(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
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。

英语语法：虚拟语气
虚拟语气用法详解一、条件句中的虚拟语气1. 条件句中虚拟语气的形式从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。
条件句中的虚拟语气根据不同的时间有三种不同的形式。
2.条件句中的虚拟语气的举例(1) 将来时的条件句中的虚拟语气。
如：If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分利用他的时间了。
If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。
(2) 现在时的条件句中的虚拟语气。
如：If he were free, he would help us. 要是他有空的话，它会帮助我们的。
If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。
(3)过去时的条件句中的虚拟语气。
如：If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。
If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。
3. 运用条件句中的虚拟语气时，须注意的几个问题(1)当从句的主语为第三人称单数时，谓语动词若是系动词be时，可用was 代替were。
但在倒装虚拟结构及if I were you, as it were 中，只能用were。
如：Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。
If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。
