虚拟语气的定义：虚拟语气表示说话人的某种愿望、假设、怀疑、猜测和建议等，表示的是纯属假设或实现的可能性不大的情况。虚拟语气是由句中的谓语的特殊形式表现出来的。
虚拟语气的类型：虚拟语气从句型结构上可以划分为四类，分别是条件句中的虚拟语气，名词性从句中的虚拟语气和定语从句中的虚拟语气以及特殊结构和句型的虚拟语气。
（一）虚拟语气用于状语从句
If 引导的条件状语从句和even if /even though引导的让步状语从句，当从句表示不能实现或实现的可能性很小的时候，从句需要使用虚拟语气。用法如下：
虚拟语气 条件从句中的谓语动词 主句中的谓语动词
与现在的事实相反 一般过去时（be用were） would/should/could/might+动词原形
与过去的事实相反 had+ 过去分词 would/should/could/might+ have+过去分词
与将来的事实相反 一般过去时（be用were）should + 动词原形were to+ 动词原形 would/should/could/might+动词原形
If there _______ (be) no music, the world would be very dull.
If I _______(be) not busy, I will go to the party with you.
If I had known that you were coming, I ______________(pick) you up at the airport。

B 表示命令、建议、要求的词引导的名词性从句
表示命令、建议、要求的词“一，二，四，四”（insist,order, command, demand, desire, request, require, propose, suggest, advice, recommend）
从句谓语动词要用虚拟语气，结构是“(should)+动词原形”。
注意：insist作“坚持说，坚持认为”，suggest作“暗示，表明”讲时，宾语从句不用虚拟语气。
