七年级英语情态动词准确使用练习题20题(带答案)1. In the school library, you ______ keep quiet.A. canB. couldC. mayD. must答案解析:D。

本题考查情态动词的用法。

can表示能力,“能够”;could是can的过去式,也可用于现在表示更委婉的请求;may表示许可或可能性,“可以,也许”。

在图书馆里需要保持安静是一种规定,must表示“必须”,所以这里应该选D。

2. - ______ I borrow your pen? - Sure.A. CanB. CouldC. MayD. Might答案解析:A。

这里是询问是否可以借笔,can表示请求许可,常用于口语中,比较直接。

could也可表示请求许可,但比can更委婉,常用于一般疑问句中,但在回答中通常用can。

may表示许可时,比较正式,这里是比较随意的场景,所以不选C。

might是may的过去式,也表示可能性,在这里不合适,所以选A。

3. He ______ run very fast when he was young.A. canB. couldC. mayD. might答案解析:B。

句中提到“when he was young”是过去的时间,can 的过去式是could,表示过去的能力,他年轻时能跑得很快,所以选B。

A选项can表示现在的能力;C选项may表示许可或可能性,与题意不符;D选项m ight表示可能性,在这里不表示能力,所以不选。

4. - ______ it be true? - I'm not sure.A. CanB. CouldC. MayD. Might答案解析:A。

这里是对事情真实性的一种推测,can用于疑问句中表示推测,“可能”,通常用于否定句和疑问句中。

could也可用于表示推测,但这里没有必要用过去式。

may和might表示可能性时,一般不用于疑问句的这种推测,所以选A。

高考英语情态动词练习题50题带答案1.You stay at home if it rains tomorrow.A.mustB.shouldC.mayD.have to答案解析:C。

“may”表示“可能,可以”,符合语境。

“must”表示“必须”,语气过于强硬;“should”表示“应该”,不太符合该语境;“have to”表示“不得不”,通常是客观条件所迫,而此处只是一种可能性,所以选C。

2.He be very tired after such a long journey.A.mustB.shouldC.canD.need答案解析:A。

“must”在这里表示肯定的推测,“长途旅行后他一定很累”。

“should”表示“应该”;“can”表示“能够”;“need”表示“需要”,均不符合语境,所以选A。

3.We go to the park if the weather is fine.A.canB.mayC.mustD.need答案解析:B。

“may”表示“可能”,天气好的话我们可能去公园,比较符合常理。

“can”表示“能够”;“must”表示“必须”;“need”表示“需要”,这三个选项都不太符合语境,所以选B。

4.She know the answer,but she's not sure.A.mustB.mayC.shouldD.can答案解析:B。

“may”表示“可能”,她可能知道答案但不确定。

“must”表示肯定的推测,与“not sure”矛盾;“should”表示“应该”;“can”表示“能够”,均不符合语境,所以选B。

5.You finish your homework before you watch TV.A.mustB.shouldC.canD.may答案解析:A。

“must”表示“必须”,先完成作业才能看电视。

“should”表示“应该”,语气不如“must”强烈;“can”表示“能够”;“may”表示“可以”,这三个选项都不符合语境,所以选A。

—Thank you, sir. Actually I do have my seat here. But my baby likes to look out of the window.
考点:考查情态动词用法
点评:考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;needn’t have done本没有必要做某事;注意没有mustn’t have done的形式。
7、should作为情态动词,可以用于下列虚拟语气句中:
(1)用在表示与将来事实相反的条件状语从句中,构成“ If …… should(do sth)……, …… would/ could/ might(do sth.)…… ”句式。
(2)用在suggest(propose), arrange, plan, decide, advise, order, demand, request, desire, insist等表示“建议”、“要求”、“命令”、“决定”、“安排”、“计划”、“主张”的动词后面接的宾语从句中。这里的should也可以省略。
【点睛】

1、should作为情态动词,通常用来表示现在或将来的责任或义务,译作“应该”、“应当”,这时它可以和ought to, be supposed to互换使用.例如:You should(= ought to)tell your mother about it at once.
A.couldB.would
C.shouldD.might
【答案】C
【解析】
【详解】

2.Tom, you _____ leave all your clothes on the floor like this!
A.wouldn’tB.mustn’tC.needn’tD.may not

【详解】
考查情态动词辨析。句意:汤姆,你不要把所有的衣服都这样扔在地板上! A. wouldn’t不会;B. mustn’t禁止;C. needn’t不需要;D. may not不可以。本句为祈使句,所以mustn’t “禁止”符合句意。故选B项。

【答案】A

【答案】C
【解析】
【详解】
考查情态动词辨析。句意:他是个脾气不好的家伙,但当他希望自己有魅力的时候,他可以变得相当可爱。此处表示“能、可以”,故C项正确。
【点睛】
would的用法
1.would最常见的用法是:相对于一个过去时间点的后来“将要”做什么,比如:He said he would meet me at the station.他说他会在车站接我的。这句中的would meet是相对于said(过去说)之后要做的事情。又如:She thought she would have to ask someone for help.她当时想,她得找个人帮忙。
10.The weather turned out to be fine. I _____________ the trouble to carry the umbrella with me.
A.should have takenB.must have taken
C.couldn't have takenD.needn't have taken

【答案】A

3.I love the weekend, because I ________ get up early on Saturdays and Sundays.
A.mustn’tB.needn’t

4、should作为情态动词,可以用来表示意外、惊喜或者在说话人看来是不可思议的.尤其在以why, who, how等开头的修辞疑问句或某些感叹句中常常译为“竟会”、“居然”。例如:How should I know it ?我怎么会知道这件事?
【详解】
考查部分倒装和情态动词。句意:这位教授警告学生们,在他的课堂上,决不应该使用手机。on no account意为“决不”,否定词放在句首,句子使用部分倒装,排除B、D项;这里表示应该,故选A。
