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.)

e.g. What is troubling them is their not having enough knowledge about computer.

有些动词接不定式和V+ing，意思基本一样。如begin, start, continue, plan, can’t bear, like, love, hate, prefer, intend…
e.g. Let’s continue to study/ studying law. (让我们继续学习法律。)
但，有些表示系恶的动词，如like, love, hate, prefer, intend …，接v+ing 表示一般的喜恶，接不定式表示特别的情况。

　　　I’d like to go to the theatre if you with me.（特殊）
下列动词或短语，need, want, require, bear, demand, be worth… 接v+ing 的主动形式，表示被动意义， 与接不定式的被动形式意义大致相同。
e.g. This problem needs looking into. (This problem needs to be looked into. )
　　　This book is worth reading twice. (This book is worth to be read twice.)
在下列动词或短语后，如，stop, remember, forget, regret, try, mean, go on, go afraid…
可以接v+ing 也可以接不定式，但意义不同。

3. on + v+ing 表示“一。。。就。。。”

5. keep, stop, restrain, hold + Sb. / Sth.+ from + v+ing… 表示“阻止某人/某物做谋事”
e.g. Nothing can stop me from going to school.
V+ing 在句中作宾语 、表语或主语时，如果它的逻辑主语和句子的主语不一样时，要有自己的逻辑主语。用“物主代词、名词所有格、名词通格、代词宾格”在 v+ing 前面表示逻辑主语。作宾语和表语时，常用物主代词、所有格、通格、宾格；作主语时，常用所有格和物主代词。
e.g. Their coming to help us was a great encouragement to us.
　　　Does he object to Xiao Ming’s joining the amateur drama group?
　　　I don’t like my sister’s going to such a place. (=I don’t 　　　like my sister going to such a place.)
