Imustfinishtheworkbeforenine.--MustIfinishtheworkbeforenine?---Yes,youmust./No,youneedn’t.情態動詞must的用法⑵mustn’t表示禁止，意思是“不可以，不要”。由may引起的疑問句，肯定回答用may，否定回答用mustn’t。

Youmustn’tcomelatetomorrow.—MayIhandinthepapernexttime?—Yes,youmay./No,youmustn’t.兩者都表示必須，但must側重于說話者的主觀看法，認為有必要或有義務去做某事，haveto側重于客觀需要，含有“不得不，被迫”之意。Allpassengersmustwearseatbelts.

所有乘客都要系安全帶。Mybikewasbrokenyesterday,soIhadtowalktoschool.昨天我的自行車壞了，所以我只能走路去學校。must和haveto的區別注意：在表示客觀需要時一般用haveto(不得不)，而不用must。

用于否定句時，must的否定式mustnot(mustn’t)表示“一定不要，不允許”；而haveto的否定式donot(don’t)haveto表示“不必”（=needn’t）。Youmustn’ttellhimaboutit.（可能是秘密）Youdon’thavetotellhimaboutit.（他可能知道了或者沒有必要讓他知道）()—Ican’tstopsmoking,doctor.—Foryourhealth,I’mafraidyou______.(2011貴州安順)A.may B.can

C.haveto D.need[解析]句意“--醫生，我不能戒煙。--為了你的健康，恐怕你不得不”。may意為“可以”、can意為“能夠”、need意為“需要”均不符合句意。C表示允許，意思是“可以，能夠，許可”；可用于肯定句、否定句和疑問句中。其否定形式是cannot(can’t)，表示“不能，不可以”，語氣弱于mustnot(mustn’t)。情態動詞can的用法Youcan’tputthemilkfirst.(沒有禁止的含義)CanIhavealookatyourphoto?我可以看一下你的照片嗎？Practice()1.—CanIgofishingwithyou,Dad?
