定语从句which的用法例句

定语从句which的用法例句一、定语从句的概念和作用定语从句是英语中常用的一种复合句结构。

它用来修饰名词或代词，并且在整个句子中充当形容词的角色。

其中，连接定语从句和主句的关联词常见有that, which, who等。

例如：1. I have a friend who/that is very intelligent.我有一个非常聪明的朋友。

2. This is the book which/that I borrowed from the library.这是我从图书馆借来的那本书。

二、which引导的定语从句1. 正式场合介绍事物当我们需要在正式场合对某个事物进行介绍时，可以使用which引导的定语从句来加以说明。

例如：Recently, I bought a new car which has excellent fuel efficiency and a spacious interior.最近，我买了一辆新车，它具备着出色的燃油效率和宽敞的内部空间。

2. 强调前面所提到过的事物有时候，在强调之前提过的事物时，我们可以使用which引导定语从句，并将其放置于被强调部分之后。

例如：She had a lovely garden filled with beautiful flowers, which she took great pride in showing off to her friends.她拥有一个盛满美丽花朵的可爱花园，她为此自豪地向朋友们炫耀。

三、which引导的非限制性定语从句1. 进一步解释或补充信息非限制性定语从句用于进一步解释或补充前面提到的事物，并且不是必要的信息。

这类从句通常由逗号隔开。

2. 先行词为“those＋表事物的复数名词”时，关系代词通常只用which而不用that。

如：you should grasp well those skills which may be used in the future work.最后，记得这个特殊情况吧：当先行词是表示原因或方式的名词时，可以用that引导定语从句，相当于介词+which，that可以省略。

如： She likes the child for the very reason that (=for which) she loves his father. 她喜欢那个孩子因为她爱着孩子的父亲。

定语从句连接词which

定语从句连接词which定语从句连接词which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 t hat 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。

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)拓展：定语从句中的`that和which用法区别that和which在从句里都可以做宾语和主语，做宾语时可以省略。

定语从句中which的用法

定语从句中which的用法定语从句中which的用法定语从句中有时候需要用到which，那么定语从句中which的用法又是呢?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~下载全文。

（ 2 ） Which 在句法上一般用作实义动词的主语，这时它所引导的从句与主句之间常含有并列、因果关系；句法上， as 常作一些实义动词（如 see, know, report, watch, remember, say, tell, show, expert, guess 等）的宾语。

(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.。
