--who is John?
--______?.I saw you were shaking hands with him at the meeting.

A:Din't you meet him B: Haven't you met him.

我知道选B ，但是我的一个学生问我为什么，我有点说不清，哪位大虾给点指点！！！

由I saw you were shaking hands with him at the meeting可知，you在过去会见过他，因为是“见过”，故应为现在完成时。B是反问，意为“你没见过他吗”。

I saw you were shaking hands with him at the meeting. 这里用的是过去式“在会议上我看到你们握手”表示这个看到已经发生过了，那么前面就应该用过去完成时，表示你以前（他们握手之前）没见过他吗？Haven't you met him.

a的答案是过去的时态
而b的答案上一个完成时态，表示你大现在还没吗。与现在的动作还有联系

事情发生在过去,但是强调现在的影响

B.
