1.动词-ing形式作表语
动名词作表语表示抽象的、一般的行为，现在分词作表语表示主语的特征、性质和状态。

Our greatest happiness is serving the people.（动名词）
Our task is building socialism. （动名词）
The film we saw last night is quite moving. （现在分词）
His words are encouraging. （现在分词）
注:常用来作表语的现在分词有astonishing, amusing, confusing, disappointing, boring, encouraging, inspiring, moving, tiring, interesting, surprising等。

提示：
（1）动名词作表语和主语是等值关系，两者有时可以互换，句子意思不变；动名词后面可以接宾语、状语。

（2）现在分词作表语和主语不是对等关系，现在分词后面不能接宾语，但它前面可以有修饰性的副词，如very, rather等。

2. 动词-ing形式作定语
动名词作定语用来说明该名词的用途，不表示名词本身的动作；现在分词作定语与所修饰的名词具有逻辑上的主谓关系，即现在分词相当于所修饰名词的谓语。

We must improve our working method. （动名词）
They set up an operating table in a small temple.（动名词）
China is a developing country. （现在分词）
The student making the experiment is our monitor.（现在分词）
提示：
(1)动名词短语不能作定语，单个的动名词可以用作定语，但仅作前置定语。

如working method=method for working 工作方法
(2)单个分词和分词短语都可作定语，单个分词一般作前置定语，分词短语则作后置定语，相当于一个定语从句。

如：the man visiting Japan=the man who is visiting Japan 访日的那个人。

3.动词-ing形式作宾补
动名词不能作宾语补足语。

现在分词作宾补表示的是正在发生的动作。

例如：
I saw him going upstairs.
We watched her crossing the street.
I saw a man sliding on a banana skin, and I laughed a lot.
He saw a man stealing into the small room.
提示：接现在分析作宾语补足语的动词有feel, hear, listen to, see, look at, watch, observe, notice, find, smell, set, have, keep, start, leave, get catch等。
