关系副词在高考中的考点主要是：关系副词when，where，why引导定语从句，在从句中作状语，可以根据情况转换成“介词＋which”。
when(＝at/on/in/during which)
where(＝in/at which)
why＝(for which)
1. The reason why/for which you failed, I think, was that you had turned a deaf ear to your mother's advice.我认为你失败的原因是你不听你母亲的忠告。
2. He will forever remember the day when/on which he was admitted to Beijing University.他将永远记得他被北京大学录取的那一天。
