一、非谓语动词形式 a. 动词不定式 b. v-ing c. 过去分词
二、概述：1.谓语动词：在句子中担任谓语的动词。2.非谓语动词：是动词的特殊形式,在句中可以作除谓语外的所有成分。
三、非谓语动词使用条件
一个句子当中，已经存在一个主句（谓语动词）,又没有连词的情况下, 还有别的动词出现时。She gt ff the bus, leaving her handbag n her seat.She gt ff the bus, but left her handbag n her seat.
一．动词不定式的时态和被动形式动词不定式是非谓语动词的一种，由不定式符号(t)加动词原形构成。不定式的形式有五种：1.一般式t d I like t read English.2.进行式t be ding He seemed t be reading smething at that time.3.完成式t have dne He seemed t have cleaned the rm.4.被动式t be dne The wrk is t be dne sn.5.完成被动式t have been dneThe by is said t have been sent t hspital yesterday.
疑问词+动词不定式What, wh, which, where, when, hw, why等疑问词构成不定式短语，这种短语在句子中可作主语、宾语和表语等成分。
作表语动词不定式往往放在连系动词be的后面作表语。（1）常说明主语的内容、性质、特征。 ✮ My wish is t becme a teacher. ✮ Yur jb tday is t clean the playgrund. ✮ T be kind t the enemy is t be cruel t yurself. ✮ My suggestin is t put ff the meeting.
（2）动词不定式作表语，表示将来。✮They are t marry next week.✮Yu are t deliver these flwers befre 10.
动词的ing形式（v-ing/ding）一. 动词的ing的基本构成
例句：N ne likes being laughed at.I dn’t remember having ever been given a chance t d it.
二.v-ing的功用✮v-ing 相当于adj. adv. n.的功能。✮在句中可作：主语，宾语，定语，状语，表语，宾语补足语。
作表语, 表抽象的，一般的行为，表主语的特征、性质和内容。✮ It sunds interesting.✮ The bk seems bring.✮ My jb is lking after children.
过去分词1.过去分词相当于adj.和 adv.的功能，2.它可以作定语，状语，宾语补足语和表语。3.过去分词的用法，一是表完成，二是表被动。4.规则动词的过去分词以-ed结尾构成，不规则动词的过去分词变化见不规则动词表。
作表语The cup is brken. (表被动，完成)He is retired. (完成)注意 过去分词作表语与被动语态的区别。The cup was brken by my little sister yesterday. (被动语态，表示动作)The library is nw clsed. (过去分词作表语)
注意 过去分词作表语与v-ing形式作表语的区别：interest, bre, wrry, surprise, frighten等通常用其过去分词来修饰人，用v-ing形式来修饰物。The bk is interesting and I’m interested in it.→We are excited at the news.→The news he tld us is exciting.
动名词短语作表语与动词不定式（短语）作表语的区别：动名词短语作表语表示一般性的动作；动词不定式（短语）作表语表示一次具体的动作或将要发生的事。His hbby is painting. 他的爱好是画画。（一般性的动作）Tday what he wants t d is (t) paint. 今天他想要做的事情是画画。（具体的动作）His wish is t becme an artist. 他的愿望是成为一名艺术家。（将要发生的事）
