虚拟语气在主从中都用?
You shouldn’t have left home without a word;your parents worried a lot about you.
The victim would have had a chance to survive if he had been taken to hospital in time.
But for the English examination,I would have gone to the concert last Sunday.
1.虚拟语气到底在是从句中用还是在主句中用,还是在主从句中都用?
2.第二个句子中主句中用would表推测还是虚拟?从句中用了虚拟语气是不是?
对过去的虚拟用过去完成时？
but for=if only=but that？

第一句话shouldn't have done 表示本不应该做某事而做了,把它说成是情态动词的用法或者是虚拟语气都可以,因为讲的时候他们就是一起讲的,就好像是动词的时态和语态一样都要一起讲的,这个不应该说成是主句用还是从句用,就像你说的第一句话,后面就没用虚拟语气,因为后面那句话说的是客观真实情况,所以用一般过去式就可以了,如果你想知道是主句用还是从句用的话,一般是要分什么词引导的,比如if ,but for,if only,wish,it is high time ,demand ,suggest ,advise,command,request,等等,这样的词引导的时候,分三种情况,也就是与三种情况相反：与现在情况相反,与过去情况相反,与将来情况相反,这个时候才可以说是主从句都用,因为构成的时候有固定的用法的,就像你举例的第二个和第三个,你没发现他们都是主从句都用了吗,这是第一个问题.第二个问题是表示虚拟,不是推测.补充问题对过去的虚拟用过去完成式是正确的.
