语法复习十三：非谓语动词（二）——动词-ing形式 （二）-ing形式：动词的-ing形式也是一种非谓语动词。-ing形式仍保留有动词的特征，可以带有其所需要的宾语或状语而构成-ing短语。 1、-ing的形式：-ing有一般式和完成式。及物动词的-ing还有主动语态和被动语态，而不及物动词的-ing则没有被动语态。现在以及物动词make 和不及物动词go为例，将其-ing各种形式列表如下： 动词 语态 形式 及物动词make 不及物动词go 主动语态 被动语态 主动语态 一般式 making being made going 完成式 having made having been made having gone 2、-ing形式的基本用法。 （1）作主语：Seeing is believing.百闻不如一见。Talking is easier than doing. –ing作主语时，如果其结构较长，可用it作形式主语，而将作主语的-ing后置。如：It isn’t much good writing to them again. It’s no use waiting here. （2）作表语：Her job is washing and cooking. My hobby is collecting stamps. （3）作宾语：①作及物动词的宾语。She likes drawing very much.；②作某些短语动词的宾语。 Mary is thinking of going back to New York.；③ do+限定词（my, some, any, the等）+ -ing，表示“做…事”之意，如：We often do our cleaning on Saturday afternoon. Will you do any shopping on Saturday this afternoon? ④作介词的宾语：Her sister is good at learning physics.；⑤作形容词worth, busy等的宾语：This book is well worth reading. –ing作宾语带有宾语补足语时，要用it作为形式宾语，而将作宾语的-ing后置，如：We found it no good talking like that. Do you think it necessary trying again? |
