which,in which,on which,for which,by which的区别

这里where是副词作表语,而in which则应是名词作表语.
例,That's the city in which he grew up.
显然,若要用in which,则前面一般应有主体词
这里,the city还可以是place,villige,school 等

翻译出来你就知道为什么了 ：）
这句话的意识是说：他有一个本子是用来记他朋友的名字和地址的.
然后,既然是用来记录,肯定不是用来记录一个人,
他有很多朋友.
所以这种情况 一般来说 都用复数.

介词+关系代词=关系副词
in+which=where
句子拆分：
It is the school.
You learn English in the school every evening
显然介词用的是in ,which代替了the school
综上,选D

一般情况下
on which= when
for which=why
in which=where

in which 本章（节）中,
in which Sophie talks to hats
本集中索菲对帽子说
in which Sophie is compelled to seek her fortune
本集中索菲产生发财的梦想
in which Sophie discovers several strange things
本集中索菲发现几件怪事
...
the one with
...一集
the one after……
...之后一集
the one where...
在这一集中...
主要还是看后面接着要说什么而定前面具体用什么

1.in which是介词加关系代词,引导定语从句
in可以放到从句中去
our immune system breaks down in this condition
2.把in放进从句中应该是这样的：
it is transmitted from one person to another in the way.
不是都能组成动词短语的,你得了解介词加关系代词引导定语从句时,介词如何去选择,不光是由从句动词去决定,还可能是由先行词决定,等等.
（1）以从句中动词；形容词；名词与介词的固定搭配而定；
[高考考例]2.In the dark street,there wasn’t a single person _____ she could turn for help.[MET 1992]
A.that B.who C.from whom D.to whom
[思路点拨]答案为D.turn to sb for help 为固定搭配表示“求助于某人”
（2）以先行词与从句中的动词关系及所表达的含义而定或以先行词在定语从句中的作用与含义而定.
[考例]1.The medicine of science,______ progress has been very rapid lately,is perhaps the most important of all the science.
A.to which B.in which C.which D.with which
[思路点拨]答案为B.从句主谓结构搭配为：progress has been rapid in,这里的in意为“在某方面”,相当于rapid progress has been made in the science of medicine.
[考例]2.The professor made his first speech _____ he talked about some subjects the students were interested.
A.that B.which C.in which D.of which
[小结]关键词：介词的选用与从句主谓结构的搭配有关.

当way做先行词,并在定语从句中做状语时,关系词用that或in which或省略
先行词是the way时,其后的定语从句关系词有三种,例如：
I like the way in which / (that) the teacher gives his lessons.
从句缺少的是主语、宾语还是状语是确定用关系代词还是关系副词的关键.也就是说要看先行词在定语从句中担任什么成分
试比较：
I will never forget the day (which/that) I spent in Hongkong.
( spent是及物动词,后缺宾语,因此用关系代词或省略 )
I will never forget the day when/on which Hongkong returned to its motherland.
（ 从句主谓宾结构完整,缺状语,因此用关系副词或介词加关系代词 ）
The reason （that/which）he gave for not coming to school yesterday is unbelievable.
( gave是及物动词,后缺宾语,因此用关系代词或省略 )
The reason why he didn’t come to school yesterday is unbelievable.
（ 从句主谓宾结构完整,缺状语,因此用关系副词或介词加关系代词 ）

这里说的“the way/day + 从句”涉及到了表示一些方式、时间、处所的名词在前面加了the, each, every, some, one 以及其他数词等限定词后转化为副词性的问题. 一、“限定词+名词”作状语是一种常见的语法现象,但是仅限于表示时间、距离、方式、处所以及各种度量等概念的名词.例如： 　　1、表示时间　　 Wait a moment. 稍候　　 My brother called me from Shanghai last night.我的兄弟昨晚从上海打电话给我.　　2、表示距离　　 I couldn’t move a step further. 我连一步也走不动了.　　 John can walk five miles an hour.约翰一小时能步行五英里.　　3、表示方式　　 You can do it this way.你可以这样做.　　 All the other way, he won’t agree with you.完全相反,他不会同意你的.　　 Come this way, please.请这边走.　　4、表示度量　　 This box weighs five kilogram’s.这只箱子重五公斤.　　 The room measures five metres across.这房间有五米宽. 二、这类结构还可以整体出现在宾语的位置上,例如你所举的例子： I don't like the way you speak to your mother. （方式状语从句）Thousands of foreigners were attracted to the Shanghai World Expo the day it opened.（时间状语从句） 三、关于此类句子的属性 　1、“限定词 + 名词”用作复合连词,引导的是宾语从句.如：　　I won'ttalk to him (the way my father did). ——直接宾语 2、“限定词 + 方式名词”作宾语,后面的从句用以说明该抽象名词具体所指,因此是省略 that 的同位语从句.如：　　They didn't do it the way (that we do now). 3、“限定词 + 名词”作宾语,后面的从句是省略关系词 when、where 或 in which的定语从句.如：　　I won't talk to him the way (in which my father did).　　Thousandsof foreigners were attracted to the Shanghai World Expo the day (when it opened).　　This is the place (where I used to visit) 事实上,后两种说法只是理论上的分析,实践中很少使用. 四、除此之外,这类结构还可能引导状语从句,如： 　　Each place you come, you will be well entertained. 每到一地,你都会受到款待.　　Themoment I saw you, I knew you were angry with me. 我一看到你, 就知道你在生我的气.

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

C
in 为从句中 修饰Chinese astronauts 和 which指代的manned spaceship 之间关系的必要介词
Chinese astronauts 不能 at,也不能 by ,更不能 from --manned spaceship
所以C

【that】可引导宾语从句、表语从句、主语从句等,但是不可以引导状语从句,常用的状语从句有条件状语从句（通常由if、whether引导）,和时间状语从句（通常由when引导）
【in which】是引导定语从句的,只不过它是后面从句的状语而已.

美国人欢迎人的方式.
看到了吗?方式way在定语从句中作介词in的宾语,其实就是介宾短语in the way,所以做宾语当然可省了,呵呵

you said you want to--> wanted to
young girls at your age hopes --> hope
beaautiful --> beautiful
do not let others' ideas to affrct your normal life --> do not let others' ideas affect your normal life
it is good idea to do it --> it is A good idea to do it
by taking more will help you on your studies and help us get over difficulties on DIETING (这句看不懂,是不是漏字了?读不通.)

你这个问题要概括起来,大约能用A4纸打印10页,你觉得可能有人愿意这么做么?你可以百度一下各个关键词,或者到书店买相应的语法书.英语没有捷径,积累和努力是关键.

逗号没问题.这里其实where和in which没神马区别.可以替换.但我会用in which.因为你前面说的news和world report都不是地方.where一般强调地点咯.实际没神马区别.
^^^^^^^^^^^
偷来的答案：
Where和in which用法一样,都可以引导地点状语.这两个词的一点区别是,In which 可以引导非限制性从句,In which 前面要用逗号隔开,表示从句只是附加说明,有没有都行.这里前后没用“,”那就该选where.

1-----------X=W+Y+Z
2-----------2 W=Y+1
3-----------3 Z=W-5
利用2和3式,将y和z化为w,得：
x=w+2w-1+1/3w-3/5w
化简：3x=10w-8
然后从x=1开始代入
因为题目说是整数,所以在代到x=4时就行
所以x=4 w=2 y=3 z=-1

that和which在定语从句中作宾语,一般后面是及物动词
如
This is a book thatwhich I like very much.(like 是及物动词）
in which 一般后面是不及物动词,和in 搭配,把in 提前
如
This is the place in which I will stay.

where可以用在定语从句和状语从句中.
in which可以用在定语从句中,但是如果所修饰的名词前面已经有了介词了,则最好考虑用where.
There is an apple in the box,____ you can also find some oranges.在这里,最好考虑选择用where,因为所修饰的名词box前面有介词了

(1) The reason __for___ __which___he refused the invitation is not clear,
(2) From the year ___in___ __which___ he was going to school he began to know me.
(3) Great changes have taken place in the city __in___ ___which__ I was born.

第一个in which的 which是指代oyster,因为珍珠在oyster生成.
后面的which是指代water的.

that 和which在定语从句中作引导词,既可指人也可指物.一般可以通用.Can you remember the story that/which I told you last week? 它们的区别主要体现在：
1.在有‘选择性’时,用which. There were so many books on the shelves. I really couldn't find the book which Mr Wang wanted to give me.书架上有那么多书.我确实找不出王先生要给我的那本.
2.主句中有who,the only one 等词时,用that,不用which. Who was the man that went with you?跟你一起去的人是谁? This is the only thing that I like.这是我唯一喜欢的东西.
3.如果引导词前有in,at等介词时,用which,不用that. This is the house in which my parents used to live.这是我父母过去常住的房子.

1 关系代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分.关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致.
1）who, whom, that
这些词代替的先行词是人的名词或代词,在从句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想见的人吗?（who/that在从句中作主语）
He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人.（whom/that在从句中作宾语）
2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换）, 例如：
They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙.
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书.
3）which, that
它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语等,例如：
A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣.（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了.(which / that在句中作宾语）
----------------------------------------------------------
2 关系副词引导的定语从句
关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语.
1）when, where, why
关系副词when, where, why的含义相当于"介词+ which"结构,因此常常和"介词+ which"结构交替使用,例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候.
Beijing is the place where (in which) I was born. 北京是我的出生地.
Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗?
2）that代替关系副词
that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句,在口语中that常被省略,例如：
His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了.
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方.
------------------------------------------------------
3 判断关系代词与关系副词

方法一： 用关系代词,还是关系副词完全取决于从句中的谓语动词.及物动词后面无宾语,就必须要求用关系代词；而不及物动词则要求用关系副词.例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判断改错（注：先显示题,再显示答案,横线；用不同的颜色表示出.）
（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.
习惯上总把表地点或时间的名词与关系副词 where, when联系在一起.此两题错在关系词的误用上.
方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状),也能正确选择出关系代词/关系副词.
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D,例2 A
例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This is the museum ___ the exhibition was held.
在句1中,所缺部分为宾语,而where, that, on which都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D.
而句2中, 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语.而此题中,介词on 用的不对,所以选A.
关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时,选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时,应选择关系副词 ( where 地点状语,when 时间状语,why 原因状语) .
---------------------------------------------
4 限制性和非限制性定语从句

1) 定语从句有限制性和非限制性两种.限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开,例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子.（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的.（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了,他曾经是我的老师.
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园.
This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍.
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数,例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦.
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发.
说明：关系代词that和关系副词why不能引导非限制性定语从句.

-----------------------------------------
5 介词+关系词

1）介词后面的关系词不能省略.
2）that前不能有介词.
3） 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换.
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
----------------------------
最后给你说下that的用法：

1）不用that的情况
a) 在引导非限定性定语从句时.
(错) The tree, that is four hundred years old, is very famous here.
b) 介词后不能用.
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.
2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中,只用that,不用which.
b) 在不定代词,如：anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which.
c) 先行词有the only, the very修饰时,只用that.
d) 先行词为序数词、数词、形容词最高级时,只用that..
e) 先行词既有人,又有物时.
举例：
All that is needed is a supply of oil.
所需的只是供油问题.
Finally, the thief handed everything that he had stolen to the police.
那贼最终把偷的全部东西交给了警察.

如果the way后面是引导定语从句,如果way在这个定语从句中是做宾语,就用which/ that/不填,
若是做状语,就用in which/ that/不填.

D

没有in where的用法吧!
where可以直接引导表示地点的从句,例如：
It's a place in which/where he visited before.
而in which在一起使用的时候,相当于where,引导表示地点的定语从句：见上例.

你可以把句子改一下,变成Which is this the place your father once lived in?这就证明是可以用 in which的

定语从句中where=in which/at which/on which等
另外你这句不是定语从句,缺少先行词,你这里只能选A
如果要选in which 则句子应是the famous scientist grew up in the town in which he was born...

去掉"you said in your letter",句子结构容易看清楚.顺便说一下,最后一个单词pursue是动词,用在这里是错误的,应该改成名词或动名词:pursual或pursuing.参考下面的句子：
Is this the village ___ your grandpa was once hidden from the enemy's pursuing?
在正式的英语中,in which是非限定性定语从句,要和主句隔开,where是限定性定语从句,不用隔开.
所以：
Is this the village where your grandpa was once hidden from the enemy's pursuing?
=Is this the village,in which your grandpa was once hidden from the enemy's pursuing?
所以答案选B.

不矛盾.the way 的用法比较特殊,到底具体怎么用法就要看后面从句中way 所替代的部分在从句中期的作用了,如果就是某种方法往往是做状语的,如果是行为举止,往往做主语

首先,你所列举的这些一般都出现在which引导的定语从句中.
for which一般表示原因
in which一般表示地点或方位等
of which,with which,to which这些要看后面从句中不及物动词的具体意思而定
不是不及物动词的后面没加介词,而是把这些介词提前了,提到了which的前面
因为英语的习惯是先表明要表达的意思,有时候句子很长,所以把介词提前,避免头重脚轻,也可以先提示读者后面的意思

在这个句子当中 in which 组合做的是状语 ,你看,the house在从句中做的就是状语成分,所以in which 做的是状语
但是in which组合不一定就是做状语 也有可能因为从句中的动词是不及物动词 所以后面要跟介词（或者表达那个意思的时候 后面跟一个固定搭配的介词 ）这个时候 which就是做介词的宾语

that是引导连词．用于主语／宾语／表语／同位语从句中．
which是连接代词．用于主语／宾语／表语从句中．
in which比较复杂．它有时＝where／when这个得有具体的句子才好分析．你最好问问例题!

in是介词,后面只能跟which,所以没有in that1

宾补就是宾语补足语,用来进一步说明宾语 如：we call her( Lucy) .lucy 是对her的补充说明,她就叫lucy.
宾语从句是指 从句 在句子中充当宾语的部分,如：tell sb sth 这是一个词组,sb / sth 都充当了宾语的成分,就是所谓的双宾语.如果我用一句话来代替sth 的位置,这句话就是从句,就是所说的宾语从句.例：she tells us (that her father is a teacher.) 括号里是sth 的成分,但是是个句子,叫做宾语从句.
在宾语从句中,that 不做任何成分,可以省略.只做连接的作用,读起来通顺一点,就像我上面举例的一样
what 在宾语从句充当成分,有具体意思,可以解释成什么东西或什么人.

前提是在定语从句中,关键要讨论先行词是时间还是地点.但是有些引导词是不能替换的：例如：by which,from which----因为这些介词本身就有意义了,就不能像when、where这样只替代先行词的意义了.
能替代的,可以互换的往往是前几个常见的：例如--at which = when、where

Lilies of the Field 学会欣赏身边的景色
读好书是欣赏,听音乐是欣赏,看优秀的电视节目是欣赏,走出家门去领略大自然的美好景色同样是欣赏,生活中到处都有可供欣赏的客体.学会欣赏,它会让你的生活更有诗意,让你在获得精神享受的同时,进而获得心身的健康.

You will walk out of here this afternoon with only one thing that no one else has. There will be hundreds of people out there with your same degree; there will be thousands of people doing what you want to do for a living. But you will be the only person alive who has sole custody[1] of your life.
Your particular life. Your entire life. Not just your life at a desk, or your life on a bus, or in a car, or at the computer. Not just the life of your mind, but the life of your heart. Not just your bank account but your soul.
People don’t talk about the soul very much anymore. It’s so much easier to write a resume[2] than to craft a spirit. But a resume is a cold comfort on a winter night, or when you’re sad, or broke, or lonely, or when you’ve gotten back the test results and they’re not so good.
Here is my resume:
I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent. I no longer consider myself the center of the universe. I show up. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today, because I would be a cardboard cutout[3]. But I call them on the phone, and I meet them for lunch.
I would be rotten, or at best mediocre[4] at my job, if those other things were not true. You cannot be really first rate at your work if your work is all you are.
So here’s what I wanted to tell you today: Get a life, a real life, not a manic[5] pursuit of the next promotion, the bigger paycheck, the larger house.
Do you think you’d care so very much about those things if you blew an aneurysm[6] one afternoon, or found a lump in your breast?
Get a life in which you notice the smell of salt water pushing itself on a breeze over Seaside Heights, a life in which you stop and watch how a red tailed hawk circles over the water or the way a baby scowls[7] with concentration when she tries to pick up a toy with her thumb and first finger.
Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure, it is work. Each time you look at your diploma, remember that you are still a student, still learning how to best treasure your connection to others. Pick up the phone. Send an e-mail. Write a letter.
Get a life in which you are generous. Look around at the azaleas[8] in the suburban neighborhood where you grew up; look at a full moon hanging silver in a black, black sky on a cold night. And realize that life is the best thing ever, and that you have no business taking it for granted.
Care so deeply about its goodness that you want to spread it around. Take money you would have spent on beers and give it to charity. Work in a soup kitchen[9]. Be a big brother or sister.
It is so easy to waste our lives, our days, our hours, our minutes. It is so easy to take for granted the color of the azaleas, the color of our kids’ eyes, the way the melody in a symphony rises and falls and disappears and rises again. It is so easy to exist instead of to live.
I learned to live many years ago. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and utterly. And I tried to do that, in part, by telling others what I had learned. By telling them this: Consider the lilies of the field. Look at the fuzz[10] on a baby’s ear. Learn to be happy.
Look at the view. You’ll never be disappointed.

今天你走出这里时,你只有一件与众不同的东西.说到学位,有成千上万的人的学位跟你的一样高；说到职业,有成千上万的人正在做你毕业后想从事的工作.可是,你是活着的人当中惟一能够掌管自己生命的人.
你的生命是独一无二的.你的整个生命,并不只是在课桌前,也不只是在公共汽车上、小汽车里、电脑前.不只是你的思想的生命,而且还是你的心灵的生命.不只是你的银行帐号,而且还有你的灵魂.
现在谈灵魂的人少了.写一份简历容易,画一个灵魂却难得多.可是一份简历只是在寒夜里,在你难过时、破产时、孤独时、考试成绩不如意时的一份冷冷的安慰.
以下是我的简历：
“我是三个孩子的好母亲,我尽力不让我的职业妨碍我做一个好母亲.我不再把自己看作宇宙的中心.我跟孩子们在一起,倾听他们说话,与他们一起欢笑.我是丈夫的好朋友.我努力信守我们结婚时的承诺.我是我的朋友们的好朋友,他们也是我的好朋友.没有他们,我今天就不知道对你们说些什么,因为没有他们我会是一个平淡无奇的人.我给他们打电话,和他们共进午餐.
如果上述的一切不是真实的,我的工作会单调乏味,我的一辈子会碌碌无为.如果工作是你的一切,你绝对不可能把你的工作做到最好.”
这就是今天我要告诉你的：去生活,真正地去生活,而不是疯狂去追求升职,去追求加薪、买大房子.想想,如果有一天下午你突然被诊断出患了动脉瘤或乳腺癌,你还那么在乎名和利么?
去品尝海风的咸味吧,去观看盘旋的雄鹰吧,去留意孩子努力用大拇指和食指抓起玩具时的专注吧.
不要孤独地过日子,找一个你爱的人和爱你的人.记住爱不是休闲,而是工作.每次你看着你的文凭,要记得你仍然是个学生,仍然在学习怎样好好珍惜你和别人的联系.拿起电话,发一个e-mail,写一封信.
过慷慨的生活.到郊外去观赏盛开的杜鹃花吧,在寒夜里看挂在空中的那轮银色的月亮吧.要意识到生活从来都没有这么美好过,不要把生活和你所爱的人视为理所当然.
多关注生活中的善,并把它向你的周围传播.把你用来喝啤酒的钱捐给慈善事业,去做义工.
时间一天一天地过去,一分一秒地流逝,浪费我们的生命很容易.我们对火红的杜鹃视若无睹,对我们孩子眼睛的颜色视若无睹,对优美的旋律置若罔闻.我们懂得生存,却不会生活.
许多年前我就学会了生活.我学会了去看世上所有美好的事情,并努力地给她增添美好.我尽量这样做,在某种程度上,我也告诉人们我的发现,叫他们也想想野地里的百合,看看婴儿耳朵里的绒毛.学会保持快乐!
学会欣赏身边的景色,你就永远也不会失望.

在定语从句中 ,先行词表地点where和in which可互换,where还可引导其他从句,in which知只能用在定语从句中

定语从句,先行词“day”在从句中作宾语
I'll never forget “the day”用which
which指代物,一个物品 最为常用.
in/on which=where 视具体地点而定、可以翻译成在……里面、
在……的上面for which=why 表示原因、可以翻译成为了……目的
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.

没有on that这个that 之前不能接介词,on which、in which是当定于从句中动词分别接介词on 、in时加
