1、关系副词兼有副词与连接词两种作用，在不及物动词的连接中要求用关系副词。
2、关系副词所引导的形容词子句用于修饰主要子句中的某一名词或代名词，被修饰的词称作先行词，关系副词要放在先行词之后。
例如：关系副词when在定语从句中用作状语，表示时间，用以修饰表示时间的先行词。
3、关系副词主要有三个，即when，where，why。此外that也可代替关系代词引导代词句子。
4、关系副词=preposition(介词)+relative pronoun(关系代词)
where=in which，when=on which，why=for which，这些关系副词在从句中做状语。
例如：
（1）Would you please tell me the way to the zoo? 你能告诉我去动物园的路吗?
the way是先行词。
（2）This is the place where(that) I first met her. 这是我第一次见到她的地方。
在口语中that可以充当关系副词，代替when，why，how，只有先行词是the place时，才可代替where。
5、time，day，year，place，house，reason，way等作先行词时可以被省略，其后的子句不再是形容词子句，而变成名词子句或副词子句。
（1）中文：这是他出生的地方。
This iswhere he was born. （where he was born是名词子句。）
This is the place where he was born. （where he was born是形容词子句。）
（2）中文：我将在第一次见到她的地方见她。
I'll meet her at the place where I first met her. （where I first met her是形容词子句。）
I'll meet her where I first met her. （where I first met her是副词子句。）
6、关系副词有限定用法，指的是关系副词引导的形容词子句只修饰先行词。
We were very happy in those days when we studied in school. 我们在学校里上学的那些日子里很快乐。
7、关系副词有补述用法，即关系副词引导的是对等子句而不是形容词子句，主要用于对主要子句中的不足之处加以补充，前面都要加逗点与主要子句分开。
Tom got married the day before yesterday，when it was his birthday too.汤姆前天结婚了，那天也是他的生日。
8、wherever，whenever，however是复合关系副词，表示"不论"，引导一个修饰主要子句里的动词的副词子句，可加强语气或表示让步。
