试题分析:句意:你昨天可能没有见到汤姆,他上周就去国外度假去了。(1)、“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句。如: It must have rained last night, for the ground is wet. You must have been mad to speak to the servant. (2)、“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定。can和could一般用于否定句和疑问句,could的语气较can弱。如: I didn"t see her at the meeting this morning; she can"t / couldn"t have spoken at the meeting. He can"t have finished the work so soon. (3)、“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测,might的语气比may弱一点。这种结构主要用于肯定句和否定句,疑问句改用can或could。如: They may not have known it beforehand. You might have read about it in the papers. (4)、“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些。如: You ought to / should have studied harder. 你本应该更努力学习的。(但没有) He oughtn"t to / shouldn"t have done that. 他本来就不该做那件事。(可是做了) 点评:情态动词+have done是高中阶段必须掌握的内容,是考生容易混淆的地方,也是考生容易失分的难点,考生应注意这方面的练习。 即学即练:Look at the time!
