ving作定语

动词的-ing形式做定语在句中通常有两个位置，

（1）如果是单个的动词的-ing形式做定语，常放在被修饰词前做前置定语;

He is an attacking player.

A little child learning to walk often falls.

Do you know the number of people coming to the party?

（2）如果是动词的-ing形式的短语做定语，常放在被修饰词后做后置定语。

1.A young man writing novels came to speak to us yesterday.

→A young man who writes novels came to speak to us yesterday.

2.The girl sitting next to me was my cousin.

→The girl who was sitting next to me was my cousin.

-ing形式做定语通常从以下三方面考查，即：

　　1)说明被修饰词的性质，特征或用途。如：

1.They set up an operating table in a small temple.

2.He may be in the reading room，for all I know.

　　2)与被修饰词为主动关系且表示正在进行的动作。如：

1.There were about 200 children studing in the art school.

2.Who is the woman talking to our English teacher?

　　3)有些-ing形式已经转化成形容词，常做定语用来修饰物，表示“令人……”。　　3)有些-ing形式已经转化成形容词，常做定语用来修饰物，表示“令人……”。

　　1.That must have been a terrifying experience.那准时一段可怕的经历。

　　2.The experiment was an amazing success.那项试验是一个惊人的成功。

　　3.There is a page missing from this book.这本书

除了-ing形式能做定语外，如果-ing形式与被修饰词是被动关系，就用它的被动式，即being done.being doing通常表示正在被做，常做后置定语。如：

1.The tall building being built now is our new school.正在被建的高楼是我们的新学校。

　　2.The question being discussed was presented by the headmaster.正在被讨论的问题是被校长提出的。
