【英语】情态动词练习题含答案及解析一、单项选择情态动词1．—Can I pay the bill by check?—Sorry，sir．But it is the management rules of our hotel that payment _____ be made in cash．A．shall B．needC．will D．can【答案】A【解析】【详解】考察情态动词用法。

句意：——我能用支票付账吗?——对不起,先生。

但这是我们酒店的管理规定,支付要用现金。

shall可以表示命令，警告，强制，或者指规则和法律要求做的事情。

本题正是考察了shall表示按照规则和法律要求做的事情。

故A正确。

2．You _____ be right but I’m going back to check anyway.A．should B．must C．need D．might【答案】D【解析】【详解】考查情态动词。

句意：你或许是对的，但我还是要回去核对一下。

A. should应该；B. must 一定，必须；C. need需要；D. might或许。

本题主要考查情态动词表示推测的用法，由I’m going back to check anyway可知，我对此不确定。

由此可知，D项符合题意。

故选D项。

【点睛】can / could用于表推测的用法(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。

两者没有时间上的差别，只是could 比 can 更委婉，更不确定。

(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接 be doing 结构；对过去情况作推测，后接动词完成式。

二、 may / might用于表推测的用法表示推测，两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小。

英语情态动词练习题20篇一、单项选择情态动词1．—It’s so hot and uncomfortable here! Why are your windows still closed?—Oh, I’m not to blame. They ________ open.A．XXX’t【答案】C【解析】【详解】考查情态动词辨析。

句意：---这里又热又不舒服！你的窗户怎么还关着？---哦，不该责备我啊。

窗户打不开了。

XXX not意为“不可,不应”；mustn’t=must not意为“不要”；XXX not 意为“不会，不愿意”。

XXX not意为“不会,不能”，will在这里表示能力、功能。

例如：XXX.这个礼堂能容纳一千人。

这句话意思是“这扇窗不能打开”，故选C项。

B．XXX’t2．—________ the woman with the baby come over? We have a seat here.—Thank you, XXX I do have my seat here. But my baby likes to look out of the window.A．WouldC．Must【答案】A【解析】【详解】考查情态动词。

句意：——那位抱小孩的女士，要不来这边吧?这儿有个坐位。

——谢谢，实践上我有坐位的，只是我的孩子喜爱看窗外。

XXX表示婉转的恳求，征求对方的看法，XXX提问一般只用于第一人称，我们常说Shall I.或者XXX；may表示恳求对方允许。

应选A。

【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 XXX.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：XXX she would have to ask someone for help.她当时想，她得找个人帮忙。

“may”表示可能，“must”表示必须，不符合题意。

2.We_____play games in the classroom.A.canB.couldC.can'tD.couldn't答案：C。

在教室里不能玩游戏，“can't”表示不能。

句意：我仍然难以想象这样聪明的孩子竟然犯这样愚蠢的错误。

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，常常译为"竟会"、"居然"，这么聪明的孩子竟然犯这样愚蠢的错误。

表示意外，shall表示允诺，命令等，must 表示必须，can表示能力及可能性。

句意：虽然这并不是这次旅行的目的，但我得到了一些新的领悟，那些领悟在我的日常生活中是本不可能发生的。

此处考查虚拟语气，“我得到新的领悟”发生在过去，故此处是与过去事实相反，应用could/might/would/need/should+have done，“本不可能发生”是could never have happened，故选B项。

【点睛】本题考查“情态动词+have done”的虚拟语气，其常用表达有：could have done本能做某事而未做couldn’t have done不可能做了某事should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了need have done本需要做某事而未做needn’t have done本不必要做某事而做了3．—I don’t really like Janes.

考查祈使句。

take携带，根据所给空后面的when you go out可知，应该用的是祈使句，祈使句肯定形式的构成：动词原形放在句首，故选B。

2．______ talk in the library.A．Don’t B．Not C．Not to A解析：A【解析】【详解】句意：在图书馆不要说话。

此处是祈使句的否定形式，因此在动词原形前加don’t，故为Don’t+动词原形。

故选A。

3．Mike, __________ make any noise, your father is sleeping.A．not B．don't C．won't D．can't B解析：B【解析】【详解】句意：麦克，不要吵闹，你父亲正在睡觉。

考查祈使句。

A. not 不，没有；B. don’t 不，没有；C. won’t 将不会；D. can’t 不能，不会。

A 选项为否定词；B选项为助动词，后面要接动词；C选项为助动词，将来时表将来；D选项为情态动词，表否定推测。

根据否定祈使句用法，应用助动词don’t + 动词原形结构。

A、C、D均不符合，故应选B。

4．Please _____ look outside. Look at the black board.A．not B．don’t C．aren’t D．can’t B解析：B【解析】【详解】句意：请不要往外面看，看黑板。
