2025届高考英语语法复习虚拟语气知识讲解讲义
高考英语语法复习虚拟语气知识讲解一、基础知识（一）什么是虚拟语气谓语动词的作用不仅可以表示动作的时间、状态、假设（情感），也是一种语气（mood)的表现形式，表明说话的目的和意图。
（语气包含陈述语气、祈使语气、虚拟语气、疑问语气）虚拟语气用于表示假设、愿望、建议、命令等非真实或虚拟的情况，即与真实相反。
上学的时候老师经常举的一个例子，"If I were you"因为我不可能是你，这是一种不可能存在的事实，所以这是个虚拟语句。
总而言之英语中的虚拟语气可以分为两大体系：一是表示与事实相反的，或者是假象的情形，通常由if引导，叫做虚拟条件句；另一个体系是在名词从句中使用虚拟语气，表示建议，命令或者要求等语气，类似于上述美剧常用的台词。
（二）虚拟语气的用法这一部分我们主要用虚拟语气在条件句中的用法作为讲解不同情况条件从句谓语主句谓语使用场景与过去事实相反If+主语+haddone主语+should/would/could/might+have done既然是过去了，那么谈到的一切情况都已既成事实，所以过去虚拟表达的是一个与过去事实相反的情形与现在事实相反If+主语+did(be动词用were)主语+should/would/could/might+do既可能是事实，也可能是假设条件。
因此，假设条件句和事实相反句适用于谈现在的情况与将来事实相反If+主语+ did(be动词用were)If+主语+ wereto + doIf+主语+should+ do主语+should/would/could/might+do对于将来时间的虚拟不可能以事实为基础，而只能是表达说话人的一个设想或愿望。
所以，对于将来的虚拟只适用于假设条件句，而不可能表达一个与事实相反的虚拟与现在事实相反：If I had a map, I would lend it to you.如果我有地图我就借给你。
（但我没有）与将来事实相反：If I were to do the job, I would do it in a different way. 要是我来做这工作，我会是另一种做法。
