文档简介
课件103张PPT。If he weren’t addicted to QQ games,he would make greater progress in his studies.What would happen if he were not addicted to QQ game?The Subjunctive Mood虚拟语气在英语中随着说话人意图的不同，动词需用不同的形式，称为语气。英语语气有三种：语气(mood)是一种动词形式，用以表示说话者的意图或态度。②祈使语气：表示说话人对对方的请求、邀请、命令、警告或劝告等。 Please be careful. 请细心点。①陈述语气：表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。 There are two sides to every question. ③虚拟语气：表示动作或状态不是客观存在的事实，而是表示说话人的一种愿望、建议、命令、要求、有时是一种非真实的假设、料想，或是不可能实现的与事实相反的愿望。 If I were a bird, I could fly in the air.如果我是一只小鸟，我就能在空中飞行。May you succeed! 祝您成功！I wish you were more careful. 但愿你更细心些。例句观察：

Would you be so kind as to show me the way to the railway station.need "不必做"和"本不该做"?
didn't need to do表示： 过去不必做某事, 事实上也没做。.needn't have done表示： 过去不必做某事, 但事实上做了。John went to the station with the car to meet Mary, so she didn't 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 Mary, so she needn't 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，没有遇上John的车。)典型例题 There was plenty of time. She ___. A. mustn‘t have hurried B. couldn’t have hurried C. must not hurry D. needn't have hurried答案D。needn't have done. 意为"本不必"，即已经做了某事，而实际上不必要。mustn't have done 用法不正确，对过去发生的事情进行否定性推断应为couldn't have done, "不可能已经"。 must not do 不可以（用于一般现在时）D
例1 、If I were you, I to the cinema with her.(96)
A. went B. have been
C. had been D. would go【分析】 通过if从句中谓语动词“I were”可判断出，该句是与现在事实相反的虚拟条件句。主句用“would+动词原形”。故选答案D。D、试题详解例2 The doctor proposed that my brother his right hand.(97)
avoid to use B. should avoid to use
C. avoid using D. avoided using【分析】 该题有两个考点，一是propose后的宾语从句要用虚拟语气动词形式，二是avoid一词后要用动名词作宾语。故选C。【分析】 It is(high)time that…这一句型用虚拟语气动词形式用动词的过去式，表示“提醒”或“催促”等意。故选D。例3 It is time we .(98)
A. start B. to start
C. starting D. started例4 Had you not helped me with my English, I to pass the final examination.
A. might fail B. might have failed
C. shall fail D. would fail【分析】 当if从句中有were, should和had等词时，可以省略if， 同时把were, should, had放到主语前面形式倒装。从句中的had…not helped表明该句是与过去事实相反的假设，因此要选B。1. ____ for the free tickets, I would not have gone to the films so often.
A. If it is not B. Were it not
C. Had it not been D. If they have not
2. Our teacher insisted that we ____ in class.

The teacher suggested that we (should) clean the blackboard after class. 老师建议我们课后把黑板擦了。
He insisted that all of us should be there on time by any means. 他坚持要我们大家想尽办法按时去那儿。
虚拟语气在：在宾语从句中 虚拟语气在句型 “It is important (necessary, strange, natural) that .... ” 中，that 后面的从句中的谓语动词用： should + 动词原形
[练习]
It’s necessary that we should have a walk now. 我们有必要出去散散步。
It’s natural that she should do so. 她这样做是很自然的。
It’s important that we should take good care of the patient. 重要的是我们要照顾好病人。 虚拟语气在 在主语从句中虚拟语气二、省略 if 的条件从句
当从句中有 were, had 或 should 时，可省略if ，而把它们放在句首。
If I were to meet him tomorrow, I should ask him about it.
Were I to meet him tomorrow,…
If he should fail in the experiment this time, he would try again.
Should he fail in the experiment…
虚拟语气在 在条件从句中虚拟语气三、错综时间的条件句
即从句与主句的动作发生的时间不同。此时，需要按时间来确定虚拟形式。如：
If they had studied hard, they could do it easily now. 如果他们以前努力学习的话，现在干的就会容易些。
If he had not taken my advice, he wouldn't do it much better like this. 如果他不听取我的建议，他就不会干得这样好。 虚拟语气在复合句中的应用：判断以下句子是不是正确的虚拟语气：If we could finish our work earlier
we shall go to the cinema.2. The doctor suggests that she will not smoke.3. I wish that it is true.4. Had you put on more clothes, you would not catch a cold.shall 改成 shouldwill not 改成 ( should ) notis 改成 werewould not catch 改成 would not have caughtan Admission Notice of Beijing University高考重点1．一些常见的虚拟语气的句型或结构。 2．虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式。 3．主从句表示不同的时间概念、事实或假设情况， 从而交错成为复合虚拟语气。 4．条件句中的虚拟语气的表示愿望的虚拟形式。
上述四个要点往往在完形填空或者阅读理解里面存在，尤其是每年完形填空都至少有一道直接考这方面的知识的题目，而在阅读理解里，我们掌握上述四个重点对于我们理解文章的大意和作者态度很有帮助，了解哪些观点是作者假设的、虚拟的，哪些是真实的，这样对于我们回答关于作者态度观点题很有帮助。 Notes1.不是所有的条件句都用虚拟语气2.虚拟语气中常用were代替was3.虚拟语气的倒装语序4.错综时间条件句Blackboard DesignGrammar- The Subjunctive Mood(虚拟语气）

She ___. A. mustn‘t have hurried B. couldn’t have hurried C. must not hurry D. needn't have hurried答案D。needn't have done. 意为"本不必"，即已经做了某事，而实际上不必要。mustn't have done 用法不正确，对过去发生的事情进行否定性推断应为couldn't have done, "不可能已经"。 must not do 不可以（用于一般现在时）D
例1 、If I were you, I to the cinema with her.(96)
A. went B. have been
C. had been D. would go【分析】 通过if从句中谓语动词“I were”可判断出，该句是与现在事实相反的虚拟条件句。主句用“would+动词原形”。故选答案D。D、试题详解例2 The doctor proposed that my brother his right hand.(97)
avoid to use B. should avoid to use
C. avoid using D. avoided using【分析】 该题有两个考点，一是propose后的宾语从句要用虚拟语气动词形式，二是avoid一词后要用动名词作宾语。故选C。【分析】 It is(high)time that…这一句型用虚拟语气动词形式用动词的过去式，表示“提醒”或“催促”等意。故选D。例3 It is time we .(98)
A. start B. to start
C. starting D. started例4 Had you not helped me with my English, I to pass the final examination.
A. might fail B. might have failed
C. shall fail D. would fail【分析】 当if从句中有were, should和had等词时，可以省略if， 同时把were, should, had放到主语前面形式倒装。从句中的had…not helped表明该句是与过去事实相反的假设，因此要选B。1. ____ for the free tickets, I would not have gone to the films so often.
A. If it is not B. Were it not
C. Had it not been D. If they have not

If he should fail in the experiment this time, he would try again.
Should he fail in the experiment…
虚拟语气在 在条件从句中虚拟语气三、错综时间的条件句
即从句与主句的动作发生的时间不同。此时，需要按时间来确定虚拟形式。如：
If they had studied hard, they could do it easily now. 如果他们以前努力学习的话，现在干的就会容易些。
If he had not taken my advice, he wouldn't do it much better like this. 如果他不听取我的建议，他就不会干得这样好。 虚拟语气在复合句中的应用：判断以下句子是不是正确的虚拟语气：If we could finish our work earlier
we shall go to the cinema.2. The doctor suggests that she will not smoke.3. I wish that it is true.4. Had you put on more clothes, you would not catch a cold.shall 改成 shouldwill not 改成 ( should ) notis 改成 werewould not catch 改成 would not have caughtan Admission Notice of Beijing University高考重点1．一些常见的虚拟语气的句型或结构。 2．虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式。 3．主从句表示不同的时间概念、事实或假设情况， 从而交错成为复合虚拟语气。 4．条件句中的虚拟语气的表示愿望的虚拟形式。
上述四个要点往往在完形填空或者阅读理解里面存在，尤其是每年完形填空都至少有一道直接考这方面的知识的题目，而在阅读理解里，我们掌握上述四个重点对于我们理解文章的大意和作者态度很有帮助，了解哪些观点是作者假设的、虚拟的，哪些是真实的，这样对于我们回答关于作者态度观点题很有帮助。 Notes1.不是所有的条件句都用虚拟语气2.虚拟语气中常用were代替was3.虚拟语气的倒装语序4.错综时间条件句Blackboard DesignGrammar- The Subjunctive Mood(虚拟语气）
