英语虚拟语气中if什么情况不可省略

Answer 1

为大家介绍If的虚拟语气中的三种省略形式，当从句中含有were/should/had的形式时，If可以省略，但句子应为倒装形式，即were/should/had要提前置于句首。下面，MasterOsifu English以例句形式为大家讲解。

1.过去的情况：

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

→Had wefound him earlier, we could have saved hislife.

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

→Should itrain 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

这是可以省略的三种情况。

谓语的意思为“建议、命令、要求”如suggest\order\require等需要用虚拟语气，should在此种情况下可以省略
