如：Can you finish this work tonight?Man cannot live without air.— Can I go now？— Yes， you can.注意:①could也可表示请求,语气委婉，主要用于疑问句，不可用于肯定句，答语应用can （即could不能用于现在时态的简略答语中）。

高中英语语法之情态动词（一)情态动词的定义:情态动词表示说话人对某一动作或状态的态度。

（二）情态动词的特点:1)有一定词义；2）不受主语人称和数的变化影响；3)与主要动词的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待)。

情态动词无人称和数的变化, 情态动词后面跟的动词需用原形，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。

He could be here soon。

他很快就来。

We can’t carry the heavy box。

我们搬不动那箱子。

除此之外，情态助动词还有如下词法和句法特征：1）除ought和used以外，其他情态动词后面只能接不带to的不定式.We used to grow beautiful roses. I asked if he would come and repair my television set.2）情态助动词在限定动词词组总是位居第一： They need not have been punished so severely。

3）情态助动词用于第三人称单数现在时的时候,没有词形变化,即其词尾无—s形式：She dare not say what she thinks。

4）情态动词没有非限定形式，即没有不定式和分词形式，也没有相应的动名词：Still， she needn't have run away。

5）情态助动词的“时”的形式并不是时间区别的主要标志。

在不少场合,情态助动词的现在时和过去时形式都可以表示现在、过去或将来时间：Would you mind very much if I ask you to do something？ She told him he ought not to have done it。

考点13 情态动词和虚拟语气【命题解读】英语中常用的情态动词主要有can，could，may，might，must，will，would，shall，should，ought to，dare，need，used to，had better等。

在学习情态动词时应注意以下几点：同一情态动词表示不同的意义的情况；情态动词后跟各种形式的用法；尤其要注意＂情态动词+完成式＂是高考中的重点所在。

对虚拟语气的考查重点在于根据句子的语境灵活多样地运用虚拟语气，宾语从句中虚拟语气的应用，交际用语中为表示委婉而使用的虚拟语气，含蓄条件句中的虚拟语气，以及特殊句型中的虚拟语气等。

【命题预测】情态动词是2021年各地高考试题中的必考项目，每年高考单独命题区的单项填空必有一道考查情态动词的项目。

新课标卷主要在语法填空和短文改错中考查。

考点依次是：推测(可能性)→请求/允许→必要性→特殊用法。

试题的立意不偏不怪，但有效信息越来越隐蔽，语境越来越真实，考查角度越来越细致，这些因素在很大程度上增加了试题的难度。

情态动词和虚拟语气与动词的时态和语态相结合的考查是近年来高考的趋势。

【复习建议】情态动词：1. 掌握情态动词的基本用法；2. 掌握情态动词表达＂情感、态度、语气等＂方面的用法。

虚拟语气：1. 掌握虚拟语气的基本用法；2. 掌握含蓄虚拟条件句的用法；3. 掌握主从句时间不一致的虚拟条件句的用法；情态动词考向一情态动词的基本用法1）can，could与be able to1．表示能力，意为＂能，会＂。

☞Many people can use the computer.许多人会用电脑。

☞If you have a good sleep，you will be able to work out this problem.如果你好好睡一觉，你将能够解出这道题。

☞I could have worked out the problem，but I was too nervous.我本来可以解决这个问题，但我太紧张了。

高三英语高考语法专题复习情态动词概述与Can、Could考点总结与练习高三英语教研组整理热身练习（2024版）：1．No one __________ be more warm-hearted; he has a heart of gold.2．—Did you visit the famous cultural relics last month?3．I think the work _________ be completed ahead of time.参考答案与解析：1．can/could考查情态动词。

句意：没有人能（比他）更热心，他拥有一颗金子般的心。

“can’t/couldn’t…+比较级”表示最高级含义。

No one本身表示否定，故应填can/could。

2．could have visited考查情态动词。

句意：——上个月你参观了那个著名的文物吗？——没有，我们本能够去，但是我们花太多时间购物。

结合句意可知，此处表示我们“本能够”去的，但是我们花太多时间购物，所以没能去。

could have done 本能够做某事（但没做成）。

故填could have visited。

3．can考查情态动词。

句意：我认为这项工作可以提前完成。

根据句意，此处表示客观上的可能性，应用情态动词can。

故填can。

考点讲解：概述情态动词（Modal Verbs）是用来表示能力、允许、预言、可能性、建议、情感、态度等的含义的一类动词。

我们使用缩写modal v.来表示情态动词。

情态动词属于不完全动词，因此情态动词不能独自在句中作谓语，即其后需要一个实义动词和情态动词共同在句中作谓语。

这样的谓语一般也称作“复合谓语”，属于复合谓语中的一种类型。

一般地，情态动词后面接不带to的动词不定式，即动词原形。

一般地，情态动词具有助动词的语法属性，可以完成一些语法功能的需要（比如可以构成否定句或疑问句等）。

有一些情态动词有相应的过去式的形式，有一些则没有（如must 等）。

【英语语法】情态动词can的用法（附练习及答案）一、can是情态动词情态动词，本身有一定的词义，但不能独立作谓语，不以人称和数量的变化而变化，后接动词原形，也就是说情态动词和动词原形一起构成谓语。

我们常见的情态动词有：can (could)，may (might)，must，will (would)等。

接下来，我们就来学习一下情态动词"can"的用法。

二、情态动词can具体用法1）表示"能、会"，指脑力或体力方面的"能力"。

I can speak English. 我会讲英语。

Jim can swim but I can't. 吉姆会游泳，但我不会。

2）表示"可能"，常用于否定句或疑问句中，指某种可能性。

Han Mei can't be in the classroom. 韩梅不可能在教室里。

Can he come here today, please? 请问他今天能到这里来吗？3）表示"可以"，常用于口语中，指许可或请求做某事。

Can I have a cup of tea, please? 请问我可以喝一杯茶吗？You can go out. 你可以出去了。

补充：①can在口语中可以代替may，表示许可或可以。

②can't在口语中代替mustn't时，表示禁止或不准。

You can't play football in the street. 不准在马路上踢足球。

③情态动词can的过去式could，用于现在时，可使语气更委婉、更客气。

Could you help me with my English? 你能帮助我学习英语吗？三、情态动词can的基本句型1）肯定句型为：主语+can+动词原形+其它。

They can play basketball. 他们能打篮球。

情态动词情态动词是表达说话者的感情和语气的动词，它们的一个显著特点是不能单独使用，必须与实义动词的原形共同使用构成整个句子的谓语部分。

常用的情态动词罗列如下：Shall/should = ought to, will/would, may/might, can/could, must。

Need/dare 这两词既可以作情态动词，同时也可以作实义动词，我们称其为半情态动词。

1. shall:(1)征询对方意见或请示对方，多用于第一或第三人称的疑问句中。

如：Let’s go out for a walk, shall we?Shall he come in or stay outside? 让他进来还是在外面呆着？(2)说话者含有警告，命令, 承诺或者威胁的语气，多用于第二或第三人称。

如：You shan’t leave until six o’clock. 你不到六点不准离开。

No one shall stop me from speaking out the truth. 没有人能阻拦我说出真话。

What you have done now shall be paid for one day. 你今天所做的一切总有一天要偿还的。

(3)用在法律条约等文件中，表示义务，规定。

如：Each citizen shall carry his identification card when traveling.2．should(1) 等于ought to 表示应该。

如：You should wear school uniforms when you are at school.(2) Should 还可表示“居然”，说明说话者的惊讶和不理解。

如：It’s strange that he should have passed the driving test. 真奇怪，他居然通过驾驶考了。

(3) 可表示推断。

情态动词总结I 情态动词的特征：1.本身有词义。

2.不能独立作谓语。

2. 后接动词原形一起构成谓语。

3. 不随人称和数的变化。

II 情态动词各自的基本意义及用法：1.大多数情态动词（除表‘能力、许可、意志’外），都可以表示推测，其程度有差异。

按可能性程度的高低排列为：must﹥will ﹥would ﹥ought to ﹥should完全肯定完全可能很可能﹥can ﹥could﹥may ﹥might可能有可能2. 区分情态动词的否定含义：may not或许不、可能不might not可能不can’t 不可能mustn’t不许、禁止shouldn’t不应该needn’t 不必1.情态动词表推测的反意疑问句，简单来说，就是以情态动词后的时态为淮，如句子里有明确的时间状语，则以其为准。

2.以must 为例：E.g. 1. You must be hungry now, aren’t you?2. He must be watching TV , isn’t he ?3 Tom must have lived her for a long time, hasn’t he ?4. She must have arrived yesterday, didn’t she?注：如选择题中（以She must have arrived yesterday, didn’t she？为例）既有didn’t she又有hasn’t she则以didn’t she？为最佳答案。
