Question

高中英语~请问if省略句的倒装，是不是只有对过去和将来的虚拟的时候，才能倒装？因为出现的这几个都不是“if+主+动词原形”的形式，就是对现在的虚拟的条件句的形式。非常感谢！

Answer 1

并不一定；

是否可以倒装只取决于if引导的从句中是否有were/had/should 三个词；

 

If 引导条件状语从句分为要虚拟和不要虚拟两种情况；

而其中要虚拟的从句中，存在可以倒装的情况（注意不是一定要倒装，是可以）

 

例如：下面都是要虚拟的情况，并且可以倒装。

对过去虚拟

If they had been told the rules, they wouldn't have failed.= Had they been told the rules, they wouldn't have failed.

对现在虚拟

If I were you, I would leave now. = Were I you, I would leave now.

 

对将来虚拟

If I were you, I would never regret. = Were I you, I would never regret.

If it should snow tomorrow, there would be no place to go. =Should it snow tomorrow, there would be no plave to go.

追问

不好意思，请问下，对现在的虚拟，不是必须用“if+主+动词原形”吗？were不是动词原形啊。。。

追答

对现在的虚拟不是用动词原形，是用动词过去式，如果遇到be动词，就用were
例如：
If you did that for me, I would......（事实上你不会帮我做，要用虚拟）
If you were here, you would understand...(事实上你不在这儿，要用虚拟)

关于If + 主语 +动原，这是真实条件状语从句，不是虚拟语气
