4. 作状语: I’ll never forget the day when I first came to Beijing.

This is the house where I was born.

3. 作定语:　 关系代词whose在定语从句中作定语用。例如：

What’s the name of the young man whose sister is a doctor?

The girl whose father is a teacher studies very hard.

2. 作宾语： She is the person that I met at the school gate yesterday.

The book that my grandmother gave me is called “The Great Escape”.

　　 关系代词和关系副词用来引导定于从句，在先行词和定语从句之间起纽带作用，使二者联系起来。关系代词和关系副词又在定语从句中充当一个成分。关系待客做主语，宾语，定语，关系副词可作状语。

1. 作主语：关系代词在定语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。例如： I don’t like people who talk much but do little.

The cars which are produced in Hubei Province sell very well.

　　 在复合句中，修饰某一名词或代词的从句叫做定语从句。被定从句修饰的词叫做先行词。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词和关系副词。例如：

This is the present that he gave me for my birthday.

Do you know everybody who came to the party?

I still remember the night when I first came to the village?

This is the place where Chairman Mao once lived.
