题目内容：

in which的用法
这里有一句
and then they're going to go on a world tour in which they will perform in ten different cities.我还记得以前有个什么在结尾在in的可以放到前面来也是成为in which,不过我不知道这里后面哪里可以用in
能把他的用法详细地说明一下么？听不太懂啊

优质解答

就是先行词在从句中in的宾语时用in which 嘛,你搞得这么复杂做什么.
I live in a lovely world.
the lovly word in which I live .
----
不用说细说,因为说穿了很简单:任何做in 的宾语 的词都可以改成in which定语从句.
Bejing is a big city.I was born in Bejing.In Bejing
Being is a big city in which I was born.
