1、高一英语暑假专题虚拟语气冀教版【本讲教育信息】一. 教学内容：暑假专题虚拟语气1虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气在条件句中应用比拟多。2条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。1. 真实条件句用于陈述语气，假设的情况有可能发生。各种结构参见下表：句型条件从句主句一般现在时shall/will + 动词原形祈使句情态动词一般现在时 例如：If he comes, he will bring his violin. 如果他来，会带小提琴来的。典型例题The

2、 volleyball match will be put off if it _.A. will rain B. rains C. rained D. is rained答案B。真实条件句主句为将来时，从句用一般现在时。注意：1在真实条件句中，主句不能用be going to表示将来，该用shall, will.错 If you leave now, you are never going to regret it.对 If you leave now, you will never regret it.2表示真理时，主句谓语动词不用shall will +动词原形，而直接用一般现在时的动词

3、形式。2. 非真实条件句 1虚拟语气可以表示过去，现在和将来的情况，时态的根本特点是时态往后推移。a. 与现在事实相反的假设条件从句主句一般过去时be用wereshouldwould等 +动词原形例如：If they were here, they would help you. 如果他们在这儿，会帮助你的。含义：They are not here, they cant help you.b. 与过去事实相反的假设条件从句主句过去完成时shouldwould等+ have+ 过去分词 例如：If he had come yesterday, I should / would have told

4、 him about it.如果他昨天来的话，我会把这件事告诉他的。 含义：He did not come yesterday, so I did not tell him about it.c. 表示对将来不大可能发生的事情的假想条件从句主句一般过去时should/would等 + 动词原形were+ 不定式should+ 动词原形 例如：If you succeeded, everything would be all right. 如果你将来成功了，一切都会好的。 If you should succeed, everything would be all right.If you we

5、re to succeed, everything would be all right.含义：You are not likely to succeed, everything will be what it is now.3. 混合条件句 有时，主句与从句的动作发生在不同的时间，主句从句谓语动词的虚拟语气形式因时间不同而不同，这种条件句叫做混合条件句。例如：If you had asked him yesterday, you would know what to do now. 如果你昨天问过他，今天就知道做什么了。从句与过去事实相反，主句与现在事实相反。If it had rained

6、 last night过去, it would be very cold today现在.如果昨晚下过雨，今天就会很冷了。4. 虚拟条件句的倒装 虚拟条件句的从句局部含有were, should或had时, 可省略if，再把were, should或had 移到从句的句首，实行倒装。例如：Were they here now, they could help us. =If they were here now, they could help us.他们现在在的话，就会帮助我们了。Had you come earlier, you would have met him. =If you ha

7、d come earlier, you would have met him.你来得早一点，就碰到他了。Should it rain, the crops would be saved. =Were it to rain, the crops would be saved.假设下雨，庄稼就有救了。注意：在虚拟语气的从句中，动词“be的过去时态一律用“were，不用was，即在从句中be用were代替。例如：If I were you, I would go to look for him. 如果我是你，就会去找他。If he were here, everything would be all

8、 right. 如果他在这儿，一切都会好的。典型例题_ to do the work, I should do it some other day.A. If were I B. I wereC. Were ID. Was I 答案C。在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do, 而不能说 Werent I to do。5. 特殊的虚拟语气词should 1在主语从句

9、中的应用It is demanded / necessary / a pity + that等结构的主语从句，谓语动词用should 加动词原形，should 可省略。It is 可用的词有三类thatshoulddosuggested, ordered, required, proposed, demanded, requested, insisted等important, necessary, natural, imperative, strange等a pity, a shame, no wonder等2在宾语从句中的应用在表示命令、建议、要求等一类动词后面的从句中，像order, su

10、ggest, propose, require, demand, request, insist, command, insist + should do等。例如：I suggest that we should hold a meeting next week. 我建议下周召开个会议。 He insisted that he should be sent there.他要求被派到那儿去。 注意：如suggest, insist不表示“建议或“坚持要某人做某事时，即它们用于其本意“暗示、说明、“坚持认为时，宾语从句用陈述语气。 判断改错：错You pale face suggests that

11、 youshouldbe ill. 对Your pale face suggests that you are ill. 错I insisted that youshouldbe wrong. 对I insisted that you were wrong.3在表语从句，同位语从句中的应用suggestion, proposal, idea, plan, order, advice等名词后面的表语从句、同位语从句中要用虚拟语气，即should+动词原形。例如：My idea is that weshouldget more people to attend the conference.我的想

12、法是让更多的人来参加会议。I make a proposal that weshouldhold a meeting next week.我提了个建议，下周我们开个会。6. wish的用法 1wish后面的从句，表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为：主句从句从句动作先于主句动作be的过去式为 were现在时过去时从句动作与主句动作同时发生had + 过去分词过去时过去完成时将来不大可能实现的愿望将来时would/could +动词原形例如：I wish I were as tall as you.我希望和你一样高。 He wished he hadnt s

13、aid that. 他希望他没讲过那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。2wish to do；wish sb / sth to do。例如： I wish to see the manager. = I want to see the manager. 我希望见一见经理。 I wish the manager to be informed at once. = I want the manager to be informed at once.我希望经理能马上得到消息。7. 比拟if only与only if only if表示“只有

14、；if only那么表示“如果就好了。If only也可用于陈述语气。例如：I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。If only the alarm clock had rung.当时闹钟响就好了。If only he comes early.但愿他早点回来。8. It is (high) time thatIt is (high time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。例如：It is time that the children went to bed. 孩子们该

15、睡觉了。It is high time that the children should go to bed.9. need“不必做和“本不必做didnt need to do表示过去不必做某事, 事实上也没做。neednt have done表示过去不必做某事, 但事实上做了。例如：John went to the station with the car to meet Mary, so she didnt need to walk back home. 约翰开车去车站接玛丽，所以她不必步行回家了。 John went to the station with the car to meet

16、 Mary, so she neednt have walked back home. 约翰开车去车站接玛丽，所以她本不必步行回家了。 Mary步行回家了，没有遇上John的车。典型例题 There was plenty of time. She _. A. mustnt have hurried B. couldnt have hurriedC. must not hurry D. neednt have hurried 答案D。neednt have done. 意为“本不必，即已经做了某事，而实际上不必要。mustnt have done 用法不正确，对过去发生的事情进行否认性推断应为c

17、ouldnt have done, “不可能已经。must not do 不可以用于一般现在时。【模拟试题】答题时间：60分钟1.
