IF引导的三种时间虚拟条件句结构

作者: admin来源: 网络文章 时间: 2019-03-13

虚拟语气中,if引导的虚拟条件句是最为核心的,很多学生问我对应的三种时间结构是什么,今天我给各位同学进行了罗列。

  从句 主句
与现在事实相反 if + 主语+ did/were… 主语+ would/could/should/might do…
与过去事实相反 If+主语+had done… 主语+would/could/should/might have done…
与将来事实相反 If+主语+ did/were to do/should do… 主语+ would/should do

给大家附上三个例句:

If I were you, I would try it.   与现在事实相反

If he had realized that, he would have run away while there was still time. 与过去事实相反

If it were to/should rain tomorrow, the meeting would be put off. 与将来事实相反
