brary.A.don’tB.mustn’tC.needn’tD.don’thaveto情态动词概念：情态动词是一种本身有一定的词义，表示说话人的情绪、态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成复合谓语，没有人称和数的变

化。B1情态动词can与cannot我们用can表示某人具备某种能力做某事。如：Icanplaybasketball.Wecanfinishtheworkin20minutes.其否定形式为cannot或can’t.如:Icannotswim.I’mafraidIcan’t

thinkofmoreexamplestosupportthisargument.疑问句中，把can提到句首，将can与主语的位置对调。Canyouspeakanyforeignerlanguages?Canyousolvethi

sMathsproblem?I’msorry,Ican’tB2情态动词may与maynot在请求对方的许可，或是准许你做某事时，常用情态动词may和can.may比较正式，can较常用且更口语化一些。如：MayIleavework

earlytoday?—我今天可以早点下班吗？Yes,Youmay—你可以No,youmaynot—你不可以CanIopenawindow?—我可以开扇窗吗？Yes,youcan—你可以No,youcan’t—你不可以Youma

y/canusemydictionary.你可以用我的词典。Youmaynot/cannotusemycomputer.你不可以用我的电脑。B3情态动词must与mustnotmust用以表示“必须做某事”或“一定要做某事”，具有强制性，表达一种责任或义务或表示很有必要做某事；或在提出建议时使用，

意为“应该；得”。如:Wemustobeytheschoolrules.Thewindowsareverydirty.Imustcleanthem.Wemustgotothebanktoday.Wehaven

’tgotanymoney.must的否定形式是mustn’t,表示“禁止”，“决不允许”，具有强制性。如:Imusthurry,Imustn’tbelate.Youmustn’tforgettophoneJu

lia.must用于一般疑问句中，其肯定和否定回答应引起我们的注意。MustIgonow?—我现在一定要走吗？Yes,youmust.—是的；你一定要走。—No,youmustn’t—不,你不可以走。Mus

tIfinishreadingthebookthisweek?—Yes,youmust—No,youneedn’t典型例析（）1.—_________yourAmericanfriendeatwithchopsticks?—Yes,buthecan’
