动名词用法
动名词是一种非谓语动词形式,其结构为“动词原形+ ing”。形式上与现在分词一样,但与现在分词有很大区别。动名词既具有动词特点,又具有名词特点。
作主语
1、动名词是由动词变化而来,所以,动名词的意义也是表示某个动作或事情。
1. Reading English aloud in the morning is a good way to learn English.
2. Cheating on an exam ruins one's character. 考试作弊毁坏人的性格。
3.Being careless is not a good habit.
4.As is known to all,_____________( 吸烟) does harm to people’s health.
5.Mary’s (不可用Mary) being ill made her mother upset.
6.His (不可用Him) ____________(不按时起床) made his mother angry.
subject
二、作表语
1、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。
My job is looking after the children.
= Looking after the children is my job.
Our duty is serving the people.
= Serving the people is our duty.
三、作宾语
1、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:advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, 等。
I enjoy working with you.
After hearing the funny story, all of us
couldn't help laughing ear to ear.
Would you mind ringing me up tomorrow
四、作定语
动名词作定语表用途;现在分词作定语表示动作正在进行。例如:

2.walking stick 手杖 6. opening speech 开幕词
3.listening aid 助听器 7.waiting room 候车室
4. running water 自来水
