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。

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。

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1．关系代词的基本用法（见下表）：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。

关系代词的用法。
who的先行词是人；when的先行词是时间名词，在从句中作状语；what不能引导定语从句，此处先行词是museum，是事物，应该用关系代词which替代museum，在从句中作visit的宾语，故选C。
