onwhich _生活经验

in which ， for which ， on which ， at which有什么区别，怎么使用？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）。[qū bié]区别（汉语词语）编辑区别是一个汉语词汇，有区分;辨别的意思。
英语问题， on which 和 in which 有啥区别 ?关系代词which前面的介词不同啊，一定引起用法的不同。

in which ， for which ， on which ， at which有什么区别，怎么使用，用法in which ， for which ， on which ， at which的区别、使用、用法：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 。拓展资料in which1、His book foregrounds three events in which police relations with the media were central.他的书重点讲了3个事件，以警察和媒体的关系为中心展开。2、Two major areas in which mentally retarded children require help are memory and attention.智障儿童主要是在记忆力和注意力这两方面需要帮助。3、I also used to love the smooth way in which the foreigner operated. 我也曾经喜欢那个老外平稳流畅的操作方式。4、It is the sixth month in a row in which imports have fallen. 这是进口量持续下降的第6个月了。5、That is a fair approximation of the way in which the next boss is being chosen. 那和下一任老板的选任方式相当类似。for which1、Ours could well be the last generation for which moviegoing has a sense of magic. 我们这一代很可能是认为到电影院观影具有一种魔力的最后一代人了。2、The restrictions he imposed pertained to the type and height of buildings and the activities for which they could be used 他限制的是建筑物的种类和高度以及它们的用途。3、She's got a part-time job for which she earns 2,000 yen a month. 她有一份月收入2,000日元的兼职工作。4、How can anyone blame her for actions for which she feels herself to be in no way responsible? 她认为自己对这些行动不负有责任，别人怎么还能因此而责备她呢？5、The market for which they are competing is still unformed. 他们角逐的市场尚未成形。on which1、This is the basis on which our bilateral relations can and should continue to develop.这是两国关系应得到继续发展，并可能得到继续发展的基础。2、Roberts has spent much of his working life collating the data on which the study was based罗伯茨的很大一部分工作时间都是在核对研究所需的数据。3、We will then have a firmer foundation of fact on which to build theories 那样我们将会获得一个建立理论所需的更为牢固的事实基础。4、Audiences were going to be polled on which of three pieces of contemporary music they liked best 将对观众进行民意调查，询问他们在3部当代音乐作品中最喜欢哪一部。5、All the light bars were turned on which filled the room with these rotating beams of light所有灯条都打开了，满屋都是旋转的光柱。
on which 和in which 都有什么区别？怎么用的？which指代物，一个物品
最为常用。
in/on
which=where
视具体地点而定、
for
which=why
表示原因
of
which
指代在……（可能是一个集团等）之中。
在非限制性定从中， which最为常用，可以指代一整句句子而非一个东西或单元。

which和in which用法的区别

文章插图

which和in which用法的区别为：意思不同、用法不同、词性不同。一、意思不同1、which：哪一个，哪一些。2、in which：在其中。二、用法不同1、which：which用作关系代词，可引导限制性定语从句或非限制性定语从句，引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that ，有时还可引导不定式短语从句。2、in which：in which用于定语从句，作关系副词，在句中不做成分， in which=where 。三、词性不同1、which：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。2、in which：“介词短语+ which”属于副词性，只能用作状语。
in which 和on which的区别和用法？【onwhich】in which:在......里面；on which:在......的上面，或具体时间的某一天on which 和 in which 都可以用来引导定语从句，修饰先行词，区别在于介词on/in 这取决于先行词的搭配比如:I can't forget the day on which we had a party.这个句子，先行词是day ，原本的搭配是on the day.I like the room in which there are many toys.这句话的先行词是room ，词组搭配是in the room 。例句：1.The school (that/which) he once studied in is very famous. = The school in which he once studied is very famous. 2. I have a dresser in my bedroom, which there are many cosmetics on. = I have a dresser in my bedroom on which there are many cosmetics. 固定搭配：The plane may be several hours late, in which case there’s no point in our waiting. (固定搭配：in the case) The little creature in which scientists are interested is known as ET.(这里"be interested in"是词组原因) 例题：I can’t believe that the restaurant, ______ I have eaten such wonderful meal, is going to be close down.A. whereB. at whichC. about which【解答】选B 。这个是非限制性定语从句， 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。”非限制性定语从句主要就是先行词+逗号“ ， ”+介词+which或者是先行词+逗号“ ， ”+which ，它和限定性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有which 。
in which ， for which ， on which ， at which有什么区别，怎么使用，用法这些都是定语从句里面，由which引导的定语从句，介词提前。
in which可以翻译成在„„里面 for which可以翻译成为了„„目的
on which可以翻译成在„„的上面，或具体时间的某一天 at which可以翻译成在„„里面或在„„上面

这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。
例如：
(1) The school (that/which) he once studied in is very famous. = The school in which he once studied is very famous.
(2) Tomorrow I will bring here a magazine (that/which) you asked for.= Tomorrow I will bring here a magazine for which you asked.
(3) I have a dresser in my bedroom, which there are many cosmetics on. = I have a dresser in my bedroom on which there are many cosmetics. (4)The dumpling House which he often has dumplings at is very popular. = The dumpling House is very popular, at which he often has dumplings.

当然这只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。例如：
The plane may be several hours late, in which case there’s no point in our waiting. （固定搭配：in the case)
The speaker paused to examine his notes, at which point a loud crash was heard. （固定搭配：at the point)
Ten years of hard work changed her greatly, for which reason he could hardly recognize her at first sight.（固定搭配：for the reason）
The film at which I fell asleep was very boring.
（Here "at which" is based on "fell asleep at the film"因为电影无聊而睡觉。） The little creature in which scientists are interested is known as ET. （这里"be interested in"是词组原因）
This is the book for which he is looking.
（即等于This is the book which he is looking for ，这主要是因为look for 这一短语）

in which ， for which ， on which ， at which有什么区别，怎么使用，用法in which, for which, on which, at which的不同用法

1)这些都是定语从句里面，由which引导的定语从句，介词提前。下面这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。

①in which可以翻译成在……里面

The school (that/which) he once studied in is very famous.

= The school in which he once studied is very famous.

②for which可以翻译成为了……目的

Tomorrow I will bring here a magazine (that/which) you asked for.

= Tomorrow I will bring here a magazine for which you asked.

③on which可以翻译成在……的上面，或具体时间的某一天

I have a dresser in my bedroom, which there are many cosmetics on.

= I have a dresser in my bedroom on which there are many cosmetics.

④at which可以翻译成在……里面或在……

The dumpling House which he often has dumplings at is very popular.

= The dumpling House is very popular, at which he often has dumplings.

2)当然第一点只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。

①The plane may be several hours late, in which case there’s no point in our waiting.

(固定搭配：in the case)

②The speaker paused to examine his notes, at which point a loud crash was heard.

(固定搭配：at the point)

③Ten years of hard work changed her greatly, for which reason he could hardly recognize her at first sight.

(固定搭配：for the reason)

④The film at which I fell asleep was very boring.

(Here "at which" is based on "fell asleep at the film"因为电影无聊而睡觉。)

⑤The little creature in which scientists are interested is known as ET.

(这里"be interested in"是词组原因)

⑥This is the book for which he is looking.

(即等于This is the book which he is looking for ，这主要是因为look for 这一短语)

关系副词与“介词+which”的区别

引导定语从句时where与in which有时可互换，有时不能互换，注意以下几点：
一、关系副词与“介词+which”互换的情形
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。
1. when根据情况可以等于in which, at which, on which等。如：
The day when (=on which) she arrived was Thursday. 她到的那天是星期四。

2. where根据情况可以等于in which, at which, on which等。如：
This is the hotel where ( =in which / at which) they were staying. 这就是他们当时住的旅店。

3. 关系副词若要换成“介词+which”只能是for which 。如：
The reason why (=for which) I came here was to be with my family. 我到这里来的原因是要跟我的家里人在一起。

inwhich 等于where,那on which等于where吗？关系副词都等于一个适当的介词＋which ，在从句中作状语
When=in/at/on/…+which;
Where=in/at/on/…+which;
Why=for /…+which
1.Do you still remember the day when(on which) we went to visit the museum together?
2.This is the factory where(in which)my father once worked.
3.This is the reason why(for which) he was late.

in which at which on which 都等于where吗你很单纯.其实不是你这样想的.比如说一个句子在从句的主语后有pay则用pay for他配因此要用for which.其它的类推.说白了要看介宾结构的介词而定.像这样的还有piont用in which标定点.你可以去看看谓语动词的搭配.

in which ,on which等于where吗?m_connect=0;Sleep(500);GetDlgItem(IDC_BUTTON_CONNECT)->SetWindowText("连接");VCI_CloseDevice(m_devtype,m_devind);return;}

“in which”等于“where” ， “on which”等于“where”吗？关系副词都等于一个适当的介词＋which,在从句中作状语
When=in/at/on/…+which;
Where=in/at/on/…+which;
Why=for /…+which
1.Do you still remember the day when(on which) we went to visit the museum together?
2.This is the factory where(in which)my father once worked.
3.This is the reason why(for which) he was late.

in which=where 那on which=?定语从句中
介词+which= where
要看具体语境..
in which和where都是壮语,在从句中..in\on which可以代替where 指代从句中的地点

on which和in which有什么区别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

in which ， for which ， on which ， at which有什么区别，怎么使用，用法这些都是定语从句里面，由which引导的定语从句，介词提前。
in
which可以翻译成在„„里面
for
which可以翻译成为了„„目的
on
which可以翻译成在„„的上面，或具体时间的某一天
at
which可以翻译成在„„里面或在„„上面
这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。
例如：
(1)
The
school
(that/which)
he
once
studied
in
is
very
famous.
=
The
school
in
which
he
once

is
very
famous.
(2)
Tomorrow
I
will
bring
here
a
magazine
(that/which)

=
Tomorrow
I
will
bring
here
a
magazine
for
which
you
asked.
(3)
I

bedroom,
which
there
are

=
I
have
a
dresser
in
my
bedroom
on
which
there
are
many
cosmetics.
(4)The
dumpling
House
which
he
often
has
dumplings
at
is
very
popular.
=
The
dumpling
House
is
very
popular,
at
which
he
often
has
dumplings.
当然这只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。
例如：
The
plane
may
be
several
hours
late,
in
which
case
there’s
no
point
in
our
waiting.
（固定搭配：in
the
case)
The
speaker

examine
his
notes,
at
which
point
a
loud
crash
was
heard.
（固定搭配：at
the
point)

years
of
hard
work
changed
her
greatly,
for
which
reason
he
could
hardly
recognize
her
at
first
sight.（固定搭配：for
the
reason）
The
film
at
which
I
fell
asleep
was
very
boring.
（Here
"at
which"
is
based
on
"fell
asleep
at
the
film"因为电影无聊而睡觉。）
The
little
creature
in
which
scientists
are
interested
is
known
as
ET.
（这里"be
interested
in"是词组原因）
This
is
the
book
for
which
he
is
looking.
（即等于This
is
the
book
which
he
is
looking
for ，这主要是因为look
for
这一短语）

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。
in which 可以翻译成在......里面
for which 可以翻译成为了......目的
on whch 可以翻译成在......的上面
at which 可以翻译成在.....里面或在.....上面
这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的
例如 (1) The school (that/which) he once studied in is very famous."
= The school in which he once studied is very famous.　
(2) Tomorrow I will bring here a magazine (that/which) you asked for.
= Tomorrow I will bring here a magazine for which you asked.
(3) I have a dresser in my bedroom, which there are many cosmetics on.
=I have a dresser in my bedroom on which there are many cosmetics.
（4 ) The dumpling House which he often has dumplings atis very popular.
=The dumpling House is very popular, at which he often has dumplings.
当然这只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。
例如 The plane may be several hours late,in which case there's no point in our waiting.
（固定搭配：in the case)
The speaker paused to examine his notes,at which point a loud crash was heard.
( 固定搭配：at the point)
Ten years of hard work changed her greatly,for which reason he could hardlyrecognize her at first sight. (固定搭配：for the reason)

which,in which,on which,for which ,of which 有什么区别，在定语从句中怎么用？主要是看后面状语的搭配

比如， i
live
in
guangdong,in
which(=where)
crops
grow
here.

这里后面的意思应该是， crops
grow
in
guangdong
,所以用in（地点）

i
caught
the
bus
,on
which
i
met
my
teacher.

这里后面的意思应该是i
met
my
teacher
on
the
bus,所以用on（地点）

i
like
,by
which
i
improve
my
english

这里应该是
i
improve
my
english
by
reading
english.所以用by（方式）

i
like
skiing,from
which
i
can
get
a
lot
of
happiness.

这里是
i
can
get
a
lot
of
happiness
from
skiing 。所以用from

做这种题，你先看看后面那个从句里要搭配什么样的介词，做熟了就容易了。

at which in which on which三者有什么区别?能否从地点、时间多个角度解释,这要看句子的,主要是看at,in ,on,你要是这几个单词知道怎么用的话,其实加上which也一样

in which ,for which , on which你好
in which, for which, on which, at which的不同用法

这些都是定语从句里面，由which引导的定语从句，介词提前。

in which可以翻译成在……里面
for which可以翻译成为了……目的
on which可以翻译成在……的上面，或具体时间的某一天
at which可以翻译成在……里面或在……上面

这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。

例如：
(1) The school (that/which) he once studied in is very famous.
= The school in which he once studied is very famous.
(2) Tomorrow I will bring here a magazine (that/which) you asked for.
= Tomorrow I will bring here a magazine for which you asked.
(3) I have a dresser in my bedroom, which there are many cosmetics on.
= I have a dresser in my bedroom on which there are many cosmetics.
(4)The dumpling House which he often has dumplings at is very popular.
= The dumpling House is very popular, at which he often has dumplings.

当然这只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。
例如：
The plane may be several hours late, in which case there’s no point in our waiting.
（固定搭配：in the case)
The speaker paused to examine his notes, at which point a loud crash was heard.
（固定搭配：at the point)
Ten years of hard work changed her greatly, for which reason he could hardly recognize her at first sight.（固定搭配：for the reason）
The film at which I fell asleep was very boring.
（Here "at which" is based on "fell asleep at the film"因为电影无聊而睡觉。）
The little creature in which scientists are interested is known as ET.
（这里"be interested in"是词组原因）
This is the book for which he is looking.
（即等于This is the book which he is looking for ，这主要是因为look for 这一短语）

例题：1. I can’t believe that the restaurant, ______ I have eaten such wonderful meal, is going to be close down.
A. whereB. at whichC. about which
【解答】选B 。这个是非限制性定语从句， 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。”非限制性定语从句主要就是先行词+逗号“ ， ”+介词+which或者是先行词+逗号“ ， ”+which ，它和限定性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有which 。

2. Wind power is an ancient source of energy ______ we may return in near future.
A. on whichB. by whichC. to whichD. from which
【解答】选C 。return to其实，应该来说，就是一个固定搭配了，解释为回归到，但是呢，如果要说意思的话，也是说得通的，就是把句子换一换语序你就可以看出来了。“we may return to wind power in near future.”也就是说，看到prep.+ which这种形式，就可以直接把它扔到动词后面，然后在进行选择，看缺少哪个介词。

3. We have gathered nearly 100,000 quilts, _____up to half have gone to flood-hit areas.
A. with whichB. in whichC. for whichD. of which
【解答】选D 。这里的which指的是， nearly 100,000 quilts（被褥），也就是说，后半句的主语是在这nearly 100,000 quilts里面的up to half 。

例：I don’t know the reason why/for which he did it.
The reason why/for which he was fired was not clear.

There are many countries in Asia, of which China is the largest one.
亚洲有很多国家，中国是最大的一个。

附：whose和 of which的区别

1. 关系代词whose ，引导定语从句时，既可指人，又可指物，在从句中只能作定语；of whom只能指人；of which只能指物，有时whose可以与of whom和of which互换使用。如：

The girl whose hair is golden is from England. 头发金色的那个女孩是英国人。

The house whose doors(of which the doors) are green is an office building. 门是绿色的那座房子是办公楼。

2. “介词 + whose +名词”引导定语从句。如：

I love my motherland, for whose good future I will work hard. 我爱我的祖国，为了她美好的未来我要努力工作。

3. 在下列情况下，一般只用of whom和of which 。

(1) 定语从句的主语是few, little, some, most, many, much等时，一般只用of whom和of which 。

In the room are lots of people, many of whom I don’t know. 房间里有很多人，很多人我不认识。

He has a lot of story-books, a few of which I have never read. 他有很多故事书，有几本故事书我还从未看过。

(2) 定语从句的主语是数词、形容词的最高级时，一般只用of whom和of which 。如：

The old man has three children, two of whom are college students and one of whom is a manager. 那个老人有三个小孩，其中两个是大学生，另一个是经理。

(3) 定语从句的主语是all, none, both, neither, each等不定代词时，一般只用of whom和of which 。如：

There are fifty students in our class, all of whom are working hard. 我们班有五十个学生，所有这五十个学生学习都刻苦。

He planted two trees last year, both of which are growing well. 去年他栽了两棵树，这两棵树都长得好。

(4) 在定语从句中作表语的定语时，一般只用of whom和of which 。如：

He has three brothers, of whom Li Lei is the youngest one. 它有三兄弟，李雷是他们中最小的一个。

There are many countries in Asia, of which China is the largest one. 亚洲有很多国家，中国是最大的一个。

(5) 形式不同。如：
The housewindows face south is our reading-room.
A. of whichB. whoseC. whichD. its
【解答】此题正确答案是B ，不能选择A 。选择of which时应在名词前加上定冠词the ，也就是名词前有the就只能用of which 。如果名词前没有冠词，就用whose 。若上题改为The housethe windows face south is our reading-room ，则此题只能选A不能选B了。

(6) of which除了可以表示所属关系外，还可以用来表示整体的关系，而whose则不能。例：
He borrowed a book of which the author was a peasant.
In Barcelona the Chinese team got 16 gold medals, of which 12 were won by women.
第一句中的of which就可以用whose来代替，因为这个句子中of是用来表示所属关系的。可改写成：He borrowed a book whose author was a peasant. 而第二句中的of which不能用whose代替，因为这个句子中的of不是表示所属关系，而是表示整体与部分的关系。

(7) 引导非限制性定语从句多用whose ，而很少用表示所属关系的介词of加上关系代词which 。如：
There is a mysterious lake at the foot of the hill, whose depth has never been measured. 山脚下有个神秘的湖，其深度从未被测量过。
如介词of不表示所属关系，而是用来表示整体与部分的关系，此时就经常引导非限制性定语从句了。如：
There are 102 elements found in nature, of which most are metals.
The story about Long March, of which this is one example, are well written.

I’d like a car whose front lights are big and round.
I’d like a car, the front lights of which are big and round.

The book, the cover of which is broken, is not mine.
The book, whose cover is broken, is not mine.

定于从句中by which ， for which,at which ，分别怎么用，什么意思要看是什么丛句，先行词从属于哪类，一般that的用途比较广泛，可以引导宾语从句主语从句等在句子中不做成分， which
where
when
whom
whose
一般多用来引导状语从句， which在句子中一般代指物时使用who在代指人时使用where在代指地点时使用when在代指时间时使用，要看具体引导的是地点状语从句或是时间状语从句等具体使用，其中on.in
which的用法和where相同属于介词加状语的形式，类似还有atwhich的用法法， whom因为其属于宾格虽偶一在句子中只做宾语，常可以喝who互换，但是who使用的更加广泛， whose引导所有格的形式，要看从句中具体的从属关系。

请问on which,by which, to which, from which, in which, with which,in which, for which,of which的区这些都是介词+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
如果，你有问题，再叫我吧，我尽量快快回答你哦，希望你搞得明白。

本人急求in which.on which . by which . with which. for which . of which 的用法解析要绝对详细 ...第一步, 要先了解 in, on, by, with, for, of 的用法/意思
先学会介词(Perposition)

加上which 并不是片语 (片语: 一个动词加介词变成了另外一个意思。例如: watch out (小心) /look after 照顾/ look at (看)

第二再学代名词(Pronoun)

第三这就可以学by which, in which 的用法

i) for example, To provide the means by which civcil disputes can be resolved in accordance with principle of fairness and justice.

其实这是两句句子合成为一句:
a) To provide the means in accordance with principle of fairness and justice.
b) Civil disputes can be resolved by the means.

on which/in which/at which/of which/for which /by which /with which 的意思，区别，用法给你推荐一个网站爱词霸http://www.iciba.com/on/
输入on in ,at ,of ,for ,by ,with.等，它们的区别和用法写的很清楚。希望能帮到你。

The car ---he paid $40,000 is made in Japan A.on which B.by which C.for which D.with which 求翻译选C 。
这是pay for sth 的被动语态，因为car是被付款，所以是be paid for 。
for which 是which 引导的定语从句，修饰前面的the car 。which在这里指代car 。
翻译：他花40000美金买的那辆车是在日本制造的。

不妨也试试用以下的角色来理解
which
方面
这主要与句中的
(1)
不及物动词所用的介词
或
(2)
或其它的介词
有关
例子
(1)
的例子
John
liked
the
book.
Mary
was
sitting
on
the
book.
留意
sitting
这个不及物动词用了
on
这个介词
如果将这2句用which
来连在一起
on
the
book
便成为了
on
which
John
liked
the
book,
on
which
Mary
was
sitting.
(2)
的例子
John
has
a
book.
In
the
book
there
are
a
lot
of
pictures.
留意
in
the
book
连成2句的话
可得出
John
has
a
book
in
which
there
are
a
lot
of
pictures.
值得留意的是
由於这里的
which
都是跟在介词之後的
所以在原句中是’宾语‘
sitting
on
the
book
中的
book
是宾语
in
the
book
中的
book
也是宾语
至於whom
概念都是一样
用上
of
因为原句中出现了
of
这个介词
而
whom
也是宾语
不同之处
乃是
whom
指人
which
指非人的生物或物件
例子
There
are
ten
students.
Many
of
them
are
hardworking.
留意
many
of
them
many
是主语
of
them
中的
them
是介词
of
的宾语
连成一句
得出
There
are
ten
students,
many
of
whom
are
hardworking.
再看以下的2句
John
stared
at
the
girl.
He
was
fond
of
the
girl.
留意
fond
of
the
girl.
连成一句
得出
John
stared
at
the
girl,
of
whom
he
was
fond.
for
which
=
why
?吗
其实for
有
because
之意
单以
for
which
来解理
其中一个可能的解释是‘为了这/它...'
这也许可以理解为
why
吧
如果能提供具体的句子
也许能够给点意见

定语从句的of which in which on which怎么用主要是看后面状语的搭配

比如， i
live
in
guangdong,in
which(=where)
crops
grow
here.

这里后面的意思应该是， crops
grow
in
guangdong
,所以用in（地点）

i
caught
the
bus
,on
which
i
met
my
teacher.

这里后面的意思应该是i
met
my
teacher
on
the
bus,所以用on（地点）

i
like
,by
which
i
improve
my
english

这里应该是
i
improve
my
english
by
reading
english.所以用by（方式）

i
like
skiing,from
which
i
can
get
a
lot
of
happiness.

这里是
i
can
get
a
lot
of
happiness
from
skiing 。所以用from

做这种题，你先看看后面那个从句里要搭配什么样的介词，做熟了就容易了。

定语从句of which,in which用法这里使用的是that.
that和which都可以引导定语从句，同时，都可以在定语从句中担当主语或宾语。
一、that可以修饰人/物；which只能修饰物。
引导词作为主语的时候，和被修饰的先行词保持一致。引导词作为宾语时，可以省略。
如：
（1）the
boy
who/that
i
talked
with
just
now
is
my
best
friend.(the
boy在这里是先行词，后面的who/that
i
talked
with
just
now是定语从句。who/that在这里=the
boy ，在从句中作主语。
（2）the
book
(that/which)i
am
reading
is
very
interesting.(定语从句：(that/which)i
am
reading
；修饰的先行词是the
book.因为book是物品，因此that/which（=the
book)都可以，而book在从句中是被阅读的，作为从句中的宾语。可以省略。）
二、特殊情况
（1）只用that,不使用which
如：先行词前有序数词、最高级、the
only等词语修饰；先行词既有物又有人...
（2）只用which,不用that
引导词前有介词时，只能用which

定语从句。which .in which. on which . of which分别怎么用。？最这些都是定语从句里面，由which引导的定语从句，介词提前。
in which可以翻译成在„„里面 of which可以翻译成……的
on which可以翻译成在„„的上面，或具体时间的某一天

这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。
例如：
(1) The school (that/which) he once studied in is very famous. = The school in which he once studied is very famous.
(2) I have a dresser in my bedroom, which there are many cosmetics on. = I have a dresser in my bedroom on which there are many cosmetics.
（3）The house the roof of which was damaged has now been repaired. 那幢屋顶被损坏的房子现在已经修好了。
