动名词(Ving) => 当主词，受词，补语
一、动名词当主词
祈使句：Do it right now (立刻去做)
直述句：Doing / To do it right now is important (现在做这件事很重要)
例：1. Sleeping / To sleep eight hours a day is good for health => It is good for health to sleep eight hours a day (一天睡八小时有益健康)

注意：It's no use crying over spilt milk (牛奶撒了,哭也没有用 => 覆水难收)
二、动名词当受词：放一般动词或介系词后
1.当一般动词的受词
a.下列动词后接Ving或者to V当受词，意义不变。例：like，love，hate，learn，start，begin等
例：1. I like (watching / to watch) basketball games on TV (我喜欢看电视上的篮球比赛)
2. They began (dancing / to dance) faster and faster (他们开始跳得越来越快)
b. 下列动词后接Ving或者to V当受词，意义改变。例：stop，remember，forget，try等,接to V代表动作还未做，接Ving代表动作已做
