动词不定式热点透视 篇1

在英语学习中, 我们会经常遇到有的动词宾语只能用动词不定式, 而有的只能用动名词, 甚至有极少数的动词宾语即可以用带to的动词不定式也可以用不带to的动词不定式。这些英语的习惯用法如果平时不注意观察, 就会引起使用上的错误, 本人把教材中出现的有关这方面的动词进行了归纳, 供学习时参考。

一、用于动词宾语的动词不定式而不能因于动名词的动词如下这些:

1) fail:The student failedto passtheexam lastterm.

教学目标

1.学会什么是动词不定式 2.会使用动词不定式 重难点

1.能正确的使用动词不定式的各种用法 教学步骤

Grammar: 动词不定式 Ⅰ.不定式句法功能

1.作主语:The cat said, “To take roller coaster” is terrible.不定式短语作主语时,可以直接放在句首,但在很多情况下,尤其是在疑问句和感叹句中,往往放在谓语之后,而用先行代词it作形式主语。→ The cat said, “It’s terrible to take roller coaster.” How long did it take you to take roller coaster? How terrible it is to take roller coaster? 不定式作主语常见句型:

a)It is + adj.(easy, important, difficult…)+ 不定式

b)It is + n.(a pity, a pleasure, one’s duty, a shame)+ 不定式

eg.It’s my duty to teach you how to be a student of No.3 Middle School.c)It takes/needs/requires + some time(hours, months, days, patience…)+ 不定式 eg.It requires patience to be a good teacher.2.作表语:当句子的主语是aim, idea, policy, question, suggestion, wish, task, duty, job, purpose等或者主语是what引导的名词性从句时,后面可以用不定式做表语,用以说明主语所包含内容。

eg.Our most important task now is to make a plan.注:作表语的不定式都带to,但当主语部分有实义动词do时,to可以省略。eg.The only thing we can do now is wait and see.3.作宾语

The cat said “Remember not to take it next time!”.a)可以直接用不定式作宾语的动词很多,常见的有:agree, afford, tend, ask, decide, determine, expect, fail, hope, learn, intend, manage, offer, plan, promise, refuse, want, wish等 I don’t want _____ like I’m speaking ill of anybody, but the manager’s plan is unfair.A.to sound B.to be sounded C.sounding D.to have sounded 当不定式短语比宾补长时,往往将不定式放到宾补后,而用先行代词it作形式宾语,常用动词有feel, think, find, believe, consider, make等。The cat felt it terrible to take roller coaster.b)不定式一般不作介词的宾语,只有少数介词如but, except等后面可以跟不定式作宾语。一般情况下作介词宾语的不定式都带to,如果but或except所在句子里的谓语动词都是实义动词do, does, did时,通常省略to。Eg.We have no choice but to wait.Cf.We can do nothing but wait.4.宾语补足语

在SVOC句型中,许多动词都可以按不定式作宾语补足语。

a)通常作宾语补语的不定式要带to,常用于以下动词之后:ask, tell, advise, allow, enable, expect, force, get, like, order, teach, want, invite, wish, beg等 You should get them to help you.但在谓语动词believe, find, think, feel, consider, suppose, imagine, prove等后面跟to be…作宾补,不跟to do…

eg.They believe him to be honest.b)以下两类动词后跟不定式作宾补时不能带to ①一些表示“致使”意义的动词,如:let, have, make等

②一些表示感觉的动词,如:hear, feel, see, watch, notice等 Don’t let the children trouble you.I heard someone open the door.但当这两类动词为被动态时,不定式就成了主补。作主补的不定式必须加上to His father made him go to bed early.→He was made to go to bed early by his father.5.作定语

不定式可以在句子充当后置定语,修饰名词。以下几类情况常用不定式作定语:

①能带不定式作宾语的动词,其同源名词可以带不定式作定语。常见的有attempt, decision, promise, plan等

eg.He hasn’t kept his promise to write to his parents regularly.②常与不定式搭配的形容词,其同源名词一般可以用不定式作定语。常见的有ability, determination, anxiety, eagerness等

eg.His eagerness to finish his homework was quite clear.③序数词形容词最高级或被only, last, next等修饰的名词可以用不定式作定语: She was the only person to survive after the earthquake.Tips: 不定式在作定语时,有时与被修饰的名词有意义上的主谓关系、同位关系、动宾关系,如果该不定式是不及物动词,它后面需要加上适当介词。Eg.He’s always the first to come and the last to leave.主谓关系

I’ve no time to listen to your excuse.同位关系

She has a meeting to attend.(动宾关系=attend a meeting)

There’s nothing to worry about.(动宾关系=worry about nothing)6.作状语

不定式可以作状语,表示目的、结果、原因、条件等。

①to…, in order to …, so as to …(不能放在句首)作目的状语

All these gifts must be mailed immediately _____ in time for Christmas.A.in order to have received B.in order to receive C.so as to be received D.so as to be receiving ②在so…as to, such….as to, only to …结构中不定式作结果状语,其中only to…用于表示意想不到的结果。

He hurried to the station only to find the train had gone.③enough to, too…to结构 eg.The boy isn’t old enough to go to school.= The boy is too young to go to school.④形容词(happy, glad, lucky, fortunate, surprised, angry, anxious, ready, quick, slow, cruel, clever等)+ 不定式结构 eg.I’m glad to meet you.The question is different to answer.He is hard to get along with.7.作插入语,用来说明说话人的态度、看法、对整个句子进行解释,如to be frank(坦白地说),to be sure(确实)等。Eg.To tell you the truth, I hate you.8.作同位语

eg.The order to start the general attack soon came.不定式的复合结构,以it为形式主语或形式宾语引导的复合结构,如果其前的形容词是指行为的性质就用:for sb.to do sth.这种复合结构在句中可作主语、表语、宾语、定语、状语等。

It is necessary for me to learn English well.如果该形容词是指行为的性质,同时又指行为的人,则用of sb.to do sth.。这种句式中的常用形容词有:right, wrong, brave, careful, careless, clever, wise, stupid, cruel, foolish, good, honest, kind, nice, silly等。

eg.It’s very kind of you to come to see me.连接代(副)词+不定式(包括whether, what, which, whom, where, when, how, 不包括why),在句中起名词的作用,通常跟在诸如tell, know, show, decide, learn, wonder, explain等动词后作宾、主语或表语。

Eg.No one can tell me where to find John.When to the exam is still unknown.The problem is how to get enough money.不定式的进行式、完成式和被动式

①不定式的进行式由to be + V-ing构成,用来表示谓语动词动作发生时,不定式的动作正在进行。

动词不定式中考考点全“透视” 篇3

◆具有动词的特点,因此,后面可以跟表语、宾语或状语,构成动词不定式短语。

◆具有名词、形容词或副词的特点,可以在句子中用作主语、宾语、宾语补足语、状语、定语、表语及同位语等。

下面以近年来各地中考典型试题为例,对动词不定式的难点及其在中考中的考查点,逐一作简要的总结和分析,供同学们学习时参考。

一、考查动词不定式的基本构成

[考点归纳]动词不定式由“不定式符号(to)+动词原形”构成。其否定式常在to 前加not或 never。 “ask/tell sb. (not) to do sth.”是各地命题的热点。

[中考题例]—My parents always tell meothers late at night.

—They’re right. It’s not polite. (2008年湖北恩施)

A. callB. not callC. to callD. not to call

[简析]本题属于比较容易的试题,考查的能级比较低。但是考生在应试时一定要小心,千万不能看到C项就误以为是正确答案。通读全题,领悟语境,才知道D项正确。

二、考查动词不定式作主语

[考点归纳]动词不定式作主语时,常用it作为形式主语,而将不定式后置。(该考点的具体内容可以阅读前文《点击动词不定式作主语时的五个注意点》)

[中考题例] It’s dangerous for you that tall tree. (2008年安徽芜湖)

A. climbB. to climbC. climbingD. climbed

[简析]该题属于识记类的试题,根据句型 “It’s + adj. + for sb. + to do sth.”可以快速得到正确答案B项。

三、考查动词不定式作宾语

[考点归纳]◆当动词不定式作宾语时,如后接宾语补足语,常用it 作形式宾语,而把真正的宾语(动词不定式)放在宾补之后,其句型为:“主语+谓语+it+宾语补足语+动词不定式(短语)”。

[中考题例] I find very important to learn English well because it is an international language now. (2008年甘肃嘉峪关)

A. itB. itsC. thatD. this

[简析]审读试题后可以知道,该题中的动词不定式(to learn English well)是真正的宾语,因此只能选择it作为形式宾语,故A项正确。

◆以动词不定式和动名词作宾语,意思存在差异的常考动词(组)是:

forget to do sth. 忘记去做某事forget doing sth. 忘记做过某事

remember to do sth. 记着去做某事remember doing sth. 记得做过某事

stop to do sth. 停下来去做另一件事stop doing sth. 停止正做的事情

go on to do sth. (做完一件事)继续做另一件事go on doing sth.继续做原来做的那件事

[中考题例] Last week I met my old friend Li Ming,but I forgot him for his telephone number. (2008年天津)

A. askB. asking C. and askD. to ask

[简析]审题后,结合题意,由but这一关键词可以知道,“我”忘记了问李明要他的电话号码,故应该使用 “forget to do sth.”这一结构,从而可以判断D项正确。

四、考查动词不定式作定语

[考点归纳] 动词不定式作定语时,常位于被修饰的词之后,与被修饰的词为逻辑上的主谓关系或动宾关系;如果不定式的动词是不及物动词,其后要加必要的介词或者副词,构成的短语动词相当于及物动词。

[中考题例] He is not an easy man . (2008年山东泰安)

A. get on B. to get on C. get on with D. to get on with

[简析]阅读完试题可以发现,空格处应该使用动词不定式作后置定语,由此排除A、C两项;get on是不及物动词短语,其后必须跟介词with,故D项正确。

五、考查动词不定式作状语

[考点归纳] ◆go, come, try one’s best等动词或动词短语作谓语时,其后常常接动词不定式作目的状语。

[中考题例] The doctor did what he could the dying man.

(2009年江苏宿迁)

A. saveB. to saveC. savedD. saving

[简析]这是一道经典试题,许多考生一看到试题中的 “could”就误以为其后应该接动词原形。其实,该题中从句(what he could)作主句中 “did”的宾语,空格处应该使用动词不定式作目的状语,故选B项。

◆“too+形容词/副词(for sb.) + to do sth.”和“enough (for sb.) + to do sth.”结构中,不定式作结果状语。

[中考题例] The house is too small for his family.(2008年四川资阳)

A. to live inB. living inC. live inD. lives in

[简析]发现该题中的 “too...to do sth...”这一关键信息,就可以快速得到正确答案A项。

六、考查动词不定式作宾语补足语

[考点归纳]有些动词,如teach, want, tell 等可接带to的不定式作宾语补足语,即构成 teach/want/tell sb. to do sth.的结构。 但是,动词不定式作使役动词和感官动词的宾语补足语时应省去to;在help后面作宾语补足语时,to可有可无。在初中阶段,具有类似用法的词可巧记为“一感(feel)、二听(listen to; hear)、三让(let; make; have)、 四看(look at; watch; see; notice)、半帮助(help)”。

注意:在主动语态中,这些动词后面跟省to的不定式;但是在变为被动语态时,要加上to。

[中考题例] The global financial crisis(金融危机) has made many people their money. (2009年江苏宿迁)

动词不定式教案和练习 篇4

教学目标:

1.掌握动词不定式的几种形式

2.掌握动词不定式在句子中可以作什成分

3.掌握动词不定式用法/功能 4.掌握运用动词不定式注意事项 教学难点:动词不定式用法

教学方法:通过放映幻灯片,教师讲解,学生思考,最后总结的方法来实现本课的教学任务。

教学过程:

Step1.出示幻灯片让学生了解动词不定式的几种形式 1.动词不定式的基本形式

 to + 动词原形

有时可以不带to(秃头不定式)2.动词不定式的否定形式 not/never + to do not/never + do 3.不定式的逻辑主语

It’s good for you to do morning exercises.The question is too difficult for us to answer.It’s too dark for me to see anything in the room.It’s very kind of you to think of the others.如果要说明不定式表示的动作是谁做的,可以在不定式前加一个for(of)引起的短语。介词for(of)的宾语叫不定式的逻辑主语。

Step2.请学生思考:动词不定式在句子中可以作什成分? 学生得出结论:

1.作 主语 2.作宾语

3.作宾语补足语 4.作定语 5.作状语 5.作状语 6.作表语

7.与疑问词等连用

Step3.出示幻灯片让学生根据总结结果加强记忆。Step4.讨论动词不定式用法/功能,并总结:(1).作主语

To see is to believe.It’s exciting to surf on the Internet

作主语的不定式如果很短,通常位于句首;若不定式(短语)较长时,常用it作形式主语,而把真正的主语(即动词不定式)放在后面以避免头重脚轻。(2)宾语

I want to go home.The workers decided to get better pay.I found it necessary to talk to him again.常用动词不定式作宾语的动词有: want, hope, wish, refuse, learn, would like, choose, decide, agree, pretend, expect, plan …

He found it very difficult to get to sleep 不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。感官动词和使役动词等后接不定式作宾补 时,需省to。但在被动语态中要还帽子。The boss makes them work 15 hours a day.I saw the accident happen yesterday.He was made to do his work(by me).(3).宾补

The teacher told me to clean the blackboard.I expect you to give me some help.He often helps me(to)repair my bike.常用动词不定式作宾补的动词有: tell, ask, want, warn, wish, allow, encourage, expect, teach, help(4).定语

I have something to say.He has a lot of homework to do.He is looking for a room to live in.There is nothing to worry about.动词不定式若在句中作定语,常放在被修 饰的名词或代词后。如果不定式中的动词 是不及物动词,则要带上与之搭配的介词,构成及物动词短语。(5)状语

He got up early to catch the train.Let’s stop to have a rest.I’m very happy to see you.He’s too young to go to school.She is old enough to dress herself 动词不定式作状语主要用来表示目的,原因,或结果等。(6).表语

My job is to help the patient.Your task is to clean the classroom.不定式可以放在be动词后,形成表语。(7)与疑问词连用

He didn’t know what to say.(宾语)

How to solve the problem is very important.(主语)

My question is when to start.(表语)不定式与疑问词who, which, when, how, what

等连用,形成带疑问词的不定式。在句中起名

词作用,可充当主语、表语、宾语等。

在与why连用时,只用于why或why not开头的简短疑问句中,后面紧跟的动词不定式不带to。

Why do sth.? Why not do sth.? Step5出示幻灯片让学生注意几个易错点。

1.有些动词既可跟不定式作宾语,也可跟动名词作宾语,但含义不同:

remember to do

记住要做某事;

remember doing 记得曾经做过某事

forget to do

忘记要做某事

forget doing

忘记曾经做过某事

stop to do

停下来去做某事

stop doing

停止做某事

go on to do

继续做另一件事

go on doing

继续做原来在做的事 I remember seeing you somewhere before.我记得以前在哪儿见过你。

Please remember to turn off the light when you leave.离开时请记得关好灯。I forgot to tell her about it.我忘记告诉她这件事。I forgot telling her about it.我忘记了曾把这件事告诉过她。

2.感官动词后既可跟不带to的不定式作宾补,也可跟v-ing作宾补,前者表示动作的全部过程已结束;后者表示动作正在进行。I saw him come downstairs.我看见他下了楼。(说明他下楼了这件事)I saw him coming downstairs.我看见他在下楼。(说明他下楼时的情景)I heard someone calling me.I heard my name called.Step6.通过练习来加强学生对本课知识的掌握。

Fill in each blank with the proper word from the brackets: 1.Mike wants ________(go)to a park on Sunday.2.The teacher often tells us ___________(not be)late.3.My brother is too young ________(join)the army.4.It takes me an hour _____(do)my homework every day.5.Do you have anything _________(say)?

“动词不定式”的自述 篇5

认识我就从记住我的“长相”开始吧:我是由“to+动词原形”组成的,to是我的标志,虽然to无实义,但它却是我的“铁杆”,一般情况下,我和它形影不离。我出入于句首、句中、句末,充当句子的各种成份(谓语除外),从而使句子变得更加丰富多彩。

我的“基本个性”:我“为人随和”,没有人称和数的变化,例如to live。否定形式在to前加not,例如not to spit in public places。我具有动词的特点,可以有自己的状语,如是及物动词还可带宾语,一起构成“不定式短语”,例如to study English well。

我的“真实本领”:我虽不能作谓语,但具有名词、形容词和副词的特征,在句中可以作“主语、宾语、表语、定语、状语、补语”,本领可大了!今天在此向同学们露几招,展示一下我的风采,你们可要认真学习啰!

一、作宾语:我天生讨“人”喜爱,下列及物动词都抢着让我“作宾语”,如want, decide, refuse, afford, hope, wish, expect, plan, remember, forget, would like等等。例如:

1) We have planned to travel to Hainan next week.

2) He never refuses to help others.

特别点击:在复合宾语结构中常用it作形式宾语,而真正的宾语则由我来担任,例如:I find it interesting to play chess.

二、作宾语补足语:我“助人为乐”,常来补充说明宾语“大有作为”,但“to”不能“随心所欲”。

1. 当谓语动词是ask, tell, want, teach, show, invite, encourage, allow时,to请“上座”,例如:

1) Lin Tao invited Jim to have dinner on Mid-Autumn Day.

2) My teacher always encourages me to work hard.

2. 当谓语动词是一“感”(feel)二“听”(hear, listen to)三“使”(make, have, let)和四“看”(see, watch, notice, look at)时,to会“让座”(省略to),但变成被动语态后,to不能省略,例如:

We often hear her sing in English. → She is often heard to sing in English by us.

三、作状语:我“服务热情”,常在come, laugh, cry, go, run, stop等不及物动词后作状语,说明的内容“各有千秋”。

1. 说明动作的“目的”。例如:

When I saw the wallet on the ground, I stopped to pick it up.

2. 说明动作的“原因”。例如:

We sang and danced to hear the good news.

3. 说明动作的“结果”。例如:

He worked hard to catch up with the others in his class.

特别提醒:

1. 下列句型中我“作状语”,须牢记在心头:

1) too+adj./adv.+to do sth.和adj./adv.+enough+to do sth.中我作结果状语。如:

The boy is too young to go to school.

2) be+adj.+to do sth.中我作原因状语。如:

I’m sorry to hear that you haven’t passed the exam.

2. 我有时修饰整个句子。例如:

He started the Cousteau Society to help protect life in the sea.

四、作定语:我“要求严格”,常来修饰名词或代词作定语并“后置”。例如:

1) I have lots of work to do.

2) I would like something to eat.

在逻辑上,我和被修饰的词是动宾关系,如果是不及物动词,则请“介词先生”助一臂之力。试比较:

1) I have a letter to write. (vt.)

2) I have no pen to write with. (vi.)

五、与疑问词连用:作tell, know, show, teach, decide, learn等及物动词的宾语,可改成由这些疑问词引导的宾语从句。例如:

Mr. Zhou showed us how to play the computer.

动词不定式中考要点展示 篇6

要点说明:在动词want, hope, would like, decide, wish, choose, expect, prefer等后常用动词不定式作宾语。而在动词enjoy, keep, finish, mind, feellike等后只可用动名词作宾语。另外,在be busy, be worth等后也应用v-ing形式。

中考真题:

1. When people want to relax themselves, they prefer ____ TV or listen

to music rather than ____ newspapers.(2006山东省临沂市)

A. watching; readB. watching; to read

2. Sam enjoys ____ stamps. And now he has 226 of them. (2006北京市)

A. to collectB. collectedC. collectsD. collecting

解析:在enjoy后应跟v-ing形式作宾语。D为正确答案。

3. He found it hard ____ his class. (2003新疆)

A. to catch up withB. to catch up

C. catch up withD. catch up

解析:这里应用动词不定式作宾语,因后面有hard作宾语补足语,故将动词不定式放在句子后面,而用it作形式宾语。A为正确答案。

要点展示二、动词不定式作宾语补足语

要点说明:在动词tell, want, would like, wish, ask等后常用动词不定式作宾语补足语。

中考真题:

1. The teacher asked those boys ____ too much noise in class.

(2006辽宁省沈阳市)

A. do not makeB. not makeC. not makingD. not to make

解析:ask后跟动词不定式作宾语补足语,D为正确答案。

2. The teacher told the boy ____ late again. (2003武汉市)

A. to not beB. not beC. not to be

解析:tell后应跟动词不定式作宾语补足语,且动词不定式的否定形式是在其符号to前加上not。C为正确答案。

要点展示三、动词不定式作主语

要点说明:动词不定式常可用作句子的主语,且常用it作形式主语,而将不定式放在句子后面。

中考真题:

1. It’s a good habit ____ breakfast every day. (2006陕西省)

A. hadB. haveC. hasD. to have

解析:此句用的是动词不定式作主语,但将该不定式放在后面,而用it作形式主语。答案为D。

2. People everywhere celebrate the New Year. ____ is a time to say goodbye to the past and to think about new beginnings.(2006山东省潍坊市)

A. ThatB. ItC. ThisD. Such

解析:后面的句子to say goodbye是动词不定式作主语,故前面用it作形式主语。答案为B。

要点展示四、不带to的动词不定式的用法

要点说明:在下面几种情况下动词不定式符号to应省略。

1)在情态动词后的动词不定式不可带to。

2)在had better后应跟不带to的动词不定式。

3)在Why (not)…?后应跟不带to的动词不定式。

4)在感观动词see, hear, watch, look at, listen to, feel, notice等以及使役动词make, let, have等后跟动词不定式作宾语补足语时应省去不定式符号to。

比较:在感观动词see, hear, find, watch, feel等后也常可用现在分词作宾语补足语,注意用动词不定式作宾语补足语和用动词现在分词作宾语补足语的不同用法:用现在分词作宾语补足语表示动词动作正在进行中,而用不带to的动词不定式作宾语补足语则仅表示曾有过该动作。

注意:将此类句型改为被动句时,省去的不定式符号to应加上。

5)在Will (Would) you please (not)…?句型中,please后应跟不带to的动词不定式。

中考真题:

1. Colours can change our moods and make us ____ happy or sad,

要点展示五、动词不定式作定语

要点说明:动词不定式作定语应放在被其修饰的词之后。注意:1)当作定语的动词不定式与其中心词之间存在着动宾关系时,该动词不定式应用及物动词或及物动词短语来构成,且其后不可再用人称代词宾格作宾语了。2)动词不定式作定语常表示一个尚未发生的动作,如动作正在进行则需用现在分词作定语,而动作若已完成(或动作具有被动意义时)则又需用过去分词作定语。注意三者的区别。

要点展示六、动词不定式与疑问词的连用

要点说明:动词不定式常可和what, where, when, how, which等疑问词连用,在句中充当某个成分。注意1)动词不定式和疑问副词连用时如果该不定式是由及物动词构成的,则该不定式应带有宾语。2)动词不定式和疑问代词连用时,如果该疑问代词是该动词不定式的逻辑宾语,则在不定式中的动词后不可再用代词作其宾语了,以避免重复。
