高中英语2025届高考语法复习虚拟语气知识讲解
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。
（言外之意不是我做这个工作，用虚拟表达是我做这份工作的可能性很低）与过去事实相反：If anything had happened, he would have let us know.如果发生了什么情况，他早就通知我们了。
（所以没事发生）它们的共性都是表示与事实相反或者实现可能性不大3.特殊情况①在极少情况下，从句的谓语动词用原形，主句的谓语动词可用陈述语气（比较官方，正式，大气的说法，口语很少使用）If that be the official view, it cannot be accepted.如果这是官方的看法，这是不能接受的。
②if可以省略，但是语序要改为倒装Were I Tom I would refuse.如果我是汤姆我会拒绝。

2023届高考英语虚拟语气的用法归纳讲义
虚拟语气如何用（1）对现在状况的虚拟对现在状况的虚拟，条件句中谓语动词用一般过去时，主句用“would/should/might/could+动词原形”。
（2）对过去状况的虚拟对过去状况的虚拟，条件句中谓语动词用过去完成时，主句用“would/should/might/could+have+过去分词”。
（3）对将来状况的虚拟对将来状况的虚拟，条件句中谓语动词可用should do, were to do或动词的过去式三种形式表示，但意义略有不同。
should表示的可能性比较大，动词过去式的可能性次之，were to do的可能性比较小。

（4）错综时间条件句有时条件从句谓语动词表示的动作和主句谓语表示的动作发生的时间不一致，这类句子称为错综时间条件句。
此时主从句动词的形式应通过各自所表示的时间开展调整。
If you had taken my advice then, you wouldn't be in trouble now.假如当时听我劝，你现在就不会有麻烦了。
（if条件句是对过去的虚拟，故用过去完成时，而主句是对现在的虚拟，故用“would+动词原形”形式。
）（5）表示“建议、命令、要求、坚决做”等动词后的宾语从句常用“(should+)动词原形（6）wish后的宾语从句wish后的宾语从句用一般过去时表示现在的状况，用过去完成时表示过去的状况，用would/could do表示将来的状况。
