1.英语动词有三种语气， 陈述语气，祈使语气和虚拟语气。2. 定义：用来表示说的话不是事实，或者是不可能发生的情况，而是一种愿望，建议，假设的语气叫虚拟语气。
1. 虚拟语气用以表示假定，想象，愿望等非事实的观念。2. 虚拟条件从句中的条件是假设的，因此主句的结论也只能是想象的，非事实的。3. 这些特点决定了它必须使用不同于真实句的动词形式。

5.表示要求，命令，建议的虚拟语气。
宾语从句。常见动词： 一个坚持，两个命令，三个建议，四个要求。即: 1. insist 2. rder, cmmand 3. advise, suggest, prpse 4. demand , require, request, desire 这些动词后面的宾语从句要使用虚拟语气。即从句中的动词 使用shuld + 动词原形，或者将shuld省略。

We suggested that Tm (shuld ) have a rest.
He insisted that I (shuld )be present.

以上动词相应的名词构成的名词性从句包括主语从句，表语从句和同位语从句也要使用虚拟语气。从句中的动词形式一样。 即：(shuld)＋V. rder, advice, suggestin, prpsal, demand, request, desire

9. 某些简单句的固定句型： Heaven help him! Gd bless yu! May yu succeed! Lng live the Peple’s Republic f China!
三： 虚拟语气假设条件句型注意点：
1.假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致，这种条件句叫做混合条件句。主句和从句的谓语动词要依照假设的时间而定。(“各归各” 的原则）If the weather had been finer, the crps wuld be grwing better.If yu had fllwed the teacher’s advice, yu wuldn’t be in the hspital.
2. 虚拟条件句倒装。 条件从句中有shuld， were， had三个助动词可以把if省略，并将这三个词提至句首。If I were yu, I wuld give it up. Were I yu, I wuld give it up.If it were nt fr yur advice, we culdn’t have gt ver the difficulties. Were it nt fr yur advice, we culdn’t have gt ver the difficulties.
If I had had time, I wuld have run rund the lake again.Had I had time, I wuld have run rund the lake again.If there shuld be a fld, what shuld we d?Shuld there be a fld, what shuld we d?
