having been done 和 done
虽然很明白一个强调动作先后一个不强调,但经常被搞糊涂
The mother and the daughter recognize each other though separated for 7 years
如这句为什么不用 having been separated,很明显recognize 是发生在separated之后而在一个选择题里却用了done 而没选having been done
貌似这里两种表达都是被动吧.....
have been dead for 这种表达是对的吧,die也是瞬时动词啊,可dead一样用嘛

separate是瞬间动词,不能用于完成时里!
