关系词
3-3：关系副词where的用法
where引导的形容词从句只用来修饰表地点的名词。我们在中学时已学到，表大地点（如城市，国家，区域）时，介词要用in；表小地点（如车站，商店，某特定的地点）时，介词要用at；表内部（在……之内）时，介词要用in；表外在（在……上面）时，介词要用on。
因此，关系副词where＝in which, on which, at which。
例：this is the city in which i met mary.
＝this is the city where i met mary.
i met him at the station,at which there were many passengers.
=i met him at the station,where there were many passengers.
（我在车站遇见他，那里有许多旅客。）
l bought a cabinet in which i could store books.
=l bought a cabinet where i could store books.
（我买了一个柜子，我可以把书放在里面。）
do you see the desk on which there is a book?
=do you see the desk where there is a book?
（你看见那张上面有本书的桌子了吗？）
