高一英语(牛津译林版)必修一定语从句

定语从句一、基本概念1．定语从句：在一个主从复合句中修饰某一个名词、代词或修饰整个主句的从句叫定语从句。

换句话说，定语从句就是用来作定语的句子。

2．先行词：被定语从句修饰的名词或代词叫先行词。

先行词前一般用the ，但在指“一个”概念时可用a , an 。

3．关系代词/ 关系副词：连接先行词和定语从句的词叫关系词，根据其在从句中作用分为关系代词或关系副词。

若先行词在从句中作主语、宾语和定语等，应用关系代词引导定语从句；若先行词在从句中作时间状语、地点状语和原因状语等，应用关系副词引导定语从句。

4．定语从句的位置：一般紧跟在先行词后面。

但有时因句子结构的需要，定语从句和先行词被某些成分隔开。

5．引导定语从句的关系词分为二类：关系代词：that, which ,who, whom ,whose , as关系副词：when, where, why二、基本用法2．使用关系代词时应注意的几个问题：a. 在以下几种情况下只使用that不用which。
