inwhich定语从句
in which定语从句
in which中的which是指代前面的东西,which可以指代地点也可以是时间,也就是说前面的先行词只要是可以和in搭配的就可以,in which的用法有哪些呢?本文是店铺整理in which的用法的资料，仅供参考。
in which的用法
which用于定语从句，作关系代词，在句中要做成分
inwhich用于定语从句，作关系副词，在句中不做成分，inwhich=where
inwhich只搜索能用在定语从句中，等于where,在定语从句中作状语。
如：He livedinthe houseinwhichTom once lived.
He livedinthe house where Tom once lived.
定语从句中.如
this is the roominwhichwe stayed
先行词是room，后的句子是用来修饰room的
但是room不可做stay的成分，因为stay是不及物动词，后不可直接家宾语，所以要有个介词.
其实上述的句子
this is the roomwhichwe stayedin.
这里的介词是可以提到which前的
定语从句in which等的用法
inwhich, forwhich, onwhich, atwhich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。
inwhich可以翻译成在……里面
forwhich可以翻译成为了……目的
onwhich可以翻译成在……的上面，或具体时间的某一天
atwhich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 studiedinis very famous.
= The schoolinwhichhe 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 forwhichyou asked.
(3) I have a dresserinmy bedroom,whichthere are many cosmetics on.
= I have a dresserinmy bedroom onwhichthere are many cosmetics.
(4)The dumpling Housewhichhe often has dumplings at is very popular.
= The dumpling House is very popular, atwhichhe 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,inwhichcase there’s no pointinour waiting. (固定搭配：inthe case)
The speaker paused to examine his notes, atwhichpoint a loud crash was heard. (固定搭配：at the point)
Ten years of hard work changed her greatly, forwhichreason he could hardly recognize her at first sight.(固定搭配：for the reason)
The film atwhichI fell asleep was very boring.
(Here "atwhich" is based on "fell asleep at the film"因为电影无聊而睡觉。) The little creatureinwhichscientists are interested is known as ET.
(这里"be interestedin"是词组原因)
This is the book forwhichhe is looking.
(即等于This is the bookwhichhe 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. where B. atwhichC. aboutwhich限制性从句
【解答】选B。这个是非限制性定语从句，atwhich在功能上等于where，但就本题而言只能选atwhich。因为atwhichI 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atwhich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 returninnear future.
A. onwhichB. bywhichC. towhichD. fromwhich
【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 powerinnear 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. withwhichB.inwhichC. forwhichD. ofwhich
【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/forwhichhe did it.
The reason why/forwhichhe was fired was not clear.
There are many countriesinAsia, ofwhichChina is the largest one.
亚洲有很多国家，中国是最大的一个。
附：whose和 ofwhich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;ofwhich只能指物，有时whose可以与of whom和ofwhich互换使用。如：
The girl whose hair is golden is from England. 头发金的那个女孩是英国人。
The house whose doors(ofwhichthe doors) are green is an office building. 门是绿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ofwhich。
(1)定语从句的主语是few, little, some, most, many, much等时，一般只用of whom和ofwhich。
Inthe 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 ofwhichI 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ofwhich。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ofwhich。如：
