考查情态动词+have done。句意：——你昨天参加实验项目的会议了吗?——是的，但我想我（本来）不需要，因为我的主管在那里。Think/suppose等宾语从句中如果有否定词时，要把从句的否定词not前移，即“否定前移”。所以not是从句中的否定词。“need have done”意为“本来有必要做而未做”；“needn’t have done”指过去本来没必要做而做了。根据上一句时间状语“yesterday”可知本句指的是过去发生的事。结合第二句“because my director was there(我的主管)在”可推断出，我本来不必要去。故选D。

must have done用法辨析
must have done：表示对过去的肯定的逻辑推测，推定某件事情、动作或状态可能在过去发生过（存在过）。
He must have been a doctor, for he knows medicine so well. 他过去肯定是一位医生，他对医学如此了解。
Somebody must have stolen the ring. 肯定有人偷了这枚戒指. [该句所推断的偷窃动作发生在过去.]
The temperature must have dropped to below zero last night, because the water is frozen all over.昨夜的温度肯定降到零度以下，因为水都冻住了。
如果“must + have + 过去分词”句型与by now连用，还可以表示对现在完成的动作和状态的肯定推测，但实质上还是指所推测的过去的动作。例如：
They started early this morning; they must have arrived by now. 他们今晨很早就出发了，现在
肯定已经到了。

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：

常见情态动词： 情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词的基本用法： 一、can, could 1) 表示能力（体力、知识、技能）时，等于be able to 。 a)Can you lift this heavy box?（体力） b)Are you able to lift this heavy box? c)Mary can speak three languages.（知识） d)Is Mary able to speak three languages? e)Can you skate?（技能） 此时可用be able to代替。 2) can表示请求和允许。 -----Can I go now? ----- Yes, you can. / No, you can’t. 此时可与may互换。在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。（特别注明：这是在表示请求和允许的时候。） ---- Could I come to see you tomorrow? ---- Yes, you can. (No, I’m afraid not. ) can't在否定句中可以表示命令，不允许，但是语气比mustn't弱，具有劝慰的意思. 3)can表示“有时会”： A kind person can lose temper sometimes. 4）表示与五种感官和知觉的动词连用。 I can hear/ see you clearly from here. You can imagine how annoyed she was ! 2 / 17

高考情态动词练习题及答案详解 一、单项选择情态动词 1．Look! There are so many mistakes in your composition. You ________ have fixed full attention on it. A．can B．should C．need D．might 【答案】B 【解析】 【详解】 考查情态动词。句意：看！你的作文里有那么多的错误。你本应该把所有的注意力都集中在它上面的。表示“本应该做但实际上没有做”应该用should have done结构，can have done 表示可能；need表示需要；might have done表示可能做过某事；故选B。 2．—I don’t really like Janes. Why did you invite him? —Don’t worry. He come. He said he was’t certain what his plans were. A．must not B．need not C．would not D．might not 【答案】D 【解析】 考察情态动词，题干中的h e wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。 3．-- Did Jim come? -- I don’t know. He _______ while I was out. A．might have come B．might come C．must have come D．should have come 【答案】A 【解析】 【详解】 考查情态动词推测用法。句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。根据前文I don’t know.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。对过去情况的推测为情态动词+have done，must have done 一定做了某事，should have done 应该来过，不符合，故选A。 【点睛】 情态动词+have+过去分词的用法，表示推测或判断过去的情况。 can/could+have+过去分词用法：①多用于否定句和疑问句中。表示对过去某事发生的可能性的否定或质疑，意为：不可能（已经）......了-（否定句）/可能（已经）......了嘛？-（疑问句）②用于肯定句中。表示对过去没有做某事的遗憾，含有轻微的责备，意为：本来可以......的（但实际上没有......）。You could have done better, but you were too careless.（肯定
（一） 情态动词常考点 （一） 表能力 can be able to will be able to could was/ were able to could have + ?? ???? ?? ?????? ?表示现在的能力 ：表示将来的能力 表示过去的能力 过去分词：表示过去有能力做但未做 如：I am starving to death 。I can eat two bowls of rice now 。 （现在的能力）我快饿死了，现在我能吃两碗米饭。 If you have a good sleep ，you will be able to work out this problem 。 （将来的能力）如果你好好睡一觉，你将能够解出这道题。 The fire spread through the hotel very quickly but everyone was able to get out 。 （过去有能力做并且成功的做了某事）尽管这场大火迅速蔓延到了整个宾馆，但是每个人都能够逃出 去。 I could have worked out the problem ，but I didn ’t 。 （过去有能力做但未做）我本来可以解决这个问题，但没有解决。 （二） 表推测（可能性） 1. 可能性可分为客观的可能性和具体事情实际发生的可能性两种。所谓客观的（理论的）可能性即并不涉及具体某事是否会发生，此种用法常常可以说明人或事物的特征。情态动词can 可用于肯定句中表示客观的（理论的）可能性，而表示具体事情实际发生的可能性时，can 一般不用于肯定句。如： Accident can happen on such rainy days 。 这样的多雨天气有可能会发生事故。（客观的可能性） Peter may come with us tonight ，but he isn ’t sure yet 。 彼得今晚可能和我们来，但他还没确定。（实际可能性，不用can ） 2. 表示具体事情实际发生的可能性： （1）表示具体事情实际发生的可能性的层次比较 （2）表示具体事情实际发生的可能性时，may ，must 常用于肯定句，一般不用于否定句和疑问句（may not 表示“可能不”）；can 常用于否定句、疑问句或感叹句中，表示疑惑、惊讶或不相信等意思；could 既可用于肯定句，又可用于否定句、疑问句中。如： This can ’t/ couldn ’t be done by him 。（表不相信） 这不可能是他做的。 This may not be done by him 。（表不确定） 这可能不是他做的。 He could be on his way home now 。（could 不如may/ might 常用） 他现在可能在回家的路上。 Can this be done by him ？（表示疑惑、惊讶） 这可能是他做的吗？ Mr. Bush is on time for everything 。How can it be that he was late for the opening ceremony ？（表示疑惑、惊讶） 布什先生做每件事都很按时。他怎么可能在开幕仪式上迟到呢？ I didn ’t hear the phone 。I must have been asleep 。（表肯定） 我没听到电话。我肯定已经睡着了。 3. would ，could ，might 并不一定与过去时间有关，而是表示可能性弱于他们相应的现在时形式。另外should 也不一定与过去时间有关。如： This may/ might be done by him 。（后者比前者语气弱）

A．might never happen B．could never have happened C．should not happen D．needn’t have happened 【答案】B 【解析】 【详解】 考查虚拟语气。句意：虽然这并不是这次旅行的目的，但我得到了一些新的领悟，那些领悟在我的日常生活中是本不可能发生的。此处考查虚拟语气，“我得到新的领悟”发生在过去，故此处是与过去事实相反，应用could/might/would/need/should+have done，“本不可能发生”是could never have happened，故选B项。 【点睛】 本题考查“情态动词+have done”的虚拟语气，其常用表达有： could have done本能做某事而未做couldn’t have done不可能做了某事 should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了 need have done本需要做某事而未做needn’t have done本不必要做某事而做了 3．Mr. Baker, some students want to see you. ______ they wait here or outside? A．May B．Should C．Shall D．Will 【答案】C 【解析】 【详解】 考查Shall的用法。句意：贝克先生，有些学生想见你。他们是在这里等还是在外面 等?Shall用于第一、第三人称疑问句中，表示说话人征求对方的意见或向对方请示。故选

情态动词 情态动词是一种本身有一定的词义，但要与动词原形及其被动语态一起使用，给谓语动词增添情态色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后面加动词原形。 情态动词有四类： ①只做情态动词：must,can(could),may(might)…… ②可做情态动词又可做实义动词：need，will ③具有情态动词特征：have(had,has) to,used to，ought to ④情态动词表猜测：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。） 注：mustn't代表强烈禁止 must表示主观，have to表示客观。 常用的有：can may could must have use . 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。 情态动词表推测的用法小结 （一）情态动词表推测的三种句式 1．在肯定句中一般用must （一定），can,could（可能），might /may（也许，或许）。 e.g:(1)He must/can/may,might know the answer to this question. 他一定/可能/也许知道这个问题的答案。 (2)It is cold in the room. They must have turned off the heating. 屋里很冷，他们肯定把暖气关了。 2．否定句中用can’t / couldn’t（不可能），may not/might not（可能不）。
高考英语情态动词及其解题技巧及练习题(含答案) 一、单项选择情态动词 1．It_____ have been Tom that parked the car here, as he is the only one with a car. A．may B．can C．must D．should 【答案】C 【解析】 【详解】 考查情态动词表猜测的用法。句意：一定是汤姆把车停在这儿的，因为他是唯一有车的人。A. may可能；B. can可能；C. must一定；D. should应该。由as he is the only one with a car.可知一定是他把车停在这里的，非常有把握的肯定推测，故选C。 2．We’ll make the final decision on our scheme. ______ you change your mind, please inform us as soon as possible. A．Should B．Were C．Would D．Had 【答案】A 【解析】 【分析】 【详解】 考查虚拟语气。句意：我们将对我们的计划做最后决定。如果你改变主意，请尽快通知我们。根据语境，此处用虚拟语气，表示与将来相反，从句用should+动词原形，省略if，should提前，陈述句是：If you should change your mind……。故选A。 【点睛】 虚拟语气中的倒装 当虚拟条件句中含有 were，had，should时，可以将if省略，然后将 were，had，should，移至句首： 1）If he should fail, he would kill himself. →Should he fail, he would kill himself. 万一失败，他就会自杀。 2）If I were you, I would do it at once. →Were I you, I would do it at once. 假若我是你，我就会马上做。 要是我能做此事，我一定会做。 3）If he had seen you yesterday, he would have asked you about it. →Had he seen you yesterday, he would have asked you about it. 他昨天要是看到了你，他就会问你这事了。 该小题属于上述的第一种情况。should作为情态动词，有一种特殊的用法：在虚拟条件状语从句中表示与将来事实相反的虚拟语气，可以把should放在句首，即主语前，从而省略从属连词if。原来的表述为：If you should change your mind。故选A。
