2.where指地点，在从句中作地点状语。它的先行词常有：place, spot, street, house, room, city, town, country等。
This is the hotel where they are staying.
I forget the house where the Smiths lived.
3. why指原因或理由，它的先行词只有reason。如：
That is the reason why he is leaving so soon.
（三）使用关系副词应注意下列几点：
1. 这三个关系副词在意义上都相当于一定的介词+which结构：
when = on (in, at, during…) + which;
where = in (at, on…) + which;
why = for which. 如：
I was in Beijing on the day when (=on which) he arrived.
The office where (=in which) he works is on the third floor.
This is the chief reason why (=for which) we did it.
2. 当先行词是表时间的time, day等和表地点的place, house等时，一定要注意分析从句的结构，如果缺少主语或宾语时，关系词应该用which或that, 缺少时间状语或地点状语时，才能用when或where，试比较：
I’ll never forget the day when my hometown was liberated.
I’ll never forget the days which/that we spent together last summer.
His father works in a factory where radio parts are made.
His father works in a factory which/that makes radio parts.
