高考英语情态动词及其解题技巧及练习题(含答案)

高考英语情态动词及其解题技巧及练习题(含答案) 一、单项选择情态动词 1.It_____ have been Tom that parked the car here, as he is the only one with a car. A.may B.can C.must D.should 【答案】C 【解析】 【详解】 考查情态动词表猜测的用法。句意:一定是汤姆把车停在这儿的,因为他是唯一有车的人。A. may可能;B. can可能;C. must一定;D. should应该。由as he is the only one with a car.可知一定是他把车停在这里的,非常有把握的肯定推测,故选C。 2.We’ll make the final decision on our scheme. ______ you change your mind, please inform us as soon as possible. A.Should B.Were C.Would D.Had 【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。
