高中英语语法虚拟语气讲解
虚拟语气概念:虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。
条件句可分为两类，一类为真实条件句，一类为非真实条件句。
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
一、1真实条件句真实条件句用于陈述语气，假设的情况可能发生，其中if 是如果的意思。
时态关系句型：条件从句主句一般现在时shall/will + 动词原形If he comes, he will bring his violin.典型例题The volleyball match will be put off if it ___. A.will rain B. rains C. rained D. is rained 答案B。
真实条件句主句为将来时，从句用一般现在时。
注意：1) 在真实条件句中，主句不能用be going to表示将来，该用shall, will.(错) If you leave now, you are never going to regret it.(对) If you leave now, you will never regret it.2)表示真理时，主句谓语动词便不用shall (will) +动词原形，而直接用一般现在时的动词形式。
2.非真实条件句1）时态：可以表示过去，现在和将来的情况。
它的基本特点是从句时态逆推。
[例句]①.If they were here now , they would help you .如果他们在这里，他们就会帮助你。
②If you had come earlier , you would have met him.如果来得早些，你就会见到他了。
③. If it should rain , the crops would be saved.如果下雨，庄稼就能得救了。
3. 混合条件句、错综条件句虚拟条件句中的主句和从句的动作发生在不同的时间，这时主句和从句的谓语动词的形式根据各自发生的时间来表达。

高中英语虚拟语气语法讲解
虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，虚拟语气所表示的含义不是客观存在的事实。
在条件句中的应用，条件句可分为两类，一类为真实条件句，一类为非真实条件句。
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
一、虚拟语气在从句中的使用
虚拟语气即表达不可能发生或与预期相反的情况。
首先我们应熟悉它在三种时态里的使用情况，这是正确使用虚拟语气的基础。
这三种时态是：现在；过去；将来。
If it were not for their help, we should be in a very difficult position.
如果不是他们的帮忙，我们就会处于一个非常困难的境地。
如果我们早一点动身的话，就不会误车了。
If she hadn’t been ill, she might have come. 如果她不是病了，可能会来的。

２．省略句
在条件句中，可省略 if，把were ,had, should 提到 句首，变为倒装句式． If I were at school again, I would study harder. Were I at school again, I would study harder.
