Question

情态动词的虚拟语气中，只有哪个可以倒装？

谢谢

Answer 1

在有情态动词的虚拟语气条件句中，只有should可以倒装。倒装时，把should移至句首，去掉if。例如：
If you should prepare to go there ,I should go with you.
= Should you prepare to go there ，I should go with you. 如果你准备去那里的话，我就和你一块去。
若虚拟语气条件句中有动词were,should或had, 都可以把这三个词放在主语之前,去掉if,变成倒装句。例如：
If I were a bird,I would fly.
=Were I a bird,I would fly.如果我是一只小鸟，我就会飞翔。
If we were confident ,we would be able to overcome all difficulties.
= Were we confident ,we would be able to overcome all difficulties.如果我们有信心，就能够克服所有的困难。
If he should agree to go there, we would send him there.
=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。
If you had come，we wouldn't have been so busy.
= Had you come yesterday, we wouldn't have been so busy.如果你昨天来的话，我们就不会那么忙了。
If I had enough time, I would go to his help.
= Had I enough time, I would go to his help.如果我有足够的时间，就去帮助他。

Answer 2

Should。当虚拟条件句中含有should时，句子要部分倒装，此时可以把if省略，然后把should提到句首，例如：Should_it_rain ， the_crops_would_be_saved . ＝Were_it_to_rain（If_it_should_rain） ，the_crops_would_be_saved.如果下雨，这些作物就可以保全下来了。Good_luck!

Answer 3

分成三类：
1当与过去相反时 去掉if 把had前置，Had you come to the party,you would have met ZhouBiChang
2当与现在相反时 去掉if 把were前置：Were I you ,I would go back
3当与将来相反时 去掉if 把should前置Should it rain ， the crop should be saved
切忌，只有这三个词这样倒装！！！
