[语法精释]
who (whom)，which，that，whose引导的定语从句
在复合句中，修饰某一名词、代词或整个主句的从句叫作定语从句。
从句修饰的名词或代词叫作先行词，连接先行词和定语从句的词叫关系词。关系词的主要作用是连接主句和从句，同时指代先行词，并在从句中充当一定的句子成分。关系词分为关系代词和关系副词两种，关系代词有that，which，who，whom，whose等；关系副词有when，where，why。
一、关系代词的基本用法
1．who指人，在从句中作主语或宾语，作宾语时可省略。
The man who is talking with my father is a teacher.
正在和我父亲说话的那个人是个教师。
The girl (who) I met yesterday is his sister.
我昨天见到的那个女孩是他的妹妹。
2．whom指人，在从句中作宾语，常可省略，不能作主语。
The boy (whom) the teacher often praises is their monitor.
老师经常表扬的那个男孩是他们的班长。
注意：(1)关系代词whom在口语或非正式文体中常可用who来代替。
The boy(who/whom/that) we saw yesterday is John's brother.
昨天我们看到的那个男孩是约翰的哥哥。
