情态动词练习

一、单项选择情态动词

1.It wasn’t right to me that such near neighbors not know one another. A.could C.should 【答案】C 【解析】 【详解】

考查情态动词。句意:对我来说,很不正常,如此近的邻居居然不认识。A. could可能,能够;B. would将;C. should竟然;D. might可能,也许。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\,住的这么近的邻居居然不认识。表示意外,所以答案选C。 【点睛】 should的用法

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.

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. )

3、should 作为情态动词,可以表示谦逊、客气、委婉之意,译为“可……”、“倒……”。例如:I should say that it would be better to try it again.

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?

5、should 作为情态动词,可以用来表示有较大可能实现的猜测、推论,通常译为“可能”、“总该……吧”,相当于 be expected to 。例如:They should be home by now, I think. 我想现在他们总该到家了吧。

6、should 作为情态动词,用在由 so that, for fear that, lest 引导的目的状语从句和 in case (that) 引导的条件状语从句中,有“能够”、“可能”、“会”之意。例如:They got up early so that they should (= could/ might) catch the first bus in time. 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。

本句中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,

B.would D.might

常常译为\竟会\、\居然\,住的这么近的邻居居然不认识。表示意外,所以答案选C。

2.Look! There are so many mistakes in your composition. You ________ have fixed full attention on it. A.can C.need 【答案】B 【解析】 【详解】

B.should D.might

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。

3.We’ll make the final decision on our scheme. ______ you change your mind, please inform us as soon as possible. A.Should 【答案】A 【解析】 【分析】 【详解】

考查虚拟语气。句意:我们将对我们的计划做最后决定。如果你改变主意,请尽快通知我们。根据语境,此处用虚拟语气,表示与将来相反,从句用should+动词原形,省略if,should提前,陈述句是:If you should change your mind……。故选A。 【点睛】 虚拟语气中的倒装

当虚拟条件句中含有 were,had,should时,可以将if省略,然后将 were,had,should,移至句首:

1)If he should fail, he would kill himself. →Should he fail, he would kill himself. 万一失败,他就会自杀。 2)If I were you, I would do it at once. →Were I you, I would do it at once. 假若我是你,我就会马上做。 要是我能做此事,我一定会做。

3)If he had seen you yesterday, he would have asked you about it. →Had he seen you yesterday, he would have asked you about it. 他昨天要是看到了你,他就会问你这事了。

该小题属于上述的第一种情况。should作为情态动词,有一种特殊的用法:在虚拟条件状

B.Were

C.Would

D.Had

语从句中表示与将来事实相反的虚拟语气,可以把should放在句首,即主语前,从而省略从属连词if。原来的表述为:If you should change your mind。故选A。

B.must D.shall

5.—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 【答案】D 【解析】
