情态动词练习题含答案及解析

【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。

高考情态动词练习题及答案详解一、单项选择情态动词1．Look! There are so many mistakes in your composition. You ________ have fixed full attention on it.A．can B．shouldC．need D．might【答案】B【解析】【详解】考查情态动词。

句意：看！你的作文里有那么多的错误。

你本应该把所有的注意力都集中在它上面的。

表示“本应该做但实际上没有做”应该用should have done结构，can have done 表示可能；need表示需要；might have done表示可能做过某事；故选B。

2．—I don’t really like Janes. Why did you invite him?—Don’t worry. He come. He said he was’t certain what his plans were.A．must not B．need not C．would not D．might not【答案】D【解析】考察情态动词，题干中的h e wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。

3．-- Did Jim come?-- I don’t know. He _______ while I was out.A．might have come B．might comeC．must have come D．should have come【答案】A【解析】【详解】考查情态动词推测用法。

句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。

根据前文I don’t know.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。

对过去情况的推测为情态动词+have done，must have done 一定做了某事，should have done 应该来过，不符合，故选A。

考查情态动词。

may not可能不；needn’t不需要；mustn’t禁止；shouldn’t不应该。

根据“No, according to the law, they...”可知，根据法律，他们禁止骑电动自行车上学。

故选C。

她讨厌那种颜色。

考查情态动词。

故选A。

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.
