英语问题求解答在定语从句中介词加which等于个关系副词，什么时候不等呢？举个例子！谢谢啦！！

Answer 1

严格地说 介词加which 并不完全等于关系副词

介词加which 比 关系副词 表达的意思 具体
如 this is the desk on which i put my books.
this is the desk in which i put my books.
上面两句 都可以 用where 代替 on which 或in which. 但表达 就不具体。
一般来说 介词加which 引导定语从句 并且在定从中 作地点时间原因状语时 ，可以用关系副词 代替。
但 如果 介词加which 引导定从 不是在定从中作上述状语 而是作定语 或 方式状语时 就不能 用关系副词 代替
如 this is the house of which the windows are broken.
或this is their house ，the windows of which are broken.

Answer 2

of which就不等于关系副词
如：
I have taken ten books to the school, two of which are for you.
介词+which表示时间，地点时，一般可以换成when或where的。

Answer 3

This is our classroom in which we have classes.
This is our classroom where we have classes.

Here is the key with which you can open the door.

前面的in which和where可以替换，但后面的句子就不可以替换了。
一般情况下，大多数是可以替换的，但还是要具体分析句子结构的。希望能帮到你！

Answer 4

当介词和从句里的动词可以构成复合谓语的时候是不等于关系副词的。

Answer 5

in which=where in which 用于定语从句，作关系副词，在句中不做成分，in which=where
This is the city which I lived in.或 This is the city in which I lived. 动词为及物动词时不等
