她的业余爱好是画画。

=Painting is her hobby. 2. Her duty is taking care of the babies.

照看婴儿是她的职责。

= ________________________________________________________________. 注意：不定式和v-ing 作表语的区别：

v-ing多表示一般行为和状态；

不定式则强调具体某次动作或将来要发生的动作。

v -ing形式作定语

1.单个动词的-ing形式作定语位于被修饰名词的___________，既可以表示被修饰者的作用或功能，也可以表示被修饰者的动作或状态。如：

building materials = materials for building

建筑材料

_________water = water for drinking

饮用水

a _________stick = a stick for walking

手杖

a __________room = a room for reading

阅览室

a ___________desk = a desk for writing

写字台

___________music = music that is tiring

烦人的音乐

a ____________result = a result that is surprising一个惊人的结果

2. -ing形式短语作定语时, 放在所修饰的名词____________, 并且在意思上相当于一个定语从句。如：

They lived in a room facing the street.

他们住在一间面朝街的房子。

= They lived in a room that faces the street.

The man standing there

is Peter’s father.站在那儿的那个人是彼得的父亲。

= The man __________________________________is Peter’s father.

3. -ing形式短语也可以用作非限制定语，相当于一个非限制性定语从句，这时，它与句子其他部分用逗号分开。如：

The apple tree, swaying gently in the breeze, had a good crop of fruit.

= The apple tree, which was swaying gently in the breeze, had a good crop of fruit. 那棵苹果树硕果累累，在微风中轻轻摇曳。

His brother, working as a teacher, lives in Beijing.

= His brother,

_____________________________________, lives in Beijing.

他那个当教师的哥哥住在北京。

v-ing形式作宾语补足语

1.动词-ing形式作宾语补足语常放在宾语后面，表示一个正在进行的主动性的动作，强调一个过程或一种状态。如：

When we returned to the school, we found a stranger standing at the entrance.

当我们回到学校时, 发现一个陌生人站在大门口。

We found the snake ____________ (eat) the eggs.

我们发现蛇正在吃鸡蛋。

I found a bag ____________ (lie) on the ground. 我发现地板上放着一个包。

The boss kept the workers___________(work) the whole night.

那老板让工人整夜地工作

2当主句转换为被动结构时, 原来作宾语补足语的动词-ing形式便转换为主语补足语。如：They found the result very satisfying.

这个结果很令人满意。

主语

宾语

宾补

= The result is found very satisfying.

主语

主补

They heard him singing in the next room.

有人听到他在隔壁房间唱歌。

= ____________________________________________________________ 3.能用v-ing形式作宾语补足语的几类动词:

1) 表示感觉和心理状态的动词，常见的有see, hear, feel, smell, find, notice, observe, look at, listen to等。如：

① We saw a light burning in the window.

② I felt somebody _____________(pat)me on the shoulder.

③ As he spoke, he observed everybody _________________(look at)him curiously. ④ Listen to the birds ______________.(sing) 注意：see, hear, feel, watch等动词之后用v-ing形式和省略to的动词不定式作宾语补足语的区别：

We passed by the classmates and saw the teacher making

the experiment.

我们走过教室，看见老师在做实验。

We sat an hour and watched the teacher make the experiment.

观察以上2个例句我们可以发现：

①前者表示动作________________，而后者表示（或强调）动作从开始到结束的______________. ②如果宾语补足语是短暂性动词，省略to的动词不定式短语表示一次动作，

而v-ing形式则表示反复动作。如：

We heard the door slam.

We heard the door slamming.

2）表示指使意义的动词，常见的有have, set, keep, get, catch, leave等。如：I won’t have you doing

that.

This set

me_______________(think). I’m sorry to have kept you________________ (wait).

I can’t get the clock ______________again (go). You won’t catch me _____________that again (do). Step IV【运用探究】
