10、This is the last factory ___ he used to work at, many workers of _____ still have a good relationship with him.

D

限制性定语从句和非限制性定语从句练习题
The person who I met yesterday was friendly. (正确答案：The person, who I met yesterday, was friendly.)
改错题2
The book that I borrowed from the library is very useful. (正确答案： The book, which I borrowed from the library, is very useful.)
这句话中的定语从句是“that you lent me”，修饰先行词 “the book”，表示“你借给 我的那本书”。这是一个限制 性定语从句，因为它对“the book”进行了限定，说明是哪 一本书。
She has a brother, who is a doctor.
这句话中的定语从句是“who is a doctor”，修饰先行词“a brother”，表示“她的一个兄 弟”。这是一个非限制性定语 从句，因为它对“a brother” 进行了补充说明，而不是限定。
“to me”。
改错题2
She has a brother, and he is a doctor.
04 答案及解析
答案
限制性定语从句答案：C 非限制性定语从句答案：B
解析
限制性定语从句解析
题目中的限制性定语从句是“that you borrowed”，它用来修饰名词“book”，指明是哪一本书。在限制性 定语从句中，关系代词“that”充当宾语，指代被修饰的名词，不可省略。因此，正确答案是C。
改错题4
The place where I went on holiday was very relaxing. (正确答案：The place, where I went on holiday, was very relaxing.)
初中英语 非限制性定语从句练习题(含答案)
限制性定语从句作用：限制性定语从句是先行词在意义上不可缺少的定语，若去掉，所修饰主句的内容就不完整或失去意义。
这种从句和主句的关系十分密切，写时不可用逗号分开。
例：She has found the nacklace（that）she lost two weeks ago, 她找到她那条丢失两周的项链。
非限制性定语从句作用：非限定性定语从句的作用是对所修饰的成分作进一步说明注（：通常和主句间用逗号隔开，不受主句句子结构的影响，将从句拿掉后其他部分仍可成立）语法：1. that不能用于引导非限制性定语从句2. 有时as也可用作关系代词3. 在非限定性定语从句中，用who, whom代表人，用which代表事物。
4.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。
例1：Charles Smith, who was my former teacher, retired last year.查理·史密斯去年退休了，他曾经是我的老师。
例2：My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
例3：This novel, which I have read three times, is very touching.这本小说很动人，我已经读了三遍。
5.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

限制性非限制性定语从句详解+练习(附答案)
定语从句用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫作定语从句。
一．词引导的定语从句1. 关系代词用来指代先行词是人或物的名词或代词句子成分用于限制从句或非限制性从句只用于限制性从句代替人代替物代替人或物主语 Who which that主语 Whom which that宾语 Whose(=of whom) whose(=of which)例1：This is the detective who came from London.例2：The book which I am reading is written by Tomas Hardy.例3：The desk whose leg is broken is very old.例4：This is the room that Shakespeare was born in.2．关系代词的用法(1) 如果先行词是all, much, anything, something, nothing, everything,little, none等不定代词，关系代词一般只用that，不用which。
例如： All the people that are present burst into tears.(2) 如果先等词被形容词最高级以及first, last, any, only, few, much, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。
例如：(3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。
例如：There are about seven million people taking part in the election, mostof whom、are well educated.(4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。

非限制性定语从句练习
非限制性定语从句练习非限制性定语从句练习定语从句有限制性和非限制性两种。
限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。
下面我们来看看非限制性定语从句练习的内容吧!一、that不能用来引导非限制性定语从句。
如：【考例一】She heard the terrible noise, ________brought her heart into her mouth.A. itB. whichC. thisD. that【解析】选B。
后半句为非限制性定语从句，尽管先行词noise属于事物，也不能用that而要用which来引导。
which指代noise，在从句中作主语。
二、除which外，还可用when，where，whose，whom等引导非限制性定语从句，且各自的'用法及差异与它们用在限制性定语从句时相同。
如：Next month, when you'll spend your summer holidays in your hometown, is approaching. 下个月即将来临，届时你们将在家乡度暑假。
(关系副词when指代表示时间的名词next month，并作从句的状语。
)She is going to live in Macao, where she has some close friends. 她要到澳门去居住，在那里她有几个密友。
(关系副词where 指代表示地点的名词Macao，并在从句中作状语。
)【考例二】Recently I bought an ancient Chinese vase, ________was very reasonable.A. which priceB. the price of whichC. its priceD. the price of whose【解析】选B。
(完整word版)限制性与非限制性定语从句及练习
限制性与非限制性定语从句区别一、在句中作用不同限制性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。
限制性定语从句不能被省略，否则句意就不完整。
非限制性定语从句与先行词关系不十分密切,只是对其作一些附加说明,不起限定制约作用。
如果将非限制性定语从句省去，主句的意义仍然完整.二、外在表现形式不同限制性定语从句因与先行词关系密切,所以不可以用逗号将其与主句隔开；而非限制性定语从句与先行词关系不十分密切,所以可用逗号将其与主句隔开.例 1。
Do you remember the girl who taught us English?你还记得教我们英语的那个女孩吗？例 2. Clock is a kind of instrument which can tell people time。
钟是一种能够告诉人们时间的仪器。
例 3。
This is the place where he used to live.这就是他过去居住的地方。
例 4. Mr. Zhang, who came to see me yesterday， is an old friend of mine.张先生昨天来看我,他是我的一位朋友.例 5. We walked down the village street, where they were having market day。
我们沿着村里的大街向前走去,村民们正在那里赶集.析：在前三个例句中,定语从句与先行词关系密切,为限制性定语从句,不可用逗号将其与主句隔开。
在后两个例句中,定语从句与先行词关系不密切，为非限制性定语从句，可用逗号将其与主句隔开.三、先行词内容有所不同大多数限制性和非限制性定语从句的先行词往往为某一个词或短语，而特殊情况下非限制性定语从句的先行词也可为整个主句，此时非限制性定语从句常由 which 引导。
例 1. A middle—aged woman killed her husband， which frightened me very much.一个中年女子杀害了自己的丈夫,这令我十分恐惧.析：由语境可知，令“我"恐惧的内容应为“中年女子杀害了自己的丈夫”这整个一件事,因此先行词为整个主句,此时应由 which 引导定语从句.例 2. A five—year-old boy can speak two foreign languages, which surprises all the people present.一个五岁男孩会讲两门外语,这令所有在场的人感到非常惊讶。
