　　一、概念

　　在句子中起定语作用、修饰句中的名词或代词的.从句称为定语从句，被修饰的名词或代词成为先行词。定语从句由关系代词（which，that，who，whom，whose）或关系副词（when，where，why）引导。

　　二、例句

　　1. The flowers which I grew in the garden last month will bloom soon.

　　2. The man who telephoned me just now is a writer. This is the place where my mother was born.

　　三、关系代词的选择

　　1. 充当主语的关系代词关系代词在限定性定语从句中作主语，who 用于人，which用于物，that既可以指人可以指物。

　　2. 充当宾语的关系代词关系代词在限制性定语从句中作谓语动词宾语，who ,whom 用于指人，which用于指物。that 既可以指人，也可以指物。在非正式文体中可省略。The suit(which/that) the tailor suited for me doesn’t fit me.

　　3. 作介词宾语的关系代词在限制性和非限制性定语从句中，关系代词作介词宾语，whom 用于指人，which用于指物，不能用that. The man with whom you shook hands just now is head of our department.

　　五、关系副词的选择
