Question

-Did you enjoy meeting your old friends yesterday? -Yes,I did. I_them since we graduated from

college.A didn't see B haven't seen C hadn't seen Dwouldn't see 为什么
答案选C 为什么

Answer 1

我认为答案应该选C，因为问题问的是是否enjoy yesterday，而作者是从graduation 到yesterday 没有见到他的朋友，这段时间是过去的过去，因此应该用过去完成式~
如果这道题问的是Do 有enjoy meeting your friends today?那么答案应该是B，因为是过去到现在的这段时间，应该用现在完成式~
希望帮到你哦~~~^ ^~~~

Answer 2

选B，句子中典型提示语since证明应该要用完成时，事情影响还持续到现在，所以就用现在完成时态。
