2.______________________________________________________________

3._________________________________________________________

二、主要用法精讲

一、作用

1.  v.  -ing作定语起名词的作用, 表明被修饰名词的作用、用途等。表示“供……之用”, 相当于used for doing。

*building materials = _______________建筑材料

*a walking stick =_________________ 手杖

2.动词的ing形式作定语。名词与非谓语动词之间存有逻辑上的主动关系，并且一般都可以转化为一个进行时的定语从句。

 The meeting being held now is very important.现在正在举行的会议很重要。

→_____________________________________________________________.

【易错精点】

(1)表示正在进行的动作(变为从句时要用进行时态)。

*Tell the children playing there not to make so much noise. 

→_____________________________________________________________.. 

告诉在那儿玩的孩子不要发出这么大的噪音

*Did you see the man talking to the manager?

→_____________________________________________________________?

你看到那个和经理说话的人了吗?

(2)表示经常性的动作,  或现在 (或当时) 的状态(变为从句时,  用一般现在时)。

*The house standing at the corner of the street was built in 1955. 

→_____________________________________________________________. 

坐落在街角的那所房子是1955年建造的。

3.现在分词的主动式(doing)作定语，可表示主动和动作正在进行。

We met a group of pupils _______________________________________________________.

我们碰到了一群从学校回来的孩子。

4.现在分词被动形式 (being done) 可表示被动的、正在进行的动作。
