非谓语动词（不定式、动名词、分词）不是真正意义上的谓语动词，在句中都不能单独作谓语。但都具有动词的某些特点，可以有自己的宾语或状语，构成非谓语动词短语。不定式表目的，表将来；动名词表主动，表进行；过去分词表被动，表完成。
一．作主语( 动名词、不定式、过去分词前面加being, 动名词做主语谓语动词用单数)
1）不定式、动名词都可做主语，但是动名词做主语多指抽象的概念性的动作，可以是多次的经常的行为；不定式多表示具体的动作，尤其是某一次的动作。如：
Playing with fire is dangerous. 玩火危险。（泛指玩火）
To play with fire will be dangerous. 玩火会发生危险。
2）用动名词做主语的句型:
It’s no u/no good/pleasure doing sth 做.......没有用处/好处/乐趣
It’s a waste of time doing sth 做大器晚成的人.... 浪费时间
浆面条的做法
It is worth doing sth 值得做某事
It is no u crying over spilt milk. 覆水难收
It is worth making an appointment before you go. 去之前预约一下是值得的。
3）不定式做主语的句型.
It is + adj +for sb to do sth.
比较：表示人的品质时只能用of sb 如considerate/kind/nice/foolish/stupid/rude/cruel /wi/clever/brave/lfish/crazy/good/careful/careless/impolite/right/wrong等单词出现时。
It is silly of you to say so.
It is important for us to learn English well.
It is a must/ a necessity for us to have a good command of the English language.
4) “Wh- + to 不定式”可做主语。如：
When to leave hasn’t been decided yet.什么时候动身还没定呢。
Whether to drive or take the train is still a problem.是自驾车还是乘火车仍是一个问题。
5） 一般情况下，不定式和动名词作主语，谓语动词一般用单数形式。如：
Seeing is believing.= To e is to believe 眼见为实。
. Planting flowers needs constant watering.
但and连接的多个动名词作主语，谓语动词大多用复数（如果前后动名词的语义一致，谓语一般用单数）。如：Lying and stealing are immoral. 说谎与盗窃是不道德的。

6) 动名词前面可以加上形容词性物主代词构成动名词的复合结构。如：
----- What made him angry?
------ Mary’s /My/His/Her /Their/ The boy’s/ The president’s being late（made him angry.
7）过去分词不能单独做主语，前面必须加上being，构成动名词，做主语。如：
Being expod to the sun 饥荒游戏攻略is harmful to the skin.
Being examined twice a year , whether it is a car, a bus or a truck, is 四个字的祝福语>八七福利电影the rule that every driver must obey in this city.
