同学你好~
在虚拟条件句中，有时可将引民虚拟条件句的连词if省略，但此时应用倒装句型，即将从句中的were, should, had 等提到句首。如：

如果她在这里，她也同意的。

If he were here, she would agree too.

→Were she here, she would agree too.

假若明天下雨，我们只好推迟这场比赛。

If it should rain tomorrow, we should have to put off the match.

→Should it rain tomorrow, we should have to put off the match.

要是我们当时早点找到他的话，我们就可以救活他。

If we had found him earlier we could have saved his life.

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

注意，如果条件从句的谓语为否定式，其中的否定词not应置于主语之后，而不能与were, should, had 等缩略成Weren’t, Shouldn’t, Hadn’t而置于句首。

我如不是警告了你，你就可能丧命了。

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

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

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


祝同学学习进步~
