　　五、Conditionals and mixed conditionals 条件句和混合条件句。条件句有四种：即：零条件句。第一条件句，第二条件句和第三条件句。

　　*按习惯分为两种，真实条件句和非真实条件句。这里的前两种属于真实条件句，后两种属于非真实条件句。

　　所谓混合条件句是指混合的条件句中含有不同的条件结构。用混合条件句谈论：想象的过去事件可能对现在的影响。

　　If he had broken the record， he would be famous now.

　　Form： If + past perfect， would + infinitive ，without to

　　（as in 3rd conditional） （as in 2nd conditional）

　　非真实条件句常常是想象中的现在状态，可能对过去有影响。
