(主语)

(表语)
Seeing is believing.
Helping her is my duty.
动词-ing作主语和不定式做主语一样,也可用it作形式主语。如:
It’s rather tiring walking around in a city. 常用句型有
It’s no use/good/a waste of time+doing
一、动词-ing作主语的用法
不定式作主语往往表示具体的特别是将来的动作;v-ing 做主语表示抽象或一般动作。如:
It’s a waste of time playing computer games.
It is easy to repeat this word.
(指抽象动作)
(指具体动作)
注意:
1、 动名词作主语表单数概念,谓语动词用单数形式。
Walking after supper is good for your health.
2、 动名词的复合结构作主语
动名词前的物主代词或名词所有格和动名词一起做主语
Your coming made us happy.
Your father’s cooking is very good.
考 例
1. — What do you think made Mary so upset?
— ______________ (lose) her new bicycle.
解析: losing her new bicycle是句子的主语,谓语made her so upset被省略;losing…在此表示具体的动作。
