2、whose, which, that)和关系副词(when, where, why) 关系词都充当从句的某个成分，它所替代的相应成分应省去。在定语从句中，当who, which, that作主语时，谓语的单复数应与先行词保持一致。关系词常有3个作用：引导定语从句。代替先行词。在定语从句中担当一个成分。定语从句分为限制性定语从句和非限制性定语从句。非限制性定语从句与先行词的关系不如限制性定语从句与先行词的关系紧密，没有它，主句的意思也清楚，因此用逗号隔开。关系词在非限制性定语从句中的用法与在限制性定语从句中的用法基本一样。一关系代词以及基本用法关系代词指示对象作用例句That人.物主.（宾）Th

3、e student that answered the question was John.回答问题的学生是约翰。The book （that） you lent me was interesting.你借给我的那本书很有趣。Which物主.（宾）Football is a game which is liked by most boys. 足球是大多数男孩都喜欢的游戏.This is the pen (which) he bought yesterday. 这是他昨天刚买的钢笔.Who人主.（宾）A doctor is a person who looks after peoples hea

5、2）that前不能有介词。3）某些在从句中充当时间，地点或原因状语的介词+关系词结构可以同关系副词when where和 why互换。where = in/at + whichwhen=in/on/at/during + which why = for whichwhose=of which/whom+the+物/人=the+物/人+of which/whom例如：1.

7、es absent from the meeting for is not clear.=The reason for which /why hes absent from the meeting is not clear. 4） whom在定语从句中只指人，做宾语，可用who或that代替，也可以省略但后边的介词提前时，只用whom例如：Do you know the man (whom/who/that) the teacher is talking to?= Do you know the man to whom the teacher is talking?She is the per

9、as引导定语从句, 如：as.as；so.as；such.as；the same+ 名词+as。You can buy as many books as you want in this bookstore. (as作want的宾语)Such computers as are used in our office are made in South Korea.(as作定语从句的主语) This jewel is the same one as I showed you the other day. (as作showed的直接宾语)This jewel is the same one that

10、 I showed you the other day.(that作showed的直接宾语）请注意“the same + 名词 + as”与“the same + 名词 + that”的区别。 (1) She wore the same dress that she wore at Marys wedding. 她穿着她在MARY婚礼上穿过的一条裙子。(2) She wore the same dress as her young sister wore. 她穿着和她妹妹所穿的一样的裙子。注意：定语从句suchas 与结果状语从句such that的区别：as在所引导的定语从句中作主语，宾语；

11、that在结果状语从句中不做成分(3)He has such a good laptop as I want to buy.(4)He has such a good laptop that I want to buy one.7). 先行词有比较级修饰时用than；先行词有否定词修饰时用but，表示双重否定，此时的but = who/which/that.not.My mother always gives me more money than is needed.(than作定语从句主语)This year, the farmers have harvested more grain th

12、an was expected. (than作定语从句主语)There is not a student but wants to go to university.=There is not a student who/that doesnt want to go to university.(but作定语从句主语)练习选择正确的关系代词填入题目中的空白处。(that which who whose whom )1.Do you see the bridge-was built last year2. The nurse _ we talked about can speak English

13、 well.3. The old gentleman _ you met just now is a famous writer.4. The girl to _ I lent my bike works in a hospital.5. She was the brave girl _ name is known to everybody.注意二：that和which虽然都能指物，但是在某些情况下，只能用that指物而不用which1） 先行词被形容词最高级修饰时，例如：This is the most interesting movie that I have ever seen.（作宾语

14、可省略）This is the most beautiful park that we have visited.2）先行词被the very，the only the same, the last等修饰时，例如：This is the very book that Im looking for.（作宾语，可省略）The only thing that she could do was to wait patiently.（作宾语，可省略）3）先行词被序数词修饰时，例如：The first thing that we do in the morning is to clean the clas

15、sroom.（作宾语，可省略）This is the third largest city that was founded in the 1980s.（作主语）4）当先行词是anything, everything, nothing (something 除外), few, all, none, little, some等代词时，或者是由every, any, all, some, no, little, few, much，each等修饰时.Have you taken down everything (that) Mr. Li has said?There seems to be not

16、hing (that) seems impossible for him in the world.All that can be done has been done.There is little (that) I can do for you.5）当先行词前面有who, which等疑问代词时Who is the man that is standing there?Which is the T-shirt that fits me most?6)、当先行词既有人，也有动物或者物体时Can you remember the scientist and his theory that we

17、 have learned?7）先行词是主句的表语或关系代词在从句中作表语，例如：He is not the boy that he used to be.China is no longer the country that it used to be.8).当在there be句型中，通常情况下用that，不用which、注意三： 宜用which而不用that的情况1. 在非限制性定语从句中。Bamboo is hollow, which makes it light.2. 在关系词前有介词时。This is the room in which Chairman Mao once live

18、d.3. 当先行词本身是that时。The clock is that which can tell us the time.二关系副词：关系副词指示对象作用例句When时间状语Ill never forget the days when I worked together with youThe time when we got together finally came.Where地点状语This is the mountain village where I stayed last year.The house where I lived ten years ago has been p

19、ulled downShanghai is the city where I was born.Why原因状语(1) Please tell me the reason why you missed the plane.(2) I dont know the reason why he looks unhappy today.关系副词（在句中作状语）关系副词=介词+关系代词why=for which（先行词一般是reason）Where=in/ at/ on/ . which (介词同先行词搭配)When=during/ on/ in/ . which (介词同先行词搭配) 某些在从句中充当时

20、间，地点或原因状语的介词+关系词结构可以同关系副词when ,where和why 互换。where = in/at + whichwhen=in/on/at/during + which why = for whichwhose=of which/whom+the+物/人=the+物/人+of which/whom例如：1. This is the house in which I lived two years ago. 这是我两年前住过的房子。=This is the house where I lived two years ago.2. Do you remember the day

21、on which you joined our club？ 还记得你加入我们俱乐部的那一天吗？=Do you remember the day when you joined our club？3. This is the reason why he came late.=This is the reason for which he came late.注意：1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等T This is the watch which/that I am looking for. (T正确)F This

22、is the watch for which I am looking. (F错误)2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose(1) The man with whom you talked is my friend. (T)The man with that you talked is my friend. (F)(2) The plane in which we flew to Canada is very comfortable. (T)The plane in that we fle

23、w in to Canada is very comfortable. (F)3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) He loved his parents deeply, both of whom are very kind to him.(2) In the basket there are quite many apples, some of which have gone bad.(3) There are forty students in our class in

24、all, most of whom are from big cities.4. the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。The way in which/ that/省略he answered the question was surprising.判断改错 This is the mountain village where I visited last year. I will never forget the days when I spent in the countryside. This is the mountain villa

25、ge (which) I visited last year.Ill never forget the days (which) I spent in the countryside.习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。 方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1. Is this museum _ you visited a few days ago?A. whereB. thatC. on whichD. the one例2. Is this the museum

26、_ the exhibition was held?A. whereB. thatC. on whichD. the one答案：例1 D，例2 A例1变为肯定句： This museum is _ you visited a few days ago.例2变为肯定句： This is the museum _ the exhibition was held. 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1.主句间用逗号隔开，将从句拿掉后其他部分仍可成立 Her house, which was built a hundred years ago, stoo

27、d still in the earthquake. (那座房子在地震中依然耸立，它是一百多年前建造的。)2.在非限定性定语从句中，不能用that，而用who, whom代表人，用which代表事物,when where why 分别代表时间 ,地点,原因(做状语)3. as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：1)、As和which都可以在定语从句中做主语或者宾语，代表前面整个句子。Which还可指代主句中的某个词或短语。(1) He married her, as/which was natural.(2) He was honest, as/which w

28、e can see.2)、as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后，意为“这，这一点”。as有“正如，正像”的意思(1) As is known to all, China is a developing country.(2) He is from the south, as we can see from his accent.(3) John, as you know, is a famous writer.(4) He has been to Paris more than several time

29、s, which I dont believe.难点透析定语从句是高中阶段的重点语法项目之一。因此，有必要全面弄清其用法。定语从句从句型上讲，它与六种句式相似，十分容易混淆。为了分清定语从句与这六种句型的差异，现将其分类例析如下。 【难点一】定语从句与并列句 用一个恰当的词完成下列句子，使之完整、正确Mr Li has three daughters，none of _ is an engineer Mr Li has three daughters，but none of _ is a dancer Mr Li has three daughters；_ are doctors解析：定语从句

30、与并列句的主要区别在于：并列句有像and，but，so等并列连词或两个句子用分号连接，这时就不能再用引导定语从句的关系词了。从结构上看:小题是定语从句，故填whom；小题有并列连词but，是并列句，故填代词 them；小题是两个并列分句，无需连接词，缺少主语，故填none或they。 【难点二】定语从句与地点状语从句 用一个恰当的词完成下列句子，使之完整、正确。 Rice doesnt grow well _ there is not enough water I still remember the farm _ my parents worked ten years ago解析：定语从句与

31、地点状语从句的主要区别在于：定语从句有表示地点的先行词，而地点状语从句则没有；定语从句的关系词根据需要可用“介词which”来代替where，而地点状语从句则通常只能由 where引导。因此，从结构上看:小题无表示地点的先行词，故为表示地点的状语从句，填where；小题中the farm是先行词，是定语从句，故填where，此处的 where可用on which替换。 【难点三】定语从句与强调句 用一个恰当的词完成下列句子，使之完整、正确It is on the morning of May 1st _I met Liang Wei at the airport It is the facto

32、ry _ Mr Wang works 解析：定语从句与强调句的主要区别在于：强调句的结构为“It iswas被强调部分that从句”。被强调部分可以是除谓语以外的任何成分，当被强调部分是人时，还可用who代替that。这一句型中，一定不能因为被强调部分是表时间或地点的词就用when或where代 替 that。从结构上看，小题是强调句，故填 that。此种情况检测的标准是：先把强调句中的It iswas.that去掉，再把被强调部分还原，在不增加或减少任何单词的情况下，如句子仍然成立则为强调句，否则为定语从句。可将第小题改为：I met Liang Wei on the morning of

33、May 1st at the airport显然，这句话是正确的，故为强调句。小题则是定语从句，用上述方法转换便知the factory前缺少个介词in，故填 where。 【难点四】定语从句与结果状语从句 用一个恰当的词完成下列句子，使之完整、正确I have the same computer _ you have She is such a kind and funny girl _ all of us like to make friends with her解析：定语从句与结果状语从句的主要区别在于（这里只讨论the same.asthat和such.as/that两种情况）：在这两

34、种情况下，如果asthat既引导从句，同时又在从句中充当一定的成分，则asthat引导的是定语从句。在the sameasthat结构中，用as指一样的，但不是同一个事物；用that指同一物品，故小题填as；如果asthat在从句中不作任何成分，只起连接作用，则asthat引导的是结果状语从句，故小题填that。 【难点五】定语从句与单句 用一个恰当的词完成下列句子，使之完整、正确 The mother told the lazy boy to work，_ didnt help The mother told the lazy boy to work_ didnt help解析：含有定语从句

35、的复合句与两个单句的主要区别在于：前者有主句，有从句，必须有关系词；而后者则是两个单独的句子，不需要任何关联词。小题两个句子用逗号连接且没有并列连词，显然应是主从句关系，因此需用关系词 which，前面整个句子作先行词；小题则填It，代替前面的整个句子。解题时，注意标点符号的运用。高中英语定语从句句型总结一、疑问句中考查定语从句1. Is this the farm _ you visited last week？A. whereB. the oneC. on whichD. /【解析】答案是D。命题人经常利用疑问句的特殊结构来干扰学生的正确选择。遇到这类定语从句时，最好的办法是先把疑问句还原

36、成陈述句，然后判断谁是先行词，再看关系词在定语从句中所充当的成分，最后确定正确答案。二、倒装句中考查定语从句2. We came to a place， _ stood a big tower.A. whichB. thatC. /D. where【解析】正确答案是D。为了保持句子平衡，句子用了倒装语序。倒装的使用使定语从句的结构变得较为特殊，因此对于使用倒装语序的定语从句，应先把倒装语序还原成正常语序，这样句子结构就比较清晰了。三、 拆分词组和固定搭配3. The second is connected with the use _ the body makes of food.A. of

37、whichB. whereC. to doD. that4. Why cant you realize the part _ they have played in our life？A. whichB. on whichC. whenD. where【解析】正确答案分别是D和A。一些词组和搭配被拆开后，句子的含义就变得难以理解。首先把拆开的词组复原是理解此类定语从句的关键。上述句子中包含以下词组：make use of， play a part （in）。四、添加插入语或状语5. The scientist has made another discovery， _ I believe is

38、 of great importance.A. thatB. /C. whichD. why【解析】应选择C。这类句子主要利用插入语或状语的添加来增加试题的难度。常见的插入语有：I think （suppose， expect， believe， imagine）， in my opinion， to tell you the truth等。做这类题目时，最佳的办法是先删去插入语或状语，这样句子的主干部分就一目了然了。五、插入非谓语动词6. Is this the man _ you want to have _the radio for me？A. who；repairedB. that；repairedC. whom；repairingD. that；repair【解析】D项正确。非谓语动词是英语中难度较大的语法项目之一，因而在定语从句中加入非谓语动词就成了学生最易失分的题目。对付这类题目最有效的办法就是将句子还原。如：我们可以把几个句子中的定语从句进行还原，还原后的句子应是：You want to have the man repair the radio for me.专心-专注-专业
