Question

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

A．should come

B．may come

C．ought to have come

D．may have come

Answer 1

C

试题分析：考查情态动词+have done的用法，这句话是过去时，说明是对过去的事情的推测或是虚拟，AB都不对，C项ought to have done本应该做而没做，D项may have done过去可能做了，句意：昨天的聚会很有趣，你本应该去的，但为什么不去？选C。
点评：情态动词用于推测和虚拟语气连用一直以来都是高考的重点，对过去情况的推测虚拟语气要用情态动词+have done，具体的意思根据情态动词来判断。
