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

DEAR FELLOW SHAREHOLDERS:

The financial markets in 1997 have been anything but dull. Bond investors have
enjoyed the benefits of a strong economy with no inflation. Stock investors have
been treated to record-breaking performance by the Dow Jones Industrial Average,
but with record-breaking volatility. After two years of strong advances with
relatively minor swings, the stock market's recent sharp drops and enormous
rebounds have caused a fair share of investor concern.

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

      The latest round came in October and was largely due to uncertainty in
foreign markets. Southeast Asia sneezed and the rest of the world caught a cold.
On October 27, the Dow experienced its largest one-day point decline, dropping
554 points. In percentage terms, however, that roughly 7% decline didn't even
register on the list of 10 largest drops. The next day, the market bounced right
back, as the Dow had a record one-day vault of 337 points. In short order, the
U.S. market had stabilized, yet many markets remained edgy as investors sorted
out the Asian turmoil and its implications on economic growth, interest rates
and corporate earnings.

      In the face of such uncertainty, a trusted investment professional can be
your best ally. Now, more than ever, your investment professional can help you
take the emotion out of investment decisions. At a time when your instincts
might have you react to the heat of the market's moment, your investment
professional can serve as an objective voice to put current events in a
longer-term perspective. He or she can also help you evaluate your investments
in any market environment to ensure that they fit your risk tolerance and time
horizons. On an ongoing basis, your investment professional is there for you to
check out new investment ideas or to get an informed opinion about current
economic and market conditions.

      We encourage you to take advantage of this important resource. Working
together, you can draw up a detailed road map to help reach your financial
destination regardless of the conditions along the way.

Sincerely,


/s/ Edward J. Boudreau, Jr.

               John Hancock Sovereign U.S. Government Income Fund

           Low inflation and shrinking deficit boost U.S. bond prices

A number of events set the stage for strong performance in the U.S. bond market
this past summer and fall. Inflation hovered around 2% and seemed likely to stay
in check. Even as economic growth was strong, commodity prices weakened and the
dollar strengthened compared to foreign currencies. Tax revenues also came in
higher than anticipated in 1997, helping to shrink the government's deficit and
lower issuance of U.S. Treasury bonds. As the Asian currency and credit crisis
spread, many investors moved into U.S. government bonds, which offered higher
yields than some other Western industrialized nations.

      All these forces caused bond yields to fall and prices to rise. Long-term
bonds were the biggest gainers with yields on 10-year Treasuries dropping to
5.87%, down from 6.66% on May 31, 1997. Long-term yields reacted to lower
inflation expectations, while yields on short-term bonds stalled once it became
clear the Federal Reserve had no plans to lower short-term interest rates.

      In this environment, John Hancock Sovereign U.S. Government Income Fund
fared well. For the six months ended November 30, 1997, the Fund's Class A and
Class B shares had total returns of 6.65% and 6.28%, respectively, at net asset
value. By comparison, the average general U.S. government income fund had a

return of 6.44%, according to Lipper Analytical Services, Inc.1 During the same
period, the Lehman Brothers Government Bond Index returned 6.87%. For
longer-term Fund performance information, please see pages six and seven.

Cutting "spread," adding Treasuries

Interest-sensitive U.S. Treasuries turned in the best performance for the period
with the Lehman Brothers Treasury Index returning 6.90%. By contrast, "spread"
securities -- including mortgage bonds and U.S. government agencies -- did not
do quite as well. "Spread" securities offer investors a yield advantage over
Treasuries to compensate them for taking on additional risk. Mortgage bonds in
particular carry prepayment risk -- or the risk that homeowners will prepay
their mortgages before they're due so they can refinance at lower rates. When
interest rates are falling, these added risks cause "spread" securities to lag
Treasuries.

      During the period, we repositioned the Fund to make it more sensitive to
falling interest rates. In July, we extended the Fund's duration to 5.4 years,
up from 5.0 years. 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. At the time, we
lengthened duration to offset the possibility that the durations on our mortgage
bonds would shorten as prepayment fears increased. Unfortunately, a strong
employment report in early August sent interest rates higher for a few weeks,
forcing us to shorten duration temporarily. By month's end, it was back at 5.4
years.

      In July, we also began to cut our stake in "spread" securities. We
lightened up on traditional, fixed-rate mortgage bonds, particularly those with
the highest prepayment risk. In October, when we were fully convinced that
interest rates were coming down, we sold more of these traditional mortgage
bonds, as well as some longer-term collateralized mortgage obligations (CMOs)
and callable U.S. government agencies. CMOs take the cash flows from mortgage
pools and separate them into different classes with varied maturities and
prepayment risk. We owned mainly CMOs that are less sensitive to prepayments.
When interest rates are falling, they tend to do better than traditional
mortgage bonds, but still lag Treasuries. We sold some of these CMOs, but kept a
healthy chunk. At the end of November, we had 45% of our investments in
mortgages, down from 65% at the end of May. We also halved our stake in other
U.S. government agency bonds to 6%, selling mostly long callable bonds. Like
mortgage bonds, these securities run the risk of being "called" or paid off when
the issuer can save money by refinancing at a lower rate.

      We added longer-term Treasuries with maturities over 10 years. By the end
of November, the Fund had 39% of its assets in Treasury bonds, up

rates."

FUND PERFORMANCE
For the six months ended November 30, 1997

[Bar chart with heading "Fund Performance" at top of left hand column. Under the
heading is the footnote: "For the year ended November 30, 1997." The chart is
scaled in increments of 2% from bottom to top, with 8% at the top and 0% at the
bottom. Within the chart there are three solid bars. The first represents the
6.65% total return for the John Hancock Sovereign U.S. Government Income Fund:
Class A. The second represents the 6.28% total return for John Hancock Sovereign
U.S. Government Income Fund: Class B. The third represents the 6.44% total
return for the average general U.S. government income fund. A footnote below
reads: "Total returns for John Hancock Sovereign U.S. Government Income Fund are
at net asset value with all distributions reinvested. The average general U.S.
government income fund is tracked by Lipper Analytical Services, Inc. (1) See

from 19% at the end of May. We also put some money in short-term securities with
maturities under one year. This gave the Fund more of a barbell structure --
with investments at either end of the maturity spectrum. The barbell structure
tends to do better than any other when interest rates are falling.

Positive prospects

Going forward, we plan to keep a slightly longer-than-average duration, a light
stake in mortgages, and a barbell structure. We're staying put because we
believe interest rates will probably decline a bit more and the economy will
eventually grow at a more moderate pace. As long as interest rates are falling,
prepayment risk will continue to be a concern and mortgage bonds will continue
to lag Treasuries. Only when the market reaches a trading range, where yields
are bouncing around in the same area, would we add to our mortgage stake.

      There's also a possibility that the U.S. economy could stay strong longer
than we think. A lot depends on how long the Asian crisis takes to play out and
what kind of effect it has on markets like ours. To determine the economy's
direction, we'll keep a close eye on retail sales and the purchasing managers'
survey, as well as the Japanese economy. Even if the U.S. economy stays strong
longer than we think, we believe it will be temporary and that interest rates
will eventually head back down.

      While the bond market would benefit from falling interest rates, there are
other reasons to expect the good times to continue. Continued strong tax
revenues would again lower the deficit and shrink Treasury issuance. Inflation
expectations are low, and usually don't change quickly. Plus, the United States
offers strong prospects compared to other foreign markets. A stable democracy,
healthy economic growth, and low inflation are all attractions, as are bond
yields that are higher than some other Western industrialized nations. Taking
these factors into consideration, we're optimistic about the bond market's
future.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Sovereign U.S. 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%.

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.

    31.

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.

reported in separate financial statements. The investment objective of the Fund
is to provide as high a level of income as is consistent with long-term total
return by investing in securities issued, guaranteed or otherwise backed by the
United States government, its agencies or instrumentalities.

      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,
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.

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. For federal income tax purposes, the Fund has $48,876,888 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 gains distributions will be made. The carryforwards
expire as follows: May 31, 1998 -- $282,637, May 31, 2002 -- $16,549,431, May
31, 2003 -- $26,193,155, May 31, 2004 -- $3,597,046 and May 31, 2005
- --$2,254,619. 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, INTEREST AND DISTRIBUTIONS Dividend income on investment securities
is recorded on the ex-dividend date. 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 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.

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.

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

           John Hancock Funds - Sovereign U.S. Government Income Fund

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 relative 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.

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 manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and the
relative sizes 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. These agreements enable
the Fund to participate with other Funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $600 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 a
rate of 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 period ended November 30, 1997.

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/or losses can be affected as a result of futures contracts.

      At November 30, 1997 there was the following open position in financial
futures contracts:

                                                           UNREALIZED
EXPIRATION   OPEN CONTRACTS          POSITION              DEPRECIATION

                                                           ============

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 stock
market. Writing puts and buying calls will tend to increase the

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

           John Hancock Funds - Sovereign U.S. Government Income Fund

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 period ended November
30, 1997.

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) 0.50% of the first $500,000,000 of the Fund's
average daily net asset value, and (b) 0.45% of the Fund's average daily net
asset value in excess of $500,000,000.

      John Hancock Funds, Inc. ("JH Funds"), a wholly owned subsidiary of the
Adviser, and Freedom Distributors Corporation ("FDC") act as Co-Distributors for
shares of the Fund. For the period ended November 30, 1997, net sales charges
received on sales of Class A shares of the Fund amounted to $102,389. Of this
amount, $11,803 was retained and used for printing prospectuses, advertising,
sales literature, and other purposes, $20,508 was paid as sales commissions to
unrelated broker-dealers and $70,078 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 for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended November 30,
1997 the contingent deferred sales charges received by JH Funds amounted to
$105,361.

      In addition, to reimburse JH Funds for the services it provides as
distributors of shares of the Fund, the Fund has adopted Distribution Plans 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 0.30% 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 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 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 November 30, 1997, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $2,740.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales and maturities of obligations of the U.S.
government and its agencies, other than short-term securities, during the period
ended November 30, 1997 aggregated $274,162,294 and $296,791,806, respectively.

      The cost of investments owned at November 30, 1997 (including the joint
repurchase agreement) for federal income tax purposes was $374,305,209. Gross
unrealized appreciation and depreciation of investments aggregated $10,890,156
and $784,747, respectively, resulting in net unrealized appreciation of
$10,105,409.

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

DEAR FELLOW SHAREHOLDERS:

The financial markets in 1997 have been anything but dull. Bond investors have
enjoyed the benefits of a strong economy with no inflation. Stock investors have
been treated to record-breaking performance by the Dow Jones Industrial Average,
but with record-breaking volatility. After two years of strong advances with
relatively minor swings, the stock market's recent sharp drops and enormous
rebounds have caused a fair share of investor concern.

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

The latest round came in October and was largely due to uncertainty in foreign
markets. Southeast Asia sneezed and the rest of the world caught a cold. On
October 27, the Dow experienced its largest one-day point decline, dropping 554
points. In percentage terms, however, that roughly 7% decline didn't even
register on the list of 10 largest drops. The next day, the market bounced right
back, as the Dow had a record one-day vault of 337 points. In short order, the
U.S. market had stabilized, yet many markets remained edgy as investors sorted
out the Asian turmoil and its implications on economic growth, interest rates
and corporate earnings.

      In the face of such uncertainty, a trusted investment professional can be
your best ally. Now, more than ever, your investment professional can help you
take the emotion out of investment decisions. At a time when your instincts
might have you react to the heat of the market's moment, your investment
professional can serve as an objective voice to put current events in a
longer-term perspective. He or she can also help you evaluate your investments
in any market environment to ensure that they fit your risk tolerance and time
horizons. On an ongoing basis, your investment professional is there for you to
check out new investment ideas or to get an informed opinion about current
economic and market conditions.

      We encourage you to take advantage of this important resource. Working
together, you can draw up a detailed road map to help reach your financial
destination regardless of the conditions along the way.

Sincerely,


/s/ Edward J. Boudreau, Jr.

         U.S. Treasury bonds rally, while emerging-market bonds stumble

There was good news and bad news for the global bond markets during the past six
months. The good news was that absent inflationary pressures, U.S. interest
rates fell steadily and U.S. Treasury bonds staged an impressive rally. The U.S.
high-yield corporate market -- made up of companies with below-investment-grade
credit ratings -- also performed well. The continued strength of the nation's
economy translated into improving earnings and cash flows for many high-yield
companies. Furthermore, the demand for high-yield bonds was exceptionally strong
throughout the period.

   Outside the U.S. the news was mixed. Government bonds issued by so-called
"dollar bloc" countries --including Canada and New Zealand -- enjoyed gains as
intermediate- and long-term interest rates in their respective countries
declined. Many European bonds posted gains when yields were forced lower as the
continent struggled to meet the economic and fiscal conditions required to join
the European Economic and Monetary Union. Meanwhile, debt issued by companies
and governments in less developed emerging markets experienced a cruel twist of
fate. After soaring and leading their global counterparts throughout the summer,
emerging-market bonds suffered a serious jolt in the fall. In light of currency
and economic instability in Southeast Asia, investors punished nearly every
emerging market by withdrawing their investment dollars and seeking "safe
havens" elsewhere.

TOP FIVE BOND SECTORS

lists five sectors: 1) U.S. Treasury & Government Agencies 21%, 2)

Fund's performance. For the six-month period ended November 30, 1997, the Fund's
Class A and Class B shares posted total returns of 7.15% and 6.78%,
respectively, at net asset value. Those returns outpaced the average
multi-sector income fund, which returned 5.06% for the same six-month period,
according to Lipper Analytical Services, Inc.(1) Please see pages six and seven
for longer-term performance information.

   As you know, the Fund seeks to attain a high level of current income, with
relative price stability, through a flexible investment strategy that allows us
to invest in three broad categories - higher-yielding, lower-rated corporate
bonds; foreign bonds; and U.S. government bonds. The primary reason for our
better-than-average performance was our relatively large stake in high-yield
corporate bonds, which outperformed everything but longer-term U.S. government
securities. Among the Fund's top performers in this area were our media and
telecommunications holdings. Capstar Broadcasting Partners benefited from
consolidation in the radio industry and better advertising revenues, while
telecommunications leader Nextel Communications continued to benefit from rising
subscriber growth. That said, we had a few small positions that turned out to be
laggards during the period. U.K.-based telecommunications provider Ionica
stumbled on questions about the company's subscriber growth and the quality of
its technology. With the cloud of uncertainty hanging over emerging markets,
Brazilian telecommunications concern Globo Communicacoes also faltered.

Strategic changes

Throughout the period, we reduced our foreign bond holdings to 30% of
investments at the end of the period from 37% six months earlier. Part of that
reduction came from selling about half of our stake in Canadian bonds. As
Canadian interest rates dropped, we enjoyed solid performance from these
holdings. But given our view that most of their gains were behind them, we cut
back our holdings. We also made some adjustments in our emerging-market
holdings. Our stake in emerging-market corporate and government bonds stood at
about 19% in early June, which proved rewarding when these bonds enjoyed
impressive gains throughout the summer. But by early October, we became
concerned that currency problems experienced earlier by Thailand in mid-summer
could bode ominously for other emerging markets. In light of our concerns, we
sold many of our government holdings, reducing our emerging markets position to
14% of investments by mid-October. While this helped us sidestep some of the
wreckage from problems that surfaced in Southeast Asia during the last week of
October, we

were unable to sell some securities at prices we thought were reasonable.

   To help mitigate the effects of further turmoil, we bought U.S. Treasury
futures, because it's our view that another round of currency turmoil is likely.
That, in turn, could incite a further flight to quality, with the U.S. Treasury
market as the prime beneficiary. Under that scenario, the prices of our futures
contracts could rise and offset some potential losses in our remaining
emerging-market holdings. We also increased our position in U.S. Treasury bonds
to roughly 16% of investments by the end of the period. In addition to U.S.
bonds' holding "safe-haven" status, U.S. interest rates are high compared to the
rest of the world. We believe there's a good chance that the U.S. economy could
start to slow in 1998, so interest rates could fall further and bonds could
continue to rally.

   As far as Europe goes, we maintained our focus on U.K. bonds, which we think
offer both attractive yields and the potential for price appreciation as
interest rates in that country fall. Meanwhile, we continued to avoid the rest
of Western Europe based on the uncertainty surrounding the move towards a
unified European currency.

Outlook

In our view, 1998 is shaping up to be an interesting year for global bonds. We
believe that there could be continued volatility arising from further currency
problems in emerging markets. As a result, we're likely to keep our stake there
relatively low until we think that the currency crises are behind us.
Furthermore, there's a good chance that recent and future devaluations of
emerging-market currencies will be the catalyst for slower worldwide economic
growth. Even though we expect the U.S. economy to slow as well, we believe our
economy will remain in positive territory. Our view is that high-yield U.S.
corporate bonds could post solid performance again next year. Granted, we don't
expect to see a lot of capital appreciation from high-yield bonds, and expect
that most of their total return will be generated from their interest payments.
Against a slower economic backdrop in the United States, we also believe
interest rates could continue to decline.

"...1998 is shaping up to be an interesting year for global bonds."

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Strategic 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 September 28, 1989, different sales charge schedules
were in effect for Class A shares and are not reflected in the performance
information.

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. For a discussion of risks
associated with international investing and high-yield bonds, please see the
Fund's prospectus.

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

                   John Hancock Funds - Strategic Income Fund

(UNAUDITED)

NOTE A -
ACCOUNTING POLICIES

John Hancock Strategic Series (the "Trust") is an open-end management investment
company, registered under the Investment Company Act of 1940. The Trust consists
of two series of portfolios: John Hancock Strategic Income Fund (the "Fund") and
John Hancock Sovereign U.S. Government Income Fund. The investment objective of
the Fund is a high level of current income.

   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. All portfolio
transactions initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Foreign Currency Translation"
below. The Fund may invest in indexed securities whose value is linked either
directly or inversely to changes in foreign currencies, interest rates,
commodities, indices or other reference instruments. Indexed securities may be
more volatile than the reference instrument itself, but any loss is limited to
the amount of the original investment.

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,
may participate in a joint repurchase agreement transaction. Aggregate cash
balances are invested in one or more large 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. Capital gains realized
on some foreign securities are subject to foreign taxes and are accrued, as
applicable.

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. It
will not be subject to Federal income tax on taxable earnings which are
distributed to shareholders. For federal income tax purposes, net currency
exchange gains and losses from sales of foreign debt securities may be treated
as ordinary income even though such items are capital gains and losses for
accounting purposes. The Fund has $29,587,682 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 gains distributions will be made. The carryforwards expire as follows:
May 31, 1999 -- $8,553,157, May 31, 2002 -- $454,810, May 31, 2003 --
$20,312,807 and May 31, 2004 -- $266,908. Expired capital loss carryforwards are
reclassified to capital paid-in, in the year of expiration.

DIVIDENDS, INTEREST AND DISTRIBUTIONS 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 distribu-


                                       25

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

                   John Hancock Funds - Strategic Income Fund

tions 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 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 the 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 an unsecured
line of credit with banks which permit borrowings up to $600 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 a
rate of 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 period ended November 30, 1997.

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 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 other than that offset by the currency amount of the underlying
transaction.

   Open foreign currency forward contracts at November 30, 1997 were as follows:

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/or losses can be affected as a result of futures contracts.

   At November 30, 1997, open positions in financial futures contracts were as
follows:
                                                               UNREALIZED

                                                                ========

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 stock 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, 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 period ended November 30,
1997.

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) 0.60% of the first $100,000,000 of the
Fund's average daily net asset value, (b) 0.45% of the next $150,000,000, (c)
0.40% of the next $250,000,000, (d) 0.35% of the next $150,000,000, and (e)
0.30% of the Fund's average daily net asset value in excess of $650,000,000.

   The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended November
30, 1997, net sales charges received with regard to sales of Class A shares
amounted to $962,509. Out of this amount, $113,792 was retained and used for
printing prospectuses, advertising, sales literature and other purposes,
$454,003 was paid as sales commissions to unrelated broker-dealers and $394,714
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 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 period ended November 30,
1997, contingent deferred sales charges paid to JH Funds amounted to $405,981.

   In addition, to reimburse JH Funds for the services they provide as
distributors of shares of the Fund, the Fund has adopted Distribution Plans 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 the JH Funds
for distribution and service expenses, at an annual rate not to exceed 0.30% of
Class A average daily net assets and 1.00% of Class B average daily net assets
to reimburse the JH Funds for their 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 a
transfer agent fee 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., Mr. Richard S. Scipione, and Ms. Anne C. Hodsdon
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 will make 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 November
30, 1997, the Fund's investments to cover the deferred compensation liability
had unrealized appreciation of $3,524.
