例1.There be any difficulty about passing the road test since you have practised a lot in the driving school. A. mustn’t B. shan’t C. shouldn’t D. needn’t 答案:C [解析] 根据经验或惯例对某一情况进行推测.用should或ought to.常译成“按理应该- 或“可能会-- .shouldn’t是其否定形式. 例2.-Is John coming by train? -He should, but he not. He likes driving his car. A. must B. can C. need D. may 答案为D. [解析] come, go, leave, start等趋向动词的进行时表示将来时.所以答语是对这一将来动作做出的推断.may not“可能不,不一定 .根据he likes driving his car可以看出John可能乘火车来.也可能自己开车来.may not正好符合这一语境.must not“不准 ,cannot“不可能 ,need not“不必 . 例3.It is hard for me to imagine what I would be doing today if I in love, at the age of seven, with the Melinda Cox Library in my hometown. A. wouldn't have fallen B. had not fallen C. should fall D. were to fall 答案为B. [解析] 根据句意和I would be doing可以判断这是虚拟语气.at the age of seven 是表示过去的时间状语.if从句中的谓语要用had not fallen.表示对过去情况的假设.由于主句中的谓语表示对现在的虚拟.条件句中的谓语表示对过去情况的虚拟.增加了试题的难题.但是.使用排除法可以容易地做出该题:should fall 和were to fall都可以用于条件句中表示对将来的虚拟,wouldn't have fallen不用于条件句中.所以都不能作为答案.译文:如果我不在七岁时就迷恋上了我们家乡的Melinda Cox图书馆.我真不能想象我今天会做什么. 例4.You can't imagine that a well-behaved gentleman be so rude to a lady. A. might B. need C. should D. would 答案为C. [解析] should用于表示感情.意向等句中的that从句.表示“竟然--.居然-- 的惊讶.出乎意料.译文:你难以想象一位行为体面的绅士会对一位女士那么粗鲁. 例5.What would have happened , as far as up to the river bank? A. Bob had walked farther B. if Bob should walk farther C. had Bob walked farther D. if Bob walked farther 答案为C. [解析] 因为主句的谓语动词用了would have happened.所以从句的谓语动词要用过去完成时.在虚拟语气中.如果条件状语从句中的if省略.该句要倒装.译文:如果鲍勃走得远一点.走到岸边.会发生什么事呢? 例6.Mr. Bush is on time for everything. How it be that he was late for the opening ceremony? A. can B. should C. may D. must 答案为A. [解析] can表示可能性的推测.常用于疑问句或否定句中,may表“可能性常用于肯定句或否定句中,must常用于肯定句中表推测.“一定-- 的意思.注意:can not表示“不可能 .而may not表示“或许不--可能不-- .两者语气上有区别.译文:布什先生按时做好一切事.他来参加开幕式迟到了可能会是什么样的情景呢? 例7.My sister met him at the Grand Theatre yesterday afternoon, so he your lecture. A. couldn't have attended B. needn't have attended C. mustn't have attended D. shouldn't have attended 答案为A. [解析] “情态动词+不定式完成式有各自的含义.must have done表示对过去事情的肯定推测.多用于肯定句中,needn't have done表示过去本不必做的事情,shouldn't have done表示过去做了不该做的事情,can't have done表示对过去的否定性推测.意为“不可能 .所提供的情境My sister met him at the Grand 表示他不可能参加讲座. 例8.He hesitated for a moment before kicking the ball, otherwise he a goal. A. had scored B. scored C. would score D. would have scored 答案为D. [解析] 根据otherwise可以判断出要用虚拟语气.表示过去发生的事要用would have scored.译文:在踢球前他犹豫了一会儿.否则他就会射中球门. 例9.Oh, I'm not feeling well in the stomach. I so much fried chicken just now. A. shouldn't eat B. mustn't have eaten C. shouldn't have eaten D. mustn't eaten 答案为C. [解析] just now是表示过去的时间状语.情态动词在表示过去发生的事时.必须用“情态动词+have+过去分词的形式 .所以只能在选项B或C中确定答案.mustn't have eaten是一个错误选项.因为“mustn't+动词表示“禁止 .不表示判断或推测.译文:噢.我觉得胃不舒服.我刚才不应该吃那么多炸鸡. 例10.I was really anxious about you .You home without a word. A. mustn't leave B. shouldn't have left C. couldn't have left D. needn't leave 答案为B. [解析] should' t have done表示本来不应该做而做了.含责备意味.译文:我真为你着急.你不应该不说一句话就离开了家.另外注意mustn't+动词表示“禁止 . 第三节巩固练习 Direction: Beneath each of the following sentences there are four choices marked A. B. C and D.
