定语从句的详细讲解与练习 新课标 人教版-新人教版高一全册英语试题
定语从句讲解和练习定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。
状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以与行为方式状语从句。
名词从句包括主语从句，宾语从句，表语从句和同位语从句与there be句型。
一、限定性定语从句1. that即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在从句中作宾语如此不能省略。
而且，如果which在从句中作“不与物动词＋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，但有的如此放在它原来的位置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，但在带有如下词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略4. 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. where是关系副词，用来表示地点的定语从句6. when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when 引导，有时不用任何关系代词，当然也不用that引导By the time you arrive in London, we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to business trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.7. 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8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导二、非限定性定语从句：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，通常和主句间用逗号隔开，将从句拿掉后其他局部仍可成立1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一局部2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at whiche.g. Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed.人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

人教必修一Unit 4 定语从句之关系代词(解析版)
第09练定语从句之关系代词定语从句的先行词和关系词在复合句中作定语，修饰主句或主句中某一名词或代词的从句叫定语从句。
定语从句由关系词引导。
限制性定语从句表现为在意义上是先行词不可缺少的定语，若省略，主句的内容就不完整或失去意义；它和主句的关系十分密切，不可用逗号分开。
先行词是被定语从句修饰的名词或代词。
关系词指代先行词，在从句中作一定的句子成分。
引导定语从句的关系代词有which，that，who，whom，whose，as等。
先行词是定语从句修饰和限定的成分，从构成上而言，它可以是名词、代词、名词性短语等；从句子成分上而言，它可以是主句的主语、宾语、表语等。
下面，我们从两个实例来看一下定语从句及其相关成分的分布：1.关系代词that即指人又指物；作主语或宾语（作宾语时可省略）只用于限制性定语从句中，介词后面不能跟that。
当代替物时，可以与which通用。
Yesterday Emily was wearing the new dress that I gave her．昨天艾米丽穿了我送给她的新衣服。
I have a friend that likes listening to classical music我有个朋友喜欢听古典音乐。
2.关系代词which指物；作主语或宾语（作宾语时可省略）在非限定性定语从句中，只宜用which,不能用that.在限定性定语从句中，可用在介词之后。
My parents live in a house which is more than 100 years old我的父母住在一座具有100多年历史的房子里who,whom指人；作主语或宾语（whom常可省略）先行词必须为人。
Who可代替在从句中担任宾语的whom,若前有介词，须用whomA couch potato is a person who spends a lot of time watching TV．“A couch potato”指那种成天沉湎于电视中的人。

本文将主要讲解关系代词引导的定语从句，并解释关系副词引导的定语从句，包括判断关系代词与关系副词限制性和非限制性定语从句等内容，并提供例题讲解。
定语从句在句中作定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。
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。
它们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。
当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。
例如，当先行词是人时，可以使用who或whom作为关系代词。
如：Is he the man who/that wants to see you?（他就是你想见的人吗？）关系代词在从句中作主语。
而当先行词是物时，可以使用which或that作为关系代词。
如：The package（which / that）you are carrying is about to come unwrapped.（你拿的包快散了。
）关系代词在从句中作宾语。
除了who。
whom。
whose。
that。
which，还有关系副词when。
where。
why等。
关系副词引导的定语从句也可以修饰一个名词或代词。
例如：I still remember the day when we met.（我仍然记得我们相遇的那一天。
）关系副词when在从句中作时间状语，修饰先行词day。
总之，掌握定语从句的用法和关系词的选择是英语研究的重要内容。
通过不断的练和实践，相信大家可以掌握这一技能。
关系副词可以代替时间、地点或理由的名词，在从句中作状语。
例如，关系副词when。
where。
why的含义相当于“介词+ which”结构，因此常常和“介词+ which”结构交替使用。
比如，有时候我们必须屈服，这是任何人都会遇到的情况（There are ns when [on which] one must yield）。
人教版高一英语定语从句练习题20题含答案解析
人教版高一英语定语从句练习题20题含答案解析1. I like the book ______ was written by Lu Xun.A. thatB. whichC. whoD. whom答案解析：A。
在这个句子中，先行词是“the book”，表示物。
关系代词在定语从句中作主语，既可以用“that”也可以用“which”。
但是当先行词被“the”修饰时，关系代词用“that”更为合适，所以这里选A。
C选项“who”和D选项“whom”都是指人，不符合先行词是物的要求，B选项“which”虽然可以指物，但在这里“that”更优。
2. The girl ______ I met yesterday is my classmate.A. thatB. whichC. whoD. whom答案解析：C。
先行词是“the girl”，指人。
关系代词在定语从句中作宾语，并且在从句中是主动关系，“whom”也可以指人作宾语，但在口语和非正式文体中，“who”可以代替“whom”，所以这里选C。
A选项“that”虽然也可以指人，但在这里“who”更常用。
B选项“which”指物，不符合要求。
3. This is the house ______ my grandparents lived.A. thatB. whichC. whereD. who答案解析：C。
先行词是“the house”，表示地点。
在定语从句中，关系词在从句中作地点状语，而不是作主语或宾语，所以要用关系副词“where”，而不是关系代词“that”“which”（ 它们在从句中作主语或宾语），D选项“who”指人，不符合要求，所以选C。
4. Do you know the man ______ car was stolen last night?A. thatB. whichC. whoD. whose答案解析：D。
先行词是“the man”，在定语从句中，我们需要一个表示所属关系的关系代词，“whose”表示“某人的”，在这里表示“那个男人的车”，A选项“that”、B选项“which”不能表示所属关系，C选项“who”在从句中作主语或宾语，不能表示所属关系，所以选D。

人教版高一英语定语从句全面讲解与练习
定语从句定语：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;例如 a clever boy the boiling water fallen leaves•The boy in the classroom needs a pen.•The man standing there is my teacher.定语从句：一个句子充当定语The boy who is reading needs the pen.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;Ⅰ. 概念：1 定语从句：在主从复合句中用作定语的从句叫定语从句;定语从句一般紧接在先行词后面;2 先行词：被定语从句修饰的成份;先行词可以为一个词,短语,或整个主句;3 关系词：引导定语从句的词,并代替先行词在从句中担任一定的成分;分为关系代词和关系副词;4 定语从句基本构成：先行词+关系词+从句A 关系词的作用：1 引导定语从句,连接主句和从句,相当于一个连词；2 必在从句中作某个句子成份可以做主语,宾语,表语,定语,状语1.The student who answered the question was John.2. I know the reason why he was so angry.3. The boy whom you are talking to is my brother.4. I’d like a room whose window looks out over the sea.B简单句变定语从句例1：The girl is Mary. The girl is standing there.The girl who is standing there is Mary.如何改写定语从句1、找准主句和从句,并找出两个简单句的共有成分,确定先行词;2、将从句中的共有成分去掉;3.找准关系词,用关系词引导从句剩下的部分,并紧接在被修饰词先行词之后;例2：A plane is a machine. The machine can fly.例3：The girl is Mary. We saw her yesterday.C定语从句选择关系词三步曲：第一找出先行词；第二看先行词在定语从句中的语法功能做主语、宾语或状语；第三选择合适的关系词;Ⅱ. 几个关系代词的基本用法：●that: 可指人或物；在定语从句中作主语,宾语,表语;指人时,相当于who或whom；指物时,相当于which 一般不用于非限制性定语从句; 不可置于介词后作宾语如：1. A letter that/which is written in pencil is difficult to read. 主语2. Do you know the gentleman that/who spoke just now3. You can take anything that you like. 宾语4. What is the question that/which they are talking about5. Here is the man who/whom/that you want to see.●which: 指物；在定语从句中作主语,宾语如：1. The book which/that was on the desk was bought by my father.主语2. The book which/that I bought yesterday is very interesting.宾语3. He was proud, which his brother never was. 表语●who, whom, whose:who: 主格, 在从句中作主语,在口语或非正式用法中作宾语; 只可指人whom: 宾格,在从句中作宾语; 只可指人whose: 属格,在从句中作定语,可指人也可指物;I like the students who/that work hard. 主语All who heard the story were amazed. 代词如he, they, any, those, all, one等后多用who.He's a man from whom we should learn. 宾语= He's a man whom/who/that we should learn from.A child whose parents are dead is called an orphan.指人I'd like a room whose window faces south. 指物whose +n. =the +n. + of which 物= of which 物+ the +n.=I'd like a room of which the window faces south. whose + n. =the +n. + of whom人= of whom人+ the +n.=I'd like a room the window of which faces south.注意：定语从句中的谓语动词的单复数于先行词保持一致This is one of the best books that have ever been written.He is one of the students who study hard at school.当one前面有the only等限定词和修饰语时, 定语从句的谓语动词要与one保持一致而取单数形式例如This is the only one of the best books that has ever been written.He is the only one of the students who studies hard at school.Ⅲ. 几个易混淆的关系代词的比较:●宜用that, 而不宜用which 的情况.①先行词为不定代词表示物,all, much, something, everything, anything ,nothing, none, the one等,②先行词被only, any, few, little, no, just, very, one of等词修饰时;③先行词是序数词时或被序数词修饰时;④先行词是最高级或被最高级修饰时;.⑤先行词既有人又有物,用which和who都不适合,这时宜用that. 如：⑧主句是There be 结构,修饰其主句的定语从句宜用that 作关系代词. 如：1. There is still a seat in the corner that is still free.⑨被修饰成分为表语时,或者关系代词本身是定语从句的表语时,该关系代词宜用that .2. My home village is no longer the place that it used to be .●定语从句中宜用which而不宜用that 的情况:①当关系代词的前面有介词时.1.A zoo is a park in which many kinds of animals are kept for exhibition.②在非限制性定语从句中.1.Crusoe's dog, which was are now very old, became ill and died .2.More and more people are beginning to learn English, which is becoming very popular in our country. which 指代主句B who & that:● who 和that 指代人时,有些情况宜用who, 而不宜用that①先行词为anyone, anybody, those, all, one, ones, they, he, people时. 如：.②在There be 结构中,修饰主语的定语从句宜用关系代词who 指代人. 如：1.There is a gentleman who wants to see you .Ⅳ.关系副词引导的定语从句:●When 指时间,在定语从句中作时间状语;定语从句中when=in/on/at which, 其先行词是表时间的名词如：time, day, week, tear, month, etc.I still remember the day when /on which my brother joined the army.作状语I shall never forget the day when Shen Zhou Ⅴwas launched, which has a great effect on my life.I still remember the days which/that we spent together. 作宾语Next winter which/that you'll spend in Harbin, I'm sure, will be exciting.●Where 指地点,在定语从句中作地点状语;定语从句中where=in/on/at which,其先行词是表示地点的名词,如：place, school, factory, room, etc.This is the factory where /in which he worked last year. 作状语This is the place where I was born.This is the park which/that they visited last year. 作宾语I live in the room which was bought by my father.I think you have got to the point where a change is needed, or you would fail.He's got himself into a dangerous situation where he's likely to lose control of the plane.●Why 指原因,在定语从句中作原因状语;先行词为reason 时,可用for which指代；如：That’s the reason why/for which he was late.The reason why / for which he didn't attend the meeting was that he was ill.I don't believe the reason that/which he gave me. 作宾语Have you asked him the reason t hat may explain his success 作主语当先行词为way时,关系词在句中作状语时,定语从句常用that, in which引导,that常可以省略;way后的定语从句的引导词不用时较多;但如果关系词在句中作主语或宾语时,则用which或that 引导;如:This is the way that /in which I do such things.比较: Please do the experiment in the waythat/whichI have shown you.V.介词+关系代词考点1.基本考点考点1 简单介词+关系代词引导定语从句时,that和who不能用于介词之后,能用于介词＋关系代词引导定语从句的代词只有which和whom;考查“介词+ 关系代词”引导的定语从句,关系代词前该选什么样的介词,要根据不同的语境、词组搭配、习语、惯用法等来决定,归纳起来介词的选择主要依据如下几点：①介词与定语从句的先行词搭配;如：The farm on which I once worked has taken on a new look．on the farm②介词与从句中动词搭配;如：Who is the man with whom our teacher is shaking hands shake hands with sb.In the dark street there wasn’t a single person to whom she could turn for help. turn to sb. for help③介词与定语从句中的形容词搭配,如：The west lake, for which Hang Zhou is famous, is a beautiful place. be famous for④根据句子的意思来决定, 此时不但要注意其前的搭配也要注意其后的搭配;Water is very important for us without which we can’t live.2004辽宁The factory produces half a million pairs of shoes every year, 80% of which are sold abroad．2006辽宁I was told that there were about 50 foreign students studying Chinese in the school, most of whom were from Germany.The old man has two daughters．Both of them are doctors．那位老人有两个女儿,她们都是医生;③as 常用在as we all know；as you know; as is known to all; as you see; as we can see; as has been expected 等结构中;例如：一般译为"正如""就像","这一点"As we all know, smoking is harmful to one's health . as 作宾语=As is known to all, smoking is harmful to one's health . as 作主语=It's known to all that smoking is harmful to one's health .=Smoking is harmful to one's health, as we all know .as 作宾语Jack has won the first prize, as often happens. 像往常一样,Jack得了一等奖;训练题汇总◆EX1用适当的关系词填空.1.

This is the point that they disagree with. This is the point with which they disagree. That is the house that they spent much money on. That is the house on which they spent much money.
定语的位置一般有两种：用在所修饰词之前 的叫前置定语，用在所修饰词之后的叫后置定语。 单词作定语时通常放在它所修饰的词之前， 作前置定语。副词，短语和从句作定语时则放在 所修饰的词之后，作后置定语。

高中英语人教版必修上册期末复习定语从句知识讲解与练习
高中英语必修上册定语从句知识讲解练习一、关系代词和关系副词的选择在选择使用具体的关系代词和关系副词时，有两点需要同时考虑：一是先行词的性质，是指人还是指物，是指时间、地点、方式还是原因；二是关系词在从句中作什么成分，关系代词可在从句中作主语、宾语、定语（whose后紧跟名词）或表语（表语相对较少），关系副词在从句中只能作状语。
二、关系代词的省略在限制性定语从句中，如果关系代词在从句中充当宾语，一般可以将关系代词省略。
三、“介词+关系代词”的运用（1）只是把从句中动词短语中的介词提前有些短语是整体表意，就不能拆分，如look after, take care of等）Who is the man to whom you just spoke?（只是将短语speak to中的to提前）（2）“介词+关系代词”等同于某个关系副词。
比如关系副词when根据具体语境可以替换为“in which”“at which”“on which”, where 一般可替换为“in which”，why一般可替换为“for which”, 使用哪个介词要根据先行词的惯常搭配。
I will always remember the day when/on which he came to see me.（具体的某一天用on搭配）1964 , when/in which China exploded its first atom bomb, was of great significance to us.（在某一年用介词in）（3）有些“介词+关系代词”不能替换成关系副词。
情况一：“介词+关系代词”前面还有其他的限定词（比如all，each，both等）。
There are 40 students in this class, all of whom come from poor families.情况二：关系代词指代前面整句话，介词用来表明主句和从句的关系。

定语从句定语：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。
例如 a clever boy the boiling water fallen leaves•The boy in the classroom needs a pen.•The man standing there is my teacher.定语从句：一个句子充当定语The boy who is reading needs the pen.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。
Ⅰ. 概念：(1) 定语从句：在主从复合句中用作定语的从句叫定语从句。
定语从句一般紧接在先行词后面。
(2) 先行词：被定语从句修饰的成份。
先行词可以为一个词，短语，或整个主句。
(3) 关系词：引导定语从句的词，并代替先行词在从句中担任一定的成分。
分为关系代词和关系副词。
(4) 定语从句基本构成：先行词+关系词+从句A) 关系词的作用：1) 引导定语从句，连接主句和从句，相当于一个连词；2) 必在从句中作某个句子成份（可以做主语，宾语，表语，定语，状语）1.The student who answered the question was John.2. I know the reason why he was so angry.3. The boy (whom) you are talking to is my brother.4. I’d like a room whose window looks out over the sea.B)简单句变定语从句例1：The girl is Mary. The girl is standing there.The girl (who is standing there ) is Mary.如何改写定语从句?1、找准主句和从句，并找出两个简单句的共有成分，确定先行词。
2、将从句中的共有成分去掉。
3.找准关系词，用关系词引导从句剩下的部分，并紧接在被修饰词（先行词）之后。
例2：A plane is a machine. The machine can fly.例3：The girl is Mary. We saw her yesterday.C)定语从句选择关系词三步曲：第一找出先行词；第二看先行词在定语从句中的语法功能（做主语、宾语或状语）；第三选择合适的关系词。
Ⅱ. 几个关系代词的基本用法：●that: 可指人或物；在定语从句中作主语，宾语，表语。
(指人时，相当于who或whom；指物时，相当于which)(一般不用于非限制性定语从句; 不可置于介词后作宾语) 如：1. A letter that/which is written in pencil is difficult to read. (主语)2. Do you know the gentleman that/who spoke just now?3. You can take anything (that) you like. （宾语）4. What is the question (that/which) they are talking about?5. Here is the man ( who/whom/that ) you want to see.●which: 指物；在定语从句中作主语，宾语如：1. The book which/that was on the desk was bought by my father.（主语）2. The book (which/that) I bought yesterday is very interesting.（宾语）3. He was proud, which his brother never was. （表语）●who, whom, whose:who: 主格, 在从句中作主语，在口语或非正式用法中作宾语; 只可指人whom: 宾格，在从句中作宾语; 只可指人whose: 属格，在从句中作定语，可指人也可指物。
I like the students who/that work hard. （主语）All who heard the story were amazed. (代词如he, they, any, those, all, one等后多用who.)He's a man from whom we should learn. （宾语）= He's a man (whom/who/that) we should learn from.A child whose parents are dead is called an orphan.（指人）I'd like a room whose window faces south. （指物）whose +n. =the +n. + of which (物)= ofwhich (物)+ the +n.=I'd like a room of which the window faces south. whose + n. =the +n. + of whom(人)= of whom(人)+ the +n.=I'd like a room the window of which faces south.注意：定语从句中的谓语动词的单复数于先行词保持一致This is one of the best books that have ever been written.He is one of the students who study hard at school.当one前面有the only等限定词和修饰语时, 定语从句的谓语动词要与one保持一致而取单数形式例如This is the only one of the best books that has ever been written.He is the only one of the students who studies hard at school.Ⅲ. 几个易混淆的关系代词的比较:●宜用that, 而不宜用which 的情况.①先行词为不定代词表示物,all, much, something, everything, anything ,nothing, none, the one等,②先行词被only, any, few, little, no, just, very, one of等词修饰时。
③先行词是序数词时或被序数词修饰时。
④先行词是最高级或被最高级修饰时。
.⑤先行词既有人又有物，用which和who都不适合，这时宜用that. 如：⑧主句是There be 结构，修饰其主句的定语从句宜用that 作关系代词. 如：1. There is still a seat in the corner that is still free.⑨被修饰成分为表语时，或者关系代词本身是定语从句的表语时,该关系代词宜用that .2. My home village is no longer the place ( that ) it used to be .●定语从句中宜用which而不宜用that 的情况:①当关系代词的前面有介词时.1.A zoo is a park in which many kinds of animals are kept for exhibition.②在非限制性定语从句中.1.Crusoe's dog, which was are now very old, became ill and died .2.More and more people are beginning to learn English, which is becoming very popular in our country. (which指代主句)(B) who & that:● who 和that 指代人时，有些情况宜用who, 而不宜用that①先行词为anyone, anybody, those, all, one, ones, they, he, people时. 如：.②在There be 结构中，修饰主语的定语从句宜用关系代词who 指代人. 如：1.There is a gentleman who wants to see you .Ⅳ.关系副词引导的定语从句:●When 指时间，在定语从句中作时间状语。
定语从句中when=in/on/at which, 其先行词是表时间的名词（如：time, day, week, tear, month, etc.）I still remember the day when /on which my brother joined the army.（作状语）I shall never forget the day when Shen Zhou Ⅴwas launched, which has a great effect on my life.I still remember the days which/that we spent together. （作宾语）Next winter which/that you'll spend in Harbin, I'm sure, will be exciting.●Where 指地点，在定语从句中作地点状语。
定语从句中where=in/on/at which,其先行词是表示地点的名词，如：place, school, factory, room, etc.This is the factory where /in which he worked last year. （作状语）This is the place where I was born.This is the park which/that they visited last year. （作宾语）I live in the room which was bought by my father.I think you have got to the point where a change is needed, or you would fail.He's got himself into a dangerous situation where he's likely to lose control of the plane.●Why 指原因，在定语从句中作原因状语。
