虚拟语气倒装句是什么？球例句~~

Question

如题所述

Answer 1

If I had learned it by heart , I would have pass it !
有的情况是省略了if所以句子的had提前就成了这样：
Had I learned it by heart , I would have pass it !
蓄力语气中省略if的情况下都要倒装，不论是与现在事实相反还是将来还是过去 ！追问

Try as she might,Sue couldn't get the door open.这是一个虚拟语气的倒装句，原句是
As she might try,Sue couldn't get the door open。这里面好像没有if可以省略啊。。。也要倒装么。。。

追答

这个就不是虚拟语气了，这个是as引导的让步状语从句，其概念为：as引导的让步状语从句必须倒装，如果动词货现在分词提前放在句首，谓语要补加助动词do/does/did,will等，如：
Fail as he did , he would never give up .
还有as引导的让步状语从句表语是名词的情况，这里就不多说明。
我们来看这道题：
句子是as引导的让步状语从句，所以我们必须倒装。通过上面的概念可知，我们要把动词try提前。 于是就成了倒装的句子。

Answer 2

if从句中含有were, should ,had 可以讲他们提前，并且去掉if

比如：If I had money = had i money
If i were you = were i you
If it should rain tomorrow = should it rain tomorrow
