选择题
There was a lot of fun at yesterday's party. You ________ come，and what a pity!
A．might have
B．should have
C．could have
D．would have
答案
B
题目分析：句意：有很多的乐趣在昨天的晚会上。你本应该来，和真是可惜！might have done ="could" have done ="would" have done表示与过去事实相反，‘本能够做，而没有做’，should have done也表示与过去事实相反，‘本应该做而没有做’，有上下文可知选B。
考点: 考查虚拟语气的用法。
