英语-情态动词练习题
情态动词的正确使用
•1 must 的主要用法
must 可以表示义务和推测,当它表示推
测时,其否定形式为can’t∕can not, 而must not, mustn’t 表示“一定不要,不允许”。
B
The students smoke in the library.
A can’t
B mustn’t
C mayn’t
D don’t have to
•2 need and dare 的主要用法
need 和dare 既可以与主语颠倒构成疑问句,在后面加not构成否定句,也可以像实意词一样用助动词构成疑问句和否定句。
在疑问句和否定句中,dare 和need 常作情态动词。
B
Nobody tell the old man that his son died in the war.
A dares
B dare
C dare to
D doesn’t dare
•3 情态动词与动词的完成形式搭配
•1)must have done 表示对过去事件的推测,用于肯定句中。
否定句和疑问句中需用can’t have done.
D
You her in her office last Friday; she’s been out of town for two weeks.
•A needn’t have seen B must have seen •C might have seen D can’t have seen
•2) should∕ought to +have done表示过去应该发生而事实上没有发生的事情,意为“本应该…”。
它的否定形式为should not ∕ought not to+ have done, 意为“本不该”,表示对过去不该发生而发生的事情的责备或惊讶。
The careless man received a ticket for speeding. He have driven so fast.
C
• A can’t B wouldn’t
• C shouldn’t D mustn’t
•3) might∕could+ have done 表示谈论过
去的某种可能性,可能发生而没有发生,
意为“本来可以…本来能够…”。
D
•Some women a good salary in a job instead of staying home, but they decided not to work for the sake of the family.
•A must take B should have made
•C would make D could have made
•4) may have done 表示过去某种可能性,
而这种可能性现在还存在,意为“或许已经”。
•Research findings show we spend about two hours dreaming every night, no matter what we during the day.
C
•A should have done B would have done •C may have done D must have done
•5) needn’t have done 表示做了不必做的事情,意为“其实不必,没有必要…”,有时候可以用didn’t have to do来表达。
•It was very kind of you to do the washing-
D
up, but you it.
•A mustn’t have done
•B wouldn’t have done
•C mightn’t have done
•D didn’t have to
•6) would+ have done 表示本来可以做的事情,通常用于虚拟语气。

【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.)

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。
