关键句型—动名词
1）动名词是动词的一种非谓语形式；
2）v.+ing形式;
3) 它在句中充当名词的作用，可单独或引起短语作主语，表语，动词宾语，或介词的宾语以及定语。）
V-ing 形式作主语 往往表示抽象、笼
统的动作或泛指某动作或行为。如：
a.) Getting up early is a good habit.
b.) Fishing is Tom’s favorite hobby.
c.)Arguing with him is a waste of time.
Subject
2) V-ing形式作表语 (放在系动词之后,泛指某种动作或行为,常用来说明主语的身份、内容或特点。)如：
a.) My job is testing all kinds of software.
b.) The purpose of my letter is advising you to do more sports.
c.) His greatest happiness is serving the people.
d.) Seeing is believing.
Predictive
系动词又称连系动词，不单独作谓语，必须与表语连用构成系表结构。
基本上有三个方面内容：
一个就是be和其变形，如：am，is，are，was，were，been，being；
第二类可以称为感官性系动词，如feel，taste，look，seem，sound；
第三类可以称为变化性系动词，如：become，grow，get，turn。
2) V-ing形式作宾语
a.) She sat there without speaking.
b.) David is interested in driving.
c.) Do you mind turning on the TV
d.)Betty enjoys listening to pop music.
Object
★ 能用动名词作宾语的动词有两类：
一类是只能用动名词作宾语的动词，其中有：avoid, admit, consider, advise, dislike, enjoy, escape, excuse, mind等，（+Ving的动词）如：
Mary is considering changing her job.

另一类是既可以用动名词，又可以用不定式作宾语的动词，其中有：continue, forget, hate, intend, like, love, plan, prefer, propose, regret, remember, start, try, want, need, can’t afford等。
