in which. on which.for which.at which.of whom分别等于什么。例forwhich=why其用法是?

没有分别等于什么，具体句子具体对待

比如The room in which I was born remains the same. 这里=where

The day on which I was born is unknown. 这里 on which= when

The year in which i was born is unknown. 这里in which=when

介词选择根据前面名词，或者后面动词来确定， 而关系副词when,where根据前面是时间，还是地点来确定。

你问这个问题，说明你定语从句基本不懂，建议你找点详细资料，好好学学。

介词in which的用法是什么？

1、in which，for which，on which，at which这些都是定语从句里面，由which引导的定语从句，介词提前。

2、引导定语从句时where与in which有时可互换，有时不能互换，。

3、当“介词+ which”在定语从句中作时间、地点和原因状语时，可以用相应的关系副词when, where和why来替换。

4、where根据情况可以等于in which, at which, on which等。

5、关系副词若要换成“介词+which”只能是for which。

介词+ which和on which的区别

区别在于后面的定语从句缺少不同的状语。因为这些介词加关系代词中间的介词很多是由定语从句决定的，which指代前面的先行词。其中包含固定词组，要么和先行词构成固定搭配后在定语从句里做状语；要么和定语从句的谓语构成固定搭配做定语从句的状语。

in which：在......里。

for which：为了......；因为.....。

on which：关于......；在......上。

at which：（具体）在......（年龄/地点等等）。例如：

Select the database in which you want to compare counters.（ in which在定语从句里做地点状语）

选择您想要在其中比较计数器的数据库。

This is an emerging space in which we will likely be seeing some innovation over thecoming months.（ in which在定语从句里做地点状语）

这是一个新兴空间，关于这方面，在未来的几个月我们将能看到一些创新。.

That is the reason for which he dislikes me.（for which在定语从句里做原因状语）

这就是他不喜欢我的原因。

It would work and serve the specific purpose for which it was created, but it would do little to deliver on the original promise of SOA as it had been envisaged several years earlier. （for which在定语从句里做目的状语）

没错，它能完成一定的功能并满足最初的特定目标，但至于履行已展望多年的SOA最初承诺，它就不行了。

The material on which an autograph was signed, and whether the star was living ordead, could have as much of an impact as who signed it.（on which在定语从句里做地点状语，sign on：在......签字）

有明星亲笔签名的那些东西和给这些东西签名的人物具有同样大的影响力，不管这些明星是活着还是已经死了。

Where the analysts seem to have gone off the rails last year is in the price-to-earnings multiples on which they based their predictions.（on which在定语从句里做地点状语，词组base......on......：把什么建立在.....上）

然而，分析师们当时似乎在市盈率倍数这个他们赖以进行预测的关键数据上出了岔子。

Study of the bones of these cattle from ancient times shows the ages at which the animals were killed.（在定语从句里做时间状语，at the age of：在....岁时）

对于这些远古时期驯化牛骨骼的研究结果告诉了我们这些家畜宰杀时的年龄。

which,in which,on which,for which ,of which 有什么区别，在定语从句中怎么用？

选A。

which在限制性定语从句中就是指先行词，如题中的which就指先行词the day,在从句中作动词forget的宾语。

"介词+which"不能只从意思上区别，介词的选择主要有3方面

1，考虑先行词与介词的固定搭配。

This is the farm on which he is working .

on the farm 是固定搭配。

2，考虑句意的需要。

This is a factory into which he wants to go .

go into the factory .

He is one of my friends with whom i am living .

live with sb .

3, 考虑 定语从句谓语动词的固定短语所需什么介词。（这种情况尤为多些）

This is a book in which i am interested .

be interested in sth .

初三英语 (1) in which (2) on which （3） at which （4）by which (5) with which (6)about which 分别

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

with wcich/in which/on which/by which/ at which的意思？

in which +地点名词表示“在。。。里面”which引导定语从句，是起修饰作用。

in which+方式名词“用。。。方法/手段”

from which引导具体地点的定于从句

by which通常是表示的采用的....方式

of which是比较特殊的限定性定语从句 of是根据主句中的动词决定的

which和in which的区别

区别一：

which是关系代词或关系形容词,作为代词用作主语或宾语,作为形容词用作定语；

“介词短语+ which”属于副词性,只能用作状语.如：

This is my house, (which) is small and old.

这是我的房子,它又小又旧.[主语]

He is studying economics, (which subject) is very important.

他正在学习经济学, 该学科是很重要的.[定语]

This is the subject (on which) she spoke.

这就是她谈到的话题. [状语]

区别二：

which 用于定语从句，作关系代词，在句中要做成分

in which 用于定语从句，作关系副词，在句中不做成分，in which=where

好了，关于“in which on which at which的区别”的话题就讲到这里了。希望大家能够通过我的讲解对“in which on which at which的区别”有更全面、深入的了解，并且能够在今后的工作中更好地运用所学知识。
