Question

if倒装的省略三种时态

Answer 1

　　1.过去的情况：

　　If we had found him earlier, we could have saved his
life.要是我们当时早点找到他的话，我们就可以救活他。

　　→Had we found him earlier, we could have saved his life.

　　2.现在或将来的情况：

　　If she were here, she would attend the meeting too. 如果她在这里，她也参加会议。

　　→Were she here, she would attend the meeting too.

　　3.将来的情况：

　　If it should rain tomorrow, we should have to stay at
home.若明天下雨，我们只好呆在家里。

　　→Should it rain tomorrow, we should have to stay at home.

　　注意：若遇到否定词not时，不能与were/should/had缩略为Weren’t/Shouldn’t/Hadn’t而置于句首。

　　如：If I hadn’t warned you, you could have been killed.

　　正确：Had I not warned you, you could have been killed.

　　错误：Hadn’t I warned you, you could have been killed.
