一、选择题

1.C

解析:C

【解析】

句意:现在11点了,皮特还没有来,他的妈妈一定很生气了。A. may也许; B. can可能;一般用于否定句; C. must一定;一般用于肯定句; D. need需要。根据It is 11:00 p.m now.可知,表示对现在的推测,根据Peter hasn't come back yet. 可知,可推测妈妈一定生气了。推测的可能性很大,故选C。

2.B

解析:B

【解析】

【详解】

句意:——你听说过2020年地球的温度将上升到59摄氏度吗?——不要担心。那个消息可能不是真的。

考查情态动词。must not禁止;may not可能不是。needn’t不必;will not将不会。根据“Don’t worry”可知,这里是这个消息可能不是真的,表示一种推测。根据题意,故选B。3.C

解析:C

【解析】

【详解】

句意:--听! 狼在叫! --它不可能是狼,因为狼从来不会在这个时候出来。

A. mustn’t禁止;

B. needn’t没有必要;

C. can’t不可能;

D. don’t构成一般现在时的否定句。根据“because a wolf never comes out at this time因为狼从来不会在这个时候出来”,可推断它不可能是狼,故选C。

【点睛】

情态动词表推测的用法:can表示“可能”;can’t表示“不可能”;may表示“可能”,must表示“一定”,注意mustn’t表示“禁止”不表示推测,表示否定推测要用can’t.

4.C

解析:C

【解析】

【详解】

句意:乔的生日我给她买了一条漂亮的项链。她可能会喜欢,但是我不确定。

考查情态动词表示推测。can表示能、可以;may表示可能,might是其过去式;must表示一定、必须。根据题干中but I'm not sure.可知可能性较小的推测,则可用may或者might,B项中may后有系动词be,原句中有动词like,则只能用might。故选C。

5.D

解析:D

【解析】

【分析】

【详解】

句意:——妈妈,我今天必须完成作业吗?——不,你不必这么做。明天是星期天,你今天可以休息一下。考查情态动词辨析。A. shouldn’t不应该,表建议;B. mustn’t一定不,表禁止;C. can’t不能,表示不允许;D. don’t have to不必,指没有必要。回答must引起的一般疑问句,如果要作否定回答,一般是用needn’t(不能用mustn’t)或not have to。根据句意语境,可知选D。

6.A

解析:A

【解析】

【详解】

句意:你看起来相当累,你最好停下来好好休息。

短语stop doing sth.表示“停止做某事”;stop to do sth.表示“停下来去做某事”。根据“You look quite tired.”可知下文是停下来去休息;You'd better+动词原形,表示“你最好做某事”;根据题意,故选A。

7.A

解析:A

【解析】

【详解】

句意:——Tom,我们8点将会去购物,对么?——是的,但是我可能会晚一点,所以不要等我。

考查情态动词词义辨析。A. may可能;B. should应该;C. mustn’t禁止。根据句意可知是可能会晚到。故选A。

8.B

解析:B

【解析】

【详解】

句意:你应该因为上学迟到向老师道歉。

本题考查动词短语。apology道歉,是名词;apologize道歉,是动词;about关于,for为了,on在……上面。apologize to sb for sth“因为某事向某人道歉”,位于情态动词should 后,用动词原形,故选B。

9.B

解析: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。

10.C

解析:C

【解析】

【详解】

句意:——我想知道是否这是Jim的眼镜。——它们不可能是他的,他不戴眼镜。

考查情态动词。A. might be可能是;B. could be有可能;C. can't be不可能,表示否定的推

测,语气很强。根据句意可知,空处是表示否定的推测,并且语气很强烈,故选C。11.C

解析:C

【解析】

【分析】

【详解】

句意:——这个读书报告很重要。你必须仔细地写。——但我现在必须交上它。

考查情态动词。must必须,表示说话人主观上的看法;have to不得不,必须,强调客观需要。第一句表示说话人认为对方必须认真写,是主观看法,第二句表示客观需要不得不现在上交,故选C。

12.A

解析:A

【解析】

【分析】

【详解】

句意:即使最优秀的学生也做不出这道题,所以它一定很难。

考查情态动词。must必须,一定;may可能;can能,会;need需要;根据句意理解可知,这里表达的是极其肯定的推测,表示“一定”,所以应该用must,故选A。

【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”,本题就是非常肯定的推测;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,表示可能性的推测,意为“可能,也许”;做题要稍加留意,要注意本身词义和推测词义的区别。

13.B

解析:B

【解析】

【分析】

【详解】

句意:——杨小姐,我能从图书馆借这些书吗?——对不起,你不能。这些书仅供英语俱乐部的会员借阅。

考查情态动词的用法。can“能,会”,情态动词;could是can的过去式。表示请求允许(即请求别人允许自己做某事)时,既可用 can也可用could,但这里的 could 并不表示过去,而是表示现在,只是比can的语气更委婉。若表示给予允许(即自己允许别人做某事),一般只用can/can’t。综上所述,故选B。

14.B

解析:B

【解析】

【分析】

【详解】

句意:——今天下午你可以和我一起去闲逛吗?——对不起,我不能。我必须为清洁日定计划。

考查情景交际。Sorry, I couldn’t对不起,我不能。前句的could表示一种委婉的语气,答语中的could表示过去,错;Sorry, I can’t 对不起,我不能;Sure, I can当然,我能。与后句矛盾,错;Sure, I could当然,我能。与后句矛盾,错。故选B。

15.C

解析:C

【解析】

【分析】

【详解】

句意:——妈妈,我必须和你出去吃饭吗?——不,你不必。亲爱的,你可以自由地做出你自己的决定。考查情态动词。A. shouldn’t不应该;B. mustn’t不允许;C. needn’t不必;

D. can’t不能。根据No, you , my dear. You’re free to make your own decision.可知此处为否定回答,must的含义是“必须、一定”,其否定形式mustn’t表示“禁止”的含义;在这里根据语境可知不是“禁止”的意思。对must开头的一般疑问句作否定回答,一般用needn’t或don’t have to,故答案选C。

16.B

解析:B

【解析】

【分析】

【详解】

句意:——我感到累了。——你不应该这么晚才睡觉。

考查情态动词。must必须、一定;shouldn’t不应该;should应该。根据上文I feel tired. 我感到累了。可知是建议“不应该”太晚睡觉,符合语境,故答案选B。

17.C

解析:C

【解析】

句意:每个人都应该对父母有礼貌。A. could可能; B. may也许; C. should应该;表示按理应当; D. can能够。根据句意故选C。

18.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。

19.D

解析:D

试题分析:句意:—互联网正使生活变得便利起来。—那是真的!几乎所有的事情都能够在网上完成。四个选项都是情态动词。A. must必须;would表示将要,将会;should应该;D.can能,强调可以。根据句意故选D。

考点:考查情态动词的用法。

20.D

解析:D

【解析】

【分析】

【详解】

句意:——我今天必须交报告吗?——不,你不必。

考查情态动词辨析。mustn’t禁止;can’t不能;shouldn’t不应该;don’t have to不必。对于must开头的一般疑问句,做否定回答,用needn’t或don’t have to,根据题意,故选D。

21.A

解析:A

【解析】

【分析】

【详解】

句意:我们班主任已经制定出一套班规来告诉我们在课堂上哪些必须做,哪些不能做。

考查情态动词,must必须,一定;will将,会;need必要;might可能。班规规定的纪律应该是必须遵守或者禁止做的。故选A。
