篇3：非谓语动词——动词不定式

动词不定式的基本形式是“to+动词原形”,有时不能带to。它没有人称和数的变化,在句子中不能作谓语,但它具有名词、形容词、副词的特征,在句子中可以作主语、宾语、宾语补足语、表语、定语和状语,它可以有自己的宾语和状语,并和其一起构成不定式短语,不定式的否定形式是在to前加not。

Please tell Tom to come here on time tomorrow.

The doctor asked her not to eat too much meat.

一、不定式作主语

To keep the environment clean is our duty.

在日常英语中,特别是当主语较长而谓语较短时,常用it作形式主语,而把真正的主语——动词不定式放在句子后面,避免头重脚轻。

It is good for our health to drink more water every day.

二、不定式作宾语

常用在及物动词want,begin,decide,forget,hope, like,learn等的后面。

I want to buy a computer.

He decided to give up smoking.

不定式后面有宾语补足语时,可用先行词it作形式宾语,把真正的不定式宾语后置。动词后能接复合宾语的有: think, find, believe, suppose, make等。由于宾语和宾补有逻辑上的主谓关系,所以有时候将宾语和宾补换成从句的形式。

He found it difficult to learn English well.

=He found that it’s difficult to learn English well.

三、不定式作宾语补足语

1.动词 ask,tell,want,teach,allow等后跟带to的动词不定式作宾补。

The teacher asked us to do Exercise 1.

The policeman told the children not to play football in the street.

2.使役动词(let,make,have)和感官动词(feel,see, watch,notice,hear)后跟不带to的不定式。

The boss made the workers work twelve hours a day.

感官动词后既可跟不定式也可跟现在分词,它们的区别是:用不定式表示动作的全过程或经常性、习惯性的动作:用现在分词表示当时正在进行的动作。

I saw the boy climb the wall.(我看见小孩爬墙了)

I saw the boy climbing the wall.(我看见小孩在爬墙)

3.不带to的不定式在被动结构中,必须带上to。

She is often heard to sing in the next room.

The boy was made to stand in the classroom.

四、不定式作表语

一般紧跟在be,get,seem等系动词的后面,用于说明主语。

My wish is to be a doctor.

The maths teacher seemed to be angry.

五、不定式作定语

不定式作定语时与所修饰的名词或复合不定式有逻辑上的主谓关系或动宾关系,要放在所修饰的词后面。

I have a lot of things to do today.

He needs some paper to write on.

六、不定式作状语

动词不定式具有副词的功能,修饰动词、形容词和副词,用作目的、原因、结果、条件等状语。当表示目的时,为了更突出,可将不定式放在前面。

They will go to the station to meet the guests.

To catch the early bus, he got up early.

七、不定式和疑问词连用

该结构在句中可作主语、宾语、表语等。

He didn’t tell me what to do next.

He didn’t tell me how to do it.

篇4：动词不定式要点点拨

1. 作主语，如：

To see is to believe.眼见为实。

不定式作主语，往往用it作形式主语，真正的主语（不定式结构）放在句子的后面。如：

It?蒺s necessary to lock the car when you do not use it.不用车的时候，有必要把它锁上。

2. 作表语，如：

The important thing is to save lives.救人要紧。

3. 作宾语，如：

They demanded to be shown the authentic documents.他们要求拿出可信的证据。

4. 作定语，不定式作定语通常放在被修饰的词后，往往表示未发生的动作，如：

The new term is coming and I have a lot of work to do. 新学期到了，我有许多事要做。

此外，不定式还可用来修饰被序数词、最高级形容词或no， all， any等限定的中心词。如：

She was the first woman to win the gold medal in the Olympic Games.她是第一位在奥林匹克竞赛中获得金牌的女士。

He was the best man to do the job.他是最适合做这项工作的人。

（1） 作定语的不定式如果是不及物动词，不定式后须有相应的介词。如：

There is nothing to worry about. 没什么好担心的。

Please give me a knife to cut with. 请给我一把切东西的刀。

但如不定式修饰的名词是time， place或way时，不定式后的介词通常省略。如：

We are looking for a place to eat. 我们正在找一个吃饭的地方。

I have no time to wait. 我没有时间等。

（2） have sth. to do 与have sth. to be done 的区别，如：

I have a lot of things to buy. （to buy动作的执行者是主语I）

Do you have anything to be bought?（to be bought动作的执行者不是主语you而是问话者）

5. 作状语，不定式可作目的状语、结果状语、原因状语、条件状语等。

（1） 作目的状语。常用结构为to do， only to do（仅仅为了）， in order to do， so as to do， so（such）...as to...（如此……以便……， 通常不用于句首）。如：

He ran so fast as to catch the first bus.他飞快地跑着以便赶上第一班车。

I come here only to say goodbye to you.我来仅仅是向你告别的。

（2） 作结果状语（常可以表示没有预料到的或事与愿违的结果，不定式要放在句子后面）。如：

I awoke to find my trunk gone.我醒来发现箱子不见了。

He searched the room only to find nothing.他搜查了房间，没发现什么。

（3） 作原因状语，如：

I?蒺m glad to see you. 见到你很高兴。

She wept to see the sight. 她一看到这情形就哭了。

（4） 作条件状语，如：

He must be a fool to say so. （= He must be a fool if he says so.）只有傻瓜才这么说（如果他这么说，他一定是个傻瓜）。

You will do well to speak more carefully. （= You will do well if you speak more carefully.）你要是说话能更注意点就好了。

6. 作补语

下列动词后常跟不定式作宾语补足语：

advise; allow; cause; challenge; command; compel; drive（驱使）; enable; encourage; forbid; force; impel; induce; instruct; invite; like/love; order; permit; make; let; have; want; get; warn; persuade; request; send; tell; train; urge等。

如：

I want you to be happy.我要你幸福。

I would like you to have an opportunity to appreciate Chinese art.我想给你一个欣赏中国艺术的机会。

下列动词后作宾补的动词往往是be：

consider; find; believe; think; declare（声称）; appoint; prove; suppose; feel; understand; imagine; know; guess; fancy（设想）; guess; judge等。

如：

I know this to be a fact. 我知道这是事实。

We believe him to be guilty. 我们相信他是有罪的。

We know him to be a fool. 我们知道他是个笨蛋。

I consider him to be too lazy. 我看他太懒了。

在consider， believe， declare， find， prove， think， imagine等之后，to be常可省去（包括在被动结构中）。如：

We believe him （to be） guilty.

He was considered （to be） too lazy.

1. 情态动词之后。

2. 使役动词 let， have， make；感官动词 see， watch， look at， notice， observe， hear， listen to， smell， feel， find 等后作宾补的不定式（注意：被动语态中不能省略 “to”）。如：

The boss made them work the whole night. 老板让他们整夜干活。

被动式： They were made to work the whole night.

3. would rather，had better后。

4. Why.../Why not...句型后。

5. help 后不定式可带to，也可不带to：help （sb.） （to） do sth.。

6. but和except前有实义动词do时，后面出现的不定式不带to。

比较：

He wants to do nothing but go out.他只想出去玩。

He wants to believe anything but to take the medicine.除了吃这药，他什么都信。

7. 由and， or和than连接的两个不定式，第二个to 可以省去。

8. 通常在discover， imagine， suppose， think等词后作宾语补足语时，可以省去to be。如：

He is supposed （to be） nice.他应该是个好人。

“疑问词＋不定式”结构在句子中起名词的作用，可作主语、表语、宾语。如：

When to start has not been decided. 何时开始还没有决定。（不定式作主语）

I asked him how to learn English. 我问他如何学英语。（不定式作宾语）

He didn’t know whether to go there or not. 他不知道是否去那儿。（不定式作宾语）

The question was where to go. 问题是去哪儿。 （不定式作表语）

1. 主要有：

forget to do sth. 忘记去做某事（未做）forget doing sth. 忘记做过了某事（已做）

remember to do sth.记住去做某事remember doing sth.记得曾做过某事

stop to do sth.停下来去做另一件事stop doing sth.停止做某事

try to do sth.努力/试图做某事try doing sth.尝试着做某事

go on to do sth.（做完某事）接着做另一件事go on doing sth.继续做某事 （同一件事）

can’t help to do sth.不能帮助做某事can’t help doing sth.情不自禁地做某事

mean to do sth.打算做某事mean doing sth.意味着做某事

regret to do sth.遗憾地去做某事regret doing sth.后悔做了某事

2. 动词like， love， prefer后接动名词时表示是经常性的动作行为；若要表示具体的行为则常用动词不定式。如：

I like swimming， but I don’t like to swim this afternoon. 我喜欢游泳，但是今天下午我不想去游泳。

3. 动名词的主动形式表被动意义。动词need， require， want表“需要”，deserve表“值得”时，常用动名词的主动形式表示被动意义。

needrequirewantdeservedoing =needrequirewantdeserveto be done

如：

The window needs cleaning. （= needs to be cleaned.）

1. —The last one _______ pays the meal.

篇6：动词不定式的用法

I am very glad to hear it.

The question is difficult to answer.

“too + 形容词或副词 + 不定式”作状语。如：

He is too old to do that.

另外，句子中有enough这个词时，常用不定式作状语。例如：

The room is big enough to hold us.

6)作表语。如：

My job is to help the patient.

7)作独立成分。如：

To tell the truth, I don’t agree with you.

8)不定式与疑问词who，which，when，where，how，what等连用，在句中起名词作用，可充当主语、表语、宾语等。如：

He didn’t know what to say. (宾语)

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

注意：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。例如：

Why not have a rest ?

9)不定式在句中用主动式还是被动式，多数情况下是容易判断的，但有时的确比较复杂，请注意以下几点：

①不定式修饰的名词或代词和不定式逻辑上构成主谓关系时，不定式往往用主动形式。如：

Have you got a key to unlock the door ?

(A key unlocks the door. )

②不定式和它前面被修饰的名词或代词构成逻辑上的动宾关系，又和该句主语构成逻辑上的主谓关系时，不定式常用主动形式。

I have got a letter to write. (I write letter. )

He needs a room to live in. (He lives in a room. )

I know what to do. (I do what. )

但这句如改为下列形式，不定式就得用被动形式：I know what is to be done.

这是因为what is to be done是宾语从句，从句中的主语what是动词do的动作对象。

③不定式作表语形容词的状语，和句中主语构成逻辑上的动宾关系时，不定式多用主动形式，这是因为人们往往认为形容词后省去了for sb. 。如：

He is hard to talk to. (to talk to him)

The book is difficult to understand. (to understand the book)

④在there be结构中，当说话人考虑的是必须有人去完成某件事时，不定式用主动形式;如果说话人强调的事情本身必须完成，则用被动形式。

There is a lot of work to do. (Somebody has to do the work. )

There is a lot of work to be done. (The work has to be done. )

请注意下面两个句子的含义是不同的：

There is nothing to do. (无事可做，感到十分乏味。)

There is nothing to be done. (某东西坏了，无法使之恢复正常。)

2.不定式的时态

1)不定式的一般形式所表示的动作，通常与谓语的动作(状态)同时(或几乎同时)发生，或是在它之后发生。例如：

I saw him go out.

2)如果谓语表示的动作(情况)发生时，不定式表示的动作正在进行，这时不定式就要用进行式。例如：

He pretended to be reading a book when she went in.

3)如果不定式的动作发生在谓语动词之前，就要用完成式。例如：

I’m sorry to have kept you waiting.

3.不定式的语态

当不定式逻辑上的主语是这个不定式所表示的动作的承受者时，不定式一般要用被动形式。如：

He asked to be sent to work in the countryside.

It is possible for our hopes to be realized.

4.不定式符号to的保留问题

有时为了避免重复，可以用to来代替前面的不定式，这种情况常出现下列动词后：expect，prefer，care，mean，forget，want，wish，hope，try以及be glad/happy等后。

如果在省略的不定式结构中含有be，have，have been，这些词要保留。如：

―Are you on holidays ?

―No, but I’d like to be.

―I didn’t tell him the news.

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。
