一、
1.介词后面加-ing,大多介词-to的后面跟动词原形,但 look forward to 除外,这个短语的后面就要 加ing .
2.有的动词需要特殊记忆,因为这些后面所跟动词的形式就要用ing形式。
例如:find doing sth 、spend doing sth 等等。
3.动词做主语开头时也要加ing,但祈使句除外,祈使句的动词开头用原形。
例如:Playing basketball is my favorite sport .
Come on ! ( come是动词,但因为这个短语句子是祈使句,所以用原形。)
二、
1. -ing分词的构成
-ing分词是由动词原形加词尾-ing构成。-ing分词同样有时态和语态的变化.

2. -ing分词的一般式和完成式:
-ing分词的一般式表示和谓语动词所表示的动作同时进行的动作

3. -ing分词的被动式:
-ing分词的被动式表示它的逻辑主语是-ing分词动作的承受者。
The question being discussed is very important. 正在被讨论的问题很重要。
注意:在need, want, require, be worth等动词(短语)后,作宾语的-ing分词常用主动形式来表示被动含义。如:

This book is well worth reading. 这本书很值得一看。
4. -ing分词的语法作用
-ing分词一方面具有动词的性质,另一方面也相当于一个名词或形容词、副词,在句中可以作主语、表语、宾语、定语、状语和补语等。

5. -ing分词的复合结构:

1. –ing分词作主语和表语时与不定式的区别:

It’s not good for you to smoke so much. (指你吸烟)吸这么多烟对你的身体不好。
My job is teaching. 我的工作是教书。
My job is to teach you English this term. 我这一学期的工作是教你们英语。
2.能接-ing分词作宾语的常见动词:
mind(介意), enjoy(欣赏,), finish(完成), keep(保持), miss(错过), 等。
3. 有些动词既能接不定式,又能接-ing分词,含义有所不同。如:
①forget, remember, regret等词后面接不定式表示不定式动作后于谓语动作,而后接-ing分词作宾语表示分词动作先于谓语动作。如:
Do you remember seeing me before? 你记得以前见过我吗?
Remember to lock the door when you leave. 离开时要记得锁门。
②动词mean, stop, try, go on等动词后面接分词和接不定式作宾语,意思也有所不同。如:
I try not to think about that. 我尽量不去想那件事。
Would you please try doing that again? 请你再试一次好吗?
He stopped talking when the bell rang. 铃响的时候,他停止了讲话。
While working, he stopped to talk with Tom at times. 工作的时候,他不时地停下来和汤姆谈话。
注意:有时人们把stop后的动词不定式理解为目的状语。
③动词allow, advise等可直接跟-ing分词作宾语,不可以接动词不定式作宾语,但可接不定式作宾语补语。如:
Please allow me to say a few words. 请允许我说几句话。
We don’t allow smoking here. 我们这儿不允许吸烟。
④动词need, require, want作“需要”解时,后面接-ing分词或不定式的被动式。如:
The room wants cleaning/to be cleaned. 这个房间需要打扫。
These little children require looking after carefully/to be looked after carefully. 这些小孩需要细心地照料。
⑤动词like, hate, prefer等后面,如表示一般性动作,多用-ing分词;如指特定的具体的某次动作,多用不定式。
I like swimming, but I don’t like to swim with you. 我喜欢游泳,但我不喜欢和你一起游泳。
I prefer walking to school every day. 我情愿每天步行去学校。
I prefer to stay at home today. 今天我情愿呆在家里。
