【合作探究】动词ing形式作表语、定语和宾补 一、动词ing形式作表语
1．表示抽象的一般性的行为，用来说明主语的内容，与主语通常是同一概念，表语和主语常可互换位置。 我的工作是教你们英语。 我最喜欢的运动是游泳。 2．表示主语的某种性质和特征，这时通常可以看作形容词。常见的有astonishing，exciting，amusing，confusing，disappointing，boring，encouraging，inspiring，moving，tiring，interesting，surprising等(这类分词表示“令人……的”的含义)。 她讲的故事很有趣。
我们昨晚看的电影很感人。 二、动词的ing形式作定语
1．表示名词的属性、作用或用途。说明被修饰词的性质、特征或用途，可用“名词+for+动名词”来表达。

如果你确实想吸烟，可以去吸烟室。
2．表示所修饰的名词的动作或状态，与被修饰词为主动关系，且表示正在进行的动作, 相当于一个定语从句。当分词单独作定语时，放在所修饰的名词前；如果是分词短语作定语，则放在该名词后。 大约有50个学生在教室里学习。

动词-ing形式作宾语补足语时，与宾语之间是主谓关系，即宾语是其逻辑上的主语。它主要用于以下两类动词后作宾语补足语。
1．感官动词，如see，hear，feel，smell，watch，find，listen to，look at，notice，observe等。

注意：在see，hear，feel，watch等感官动词后，既可用动词ing形式作宾语补足语，也可用省略to的不定式作宾语补足语。用动词ing形式时，表示动作正在进行，用省略to的不定式时，表示动作从开始到结束的全过程。 I saw a boy ___________(get) on the bus.(表示动作正在进行) I saw a boy ___________(get) on the bus.(表示动作全过程)
2．表示“指使”等意义的动词(使役动词)，如have，set，keep，leave，get等。 那个笑话使他们都笑了。
