高中英语情态动词技巧(很有用)及练习题含解析一、单项选择情态动词1．What a pity! Considering his ability and experience, he ___________ it better.A．need have done B．must have doneC．can have done D．might have done【答案】D【解析】【详解】考查虚拟语气中的情态动词。

句意：真遗憾啊！考虑到他的能力和经验，他也许可以做得更好。

can have done较少使用此结构，表示对过去行为的怀疑；用于疑问句时意为“难道真的做了吗”，表示怀疑；need have done需要做某事，实际上却未做（表示虚拟语气）；must have done一定做了某事（表示对过去发生的事情的肯定推测）；might have done表示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。

故D正确。

【点睛】本题是高考必考考点，一定要牢记句型意思。

must have done过去肯定做了某事。

should have done本应该做而实际未做。

can’t have done过去不可能做了某事；shouldn’t have done 本不应该做而实际做了。

need have done本有必要做某事而没做；needn’t have done本没有必要做某事；注意没有mustn’t have done的形式。

“can”表示有能力或有机会做某事，在这里表示如果你完成作业就有机会来参加今晚的派对。

“could”和“might”语气较委婉，“may”通常表示可能性。

在这个语境中，强调有能力和机会，用“can”最合适。

同样，这里强调如果她努力学习就有能力通过考试，“can”表示能力。

“could”“might”语气委婉，“may”表示可能性，这里突出能力，所以选“can”。

3. you help me with this math problem?A.CanB.CouldC.May答案解析：B。

这里用“could”表示委婉地请求，“can”语气较直接，“may”和“might”在这个语境中不太符合请求的语气。

“may”用于请求许可比较正式，“can”也可以用于请求但相对不那么正式，“could”和“might”语气委婉但在这里不太符合直接请求的语境。

5. he come to school late today?A.CanB.CouldC.MayD.Might答案解析：D。

“might”在这里表示对可能性的较小推测，他今天有可能会迟到吗？“can”和“could”通常不用于这种较小可能性的推测，“may”也不太符合这个语境。

6. you lend me your pen?A.CanB.CouldD.Might答案解析：B。

“could”表示委婉地请求借笔，“can”语气较直接，“may”和“might”不太符合请求借东西的语境。

句意：——你昨天参加实验项目的会议了吗?——是的，但我想我（本来）不需要，因为我的主管在那里。

Think/suppose 等宾语从句中如果有否定词时，要把从句的否定词 not 前移，即“否定前移”。

所以 not 是从句中的否定词。

“need have done ”意为“本来有必要做而未做”；“ needn ’ t have done指过去”本来没必要做而做了。

根据上一句时间状语“yesterday可”知本句指的是过去发生的事。

结合第二句“because my director was there( 我的主管 )在”可推断出，我本来不必要去。

故选D。
