Teaching Procedures (1)

引导学生注意到动词的-ing形式

(2)

Discovering useful structures Walking is good exercise. Reading makes a full man. Would you mind turning down your radio a little, please?

What can yon do besides typing?

总结：动词的-ing形式在句中作

和

，起一个

的作用，我们通常称之为“动名词”。

一、动词-ing形式作主语

Walking is a good form of exercise for both young and old.

Watching news on TV has become a routine for me.

总结：表示

动作或状态, 谓语动词通常用

。

2.

is no use making an excuse for this. 总结：-ing形式作主语时常后置, 此时须用

作形式主语, 用形容词或名词作表语。

常见的名词或名词短语有: no use, no good, fun, hard work, a hard / difficult job, a waste of time 等; 形容词有: dangerous, worthwhile, useless等。

3.动名词与不定式做主语时的比较：

动名词表示的动作通常是一个泛指的动作，不定式则通常表示具体的动作。如：

Being a guest in an American home will be a good experience for me. It’s an honor for me to be invited to the party.

归纳：常用-ing形式作主语的句型有：

It +be +a waste of time doing

It is/was no good/use doing

It is/was hardly/scarcely worth doing

It is/was worth/worthwhile doing

There is no doing... There is no sense in doing

There is/was no use doing

There is/was nothing worse than doing

There is/was no point doing

注意：There is no need to do sth

在此句式中to do不可换为doing. 二、动名词用作宾语

动名词作宾语有两种情况。

1. 只能后接动名词作宾语的动词，常见的有

avoid, consider, enjoy, keep, finish, suggest, dislike, delay, escape, cannot help, imagine, mind, miss, practise, cannot stand, excuse, fancy, give up, put off, risk, insist on, look forward, feel like等。

We must try to avoid repeating the same mistake．

Do you feel like having a walk with me after supper?

2. 既可接动名词又可接不定式作宾语的动词,

常见的有: begin, start, continue, like, love, prefer, by, mean, forget，remember, hate等。

A. 在

like, love, hate, prefer等动词之后。动名词表示泛指的动作，不定式表示具体的一次性动作。

B. 在

begin/start, continue之后, 用动名词和不定式, 意义无甚区别, 尤其是当主语是人的时候。

C. 在动词forget, remember, regret之后, 用动名词与不定式意义不同。动名词表示动作先于谓语发生，不定式表示后于谓语动作，如：

I remember posting the letter．

I’ll remember to post the letter．

D. 在try, mean, go on, stop等之后，意义各不相同。

We must try to get everything done in time．

Let’s try doing the working in some other way．

I didn’t mean to make you angry．

Your plan would mean spending hours．

3. 作介词宾语

We’ve got to think of ways of changing people’s habits.

Instead of smiling, each of them made a face．

下列短语中的to都是介词, 所以后面跟名词或-ing形式: devote to, object to, pay attention to, get down to, lead to, look forward to, stick to,be used to等。
