精品文档---下载后可任意编辑定语从句中关系副词的用法关系副词，顾名思义，是联系先行词和定语从句的词，属于副词。定语从句中的关系副词有三个：when, where 和 why，它们在定语从句中分别作时间、地点和原因状语。其句法结构如下： 表时间的名词 + when + 定语从句 when 指时间，在定语从句中作时间状语。 例句：I still remember the day when I first came to Beijing. I’ll never forget the day when I joined the army. 表地点的名词 + where + 定语从句 where 指地点，在定语从句中作地点状语。例句：The factory where his father works is in the west of the city.
