【答案解析】考查情态动词+have done结构。句意：——对不起，妈妈，我面试又失败了。——噢，那太糟糕了，你应该做好充分准备的。A.must必须；B.can可以；C.would将会；D.should应该。＂can have done＂表示对过去行为的怀疑，用于疑问句，译成＂可能做过……吗？＂；＂could have done＂表示对过去事情的假设，意思是本来能够做某事而没有做；＂must have done＂表示对过去事情的肯定推测，译成＂一定做过某事＂，该结构只用于肯定句；should have done＂的意思是＂本来应该做某事，而实际没做。故选D。
【难点梳理】
一、＂must have done＂
表示对过去事情的肯定推测，译成＂一定做过某事＂，该结构只用于肯定句。
It must have rained last night, for the ground is wet. 昨晚一定下雨了，因为地面还是湿的。
You must have been mad to speak to the servant. 你和仆人说话，一定是发疯了。
二、＂can’t have done＂
表示对过去事情的否定推测，译成＂不可能做过某事＂。
Mr Smith can’t have gone to Beijing, for I saw him in the library just now. 史密斯先生不可能去北京了，我刚才还在图书馆见过他。
Mary can’t have stolen your money. She has gone home. 玛丽不可能偷你的钱，她回家去了。
三、＂can have done＂
表示对过去行为的怀疑，用于疑问句，译成＂可能做过……吗？＂。
There is no light in the room. Can they have gone out? 屋里没有灯，他们可能出去了吗？
There is nowhere to find them. Where can they have gone? 到处找不到他们，他们可能到什么地方去呢？
四、＂could have done＂
是虚拟语气，表示对过去事情的假设，意思是本来能够做某事而没有做。
He could have passed the exam, but he was too careless. 本来他能够通过考试，但是他太粗心。
五、＂may have done＂
表示对发生过的事情的推测，意思是＂可能已经＂或＂也许已经＂，用于肯定句中。
—What has happened to George? 乔治发生了什么事？
—I don’t know. He may have got lost. 我不知道，他可能迷路了。
六、＂might have done＂
表示对过去事情的推测，might与may意思相同，但可能性更小。多用于虚拟语气结构中。

七、＂would have done＂
虚拟语气，表示对过去事情的假设，意思是＂本来会……＂。
I would have told you all about the boy’s story, but you didn’t ask me. 我本来会告诉你这个小男孩的故事，但是你没有问我。
八、＂should have done＂
意思是＂本来应该做某事，而实际没做＂。＂shouldn’t+have+done＂表示本来不应该做某事，而实际做了。含有指责对方或自责的含义。
