动名词

动名词

英语语法单词形式
动词ing形式的一种,兼有动词和名词特征的非限定动词。它可以支配宾语,也能被副词修饰。动名词有时态和语态的变化。动名词是非谓动词的又一种形式。动名词跟现在分词看起来完全一样,但如果去理解两者之间的差别,会很有帮助。动名词虽然看起来像动词,但作用上跟名词是一样的。[1]它在形式上与现在分词相同,都是在动词原形的词末加-ing。在现代语法中,这两种形式同视为"-ing形式"。这两种形式的另一个相同之处是:它们都是由动词变化而成的,它们都保留了动词的某些特征,它们都能带自己的宾语、状语,而构成动名词短语或是现在分词短语去担当句子成分。动名词一般式表示的动作通常是一般性动作,即不是明确地发生在过去、现在或将来的动作,或是与谓语动词所表示的动作同时发生的动作。

定义

英语中的动名词是由动词变化而来,它仍一方面保留着动词的某些特征,具有动词的某些变化形式,用以表达名词所不能表达的较为复杂的意念,另一方面动名词在句子的用法及功能与名词类同:在句子可以作主语、宾语、表语、定语。它也可以被副词修饰或者用来支配宾语。

例如:They run into constant discrimination in trying to find a job or friend.

在寻找工作和结交朋友方面,他们不断地受到歧视。

Living in digs means having one room in someone's house.

寄居的意思是在别人的家里借住一间房间。

附:动名词用法口诀:

动名词常泛指,句法作用宾/表/定与主,时态/语态之形式,一般/完成/被动式。Being done 系被动,不含任何进行意。用作主语请留意,常用it作形式主语,不指未来发生事,表达的信息系已知。用作表语请记清,作用相当一名词,检验方法很简单,主与表换位能成立。用作定语也易辩,表示名词之用途。用作宾语稍复杂,关键留意谓语动词(跟动名词作宾语的常用动词附后),时态同谓动作比较,先于谓动用完成式,其逻辑主语不固定,在句中/句外均有之。否定式其前加not,复合式其前加物主词,非句首宾格词也可用,尤其口语中更如此。

说明:1、主-----主语2、宾-----宾语3、表------表语4、定------定语5、谓动---谓语动词

常见题型

1)动名词做主语时,谓语动词为单数

2)在动名词和不定式中,作为介词的宾语是动名词

3)动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语

例:

I would appreciate_______ back this afternoon.

A.you to call B.you call C.you calling D.you’re calling(Key:C;换成your calling也对)

4)有些词后只能接动名词

admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can’t help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand...

5)另外还有一些接-ing形式的常用说法

it’s no good; it’s no/little/hardly any/ use; it’s not/hardly/scarcely use; it’s worthwhile; spend money/time; there’s no; there’s no point in; there’s nothing worse than; what’s the use/point...

6)有些词后面加不定式和动名词均可

remember, forget, try, stop, go on, cease, mean后面均可用不定式和-ing形式,但意义截然不容。

例:

remember to do/doing:

①I remembered to post the letters.(指未来/过去未来将要做的动作)

②I remembered posting/having posted the letters.(我记得做过这个动作)

forget与remember的用法类似。

regret的用法:

①I regret to inform you that…(我很遗憾地通知你……)

②I regretted having left the firm after twenty years.(为了“二十年前的离开”而遗憾。)

try to(努力)与try +–ing(试验):

①You really must try to overcome your shyness.

②Try practicing five hours a day.

易混辨别

动名词它在形式上与现在分词相同,都是在动词原形的词末加-ing。在现代语法中,这两种形式同视为"-ing形式"。这两种形式的另一个相同之处是:它们都是由动词变化而成的,它们都保留了动词的某些特征,它们都能带自己的宾语、状语,而构成动名词短语或是现在分词短语去担当句子成分。例如:

Speaking in the public,he will surely be very cheerful .

(现在分词短语,作状语)他在公众场所讲话时总是兴高采烈的。

She hates speaking in the public.

(动名词短语,作宾语)她不喜欢在公众场所讲话。

区别:

1.动名词和现在分词都可以用于系动词之后作表语,区别方法是:

①作表语的动名词与主语指的是同一件事,此时系动词相当于“是”,通常把主语和表语的位置互换,语法和意思不变,例如:

My hobby is swimming.可改为Swimming is my hobby.(可将原句中的主语与表语位置互换)

②现在分词作表语主要用以说明主语的性质,不能与主语互换位置,例如:

The story is interesting .不可改为:Interesting is the story.

2.动名词和现在分词都可以用作定语来修饰名词,两者的区别在于:

动名词修饰名词时主要表示该名词的用途,而现在分词修饰名词时性质、状态或动作等。试比较:

①a swimming boy和a swimming suit

前者的意思是“一个正在游泳的男孩”,即a boy who is swimming,现在分词swimming 表示被修饰名词boy的动作;而后者的意思是“游泳衣”,即a suit for swimming,动名词swimming表示suit 的用途。

②a sleeping child 和 a sleeping car

前者的意思是“一个正在睡觉的孩子”,即a child who is sleeping,现在分词sleeping 表示被修饰名词 child 正处于的状态;而后者的意思是“卧车(被用来睡觉的车厢)”,即 a car which is used for sleeping,动名词 sleeping 表示car 的用途。

特征

一、动名词可以保留原动词的各种用法,例如可以带宾语、表语、状语等。

例:They run into constant discrimination in trying to find a job or a friend.

在寻找工作和结交朋友方面,他们不断遇到歧视。

Living in digs means having one room in someone's house.

寄居的意思是在别人的家里借助一间房间。

二、动名词的动词特征还表现在它有时态和语态的变化。具体的变化形式如下:

主语语态

被动语态

一般式

V-ing

being+V-ed

完成式

having+V-ed

having been+V-ed

相关作用

动名词具有名词的性质,因此在句中可以作主语、表语、宾语、定语、补语、状语。

作主语

Reading is an art.读书是一种艺术。

Climbing mountains is really fun.爬山真是有趣。

Working in these conditions is not a pleasure but a suffer.在这种工作条件下工作不是一件愉快的事而是一件痛苦的事。

动名词作主语,谓语动词一般用三单形式

动名词作主语,在动词的基础上加Ing,使该动词或动词短语,有名词的各种特征,可作名词灵活使用。如:

It is no use/no good crying over spilt milk.复水难收

It is a waste of time persuading such a person to join us.劝说这样的人加入真是浪费时间。

It was hard getting on the crowded street car.上这种拥挤的车真难。

It is fun playing with children.和孩子们一起玩真好。

There is no joking about such matters.对这种事情不是开玩笑。

动名词作主语的几种类型

动名词可以在句子中充当名词所能充当的多种句子成分。在这里仅就动名词在句子中作主语的情况进行讨论。

动名词作主语有如下几种常见情况:

1.直接位于句首做 主语。例如:

Swimming is a good sport in summer.

2.用 it 作 形式主语,把动名词(真实主语)置于句尾作后置主语。

动名词做主语时,不太常用 it 作先行主语,多见于某些形容词及名词之后。例如:

It is no use telling him not to worry.

常见的能用于这种结构的形容词还有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。

注意:important,essential,necessary 等形容词不能用于上述结构。

3.用于“There be”结构中。例如:

There is no saying when he'll come.很难说他何时回来。

4.用于布告形式的省略结构中。例如:

No smoking ( =No smoking is allowed (here) ). (禁止吸烟)

No parking. (禁止停车)

5.动名词的复合结构作主语

当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构(——这时,名词或代词的所有格做动名词的逻辑主语)。动名词的复合结构也可以在句中作主语。例如:

Their coming to help was a great encouragement to us.

6.例词

shopping fishing cycling这些都是很常见的动名词

动名词作主语与动词不定式作主语的比较

动词不定式和动名词都可以用作主语。在意义上相近。但动名词多用来表示泛指或抽象动作,不定式多用来表示特指或具体动作。比较:

Smoking is not good for health.

It is not good for you to smoke so much.

注意:

1)在口语中,用动名词作主语位于句首的较不定式多见。

2)在“It is no use...”,“It is no good...”,“It is fun...”,“It is a waste of time...”等句型中,通常用动名词作真实主语:

It is no use/good/a waste of time talking about that.

*It is no use/good/a waste of time to talk about that.

3)在疑问句中,通常用动名词的复合结构,而不用不定式的复合结构作主语:

Does your saying that mean anything to him?

*Does for you to say that mean anything to him?

4)在“There be”句型中,只能用动名词,而不能用不定式作主语:

There is no telling what will happen.

It is impossible to tell what will happen.

5)当句子中的主语和表语都是非限定动词时,要遵循前后一致的原则,主语和表语在形式上要求统一:

Seeing is believing.

*To see is to believe.

作宾语

1.作动词的宾语

某些动词后出现非限定性动词时只能用动名词作宾语,不能用不定式。常见的此类动词有:

admit,appreciate,excuse,stand,advise,allow,permit,avoid,consider,enjoy,finish,give up,cannot help(can't help),imagine,include,keep,understand,keep on,mind,report,risk,miss,put off,delay,practise,resist,suggest,depend on,think about,set about,succeed in,worry about,burst out,insist on,feel like,be used to,get used to,devote…to…,look forward to,pay attention to,get down to,escape 等。如:

They went on walking and never stopped talking.

他们继续走,说个不停。

I found it pleasant walking along the seashore.

在海滩上走真是乐事。

Mark often attempts to escape being fined whenever he breaks traffic regulations.

每当马克违反交通规则时,他常常企图逃避罚款的处分。

有些动词之后既可接动词不定式,又可接动名词,可把这类动词分为三种类型:两种形式所表达的含义基本相同,可以互换。这类动词有:

attempt,begin,cease,continue,intend,omit,start,cannot bear,decline,disdain,loathe,neglect,commence。例如:

They ceased talking/to talk.

他们停止说话。

Prices will continue to rise/rising.

物价将继续上扬。

What do you intend to do/doing next?

你下一步打算干什么?

宾语用不定式和动名词所表达的含义略有变化。用不定式作宾语时,表示特定的一次性的未来动作;用动名词则表示一般的行为,或者是目前正在进行的行为。也可以说,动名词表示泛指的动作,而不定式表示特指的动作。常这样用的动词有:

hate,like,love,prefer,dread等。例如:

Woula you like to go with me?

你想跟我一起走吗?

He preferred to do this rather than do that.

他宁愿做这件事,而不愿做那件事。

2.作介词的宾语

动词+介词+动名词

例如:The rain prevented us from completing the work.

下雨妨碍我们完成工作。

She complains of the book being too difficult.

她抱怨这本书太难。

形容词+介词+动名词

例如:I know who is responsible for breaking the window.

我知道窗户是谁打破的。

名词+介词+动名词

例如:There are many ways of doing it.

有许多方法可以做这件事。

We are thinking of making a new plan for the next term.

我们正考虑为下学期制定新的计划。

Shall we have a rest or get down to doing our work?

我们休息呢还是开始干活?

there be和it is也可变为动名词there being 和it being与介词连用。

例如:The car stooped because of there being no fuel in the tank.

因为油箱里没有油,所以汽车停了下来。

介词+动名词也可在句中作状语,表示时间、条件等。

例如:On leaving school,he went into business.

一离开学校,他就投身到商业中去了。

3.作形容词的宾语

The music is well worth listening to more than once. 这种曲子很值得多听几遍。

We are busy preparing for the coming sports meet. 我们正为马上到来的运动会忙着做准备。

作表语

动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。表语动名词与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。如果句中的主语和表语同为动词时,要注意保持两个动词在形式上的一致。

例:

Your task is cleaning the windows.

你的任务就是擦窗户。(Cleaning the windows is your task.)

What I hate most is being laughed at.

我最痛恨的就是被别人嘲笑。(Being laughed at is what I hate most.)

The most popular pastime is playing chess.

最大众化的消遣是下棋(The most popular pastime is to play chess.)

作定语

动名词作定语往往表示被修饰词的某种用途。如:

a walking stick =a stick for walking=a stick which is used for walking

a washing machine=a machine for washing=a machine which is used for washing

a reading room=a room for reading=a room which is used for reading

a measuring tape=a tape for measuring=a tape which is used for measuring

sleeping pills=pills for sleeping=pills which is used for sleeping

三种用词

1)作主语。例如:

2)作宾语

a.有些动词可以用动名词作宾语。例如:

admit承认 appreciate感激 avoid避免 complete完成 consider认 delay耽误

deny否认 detest讨厌 endure忍受 enjoy喜欢 escape逃脱 fancy想象

finish完成 imagine想象 mind介意 miss想念 postpone推迟 practice训练

recall回忆 resent讨厌 resume继续 resist抵抗 risk冒险 suggest建议

face面对 include包括 stand忍受 understand理解 forgive宽恕 keep继续

例如:Would you mind turning down your radio a little, please? 你把收音机音量调小一点,好吗

The squirrel was lucky that it just missed being caught. 这松鼠幸运得很,刚逃避了被逮住的厄运。

b.有些结构后面可以用动名词作宾语或其他成分。例如:

stick to no good no use be fond of look forward to be proud of

be busy can't help be tired of be capable of be afraid of think of

burst out keep on insist on count on set about

put off be good at take up give up be successful in

3)作表语,对主语说明、解释。例如:

比较:She is washing, cleaning and taking care of the children.

4)作定语,一般表示所修饰名词事物的用途。例如:
