I met one of my old schoolmates yesterday.I_her for several years.
A haven not seen B had not seen
我知道如果没有前面那句一定选B,但有前面那句应该选什么?
讲完答案,再讲讲原因啊!顺便讲一下关于现在完成时,过去完成时和一般过去时的区别,简单点就行了,举点例子最好

筒子,因为前面一句说了是昨天见着我的同学的,就是说在昨天之前我已经没看见她好几年了,没见着的动作是发生在在遇见之前,所以是过去的过去,所以说用过去完成时.选B.
现在完成是从过去发生的动作持续到现在,对现在有影响,比如说I have had an apple.(所以现在不饿).而过去式I had an apple.就是过去发生的动作,与现在无关了.
过去完成时是用来表示发生在过去的过去的动作.比如说昨天在看比赛之前我吃了一个苹果:I had had an apple before the match started yesterday.
希望能对你有点帮助!
