[要义详析]
一、定语从句的概念
1.定语从句:在复合句中起形容词作用,作定语,修饰名词或代词的从句叫定语从句。
2.先行词:被定语从句修饰的词叫先行词。
3.关系词:连接先行词和从句的词叫关系词。关系词指代先行词,并在句子中起连接作用,连接主句和从句,同时又在定语从句中充当成分(主、宾、表、状等)
关系词根据其在从句中所充当的成分可以分为:
(1)关系代词:在从句中作主语、宾语、表语、定语(that/which/who/whom/whose/as)。
(2)关系副词:在从句中作状语(when/where/why)。
二、关系代词的用法
1.who/whom
先行词是人,关系代词who在从句中作主、宾、表的成分。who在从句中作主语,whom在从句中作宾语,whom只能作宾语可省略。口语中who可以代替whom,也可以省略,但作介词宾语时,只能用whom。

4.whose
先行词是人或物,关系代词whose在从句中作定语。whose在从句中作定语指某人时,可以用... of whom/the+名词+of whom代替whose;指物时可以用... of which/the+名词of which代替whose。
