The –ing form as the Subject and Object

动词-ing形式

1. 构成: 在动词末尾加-ing 。

否定形式: not+ -ing 构成

2. 动词-ing形式不能单独作谓语, 没有人称和数的变化, 但可以有自己的宾语和状语, 还有时态和语态的变化。

3. 动词-ing形式由动词加-ing变化而成,

它同时具有名词和动词的特征, 在句中可以作主语、宾语等。

作主语

1. 表示经常的、习惯性的动作或状态,

谓语动词通常用单数。如：

Walking is a good form of exercise for

both young and old.

无论对年轻人和老年人来讲, 走路是一种

很好的锻炼。

Watching news on TV has become a

routine for me. 在电视上看新闻已经成了

我的一种日常习惯。

2. -ing形式作主语时常后置, 此时须用it 作形式主语, 用形容词或名词作表语。

常见的名词或名词短语有: no use,

no good, fun, hard work, a hard / difficult job, a waste of time 等; 形容词有: dangerous, worthwhile, useless等。如:

It’s no use making an excuse for this.

为这件事找借口是没有用的。

It’s dangerous swimming in the sea on windy days.

有风的天气在海里游泳是危险的。

3. 在there is no + Ving 的结构中如：

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。

注意

1、

动名词作主语表单数概念,谓语动词用单数形式。

Walking after supper is good for your health. 2、

动名词的复合结构作主语

动名词的复合结构是指物主代词、名词所有格是动名词逻辑上的主语、动名词是其逻辑上的谓语。

Your coming made us happy.

Your father’s cooking is very good.

动名词与不定式做主语时的比较：

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。

如：

还是个孩子的时侯, 她就觉得探视病人是

一种责任, 也是一种愉悦。

As a child, she felt that visiting sick people

was a duty and a pleasure．

Doing nothing is doing ill．

一直不做就是作恶。

He said, “To go on like this is useless .”

他说: “继续这样下去是无用的。”

It’s an honor for me to be invited to the party.

我很荣幸被邀请参加这个晚会。

常用-ing形式作主语的句型

•

It +be +a waste of time doing

做……是浪费时间的

•

It is/was no good/use doing

做……是没用处的

•

It is/was hardly/scarcely worth doing

做……不值得

•

It is/was worth/worthwhile doing

做……是值得的

•

There is no doing...

无法……; 不允许……

作宾语

1.只能后接动名词作宾语的动词, 常见的有

avoid, consider, enjoy, keep, finish, suggest, dislike, delay, escape, cannot help, imagine, mind, miss, practise, cannot stand等。

如：I can’t avoid going．

Have you considered looking for one special friend? We must try to avoid repeating the same mistake．

晚饭后你想和我一起散步吗? Do you feel like having a walk with me after supper?

人们忍不住嘲笑那个愚蠢的人。

People couldn’t help laughing foolish man．

这类动词还有: excuse, fancy, give up, put off, risk, insist on, look forward, feel like等。

注意

当

need, want, require, worth后面接动词-ing也可以表示被动。

Your hair wants cutting.

The floor requires washing.

That novel is not worth reading.

2. 既可接动名词又可接不定式作宾语的动词,

常见的有: begin, start, continue, like, love, prefer, by, mean, forget，remember, hate等。

在

like, love, hate, prefer等动词

之后，用-ing或不定式意义上没有什么不同, 只是侧重

点有些不同, 动名词表示泛指的动作, 不定式表示具体的一次性动作。

在

begin/start, continue之后, 用动名词和不定式, 意义无甚区别, 尤其是当主语是人的时候。

3. 动名词可与介词一起构成介词短语。

介词+动名词

如：

我们得想些法子改变人们的习惯。

We’ve got to think of ways of changing people’s habits.

我向你道歉, 刚才对你那样生气。

I apologize for being so angry with you. 离开几年之后再回到你的家乡, 感觉有点怪。

After being away for several years, it is a strange experience to return to the hometown.

动词+介词+动名词

如：

我坚持为这次出行带足需要的食物。

I insist on taking proper food for this trip．

同学们脸上没有笑容, 相反都做了怪脸。

Instead of smiling, each of them made a face 下列短语中的to都是介词, 所以后面跟名词或-ing形式: devote to, object to, pay attention to, get down to, lead to, look forward to, stick to, be used to等

I am looking forward to hearing from you soon.

我希望能尽快收到你的来信。

He devoted himself to creating a new super hydrid. 他致力于创造出一种新的超级水稻。
