在很多同学眼里，英语中的语法是极其难学的一项内容，很多同学不知道该怎么学好英语语法。下面是我们学大教育编辑的高二英语语法辅导-虚拟语气讲解，希望能够给同学们带来一些帮助。
1、虚拟语气用于条件状语从句中
(1)表示与现在事实相反的假设，条件状语从句中的谓语动词用"过去式(be动词的过去式用were)"，而主句中的谓语动词用"would / should/ could / might + 动词原形"。如：
If I were a boy, I would join the army.
If the had time, she should go with you.
(2)表示与过去的事实相反，条件状语从句中的谓语动词用过去完成时，主句中的谓语动词则用"would / should / might / could + have +过去分词"。如：
If he had taken my advice, he would have succeeded in the competition.
(3)表示与将来事实相反，条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形，而主句中的谓语动词则用would / should/
could might + 动词原形。如;
If it were to rain tomorrow, the football match would be put off.
(4)当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，动词的形式要根据它所表示的时间作相应调整。如：
If they had worked hard, they would be very tired.(从句说的是过去，主句指的是现在)
以上就是高二英语语法辅导-虚拟语气讲解的全部内容了，希望同学们在掌握好基础知识的同时，多做一些练习，巩固我们所学的知识点。
