在复合句中修饰名词或代词的从句为定语从句, 关系代词和关系副词在定语从句中担任句子成份。

1.在who引导的定语从句中用作主语 , 如 : This is the boy who often helps me.

2.由whom引导的定语从句中作为宾语,如:The man whom you are waiting for has gone home. 

3.whose引导的定语从句中作为定语 , 如 : Do you know the girl whose skirt is white? 

4.which用作主语或谓语动词的宾语或介词的宾语,如: The room in which there is a machine is a work shop. The river which is in front of my house is very clean. This is the pen which you want. 注意 : 

(1)whom作介词宾语时 , 介词可放在 whom之前;但在含有介词的动词固定词组中,介词不能移动位置。如: He is the very person whom we must take good care of. 

(2)关系代词在句中作为主语时,从句的谓语动词的人称和数必须和先行词保持一致。 

由that引导的定语从句里面,that可以指人还可以指物,但不能把它放在介词后面作介词宾语,注意在下面这些情况下必须用 “that”引导定语从句。  

(1)先行词是不定代词few, little, much, nothing,等 , 如 :Say all that you know

(2)序数词或形容词修饰先行词:如 The first letter that I got from him will be kept.  

(3)先行词被all, any, every, each, few, little, no, some等修饰 , 如 I've eaten up all the food that you gave me

(4)先行词被the only, the very, the same, 修饰时如 He is the only person that I want to talk with.

(5)先行词不但有人还有物时,如:  They talked about persons and things that they met. 

(6)当句中已存在who时 , 为避免重复 , 如 : Who is the man that is giving us the class?

注意:先行词是表示地点的时候,如果从句的谓语动词是及物的,就用 that(which),如果从句的谓语动词是不及物的,就用“where”引导。
