Grammar-- -ing Form
Revising the use of –ing forms of the verbs and make Ss grasp the use of it.
I. v+ing 的句法功能：
1.作主语。可直接作主语， 表示一般抽象概念时，可以与不定式互换，但在句型“It is no use/good”等候一般用动名词。
e.g. It is no good smoking too much.
Seeing is believing.
2. 作宾语。有些动词可以直接跟v.-ing作宾语，
如：mind, miss, enjoy, escape, prevent, practice, postpone, suffer, suggest, keep(on), avoid, admit, bear, deny, advise, delay, risk, resist, finish, fancy, excuse, imagine, consider, can’t help,
下列 “vi.+介词或副词” 构成的短语动词，后接v.-ing作宾语。
succeed in, approve of, persevere in, inquire of, persist in, complain of, insist on, aim at, benefit from, burst out, can not help, be busy (in), be on the point of, feel like, guard against, give up, go on , keep on, leave off, put off , be used to, object to, be accustomed to, refer to, be opposed to, stick to, be dedicated to, be devoted to ,look forward to, turn to, come near to, devote oneself to, due to, pay attention to, be faithful to ,be equal to, be familiar to, be sentenced to…
e.g. We enjoy learning English.
He insisted on seeing the exhibition.
I am looking forward to seeing you.
The mayor considered building a new town-hall.
3. 作表语。作表语表示主语的内容或表示状态，说明主语的特点（ 这是主语是v.-ing形式的执行者）。
e.g. Our aim is studying English well.
His speech is very exciting.
4. 作定语。 表示主动，相当于一个定语从句， 表示动作在进行；或说明用途或作用。(单个一词作定语，须放在所修饰词的前面；短语作定语须放在所修饰词的后面)
e.g. The lady talking (who is talking) with him is a doctor.
Will the swimming pool be open?
The man walking by the lake is a scientist.
5. 作补语。作宾语有两个特征：一是宾语与 v.– ing 有主谓关系,且宾语是v+ing动作的执行者；二是v.+-ing形式所表示的动作正在进行。
e.g. We heard the boy crying there.
You can see them performing every night.
When I entered the room, I found him listening to the radio.
跟 v+ing 作补语的词常是感官动词和使役动词，如notice, see, hear, watch, get, feel, have, find, keep, observe, look at, listen to, smell etc.
6. 作状语。常作表示原因、时间、结果、条件、让步、伴随或方式状语。其逻辑主语是句子的主语且句子的主语是动作的发出者。
e.g. Being blind, how could they see an elephant?
He sat at the desk reading a book.
Seeing from the hill, we find the city beautiful.
II. NOTES
V+ing 形式一般式和完成式，有主动语态和被动语态，共四种形式，以tell为例
asking being asked
having asked having been asked
一般式表示与谓语动作同时（或在其后）发生；进行式表示发生在谓语动作之前。
e.g. He is proud of being learned. (He is proud that he is learned.)
I am sure of John’s coming in time. (I am sure that John will come in time.)
I am sure of his having been elected. ( I am that he has been elected.)
V+ing 的否定形式是在V+ing前加 not.
e.g. What is troubling them is their not having enough knowledge about computer.
