(完整版)定语从句知识点整理及相应练习

一．定语从句：定语从句是一种在句子中起修饰作用的从句，用于修饰一个名词或代词，就像一个形容词一样，让这个名词或代词的信息更加具体。

1. 基本结构---定语从句通常由关系代词（如who, whom, whose, which, that）或关系副词（如when, where, why）引导。

例如：--- The book that/which I bought yesterday is very interesting.（我昨天买的那本书非常有趣。

）其中，“that/which I bought yesterday”是定语从句，修饰先行词“the book”，“that/which”引导词，在从句中作宾语，指代“the book”。

2. 关系代词的用法--- who/whom：用于指人。

“who”在从句中做主语，“whom”作宾语。

---例如：The man who helped me is my teacher.（帮助我的那个人是我的老师。

）这里“who”在从句中做主语，不能省略；而在句子“The boy whom I met yesterday is my friend.”（我昨天遇到的那个男孩是我的朋友。

）中，“whom”作宾语，在口语中也可以用“who”来代替，并且可以省略。

--- whose：表示所属关系，意为“……的”，既可以指人也可以指物。

-例如：I know the girl whose mother is a doctor.（我认识那个女孩，她的妈妈是一名医生。

）“whose mother”在从句中做主语，修饰“the girl”；对于物，“The house whose windows are broken needs to berepaired.”（窗户破了的那所房子需要修理。

）--- which：用于指物，在从句中可以作主语或宾语。

---例如：The movie which we watched last night was really exciting.（我们昨晚看的电影真的很刺激。

10.定语从句定从的本质是形容词，修饰其前的名词或代词。

与名从和状从最大的区别是其前有先行词。

一、定语从句在复合句中，修饰某一名词或代词从句叫定语从句，在句中起定语修饰的作用. 被定语从句修饰的词叫做先行词。

引导定语从句的词叫关系代词或关系副词。

如：Mary is a beautiful girl.Mary is a girl (who is beautiful). 定语从句先行词关系代词This is a book which was written by Tom who is my best friend.I remember the days____ I spent with you.I remember the days____ I played with you.I remember the place____ I visited last year.I remember the place____ I lived last year.I remember the reason____ I give to you.I remember the reason____ I was late.二．引导词注：这些引导词中有名词从句中的What，how，Wh—ever吗？三．引导词各自用法（Ⅰ）1．who修饰“人”作主语，口语中可作宾语。

T his is the man who often helps me.(who作主语)The man who you just talked is a teacher.2．whom修饰“人”作宾语。

可省略，但在介词后和非限制性定语从句中不可省略。

The doctor (who/whom) you are looking for is in the room.3．whose是who，which的所有格，作定语，修饰“人”“物”。

This is a book whose cover is blue.4.that修饰“人”“物”作主语、宾语、表语。

（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。

定语从句知识点,考点,难点,练习题,⾼考真题定语从句⼀、定语从句的⼏个概念1、定语从句：在复合句中修饰名词和代词的从句叫做定语从句。

分为限制性定语从句和⾮限制性定语从句。

2、先⾏词：被定语从句修饰的名词或代词叫做先⾏词。

3、关系词：引导定语从句的词叫关系词。

分为关系代词和关系副词。

4、关系词的作⽤：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关系词的位置：在先⾏词和定语从句之间。

如：The man who is shaking hands with my father is a policeman.该句中, who is shaking hands with my father 是定语从句, the man是先⾏词, who是引导定语从句的关系词, 代替先⾏词the man, 在定语从句中作主语。

All the books that have pictures have been sent to them.所有有插图的书都已经给他们寄去了。

（⾔外之意，没有插图的书，就没有寄去。

）All the books, which have pictures, have been sent to them.所有的书都已经给他们寄去了，所有的书都有插图。

四、“介词+关系代词”引导的定语从句1、含有介词的短语动词⼀般不拆开, 介词仍放在从句中短语动词的后⾯。

如：look for, lookafter, take care of 等。

This is the watch (which / that) I am looking for.2、介词放在关系代词前, 关系代词指⼈时只⽤whom,不可⽤who, that；关系代词指物时只⽤which, 不可⽤that。

关系代词是所有格时,⽤whose。

The man with whom you talked just now is my neighbour.The plane in which we flew to Canada was really comfortable.This is the very man in whose pocket I found my lost money.3、“介词+关系代词”前还可有some, any, none, all, both, neither, many, most, each, few 等代词或者数词。

定语从句知识点总结精讲练习定语从句知识点总结精讲练习1）定语从句的基本概念：定语从句是用来修饰名词或代词的从句，起形容词作用，也称为形容词性从句。

被定语从句修饰的词叫先行词，定语从句一般紧跟先行词。

定语从句一般用关系代词或关系副词引导，关系词在定语从句中充当一个成分，并在含义上替代先行词。

The man is my cousin.He came to see me this morning.替换：The man who came to see me this morning is my cousin.先行词关系代词在定语中做主语，不可省略↖定语从句2）关系词:①关系代词（指人/指物/表所有格）;A.指人的关系代词：who,做主语或宾语；whom，只做宾语；that,做主语或宾语（但指代人称并充当从句主语时，通常用who）He is a student.We should learn from him.替换：He is a student(who,whom,that)we should learn from.关系代词充当从句主语时，不能省略，充当宾语时，可以省略。

B.指物的关系代词：whh,做主语或宾语；that,做主要或宾语；He sent me a present last night.The present is a me watch.替换：The present(whh,that)he sent me last night is a ne watch.关系代词充当从句主语时，不能省略，充当宾语时，可以省略。

C.表所有格的关系代替：指某人的或某物的：whose,做先行词的所有格Is there anyone?Her name is Linda.替换：Is there anyone whose name is Linda?②关系副词（时间/地点/原因）。

A.where指地点，充当地点状语This is the place.We spent our childhood in that place.替换：This is the place(whh/that)we spend our childhood in.This is the place in whh we spent our childhood.This is the place where we spent our childhood.B.when指时间，充当时间状语He‟ll always remember the day.His grandma passed away on that day.替换：He‟ll always remember the day（whh/that）his grandma passed away on.He‟ll always remember the day on whh his grandma passed away.He‟ll always remember the day when his grandma passed away.C.why指原因，充当原因状语This is the reason.They were late for the meeting because of the reason.替换:This is the reason why they were late for the meeting.③准关系代词assuch……as引导定语从句……,so/such……that……如此……以致于……引导结果状语从句the sam e……as(相似物)/that（同一物）……This is the same bag as I lost yesterday.(相似物)This is the same bag that I lost yesterday.（同一物）as……as…….Such people as were mentioned by him were honest.（as在定语从句中做主语）I‟ve never seen such a clever man as he is.（as在定语从句中做表语）I like the same book as you do.（as在定语从句中做宾语）I shall do it in the same way as you did.（as在定语从句中做状语）He is as diligent a man as ever lived.（as在定语从句中做主语）先行词是一句话或一句话的一部分时，关系代词可用whh或as,但whh不能放句首，as可放在句首，句中，句末，有“正如”的意思As is known to all,he is the best student in our class.（as在定语从句中做主语）He came late again,whh made his teacher very angry.3)限定性与非限定性定语从句A）限制性定语从句:是用来限制所修饰对象的意义，不能被拿掉，如果拿掉，余下的部分的意义就会不清楚；The man who spoke at the parents‟meeting just now is John‟s father.B)非限制性定语从句：是对所修饰的词作进一步说明，仅起补充作用，拿掉他，其他部分仍然清楚。

高中英语语法：定语从句定语从句在句中做定语，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。

注意：关系代词和关系副词处在先行词和定语从句之间，起着连接主从句、指代先行词和在从句中作句子成分的三重作用。

一、关系代词that, which, who引导的定语从句二、关系代词whose引导的定语从句关系代词whose为关系代词who的所有格形式，用作名词的限定语，whose引导的定语从句既可为限制性的，也可为非限制性的。

先行词既可为人，也可为物，whose和它所修饰的名词在定语从句中可作主语及动词或介词的宾语。

例如：This is the scientist whose name is known all over the world.The room whose window faces south is mine.He has written a book whose name I’ve forgotten.=He has written a book the name of which I’ve forgotten.四、判断关系代词与关系副词先把主句和定语从句分开，再找出定语从句所修饰的名词/代词（即先行词），然后放入定语从句中，看看这两者的搭配情况。

1）如果定语从句和该先行词可以直接相连，且在从句中充当主语/宾语/表语的话，则用关系代词。

This is the city (which/that) you visited last year.2）如果定语从句和该先行词无法直接相连，必须另外多加上介词，并在定语从句中充当状语时，则使用关系副词。

This is the city where you stayed last year.选择：1. Is this museum ___ you visited a few days age?A. whereB. thatC. on whichD. the one2. Is this the museum ____ the exhibition was held.A. whereB. thatC. on whichD. the one五、限制性和非限制性定语从句1）定语从句有限制性和非限制性两种。

三大从句——定语从句句子的成分定语从句，在一个复合句中作定语修饰某一个名词或代词，因此被称作定语从句；又因作定语的往往是形容词，所以定语从句又称形容词性从句。

定语从句是指一类由关系词引导的从句，往往位于被它修饰的词或词组之后。

被定语从句修饰的词或词组称作“先行词”，引导定语从句的词称作“关系词”，“关系词”又分为“关系代词”和“关系副词”。

·关系代词：that which who whom whose as·关系副词：when where why从句结构：从句是一个将关系词提前到句首的陈述句，即将关系词还原后变为一个完整的陈述句。

定语从句又分为“限制性定语从句”和“非限制性定语从句”，限制性定语从句起限定作用，修饰特定的名词或代词；而非限制性定语从句只起到补充说明某种信息的作用。

·限制性定语从句：从语义上看，限制性定语从句主要起限定作用，只能修饰名词或代词，如果删去限制性定语从句，整个句子表意会不完整甚至不通顺；从结构上看，限制性定语从句往往紧跟先行词，并且一般不用逗号隔开。

·非限制性定语从句：从语义上看，非限制性定语从句主要起补充说明的作用，可以修饰名词、代词、短语或句子，在句子中不充当成分，缺少也不会影响全句的理解。

从结构上看，它与主句之间往往用逗号隔开；若将非限制性定语从句放在句中，其前后都需要用逗号分隔。

做题技巧：·判断句子是否为复合句（长难句分析课时内容）·判断从句是否充当定语，若是则下一步；否则判断是否为剩下两种从句·判断先行词是人还是物，抑或整个句子·确定先行词在从句中所作的成分·确定关系词，从句缺成分选关系代词（没有what！）；反之选关系副词（没有how！）·关系代词关系代词所修饰的先行词在从句中充当的成分that人/物主语/宾语/表语which物/句子主语/宾语/表语who人主语/宾语/表语whom人宾语whose人/物定语（先行词的所有格）as人/物/句子主语/宾语/表语·关系副词关系副词所修饰的先行词在从句中充当的成分when时间时间状语where地点/抽象地点地点状语why reason原因状语注意事项（考点）：·只能用that的情况（先行词具有唯一性，绝对性）①当先行词被形容词最高级或序数词所修饰，或先行词本身是形容词最高级或序数词时，只能用that②当先行词是指物的不定代词或被这些词所修饰时，只能用that③当先行词被the only,the very（正是，恰恰）,the last,the same等含“唯一”意义的词修饰时，只能用that④当主句是以which,who引导的特殊疑问句或强调句型时，能用that时，为避免重复只能用that⑤当主句是there be或here be结构，且定语从句修饰指物的主语时，只能用that⑥当先行词既含有人也含有物时，只能用that⑦在双重限制性定语从句中，如果一个从句用who或者which引导时，为避免重复，另一个从句只能用that引导⑧当先行词指物且为主句的表语或关系代词是从句的表语时，常用that而不用which·只能用which的情况①当先行词指物且关系代词在从句中作介词的宾语，且介词在关系代词前时，只能用which，当介词和从句中的谓语构成固定的动词短语（如look after,look for,look forward to,take care of等）时，一般不能将其拆分开提前。

初中英语定语从句全部详解和专项练习其实在初中英语中让许多人头疼的就是定语从句了。

下面是初中三年的定语从句所有及其练习。

定语从句在句中做定语，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，在从句中作主语和宾语。

例如：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。

定语从句知识要点及练习定语从句知识要点及练习（⼀）定语从句在句中起定语作⽤，修饰某⼀名词或代词。

定语从句所修饰的词叫先⾏词，定语从句放在先关系代词的作⽤：1) 连接作⽤(引导定语从句，连接从句和主句)2) 替代作⽤(在从句中替代前⾯的先⾏词或整个句⼦)3) 成分作⽤(在从句中必须要担任⼀个成分)I.关系代词在定语从句中的具体⽤法1. who指⼈, 在从句中作主语(或宾语)．The girl who took you to my place is my friend.2.whom指⼈, 在从句中作宾语．The young men whom/who he employs are always complaining about their long hours．3.whose表⽰所属关系, 指⼈或指物, 在从句中作定语．The film is about a spy whose wife betrays him．4.that指⼈或指物, 在从句中作主语或宾语．All the apples that fall down are eaten by the pigs．The young lady that wears a blue blouse is a singer．5.which指物, 在从句中作主语或宾语．The stairs which lead to the language lab are rather slippery．II.限制性和⾮限制性定语从句根据定语从句与先⾏词的关系是否紧密, 可分为限制性定语从句和⾮限制性定语从句。

限制性定语从句往往紧跟在先⾏词后，不使⽤逗号分开, 翻译成中⽂时, ⼀般把定语从句翻译在被修饰词(即先⾏词) 前⾯。

⽽⾮限制性定语从句，⼀般使⽤逗号隔开,可把定语从句翻译在被修饰词(即先⾏词) 前⾯, 也可以翻译在其后, 作为附加说明．有时, 对两者的理解还会产⽣歧义。
