关于虚拟语气的一些问题。

除了as if ,if 之外,还有什么可以来引导虚拟语气呢?

另外,个人比较不理解,为什么是"if i were you.","if she were deaf."呢?为什么不是was呢?

追加:请细致的介绍虚拟语气。

标准:
细致易懂者优先,其外例句多种多样者优先,原创次之。在以上三者难决雌雄之时,以回答时间先后决定。 优者追加20~50 以上

首先,要理解虚拟语气的定义:虚拟语气是一种不肯定的语气或者是假设的语气,比如if(如果,假如),as if(就像,只是像但实际上不是)。

其次,要分清楚虚拟语气的几种常见类型:
一. If引导的非真实条件句(注意if引导的可以实现的条件,称为真实条件句)

If从句 , 主句
(将来) 1.过去式(be只能用were) , would/should/could/might+V原
2.were to + V原 , would/should/could/might+V原
3.should+V原 , would/should/could/might+V原
If there should be no air, there would be no living things.

(现在)过去式(be只能用were) , would/should/could/might+V原
If I were a bird, I would fly everywhere.

(过去) had done , would/should/could/might+have done
If we had started earlier, we should not have missed the train.

(当然,有时候是主句在前,if从句在后,规则是一样的。)

二. 从句中的虚拟语气
1.表示愿望,建议, 命令,要求等的宾语从句中,要用 “ (should) +动词原形” ,这些词有:
wish, suggest, order, demand, propose, command, request, recommend, require, decide, insist, desire, urge,suggestion, proposal, plan, motion, re
