介词加关系代词引导的定语从句
定语从句是由关系代词或关系副词引导的从句，用于修饰先行词，在句中作定语。

当关系代词在定语从句中作介词宾语时，我们通常用“介词+关系代词”引导定语从句。

以下是关于介词加关系代词引导的定语从句的详细介绍：
- 如果指“人”，用“介词+whom”。

如：I’ll never forget the time during which I spent my childhood in the country. 我永远不会忘记孩童时代我在乡村度过的时光。

- 如果指“物”，用“介词+which”。

如：The little girl is reading a book in which there are many pictures. 那个小女孩正在读一本书，书中有很多图画。

确定介词时，可以从以下三方面入手：
- 先行词的意义；
- 从句中的动词或形容词与先行词的固定搭配；
- 句子的意思。

在使用“介词+关系代词”引导定语从句时，需要注意不同介词的用法和含义，以确保句子的准确性和流畅性。

“介词+ which / whom”引导的定语从句“介词+关系代词”引导的定语从句，介词与关系代词之间存有一种介宾关系。

当关系代词在定语从句中作介词宾语时，把介词置于关系代词前，即演变出“介词+关系代词”句型。

例如：The man who/whom /that you spoke to is a teacher.=The man to whom you spoke is a teacher.一、基本构成1.“介词+关系代词”结构引导的定语从句中，关系代词只能用which（指物）或whom(指人) ，即：介词+which/whom。

（1）The man to whom you spoke is a teacher.（2）The city in which she lives is far away.（3）The little girl is reading a book,in which there are many cartoons.注意：当介词放在关系代词的前面时，用在介词后的关系代词不能省略。

注：通常介词放在定语从句中动词后，也能够放在关系代词前面，但有些特殊动词短语搭配不能拆分，介词只能放在动词后，如：look for, look after, pay attention to ,take care of , look forward to, listen to等。

This is the pen that / which you are looking for.The patient whom she is looking after is her father.The words that /which we should pay attention to are written on the blackboard. There are fifty patients who/whom/that we must take good care of.二、关系副词when，where，why可用“介词＋which”来代替。

定语从句中只能用which
定语从句中只能用which，不能用that的几种情况：
1. 在介词后面的关系代词用which而不能用that。

即“介词+which（代物）”例如：
The picture for which he paid $1,000 was once owned by a duke.
他花了1000美元买下的画曾为一名公爵所拥有。

The building in which Han Mei studied was very old.
韩梅在里边学习的那幢大楼很旧。

2. 在非限定性定语从句中不能用that。

例如：
Crusoe's dog, which was very old now, became ill and died.
克鲁索的狗，现在已经很老了，病死了。

3. 有两个定语从句，其中一个关系代词已有which，另一个宜用that。

相反，如果其中一个为that，另一个宜用which。

Edison built up a factory which produced things that had never been seen before.
爱迪生办了一个工厂，生产过去从未见过的东西。

Let me show you the novel that I borrowed from the library which was newly open to us.
让我给你看看我从新开放的图书馆借来的小说。

定语从句中关系代词只能用which 引诱的几种情形
(1) 当关系词前面有介词时,指物经常应用which.
The prize for which he worked so hard was a ne w bike.
He built a telescope through which he could stud y the skies.
(2) 非限制性定语从句指物时,多用which.
Bamboo is hollow,
which makes it light.
He wrote an article, which tells us about the c omputer.
(3) 假如先行词本身是that时,只用which.
This is that which he bought yesterday.
(4) which还有一种特别用法,它可以引诱从句润饰前面的全部主句,代替主句所暗示的整体概念或部分概念.在这种从句中,which可以作主语,也可以作宾语或表语,多半情形下意思是与and this 类似,例如：
He succeeded in the competition, which mad e his parents very happy.。

定语从句which的例子定语从句which的例子which可以指代地点也可以是时间,下面要为大家分享的就是定语从句which的例子，希望你会喜欢！inwhich的用法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=wherein which 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 lived in the house in which Tom once lived.He lived in the house where Tom once lived.定语从句中.如this is the room in which we 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 room which we stayed in.这里的介词是可以提到which 前的定语从句in_which等的.用法in which, for which, on which, 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。

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。

“介词＋ｗｈｉｃｈ／ｗｈｏｍ”引导的定语从句“介词 +关系代词”既能引导限制性定语从句又能引导非限制性定语从句。

先行词是指物的名词时关系代词用which；先行词是指人的名词时关系代词用whom。

此结构注意以下几点：1．“介词 +which”在定语从句中分别作时间、地点、原因状语，代替相应关系副词。

There used to be a time at which/during which/when the Chinese people struggled for freedom.中国人民曾有一段为自由而斗争的日子。

The factory in which/when my father works is a large one. 我父亲工作的那家工厂很大。

I would like you to explain the reason forwhich/why you were absent.我想让你解释一下你没来的原因。

2．在一些固定搭配的短语动词中，由于动词和介词不可分割，因此不能把介词置于关系代词之前。

This is the pen which I’m looking for.这是我正在找的那支钢笔。

不可以说：This is the pen for which I’m looking.常见的不可拆开的动词短语有：care for关心，喜欢；deal with处理，对付；hear from收到某人的信；look for寻找；look after照顾；send for 派人去请；see to照顾，料理。

3．“名词+ of which”代替“whose +名词”在定语从句中作定语。

The book, the cover of which/of which thecover/whose cover is black belongs to me.那本封面是黑色的书是我的。

I saw some trees, the leaves of which/whoseleaves/of which the leaves were black with diseases. 我看见一些树，它们的叶子因得病而发黑。

定语从句which例句定语从句which例句定语从句which例句如下：1、指物定语句做主语或者宾语做宾语省略(1) Football is a game which is liked by most boys.(2) This is the pen (which) he bought yesterday.2、关系代词定语句做介词宾语句由介词+关系代词引导(1) The school (that/which) he once studied in is very famous.(2) The school in which he once studied is very famous.(3) Tomorrow I will bring here a magazine (that/which) you asked for.(4) Tomorrow I will bring here a magazine for which you asked.(5) We'll go to hear the famous singer (whom/that/who) we have often talked about.(6) We'll go to hear the famous singer about whom we have often talked.定语从句之which和asas和which都可以引导非限制性定语从句，先行词为整个主句或主句中的一部分内容，先行词在定语从句中作主语、宾语或表语，as 与which均不可省略，有时两者可以互换。

例：He married her, as/which was natural.他跟她结婚了，这是很自然的`事。

只用as而不用which：一、当定语从句置于主句前面时：例：As you see, the Chinese people are hard-working. (定语从句在句首)你知道，中国人民是勤劳的。

介词+which/whom结构的用法□安徽/王振祥在定语从句中，有时引导定语从句的既可以是where或when，也可以是介词＋which／whom。

其中，介词＋which／whom引导的定语从句的现象常令同学们无所适从，不知道该用哪个介词。

那么，介词从何而来呢？下面我们就此问题分析讲解一下。

一、当先行词在定语从句中充当介词宾语时，可使用介词＋which／whom的结构引导从句。

指物时，只能用which ；指人时，只能用whom 。

例如：She is the very girl with whom I went t o the conference last week.她就是我上周一同去开会的那个女孩。

He made a telescope through which he could observe the stars.他做了个望远镜，用其观察星座。

但是，若该介词与其前的动词是一固定词组，则通常不拆散该词组，该介词仍位于定语从句的句中或句末。

此时，指人时，可用who或whom ；指物时，可用which或that ，且多可省略。

例如：This is the girl ( who / whom ) they have taken good care of for over a year.这是他们已精心照料一年多的那个女孩。

（take care of 为固定词组，不可拆开）Skating is the sport ( which / that ) people go in for in winter.滑冰是人们冬季喜欢从事的运动。

（go in for 为固定词组，不可拆开）该结构既可引导限制性定语从句，也可引导非限制性定语从句。

例如：She is telling a story about Lei Lei, of whom ever one of our class is proud.她在讲述雷雷的故事，雷雷是我们全班同学都为之感到自豪的人。
