动词ing又叫做动名词,它和动词不定式的区别主要如下:
动词不定式和动名词都可以用作主语。在意义上相近。但动名词多用来表示泛指或抽象动作,不定式多用来表示特指或具体动作。比较:
Smoking is not good for health. (吸烟有害健康。)
It is not good for you to smoke so much.(你吸这么多烟不好。)
注意:
1)在口语中,用动名词作主语位于句首的较不定式多见。
2)在“It is no use...”,“It is no good...”,“It is fun...”,“It is a waste of time...”等句型中,通常用动名词作真实主语:
It is no use/good/a waste of time talking about that. (多说无益。)
3)在疑问句中,通常用动名词的复合结构,而不用不定式的复合结构作主语:
Does your saying that mean anything to him? (你说的话对他而言有意义吗?)
4)在“There be”句型中,只能用动名词,而不能用不定式作主语:
There is no telling what will happen. (没有预言将发生什么。)
It is impossible to tell what will happen. (预言将发生什么事情是不可能的)
5)当句子中的主语和表语都是非限定动词时,要遵循前后一致的原则,主语和表语在形式上要求统一:
Seeing is believing. (眼见为实。)
*To see is to believe. (眼见为实。)

补充:介词后面只能用动名词,构成介宾短语,如succeed in doing sth(成功做某事)
希望对你有帮助~~
