定语可以由形容词、代词、数词、 名词、分词、不定式、介词短语等来担 任，修饰名词。(以分词、介词短语为 例)例：A beautiful girl (形容词)The girl in red is Kate.(介词短语) The boy named Tom is my good friend .(过去分词)

The girl who has long hair is kate .

Mary is a girl who has long hair.先行词 关系代词

关系词

定语从句 关系副词

which, who, whom, Where, when,why whose, that

定语从句定义在英语中，修饰名词或代词的句子叫定语从句。

被定语从句修饰的名词或代词叫做先行词。定语从句放在先行词的后面，由关系代词或 关系副词引导。

定语从句中关系代词的用法:当先行词是物时, 用which 或that引导.当先行词是人时, 用who, whom, that引 导.

that 1.This is the only book ___ I bought last year. 2.All__________I’m going to do is that good. that 3.This is the best book ____ I have read . 4.Watch the old lady and her that dog____ are crossing the street . that 5.Which is the bike ____ you lost ?

只用that 不用which的情况1.先行词被形容词最高级或序数词修饰时

2.先行词是all,something,nothing,anything不定代 词时 3. 先行词既有人也有物时,只能用that 4.先行词是 little,few, no, all,any,only much 等 修 饰时， 5.当主句已有疑问词 who或which时，关系词用 that
