一、非谓语动词的概念

动词的基本用法是作谓语。当句中已经有了谓语动词了，要选或要填的动词就只能用非谓语形式了。

二、非谓语形式有三种：
1.动词不定式：todo→表目的或将来
2.动词的ing:doing→表主动和进行
3.动词的过去分词：done→表被动和完成三、非谓语动词的时态和语态动词不定式过去分词动名词/现在分词一般式doingvs.完成式--havingdone时间上的区分v-ing作主语→动名词：相当于名词
Seeingisbelieving.
Readinginbedisbadforyoureyes.
Teachingismyjob.
动名词作主语，谓语动词用第三人称单数形式作主语时，todosth和doing之间的区别
(1)动名词→抽象动作;不定式→具体动作。
Smokingisprohibited(禁止)here.这里禁止抽烟。(抽象)
Itisnotverygoodforyoutosmokesomuch.(具体)
(2)动名词→通常用以表示一件已知的事或经验。
不定式短语→通常用来表示一件未完成的事或目的。
Climbingmountainsisinteresting.爬山很有趣。(经验)
Drivingacarduringtherushhouristiring.在高峰时刻开车令人厌烦。(经验)
Hegetsupveryearlyeverydaytocatchthefirstbus.（目的）
(3)不定式做主语，一般用it当形式主语，把作主语的不定式短语后置。
