She doesnt know your address. 她不可能去过你家，她不知道你的地址。You could have done better，but you were too careless. 你本来能够做得更好，但你太粗心了。3. must+have done。表示对过去发生的事情或行为的较有把握的推测，是一种“十有八九”的肯定的推断，常译为“想必一定；准是”等。这一结构一般不用作否定式。否定意义的表达可用cant/couldnt have done。The ground is rather wet, so it must have rained last night, didnt it? 地面很湿，所以昨晚一定下雨了，对不对？ 4. should/ought to +have done。 表示过去该做某事而没有做的情况，表示说话人后悔、遗憾或责备的语气。 I really regret wasting the hours when I should have studied hard，but it is too late. 我真的很后悔该努力学习的时候浪费了太多时间，但现在太晚了。【名师点津】shouldnt /oughtnt to+have done表示过去不该做某事却已经做了，也表示说话人后悔或责备的语气。You shouldnt have watched TV last night. 你们昨晚本不应该看电视的。5. neednt+have done。表示过去做了其实不必去做的事，可译为“本可不必”等。You neednt have visited my uncle，as he has been all right for a long time. 其实你不必去探望我叔叔的，因为他已经痊愈了好长一段时间了。二、难点突破1. 情态动词+have done有两个主要用法：一是表示对过去发生的动作或存在的状态的推测。二是表示对过去发生的动作的遗憾或责备。要关注两种用法的差别。They left here early and should have arrived by now. (表示推测)他们一早就离开了这里，现在应该到了。You should have finished the work yesterday. (表示责备)你应该昨天就完成工作的。2. 注意neednt have done与didnt need结构的不同。She neednt have come to see me yesterday. 昨天她本可不必来看我。(实际上来了)She didnt need to come to see me yesterday. 昨天她不需要来看我。(实际上没来) 3. 含有must have done结构句子的反意疑问句的构成。 He must have studied English last night,didnt he? 昨晚他一定学英语了，是吧？ She must have heard of this,hasnt she? 她肯定已经听说过这件事了，对吧？ 【名师点津】当含有must have done结构的句子中有表示过去的时间状语时，反意疑问句要用相应表示过去的助动词，反之就用have或has构成反意疑问句。 【高考体验】情态动词解题技巧：1. 充分利用句子语境，弄清各个被考查情态动词的意思。 2. 根据上下文信息确定时态，尤其要分清情态动词表推测时涉及的是现在情况还是过去情况。3. 注意分清适用句型，是用于肯定句型，还是用于疑问句型或否定句型。1. (2013大纲版全国卷)Since nobody gave him any help, he _ have done the research on his own. A. can B. must C. would D. need解题关键：弄清since从句的含义。思路分析：选B。考查情态动词表示推测。句意：因为没有人帮助他，他一定独自完成了这项研究。can表示推测时，常用于否定句和疑问句，用于肯定句时，表示理论上对客观情况的推测；must表示有把握的推测时，只能用于肯定句，推测的可能性很大，译为“一定”；would常用于虚拟，不用于推测；need表示推测时，常用于否定句。由此可知选B。2. (2013陕西高考)The children _ lost in the woods; otherwise, they would have been at the lakeside camp as scheduled. A. must have got B. must getC. should have got D. should get解题关键：理解第二分句的句意。思路分析：选A。考查情态动词。句意：孩子们一定在森林里迷路了；否则他们会按照预定时间来到湖边营地的。根据后半句“would have been”可知是对过去事情的虚拟，must have done表示对过去发生的事情的肯定推测，根据句意，应选A。3.

A. cant B. mustnt C. neednt D. wont 思路分析：选A。考查情态动词的用法。句意：你的眼为什么那么红？昨晚你肯定没睡好。 是的，我熬夜写一篇报道了。A项cant have done表示对过去的否定推测；B项表示“禁止，不允许”，不能用于对过去的推测；C项neednt have done表示过去不需要做某事(但却做了)；D项不能用于对过去的推测。4. (2013浙江高考)I _ myself moreit was a perfect day. A. shouldnt have enjoyed B. neednt have enjoyedC. wouldnt have enjoyed D. couldnt have enjoyed 思路分析：选D。考查情态动词的用法。句意：我玩得再开心不过了这是完美的一天。D项表示不可能做过，这里是用比较级的否定形式表示最高级的意思，故选D。A项表示本不该做却做了；B项表示本不必做却做了；C项将不会做，用于与过去事实相反的虚拟语气。5. (2012江西高考)We _ have bought so much food now that Suzie wont be with us for dinner. Amay not BneedntCcant Dmustnt思路分析：选B。neednt have done表示过去本来没有必要做某事但已经做了，符合句意；may not have done 过去可能没做过某事；cant have done过去不可能做过某事；must表示推测，不用于否定句，因此选B。may not可能不，neednt不需要，cant不可能。 6.

A. ought to come B. ought to be comingC. ought to have come D. ought have come【解析】选C。考查情态动词。句意：如果你真认真对待这项工作的话，你昨天就该来。“should/ought to+现在完成时”可表示本该做而没有做的事，有责备的含义。3. He _ have finished his work;otherwise, he wouldnt be enjoying music in his study. A. should B. must C. wouldnt D. cant【解析】选B。从题干的后半部分可知，“他正欣赏音乐”，所以一定是“做完了工作”才去欣赏音乐的。所以选must，表示肯定的推测。4. What do you mean, there are only ten tickets? There _ be twelve. A. should B. would C. will D. shall【解析】选A。考查情态动词。句意：你什么意思？只有10张票吗？应该是12张。should表示可能性推测，意为“应该”，符合题意。would表过去将来；will表意愿；shall表示说话人的允许，许诺，命令,威胁等语气，均不合题意。5.

A. need B. must C. should D. can【解析】选D。考查情态动词的用法。句意：你能够确定地说的关于英国人的为数不多的事情之一就是他们对天气讨论很多。can表示“可以”。6. She _ have left school, for her bike is still here.

Ashouldnt BmustntCcant Dwouldnt【解析】选C。考查情态动词对过去的推测用法。根据“他的衣服还在这里”推测，前面一句意思是“他肯定没有走远”。must也可以表示推测，但只能用于肯定句，否定推测用cant。9. She is two hours late. What _ to her?Amay happen Bis happeningCcan have happened Dmust have happened【解析】选C。本题对时间的理解是关键。happen 一词的时间应理解为过去时，因为它指的是迟到的原因，而A、B两项是指现在，故排除。表示“可能”的疑问句不可用 must, 所以D也是错误的，因此，只能选C。10. Did you listen to the speech?No, we _ it. But we had a lot of traffic on our way. Acould have attended Bmust have attendedCcould attend Dshouldnt have attended【解析】选A。考查的是虚拟语气，表示“本来能做某事但实际上却没做”，即与过去事实相反，要用couldhave done形式。11.
