虚拟语气 if You could have done other career What would it have been 为什么不是 if ..Had done 句

情态动词和实义动词、助动词一样,也有虚拟语气,它可以表示与现在或过去事实相反的非真实条件句,可以用于if条件从句,也可以用于主句.当表示与现在事实相反时,只把情态动词变成过去式（即时态往前退一格）即可,表示与过去事实相反时,情态动词要变成过去式,后面接助动词have加上过去分词.如：
If I hadn't told you,you could have been killed.（情态动词的虚拟语气用于主句）
Joyce would have been astonished if she could have heard his voice.（情态动词的虚拟语气用于if从句）
I couldn't have been angry with him if I had tried.
你给出的句子,是属于与过去事实相反的非真实条件句,这里用了情态动词can的虚拟语气,所以连接词if后面不能用过去完成时,而是要把情态动词can变成过去时的could,再后接have加过去分词的结构.希望我能帮助你解疑释惑.

虚拟语气 if You could have done other career What would it have 关于could have done 的虚拟语气情态动词中 should might could would + have done 与它们在if 虚拟语气中用法有虚拟语气would have done 的用法虚拟语气 should have done 与 could have done 虚拟语气中的would have done 与could have done结构有什么区别?什么时候用would什么虚拟语气could/should/would/might +have done 用法的差别? would/could/must have done在虚拟语气中怎么用? 虚拟语气中,什么时候用would have done,would do If引导的虚拟语气句子一般将来过去还有主语加would have done/been 虚拟语气中would could should might have done与had done都是表示过去,在用法上有 What would you have done
