V-ing做定语和表语
非谓语:1. to do (表目的和将来)
2. doing (v-ing)(表主动和正在进行):现在分词、动名词
3. done(v-ed)(表被动和完成)
动词-ing形式由“动词原形 + ing”构成。动词-ing形式可在句中作主语,宾语,表语,定语,宾语补足语和状语,但是不能单独作谓语。
一.V-ing 做表语
1. 现在分词做表语
(1) The argument is very convincing.
(2) . They were very shocked at the news.
分词作表语,多表示主语具有的特征和状态。
现在分词(doing)作表语,多表示主语具有的特征,常译为令人……;
过去分词作表语(done),多表示主语具有的状态,常译为感到……。
2. 动名词做表语
(1). Seeing is believing.
(2). Her job is cleaning the windows of that high building.
动名词作表语与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。
V-ing 做现在分词和动名词的区别:现在分词说明主语的特征;动名词说明主语的内容。因此,动名词作表语可以和主语互换位置,而现在分词不可以作主语。

二.V-ing 做定语
1.V-ing作前置定语——相当于形容词
动词ing形式作定语的意义
1 动名词作定语表示名词的性质、特征或用途。
2 现在分词作定语表示名词的状态:进行、主动。
2.V-ing做后置定语
现在分词(doing)短语作定语时,通常做后置定语,其作用相当于定语从句。
总结:
1. -ing形式作定语:
1 单个动词的-ing形式作定语, 位于被修饰名词的前面,相当于形容词,表示被修饰者的作用和功能,被修饰者的性质和用途,被修饰者正在进行的动作。
2 -ing形式短语作定语,相当于一个定语从句。
2. -ing形式作表语:可分为现在分词和动名词
现在分词可看做形容词,翻译为“使人……的”
