【点睛】
情态动词+ have done结构:
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.
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: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.
4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余.如:I needn't have bought so much wine—only five people came.
5.“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)
6.“would + have + 过去分词”表示对过去的某种情况进行猜测,或本来要做某事却因某种原因未做成,通常用来说明某一情况,但不像用should或ought to那样含有责备之意.如:
I guess the poet would have been about twenty when she wrote her first poem.
Another worker wouldn't have acted like that.
