Question

There was a lot of fun at yesterday’s party．You ________ come, but why didn’t you?

1. A.
   must have
2. B.
   should
3. C.
   need have
4. D.
   ought to have

Answer 1

D
本题题意：“昨天的聚会(我们)玩得很高兴。你应该来参加的，但你为何没来呢？”ought to have done表示“过去应该做某事却没有做”，含有责备含义；must have done表示“过去一定发生了某事”，表示推测，与本题题意恰好相反。should do表示“现在或将来应该做某事”，与at yesterday’s party所表达的时间矛盾。
