请问这句话中，as soon as 引导的时间状语从句，从句用的是一般过去时，主句用的是什么时态呢？

Question

In my personal opinion, you should have done this as soon as you found out he was stealing.

Answer 1

主句用的是情态动词的完成时，用来表示虚拟语气。
as soon as 的时间状语从句，正常情况下主从时态相同，如：I dialed 110 as soon as I found out he was stealing. 我一发现他在行窃就立即拨打了110.

而这句的意思是：你发现他在行窃时，当场就应该……。（实际是并没有那么做）是与过去事实相反，用虚拟语气。从句的形式是：could/would/should/ought to have done

Answer 2

主句用的是should加现在完成时，这个用法的意思是，本应该怎么，实际却没有做本回答被提问者采纳

Answer 3

这是“与过去相反”的虚拟语气吧。
