___talkloudlyinthelibrary.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’tthinkofmoreexamplestosupportthisargument.疑问句中，把can提到句首，将can与主语的位置对调。Canyouspeakanyfore

ignerlanguages?CanyousolvethisMathsproblem?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：MayIleaveworkearlytoday?—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Youmay/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:Wemustobeytheschoolrule

s.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,Im

ustn’tbelate.Youmustn’tforgettophoneJulia.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,youm

ustn’t—不,你不可以走。MustIfinishreadingthebookthisweek?—Yes,youmust—No,youneedn’t典型例析（）1.—_________yourAmericanfriendeatwithchopsticks?—Yes,buthecan’tuset
