关系副词when的用法

when 既可引导限制性定语从句，又可引导非限制性定语从句。先行词是时间名词，在从句中充当时间状语，相当于“介词+which”。如：

Can you tell me the time when the film will start?—Can you tell me the time at which the film will start? 请告诉我电影什么时候开始好吗?(限制性定语从句)

I will never forget the day, when I joined the Party.—I will never forget the day, on which I joined the Party. 我入党的那一天，我永远不会忘记。(非限制性定语从句)

关系副词where的用法

where既可引导限制性定语从句，又可引导非限制性定语从句。先行词是地点名词，在从句中充当地点状语，相当于：“介词+which”。如：

This is the school where I studied a few years ago.—This is the school in which I studied a few years ago. 这就是我几年前所在读书的学校。(from www.yygrammar.com)

Let’s go to the concert, where you will find much fun.—Let’s go to the concert, in which you will find much fun. 我们去音乐演唱会吧，在那里你会找到很大的乐趣。

关系副词why的用法

why只能引导限制性定语从句，先行词只有reason一词，在从句中充当原因状语，相当于：“for + which”。如：

Do you know the reason why he is not here now?—Do you know the reason for which he is not here now?你知道他还没有来这儿的原因吗?
