高中英语语法 非谓语部分

非谓语动词在句中的一些用法

1. 动词-ing形式和不定式作主语和宾语

★作主语

通常,动词-ing形式着重过程,不定式着重结果。但有时二者有下列不同之处:

1)动词-ing形式的逻辑主语可能泛指人们,而不定式的逻辑主语则常是句子中的名词或代词。

2)动词-ing形式可表示一般或抽象的多次性的动作,而不定式则往往表示具体的或一次性的动作。

★作宾语

1)有些动词后常跟不定式作宾语。这类动词常见的有agree, aim,

arrange, choose, decide, demand, desire, determine, expect,

fail, intend, learn, plan, manage, offer, prepare, pretend,

promise, refuse, threaten, wish等。

2)有些动词后常跟动词-ing形式作宾语。这类动词常见的有admit, dislike, appreciate, avoid, enjoy, bear, escape, stand,

deny, consider, mind, miss, finish, resist, imagine, risk,

practice, suggest等。 2. 非谓语动词作定语

1)不定式作定语

a. 作定语的不定式与它所修饰的名词或代词在逻辑上可能是主谓关系,也可能是动宾关系。如:

The next train to arrive was from New York.

It was a game to remember.

b. 名词前有only, last, next,序数词或形容词的最高级时,其后常用不定式作定语。如:

Rita was the only person to complain.

He was the first man to fly across the Atlantic.

Alex is the best man to do the job.

c. 有些名词的同根动词后常跟不定式,因而这些名词后也常跟不定式作定语。如:

Their offer to assist in the work was not taken seriously.

(比较:They offered to assist in the work.)

2)动词-ing形式作定语可表示正在进行的动作,也可表示经常发生的或短暂的动作以及经常存在的状态。如: The woman sending her children to school is my history

teacher.

A little child learning to walk often falls.

3)过去分词作定语常表示被动或已经发生的动作。如:

We’ve met the doctors sent to work here by the city

hospital.
