定语从句详解+例句

Attributive Clause 定语从句一、定义定语从句：修饰名词或代词的从句。

换句话说，名词、代词后的从句叫定语从句。

先行词：被定语从句修饰的名词、代词、甚至词组或句子叫先行词。

关系词：引导定语从句的词叫关系词。

1关系代词：在定语从句中担任主、宾、表、定语成分2关系副词：在定语从句中担任状语成分关系词3 个功能：1.连接功能（连接先行词与定语从句）；2.担任功能（在定语从句中担任主、宾、表、定、状语）；3.替代功能（在定语从句中代替先行词）。

关系代词在定语从句中充当主语的是：who, that, which, as宾语的是：who, whom, that, which, as定语的是：whose, which先行词是人时，关系代词是：先行词是物时，关系代词是：who, whom, that, as which, that, whose, as关系副词有：关系副词=when ( 先行词为时间介词 + which / whom), where (先行词为地点), why (先行词为原因)定语从句分为两种：限制性与非限制性。

先行词与关系词之间无逗号隔开为限制性；有逗号隔开则为非限制性，且一般由 which 引导。

唯一可以置于先行词之前的定语从句由关系代词as引导。
