关键句型—动名词

1)动名词是动词的一种非谓语形式; 2)v.+ing形式; 3) 它在句中充当名词的作用,可单独或引起短语 作主语,表语,动词宾语,或介词的宾语以及定 语。)

Subject
1) V-ing 形式作主语 往往表示抽象、笼 统的动作或泛指某动作或行为。如: a.) Getting up early is a good habit. b.) Fishing is Tom’s favorite hobby. c.) Crying over spilt milk is no use. d.)Arguing with him is a waste of time.

注:动名词作主语与不定式作主语的区别:
动名词作主语通常表示抽象的或泛指的动作,一般不与特定的 往往与特定的动作执行者联系在一起,如: It’s no use crying over spilt milk. (抽象) He realized that to go on like this was no use. (具体)

动作执行者联系在一起;不定式作主语通常表示具体的动作或行为,

在实际运用中,一般可以互换,差异不大。但

在下列几种情况中不能互换:
a. 当表语是动名词时,主语也要用动名词;当表语是不定式时,
主语也要用不定式,如: Seeing is believing.

To see is to believe.

b. 动名词和不定式作主语,一般都可以使用形式主语it,而将动名 词或不定式放在句尾。但是在下列句型中,一般宜用动名词,不宜 用不定式来代替: It’s no use doing … It’s no good doing… It’s a waste of time doing … 例如: It’s no use going there today; he won’t be at home. It’s a waste of time arguing about it.

而在It’s important … / It’s necessary … / It’s advisable … / It’s essential … / It’s fitting … 这类句型中,只能用不定式,如: It’s important to learn foreign languages. It’s quite necessary to read it many times.

Predictive
2) V-ing形式作表语 (放在系动词之后,泛指 某种动作或行为,常用来说明主语的身份、内 容或特点。)如:

a.) My job is testing all kinds of software. b.) The purpose of my letter is advising you to do more sports. c.) His greatest happiness is serving the people. d.) Seeing is believing.

注①:动名词作表语与不定式作表语的区别:
动名词作表语时表示比较抽象的一般行为、习惯;不

定式作表语时表示具体的某一次动作,特别是将来的动作,
试比较:

My favourite sport is swimming.
The first thing for us to do is to improve our

pronunciation.

注②:动名词作表语与现在分词作表语的区别:
动名词作表语时相当于名词,说明主语的含义及内容,它与主语 是同等关系,主语与表语互换位置不影响句子的基本含义,但不可 用副词来修饰。 现在分词作表语时相当于形容词,说明主语的特征、性质、状态 等,主语与表语不可互换位置,但可用very, quite等副词来修饰,

如:
My job is looking after the children. Our duty is serving the people heart and soul. The situation is encouraging. This cake is very inviting.

The volleyball match we watched was very exciting.

Object
2) V-ing形式作宾语 a.) She sat there without speaking. b.) David is interested in driving. c.) Do you mind turning on the TV? d.)Betty enjoys listening to pop music.

能用动名词作宾语的动词有两类: 一类是只能用动名词作宾语的动词,其中有:avoid, admit, consider, delay, advise, dislike, enjoy, escape, excuse, mind等,(+Ving的动词)如: Mary is considering changing her job. I enjoy working with you. Would you mind ringing me up tomorrow? 另一类是既可以用动名词,又可以用不定式作宾语的 动词,其中有:continue, forget, hate, intend, like, love, plan, prefer, propose, regret, remember, start, try, want, need, can’t afford等。


B. 在need, want, deserve等后,可用动名词的主动式表示被动含 义,或用不定式的被动式,意义上无差别。但用动名词较为普遍, (这时主语一般是物),如: The door needs oiling / to be oiled. C. 有的动词尽管可以用两种结构,但意义明显不同,须认真加以 区别: I forgot to close the door before I left the room. I forgot having closed the door. He tried to write better. (尽量努力地写) He tried writing with a brush. (用毛笔试着写) I couldn’t help finishing it. (不能不结束某事) I couldn’t help to finish it. (不能帮助结束某事) They left off fishing. (停止钓鱼) They left off to fish. (离开某处出发去钓鱼) I regret to say that there is no wine in the bottle. (对现在要发生的 事表示遗憾、抱歉) I regret not taking your advice. (后悔)
