定语从句中‘介词+which’的用法

关系副词 转变成 ‘介词+which’ 的形式..

怎样判断用什么介词呢？

which 引导定语从句，当定语从句中的which是做介词的宾语，就要在which前加介词。

1、表示地点，时间和原因的“介词＋which”分别相当于 where，when，why。

2、of ＋which”起形容词的作用，相当于whose（用来指物），其词序通常是“n. ＋of which”。

限制性关系从句

从语义上看，限制性关系从句主要起限定作用，修饰特定的人或事物，如果去掉限制性定语从句，整个句子表意会不完整甚至不通顺；从结构上看，限制性关系从句常紧跟先行词，并且同先行词之间一般不加逗号分隔（但不是绝对的）。

、"介词+关系代词"引导的定语从句

关系代词whom, which在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间;当先行词指人时,介词后的关系代词用whom, 其余用which,这时的关系代词不能省略;有时为了使关系代词紧跟它所修饰的先行词,也可以把介词放在从句中有关动词的后面,这时的which可用that替换。当介词放在从句有关动词的后面时,关系代词which, that, whom在口语中和非正式文体中经常省略。如:

This is the room in which he used to live. = This is the room (which / that) he used to live in. 这是他过去居住过的房间。

Who's the man with whom you just shook hands? =Who's the man (that / whom) you just shook hands with? 刚才你与他握手的那个人是谁?

但含有介词的短语动词一般不拆开,介词仍放在动词的后面。如:

This is the book (which / that) I'm looking for. 这就是我在找的那本书。

在这类定语从句中,介词的选择一般根据动词的需要,如上述几例,或者根据先行词来决定。如:

There is a mountain of which the top is always covered with snow. 有一座山顶总是覆盖着雪的山。

本回答被提问者和网友采纳 参考技术B 关于“介词 + which / whom”引导的定语从句
“介词+关系代词”引导的定语从句，是定语从句一种介词前置的定语从句句型，介词与关系代词之间存在一种介宾关系。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。
2.在限制性定语从句中，当介词置于定语从句的谓语动词之后时，可用that/which(指物)；that/who/whom（指人）作介词的宾语.且此处关系代词可以省略，特别是在口语中。如：
（1) The man (who/whom /that )you spoke to is a teacher.
（2）The city（which/that）she lives in is far away.
注：通常介词放在定语从句中动词后，也可以放在关系代词前面，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。关系副词实际上是介词＋先行词。其中
when=表时间的介词（如：in，at,during等）+which；
Where=表地点的介词（如：in，at,on,under等）+which；
Why=表原因的介词（如：for）+which
(1)当先行词表示时间，定语从句中缺少时间状语时，通常用关系副词when引导，此时也可选用表示时间的介词＋which来代替关系副词when。
I still remember the day when I came here. ( on the day =when)
(2)当先行词表示地点，定语从句中缺少地点状语时，通常用关系副词where引导，此时也可选用表示地点的介词＋which来代替关系副词where。
This is the house where I lived last year. ( in the house= where)
(3)当先行词为reason，定语从句中缺少表示原因状语时，通常用关系副词why引导，此时也可以用for which来代替关系副词why。
There are many reasons why people like traveling. (for the reasons =why)

三、关系代词前介词选择三原则：一先，二动，三意义（重中之重）

1.一先，即根据定语从句中介词与先行词的搭配关系选择。
I never forget the day on which I came to this school. (on the day)
2.二动，即根据定语从句中谓语动词与介词的搭配关系选择。
This is the iPad on which I spent 3000 yuan. (spend money on sth.)
3.三意义，即根据定语从句的意义来确定介词。
This is my pair of glasses, __without which__I cannot see clearly.
例题：用“介词+关系代词”的形式表示
1. Do you like the book __________ she learned a lot?
2. He paid the boy $10 for washing ten windows, most ______ hadn't been cleaned for at least a year.
3. The tower _________ people can have a good view is on the hill.
注意：
介词+关系代词
1）介词后面的关系代词不能省略。
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,where和why互换。 参考技术C 你得根据谓语动词的用法来用。。。或者看句子成分是否完整来用..其实介词+which相当
于一个状语。有实际问题可以来追问我。我帮你。 参考技术D 去掉which把这句话按照正确的语序读出来试试
如：Frank's
dream
was
to
have
his
own
shop(
)to
produce
the
workings
of
his
own
hands.
这里填in
which为什么呢？
就把他的正确语序读出来看看啊
Frank's
dream
was
to
produce
the
wokings
of
his
own
hands
__in__
his
own
shop.这里which指代的就是先行词shop
这种介词+which的用法大多都是定语从句中碰到的吧，你多做一些题目，自然而然就会理解了~
