情态动词表示说话人对某一动作或状态的态度，可表示“可能”、“可以”、“需要”、“必须”或“应当”等之意。
can/culd may/might must shall/shuld will/wuld need have t
能够可能必须应该意愿需要不得不
must/must nt
（1）表示能力时，意为“能够，会”，如：—Can yu play the pian?你会弹钢琴吗？ —N，I can't.不，我不会。（2）表示允许、请求时，culd比can 语气更加委婉客气，常用于“Culd I / yu …?”句型中，若表示同意时，用can回答而不用culd。如：— Culd I use yur pen?我可以用你的钢笔吗?— Yes, yu can.可以。（3）can’t意为“不能，不会”，也可用于表示推测，意为“不可能”。如：Mr Smith can't be at hme.史密斯先生不可能在家。
1.culd是can的过去式，意为“能；会”，表示过去的能力。He culd play the pian when he was 5. 当他5岁时，他就会弹钢琴了。2.在表示请求许可时，can，culd没有时态区别，只是culd在语气上更加委婉客气。—Culd I use yur dictinary? 我可以用你的字典吗？—Yes, yu can. 可以。
(2017河北) I have travelled a lt. I________ speak fur languages. A. can B. mayC. must D. need【解析】考查情态动词。此处can表示具有某种能力，意为“能；会”。其他选项没有此用法。
(2017温州) We've rdered t much fd. I ________eat any mre. —Never mind. Let's take it hme. A. can't B. mustn't C. needn't D. shuldn't【解析】 ——我们点了太多食物。我不能再吃了。——没关系。我们带回家。此处can't意为“不能”。
(1) 表示允许、请求时用法与can相似。在回答以may引起的问句时，肯定回答一般不用may这个词，而用其他方式，如“Yes, please.”或“Certainly.”，否定回答用can’t或mustn’t, 不能用may nt。如：—May I cme in？我可以进来吗？ —Sure.当然(可以)。(2) 表示推测，意为“可能，也许”，常用于肯定句中。如：The watch may be Mary's.这块手表可能是玛丽的。
2.may的过去式为might，表示推测时两者无时态区别，不过might的可能性低于may。He might be sick.他可能是生病了。
1.may还可表示推测，谈论可能性，意为“可能；或许”，一般用于肯定句中。It may rain tmrrw. 明天可能会下雨。
3.表示希望、祈求、祝愿时，may常译为“祝愿”，通常结构为“may+主+v.”。May yu have a gd time！祝你玩得开心！
( 2017·西宁 )—What will the weather be like tmrrw?—It________be rainy,cludy r sunny.I’m nt sure. A.mustB.shuldC.can’tD.might【解析】考查情态动词。根据“I’m nt sure.”可知,空处表示“有可能”。可知应用情态动词might。【答案】 D
(1) 表示义务，意为“必须”（主观意志）；否定形式 mustn’t, 意为“禁止，不允许”“一定不要；千万别”。在回答以must引起的问句时，肯定回答用must，否定回答用needn’t或dn’t have t，不能用mustn’t。如：—Must I g nw？我现在必须去吗？—Yes，yu must.是的，你必须去。(N，yu needn't./N，yu dn't have t.不，你不必。)Yu mustn't play ftball n the rad.你不许在公路上踢足球。（2）must和must be 都表示揣测，意为“想必，准是，一定”，只用于肯定句中。如：The bk must be Lily's because there's her name n the cver.这本书一定是莉莉的，因为封面上有她的名字。
( 2017·北京 )—________I hand in the reprt tday? —N,yu needn’B.MustC.ShallD.Culd【解析】考查情态动词。句意:——今天我必须交报告吗?——不,你没有必要。根据答语“N,yu needn’t.”可以判断,前面是must引导的一般疑问句。故选B。
