例如：The book which is on the table is mine.（在桌子上的那本书是我的。
）3. 当定语从句中的先行词是人或者物时，我们可以使用that作为关系代词。
例如：The house that I live in is very old.（我住的那个房子非常旧。
）4. 当定语从句中的先行词是人时，如果在从句中作为宾语，我们可以使用whom或者that作为关系代词。
例如：The girl whom I met yesterday is a doctor.（我昨天遇到的那个女孩是个医生。
）5. 当定语从句中的先行词是人或者物时，如果在从句中作为所属关系，我们可以使用whose作为关系代词。
例如：The man whose car was stolen reported it to the police.（车被偷的那个人向警察报案了。
）三、关系代词与介词的使用当定语从句中有介词时，我们需要注意关系代词与介词的搭配。
定语从句关系代词讲解
The Attributive Clause-定语从句一、概念:在复合句中修饰名词或代词的句子. Mary is a beautiful girl.形容词作定语Mary is a girl who is beautiful.句子作定语,修饰girl, 叫做定语从句 Mary is a girl._______________________________Mary is二、关系词判断步骤(1)首先，要看先行词。
如果先行词是指人,关系代词可用 who,that,whom,whose ，如果先行词指物,关系代词可用which 或that ；(3)最后，定语从句谓语动词和先行词一致.注:定语从句的时态不受主句的限制。
The woman who/that spoke at the meeting yesterday is my mother.（定语从句） (先行词)（关系代词）(主句)The woman is my mother. (叙述客观事实 用一般现在时)(从句)The woman (who/that) spoke at the meeting yesterday.(句中yesterday表示过去时间)三、定语从句的用法:(1)当先行词是物时, 用which 或that引导.Eg:These are the trees which/that were planted last year.(2)当先行词是人时, 用who, whom,whose, that引导.Eg:The girl who/that has blue eyes is my sister.四、who, whom, whose, that用法区别.先行词为“人”，且在定语从句中作主语或宾语.做宾语时可省略is a worker.(分解is speaking at the meeting.(做主语)The boy who is tall is Tom.Eg:The boy is Tom.（tall、strong、clever）The boy who is strong is TomThe boy who is clever is Tom（指出先行词做什么成分）(1)The boy is Tom. The boy is smiling._____________________________(2)The boy is Tom. The boy has a round face._____________________________(3)The boy is Tom. He sits in front of me.__________________________作定语从句的宾语,在口语和非正式文体中常用who代替，可以省略.The woman whom/who they wanted to visit is a teacher.The woman is a teacher.分解They wanted to visit the woman.（who做visit的宾语）Eg: The man is kind. Everyone likes him.The man (whom) everyone likes is kind.(宾语)(1)The woman got the job. We saw her on the street._______________________________________(2)The teacher will give us a talk. We met the teacher yesterday.________________________________________whose作定语从句的定语.whose 是代词的所有格形式, 它既可以代人也可以代物。
