having done having been done 动词-ing形式在句中的语法作用：动名词在句中作主语、宾语、表语和定语，现在分词在句中作状语、宾语补足语和定语。

Step 4. Presentation 一、动词-ing形式作主语

1．动词-ing形式作主语时，往往表示经常性、习惯性的动作，通常置于句首。

Reading aloud is a good way to learn a language. 大声朗读是学习语言的一种好方法。

Wasting a person’s time is the same as killing him for his property. 浪费别人的时间无异于谋财害命。

[名师点津]

(1)不定式作主语表示具体的或一次性的动作。

To lie to her is wrong. 对她撒谎不对。

(2)动名词作主语时，谓语动词用单数。

Climbing mountains is really difficult for the old. 对于老人来说爬山确实困难。

2．形式主语it代替动词-ing形式作主语。

此类句式常见的有：

It’s a waste of time doing sth.

做某事是浪费时间

It’s useless/worthwhile doing sth.

做某事没用/是值得的

It’s no good/use/fun doing sth.

做某事没好处/没用/没意思

It is no use waiting for other people to make decisions for you. 等别人替你做决定是没有用的。

It is a waste of time persuading such a person to join us. 劝说这种人加入我们是浪费时间。

3．当句型“There is no ...”表示“不允许、禁止某种行为的发生或存在”时，需用动词-ing形式作主语。

There is no denying that the environment is from bad to worse. 不能否认环境状况正在逐步恶化。

There is no joking about such matters. 这种事开不得玩笑。

二、动词-ing形式作宾语

1．作动词的宾语

He tried to avoid answering my questions. 他试图对我的问题避而不答。

2．作动词短语的宾语

常见的跟动词-ing形式作宾语的动词短语有：insist on,

object to, be good at, be fond of, lead to, put off, give up, look forward to, feel like, devote to, get/be used to, pay attention to, be worth等。

He insisted on doing it in his own way. 他坚持要按照自己的方法做。

3．在有些动词的后面，如：start, begin, continue等既可接动名词也可接不定式作宾语，两者意义区别不大。

They continued working/to work as if nothing had happened. 他们继续工作，似乎什么也没发生过。

4．在love, hate, prefer, like等动词后接动词-ing形式作宾语指经常性的动作，用不定式作宾语指具体的动作。

He preferred staying in the house when it rained. 下雨时他宁愿待在家里。(用动词-ing形式作宾语，指每逢天下雨都待在家里。) I prefer to stay at home this afternoon. 今天下午我宁愿留在家里。(用动词不定式作宾语，表示今天下午留在家里这一具体的动作。) 5．有些动词(短语)后跟不定式和动词-ing形式作宾语均可，但含义不同。常见的有：

三、动词-ing形式的否定形式

动词-ing形式的否定形式通常是在其前加not，带有逻辑主语时

not应放在逻辑主语和动词-ing形式之间。

You have no excuse for not going. 你没有理由不去。

He was punished for not having done his homework. 他因未完成作业而受到惩罚。

四、动词-ing形式的复合结构

动词-ing形式的复合结构由物主代词或人称代词宾格、名词所有格或普通格加动词-ing，即“sb./sb.’s＋doing”构成。动词-ing形式的复合结构实际上是给动词-ing形式加了一个逻辑主语。动词-ing形式的复合结构有四种形式：

①形容词性物主代词＋动词-ing ②名词’s＋动词-ing ③代词宾格＋动词-ing ④名词＋动词-ing 第
