly pursued anything technology related. But after setting a new
high on March 10 amid significantly heightened volatility, the tables started to
turn rapidly. Concerns about Microsoft's antitrust ruling and out-of-sight
valuation levels finally triggered waves of selling that sent the index down 32%
from its March high by the end of May.

Executive Officer, flush right next to second paragraph.]
--------------------------------------------------------------------------------

In this same period, fixed-income-type securities, including bonds and preferred
stocks, struggled as interest rates rose on fears that the roaring U.S. economy
and the rebound of many others around the world would spark an inflation
outbreak.

While the battle between old and new rages on, a couple of things are clear:
More than ever, diversification and a long-term investment perspective are two
of an investor's best allies. Since not all parts of your portfolio will perform
equally well all the time, we believe it is important to allocate your assets
among different types of investments and funds that target a variety of stock-
and bond-market segments. This strategy, executed under the guidance of a
seasoned investment professional, could provide you with a better chance of both
realizing longer-term results and weathering the market's changing conditions.

Sincerely,

/s/ MAUREEN R. FORD

                              High Yield Bond Fund

                      Dreary 12 months for high-yield bonds

High-yield bonds made little headway over the last 12 months, as they fought the
twin demons of rising interest rates and investor disinterest. With the U.S.
economy growing at a blistering pace, the Federal Reserve launched an
anti-inflation campaign, raising interest rates six times between last June and
May 2000. As a result, bond prices, which move in the opposite direction of
interest rates, fell. The Fed was trying to slow the economy down to a more
moderate pace that allowed for growth, but would prevent an inflation outbreak.

   Investors were also captivated for much of the past year by high-flying
technology and telecommunications stocks. High-yield bond returns just couldn't
compete and investors left, or ignored, the sector to pursue the lure of the New
Economy. This, combined with a lack of liquidity, drove prices down even
further. Finally, the number of defaults and earnings disappointments at
high-yield companies rose during the year, despite the robust economy.

Fund performance

In this difficult environment, high-yield bond mutual funds had a hard time
breaking even over the last year. For the 12 months ended May 31, 2000, John
Hancock High Yield Bond Fund's Class A, Class B and Class C shares posted total
returns of 0.15%, -0.61% and -0.61%, respectively, at net asset value.
Thankfully, that was bet-

     "...the twin demons of rising interest rates and investor disinterest."

sectors..."

ter than the average high current yield fund's -2.89% return, according to
Lipper, Inc.1 Keep in mind that your net asset value return will be different
from the Fund's performance if you were not invested in the Fund for the entire
period and did not reinvest all distributions. Historical performance
information can be found on pages six and seven.

Energy, paper help Fund outperform

The Fund benefited from its overweighted position in the energy and paper
sectors, which came back to life as the global economy rebounded from 1998's
turmoil. Rising oil prices prompted a renewed interest in drilling and
exploration, to the benefit of oil-service companies R&B Falcon and Key Energy
Services, in which we took some profits when its stock and bonds hit our price
targets. Drilling company Grey Wolf was also a strong performer, with its
dominance in drilling for natural gas, a promising source of fuel. These three
companies have the characteristics we seek in our energy companies. They are
dominant in their specific fields and have the most valuable, sought-after
physical assets where the barriers to entry are high, which keeps demand strong.
Companies like Key Energy have also reaped the rewards of spearheading the
consolidation that has changed and improved its industry.

   Consolidation activity in the paper industry continued to benefit the sector,
allowing the remaining players to boost prices, especially given the lack of new
supply. Having a larger position here than our peers served us well. As merger
activity heated up, the stock and bond prices of long-time holding Repap New
Brunswick rose on speculation that the company would be bought out. When they
reached our target levels, we sold the bulk of our position and locked in
profits. Packaging Corp. of America also served us well when the company took
back some of its preferred stock at an attractive price.

Selectivity counts

In addition to avoiding a number of sectors that produced poor results, like
health care, textiles, specialty retailers and consumer products, we also
managed to steer clear of some of the worst- performing individual companies. As
we mentioned, the number of high-yield companies that failed to execute their
business plans rose in the last 12 months, including such high-profile names as
Iridium and Fruit of the Loom, which we were fortunate not to own, thanks to our
rigorous research. A heightened level of defaults and earnings disappointments
comes with the high-yield bond territory. It's where investors can find the
highest yields, but where the attendant risks of owning companies rated below
investment grade are greater.

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

   While we had fewer disappointments than others, we did not escape altogether.
Pathmark Supermarkets saw its preferred stock and bonds hit hard when a U.S.
antitrust ruling foiled a Dutch company's bid to buy the New York supermarket
chain. Pathmark defaulted on its bonds and is in the process of working out a
financial restructuring package. Coal company AEI Resources also ran into
difficulties over accounting issues and concerns about the negative impact of
pending coal legislation.

Telecom picks

Telecommunications companies make up the largest component of the high-yield
market, and it is the Fund's largest sector weighting as well. The sector got
hit when the environment for technology soured late in the fiscal year and fears
grew that telecom companies might have a harder time getting access to their
next phase of capital in the equity market. We have maintained an underweighted
stance on the sector, since so many telecom companies have yet to deliver
results. We are sticking with companies that display the best ability to grow
revenues and that have good business plans and a market, cost or product
advantage. Currently we like telephone companies in Europe and cell-phone
companies like Nextel Communications -- our biggest holding -- that are
developing the next generation of wireless equipment. We also target merger
candidates.

A look ahead

For now, all eyes are on the economy, waiting for signs that growth has slowed
to the Fed's satisfaction. In the short term, we have some concern that if the
U.S. economy slows too much, high-yield companies could have a harder time
implementing their business plans and making their earnings targets. In this
environment, individual credit selection is more important than ever. We will
continue to apply our in-depth fundamental analysis with an even sharper eye
toward maintaining a portfolio of companies that are worth the extra risk we are
taking to own them. Consolidating industries remain a focus, including the
airlines, where merger activity picked up late in the fiscal year.

"...waiting for signs that growth has slowed to the Fed's satisfaction."

--------------------------------------------------------------------------------
                              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 an up-front 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
performance includes an up-front sales charge of 1% and a contingent deferred
sales charge (1% declining to 0% after one year).

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 and foreign currency 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 two periods, along with
the corresponding dollar value.

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

                    John Hancock Funds - High Yield Bond Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock High Yield Bond Fund (the "Fund") is a diversified series of John
Hancock Bond Trust, an open-end management investment company, registered under
the Investment Company Act of 1940. 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 such as: domestic and foreign corporate bonds; debentures and notes;
convertible securities; preferred stocks; and domestic and foreign government
obligations. As a secondary objective, the Fund seeks capital appreciation but
only when it is consistent with the primary objective of maximizing current
income.

   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 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 qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $35,838,657 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent that such carryforwards are used by
the Fund, no capital gain distributions will be made. The carryforwards expire
as follows: May 31, 2007 -- $21,790,325 and May 31, 2008 -- $14,048,332.
Additionally, net capital losses of $9,556,843 are attributable to security
transactions incurred after October 31, 1999 and are treated as arising on the
first day (June 1, 2000) of the Fund's next taxable year.

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. The Fund may
place a debt obligation on non-accrual status and reduce related interest income
by ceasing current accruals and writing off interest receivables when the
collection of all or a portion of interest has become doubtful. 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,

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

                    John Hancock Funds - High Yield Bond Fund

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 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 funds.

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. The Fund has entered into
a syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund, based on its borrowing. In
addition, a commitment fee is charged to each fund based on the average daily
unused portion of the line of credit and is allocated among the participating
funds. The Fund had no borrowing activity for the year ended May 31, 2000.

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 the "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, 2000, there were no open positions in 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.


                                       29
<PAGE>

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

                    John Hancock Funds - High Yield Bond Fund

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 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 sell contracts at May 31, 2000, were as
follows:

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,
2000, up-front sales charges received with regard to sales of Class A shares
amounted to $324,205. Out of this amount, $60,570 was retained and used for
printing prospectuses, advertising, sales literature and other purposes,
$111,534 was paid as sales commissions to unrelated broker-dealers and $152,101
was paid as sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect parent,
John Hancock Life Insurance Company ("JHLICo"), is the indirect sole shareholder
of Signator Investors.

   Class B shares which are redeemed within six years of purchase will be

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, 2000, contingent deferred sales charges paid to JH Funds amounted
to $3,733,824.

   Effective May 1, 2000, all Class C retail purchases are assessed a 1.00%
up-front sales charge. For the year ended May 31, 2000, the up-front sales
charges received with regard to sales of Class C shares amounted to $7,974. Out
of this amount $7,974 was paid as sales commissions to unrelated broker-dealers
and no commissions were paid to sales personnel of Signator Investors. 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, 2000,
contingent deferred sales charges paid to JH Funds amounted to $40,057.

   In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distributions 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 C
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 Conduct Rules of the National Association of Securities Dealers. Under
the Conduct Rules, 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 JHLICo. 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,
accounting and legal 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. Stephen L. Brown, Ms. Maureen R. Ford 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. The investment had no impact on the operations of the Fund.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales and maturities of securities, other than
obligations of the U.S. government and its agencies and short-term securities,
during the year ended May 31, 2000, aggregated $502,888,748 and $632,583,437,
respectively. There were no purchases or sales of obligations of the U.S.
government and its agencies during the year ended May 31, 2000.

   The cost of investments owned at May 31, 2000 for federal income tax purposes
was $1,201,599,646. Gross unrealized appreciation and depreciation of
investments aggregated $24,122,278 and $308,504,287, respectively, resulting in
net unrealized depreciation of $284,382,009.

NOTE D -
RECLASSIFICATION OF ACCOUNTS

During the year ended May 31, 2000, the Fund has reclassified amounts to reflect
an increase in accumulated net realized loss on investments of $10,506,350 and
an increase in undistributed net investment income of $10,506,350. This
represents the amount necessary to report these balances on a tax basis,
excluding certain temporary differences, as of May 31, 2000. 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
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.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To the Board of Trustees and Shareholders of
John Hancock Bond Trust--
John Hancock High Yield Bond Fund

We have audited the accompanying statement of assets and liabilities of the John
Hancock High Yield Bond Fund (one of the portfolios constituting the John
Hancock Bond Trust) (the "Fund"), including the schedule of investments, as of
May 31, 2000, the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period then
ended 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 auditing standards generally
accepted in the United States. 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, 2000, 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,
2000, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended and the financial

===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:


Over the last 12 months, New Economy technology stocks dominated the
business-news headlines and the stock market's performance. Red-hot tech stocks
pushed the NASDAQ Composite Index to the stratosphere, as investors
single-mindedly pursued anything technology related. But after setting a new
high on March 10 amid significantly heightened volatility, the tables started to
turn rapidly. Concerns about Microsoft's antitrust ruling and out-of-sight
valuation levels finally triggered waves of selling that sent the index down 32%
from its March high by the end of May.

In this same period, fixed-income-type securities, including bonds and preferred
stocks, struggled as interest rates rose on fears that the roaring U.S. economy
and the rebound of many others around the world would spark an inflation
outbreak.

--------------------------------------------------------------------------------
[A 1" x 1" photo of Maureen R. Ford, Vice Chairman, President and Chief
Executive Officer, flush right next to second paragraph.]
--------------------------------------------------------------------------------

While the battle between old and new rages on, a couple of things are clear:
More than ever, diversification and a long-term investment perspective are two
of an investor's best allies. Since not all parts of your portfolio will perform
equally well all the time, we believe it is important to allocate your assets
among different types of investments and funds that target a variety of stock-
and bond-market segments. This strategy, executed under the guidance of a
seasoned investment professional, could provide you with a better chance of both
realizing longer-term results and weathering the market's changing conditions.

Sincerely,

/s/Maureen R. Ford

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

Bond investors fought an uphill battle for much of the past year, as the Federal
Reserve continued to raise short-term interest rates in an effort to restrain
economic growth and keep inflation under control. The federal funds rate - the
interest rate that banks charge each other for overnight loans - reached 6.50%
in May of 2000, up from 4.75% a year earlier. Much of the increase occurred
after the new year, as inflationary concerns continued to mount. Of particular
concern were robust fourth-quarter gross domestic product numbers released in
January, high oil prices throughout the winter, strong first-quarter stock
market gains and falling unemployment levels.

Bond market review

As interest rates rose throughout the second half of 1999, bond prices fell -
with mortgage bonds faring better than Treasuries be- cause of their added
yield. This situation began to reverse, however, in February 2000. Thanks to a
budget surplus, the government announced that it would begin buying back
longer-dated Treasuries - those with 20-year average maturities and coupons (or
stated interest rates) higher than prevailing rates. Following this
announcement, prices on longer-dated Treasury bonds appreciated significantly.
Yields on 30-year Treasuries actually fell below those on two-year Treasuries
for the first time in years. Prices on longer-dated Treasuries - those with
maturities over 10 years - climbed, pushing the Lehman Brothers Treasury Index
to a 3.35% return for the year ended May 31, 2000.

note below the chart reads "As a percentage of net assets on May 31, 2000."]
--------------------------------------------------------------------------------

         Rumors also began circulating that the government might remove its
implied backing of bonds issued by the Federal Home Loan Mortgage Association
(Freddie Mac) and Federal National Mortgage Association (Fannie Mae). Investors
reacted by fleeing securities issued by both agencies and seeking safety in
Treasuries. This soon hurt all types of bonds with a yield advantage over
Treasuries, including mortgage bonds. As yields on these securities rose, their
prices tumbled, leaving the Lehman Brothers Mortgage-Backed Securities
Fixed-Rate Index with a 2.47% return for the year ended May 31, 2000.

Fund performance

John Hancock Government Income Fund benefited during the first half of the
period from favoring mortgage bonds and U.S. government agency bonds over
Treasuries and then moving into longer-dated Treasuries in the second half.
Although we trimmed agencies in the new year, we still retained a high stake in
both mortgages and non-mortgage agency bonds - sectors that historically have
outperformed Treasuries over long periods. This hurt us in the second half of
the period. For the year ended May 31, 2000, the Fund's Class A, Class B and
Class C shares posted total returns of 1.38%, 0.64% and 0.61%, respectively, at
net asset value. By comparison, the average general U.S. government fund
returned 1.08% during the same time, according to Lipper, Inc.1 Keep in mind
that your net asset value return will differ from the Fund's performance if you
were not invested for the entire period and did not reinvest all distributions.
For longer-term performance information, please see pages six and seven.

Early yield advantage

During the summer and fall of 1999, as we mentioned, we added to our stake in
bonds with a yield advantage over Treasuries, focusing mainly on mortgage bonds
issued by the Government National Mortgage Association (GNMA) with stated
interest rates of 6.0% and 6.5%. These issues offered less prepayment risk - the
risk that homeowners would pay off their mortgages early - than higher-yielding
mortgage bonds. We also held on to our stake in collateralized mortgage
obligations (CMOs) - bonds that separate the cash flows of mortgage pools into
various classes with different maturities. Our main change in the first half of
the fiscal year was to boost our investment in non-mortgage U.S. government
agencies. We added mainly callable bonds, which have slightly higher yields than
bonds that cannot be called or redeemed before maturity. We also trimmed
Treasuries to 11% of net assets, selling mostly longer-dated bonds and
shortening the Fund's duration to 5.1 years. This benefited the Fund, since the
shorter a bond's duration, the less its price will fall as interest rates rise.

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

Shift toward Treasuries

Following the government's announcement of its buy-back program in February, we
began shifting back into longer-dated Treasuries. This brought Treasuries to 16%
of net assets by the end of May 2000. It also lengthened the Fund's duration to
5.5 years, slightly longer than the peer group average of 5.25 years. A longer
duration helped the Fund, as yields on longer-dated Treasuries fell and prices
appreciated significantly during the second half. Yields on 30-year Treasuries,
for example, dropped from a high of 6.75% in January 2000 to a low of 5.66% in
April. We kept our 60% stake in mortgages, but scaled back slightly on Freddie
Mac and Fannie Mae agencies, even though it seemed unlikely they would lose
their implied government backing. Our stake in non-mortgage bonds issued by U.S.
government agencies was 13% at the end of May.

Positive prospects

We expect to see more moderate economic growth ahead, which would be good for
the bond market. After a year of Fed interest-rate hikes, we finally began
seeing economic data in late April that showed growth was slowing. The Fed may
still raise interest rates again, but the bond market has already prepared for
another 25-basis- point (or one-quarter of a percentage point) increase, as
reflected in current bond yields. We also expect the government buy-back program
to continue boosting prices on longer-dated Treasuries throughout 2000. We plan
to keep the Fund's duration longer than average to take advantage of this
situation. Once we feel more comfortable that the Fed is done raising interest
rates, we may scale back further on our mortgage and agency bonds and increase
our stake in Treasuries.

                  John Hancock Funds - Government Income Fund

--------------------------------------------------------------------------------
                             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 an up-front 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
performance includes an up-front sales charge of 1% and a contingent deferred
sales charge (1% declining to 0% after one year).

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.

Notes to Performance

(1) Effective December 4, 1998, the Adviser agreed to limit the Fund's
    management fee to 0.50% of the Fund's daily net assets. Without the
    limitation of expenses, the average annual total return for the
    one-year, five-year and since inception periods for Class A shares
    would have been (3.20%), 5.65% and 5.97%, respectively. The average
    annual total return for the one-year, five-year and ten-year periods
    for Class B shares would have been (4.14%), 5.55% and 6.58%,
    respectively. The total return since inception for Class C shares would
    have been (1.19%). Without the reductions of expenses, the yield for
    Class A, Class B and Class C shares would have been 5.78%, 5.31% and
    5.26%, respectively.

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

The charts on the right show how much a $10,000 investment in the John Hancock
Government Income 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 Government Bond Index - an unmanaged
index of fixed-income securities that are similar, but not identical, to the
bonds in the Fund's portfolio. It is not possible to invest in an index. Past
performance is not indicative of future results.

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

Line chart with the heading John Hancock Government Income Fund Class A,
representing the growth of a hypothetical $10,000 investment over the life of
the fund. Within the chart are three lines. The first line represents the Lehman

second line represents the value of the hypothetical $10,000 investment made in
the John Hancock Government Income Fund on September 30, 1994, before sales
charge, and is equal to $14,313 as of May 31, 2000. The third line represents
the value of the same hypothetical investment made in the John Hancock
Government Income Fund, after sales charge, and is equal to $13,669 as of May
31, 2000.

representing the growth of a hypothetical $10,000 investment over the life of
the fund. Within the chart are two lines. The first line represents the Lehman
Brothers Government Bond Index and is equal to $21,088 as of May 31, 2000. The
second line represents the value of the hypothetical $10,000 investment made in
the John Hancock Government Income Fund on May 31, 1990, before sales charge,
and is equal to $18,575 as of May 31, 2000.

Line chart with the heading John Hancock Government Income Fund Class C*,
representing the growth of a hypothetical $10,000 investment over the life of
the fund. Within the chart are three lines. The first line represents the Lehman
Brothers Government Bond Index and is equal to $10,228 as of May 31, 2000. The
second line represents the value of the hypothetical $10,000 investment made in
the John Hancock Government Income Fund on April 1, 1999, before sales charge,
and is equal to $9,996 as of May 31, 2000. The third line represents the value
of the same hypothetical investment made in the John Hancock Government Income
Fund, after sales charge, and is equal to $9,896 as of May 31, 2000.

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 two periods, along with the corresponding dollar
value.

                  John Hancock Funds - Government Income Fund


NOTE A -
ACCOUNTING POLICIES

John Hancock Government Income Fund is a diversified series of John Hancock Bond
Trust, an open-end management investment company, registered under the
Investment Company Act of 1940, as amended. 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, Class B and Class C 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 qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income, which is distributed to
shareholders. Therefore, no federal income tax provision is required. For
federal income tax purposes, the Fund has $137,022,891 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 - $80,627,702, May 31, 2003 - $34,312,457, May 31, 2004 -
$5,561,263, May 31, 2005 - $4,339,751 and May 31, 2008 - $12,181,718.
Availability of a certain amount of these loss carryforwards which were acquired
on September 15, 1995 and December 4, 1998 in mergers, may be limited in a given
year. Additionally, net capital losses of $8,565,680 attributable to security
transactions incurred after October 31, 1999 are treated as arising on the first
day (June 1, 2000) of the Fund's next taxable year.

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

=========================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 appropriated 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 size of the funds.

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. The Fund has entered into
a syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund, based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the year ended May 31, 1999.

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, 2000, open positions in financial futures contracts were as
follows:

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. Effective December 4, 1998, the Adviser
agreed to limit the Fund's management fee to 0.50% of the Fund's daily net
assets. Accordingly, the reduction in the management fee amounted to $870,945
for the year ended May 31, 2000. The Adviser may terminate this limitation in
the future.

         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, 2000, up-front sales charges received with regard to sales of Class A shares
amounted to $232,105. Out of this amount, $19,689 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $84,856
was paid as sales commissions to unrelated broker-dealers and $127,560 was paid
as sales commissions to sales personnel of Signator Investors ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Life Insurance Company ("JHLICo"), is the indirect sole shareholder of
Signator Investors.

         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, 2000,
contingent deferred sales charges paid to JH Funds amounted to $753,942.

         Effective May 1, 2000, all Class C retail purchases are assessed a
1.00% up-front sales charge. For the year ended May 31, 2000, up-front sales
charges received with regard to sales of Class C shares amounted to $70. All of
this amount was paid as sales commissions to sales personnel of Signator
Investors. 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 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, 2000, there were no contingent deferred sales charges paid to JH Funds.

         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 C
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 Conduct Rules of the National Association of Securities Dealers. Under
the Conduct Rules, 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 JHLICo. 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,
accounting and legal 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. Stephen L. Brown, Ms. Maureen R. Ford 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. The investment had no impact on the operations of the Fund.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than short-term
obligations, during the year ended May 31, 2000, aggregated $760,922,371 and
$890,425,750, respectively.

         The cost of investments (including the joint repurchase agreement)
owned at May 31, 2000 for federal income tax purposes was $652,814,721. Gross
unrealized appreciation and depreciation of investments aggregated $2,551,433
and $39,083,442, respectively, resulting in net unrealized depreciation of
$36,532,009.

NOTE D -
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended May 31, 2000, the Fund has reclassified amounts to reflect
an increase in accumulated net realized loss on investments of $6,889,988, a
decrease in distributions in excess of net investment income of $48,592 and an
increase in capital paid-in of $6,841,396. This represents the amount necessary
to report these balances on a tax basis, excluding certain temporary
differences, as of May 31, 2000. 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.

NOTE E -
REORGANIZATION

On November 11, 1998, the shareholders of John Hancock Sovereign U.S. Government
Income Fund (JHSGIF) approved a plan of reorganization between JHSGIF and the
Fund, providing for the transfer of substantially all of the assets and
liabilities of JHSGIF to the Fund in exchange solely for Class A and Class B
shares of the Fund. The acquisition of JHSGIF was accounted for as a tax free
exchange of 30,190,113 Class A shares and 9,178,316 Class B shares of the Fund,
which amounted to $285,764,515 and $86,877,349 for Class A and Class B shares,
respectively, including $11,220,009 of unrealized appreciation, after the close
of business at December 4, 1998. The aggregate net assets of JHSGIF and the Fund
were $372,641,864 and $500,562,839, respectively, immediately before the
acquisition.

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

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, 2000, the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period then
ended 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 auditing standards generally
accepted in the United States. 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, 2000, 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, 2000, the results of its operations for the year then ended,
