语法讲解
非谓语动词中的ing形式包括两种：
一种是动名词，另外一种是现在分词。
• 基本形式：
1、-ing形式作表语
1) -ing形式作表语时放在系动词之后，用来泛指某种动作或行为，以说明主语的具体内容(身份、性质或情况)。如：
Her hobby is painting. 她的业余爱好是画画。
My job is looking after the children. 我的工作就是照顾这些孩子。
2) –ing用来表示主语所具有的特征，如：
His concern for his mother is most touching. 他对母亲的关爱很感人。
His words are encouraging. 他的话很鼓舞人。

1) 单个-ing形式作定语时, 放在所修饰的名词之前, -ing形式短语作定语时, 放在所修饰的名词之后, 并且在意思上相当于一个定语从句。如：

他们住在一间面朝街的房子。
The man standing there is Peter’s father. = The man who is standing there is Peter’s father.
站在那儿的那个人是彼得的父亲。
2) V-ing, 过去分词，不定式做定语时的区别：
The student making the experiment is our monitor. They lived in a room facing the street.
正在举行的会议非常重要。 The meeting being held now is very important.
昨天举行的会议非常重要。 The meeting held yesterday is very important.
明天要举行的会议非常重要。 The meeting to be held tomorrow is very important.
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：
His brother, working as a teacher, lives in Beijing. = His brother, who is working as a teacher, lives in Beijing.
他那个当教师的哥哥住在北京。

3、奶蛇-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，强调一个正在进行的动作或一种状态。如：
当我们回到学校时, 发现一个陌生人站在大门口。
When we returned to the school, we found a stranger standing at the entrance.
我发现地板上放着一个包。 I found a bag lying on the ground.
那老板让工人整夜地工作。 The boss kept the workers working the whole night.
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：
后羿台词They found the result very satisfying. = The result is found very satisfying.
They heard him singing in the next room. = He was heard singing in the next room.
3). 能用-ing形式作宾语补足语的几类动词:
a. 感官动词，常见的有e, hear, feel, smell, find, notice, obrve, 等。如：
1.We saw a light burning in the window. 2.I felt somebody patting me on the shoulder.
对公司的寄语
3.Can you smell anything burning? 4.As he spoke, he obrved everybody looking at him curiously.
5.Listen to the birds singing. 6.I didn’t notice him waiting.

3.I’m sorry to have kept you waiting. 4.I can’t get the clock going again.
5.似火骄阳You won’t catch me doing that again.
4) e, hear, feel, watch等动词之后用-ing形式和动词不定式作宾语补足语的区别：
① 前者表示动作正在进行，而后者表示（或强调）动作从开始到结束的全过程。如:
1.We pasd by the classmates and saw the teacher making the experiment. 我们走过教室，看见老师在做实验。
（只在走过教室的刹那间，看见老师正在做实验）
个人核心价值观 2.We sat an hour and watched the teacher make the experiment. 我们坐了一个小时，看老师做实验。
（一个小时之内一直在看老师作实验）
② 如果宾语补足语是短暂性动词，动词不定式短语表示一次动作， 而-ing形式则表示反复动作。如：
1.We heard the door slam. (一次动作) 2. We heard the door slamming. (反复动作)
