Step4.Summing &chewing, summarizing knowledge总结反刍 ,知识梳理)

Grammar learning

一、概述

和不定式一样,动名词也是非谓语动词的一种,它通常由动词原形加-ing构成。动名词有主动和被动两种语态,有一般式,完成式和进行式三种形式。如下表所示:

主动

被动

一般式

doing

being done

完成式

having done

having been done

完成进行式

having been doing

动名词仍保留有动词的特征,可以和自己的逻辑主语、宾语和状语等构成动名词短语。动名词具有名词的功能,在句中可以充当主语、宾语、表语、定语等成分。

二、动名词的时态和语态形式

1.动名词的时态形式

一般式

动名词的一般式表示动作或状态与谓语动词的动作同时发生,或者表示一种无时间性限制的经常性、习惯性的动作或状态。

He enjoys writing letters in English.

他喜欢用英语写信。

Many young people like playing football.许多年轻人喜欢踢足球。

完成式

动名词的完成式表示动作或状态先于谓语动词的动作或状态,:

They regret having been unable to help you.他们为没能帮上你的忙而遗憾。

完成进行式

动名词的完成进行时表示动作发生于谓语动作之前,并一直持续到谓语动词的动作发生之时,或继续。如:

Forgive me for my having been interrupting you so much.原谅我打扰你这么久。

2.动名词的被动式

当动名词的逻辑主语是动名词动作的承受者时,用被动式。如:

He climbed through the window without being seen.他从窗口爬进去,没有被人发现。

She needs to work without being disturbed (=without people disturb her).

她要在无人干扰的情况下才能工作。

动名词的被动语态分成一般式和完成式两种。如:

The railway is in the process of being constructed.

铁路在兴建中。

三、动名词的否定式

动名词的否定式通常是在动名词前加否定词not。例如:

I apologize for my not having kept promise.

我没能遵守诺言,十分抱歉。

I regret not being able to help you.

我很抱歉不能帮助你。

 

 

Usage

Examples

 

在句首或在句末(it作形式主语)常用动名词形式作主语的句型有:

      It +be+ a waste of time doing sth ;…..是浪费时间的

it is /was no good/use doing sth  ;……是没有用处的

it is/ was hardly/ scarcely worth doing sth; …..是不吃的

it is/was worth/worthwhile doing sth  ; …..是值得的

There is/ was no point doing sth ……是无意义的

 there be结构中作主语,这种结构的意思相当于“It is impossible to do...”。例如:There is no hiding of evil but not to do it.

若要人不知,除非己莫为。

There is no joking about such matter

这种事开不得玩笑。

There was no knowing when he would leave.

无法知道他什么时候离开。

注意:动名词与不定式作主语时的比较:

动名词表示的动作通常是一个泛指的动作,不定式则通常表示具体的动作。例如:

As a child,she felt that visiting sick people was a duty and a pleasure.

还是个孩子的时候,她就觉得探视病人是一种责任,也是一种愉悦。

Being a guest in an American home will be a good experience for me.

到美国人家里做客对我来说将是一个极好的经历。

Doing nothing is doing ill.

什么也不做就是作恶。

There is/was nothing worse than doing 没有比……更糟的

There is/was no point doing ……无意义

 

(1)动名词直接置于句首主语的位置上。Learning new words is very important for me.

学习新单词对我来说非常重要。

Talking is easier than doing。说比做容易。

(2)用形式主语it,把真正的主语——动名词结构移置句尾。

It’s worth making the effort.

这事值得去做。

Is it any good trying to explain?想再解释一次有好处吗?

It is pleasant working with you.

跟你在一起工作是令人愉快的。

 

作宾语

在下列动词、短语后用动名词作宾语suggest  finish  stop  can’t help  mind  admit  enjoy  put off  delay   practise  consider  miss escape keep  ; insist on  be interested in  be afraid of  be fond of  be good at  dream of  feel like  prevent/keep/stop spend…in… get/be used to+n/pron  be proud of  be tired of  look forward to thank…for  excuse…for succeed in  depend on be suitable for  give up  put off be busy(in)doing sth  pay attention to  object to devote…to… contribute…to owing to lead to

1)下列动词后接动名词和不定式均可作宾语:attempt begin/start continue  intend   

2)下列动词后接动名词和不定式作宾语意义不同:remember/regret/ forget to do, remember/regret/forget doing sth ; stop to do sth, stop doing sth; mean to do sth,

mean doing sth; allow/permit/advise/forbid/  doing sth, allow/ permit/ advise/ forbid /recommend sb to do sth;need/want/require doing sth需要被……need/ want/ require to do sth 需要….
