一、选择题

1．D

解析：D

【解析】

【分析】

【详解】

句意：——Jenny，我们不需要给母亲买礼物，我们可以从上到下打扫房子。——好主意，

这是母亲节的一个特殊的礼物。A. can’t不能；B. mustn’t禁止；C. shouldn’t不应该；D. needn’t不必。根据题意，表示不必给母亲买礼物。故选D。

2．A

解析：A

【解析】

【详解】

句意：请你说大点声好吗？我不能很好地听到你说的话。考查情态动词辨析。can't不能，表示不能够；mustn't不许，表禁止；shouldn’t不应该，表劝诫；needn’t无需，表示没必要。本句表示“不能够”，根据句意语境，可知BCD三项意思都与句意不合，故选A。3．C

解析：C

【解析】

【详解】

句意：——你认为网上购物安全么？——我觉得是的。淘宝上，消费者可以无理由退货，但是他们要承担运费。

考查情态动词辨析。A. can’t; can不能，能；B. must; must必须，必须；C. can; have to可以，不得不；D. mustn’t; can禁止，能。根据句意表示的是顾客能退货，是可以，第一空用can；但是不得不承担运费，非主观情愿用have to。故选C。

4．A

解析：A

【解析】

【详解】

句意：—温迪现在在教室吗？—我不确定。她可能不在那里，十分钟前我在图书馆见过她。

考查情态动词表推测。may not可能不；must not一定不要；shall not将不会；would not 将要、会、就会，表示虚拟、假设、条件等。根据回答句“I’m not sure”，可推测后句应该是说：她可能不在那里。是对现在情况的推测，may not“可能不”。故选A。

5．A

解析：A

【解析】

【详解】

句意：——那顶帽子是Bob的吗？——不，那不可能是他的。他的是蓝色的。

考查情态动词表推测。can’t 不可能，否定推测；mustn’t 禁止，不表推测；needn’t 不需要；may not 可能不是，表不确定的推测。根据回答“No”和“His is blue.”可知这里说话者表达完全否定推测，故选A。

【点睛】

在情态动词表推测时，很多同学会搞混can’t和mustn’t，认为他们都表示完全否定的推测，在做题时容易误选。can’t 不可能，表示完全否定的推测，但是mustn’t 禁止，并不用于表推测。

6．B

解析：B

【解析】

【详解】

句意：——吉姆坐火车来吗？——我不确定，他可能开自己的车。

考查情态动词辨析。A项，必须，一定，表示肯定推测；B项，也许，表示有可能；C项，需要；D项，应该。根据回答部分I’m not sure.可知，此处并不确定吉姆是开车来还是乘坐火车来，所以此处是“可能”。故选B。

【点睛】

must意为“必须，应该”，可以表示主观上一定要做什么或者肯定推测。例如：I must go home to look after my mum. This pair of shoes must be hers. may意为“可以，也许”，可以表示请求或者推测（无法断定）。例如：May I come in？ It may be hers，but I’m not sure. need意为“需要”，既是情态动词也是行为动词。例如：You needn’t finish your homework right now. You need to tell him the truth. should意为“应该”，表示责任或者义务。例如：You should finish practising playing the piano at first.

7．A

解析：A

【解析】

【详解】

句意：——我戒不掉烟，医生。——为了你的健康，恐怕你必须戒掉。

must必须；can 能，会；may可以；need 需要。根据For your health，可知戒烟有利于健康，是必须的做的事，must表示必须的意思。故选A。

8．D

解析：D

【解析】

【详解】

句意：——抱歉，王老师，我把我的作业落在家里了，我今天必须上交吗？——不，你不需要，你可以明天把它带到这。

考查情态动词辨析；mustn’t表禁止；needn’t不需要；should应该；must必须；may可能；can能，可以，根据Must引导的一般疑问句，否定回答用needn’t，排除A和C，由语境可知，第二个空应该是你可以明天把它带到这，排除B，故选D。

9．B

解析：B

【解析】

【分析】

【详解】

句意：我看不到黑板了。我需要戴眼镜。

考查情态动词。根据后句“I need to have my glasses.”可知看不到黑板，所以需要戴眼镜。can能够；can’t不能够；must必须；mustn’t禁止。根据句意可知，此处表示“不能够”，故

选B。

10．B

解析：B

【解析】

【详解】

句意：火车来的时候你不能跟它一起跑，这很危险。

考查情态动词。may not可能不；mustn’t不能，表禁止；needn’t不需要。根据“It’s dangerous”及语境可知，此处是表达“你不能跟着火车跑”，在这儿应是不允许，强烈的禁止的意思，故用mustn’t。故选B。

11．D

解析：D

【解析】

【分析】

【详解】

句意：——看！史密斯太太正站在教学楼的前面。——不可能是他。她去埃及度假了。

考查情态动词表示推测。must be一定是；mustn’t be禁止是；can be可能是；can’t be不可能是。根据She has gone to Egypt for her holiday.可知她去了埃及，不可能站在教学楼前，故选D。

12．B

解析：B

【解析】

试题分析：句意：——如果我可以这样说，你看起来非常漂亮。must必须；may可以；will 愿意；have to不得不。此处表示允许，故用情态动词may，故选B。

考点：考查情态动词的用法。

13．B

解析：B

【解析】

【详解】

句意：

-南希，你能帮我做英语作业吗？-当然可以。很乐意帮忙。A. could能；B. can能； C. must必须；D. do做。could如果是表示“可能、能够”用于一般过去时态时,回答可用could. 例如：Could he play the piano two years ago? 肯定回答Yes, he could.否定回答No, he couldn't. 如果表示“委婉、请求的语气”,回答用"can"例如：Could I use your computer? 肯定回答用Yes/ Of course, you can.但不能用Yes, you could.否定回答用Sorry, you can't.不用Sorry, you couldn't 。依据句意可知此题是表示委婉、请求的语气，故选B。

【点睛】

could的用法：could如果是表示“可能、能够”用于一般过去时态时,回答可用could. 例如：Could he play the piano two years ago? 肯定回答：Yes, he could.否定回答：No, he couldn't. 如果表示“委婉、请求的语气时”,回答用"can".例如：Could I use your computer? 肯定回答可

用：Yes, you can.但不能用Yes, you could.否定回答可用：Sorry, you can't.不用Sorry, you couldn't .

【解析】

【分析】

【详解】

句意：——我必须现在完成作业吗？——不，你不需要，你可以稍后做。

考查含must的一般疑问句的答语。根据Must提问的一般疑问句，否定回答用needn't，肯定回答用must可知，排除C，由所给空后面的You can do it later可知，应该是否定回答，排除B，故选A。

17．D

解析：D

【解析】

【分析】

【详解】

句意：“当我写下我要感谢的东西时，总是因为钱买不到的东西。”，考查情态动词，A. needn’t不必要；B. shouldn’t不应该；C. may not可能不；D. can’t不能，结合句意，故选D。

18．A

解析：A

【详解】

句意：——吉姆会来扬州度假吗？——他可能会来，这取决于他有多少家庭作业。

考查情态动词辨析。may可能；should应该；must必须，一定；need需要。根据“it depends on how much homework he will have这取决于他有多少家庭作业”可推测，吉姆可能会来。故选A。

19．C

解析：C

【解析】

句意：——Mike明天会来时尚秀吗？——我不确定。他也许不会来。must一定，必须，表示有把握的推测；can可以，能够，表示能力；may也许，可能，表示没有把握的推测；should应该，表示建议。根据I’m not sure.可知此处表示没有把握的推测，故用情态动词may，故选C。

20．C

解析：C

【解析】

【分析】

【详解】

句意：——快点，马克！让我们尽快过马路。——不，你千万不能。你没看见灯还是红色的吗？考查情态动词。A. couldn't不能；B. wouldn't不会；C. mustn't禁止，一定不要；D. needn't不必。根据Don't you see the light is stil l red?“你没看见灯还是红色的吗？”结合常识，可知红灯时横穿马路的行为是被禁止的，故答案选C。

21．C

解析：C

【解析】

【分析】

【详解】

句意：——妈妈，我已经签了一个未来快递的大箱子。里面有什么？——我不确定。可能是你哥哥送的礼物。

考查情态动词。need需要；must必须；may可能；will将会；根据句意理解及前句I’m not sure.可知，这里是对不太确定的事情进行推测，英语中可能性不大的推测用may，故选C。

【点睛】

英语中情态动词有两种用法。一种是本身用法，还有一种是推测用法，表示推测用法时，常用的是must，can和may。must表示推测或推断时，其语气最为肯定，意为“一定”；can 表示推测用法时，常用于否定句和疑问句，多用否定形式，can’t意为“不可能”；may表示推测用法时，多用于肯定句，表示不太确定的可能性的推测，意为“可能，也许”；做题要稍加留意。

22．B

【解析】

【分析】

【详解】

句意：——星期六下午你能来参加我的派对吗？——抱歉，我不能。我可能不得不见我的朋友。

考查情态动词。can’t 不能；might可能，have to不得不；needn’t不需要。根据句意空格处必须是肯定的。可知，此处表示“我可能不得不见朋友。”所以去不了派对，故用might have to，故选B。

最新英语语法情态动词归纳总结 一、单项选择情态动词 1．Mr. Smith is almost on time for everything. How ________ it be that he was late for the meeting? A．can B．should C．may D．must 【答案】A 【解析】 【详解】 考查情态动词辨析。句意：史密斯先生几乎任何事情都是准时的。他怎么可能开会迟到了？ A. can可能，可能性，表示可能性时，常用于否定句和疑问句中，且有时还带有“惊奇、不相信” 等感情色彩。B. should 应该； C. may也许，表示可能性时常用于肯定句中，不用于疑问句中。D.must常用于肯定句中表推测，“一定……”的意思；本题是强调句型的一个变式：强调其特殊疑问句how的形式。根据前句“斯密斯先生几乎是很准时”可推测出“怎么可能开会迟到呢？”。根据句意可知，用于疑问句中的“可能性”且有不相信的色彩，四个选项只有“can”符合题意。故选A 【点睛】 情态动词就是表示说话者对事情的一种看法，也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点，平时要加强记忆。 2．--- Oh, my God!
