2.

它同时具有动词和名词的作用，在句子可充当主语、宾语、表语、定语、状语、补语。

3.

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.

Watching news on TV has become a routine for me.

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。

It is/was + n./adj. + doing

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.

It’s a waste of time talking about such a useless thing.

It is worthwhile discussing the question.

3）在there be 结构中作主语, 这种结构的意思相当于“不可以，不能，不... ”。如：

There is no joking about such matter. There was no knowing when he would leave.

4.

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．

1

Have you considered looking for one special friend? 2)当

need, want, require, worth后面接动词-ing表被动。

The floor requires washing.

The floor requires to be washed. That novel is well worth reading.

注意：1. 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。

2.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。

3. 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。

4. 在动词forget, remember, regret之后, 用动名词与不定式意义不同。动名词表示动作先于谓语发生,不定式表示后于谓语动作。如：

I remember posting the letter．

I’ll remember to post the letter．

I shall never forget seeing the famous writer．

5.在try, mean 之后, 意义各不相同, 如

try to do (设法), try doing (试试), mean to do (打算, 有意要做), mean doing (意思是, 意味着)。

如:We must try t o get everything done in time．

Let’s try doing the working in some other way．

I didn’t mean to make you angry．

Your plan would mean spending hours．

6.go on doing 继续做一直在做的事; go on to do 接着做另一件事。如：

Please go on doing the same exercise．

Please go on to do the other exercise．

7. stop doing 与

stop to do: Stop doing 停止做，

stop to do停下正在干的事去干另一件事。如: We stopped talking．

We stopped to talk．

3）

动名词可与介词一起构成介词短语。介词+动名词

如：

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

I apologize for being so angry with you. After being away for several years, it is a strange experience to return to the hometown. Step III
