Body languageGrammar 一、V-ing 形式由 “do＋ing” 构成, 其否定形式是 “not doing”, V-ing可以带宾语或状语构成V-ing短语, 没有人称和数的变化, 但有时态和语态的变化。V-ing 形式(not) doing(not) being done(not)
having done(not)
having been doneV-ing形式在句中作定语和状语是本单元的学习重点。1. 作定语
V-ing形式可以单独充当名词的前置修饰语, 这时有两种情况。
-ing形式表示 “供作......之用”的意思, 这类作定语的-ing形式，叫动名词。
e.g. a swimming pool
= a pool for swimminga sleeping car= a car for sleeping2) -ing形式表示 “......的” 意思, 叫现在分词。
e.g. a sleeping child
working people
the rising sun -ing形式短语作定语时一般放在它所修饰的名词之后, 相当于一个定语从句。
e.g. They are visitors coming from
several countries.
The boy standing there is a classmate
of mine.2. 作状语
可以表示时间, 原因, 结果, 条件, 行为方式或伴随动作等。1) Using your head, you’ll find a good
way.条件2) Four people entered the room looking around in a curious way.
= Four people enter the room and looked around in a curious way.
伴随动作
3) Being poor, he couldn’t afford a TV set. 原因4) He came running back to tell me
the news. 方式5) (When) Hearing the news, he got
frightened.
= When he heard the news, he got frightened.
时间, 可以在分词前保留when 6) The child slipped and fell, hitting
his head against the door. 结果Attention-ing形式作状语时, 它的逻辑主语必须与主句的主语是一致的。e.g. Time permitting, I will pay a visit
to the whole city.
　(分词的逻辑主语是time, 而句子的主语是I, 两者不构成主谓关系, 所以只能用独立主格结构, 也就是给现在分词补充一个主语。)e.g.
I waiting for the bus, a bird fell on my heard.
我等汽车时，一只鸟落到我头上。
All the tickets having been sold out, they went away disappointedly.
所有的票已经卖光了，他们失望地离开了。
Time permitting, we’ll do another two exercises.

asleep.
