关系副词的意思相当于“介词+which结构”，在定语从句中做状语的成分，如下图

　　黄色字体为关系副词

　　黄色字体为关系副词

　　我们可以用上一节说到拆分法来分析几个句子，如下：

　　1.He will always remember the day when/on which his father returned from America.

　　他将永远记得父亲从美国返回的那一天

　　拆分后：

　　He will always remember the day.

　　His father returned from America on the day..

　　2.This was the time when/at which she left for Beijing.

　　这就是她动身去北京的时间。

　　拆分后

　　This was the time.

　　She left for beijing at the time.

　　3.I don't know the reason why/for which he didn't come to the meeting yesterday morning.

　　我不知道他为什么没有参加昨天上午的会议。

　　I don't know the reason.

　　He didn't come to the meeting yesterday morning for the reason.

　　重要提示：在when、where、why关系副词引导的英语定语从句中，只会出现when、where、why或on which、at which、for which等等，绝对不会出现on when、at where、for why这种情况，因为关系副词引导的定语从句只能起状语作用，既不能做动词的宾语，也不能做介词的宾语。
