【中考英语考点详解+专项训练】专题9 情态动词 (原卷版)
情态动词是初中英语里的一个重要的语法项目，也是全国各省市中考试题的考查热点。
在备战中考时，考生要牢记情态动词的结构和意义以及其表示推测时的用法，多做练习，在实践中加以区分。
中考考查重点：1. 情态动词的意义；2. 情态动词的基本句型；3. 情态动词的基本用法。
情态动词的用法情态动词用法例句can/could 表示能力，意为＂能，会＂I can read this sentence in English. 我能用英语读这句话。
表示许可时，意为＂可以，能够＂，相当于mayShe said that I could use her computer. 她说我可以使用她的电脑。
用于推测，表示可能性，意为＂可能＂，could比can更加不肯定，多用于否定或疑问句The man can’t be our teacher — he has gone to Beijing.那个男人不可能是我们的老师，他去北京了。
There is someone outside — who can it be? 有人在外面，可能是谁呢？【知识拓展】1. can的一般疑问句，肯定回答用Yes, ...can；否定回答用No, ...can’t。
—Can you play the piano? 你会弹钢琴吗?—Yes, I can. 是的，我会。
/No, I can’t 不，我不会。
2. can，could和be able to的区别：can只有现在式和过去式，而be able to可以用于各种时态；can( could)表示能力时，可用be able to代替。
I can(am able to) afford the car. 我能买得起这辆小汽车。
She has been able to come to school. 她已经能去学校了I could(=was able to) drive a car before I left school. 毕业前我就会开车。

初中英语中考情态动词考点及练习
情态动词情态动词又叫情态助动词;它们具有以下特点：⑴它们必须与其他动词连用,即：情态动词＋动词原形表示说话人对所述动作的看法,如需要、可能、意愿或怀疑等;⑵绝大多数情态动词没有人称和数的变化,即第三人称单数不加-s以be和have 开头的情态动词短语除外;⑶在意义上,情态动词具有“多义性”;例：can既可表示能力,又可表示可能、允许等意义;情态动词的基本用法1. can的基本用法：⑴表示体力或智力上的能力,即“能够,会”,可与be able to转换;例：He can speak English. = He is able to speak English.—Can you play basketball— No, I can’t.如果表示将来具备的能力,要用will be able to;例：If I have a good sleep, I will be able to do the problem.⑵表示许可,主要用于口语,书面语一般用may;例：—Can we go home now, please— No, you can’t.You can only smoke in this room.You can’t keep the library books for more than a month.⑶表示“可能”,与may同义,但一般用在疑问句中;例：What can he possibly want在否定句中,否定形式can’t表示推测“不大可能”;例：Anybody can make mistakes.The news can’t be true.与第一、二人称连用时,还可以就可能的解决问题的方式或可能的行为提出建议;在这里,也可用could使语气婉转;例：Can / Could we meet again next week 下周我们可以再见面吗—What shall we do 我们怎么办呢— We can / could try asking Lucy for help.——我们可以请露茜帮忙试试看;You can / could help me with the cooking. 你可以帮我做饭;2. may的基本用法:⑴表示“许可”,用can比较口语化;例：You may / can come if you wish. 如果你想来,你就来;You may not pick flowers in this park. 本公园内不许摘花;may not表示按规定不许可,如果用mustn’t则表示说话人不许可;我可以在这里抽烟吗—;mustn’t表示明确的禁止;⑵;例：It may rain tomorrow. 明天可能会下雨;;注意：如果,通常用例：那会是真的吗他究竟是谁呢⑶注意—Yes, you —No3. must的基本用法:⑴表示必须,强调说话人的主观意志;例：I must go now, or I’ll be late.You must be here by注意：表示“必须“时,must的否定式为或而不是mustn’t;也就是：—Must—Yes, you—No, you例：——No, you .⑵表示推测,一般只用于肯定陈述句,表示非常肯定;例：She didn’t look at me. She must be angry. 她不朝我看,一定是生气了;He is good at English. He must know the word. 他英语好,准知道这个词;You must be Mr. Jones. 想必您就是琼斯先生吧;4. have to的基本用法：have to可视为情态动词,但它与其他情态动词在用法上稍有不同;其他情态动词没有人称和数的变化,而have to却有人称和数的变化,要视主语的不同而变化;例：I / You / We / They have to….He / She / It has to….You don’t have to….意思是“必须,不得不”;have to强调客观需要;例：Sorry, I have to leave now. 对不起,现在我得走了;I’ve got to go to a meeting. 我得去参加一个会议;Will he have to work deep into the night 他将不得不工作到深夜吗5. need的基本用法：need的基本词义是“需要”,它既可作情态动词,又可作实义动词;⑴ need用作情态动词时,只用于否定句和疑问句;它只有一种形式,后接动词原形;例：I don’t believe you need worry. 我相信你没有必要焦急;—Need we go so soon我们需要这么早就去吗— Yes, we must. / No, we needn’t.是的,必须;／不,不必;So I needn’t tell him, need I 所以我不需要告诉他,对吧请比较以下两句话的不同意思：You needn’t buy the coat. 你没有必要买那件外衣;你还没买You needn’t have bought the coat. 你没有必要买这件外衣的;而你⑵My watch needs mending/to be mended. 我的手表需要修理了;We don’t need to work today. = We needn’t work today.Does he need to go right now = Need he go right now6. had better的基本用法：had bette r常略作’d better;现代语法认为它是一个助动词,因为它后接不意思是“最好做某事；还是做某事比较好”;get some sleep. 你最好睡一会儿;You’d better not do that again. 你最好别再做那件事;What had we better do now 我们现在怎么做才好呢, should, would, might表示推测：①.must多用于肯定句中表示把握性极大的推测,意思为“一定、肯定”;如: You have worked hard all day. You must be tired. 你已辛苦工作一整天了,一定累了;The book must be his. His name is on the cover. 这本书一定是他的,封面上写着他的名字;注意 must不表推测时,在肯定句中意思为“必须强调内在的职责”,在否定句中意思为“不许、禁止”,以它开头的疑问句否定回答常用needn’t或don’t doesn’t have to;如:We must obey the traffic rules. 我们必须遵守交通规则;Cars mustn’t be parked here. 此处严禁停车;—Must we hand in the papers this week 我们必须本星期交论文吗—No, you needn’t. 不,你们不必本星期交;②. can / could多用于否定句、疑问句或间上没有差别;用can时不相信的程度更强一些,如:The man under the tree can’t be Tom人不可能是Tom,他已经去英国了;Can it be true that he was fooled by a five-year-old boy 他被一个五岁的孩子愚弄了,这能是真的吗Could this be an excuse 这会不会是个借口How can you be so careless 你怎么这样粗心③.may / might多用来表示把握性不大的推测,意思为“也许、可能”, might比;注意区分“不可能”与“可能;如:Mr. Wang may know Professor Li’s telephone number.王先生也许知道李教授的电话号码;This might be the key Tom has been looking for.这可能就是汤姆一直在找的钥匙;She may not be there today. 今天她可能不在那儿;一、典型例题中考链接1．—Who is the man over there Is it Mr. Li— No, it ______ be him.

中考语法复习：情态动词讲解及提升练习一．定义：情态动词主要用于表示说话人的态度和看法。
情态动词不能单独使用必须与动词原形一起构成谓语，其否定式是在情态动词后加否定词not。
一般疑问句则将情态动词提至句首。
二、基本形式：三基本用法1. can 的用法1)表能力can表能力时意味着凭体力或脑力或技术等可以无甚阻力地去做某事。
I can climb this pole. 我能爬这根杆子。
He is only four , but he can read. 他只有4岁，但已认得字了。

2023年江苏中考英语核心语法精讲精练专题09 情态动词-含详解
专题09 情态动词情态动词是一种本身有一定的词义，表示说话人的情绪，态度或语气的动词，但不能单独作谓语，只能和其他动词的原形构成谓语。
主要有：can (could), may (might), must, need, shall (should), will (would)。
一、情态动词can/couldcan可表示能力或可能性，过去式could。
和其他的情态动词一样，can和could后面直接接动词原形，否定形式直接加not。
can用法(1) 表示能力（体力、知识、技能）。
Can you lift this heavy box? Yes, I can.（体力）Mary can speak three languages.（知识）Can you skate? No, I can’t.（技能）注意：be able to代替can, 也可以表示能力。
但can只有一般现在时和一般过去时(could), 而be able to则有更多的时态形式。
例：①You will be able to talk with the foreign teacher in English next week.下星期你将能与外国老师用英语交谈了。
②My little brother has been able to write. 我的弟弟已会写字了。
这两种情况除外：①表将来时不可以用can替换如：I’ll not be able to finish all the work tomorrow morning.①表示“经过努力才得以做成功某事”时应用be able to，不能用Can。
如：He was able to go to the party yesterday evening in spite of the heavy rain.(2) 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。

May you be happy! 祝你幸福！May you succeed！祝你成功！3. must的用法：(1).must 表示主观看法，意为“必须、一定”。
如：You must stay here until I come back.在我回来之前你必须呆在这儿。
Must I finish my homework right now? 我必须现在交作业吗？(must引导的疑问句)肯定回答：yes ,you must.否定回答：No, you needn’t/ don’t have to(2) 其否定形式mustn’t表示“ 一定不要” “千万别” “禁止, 不许”. 如：You mustn’t play with fire. 你不许玩火。
You mustn’t be late. 你一定不要迟到。
(3)must表示有把握的推测，用于肯定句,指百分百肯定。
如: The light is on, so he must be at home now.灯亮着，他现在肯定在家。
（4）①must 和have to 都有”必须”的含义，但侧重点不同：must强调说话者主观(自己）的看法。
have to强调客观（外力作用）的需要，也可以翻译为“不得不”。
I must go to school and learn some Knowledge.我必须会学校上课学一些知识。
（自己要回）I have to go to school because the holiday is over.假期结束了我不得不回学校上课了。
②must 没有人称和数的变化，而have to 有动词单三形式：has to和动词过去式：had to将来时：will have tomust not=mustn’t 表示禁止…….当must提问时，肯定回答用must。
否定回答用needn’t 和don’t have to4. need的用法：（1）.need做情态动词时：表示“需要、必须”，主要用于否定句和疑问句中，其否定形式为needn’t，意为“没有必要，不必”。
用need 提问时，肯定回答为must，否定回答为needn’t或don’t have to。
如：—Need I do my homework now?—Yes, you must .是的。
—No. you needn’t /don’t have to. 不，你不必。
(2).need 还可以作实义动词，此时有人称、数和时态的变化，如果主语是人sb.：sb. need(s) sth. 某人需要某物sb. need to do sth. 某人需要去做某事need的单三needs. 过去式needed。
变否定借助don’t/doesn’t /didn’t如：I need to pass the exam. 我需要通过这次考试。
He needs to learn English .他需要学习英语。
如果主语是物sth.:Sth. need doing 某事需要被做= need to be done这种情况下应注意两点：①.主动形式的动名词doing具有被动的含义；②.该动名词可以改为其动词不定式的被动形式而句子的意义不变。
例如：. Your car needs washing. = Your car needs to be washed. 你的车需要洗了。
5. shall 的用法：shall表示征求对方意见（多用于第一、三人称），如：Shall we go out for a walk? 我们出去散步好吗？在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。
Shall意为”要不要…..? ‘“……好吗？”’用于第一人称，表将来，而will可用于任何人称。
(1).用“Let's do...”来提出建议。
如：Let's go for a walk after supper.(2).用“What/How about...?”来提出建议；about后接名词或动词ing形式。
如：What about/How about a drink? What about/How about taking Tom with us?(3).用“Why not...?”来提出建议，表示“何不……”not面后接动词原形。
“Why not...?”实际上是“Why don't you/we...?”的简略形式。
如：Why not meet at the school gate at eight? Why don't we stay here another day? (4).用“Would you like...?”来提出建议，意思是“你想要……吗?”Would you like后可接名词或不定式。
如：Would you like a cup of tea?Would you like to go and see her?因此，如果我们说：“去游泳好吗?”英语中可有这样几种表达法：Shall we go for a swim?Let's go for a swim，shall we?What about/How about going swimming?Why not go for a swim?Would you like to go for a swim?What do you think of going for a swim?6. should的用法：（1）.should 意为“应该” ，可表示劝告、建议、义务、责任等。
如：We should protect ourselves.. 我们应该我们自己。
should not=shouldn’t +do动词原形had better 的用法：had better 意为“最好”，没有人称的变化，后接+动词原形，其否定形式为：had better not。
如：We had better go home now. 我们最好现在回家。
You had better not go home now.你最好现在不要回家。
should和had better 可以互换should not=shouldn’t和had better not可以互换7. will 的用法：Wil l①表示意愿、意志、打算，可用于多种人称。
如：I will help you if I’m free this afternoon.今天下午如果我有空，我就会帮你。
②是一般将来时的“标志词”，will+ do动词原形注意：1、will在there be句型中的形式及其句式变换。
由于“一般将来时”的结构可以用“will+动词原形”来表示，所以there be句型的一般将来时的形式就是there will be。
（一定不能说there will have）例如：There are many students in our school. →There will be many students in our school. There will be a sports meeting next week. 一定不能说：There will have a sports meeting next week.2、will 与be going to do sth区别：①. be going to 表示打算，计划，安排要去做的事情或有预兆即将发生某事，will 表示的将来时间则较远一些，如：He is going to Beijing on National Day.He will write a book some day.②. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。
