on which和in which有什么区别

on which 和in which都是属于定语从句中介词+which/whom的结构

先来谈谈介词前行的规律

1. 介词与定语从句中的谓语动词构成短语 例如：The boy with whom I dance is handsome. 从这个例子中我们可以看出：dance 后的with提到了先行词的后面，whom的前面

2. 介词与定语从句中的先行词构成介词短语 例如：Life is a long journey in which we must experience happy and sorrow.从这个例子中我们可以看出，in a long journey是一个介词短语

所以，on which和in which的区别，其实在于on 和 in 这两个介词的具体搭配和相关短语

on which 和 in which 都可用在定语从句中 引导定语从句 修饰先行词 区别在于介词On/in 这取决于 先行词 的搭配 i can't forget the day on which we had a party.on the day i can't forget the year in which i found a job.in the year

首先你要明白which引导的是定语从句，只是所用介词的不同。
例句 先行词是 day, 意为 I joined the soccer team on the day. 在具体的某一天 用on .

下面的例句用in which
He left the house in which he was often beat by his step-father when he was a child.
he was beat by his step-father in the house.

on这个介词只是在动词需要时才用,.which 就是一个独立的关系代词,直接作主语或者宾语.
