“难道
真的做了吗”，表示怀疑；need have done 需要做某事，实际上却未做（表示虚拟语气）；must have done 一定做了某事（表示对过去发生的事情的肯定推测）；might have done 表
示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。故D 正确。【点睛】本题是高考必考考点，一定要牢记句型意思。must have done 过去肯定做了某事。should have done本应该做而实际未做。can't have don过e 去不可能做了某事；shouldn 't have done 本不应该做而实际做了。need have done 本有必要做某事而没做；needn' t have done本没有必要做某事；注意没有mustn' t have done的形式。

【点睛】
would 的用法
1.would 最常见的用法是：相对于一个过去时间点的后来“将要”做什么，比如：He said he would meet me at the station. 他说他会在车站接我的。这句中的would meet 是相对于said
（过去说）之后要做的事情。又如：She thought she would have to ask someone for help.
她
当时想，她得找个人帮忙。
10．Frankly speaking, I am not sure whether I _ this in the old days with that kind of equipment, which looks quite odd and ridiculous.

【详解】
考查情态动词+have done 。句意：坦率地说，我不确定在过去我是否会用这种设备做这件事，这看起来很奇怪和可笑。A. should have done 表示本应该做某事，而实际上没有做某事；B. need have done 表示本来需要做某事而没有做；C. would have done 虚拟语气，表示对过去事情的假设，意思是“本来会做”；D. must have done 表示对过去事情的肯定推测，译成“一定做过某事”。由“in the old days可知”，本句表示对过去事情的假设。故选 C 项。

14．It is really cold and the ground is wet; it _ have rained last night.
A．might B．must
C．can D．should
【答案】B
【解析】
【详解】考查情态动词辨析。句意：天气很冷而且地面是湿的，昨晚一定下了雨。根据上文the ground is wet 可知，“昨晚下了雨”是肯定的，故用must have done 必“定做了??”表示对过去十分有把握的推测，故选B。
【点睛】
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。
中国学生的常见病句是：They...; they certainly have arrived. 病句的句义是“他们当然已经到达了。”（这不是对过去的肯定推测，而是断定动作已经完成。）
15．The accident which left 15 people on board dead if both the angry female passenger and the bus driver had kept calm.
A．should have avoided B．should be avoided
C．could have avoided D．could have been avoided
【答案】D
【解析】
【详解】
考查“情态动词+完成式”。句意：如果愤怒的女乘客和巴士司机保持冷静，这起导致15人
死亡的事故本来是可以避免的。could have done “本来能做而没有做”，且句子主语The accident 和谓语动词avoid 之间是被动关系，结合句意可知答案为D。
【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. “ maym / ight + 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 /u oght 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. “ woul ＋d 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.
16．—I have something important to tell John. But I can
His cell phone is here, so he ______ have gone too far.
A ． mustn 't C ． wouldn 't
【答案】 D
【解析】
详解】 在这儿，所以他不可能走得太远。根据句意可知，此处是对过去的一种猜测，此处是表达 不可能 ??，用 can ' t have don 。e 故选 D 。 17． — What ' s wrong with you? —Oh, I am sick. I _______ so much ice cream just now.
A ． shouldn 't eat
B ．mustn 't eat
C ． couldn 't have eaten
D ．shouldn 't have eaten
【答案】 D
【解析】
【详解】 考查情态动词和虚拟语气。句意： ——你怎么了？ ——我生病了，我刚才不应该吃那么多 冰激凌。 A. shouldn 't ea 不t 应该吃； B. mustn 't ea 禁t 止吃； C. couldn 't have eate 不n 可能 吃； D. shouldn ' t havea teen 本来不应该吃。根据 just now 可知，是发生在过去，故选 D 。 t find him. B ． needn 't
D ．can 't
考查情态动词。句意： 我有重要的事情要告诉 John ，但是我找不到他。
他的手机
18．He ____ his stay in France, didn't he? He looks amazingly different.
A．will have enjoyed B．should have enjoyed
C．can have enjoyed D．must have enjoyed
【答案】D 【解析】【详解】考查情态动词+have done。句意：他在法国一定过得很愉快，是吗?他看起来很不一样。
must have done 一定做某事。表示对过去事情的较有把握的推测。由“ He looks amazingly different. 可知”，他在法国一定过得很愉快。所以这是对过去事情的较有把握的推测。故选D 项。
19．—Did you attend the meeting for the experiment project yesterday?
—Yes, but I don ' t think I ____ because my director was there.
A．need to have B．need to C．needed to D．need have
【答案】D
【解析】
【分析】
【详解】
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 don指e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。
20．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。
21．（2018 北·京） In today 's information, tahgee loss of data cause serious problems for a company.
A．need B．should
C．can D．must
【答案】C 【解析】考查情态动词。句意：在今天的信息时代，数据的丢失有时会对一个公司造成严重的问题。数据丢失造成严重问题是客观上会发生的情况，即“客观可能性”，故该空应用情态动词can。C 选项正确。其余情态动词均没有该用法。need 需要；should 应该，竟
然；must 必须，肯定。
点睛：can的基本用法：1. （表示能力、功能）能，会；2. （表示推测）可能，可能会；3.（表示允许，请求）可以；4.（表示客观可能性）有时会。
22．—What do you think we can do for our aged parents?
—You ______ do anything except to be with them.
A． don ' t have to B． oughtn 't to C． mustn 't D． can 't
【答案】A
【解析】
【详解】考查情态动词辨析。句意：——你认为我们能为年迈的父母做些什么？——除了和他们在一起，你不必做任何事情。A. don ' t have to不必；B. oughtn 't t不o 应该；C. mustn '不t 可以；D. can '不t能。根据语境可知，此处表示客观性的必须，d on' t have to ?except除to “ 了??不必做??”。故选A。
【点睛】
have to 表示客观需求时，使用have to 的情况要比must 多。have to 受客观条件或环境迫使而“不得不”做某事，突出客观性。
must 一般则表示命令或说话人主观认为必须要做某事，含强调语气，侧重主观性。有时候也使用be+不定式表示需要做某事，但语气较弱一些。如：I am to do it, whether I like it or not.
must 表示客观性的需要时，一般翻译为“总是要（会）”。如：All men must die. 人故有一死。ought to 表示必须时，偏责任，推想等。如：You ought to work hard.

D

详解】
考查情态动词。句意：——我的词典在哪里？我记得昨天放在这里了。——你或许放错了地方。“might have +动词+ed 形式”表示过去可能完成的动作。根据所提供的情景Where is my dictionary? I remember I put it here yesterday. 可判断出把词典放在某个地方发生在过去，所以要用“ might have +动词+ed 形式”。“ should have +动词+ed 形式”表示“过（去）本来应该做某事”。must 意为“一定”，是肯定的推测，与所提供的情景的矛盾。
might put 表示现在发生的事。故选D。

came. 5. “ should / ought to + have +过 去分词 ”表示过去本该做某事但
没做 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. “ woul ＋d 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.
分析句子可知，由 “ what I did 可知”，此处是对过去事情有把握的推测， m ust have done 定是做某事了 ”。故选 D 项。

情态动词精品学案 情态动词解读: ①本身有一定的词义，表示说话人的情绪、态度或语气的动词。 ②不能单独作谓语。 ③和其他动词原形构成谓语。 ④谓语动词之前。 ⑤无人称和数的变化。 ⑥否定式构成是在情态动词后面加“not”。 ⑦个别情态动词有现在式和过去式两种形式，过去式可以用来表达更加客气、委婉的语气，时态性不强，可用于过去，现在或 将来。 经典例句： We can be there on time tomorrow. 我们明天能按时去那儿。 May I have your name? 我能知道你的名字吗？ Shall we begin now? 我们现在就开始吗？ How dare you treat us like that! 你怎么敢那样对待我们! We can't carry the heavy box. 我们搬不动那箱子。 情态动词考点： 1.情态动词表示推测。 2.情态动词的基本用法。 3.情态动词的答语。 1 / 17
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
高考英语情态动词讲解
（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）

高考英语情态动词及其解题技巧及练习题(含答案)
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。

A．needn’t do B．shouldn’t have done C．mustn’t do D．needn’t have done 【答案】D 【解析】 【详解】 考查情态动词辨析。句意: ---凯瑟琳，我已经为你打扫了房间。 - - -谢谢。你本不必这么做的。我自己能行。A. needn’t do不必做某事；B. shouldn’t have done本不应该做某事； C. mustn’t do禁止做某事；D. needn’t have done本不必做某事。由“Thanks. I could manage it myself”可知，needn’t have done“ 本不必做某事，而实际上做了某事”符合句意。故选D 项。 2．Paul did a great job in the speech contest. He many times last week. A．need have practised B．might practise C．must have practised D．could practise 【答案】C 【解析】 【详解】 考查情态动词。句意：保罗在演讲比赛中表现得很好。他上星期一定练习了很多次。must have done是对过去发生的动作最有把握的猜测，意思是“一定”。故C选项正确。 3．It is really cold and the ground is wet; it ________ have rained last night. A．might B．must C．can D．should 【答案】B 【解析】 【详解】 考查情态动词辨析。句意：天气很冷而且地面是湿的，昨晚一定下了雨。根据上文the ground is wet可知，“昨晚下了雨”是肯定的，故用must have done“必定做了……”表示对过去十分有把握的推测，故选B。 【点睛】 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.
