at which,in which,on which,for which,by which,from which 分别等

其实就是一般的限定性定语从句
至于前面的介词取决于主句中的动词
比如this is the pen by which i wrote compisition
不能呆板于介词＋which是何用法

这些都是介词+which的用法,其实,最主要的差别还是在介词上,而介词呢,又是跟着后面的状语走的.
比如,on which I have spent two hours,不好意思,可能我这样造句有点牵强,但是,事实上,我只是想让你知道,这里有个词组是,spend time on ,而且其实,这句话也可以变成,which I have spent two hours on
by的话,词组也是很多的,比如 catch up with sb.by doing
to的话,offer sth to,但是,我觉得一般是to whom比较多
from,borrow from ,learn from
in,这个比较多,一般性,只要是个地点,考察的时候多数用in
with,这个词的话,大多数表示伴随,不太好说,要看具体情况
for,pay for 用得比较多
of的话,表示.的,比较多,通常都是和both of,neither of 一起用的

at which在功能上等于where,但就本题而言只能选at which.因为at which I have eaten such wonderful meal是一个插入语,where固然可以引导,但是由于前面有了一个逗号,就只能用at which了.我难以相信我曾经在里面美美地吃过几顿大餐的饭店就要关张了.非限制性定语从句是高一英语的一个重点,如果你是高中生的话,老师应该讲过了吧?主要就是先行词+（,)+介词+which或者是就先行词+（,）+which,它和定语从句的最显著区别一个是有逗号,一个是非限制定语从句总是有which.这东西比较复杂,也不是几句话能讲清楚的

（1）因为where先行词在定语从句中是当成“地点状语”来理解的,所以,等效替换的时候其句子成份的功能应该一样,而介宾短语要么作“状语”要么作“补语”,也就说,介宾短语可以充当“状语”的功能.
（2）where在用你说的那几个介宾短语替代时候,主要看2点：一点就是看对象（或意思）,其差别就是介词in/on/at/to的差别,表示的地点、位置不同（如in this room等）；另一点就是看一些常用的介词搭配（本质上还是看意思,如 be interested/involved/absorbed 等过去分词习惯跟in,表示在什么里面）.
同样地,这个等效替代方法也适用于when、why、how等表示时间、原因、方式/状态的“状语”.

which 是定语从句的先行词,用at还是with 取决于修饰那个which指代的词,比如说this is the house,at which my girlfriend and i stay.i like the game,with which i am familiar.

which 前面用in 、for、on还是at,取决于which指代主语中的那个词.
例如：
The court is one of the few institutions in which people have to do some elitethinking.
(在像最高法院这类为数不多的机构里,人们必须做一些精英化的思考.)
这里in which=in the court, in the court 你能理解吧,根据句意和语法肯定不能用for the court 或on the court 和at the court

区别不在本身
得看你用语句子的时候后面的动词后跟着带的是什么动词,这个动词又是跟的什么介词
比如at which he can stay

你看他们都是定语从句先行词吧,所以which前面的介词其实都是后面从句的介词提前的.
你先把从句中缺什么成分找出来,把which所代表的主句中的词带到从句中的缺空处,你就可以根据语义理解需要什么介词使从句完整,你根本不需要知道他们跟which放在一起是什么意思.比如by：可以表示时间,方式,被动什么的

这个是根据句中前面的具体词来决定是in which,at which,for which或at which的,因为前面的名词、动词等都有相应的搭配词,也有时候地点,用at,是原因等用for,像你举得这个例子是in which是因为前面的the same way ,in the same way 是固定搭配,表示用同样的方式

where 可以引导所有类型的从句,只有在它引导定语从句时 才可能
和in which 替换,其他时候都不行.这取决于先行词与介词的搭配：
This is the village where / in which I was born.
This is the village where / from which he joined the army.
This is the shool gate where / at which we met the other day.
I was born in the village.
He joined the army from the village.
We met at the school gate the other day.
at which是不是=when：是否选择when还是使用at which是有效性错误的问题,时态才是关键,
但是日常做题目的时候可以这样理解这个考点：时间状语后面比如year,age,通常用when修饰,但是 介词+which的修饰更优,往往更清晰.
for which是不是=why：很抱歉 我没查到他们的区别 而我自己又认为他们没什么区别 他们可以互换
why是关系副词 ,而for which 是介词＋which结构
关系副词含义相当于＂介词＋which结构＂,因此常常和＂介词＋which＂结构互换
其中
关系副词有：when,where ,why
介词＋which结构有：
when =in/on which ,where=in/at which ,why =for which
对了 是在定语从句中的...

首先你得明白两个词的词性：
where 是个方位副词
which 是个疑问代词或者是引导连词.
where is my room?(adv)
which is my romm?(proun)
上面是单句,下面看从句：
He asked where we should go.是去的不确定的方位或者地点,而且在从句中充当的是个状语的成分,只能用where.
He asked me which color i like.
作为是一个疑问代词,而且有相对的固定的领域：颜色选择.从句和主句都却少一个宾语.疑问副词where是不能充当这个成分的.
在来看看你说的可以替换的情况：
前提要搞清楚：他们的替换只能在表示方位地点的时候才可以,而且是替代句子中的定语的时候才会出现：地点状语从句中,where 只能指一个模糊的地点,而which则有一个定向的限定区域,意思不近相同：
例如：
I didn't know where he lived in the village.
I didn't know in which village he lived.
再如：
where he comes from is a secret
which province/state he comes from is a secret.
定语从句中：
it is the shelf where i put my book.
it is the shelf on which i put my book.
就可以替换,意思只能说是十分相近而已

语从句中介词前置于引导词,at which为在哪里（小地方）,in which为在哪（大地方）,on which（在哪天）

from thefreedictionary.com:



at which:
At which station should I change trains?


in which ...:
My father may have to go into hospital,in which case he won't be going on holiday.


for which:
The documents for which they were searching have been recovered.


这里的at,in (case),for都是需要跟后面句子搭配的,即：
I change trains AT some station.

in this/that case 是个固定搭配.
They were searching FOR the documents.

on which.the day对应which.I join the league 在具体的某一天用on.后半句展开来就是 I join the league on the day.which 作the day的定语.on the day变成on which.
还不明白可以百度HI

根据句中的谓语动词辨别就可以了
只是介词前置而已
也就是说前面的介词取决于主句中的动词
很简单
如
in which
The building in which he studied was very old.
实际上是study in the building将in前置
这句子可以分成两句
He studied in the building.
The building was very old.
限制性定语从句就是把这两个句子合成一句
同理 for which
The picture for which he paid $1,000 was once owned by a duke.
pay for 将 for前置

（A） 如果你知道了铅球的精确方向以及它在离开奥运会运动员的手时速度的大小,那么你就可以用一个线性方程去精确地预测它能飞多远.
at which a shot put 是定语从句 先行词是 direction and velocity
也就是 a shot put at the direction and velocity
（B）at which the term occurs是定语从句 先行词是 the list of positions
也就是 the term occurs at the list of positions
