定语从句(八年级上)讲解、训练【三套】(有答案与解析)
定语从句（八年级上）讲解、训练【三套】（有答案与解析）一、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句。
如：1) The man who lives next to us is a policeman.2) You must do everything that I do.上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。
引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why。
关系词常有三个作用：1、引导定语从句2、代替先行词3、在定语从句中担当一个成分二、关系代词引导的定语从句1.who指人，在从句中做主语(1)The boys who are playing football are from Class One.(2)Yesterday I helped an old man who lost his way.如果先行词是anyone, anybody, everyone, everybody, someone, somebody,关系代词应该用who 或whom. 例：Is there anyone here who will go with you?2. whom指人，在定语从句中充当宾语，常可省略。
--(1) Mr. Liu is the person (whom) you talked about.注意：关系代词whom在口语和非正式语体中常用who代替，可省略。
(2) The man who/whom you met just now is my friend.3. which指物，在定语从句中做主语或者宾语，做宾语时可省略(1) Football is a game which is liked by most boys. ( which 在句子中做主语)(2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语)4. that指人时，相当于who或者whom；指物时，相当于which。

（完整版）定语从句归纳及专项练习题
（完整版）定语从句归纳及专项练习题定语从句语法归纳及练习一、语法知识归纳一、基本概念（一）定语从句在复合句中作定语，修饰名词或代词的从句叫定语从句。
（二）先行词被定语从句所修饰的名词或代词。
一般情况下，定语从句紧跟先行词。
但也有因各种原因定语从句与先行词被分割的现象。
（三）关系代词和关系副词定语从句的引导词。
与先行词关系密切，因此紧跟先行词，并在定语从句中充当一个成分。
关系代词有：who, whom, which, that和whose, 另外，as也可充当关系代词。
关系代词在定语从句中充当主语、宾语、表语和定语。
关系副词有：when, where和why。
在定语从句中充当状语。
二、关系代词的用法（一）基本用法根据先行词的不同，和在从句中所充当的成分不同，选用不同的关系代词。
例如：（注意关系代词在定语从句中所充当的成分）①Do you know the professor who/that will give us a speech next week? （作主语）②I read a report about his new novel that/ which will soon be published. （作主语）③The plan that/which they argued about was settled at last. （作宾语）④This is the new secretary (who/whom/that) I would like to introduce to you. （作宾语）⑤The soldier whose legs were badly wounded was operated on without delay. （作定语）注意：关系代词在定语从句中充当宾语时可以省略，充当主语时则不能。
（见上例③④）（二）关系代词that代替which的一些情况which, that 在代替物时，一般可以通用。

初中英语定语从句专项讲解与练习
初中英语定语从句专项讲解与练习初中英语定语从句系统讲解及配套练（含答案）一．定语从句的概念在复合句中，修饰某一名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面.二、定语从句的关系词关系词常有3个作用：1，引导定语从句。
2，代替先行词。
3，在定语从句中担当一个成分。
引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that，which，who（宾格whom，所有格whose）等;关系副词包括where，when，why等。
关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
三、定语从句的分类根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。
1.限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，限定性定语从句是先行词在乎义上不成短少的定语，假如去掉的话，主句的意义就不完全，意义就表述不明。
这类句型普通定语从句紧接先行词，如：I was the only person in myoffice who was invited.2.非限定性定语从句主句与从句之间有逗号分隔，起弥补申明感化，如省去，意义仍完全。
非限制性定语从句。
它与主句的关系不十分密切，只是对其附加说明，也就是讲即便去掉定语从句，句意也不受影响，仍然清晰明了。
这样的定语从句要在它和主句之间加一逗号分开。
且关系代词不引导这种非限制性定语从句，如：Michael Jaskon，who is the greatest singer in the world，passed away in 2010.如：Mary lived in the city of Hongkong，where used to be a small poor countryside.4、干系代词的用法1.that既可以用于指人，也可以用于指物。
在从句中作主语或宾语，作主语时不可省略，作宾语可省略。

2．The old town has narrow streets and small houses _____are built close toeach other.A．who B．that C．what D．They【答案】B【解析】试题分析：句中先行词为small houses，在定语从句中作主语，故用关系代词that。

考点：考查定语从句的用法3．Children like stories _______have happy endings, and so do many old people.A．who B．which C．what【答案】B【解析】【详解】句意：孩子们喜欢有美满结局的故事，许多老人也是。
who引导定语从句，修饰人；which 引导定语从句，修饰事物；what引导名词性从句。
此处修饰先行词stories的定语从句，修饰事物，故用关系代词which引导定语从句。
故选B。
4．The girl ________ an English song in the next room is Tom’s sister.A．who is singing B．is singing C．sang D．was singing【答案】A【解析】【详解】句意：正在隔壁房间唱英文歌曲的女孩是汤姆的姐姐。

定语从句讲解与练习(有答案)
定语从句定语从句在句中相当于一个形容词，起定语的作用，修饰说明名词、代词或主语的全部内容。
通常在被修饰的词语（即先行词）之后，由“关系词”引导。
定语从句的三种功能：1.连接功能：连接从句，引导一个定语从句2.指代功能：指代先行词3.语法功能：在定语从句中充当句子成分(定语从句中的关系词分为关系代词和关系副词两种)that which who whom whose when where why注: 关系代词在句中充当主语、宾语，因此定语从句中不能再出现关系代词所替代的名词或代词。
1.关系代词在从句中作主语时不能省略① A plane is a machine which / that can fly . (作主语)The dog which / that was lost has been found . (作主语)②The number of people who / that lost homes reached 250,000 .Here comes the girl who / that wants to see you .2.|3.关系代词在句中作宾语时可省略①The noodles that / which I cooked were delicious .（作宾语）This is the book that / which I want to read .The letter that / which I received yesterday was from my father .②The girl who / that we saw yesterday is Mary .Mr Li is a man whom / who / that we should lear from .Do you know the man whom / who / that is talking to4.关系代词在从句中做定语①The novel whose cover was broken blongs to me .②Henery is the boy whose mother is our English teacher .\I know the person whose company produces computers .This is the person whose story surprised everybody .5.关系代词在句中作表语时可省略（只能用that）She is not the girl that she was .【定语从句中关系代词与关系副词的选择】1.明确关系代词，关系副词在定语从句中的不同作用关系代词which , that , who在定语从句中作主语或在及物动词或介词后作宾语关系副词when , where, why在定语从句中作状语，即定语从句中不缺主语、宾语，只缺时间、地点或原因状语2.分析句子结构，明确句法成分~关系词在从句中作宾语还是作状语，关键取决于从句中的谓语动词。
英语定语从句专项训练100(附答案)含解析
英语定语从句专项训练100(附答案)含解析一、定语从句1．Most students like the teachers understand them well.A．which B．who C．where D．when【答案】B【解析】试题分析：句意：绝大多数的学生都喜欢能够很好理解他们的老师。
分析：考查定语从句的用法，先行词是the teacher,先行词在从句中作主语，因此引导词用who.故选 B考点：考查定语从句的用法。
2．The We Chat is an invention can help people talk to friends, share photos, ideas and feelings freely.A．which B．who C．whose D．/【答案】A【解析】试题分析：句意：微信是可以帮助人们和朋友自由地聊天，分享照片，想法和感觉。
这是一个定语从句，先行词是物invention，关系词可以用which或者that，但是先行词在从句做主语，that不可以省略。
故选A。
考点：考查定语从句的用法。
3．The old town has narrow streets and small houses _____are built close toeach other.A．who B．that C．what D．They【答案】B【解析】试题分析：句中先行词为small houses，在定语从句中作主语，故用关系代词that。
句意：老镇有狭窄的街道，小房子建得彼此相靠近。
考点：考查定语从句的用法4．Success will belong to those never say “impossible” .A．whom B．what C．who D．Which【答案】C【解析】试题分析：句意：成功属于那些永远不说不可能的人。
此处考的是定语从句，先行词是those那些人，而且关系代词在句中做主语，所以用who，选C；whom可指代人，但做宾语；which只能指物，故选C。
定语从句语法讲解+含习题（含答案）
定语从句语法讲解+含习题（含答案）定语从句一、知识点梳理充当定语修饰名词或代词的从句称为定语从句。
被定语从句修饰的名词或代词称为先行词。
定语从句一般紧跟在先行词之后，由一定的连接词引导，连接词称为关系代词（which,that,as,whom,who,whose）或关系副词（when,where,why）1、限定性定语从句和非限定性定语从句⑴限定性定语从句起对先行词进行限定、区分的作用。
若去掉易产生歧义或使主句意义不明确。
（此类定语从句前后没有逗号）【eg】The dress that my mother bought for me is very beautiful.我妈妈给我买的裙子很漂亮。
⑵非限定性定语从句与先行词之间的关系比较松散，只对先行词起说明和描述的作用。
若省去，剩余部分意义仍然完整，表达清楚。
（此类定语从句前后用逗号隔开）【eg】Your writings , which everyone admires , are very marvelous.你的作品人人欣赏，实在是太了不起了。
Shakespeare , whose plays are popular , was a great writer.莎士比亚是个伟大的作家，他的剧作很受欢迎。
⑶某些情况下，一个定语从句既可以作限定性定语从句，又可以作为非限定性定语从句，但二者含义有差别。
【eg】There are ten cars here which are made in China.这里有十辆中国制造的车。
（这里可能还有其他的车）There are ten cars here , which are made in China.这里有十辆车，它们都是中国制造的。
（这里只有十辆车）⑷that和why一般不引导非限定性定语从句，其他引导限定性定语从句的关系代词和关系副词都可以引导非限定性定语从句。
【eg】My elder brother , who is an engineer , is working abroad.我的哥哥在国外工作，他是一个工程师。
定语从句讲解及百道经典习题
定语从句定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which等。
关系副词有：when, where, why等。
一、关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Is he the man who/that wants to see you?他就是你想见的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。
（whom/that在从句中作宾语）2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。
Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。
3）which, that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。
（which / that在句中作宾语）The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。

(2024版)中考定语从句讲解与练习
可编辑修改精选全文完整版中考定语从句讲解与练习一、定语从句的概述在复合句中修饰或限定名词、代词的从句叫做定语从句。
被定语从句修饰或限定的名词、代词叫做先行词；引导定语从句的词叫做引导词。
定语从句放在所修饰、限定的词（先行词）之后。
例1：The boy who is reading a story book is my brother. 那个正在读一本故事书的男孩是我的兄弟。
在这句话中，who is reading a story book.是定语从句。
它修饰、限定the boy，the boy是先行词，引导定语从句的who是引导词。
二、定语从句的分类：定语从句可分为限制性定语从句和非限制性定语从句。
1. 限制性定语从句一般紧跟在先行词的后面，用来说明先行词的性质、身份、特征等状况，与先行词的关系非常密切，翻译时一般要译到先行词的前面；如果去掉，则整个句子的意思含混不清。
A doctor is a person who looks after people's health. 医生是照顾人们健康的人。
2. 非限制性定语从句起到补充说明作用，译为汉语时常不译作定语，而是根据句意译为相应的其他形式的从句。
它与主句的关系不如限制性定语从句密切，只是对先行词作附加说明，既使去掉，主句的意思依然清楚。
非限制性定语从句前往往有逗号与主句隔开，如非限制性定语从句放在句子中间，其前后都需要用逗号与隔开。
Yesterday, Jimmy left for Canada, where he had stayed two years.昨天，吉米动身到加拿大去了，他曾在那儿呆了两年。
三、定语从句的引导词引导定语从句的词称为引导词，它一方面连接先行词和定语从句；别一方面又在定语从句中充当句子成份，引导词一般不能按照疑问代词或疑问副词的意义进行翻译，一般情况下应译为“……的”。
定语从句的引导词可为分为关系代词和关系副词。
定语从句讲解和定语从句专项练习题含答案(学霸总结精品资料)-10页
定语从句讲解1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。
关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。
关系词常有3个作用：1，引导定语从句。
2，代替先行词。
3，在定语从句中担当一个成分。
注：关系代词有主语.宾语之分。
一般whom作为宾语。
4.定语：定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语或句子，汉语中常用‘……的’表示。
主要由形容词担任。
此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任．单词作定语时通常放在它所修饰的词之前，作前置定语。
短语和从句作定语时则放在所修饰的词之后，作后置定语。
（一）限定性定语从句一、关系代词（在句中作主语、宾语或定语）1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。
[eg：this is the book （which）you want。
]而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括当先行词是anything, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, much 等修饰时等，这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与of which 调换,表达的意思一样。
中考英语专题讲练定语从句(含解析)
定语从句一、定义在复合句中，修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，通常位于定语从句之前。
引导定语从句的有关系代词who, whom, whose, which, that 等和关系副词where, when, why 等，关系代词和关系副词，既起到连接作用，又在定语从句中担任句子成份。
总结定语从句的一般结构为：先行词+关系词+定语从句。
一、关系代词1. 关系代词指代先行词，在从句中作主语，宾语或表语，基本用法如下表： 关系词作用先行词例句who主语/宾语人This is the boy who often helps me. 这就是帮我的那个男孩。
I happened to meet the professor (who/ whom) I got toknow at a party in the shopping center yesterday.昨天在购物中心，我碰巧遇到了那位我在一次聚会上认识的教授。
whom宾语人The man whom you are waiting for has gone home.你等那个人已经回家了。
定语从句知识精讲注意：一般情况下，that既可以指人又可以指物，可以代替who, whom和which，在句子中充当主语，宾语或表语；which指物，在从句中也做主语，宾语或表语，所以which和that在指物时，大多时候可以互换，如：This is the movie that I like best.=This is the movie which I like best.这就是我最喜欢的电影。
2. 关系代词的省略一般情况下，关系代词作宾语时可以省略，但若关系代词在从句中作介词宾语，且介词在关系代词前，不能省略，如：I’ll never forget the day that we spent together.我永远都不会忘记与你共度的时光。
定语从句讲解及巩固练习(有答案)
定语从句讲解及巩固练习一、定语从句的概念关系词（引导定语从句）↑1.People who have the highest EQ are the most successful↓先行词(被修饰词)二、定语从句的分类1. 限制性定语从句: 与先行词关系密切, 如果没有定语从句, 主句不完整, 且与先行词之间无逗号。
2. 非限制性定语从句: 对先行词起补充说明作用, 如果删除, 主句意义仍然完整, 与先行词之间有逗号。
eg: On the desk there are twenty books, three of which are mine.My aunt Alice ,whom I haven’t seen for years, is coming next month.★ that不能用于非限制性定语从句。
三、定语从句的关系词1. 指人的关系代词: who / whom / that1) 先行词在从句中作主语eg: A doctor is a person who / that looks after people’s health.2) 先行词在从句中作宾语eg: Mr White invited many friends to his party (who / whom / that) he respected much.3) 关系代词前有介词eg: Nancy is the right person on whom you can depend.小结：⑴ 指人的关系代词中，在从句中充当主语的是who和that,且在句中不可以省略。
⑴ 指人的关系代词中, 在从句中充当宾语的是who，that和whom，且可以省略。
⑴ 当关系代词前有介词时，指人只能用whom。
2. 指物的关系代词: which / that1) 先行词在从句中作主语eg: The river which / that runs through the city brings us lots of pleasure.2)先行词在从句中作宾语eg: The book (which / that) you just laid on the shelf is mine.3)关系代词前有介词eg: Here is the money with which I will buy a piano.3. 表示所有格：whose (既表示人的所有也表示物的所有)1) 表示人的所有eg: The girl whose father is a model worker is our monitor.2) 表示物的所有eg: I’d like a room whose window looks out over the sea.弄清as和which引导的非限制性定语从句指代整体时的区别★位置上的区别：as引导的非限制性定语从句的位置比较灵活，可以放在主句前，也可以放在主句后，还可插在主句的中间；而which引导的非限制性定语从句只能放在主句之后。

当先行词有the only, the very, the same, the last等修饰时。例如：
