虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，虚拟语气所表示的含义不是客观存在的事实。 If I were you, I'd take them away. 如果我是你的话，我就会带走他们。 If I had met Li Hua, I could had told him...
虚拟语气的用法归纳
虚拟语气的内收容重要有三大模块，第一模块就是触及到条件从句部分的内收容。这一部分的虚拟语气重要表示在三个方面：根底用法，各自为政，以及含蓄之美。
虚拟语气的根底用法是什么
| 条件从句的谓语动词模式 | 主句谓语动词模式 | |
| 与以前事实相反的假定 | had done | would/could/might/shouldhave done |
| 与现在事实相反的假定 | did(was→were) | would/could/might/shoulddo |
| 与将来事实相反的假定 | did(was→were); should do;were to do | would/could/might/shoulddo |
凡是，在上面表格里回响反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时辰是一致的，假如两者时辰不一致，此时就是同化型虚拟语气。同化型虚拟语气的行使要求“各自为政”，即从句和主句依照各自假定的时辰不同，采纳上面表格中对应的的谓语动词模式。
虚拟语气用法有哪些
虚拟语气在条件从句的用法
条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。
假如假定的情况是有可能发生的，就是真实条件句，谓语要用述说语气。如 If it doesn’t rain tomorrow, we will go to the park.
假如假定的情况是以前或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如 If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气.
错综时辰条件句
有时条件从句的动作和主句动作发生的时辰不一致，这时必要依照意思采纳暗示不同时辰的动词模式来进行调剂。
If she had taken the doctor’s advice, she might still be alive.
If I were you, I would have accepted their terms.
含蓄条件句
1.有时辰假定的情况并不用条件从句暗示出来，而是通过介词短语来暗示。
如 Without air(If there were no air), there would be no living things.
But for your help (If it hadn’t been for your help), I couldn’t have done it.
2. 假定的条件通过上下文暗示出来。
I would go abroad for further study but that I am poor.
I was ill that day. Otherwise I would have taken part in the party.
虚拟语气在名词性从句中的应用
“wish+宾语从句”暗示不成能实现的愿望，汉语可译为“惋惜……、悔不该……、进展……”。暗示现在不可实现的愿望，从句的谓语动词用以前式；
暗示将来不成能实现的愿望用“would/could+动词实情”；
暗示以前不成能实现的愿望时用“had+以前分词”。如：
I wish I were better-looking. 假如我长得再标致些就行了。
I wish I had met the film star just now. 我假如刚才碰着那位影戏明星该多好啊！
I wish I would be a solider. 我想当一名甲士。
虚拟语气在状语从句中的应用
1. if only的条件状语从句中的虚拟语气
if only 与 I wish一样，也用于暗示与事实相反的愿望，后来所接虚拟语气的时态与 wish 后所接时态的情况不异。如：
If only the player had had more courage! 这位选手再多有一些勇气就行了。
If only Daisy would go with me! 黛茜假如愿意和我一起往就行了!
