今日主题：动名词的用法
1）做主语
It is no use crying over spilt milk .
覆水难收。
It’s a waste of time arguing about it.
辩论这事是浪费时间
There is no joking about such matters.
这种事开不得玩笑。
2)作表语
句子结构：主语+系动词+表语…
S. + be + doing…
His hobby is collecting stamps.
Her job is looking after the old.
注意：这时，主语和表语可以互换位置
3)作定语。
动名词作定语时一般前置，与所修饰的名词间没有逻辑上的主谓关系，表用途。
reading room 阅览室
swimming pool 游泳池
dining car 餐车
singing competition 歌咏比赛
waiting room 候车室
4)作宾语
verb /短语+ doing
avoid, admit, appreciate,
consider, delay, deny,
enjoy, escape, excuse,
finish, imagine, keep, mind, miss,
practice, resist, risk, suggest, understand
be worth
Can’t help can’t stand
feel like
give up put off
有些动词后面，如forget, remember, stop, try, mean, regret、go on等，既可跟动名词也可跟不定式作宾语，但是意义不一样。
He forgot paying for the book.
他忘了曾经付了买书的钱。(他付过钱了)
He forgot to pay for the book.
他忘了去付买书的钱。(他没有付过钱)
Stop talking.(停止说话)
