1．We ________ take clean drinking water for granted. One day we may run out of it. A．needn't B．can't

C．won't D．shouldn't

【答案】D

【解析】

【详解】

考查情态动词。句意：我们不应该把拥有洁净的饮用水看作是理所当然的。也许有一天，我们会用完它。shouldn't“不应该”，符合句意。needn't不必；can't不可能；won't将不。故选D。

2．Keep up your spirits even if you _____ fail hundreds of times.

A．must B．need

C．may D．should

【答案】C

【解析】

考查情态动词。A. must必须；B. need需要；C. may可能，或许；D. should应该。句意：即使失败了几百次，也要振作起来。此处表示一种不确定的推测，故选C。

3．-- Did Jim come?

-- I don’t know. He _______ whil e 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

句。他能做得更好的）

should/ought to+have+过去分词用法：用于肯定句中。表示对过去没有做某事的遗憾，含有责备的意思，意为：本来应该......的（但实际上没有......）。用于否定句中-表示对过去已经做了某事的责备，意为：本来不应该......的（但实际上已经......了）。He should have been asleep.（肯定句，他本应去睡觉的）He shouldn't have been asleep.（否定句，他本来不应该去睡觉的）。

may/might+have+过去分词用法：用于肯定句和否定句中，表示对过去发生某事的可能性的推测，意为：或许（已经）....../或许还没有......。It is too late. He may have gone to bed. must+have+过去分词用法：表示对过去发生的事情十分肯定的推测。must表示推测时，不能用在否定句和疑问句中。I must have forgotten to tell you.（must 的引入，表达了说话者对过去忘记告诉你的这件事肯定推测）

needn't+have+过去分词

用法：表示对过去已经做了某事的后悔，意为：本来可以不必......的（可实际上却已经......）You needn't have taken a taxi here, for it was very near to my home.

4．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.“mus t + 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.

5．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。）

考查含情态动词的进行时态。句意：——把电视关掉，杰克。你现在不应该做作业吗?——妈妈，请再给我十分钟。此处表示目前应该在做某事，should“应该”，这里用含情态动词的进行时态，故选C。

10．would可以表达过去常常做的事，过去习惯发生的动作：

Pirates would bury gold in a cave. 海盗们常常把黄金藏在山洞中。

We would take a walk along the river. 我们过去常常沿河散步。

3. would后接like、love、mind等动词，表示要求、邀请、希望或询问，此时不是说过去，而是对现在的询问：

Would you like to come to my party? 你愿意来我的派对吗？

Would you mind coming with us? 你介意和我们一起吗？

比如本题，would 表示婉转的请求，征求对方的意见，故选A。

C．can have done D．might have done

【答案】D

【解析】

【详解】

考查虚拟语气中的情态动词。句意：真遗憾啊！考虑到他的能力和经验，他也许可以做得更好。can have done较少使用此结构，表示对过去行为的怀疑；用于疑问句时意为“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 done过去不可能做了某事；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。

—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 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。

【点睛】

情态动词shall的用法：

1、在主语是第一、三人称的疑问句中征求对方意见：要不要……？……好吗？如：Shall we go? 该走了吧?

25．You _____ be right but I’m going back to check anyway.

A．should B．must C．need D．might

【答案】D

【解析】

【详解】

考查情态动词。句意：你或许是对的，但我还是要回去核对一下。A. should应该；B. must 一定，必须；C. need需要；D. might或许。本题主要考查情态动词表示推测的用法，由I’m going back to check anyway可知，我对此不确定。由此可知，D项符合题意。故选D项。【点睛】

can / could用于表推测的用法

(1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。两者没有时间上的差别，只是could 比 can 更委婉，更不确定。

(2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接 be doing 结构；对过去情况作推测，后接动词完成式。

二、 may / might用于表推测的用法

表示推测，两者都可用，只是 might 比 may 语气更不确定，表示的可能性更小。如本题，根据I’m going back to check anyway可知，我对此不确定。由此可知，D项符合题意。(1) 在句型使用方面：两者均可用于肯定句和否定句，但用于疑问句时，may通常不用于句首，但可用于疑问句的句中（如特殊疑问句等），而might尽管可以用于疑问句的句首，但不算普通，通常会改用其他句式（如用could等）。

三、must表示推测的用法

must 表示很有把握的推测，其意为“一定会”“肯定会”，只用于肯定句，一般不用于否定句

或疑问句。表示对现在或未来的情况作推测，后接动词原形；表示对过去情况的推测，接动词完成式。

A. should应该；

B. need需要；

27．—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．ou ghtn’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 to不应该；C. mustn’t不可以；D. can’t不能。根据语境可知，此处表示客观性的必须，don’t have to…except to“除了……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.

会； B. mustn’t 禁止；C. needn’t不需要；D. may not不可以。本句为祈使句，所以mustn’t “禁止”符合句意。故选B项。

29．(2018·北京) In today’s information age, the 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。

30．—_______ you disturb me now? I’m busy preparing a report.

上海牛津版高一上册英语情态动词专项讲解与巩固拓展练习(有答案)

情态动词一、概述情态动词表示说话人对某一动作或状态的态度，认为“可能、应当、必要”等等，但本身意义不完全，不能单独作谓语，必须和其他动词一起构成谓语。除ought, used, have后跟不定式外，其他情态动词一律跟动词原形。情态动词主要有：can/could, may/might, must, ought to, used to, need, dare, shall/should, will/would, have to等。二、基本用法（一）can和could的用法 1．表示能力，可译为“能，会”。 I can swim. 我会游泳。 Emily can dance well and her mother could dance well when she was young. The cinema can seat 1,000 people. I could not read such an easy book when I was 7 years old. 2．表示允许、许可，常用在口语中。could比can语气上要客气。 --- Could I use your dictionary? 我可以用一下你的字典吗？ ---Yes, go ahead. 可以，用吧。（或Yes, you can. 但不能说Yes, you could.） Could/ Can you tell me how to get to the zoo? 劳驾，你能告诉我怎么去动物园吗？ He asked me whether he could take the book out of the reading room. 3. 表示可能（理论上或是逻辑判断上）。 The temperature can fall to–60℃,that is60℃below freezing.气温可降至—60℃，也就是零下60℃。 You mustn′t smoke while you′re walking around in the wood.You could start a fire. 在林子里走时勿吸烟，那样可能会引起火灾。 3．表示推测，可用于肯定句（can罕见）、否定句和疑问句，但更常见于疑问句或否定句。在此种用法中can和could没有时态的区别，只是表示可能性的大小，can表示推测的可能性比could大。 Can he be ill at home? 他会是生病在家吗？ Can the story be true? 这个故事会是真的吗？

小学英语情态动词知识点及练习

情态动词【知识要点】: 情态动词（Modal verbs）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not. 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"。疑问形式是将情态动词提至主语前。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。

【典型例题】: 【专题一】:can和could的用法【例1】Can you lift this heavy box?(体力) 【解析】表示能力(体力、知识、技能) 【练习】 1.Mary speak three languages.(知识) 2. you skate?(技能) 此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to 则有更多的时态。 I’ll not be able to come this afternoon. 当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。【例2】 -----Can I go now? ----- Yes, you can. / No, you can’t. 【解析】表示请求和允许。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。【练习】 ---- I come to see you tomorrow? ---- Yes, you . ----No, you /I’m afraid not. 【例3】Can this be true? 【解析】表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。【练习】 This be done by him. How this be true? 【专题二】may和might的用法：【例1】----M ight/ May I smoke in this room? ---- No, you mus tn’t. 【解析】表示请求和允许。might比may语气更委婉,而不是过去式。否定回答时可用can’t或mustn’t,表示“不可以,禁止”。用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。【练习】 ---- I take this book out of the room? ---- Yes, you . No, you 【例2】May you succeed! 【解析】用于祈使句,表示祝愿。
