初中英语语法详解精练 13第十三章 助动词和情态动词

初中英语语法详解精练 13第十三章 助动词和情态动词

第十三章助动词和情态动词要点概览◎助动词和情态动词的定义◎can(could),may(might),must,need◎Will you? 和Shall I/we?◎would和should◎have to◎易混易错点剖析知识讲解一、助动词和情态动词用法1.助动词是协助主要动词构成谓语动词词组的词。

汉语中只有助词,而没有助动词。

这又是英汉两种语言的一大差别。

英语的助动词,就是起辅助作用的动词,本身没有独立的词义,不能单独做谓语,在句子中只起语法作用,和实意动词一起构成谓语(叫复合谓语),表达否定,疑问,时态,语态和其他语法关系。

其2.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, 只能和其他动词原形构成谓语,没有人称和数的变化。

把情态动词放在句首、句尾用问号便构成疑问句;在其后加上not或never等否定词就构成否定句。

如:My mother can drive. 我妈会开车。

My mother can’t drive. 我妈不会开车。

Can your mother drive? 你妈会开车吗?Can’t your mother drive? 你妈不会开车吗?You needn’t look at me like that. 你不必那样瞧着我。

常用的情态动词有can, could; may, might; must; should; need; dare; ought to 等。

【即时体验】1. —Do we have to finish our homework this afternoon?—Yes, you ________.A. mustB. canC. mayD. need【解析】A 情态动词的用法。

情态动词have to为“不得不”,其肯定回答为“Yes, you must”,否定回答为“No, you needn’t”。

故选A。

2. –Look at that girl! Is it Susan?—No, it _______ be her. She has gone back to her hometown.A. mustn’tB. can’tC. needn’tD. wouldn’t【解析】B 情态动词的用法。

浙江省中考英语总复习 第2部分 语法专题复习篇 第33课时 动词和动词短语(精讲)试题 外研版-外研

第33课时动词和动词短语动词属于实词,用来表示动作或状态。

动词按句法功能可分为实义动词、系动词、助动词和情态动词。

对于动词的考查主要涉及以下考点:1.常用动词的变化形式(第三人称单数形式、现在分词、过去式和过去分词);2.系动词、助动词和情态动词的基本用法;3.常见动词短语的固定搭配及运用。

实义动词实义动词表示动作或状态,在句中能独立作谓语。

1.根据后面是否能直接带宾语可分为及物动词和不及物动词。

(1)及物动词及物动词本身意义不完整,需要接宾语才能使意义完整,主要用于三种句型中。

①动词+宾语。

如:I cleaned my room yesterday.我昨天打扫了房间。

(clean后有宾语room,为及物动词)②动词+宾语+宾语补足语。

如:Sad movies make me cry.悲伤的电影使我哭泣。

(省略to的不定式cry作make的宾语补足语)③动词+双宾语(间接宾语和直接宾语)。

如:My mother bought me a sweater.妈妈给我买了一件毛衣。

(bought后接双宾语)(2)不及物动词①不及物动词本身意义完整,无需接宾语。

如:He works hard.他努力工作。

(work后无宾语,是不及物动词)②若不及物动词要接宾语,其后需加适当的介词。

如:I like listening to music.我喜欢听音乐。

(listen为不及物动词,后加介词to才能接宾语)2.按动作发生的方式、发生过程的长短可分为延续性动词和非延续性动词。

延续性动词表示能够延长的动作,如:learn,work,keep,sleep,live等,可以与表示时间段的状语(for+时间段,since+时间点,since 从句)连用。

非延续性动词也称瞬间动词,表示不能延续的动作,动作发生后立即结束,如:open,die,begin,finish,e,borrow,lend,buy等,不能与表示时间段的状语连用。

初中英语中考情态动词考点及练习

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.

2021年上海市中考英语语法复习:情态动词讲解及提升练习(有答案)

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。

Fire can’t destroy gold. 火烧不毁金子。

2)表可能性多用于否定与疑问结构中,但也可用在肯定句中。

Can the news be true? 这消息可能是真的吗?It can’t be true. 它不可能是真的。

What can he possibly mean? 他可能是什么意思?3)表示允许(和may意思相近)常见于口语。

Can (May) I come in ? 我能进来吗?Can I smoke here ? 我可以在这里抽烟吗?2.could的用法1)表过去的可能和许可,Father said I could swim in the river. 爸爸说我可以在河里游泳。

2)表过去的能力I could swim when I was only six. 我刚六岁就能游泳。

3)表“允许”。

可表示委婉客气的提出问题或陈述看法,不是can的过去时态。

---Could I use your bike? ---Yes, you can./No, you can’t.注意:be able to 表示能力,意为“能够做成某事”,相当于can 的用法,但是有区别:can泛指一般的能力;be able to 则主要指成功做了某件事的能力。

3. may(might)的用法1)表示请求、可以、允许。

You may drive the tractor. 你可以开那台拖拉机。

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。

初中英语语法专题动词语常用短语

初中英语语法专题动词语常用短语初中英语语法专题动词一、概念及分类动词(Verb)一般就是用来表示动作或状态的词汇。

我们接触的动词包括实义动词(Notional Verb)、系动词(Linking Verb)、助动词(Auxiliary)、情态动词(Modal Auxiliary)。

二、动词的用法1. 实义动词按照句法作用可以分为及物动词和不及物动词;按照动词的持续性可分为延续性动词和非延续性动词。

及物动词(Transitive Verb) :本身意义不完整,后面直接跟宾语。

例:I like the book very much. 我非常喜欢这本书。

You can call me Lucy. 你可以叫我Lucy.Give me a glass,please. 请给我一个杯子。

不及物动词(Intransitive Verb):本身意义完整,后面不可以直接跟宾语,若要跟宾语,必须先在其后加上某个介词。

例如: She dances well. 她舞跳得很好。

Look at me. 看着我。

延续性动词(Durative Verb):表示动作是可以持续的,可以和表示时间的状语连用。

例如:We have lived here for 20 years. 我们已经在这里住了20年了。

非延续性动词(Non-durative Verb):表示瞬间动作,动作一旦发生立即结束,不能和表示一段时间的状语连用。

如果和表示一段时间的状语连用,要用其它的词代词。

例如: She has kept the book for 2 months. 她借这本书已经2个月了。

(这里不能用has borrowed)2. 系动词系动词本身有词义,但不能单独使用,和表语在一起组成主系表结构,说明主语的状态、性质、特征和身份。

常见的系动词如下:be 动词am/is/are/was/were变化系动词get/turn/come/go/become/grow感官系动词feel/sound/look/smell/taste后面必须加形容词保持系动词keep/remain/stay似乎系动词seem例如: I am a student. 我是一个学生。
