一、英语虚拟语气语法
第一类
虚拟语气在条件句中的用法：
条件句有真实条件句和虚拟条件句两种。真实条件句所表示的假设是有可能发生的，此时主句不用虚拟语气；而虚拟条件句则表示一种假想，与事实相反或不大可能会发生，此时用虚拟语气。
第二类
使用虚拟语气的常见结构或从句：
1.*wish与hope接宾语从句的区别在于：hope表示一般可以实现的希望，宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。
2.if only 与 I wish一样，也用于表示与事实相反的愿望，其后所虚拟语气的时态与 wish后所接时态的情况相同
3.l would rather后句子用虚拟语气 只分现在和过去
在would rather, would sooner, would just as soon后的that从句中, 句子谓语习惯上要用虚拟语气，表示"宁愿做什么"
4.l as if (though)从句用虚拟语气
以as if (as though)引导的方式状语从句或表语从句，有时用虚拟语气,则与wish用法相同
