专题04 定语从句  定义I. 定语从句起形容词的作用，在句中修饰一个名词或代词。被修饰的词叫做先行词，引导定语从句的词叫关系词，他的作用一是放在先行词与定语从句中间起了连接作用，二是在从句中担当一个成分，并与先行词保持数的一致。关系词先行词从句成分例句备注关系代词who人主语Do you know the man who is talking with your mother?whom, which和that在从句中做宾语时，常可以省略，但介词提前时后面关系代词不能省略，也不可以用thatwhom人宾语Mr. Smith is the person with whom I am workingThe boy (whom) she loved died in the war..whose人，物定语I like those books whose topics are about history.The boy whose father works abroad is my desk mate. that人，物主语宾语A plane is a machine that can fly.She is the pop star (that) I want to see very much.which物主语宾语The book (which) I gave you was worth $10.The picture which was about the accident was terrible.as人，物主语宾语He is such a person as is respected by all of us.This is the same pen as I lost yesterday. as做宾语一般不省略关系副词when时间时间状语I will never forget the day when we met there.可用on whichwhere地点地点状语This is the house where I was born.可用in whichwhy原因原因状语I can’t imagine the reason why he turned down my offer.可用for which Ⅱ. as与which的区别：定语从句区别例句限制性定语从句　中名词前有such和the same修饰时，关系代词用as,不能用whichHe is not such a fool as he looks.Don’t read such books as you can’t understand. 非限制性定语从句中as和which都可以指代前面整个主句。如果有“正如，象”的含义，并可以放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。They won the game, as we had expected.They won the game, which we hadn’t expected.As is well known, he is a famous film star in the 1980s. Ⅲ. 限制性定语从句与非限制性定语从句的区别：类别语法意义及特征例句限制性定语从句对先行词起修饰限制作用，如果去掉，主句意思就不完整明确，这种从句与主句的关系十分密切，写时不用逗号分开。The accident happened at the time when I left.非限制性定语从句　对先行词作附加的说明，与主句的关系不十分密切，较松散。从句和主句之间用逗号分开，相当于一个插入语，不能用that引导，关系代词做宾语时也不能省略。His mother, whom he loved deeply, died ten years ago. 一、考点聚焦1、功能：相当于形容词，修饰名词或代词，在句中作定语2、位置：定语从句置于被修饰词之后 Those who are willing to attend the party, sign here please.3、先行词：被定语从句修饰的词称为先行词（1）先行词一般是名词和不定代词，如:some-, any-, every-和no与-boy, -thing的合成词；或all、none、any、some、that、those等代词。数词也可以作先行词，人称代词也同样可作先行词。（2）先行词与关系词是等量关系。必须注意两点： ①先行词在从句中作主语时，从句谓语动词的数由先行词而定。 This is the place which is worth visiting. ②关系词在从句句子中充当了成分，其意思就是先行词的意义，所以在从句中不能重复其意。There are many places we can visit（them）in China.4、关系词：引导定语从句的都称关系词关系代词：who, whom, which, that, whose, as。关系副词：when, where, why。that偶尔也作关系副词。5、确定关系词的步骤（1）先找关系词，看先行词指的是什么。（2）看关系词在从句中所充当的成分。6、在定语从句中，当先行词指物时，下列情况的关系词宜用that而不用which（1）先行词被①形容词最高级 ②序数词 ③数词 ④only、any、few、little、no、all、one of等修饰时。（2）先行词为all、much、little、none、few、one、something、anything等不定代词时。（3）先行词中既有人又有物时。  He was looking pleasantly at te children and parcels that filled his bus.（4）先行词在主句中作表语关系词在从句中作表语时。 The village is no longer the one that was 5 years ago.（5）当主句中含有疑问词which时。  Which are the books that you bought for me ?7、宜用which而不用that的情况 （1）在非限制性定语从句中     （2）在关系词前有介词时 （3）当先行词本身是that时     （4）当关系词离先行词较远时8、关系词who与that指人时，也有不同情况分别用不同的关系词（1）当主句是there be句型时，关系词用who。（2）先行词是为anyone、those、someone、everyone、one等词时，关系词用who。（3）当主句是who作疑问词时，关系词用that。 Who is that girl that is standing by the window?（4）whom在从句中只作宾语，可被who取代。 9、whose作关系词既指人又指物，在从句中作定语。如： Do you know Mr. Smith whose story is very moving? There is a room, whose window faces the river. There is a room, the window of which faces the river. 10、关系代词as,在从句中作主语、宾语和表语。 （1）先行词被such和the same修饰，或句型as many（much）中，从句都用as 引导。 Such books as you bought are useful.     The school is just the same as it was 10 years age. 注意：区别①such … that … 引导的结果状语从句。They are such　lovely children that we love them much　.②the same … that … 引导定语从句。I want to use the same tool that you used just now.（2）无先行词的定语从句用as和which引导。区别：①意义上：as 含有“这点正如……一样”。②位置上：as 从句可置句首，也可在另处。He didn’t pass the exam, as we had expected.There is lots of air in loose snow, which can keep the cold out.As is known, the earth is round, not flat.11、关系副词when与where、why、thatwhen 指时间 = in / at / on / during whichwhere指地点 = in / at / from / whichwhy指原因 = for which当先行词为way、day、reason、time时，可用that作关系副词。（非正式场合）I don’t like the way that / in which / he talks. 当time作先行词时，关系词可以省掉。 This is the first time I have given you a lesson in French. 12、必须注意的问题 （1）关系词作主语时，从句中谓语的数。 （2）注意区别定语从句与强调句。 ①定语从句中关系词作从句成分，复合句。 ②强调it无意义，that / who不是引导词。 ③强调it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。 It is the museum that / which we visited last year.(定语从句) It was in the hotel that we stayed last night.（强调句） （3）定语从句与同位语从句的区别。 ①定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。 ②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。 Word came that their army was defeated.(同位语) We expressed to them our wish that was the same as their.(定语) （4）关系词在从句中省略的情况。 ①关系词作宾语，前无介词时。 ②关系词作表语。 （5）限制性定语从句与非限制性定语从句的翻译。 （6）关系词前有介词或复杂介词，关系词只能是which和whom。 （7）几个特殊的定语从句句型：①He is the only one of the students who has got very good marks in the match.（句中one为先行词） He is one of the students who have got good marks in the match.（句中students为先行词） ②Is this place the one (that) we visited yesterday？ Is this the place (that / which) we visited yesterday?  ③He stood at the window, from where he could see what was happening.④It may rain, in which case the match will be put off.二、精典名题导解 1. The film brought the hours back to me _________ I was taken good care of in that faraway village.（NMET 2001） A. until          B. that          C. when           D. where 解析：答案为C。本题考查分隔定语从句的关系词的选择。作好本题的关键是要能辨认出该定语从句的先行词the hours和关系词被介词短语to me所分隔。定语从句的先行词是表时间的名词hours, 并且关系词在从句中用作状语，故应选择表示时间的关系副词when。 2. ___________ is known to everybody, the noon travels around the earth once every month.(NMET  2001) A. It            B. As             C. That            D. What 解析：答案为B。本题考查as引导的非限制定语从句。as作“正如……”解时，引导的非限制性定语从句来修饰整个句子。当as在从句中作主语时，常用于下列短语：as is known、as is said、as is reported、as is announced等。要注意掌握作关系代词引导定语从句的用法。 3. After living in Pairs for fifty years he returned to the small town ______ he grew up as a child.(NMET  1996) A. which         B. where         C. that            D. when  解析：答案为B。本题考查限制性定语从句中关系词的选择。定语从句的先行词是表示地点的名词短语the small town, 且关系词不作定语从句中的主语和宾语而作地点状语，因此定语从句必须用关系副词where引导。要注意分清先行词在从句中充当的成分，然后选择适当的关系词。  1．（2022·天津市双菱中学高三阶段练习）This term our school offers many optional courses for the students, _______ appeals to many students.A．each of whom B．all of whomC．each of which D．all of which2．（2022·天津市嘉诚中学高三阶段练习）People sit uncomfortably on plastic chairs, looking through old magazines,________have been read hundreds of times previously.A．all of them B．each of which C．all of which D．each of them3．（2022·黑龙江·哈尔滨三中高三阶段练习）Mr. Lin, without ________ we wouldn’t have succeeded, deserves to be crowned as the VIP of our team.A．what B．whom C．which D．whose4．（2022·天津市新华中学模拟预测）Bungee Jumping is very popular among young adults, ________ courage matters more than strength.A．whose B．that C．where D．of which5．（2022·天津市双菱中学高三阶段练习）The sushi bar, the walls of ________ painted navy blue, is indeed an ideal place for us office workers, especially after work.A．whose B．which C．what D．it6．（2022·天津市新华中学高三阶段练习）He was driving so fast as to get himself into a dangerous situation _______ he is likely to lose the control over his car.A．which B．that C．where D．when7．（2022·天津市嘉诚中学高三阶段练习）________is often the case all over the world with new areas of economic activity, the sharing economy is developing faster than existing regulations.A．As B．That C．It D．Which8．（2022·天津市第五十五中学高三期中）These terraces were built by the local Zhuang and Yao people,        Guangxi is home.A．for which B．for whom C．to which D．to whom9．（2022·天津一中高三阶段练习）The book discusses the extent ________ family life has changed over the past 50 years.A．where B．in which C．to which D．that10．（2022·江西·贵溪市实验中学高三开学考试）You can’t wake a person ________ is pretending to be asleep.A．who B．which C．he D．不填11．（2022·北京·高三）Above the trees are the hills, ________magnificence the river faithfully reflects on the surface.A．where B．of whose C．whose D．which12．（2022·天津市咸水沽第一中学三模）________ all his friends say, he is usually warm-hearted, loving and generous.A．Which B．As C．What D．That13．（2022·天津·耀华中学模拟预测）Europe has achieved more in controlling the AIDS virus than Asia in the past ten years, ________ the number of people infected with the virus is going up sharply.A．when B．where C．whose D．that14．（2022·天津市滨海新区塘沽第一中学高三阶段练习）Polluted air does much harm to us, long-time exposure to________can affect our abilities in two areas: language and mathematics.A．it B．that C．which D．what15．（2022·天津·耀华中学高三阶段练习）Green Equator Coffee is grown on the Green Equator Estate(庄园),________coffee is 100% organic and sells at a very low price.A．where B．whose C．when D．which16．（2022·黑龙江·哈尔滨三中高三阶段练习）China will allow all couples to have three children, ________, in my opinion, is helpful to cope with the increasingly aging society.A．that B．which C．what D．who17．（2022·广东·深圳中学高三开学考试）It was in this old farm house ________ his grandfather built 50 years ago ________ he was born and bred.A．where; when B．which; that C．that; which D．where; which18．（2022·陕西·西北工业大学附属中学高三阶段练习）I have sent her several letters, ________ she hasn’t replied so far, so I decide to write her again.A．with which B．in which C．to which D．on which19．（2022·天津河北·二模）There is no month in the whole year ________ nature wears a more beautiful appearance than in the month of August.A．where B．what C．when D．that20．（2022·天津·大港一中高三阶段练习）We live in an age ______ more information is available with greater ease than ever before.A．where B．when C．which D．that
