定语从句which的用法是什么
定语从句which的用法是什么定语从句which的用法是什么导语：定语从句which的用法有哪些呢?以下是店铺为大家整理的文章，欢迎阅读!希望对大家有所帮助!定语从句which的用法which是定语从句的关系代词之一。
GMAT语法考试限定，which 有且仅有两种用法。
一，which前面有逗号，逗号前面是个名词，which就近指代那个名词。
(1) Tankfield emailed Pea some photos, which did not cheer Pea up.which就近指代photos，定语从句中谓语动词did not cheer (Pea up)的发出者即从句主语即先行词photos，是photos没让豌豆家属高兴起来。
(2) Tankfield emailed Pea some photos, which Pea did not find interesting.which就近指代photos，photos是定语从句中的宾语，把定语从句还原成一个完整句就是Pea did not find the photos interesting.可以看到，上面两个句子都可以以that为关系代词改写，即(1)’ Tankfield emailed Pea some photos that did not cheer Pea up.(2)’ Tankfield emailed Pea some photos that Pea did not find interesting.改写与原版区别在哪儿?就在一个逗号。
which前面是名词，名词和which之间没逗号的，在GMAT语法里算错。
二，which前面是介词，介词前面是名词，which就近指代介词前的那个名词，名词和介词之间有无逗号均可。
Tankfield once lent Pea a book from which Pea glimpsed the basics of genes.这个句子可以“拆”成如下两句：(每个定语从句都可以拆成两句，以先行词为拆分点)Tankfield once lent Pea a book. Pea glimpsed the basics of genes from the book.先行词实际上是定语从句中介词的宾语，这时，需要把介词提前，避免如下表达：Tankfield once lent Pea a book, which Pea glimpsed the basics of genes from. (XXX)Tankfield once lent Pea a book that Pea glimpsed the basics of genes from. (XXX)上中学的时候学过，which引导的定语从句叫“非限制性定语从句”，是不是?它怎么就“非限制性”了?回顾上述GMAT语法规定which有且仅有的两种用法，which指的都是就近的名词，从句其实还是限制性的。

The London team, which played so well last season, has done badly this season. 伦敦队上一个季度打得很好，这个季度却打得很差。
2. 直接放在介词后作宾语时，通常要用which：She may be late, in which case we ought to wait for her. 她可能晚到，那样我们就要等等她。
The documents for which they were searching have been recovered. 他们找寻的文件已找到了。
This morning some port wine came, for which I have to thank you. 今天早上送来一些波尔图葡萄酒，为此我得向你道谢。

which在非限定性定语从句的用法
which在非限定性定语从句的用法下面是小编整理的一些关于which在定语从句中的用法，希望对大家有帮助。
关系代词which的用法(1)在非限定性定语从句中，只宜用which, 不宜用that.(非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若将非限定性定语从句放在句子中间，起前后都需要用逗号隔开。
翻译成人类的语言就是：有逗号的句子…)例句：Beijing, which is the capital of China, is a very beautiful city.(2)在限定性定语(就是正常的句子)从句中which和that在指代物的时候常常可以通用，但是有时只宜用which而不用that 。
关系代词前面有介词的时候 (也就是说，有介词就不能用that) 例句：This is the hotel in which you will stay.(3)"介词+关系代词"引导的定语从句关系代词(基本上除了when, where, why, how以外都叫关系代词……)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。
含有介词的短语动词一般不拆开,介词仍放在动词的后面。
例句：his 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。
例如 This is the house in which my family lived during the war.这个句子中从句"which my family lived"中的动词是live,你不能说livehouse吧,只能说live in house,这里live和in搭配所以which前就要家in.(4)所以说你想要知道到底which前用不用加介词和加什么介词主要有两点:1是你要看这个从句缺不缺介词,2是要看动词与介词的固定搭配,这就是要背的了.例句：This is the girl which I like.这句就不缺介词,你可以把句子反过来看看通不通顺.反过来就是I like this girl.这个句子是对的,不缺成分,那么它也就不用加介词.This is the question about which I always think.这句就是think about 这个词组的搭配了.一般考试会出现的就是live in, think about, hold on 之类的了.只要你多练习把句子反过来就能够掌握了~。
which的三种用法
which的三种用法1. 作为疑问代词 We may use "which" as an interrogative pronoun to inquire about a specific choice or option. For example, "Which color do you prefer, blue or red?" or "Which movie should we watch tonight?" It helps to narrow down choices and seek specific information.2. 作为关系代词 In addition, "which" can function as a relative pronoun to introduce a relative clause and provide additional information about the noun it refers to. For instance, "The book, which is on the shelf, is my favorite." Here, "which" connects the relative clause "is on the shelf" to the noun "book" and gives more details.3. 作为限定性让步从属连词 "Which" can also act as a restrictive concessive subordinating conjunction. It implies a contrast or concession by introducing a subordinate clause. For example, "She made a mistake, which was forgivable considering the circumstances." In this case, "which" introduces the concessive clause "was forgivable considering the circumstances," which presents a contrasting viewpoint.这些是"which"的三种常见用法，可以根据语境和需要使用适当的用法。
作宾语指物能用which
作宾语指物能用which
是的，作为宾语指代物的情况下，可以使用"which"。
比如，
"I bought a new car, which is very fuel-efficient."（我买了
一辆新车，它非常省油。
）这里的"which"指代的是"car"。
在复杂
的句子结构中，"which"可以用来引导非限定性定语从句，用来对先
行词进行补充说明。
例如，"The book, which I borrowed from
the library, was very interesting."（我从图书馆借的那本书非
常有趣。
）这里的"which"引导的从句对"book"进行了进一步的说明。
总的来说，"which"在句子中作为宾语指代物时是一个很常见且有效
的用法。
which加名词的用法
which加名词的用法
“which加名词”的用法有以下几种情况：
- “which”用来询问某一范围内的人或物，在句中可作主语、宾语和定语，作定语时，“which”后面要加名词，如“Which is yours？”“Which do you like better，the blue one or the red one？”“Which bag do you like？”。
- “which”作关系代词，作抽象名词mistake的限定词，相当于指示限定词（this、that、these、those），注意介词for因为关系词还是被提前了，但它的宾语不是“which”而是mistake。
类似的抽象名词先行词还有：fact、case、event、situation、time、failure、claim、point、mission等。
- “which”指代一个名词（词组）、一个短语，也可以指代整个句子，所修饰的名词（如time、case、city等）是对先行词的内容起概括作用的名词。
你可以根据具体的语境和表达需要来选择恰当的用法。

which的用法大全
1、在后置的非限制性定语从句中代替上文出现的事物或情况（单数或复数）。
2、在问句中作为疑问代词，在名词从句中作为连接代词用，其含义为“哪个、哪些”。
3、如果非限制性定语从句的先行词不是指主句内容，而是指具体的人、时间、地点，则不用which。
[解题过程] 这里主要讲解一下在定语从句中的用法：
一、关系代词that 和which 在定语从句中作主语和宾语，放在先行词和定语从句之间，起联系作用。
指物时，一般情况下可互换。
如： Here is the pen that/which you lost yesterday.(that/which 指物作宾语) A plane is a machine that/which can fly.(that/which 指物，作主语) He is the most careful boy that I know.(that 指人,作宾语) The man that works in this room is a chemist.(that 指人,作主语)
二、that,which 在从句中作主语时，不能省略。
作宾语时在口语中和非正式问题中经常省略。
如上例1 和中的that,which 都可省略。
三、关系代词在主语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。
Wheat is a plant that/which is grown in the north of China.
四、在定语从句中，关系代词that 和which 指物时，一般没有区别，但下列几种情况中不能互换：
只能用that 的情况：
a)先行词为 all,everything,nothing,anything,little 等不定代词时（something 后也可用which）：Is there anything (that) I can do for you in town That’s all (that) I know.
b) 先行词被序数词所修饰时： The first thing (that) we should do is to work out a plan.
c) 先行词被形容词最高级所修饰时： This is one of the most exciting football games (that) I have ever seen. The nanjing yangtse river bridge is the longest bridge
(that) they have ever seen.
d) 先行词被only,very,no,any,same,little,one of 等词所修饰时： This is the only thing (that) we can do now. He gave me the same pen (that) he borrowed from me. Do you have any books that were written by Lu Xun This is the very book (that) I want to read.
e) 当先行词中既有人又有物时： The man and the car (that) you want to see are all here. 你相见的人和车都在这里。
f) that 可指人，which 则不能： Who is the man that is reading the newspaper over there
g) 在“the time when”等结构和某些时间状语中，when 常被that 代替，而且that 往往省略： I may leave here any time I want to. During the time I was there I visited him twice.
h)way 后面可根由that 引导的定语从句，但that 一般都省略： That was the way she looked after us.
在下列情况中，只能用which:
a) 放在介词后面做介词宾语时： This is the question abo ut which we’ve had so much discussion. 但是，如把介词放在从句的后部，这时which 就可换为that 并常省略。
如上例可改为：This is the question (that) we’ve had so much discussion about.
b) 在非限制性定语从句，无论指物指人，都不能用that。
指物时，只能用which 和其他关系代词。
如： All the books there,which have beautiful pictures in them,were written by him.。
