有must have been的用法么?虚拟语气里面?
Do you still remember when we went to the Great Wall?
I can't remember it well,but ____ sometime last autumn.
A it must have been
B it could have been
这题不能选A么,是没有这种用法还是意思有不对?
我看到语法书里有 主语+ would(could might should) +动词原型...没看到有must

是意思不对,这种用法有
前句说“记不清了”,若选A,意思是“一定在去年秋天的某个时候”,有些前后矛盾
选B,表示“应该是”
补充一下,这里不是虚拟语气,只是情态动词表推断
