高三年级英语语法-虚拟语气全总结
虚拟语气在非真实条件句中①错综时间条件句:当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,被称为错综时间条件句,动词的形式要根据它表示的时间作出相应的调整。
如:If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首,变成倒装句式。
否定句时not留在原来位置不变。
如:If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会,我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come earlier, you would catch the bus.如果你来得早点,你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话,我们就不能登山去了。
③用介词代替条件状语从句常用的介词有with, without, but for。
如:What would you do with a million dollars? (=if you had a million dollars)如果你有100万元,你会做什么?We couldn‟t have finished the work ahead of time without your help. (=if we hadn‟t got your help) 没有你的帮助,我们不可能提前完成这项工作。
Without your help, we couldn‟t have finished the work ahead of time.= But for your help, …= If it had not been for your help, …= Had it not been for you help, …没有你的帮助,我们不可能提前完成这项工作。
④含蓄条件句有时在虚拟语气中并不总是出现if引导的条件句,而是通过其他手段来代替条件句。
如:I was ill that day. Otherwise, I would have taken part in the sports meeting. (副词)He telephoned to inform me of your birthday, or I would have known nothing about it. (连词)A man who stopped drinking water would be dead in about seven days. (定语从句)I might have given you more help, but I was too busy. (连词)Everything taken into consideration, they would have raised their output quickly. (独立主格结构) ⑤even if, even though也可用于虚拟语气,其形式与if 从句在虚拟语气中的形式相同。

(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。

英语语法 虚拟语气的知识点归纳
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。
