【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。

2、should作为情态动词,可以用在条件状语从句中,表示语气较强的假设,译作“万一”、“竟然”,这时也可将should置于从句之首,即将should放在主语前面,而省略从属连词if。例如：If you should fail to come, ask Mrs Chen to work in your place.（= Should you fail to come, ask Mrs Chen to work in your place.）
A．mayB．canC．mustD．ould

A．canB．needC．mustD．will
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。
中国学生的常见病句是：They...; they certainly have arrived.病句的句义是“他们当然已经到达了。”（这不是对过去的肯定推测，而是断定动作已经完成。）
11．According to a newly released regulation on online video services, no one _____ generate, release or spread fake news or information by using such technologies.
Somebody must have stolen the ring.肯定有人偷了这枚戒指. [该句所推断的偷窃动作发生在过去.]
The temperature must have dropped to below zero last night, because the water is frozen all over.昨夜的温度肯定降到零度以下，因为水都冻住了。

Shall的用法
Shall作为助动词，一般用于第一人称Ⅰ和We，表示一个将来的动作，构成将来时态。Shall后面接动词原形。例如：
如果“must + have +过去分词”句型与by now连用，还可以表示对现在完成的动作和状态的肯定推测，但实质上还是指所推测的过去的动作。例如：
They started early this morning; they must have arrived by now.他们今晨很早就出发了，现在肯定已经到了。
【点睛】
情态动词+ have done结构：
1.“must + have +过去分词”表示对过去发生的事情或状态进行推测，语气比较坚定，通常只用于肯定句。如：It must have rained last night,for the ground is wet.
2.“can / could + have +过去分词”表示对过去某种情况的怀疑或不确定。can和could一般用于否定句和疑问句，could的语气较can弱。如：He can't have finished the work so soon.
He oughtn't to / shouldn't have done that.他本来就不该做那件事.（可是做了）
6.“would＋have＋过去分词”表示对过去的某种情况进行猜测，或本来要做某事却因某种原因未做成，通常用来说明某一情况，但不像用should或ought to那样含有责备之意。如：
5.“should / ought to + have +过去分词”表示过去本该做某事但没做，其否定式表示过去不该做某事但做了，这种句式含有不满或责备之意，ought to的语气比should强一些。如：
You ought to / should have studied harder.你本应该更努力学习的.（但没有）
