定语从句中 which where in which这三者怎么用?

（一）which是关系代词,其指代的先行词是物,which在从句中作主语或宾语,在从句中充当宾语时可以省略.which可以换成that.如：
This is the desk which/that/-- I bought yesterday.这是我昨天买的桌子.（which/that/-- I bought yesterday是定语从句.which/that在从句中作宾语,可省略）
The books which/that are on the desk are mine.桌子上的书是我的.（which/that are on the desk是定语从句,which/that 在从句中作主语,不能省略.）
（二）where是关系副词,其指代的先行词是地点名词,where在从句中作地点状语.如：
This is the house where I grew up.这就是我在此长大的房子.（where I grew up是定语从句）
（三）in which是介词加关系代词.in which有两种用法：一是替换关系副词where,一是替换指代the way的关系副词that.如：
This is the house in which I grew up.（in which I grew up是定语从句）
The way that/ in which she looks at you is strange.她看你的方式怪怪的.（that/ in which she looks at you 是定语从句）

1.which 疑问代词
例句：Football is a game which is liked by most boys。足球是一项大多男孩都喜欢的运动。
主句Football is a game 是一个完整句子，which is liked by most boys修饰的是game,修饰的是个名词，所以用which指代game.，which 在从句中作主语，所以也得用whic...
