动名词是非谓语动词的一种，它由动词原形加-ing构成，形式上与现在分词相同。动名词除具有动词的性质外，还具有名词的性质。动名词在句中可用作主语、表语、宾语、定语、宾语补足语等，但不能用作谓语（故称动名词为非谓语动词）。如：
Her job is looking after the baby. 她的工作是照顾婴儿。
She loves swimming. 她喜欢游泳。
Thank you for helping us. 谢谢你帮助我们。
She’s gone out to do some shopping. 她出去买东西了。
一、动名词的句法功能
1．用作主语
Seeing is believing. 眼见为实。
Finding work is difficult these days. 现在工作可不容易。
注意：动名词作主语经常采用it作形式主语的句型。
It’s no use crying. 哭没有什么用处。
2．用作表语
Her favorite sport is skating. 她最喜爱的运动是滑冰。
His job is teaching English. 他的工作是教英语。
注意：不定式和动名词均可用作主语和表语，区别是：动名词多指笼统的、抽象的概念，而不定式则多指具体的、一次性的动作。
3．用作宾语
She likes singing and dancing. 她喜欢唱歌跳舞。
He enjoys playing basketball. 他喜爱打篮球。
介词后出现动词时，通常要用动名词形式，不能用动词原形，通常也不用不定式。
Thank you for helping us. 谢谢你帮助我们。
He left without saying good-bye. 他没有告别就离开了。
4．用作定语
This is our reading room. 这时我们的阅览室。
He bought a new washing machine. 他买了一台新洗衣机。
Betty won the first prize in the singing competition. 贝蒂获得了歌咏比赛的一等奖。
