(完整版)英语虚拟语气语法归纳总结

(完整版)英语虚拟语气语法归纳总结英语中的虚拟语气是一种表示非事实或想象的语气,用来表达对现实情况的猜测、愿望、要求、建议、命令和反讽等。

虚拟语气主要通过动词的形式和句子的结构来表达。

一、虚拟语气的用法:1.表达建议、要求、命令、禁止:- 主语+动词原形+宾语(动词原形要用动词底形、如be);- 主语+动词原形+that从句(用于表达建议、命令、禁止,动词原形用“should + 动词原形”或用情态动词)。

例句:- It is important that he be present at the meeting.(建议)- I suggest that he should go to the doctor.(建议)- They insisted that he leave the room immediately.(命令)2.表达愿望、请求、要求:-主语+动词过去式;- 主语+would/could/might + 动词原形;- 主语+动词过去式+宾语+should + 动词原形。

例句:- I wish I could fly.(愿望)- I would appreciate it if you could help me.(请求)3.表示虚拟条件:- If条件从句中的谓语动词用过去完成时,主句用would/should/might/could + have + 过去分词;- If条件从句中的谓语动词用过去时,主句用would/should/could + 动词原形。

例句:- If I had known his phone number, I would have called him.(虚拟条件)- If you had listened to me, we could have finished the project earlier.(虚拟条件)4.表达建议、要求、祝愿:- If only内部称述 + 主语 + 过去式。

英语语法虚拟语气的知识点归纳一、虚拟条件句(一)含有if条件句的主从句的虚拟语气总结:1. If 条件句中谓语动词的虚拟结构是在原来陈述语气所用时态的基础上倒退一个时态(对将来虚拟的were to do/should do例外)2. 主句要借助于情态动词的过去式,后跟动词原形(现在或将来)或have done(过去);if条件句中只出现一个情态动词,即对将来虚拟的should.3.做此类题目时一定要分清是从句还是主句谓语动词的虚拟,还要把握好时态。

注意:1. 在虚拟条件从句中,动词“be”的过去时态一律用”were”,不用was。

2. 在虚拟条件状语中如果有were, should, had这三个词中任何一个,可省略if,把这三个词提到主语之前, 变成:were/should/had +主语+剩余成分。

3.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Weren‘t I to do。

4.在表示与将来事实相反的条件句中,只能用should,而不能用would,could和might 等。

5.主句中的should通常用于第一人称,would,could以及might 可以用于各种人称eg :①If 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。

②I wish I could pass the examination.我希望我能通过考试。

在虚拟条件句中,对于与将来事实相反的情形,请注意以下几点:(1)条件从句表示的内容与将来事实相反,实为对将来情况的推测,用过去时表示虚拟;(2)条件从句谓语除用过去式外,有时也用“should+动词原形(表示可能性极小,常译为“万一”)”或“were to+动词原形(表示与将来事实相反的假设)”;(3)条件从句使用“should+动词原形”这样的谓语形式时,主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气形式外,也可用直陈语气或祈使语气。

虚拟语气知识点简述

虚拟语气知识点简述

虚拟语气知识点简述1、含义:用来表示说的话并不是事实,而是一种愿望或者是一种与事实相反的假设。

通常结构为if+从句,主句。

2、规则变化:表示与现在事实相反。

从句:if+主语+动词的过去式/was,were主句:主语+should,would,might,could+动词原形表示与过去事实相反从句:if+主语+had done(过去分词)主句:主语+should,would,might,could+have done表示与将来事实相反从句:if +主语+动词过去式/were to+动词原形/should+动词原形主句:主语+should,would,might,could+动词原形省略if的虚拟语气,从句中有were,had,should等词语,省略if,将were,had,should提到句首。

3、混合虚拟条件句,不同时间的虚拟,各自遵守各自的规则。

If you had followed the doctor’s advice, you would be quite all right now.从句对过去虚拟,所以用had done, 主句对现在虚拟,所以用would+动词原形4、表示坚持,命令,建议或暗示的含义时,使用should+动词原形。

should可以省略。

此类经常考,常见单词有insist, suggest, require, demand 等。

譬如:His smile suggested that he was satisfied with our work.他的笑容暗示他对我们的工作很满意。

该类句式也可发生变化,甚至是词性变为名词,但意思属该类,也需要用should+动词原形的结构。

Eg: It is important that we (should) think before we decide.Our suggestion is that the meeting (should) be put off.5、特殊用法:看标志词语。

虚拟语气定义:表示说话人所说的不是事实,而是一种假设、愿望、怀疑或推测。

应用:错综时间条件句:A.非真实性条件句:if省略句:把were,had,should提到句首,变为倒装句式。

(Attention:否定形式)含蓄条件句:表示隐含条件,结构与if同。

(without, but for, or/otherwise)a. wish后接宾语从句,表示不可能实现的愿望。

宾语从句 b. 用于表示建议、命令、要求等动词后宾语从句。

B.名词性从句: c. would rather主语从句:It is/was+形容词/过去分词+ that从句。

表语从句&同位语从句:在suggestion, proposal, order, plan, idea,request, advice等名词后的表语从句和同位语从句中要用虚拟语气,C.as if/as though引导的从句:常与seem/look/appear等动词连用,表示“看起来似乎……”;以及if only表示“要是……该多好呀”。

(结构同wish)D.定语从句和状语从句:定语从句:It is (high) time (that)…句型中。

目的状语从句:in case, for fear that, in order that, so that等引导目的状语从句。

考点一 虚拟语气在非真实性条件句的运用要点归纳:真实条件句:假设的情况是有可能发生,谓语要用陈述语气。

假设的情况是过去或现在都不存在的,或将来不大可能发生。

e. g. If it doesn’t rain tomorrow, we will go to the park.If he had seen you yesterday, he would have asked you about it.虚拟语气结构列表如下:e.g. If he were here, everything would be all right.从句(条件句) 主句(结果句) 与现在事实相反的假设If +主语+动词过去式(were ) 主语+ should/would/could/might +动词原形 与过去事实相反的假设 If +主语+ had +过去分词主语+ should/would/could/might + have +过去分词与将来事实相反的假设 1. If +主语+动词过去式 2. If +主语+ were to +动词原形 3. If +主语+ should +动词原形主语+ should/would/could/might +动词原形If her mother had taken the doctor’s advice, she would/might have got well earlier.If it were to rain tomorrow, the match would be canceled.1、错综时间条件句有时条件从句的动作和主句动作发生的时间不一致,这时需根据意思采用表示不同时间的动词形式来进行调整。

If she had taken the doctor’s advice, she might still be alive.If I were you, I would have accepted their terms.2、if省略句,采用局部倒装语序。

把had /should/were等动词(不包括行为动词)移到从句的句首。

If I were at school again, I would study harder.Were I at school again, I would study harder.If it should rain tomorrow, we would not go climbing.Should it rain tomorrow, we would not go climbing.If you had come earlier, you would have caught the bus.Had you come earlier, you would have caught the bus.3、含蓄条件句:有时候假设的情况并不用条件从句表示出来,而是通过其他手段来表示。

(结构同wish)e.g. He talks as if he knew where she was.He talks about Rome as if he had been there before.It looks as if it might snow.e.g. If only the player had had more courage!If only Daisy would go with me!【小试牛刀】1.——It was John who broke the window.——Why are you talking to me as if I __________ (do) it?2.He speaks Chinese so fluently as if he __________ (be) a Chinese.3.Looking round the town, he left as though he __________ (be) away for ages.4.Look at the trouble I am in!
