1、虚拟语气语法归纳虚拟语气的使用主要体现在三个方面：虚拟条件句、虚拟语气在某些从句中的运用，以及虚拟语气的一些特殊用法。 虚拟条件句虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句及与将来事实相反的虚拟条件句。具体情况请看下表：例句： 1. 表示与现在事实相反 If I had enough money now ， I would lend it to you.If I were you ， I would go to tell him the

8、ep. It was so quiet ; you could have heard a pin drop.虚拟语气在某些从句中的运用在某些词或短语后接的从句中要使用虚拟语气，表示愿望、建议或命令等。根据虚拟语气的形式不同，虚拟语气可以分为“should类” 和“ 过去时态类 ” 。2、虚拟语气用于名词性从句（1）虚拟语气在宾语从句中的运用。“wish + 宾语从句 ” 表示不能实现的愿望，译为“ 要是 就名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 8 页 - - -
