===============================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.

               Tame inflation, moderate economy trigger bond rally

Bond investors fared well over the last six months, as interest rates mostly
moved down and prices rose. When the period began in June, bonds were rallying
on economic data that suggested growth was slowing from its torrid first-quarter
pace and that inflation remained tame. In mid July, however, volatility
increased and bonds had a setback when monthly economic data suggested the
economy was picking up steam. Yet for all investors' fears, inflation remained
dormant, and bonds turned upward again in early September and maintained their
march through the period's end. In large part the bond surge reflected the
market's growing confidence in the notion that the Federal Reserve was not going
to raise interest rates again to slow down the economy, given its moderating
pace and subdued inflation. Other factors keeping the Fed neutral were the
strength of the U.S. dollar, which eroded the overseas profits of multinational
companies, and the credit and currency woes that struck Southeast Asia in the
summer. These events served to further ease U.S. inflation fears.

    Yet the shock waves in the Pacific Rim reverberated throughout world markets
in October, after the fears of currency devaluations spread to Latin America. As
equity markets plunged worldwide, investors in a classic "flight to safety"
headed for the security of the more stable U.S. market, and U.S. Treasury bonds
in particular. In this brief period, U.S. corporate bonds -- both
investment-grade and lower-rated high-yield bonds -- saw their prices drop
sharply compared to Treasuries, cutting short their uphill charge.
Emerging-market bonds were hardest hit by the turbulence. By the end of
November, however, stability returned to most of the U.S. corporate market,

As a percentage of net assets on November 30, 1997
- --------------------------------------------------------------------------------

while uncertainty still abounded in the emerging markets.

    Despite the late-period turbulence, it was a rewarding time for bond
investors, and John Hancock Sovereign Bond Fund was no exception. For the six
months ended November 30, 1997, the Fund's Class A and Class B shares posted
total returns of 6.38% and 6.01%, respectively, at net asset value. Those
results were in line with the 6.58% return of the average corporate debt A-rated
fund, according to Lipper Analytical Services, Inc.(1) Longer-term performance
can be found on pages six and seven.

Timely moves, defensive strategy pay off

We believe that the key to the Fund's steady long-term performance lies in our
in-depth research analysis that helps us both anticipate market moves and know
which credits to buy and to avoid. What's more, we maintain such a highly
diversified portfolio that the Fund feels the effects less when any sector or
specific credit has a downturn.

    Our timely moves this period helped us successfully maneuver through the
late-period pitfalls. We sold some of our corporate bonds in anticipation that
their prices, which had risen steadily with the robust U.S. economy, would begin
to come down as turbulence increased. In particular, we avoided the most
volatile emerging markets, including Thailand, Malaysia and Korea, by selling
our small positions there ahead of the worst turmoil. In early summer, for
example, we sold a Bangkok Bank bond for only slightly less than what we had
paid for it earlier in the year. By the end of October, its price had plunged as
the spread, or difference, between its yield and that of U.S. Treasuries widened
from 155 basis points (1.5%) when we bought it, to more than 600 basis points
(6.0%) at the end of November. We also eliminated our small exposure to Hong
Kong. Although we didn't completely escape price declines as we sold our stake,
we managed to keep our losses down.

    In their place, we upped our stake in U.S. Treasury and government agency
bonds, which rose to 29% of the Fund's net assets. That defensive strategy
served us well in October and November as Treasuries were the biggest
beneficiaries of the market concerns. Once we felt that bond prices had bottomed
out, we tried to capture the upswing by buying some U.S. high-grade corporate
bonds that had been particularly hard hit, many of them unfairly so given their
solid credits. We've already seen some prices rebound. Furthermore, we bought
some new-issue high-yield bonds that came to the market at attractive prices
amid the market's hysteria.

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
6.38% total return for John Hancock Sovereign Bond Fund: Class A. The second
represents the 6.01% total return for John Hancock Sovereign Bond Fund: Class B.
The third represents the 6.58% return for the average corporate debt A-rated
fund. The footnote below states: "Total returns for John Hancock Sovereign Bond
Fund are at net asset value with all distributions reinvested. The average

all distributions reinvested. The average corporate debt A-rated fund is tracked

historical performance information.
- --------------------------------------------------------------------------------

know, we maintain the Fund's average A credit rating by investing in a mix of
U.S. government bonds, investment-grade corporate bonds and, to a lesser extent,
high-yield bonds whose credit ratings are below investment grade.

    As we mentioned earlier, high-yield bonds, including those in emerging
markets, were hardest hit at the end of the period, and the Fund was not immune
to that downturn. Most notably, our Brazilian corporate bonds, such as rail
transport company MRS Logistica and Voto-Votorantim Overseas Trading Operations,
a major conglomerate, suffered price drops. Our bonds of Indonesian paper
company Indah Kiat also suffered by association with its country's woes. Yet we
remain convinced that these world-class companies are likely to withstand the
currency volatility, given their strong sources of dollar-based revenues.

A look ahead

In our view, there is still room for interest rates to come down more and for
bonds to do well in 1998. Recent worldwide events suggest that the trend is
toward slower, rather than faster, economic growth. As the Asian countries try
to export their way back to financial health, their weaker currencies and
therefore less expensive products will keep the pricing pressure on -- and
inflation low. Given this scenario, it's fairly certain that the Fed will stay
on the sidelines for now and not raise rates again. In fact, the next move could
even be a rate decrease, something the market could begin to anticipate
happening some time in 1998.

    With this outlook, we'll keep the Fund's duration -- a measure of the Fund's
sensitivity to changes in interest rates -- neutral or slightly longer to
capture the benefits of any more rate drops. The longer the duration, the more
the Fund's share price moves with changes in interest rates. Credit selection
will remain as important as ever, since a slowdown in economic growth could put
pressure on corporate bond prices later in the year. For now, we'll minimize our
investments in the emerging markets until there are further signs that the
crisis has passed. Until then, heavier exposure to this sector would present too
much volatility for this type of fund.

"...there is still room for interest rates to come down more..."

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

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

For Class A shares, total return figures include a maximum applicable sales
charge of 4.5%. 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.

                    John Hancock Funds - Sovereign Bond Fund

(UNAUDITED)

NOTE A --
ACCOUNTING POLICIES

John Hancock Sovereign Bond Fund (the "Fund") is a diversified open-end
investment management company, registered under the Investment Company Act of
1940. The investment objective of the Fund is to generate a high level of
current income, consistent with prudent investment risk, through investment in a
diversified portfolio of freely marketable debt securities.

    The Trustees have authorized the issuance of multiple classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, dividends and liquidation, except that certain expenses,
subject to the approval of the Trustees, may be applied differently to each
class of shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a class
which bears distribution and service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such 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 $29,796,705 of a capital
loss carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent that such carryforward is used
by the Fund, no capital gain distributions will be made. The carryforward
expires as follows: May 31, 1999 -- $755,945, May 31, 2001 -- $10,107,031, May
31, 2002 -- $9,347,493, May 31, 2004-- $8,402,805 and May 31, 2005 --
$1,183,431. Expired capital loss carryforwards are reclassified to capital
paid-in in the year of expiration.

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

    The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund 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.

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

                    John Hancock Funds - Sovereign Bond Fund

daily at the class level based on the appropriate net assets of each class and
the specific expense rate(s) applicable to each class.

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

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. These agreements enable
the Fund to participate with other Funds managed by the Advisor 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 year ended November 30, 1997. 

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

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

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

    There were no open positions in financial futures contracts.

NOTE B --
MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly fee to
the Adviser for a continuous investment program equivalent on an annual basis to
the sum of (a) 0.50% of the first $1,500,000,000 of the Fund's average daily net
asset value, (b) 0.45% of the next $500,000,000, (c) 0.40% of the next
$500,000,000 and (d) 0.35% of the Fund's average daily net asset value in excess
of $2,500,000,000.

    The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the period ended November
30, 1997, JH Funds received net sales charges of $711,879 with regard to sales
of Class A shares. Out of this amount, $82,583 was retained and used for
printing of prospectuses, advertising, sales literature and other purposes, and
$175,925 was paid as sales commissions to unrelated broker-dealers and $453,371
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

                    John Hancock Funds - Sovereign Bond Fund

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 received
by JH Funds amounted to $148,784.

    In addition, to reimburse JH Funds for the services it provides as
distributor 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 these payments may be service fees as defined by the amended Rules of
Fair Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice curtailment of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

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

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

    Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipione
are 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 investment to cover the deferred
compensation had unrealized appreciation of $11,737.

NOTE C --
