问题 Michael failed the exam. He ______ have spent so much time playing computer games and chatting online.

选项 A、mustn’t
B、couldn’t
C、wouldn’t
D、shouldn’t

答案 D

解析本题考查的是“情态动词+have done”的用法。这一结构有的种意义：1)表示对过去事情的一种推测；2)表示与过去事实相反。should have done表示与过去相反的假设，即“本应该做某事，但事实上却没有做”，是虚拟语气的一种用法，此句是should have done的否定式，意思是“本不应该做的事，但事实上做了”，因此选D项。
