动名词
动词-ing形式用作名词

1. 动名词的时态和语态

示的动作同时发生, 或在谓语动词表示的动作之后。

(2) 动名词的完成式所表示的动作或状态在谓语动作
之前完成或结束。

2. 动名词的句法功能
动名词在句中可以作主语、表语、宾语、定语等。
1.作主语
Swimming is good for your health.
Talking about problems often helps.
Collecting stamps is a good hobby.
Seeing is believing.
习惯表达法
It is no use (good) + doing 做某事没有用
There is no + doing (= It is impossible to do sth.)
It’s no use crying over the spilt milk now.
There is no knowing what may happen.
为平衡整个句子,避免头重脚轻,常用it做形式主语,而将真正的主语-----动名词放后面。
2.作宾语
He often practices playing the violin at the weekend.
I love swimming in the sea during the summer.
He tried to avoid answering my questions.
Do you mind my smoking here?
Would you mind helping me with my homework?
常见接动名词作宾语的动词有admit, enjoy, imagine, practise, delay, miss, consider, finish , mind, keep, suggest,avoid等
一些短语后要接动名词作宾语 如:cannot help, look forward to, feel like, cannot stand,put off, keep on等
有些动词(如begin, start, continue, like, love, prefer, hate)后既可以接V-ing作宾语,也可以接不定式to do作宾语,意义差别不大
有些动词(如forget, regret, remember, mean, try, go on)后既可以接V-ing作宾语,也可以接不定式作宾语,意义不一样
注意

就我而言,我想和诚实、心地善良的人交朋友;我想和那些能够与我分享快乐、分担忧伤的人交朋友。拥有这样一位朋友,我感觉到生活的意义和完整。没有理由不努力使这种友谊永世长存。为了能够达到这一点,你需要与朋友相互理解,相互信任。珍惜你的朋友,生活将变得五彩斑澜。
范文:
Friends play an important role in our lives. I think true friends are like the air without which we can’t live. So it’s hard to imagine what life will be like without friends.
For me, I want to make friends with those who are honest, kind and who can share joy and sorrow with me. Having such a friend, I feel life is meaningful and complete. There is no reason not to make efforts to keep the friendship lasting forever. To achieve this, you need to understand and believe each other. Cherish your friends and life will be colorful.
