The Gerund

动名词是动词的另一种非限定形式。 基本形式:v-ing form

特点:具有动词和名词的性质;它在句子中起名词的作用 用法:可用作主语,表语,宾语,介词宾语或定语 1. 作主语

Smoking is a bad habit. It’s nice talking to you.

注意:在it is no use/good, not any use/ good, useless等后一般用动名词。

2.作表语

My favorite sport is swimming.

注意:动名词和不定式都可以作主语或表语。一般来说,在表示比较抽象的一般的行为时多用动名词;在表示具体某次动作,特别是将来的动作时,多用不定式: Playing with fire is dangerous.(泛指玩火) To play with fire will be dangerous.(指一具体动作)

3.作宾语

I enjoy working with you.

注意:①在suggest, finish, avoid, stop, can’t help,can’t stand,mind, admit, enjoy, appreciate, excuse,forgive,imagine, keep, resist, risk, include, mention, advise, deny, miss, escape, require, delay, practice, consider, feel like, give up,insist on, object to, put off, set about, be worth, look for, get/be used to等动词后用动名词(不能用不定式)

②在remember, forget, consider, regret, stop, mean, trybegin. Start, intend, continue等动词后,既可以用动名词,也可以用不定式,意义有差别。 remember to do eg: Remerber to tell him about it, remember doing eg: I remember telling you about it. forget to do eg: He forgot to bring his umbrella. forget doing eg: He forgot taking the key.

regret to do遗憾要做 eg: I regret to tell you that you failed the exam. regret doing做了某事而后悔 eg:I regret selling the house. stop to do eg: He stoped to read the book. stop doing eg:Stop talking.

mean to do打算 eg: I mean to visit the place. mean doing意味着

try to do表目的eg: We must try to get everything done in time. try doing 表手段、方法eg:Why not try knocking at the back door? Start to do 表示情况发生变化 eg: suddenly it started to rain.

Starting doing 表示有意识地开始 eg: Then the little girl started singing.

③有时两种结构只有细微的差别,如在like, love, prefer,hate等词后,动名词多表示一般情况,不定式多表示即将发生地事;有时两者可以互换,意思上没有差别。

④need, require, want 当“需要”讲时,其后跟动名词作宾语或不定式的被动式,即主动形式表被动含义。

The room needs/ requires/wants cleaning. to be cleaned.

4.动名词作介词宾语

He insisted on doing it in that way. I got used to working in the evening. What can you learn by watching such films.

5. 作定语 (说明宾语的功能) He has a reading room. Swimming pool

6. 动名词的逻辑主语 (动名词的复合结构)

动名词的逻辑主语多用一个物主代词或名词所有格表示,可用在:1) 主语前:

My coming there will be helpful.

Their coming to help was a great encourage to us. 2) 表语前:

The trouble is their not having enough room. Our worry is your relying too much on yourself. 3) 宾语前:

Do you mind my reading your paper?

3

She forgot my telling her about it. 4)介词的宾语前:

They insisted on my staying there for supper. 他们一定要留我在那儿吃晚饭。

注意:我们也可以用一个名词所有格来构成这种结构,如: I enjoyed Tom’s singing.

They are looking forward to Tom’s coming. 动名词复合结构的一般规律:

①Tom’s (His) coming is what we have expected.(有生命,作主语,用名词或代词所有格)

She didn’t mind Jack (him) coming late. (有生命,作宾语,用名词或代词宾语) They insist on Tom’s (his) staying longer. (有生命,作宾语,用名词或代词所有格) ②逻辑主语是无生命名词时,只用名词普通格。 Is there any hope of our team winning the match?

③逻辑主语是指示代词或不定代词this, that, somebody, someone, nobody, anything时, 只用普通格。

She was disturbed by somebody shouting outside.

动名词的时态和语态 一般式 完成式 主动形式 doing having done 被动形式 being done having been done 动名词的一般形式通常表示一般性动作(即不是明确地在过去、现在或将来发生的

4

动作)(a)或是与谓语所表示的动作同时发生的动作(b): a. They are all interested in climbing mountains. b. He took a great delight in helping others.

如果要表示动名词代表的动作在谓语所表示的动作之前发生,我们通常要用动名词的完成形式:

I regret not having taken her advice. he didn’t mention having met me.

当一个动名词逻辑上的主语所表示的是这动作的对象时,这动名词一般要用被动形式:

He didn’t mind being left at home. 把他留在家里他并不在意。

He could not bear being made fun of like that. 人家这样开他的玩笑他受不了。

如果表示的动作在谓语表示的动作之前发生,有时需要用动名词的完成被动形式: I don’t remember having ever been given a chance to try this method. 我不记得谁给过我试验这方法的机会。

(但在多数情况下避免使用这一形式,而用一般被动形式代替,以免句子显得累赘)。
