if引导的条件状语从句中的虚拟语气可以分为真实条件句和虚拟条件句。

1.真实条件句（Sentences of Real Condition）：凡是假设的情况发生性可能很大，就是真实条件句。例如：

If I have time , I will help you with this work.如果我有时间会帮助你做此工作的。

If time permits, we'll go fishing together.(如果有时间的话，我们就一起去钓鱼。）

2).虚拟条件句（Sentences of Unreal Condition）：当假设是不大可能实现时，就是虚拟条件句。例如：

If I were you , I would have attended the meeting. 如果我是你的话，就去参加会议了。

If he had come here yesterday, he would have seen his old friend.假如他昨天来这儿的话，就会看见他的老朋友。

If it had rained yesterday, we would have stayed at home.（如果昨天下雨的话，我们就会留在家里。）

判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。

②与现在事实相反。

③与将来事实可能相反。
