【重点归纳】
英语里情态动词虽不是很多，却作用大，用途广，是每年高考的必考内容，特别是情态动词完成时的用法更是热门考点。为了帮助同学们更好地掌握使用这一考点，下面结合近年高考试题谈谈其主要用法。考点一：表示对过去情况的推测
●must have done
表示对过去情况或动作的肯定推测，只用于肯定句，意思是“一定做了…”。如：
He must have completed his work; otherwise, he wouldn’t be enjoying himself by the seaside.
他工作一定完成了，否则他现在不会在海边开心地玩。(05北京卷)
This cake is very sweet. You must have put a lot of sugar in it.
蛋糕这么甜，你一定加很多糖了。（05辽宁卷）
●may / might have done
表示对过去情况或动作的可能性推测，意思是“可能做了…”。如：
Some of you may have finished unit one. If so, you can go on to unit two.（09江西卷）
你们中有些人可能第一单元做完了，如果这样，你们可以接着做第二单元。
--Where is my dictionary? I remember I put it here yesterday.
--You might have put it in the wrong place.
--我字典在哪里？我记得昨天放这里了。
--也许你放错地方了。（07江西卷）
●can’t / couldn’t have done
表示对过去情况或动作的否定推测，意思是“不可能做了…”。如：
My sister met him at the Grand Theatre yesterday, so he couldn’t have attended your lecture.
我妹妹昨天在大剧院见到他的，因此，他不可能听了你的讲座。
She can’t have left school, for her bike is still here. (08天津卷)
她不可能离开了学校，因为她自行车还在这里。
考点二：表示轻微的责备或后悔
●can / could have done
表示过去本来有能力而没能做成，含有遗憾的意味。如：
--I stayed at a hotel while in New York.
--Oh, did you? You could have stayed with Barbara.
--我在纽约期间住宾馆的。
--哦，是吗？你原本可以和芭芭拉住一起的。
He paid for a seat, when he could have entered free.
他花钱买了座位，而他本来可以免费进去的。(05山东卷)
●should have done / ought to have done
表示过去本应该做某事而实际上没有做，含有责备的意思。如：
You should have warned me of the difficulty earlier.
你应该早点提醒我有困难?
There was a lot of fun at yesterday’s party. You ought to have come, but why didn’t you?
昨天晚会挺好玩的。你本该来的，但为什么没来呀？
●shouldn’t have done / oughtn’t to have done
表示过去本不该做某事而实际上却做了，含有责备的意思。如：
I am not feeling well in the stomach, I shouldn’t have eaten so much fried chicken just now.
我肚子不舒服，我刚才不该吃许多炸鸡。
Tom ought not to have told me your secret, but he meant no harm.
汤姆本不该把你的秘密告诉我，但他并无恶意。
●needn’t have done
表示过去本不必做某事而实际上却做了，含有遗憾的意味。如：
It’s only five minutes’ walk. We needn’t have taken a taxi.
只有5分钟的步行路程，我们本不必乘出租车的。
You needn’t have watered the flowers, for it is going to rain.
你本不需要浇花,因为天就要下雨了?
考点三：用于虚拟语气，表示与过去事实想法的假设
●在虚拟条件句中，如果表示与过去事实相反的情况，从句中用过去完成时，而主句中则用“would /
could / should / might + have done”。如：
If you had got up earlier, you would have caught the early bus.
如果你起得早一点，就赶上头班车了。
If you had been more careful, you couldn’t have failed in the last exam.
如果你能更认真些，上次考试不可能不及格的。
表示虚拟条件隐含在上下文里，这时仍然要用“would / could / should / might + have done”表示与过去事实相反假设。如：
Thank you for your help. Otherwise we couldn’t have succeeded in the experiment.
如果没有你的帮助，我们的实验是不会成功的。
Given more time, we might have done a better job.
如果多给我们些时间，我们本来可以做得更好些。

中考英语情态动词考点归纳与例析 【重点讲解】 情态动词表示说话人对某一动作或状态的态度，表示“必须”、“可能”、“应当”、“必要”等。情态动词本身具有一定的意义，但词义不完全，不能独立作谓 语，只能和主要动词一起构成谓语。情态动词没有人称和数的变化，没有非谓语形式。 常见情态动词用法归纳： 1.can和could:can表示能力、可能，只用于一般现在时，过去时用could。 (比较：beableto可以用于多种时态。)但could表示提出委婉的请求，或在否 定，疑问句中表示推测或怀疑时，不表示时态。例如： CouldIhavethetelevisionon?我可以打开电视吗？ Hecouldn’tbeabadman.他不大可能是坏人。 2.may和might表示允许或请求。might表示推测时，不表示时态，只是表示可能性比may小。 3.may(might)have+donesth的意思是“可能已经做了某事”，推测在过去时间里可能 发生的事情。例如： Hemay(might)havebeenhurtseriouslyinthecaraccident. 4.must和haveto都是“必须”的意思。haveto表示客观的需要，must表示说话人主观 上的看法，既主观上的必要。haveto有人称、数、时态的变化，而 must只有一种形式。另外，must用在肯定句中表示较有把握的推测，意为“一定”。 否定推测用can't。 5.musthave+donesth表示对过去可能发生的事情的推测，语气较强，具有“肯定”， “谅必”的意思。例如： --Lindahasgonetowork,butherbicycleisstillhere. --Shemusthavegonebybus. 6.should和oughtto都是“应该”的意思，可用于各种人称。 7.oughttohavedonesth/shouldhavedonesth表示本应该做某事，而事实上并没有做。否定句则表示“不该做某事而做了”。另外，oughtto在语气上比should要强。例如：Yououghtto(should)havebeenmorecarefulinthisexperiment. Heoughtnottohavethrowntheoldclothesaway. 8.need和dare既可用作实义动词用，又可用作情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句中。 9.needn'thavedonesth表示“本没必要做某事”。例如： Idressedverywarmlyforthetrip,butIneedn'thavedoneso.Theweatherwas hot. 1
