省略if的虚拟条件句中

省略if的虚拟条件句中，

were, had, should与主语倒装。

Were I you, I would do the work.

Were I (= If I were) in your place, I wouldn’t give it up so early.

Had I (= If I had ) known, I might have joined you in the discussion.

Should you (= If you should) be interested, I have a book on the subject you might like to see.

当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件

从句要用倒装语序，即将were, should, had等词置于句首，这种多用于书面

语。如：

Should he agree to go there, we would send him there.

要是他答应去的话，我们就派他去。

Were she here, she would agree with us.

如果她在这儿的话，她会同意我们的。

Had he learnt about computers, we would have hired him to work here. 如果她懂一些电脑知识的话，我们已经聘用他来这里工作了
