定语从句完成句子（精选8篇）
篇1：定语从句完成句子
自由式定语从句
自由式定语从句是指一个句子中两个或两个以上不同成分带定语从句的情况。这种从句的先行词没有固定模式，在句中充当不同的句子成分，故该结构中的定语从句称为自由式定语从句。它们拆开来看，其实就是一个一个简单的定语从句，因此，其翻译也和简单的定语从句相同。
Examples:
Thus the Arab Umayyed Dynasty of caliphs, which had moved the capital from Medina to Damascus in 661, came to be regarded with much justification as a parasitic clique that had outlived its usefulness once the conquests were completed.
Chinese Translation No. 1:
人们开始理由充分地认为，阿拉伯麦伍德哈里发王朝阿拉伯伍麦叶里发王朝是征服战争完成后毫无作用的一个寄生集团；该王朝曾于661年从麦地那迁都大马士革。
Chinese Translation No. 2:
阿拉伯麦伍德王朝的统治者们征服了……，于661年将首都从麦地那迁往大马士革，但此后他们便成了不折不扣的寄生虫。
嵌套式定语从句
嵌套式定语从句是指一个句子中定语从句套定语从句的情况。这种结构中的定语从句其实和自由式定语从句基本相似，拆开来也是一个独立的`定语从句，只不过一个定语从句在另一个定语从句之中而已。
Examples:
Likewise in the east were the Seljuk Turks who had infiltrated from their Central Asian homeland into the Islamic Empire where they were employed as mercenaries by the Baghdad caliphs.
Chinese Translation No. 1:
同样，在东方是塞尔柱突厥人，他们从家乡中亚进入伊斯兰教帝国；在那里被巴格达哈里发雇为雇佣军。
Chinese Translation No. 2:
东边也是塞尔柱突厥人。他们从自己的家乡中亚地区来到伊斯兰教帝国，充当了巴格达哈里发的雇佣军。
并列式定语从句
并列式定语从句是并列成分中的定语从句的简称，指一个句子中两个或两个以上并列成分均带定语从句的情况。
Examples:
This was a defensive pact, designed to protect Germany against the French, who aspired to recover the alsace-Lorraine provinces lost in 1871, and also to protect Austria-hungary against the Russians, with whom they continually clashed in the Balkans.
这是一个防御性的盟约，旨在保护德国人免受法国人的攻击，保护奥匈帝国免受俄国人的攻击；因为法国人想收复1871年失去的阿尔萨斯-洛林地区，而俄国人则在巴尔干半岛同奥匈帝国接连不断地发生冲突。
一主二仆式定语从句
Examples:
The old ways of earning a living was rivaled by new agricultural techniques, by commerce with hitherto unknown parts of the globe, and by new crafts with strange machines that saved labor and that ran without the traditional human or animal power.
古老的谋生之道正受到新农业技术、新贸易和新行业的挑战。其中，这些新兴的行业使用一些奇怪的机器。这些机器无需传统的人力和畜力，非常节省劳动力。

Not Surprisingly, the most complex political structures appeared in the Sudan, where long distance trade was most highly developed and where Islamic influence was the strongest.
Chinese Translation No. 1:
毫不奇怪，苏丹出现了最复杂的政治组织，在那里，长途贸易发展得最快，伊斯兰教的影响最为强烈。
Chinese Translation No. 2:
苏丹的长途贸易发展得最快，伊斯兰教的影响也最大。在那里出现最为复杂的政治组织是毫不奇怪的。

At one extreme are Hawaii and Brazil, where racial intermixture is extensive and continuing, and where racial discrimination is relatively minor.
Chinese Translation No.1:
处于一个极端的是夏威夷和巴西，在那里，种族混合十分广泛，而且正在继续进行，因此，种族歧视较少。
Chinese Translation No.2:
最为典型的则要数夏威夷和巴西了。在这两个地方，种族混合非常普遍，而且将会有增无减；而相对来说，种族歧视问题就不怎么严重了。

Prior to the twentieth century, women in novels were stereotypes of lacking any features that made them unique individuals and were also subject to numerous restrictions imposed by the male-dominated culture.
在20世纪以前,小说中的妇女像都是一个模式。她们没有任何特点,因而无法成为具有个性的人;他们还要屈从于由男性主宰的文化传统强加给他们的种种束缚。
Although perhaps only 1 per cent of the life that has started somewhere will develop into highly complex and intelligent patterns, so vast is the number of planets that intelligent life is bound to be a natural part of the universe.

篇3：定语从句完成句子
语法是语言的重要组成部分,必然是教师教学过程中的核心内容之一。在高中语法教学中,定语从句就是教师讲解的重点,却又是许多学生的语法学习中的短板。虽然学生们在初中阶段已经学过定语从句,多数能读懂含有简单定语从句的句子,但高中阶段对定语从句运用的能力要求更高,不仅要求学生理解其句法功能,还要求学生能运用定语从句进行书面表达。要求提高了,难度也随之增加。
英语和汉语中都有定语,英语中的定语从句是汉语中所没有的;而且中英两种语言的句型结构也有着巨大差异。这就对中国学生理解定语从句造成了一定的障碍。所以,课前学生必须清晰理解以下知识:
1. 主语和谓语是英语句子不可或缺的两个部分,除少数句子(如祈使句和感叹句等)外,一句话必须同时具备主语和谓语,所表达的意思才完整;在复合句中,主句和从句各自具有属于自己的独立的主语和谓语。
2.定语的概念:描述见表1。
3.英语中有5种简单句的基本句型,它们是构成一切长难句的基础。
观察例句,引出定语从句的相关概念
如果直接把概念化的东西平铺直叙给学生念一遍,语言学习会枯燥而无味,而且很突兀。这时,例句的展现,引导式的分析就很重要了,如:
The students(who do not study hard)will not pass the exam.
让学生观察例句,此时在教师的指导下找出主句的主干:The students will not pass the exam,即主谓宾结构。主语the students后的从句who do not study hard对其进行修饰限定,就是定语从句,它的作用类似形容词;其中who称作是关系代词,the students是先行词。由此可以得出定语从句的位置及相关概念(见表3)(这里的关系副词仅仅是呈现,不做讲解)
运用合并句子法,展现定语从句的演变
事实上,定语从句可以看做是两个简单句的合并,通过这样的演变,学生对于汉语中所没有的定语从句的出现会产生直观的印象,而且懂得定语从句使句子结构更加紧凑,表意更加丰富、精确。
请观察下面的例句,并将它们合并成为含有关系代词的定语从句:
1. A.Nature isone thing.
B.One thingreally must be experienced.
1)AB两句分别是主系表和主谓宾结构。根据句意(大自然是真正必须亲身体验的一种事物),以A句为主句,B句为从句,进行第一次直接组合:Nature isone thing(one thingreally must be experienced.)
2)显然,one thing是这两个句子的相同部分,主句中的one thing作先行词,从句重复部分用关系代词代替,指物用which/that,句子再次精简,合并:Nature isone thing(that/which really must be experienced.)至此,我们可以知道先行词与关系代词是对等关系,因为one thing在从句中作主语,所以关系代词that/which也作主语。
3)由此可以得出结论:that,which引导定语从句,指代先行词one thing,并充当定从中的主语。
用同样的方法对第2,3两组句子进行合并:
2. A.The girlis Anne.(主系表)
B.We sawthe girlyesterday.(主谓宾)
此组合并有两种情况,句意相同只是结构差异:
A句作主句:
1)The girl(we saw the girl yesterday)is Anne.(第一次直接组合)
3)The girl(whom we saw yesterday)is Anne.(调整关系代词位置,一般紧跟在先行词后面)
分析得出结论:whom引导定语从句,指代先行词the girl,并充当定语从句中saw的宾语。
B句作主句:
1)We sawthe girl(the girlis Anne)yesterday.
2)We sawthe girl(who is Anne)yesterday.
分析得出结论:who引导定语从句,指代先行词the girl,并充当定语从句中的主语。
3.A.Tu Youyou is ascientist.(主系表)
B.The scientist’sname is known all over the world.(主系表)
1)Tu Youyou isa scientist the scientist’sname is known all over the world.
2)Tu Youyou is a scientist whose name is known all over the world.(关系代词中只有whose有“……的”含义,表所属关系)
分析得出结论:whose引导定从,相当于the scientist’s,充当定语。
这时,可以把简单句合并成为定语从句的方法再次总结呈现:(1)找出两句中相同部分,确定主句、先行词;(2)从句重复部分用相应的关系代词代替;(3)适当调整句序,一般情况下,定语从句紧跟在先行词后。
通过观察,学生在教师的引导下分析与对比,在变化推导过程中明白英语中的定语从句究竟是怎样产生演变而来的,这样的过程自然而流畅;同时可归纳得出关系代词的作用:(1)引导定语从句(或者说连接主从句);(2)指代其前的先行词;(3)在从句中充当某种成份(主要是主语、宾语、定语)。
然后,教师给出相应的练习,让学生进行实战演练。注意:初学此种方法,给出的句子可遵循由易到难的规则。
拆分定语从句,分析关系代词的具体用法
反过来,定语从句可以拆分成为简单句,从而分析关系代词的具体用法。
1.如何使用which
1)A school buswhich carried 64 kidswas hit by a truck last week.
该句可以拆分成为:
A.A school bus was hit by a truck last week.(主谓)
B.A school bus carried 64 kids.(主谓宾)
2)Thefilm(which)we sawyesterday is interesting.
拆句:
A.Thefilm is interesting.(主系表)
B.We saw thefilm yesterday.(主谓宾)
通过前面的分析,关系代词与先行词是对等关系:a school bus=which,thefilm=which(以下例句可以同理推导),所以,教师可以轻松引导学生得出结论:which可以指代物,在定语从句中可以充当主语和宾语成分。
2. 如何使用that
3)English is a languagethat is used and learned by many people all over the world.
拆句:
A.English is a language.(主系表)
B.A language is used and learned by many people all over the world.(主谓)
a language=that
4)She is the girl(that)you saw in school.
拆句:
A.She is the girl.(主系表)
B.You saw the girl in school.(主谓宾)
the girl=that
小结:that可以指代物和人,在从句中作主语和宾语。
3. 如何使用who和whom
5)Thosewho reported the newswere expected to speak excellent English.
A.Those were expected to speak excellent English.(主谓宾)
B.Those reported the news.(主谓宾)
those=who
6)You can rely on the girl(whom)you talked with.
A.You can rely on the girl.(主谓宾)
B.You talked with the girl.(主谓宾)
the girl=whom
小结:who可以指代人,在定从中作主语;whom可以指代人,在定从中作宾语。
4. 如何使用whose
7)Don’t get too close to the house whose wall has big cracks.
A.Don’t get too close to the house.(主谓宾)
B.The house’s wall has big cracks.(主谓宾)
the house’s=whose
8)The boywhose name is Jackis in my class.
A.The boy is in my class.(主系表)
B.The boy’s name is Jack.(主系表)
the boy’s=whose
小结:whose可以指代人和物,以whose+n.形式出现,在定语从句中作定语成分。
课后延伸
句子赋予语法生命,在许多的优美句子和篇章中都有定语从句的身影。此时教师可以给学生提供这样的例子,让他们感受其无穷魅力的同时也激发他们努力学习运用定语从句的动力:
2.Whenever you feel like criticizing any one,just remember that all the people in this world haven’t had the advantage s that you’ve had.(The Great Gatsby)
3.To the man who only has a hammer,everything he encounters begins to look like a nail.(——Abraham Maslow)
结语
用合并句子来展现定语从句演变,拆分句子来分析关系代词的具体用法,充分体现了归纳法在语法教学中的作用。这篇文章对于高中生学习定语从句可以起到抛砖引玉的作用,让他们知其所以然。掌握好了这种方法,有关定语从句后续知识的学习自然是水到渠成的事了。

篇8：定语从句完成句子
[例句呈现]仔细阅读A、B两组句子，注意观察它们的不同点。
A.
1.The girl who came this morning is my sister.
2.Those who wish to go to the park must be at the gate by 7:50 am.
3.After living in Paris for fifty years he returned to the small town where he grew up as a child.
B.
1.Mr.Shang, who came to see me yesterday, is an old friend of my father’s.
2.Mary, whose children are at school all day, is trying to get a job.
3.He said that he had never seen her before, which was not true.
4.The college, where he studied for four years, is a famous one.
5.The 8:30 train, which is usually very punctual, was late today.
[小结]通过以上例句，我们可以发现：A组是限制性定语从句，B组是非限制性定语从句。限制性定语从句与非限制性定语从句主要有以下几个方面的区别。
1. 形式不同
主句和限制性定语从句之间不用逗号隔开，而主句与非限制性定语从句之间通常用逗号隔开。
2. 作用不同
限制性定语从句是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。这种从句和主句的关系十分密切，写时不用逗号分开。限制性定语从句中作宾语的关系代词常可省略，如：
a) What is the name of the tall woman who is standing there?
站在那边的那个女人叫什么名字?
b) Toronto is a city (that) I’ve always wanted to visit.
多伦多是我常想去参观的一个城市。
而非限制性定语从句和主句关系不十分密切，只是对先行词作些附加的说明，如果去掉，主句的意思仍然清楚。这种从句和主句之间往往用逗号分开，一般不用that引导。在非限制性定语从句中，关系词不可省略。如：
a) Rome, which is the capital of Italy, has a very long history.
意大利的首都罗马历史非常悠久。
b) Yesterday I met Professor King, who came from the University of London.
昨天我遇见金教授，他是从伦敦大学来的。
c) He lent me a dictionary, which was just what I needed.
他借给我一本词典，这正是我所需要的。
3. 先行词不同
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，而特殊场合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。
eg.A middle-aged woman killed her husband, which frightened me very much.
一个中年女子杀害了其丈夫，这事令我十分恐惧。
分析：从语境可知，令我恐惧的内容应为中年女子杀害了其丈夫这整件事，因此先行词为整个主句，此时应由which引导定语从句。
eg.A five-year-old boy can speak two foreign languages, which surprises all the people present.
一个五岁的男孩会讲两门外语，令所有在场的人感到非常惊讶。
分析：从语境可知，令所有在场的人感到惊讶的内容是一个五岁男孩会讲两门外语这整件事，因此先行词为整个主句，此时应由which引导非限制性定语从句。
4. 关系词不同
限制性定语从句可以由that, which, who (m), where, when, why及“介词+which/whom”等来引导，而非限制性定语从句通常由who (m), whose, which, when, where及“介词+which/whom”引导。
关系代词whom在限制性定语从句中作宾语时可用who代替whom，但在非限制性定语从句中作宾语时不可用who来代替。
eg.This is the girl whom I met in the street.
这是我在街上遇到的女孩。
先行词“the girl”在限制性定语从句中作宾语，可用who代替whom。
eg.A young man had a new girl friend, whom he wanted to impress.
一个年轻的小伙子新交了一个女朋友，他想给她留下深刻印象。
先行词“a new girl friend”在非限制性定语从句中作宾语，不可用who代替whom。
最后我们不妨比较一下以下两个句子：
a) She has two brothers who are working in the city.
她有两个弟弟在这个城市工作。(其意思是强调：She hasmore than two brothers.)
b) She has two brothers, who are working in the city.
她有两个弟弟，他们在这个城市工作。(而这句是说：Shehas only two brothers.)
下面两个句子只有一个逗号之差，意义却大相径庭。
a) He will wear no clothes which will make him different from others.
他不会穿一些使他显得与众不同的衣服。
b) He will wear no clothes, which will make him different from others.
