名词从句与定语从句的区别及解题技巧
名词从句与定语从句的区别及解题技巧 蔡湛艺 摘要：由于名词从句与定语从句的部分引导词相同的缘故，很多学生容易把两者混淆。其实，我们可以从从句的功能和所处的位置、同位语从句和定语从句的区别、句意决定从句的属性等三种途径区分它们。确定从句的属性后，我们可以从名词从句中的所缺成分及定语从句的先行词等角度确定从句的关系引导词。本文还附有近十年的高考真题演练。 关键词：名词从句，定语从句，引导词 由于名词从句与定语从句的部分引导词相同的缘故，很多学生容易把两者混淆。其实，我们可以从以下三种途径区分它们。 一、由两种从句的功能和所处的位置进行区别。 名词从句的主要功能是充当句中的主语、宾语、同位语和表语，它们的位置一般处于句首、动词或介词之后；而定语从句的功能是起修饰和限定先行词的作用，一般处于名词、代词或名词短语之后。如： 1.Whether we will go picnicking depends on the weather. （位于句首，为主语从句） 2.I learned that he was a famous writer. （位于谓语动词后，为宾语从句） 3.He is satisfied with what you’ve done. （位于介词后，为宾语从句） 4.That is why I came here. (位于系动词后，为表语从句) 5.I will never forget the days when we got together. （在名词day后，为定语从句） 6.This is the book that I have been looking for. （在名词book后，为定语从句） 7.The reason why he came home late is that he was trapped in the traffic jam. （前句 在名词reason后，为定语从句；后句在be动词后，为表语从句） 二、同位语从句和定语从句的区别。 有些表示“看法、问题、事实、消息”等名词如thought, idea, belief, question, doubt, problem, fact, news, information, order, hope, answer, conclusion等后面既可以接同位语从句，也可以接定语从句。区别的办法要看这些词在从句中有没充当什么成分。如： The idea that we invited him yesterday is quite good. （idea在从句中没充当任何成分，that 在此无词义，引导的从句属同位语从句） The idea that he thought of is quite good.（idea在从句中是of的宾语，that指代the idea，引导的从句是定语从句，修饰限定先行词the idea.）
定语从句 知识讲解 “介词+关系代词”的用法
介词+关系词怎么用？介词加关系词分别等于什么？ 答：一、“介词＋关系代词”的用法 当关系代词在定语从句中作介词宾语时，我们通常用“介词＋关系代词”引导定语从句。如果指“人”，用“介词＋whom”；如果指“物”，用“介词＋which”。例如： Do you know the lady with whom our manager is talking in the office? Where is the supermarket in which you bought the laptop last week? ●使用“介词＋关系代词”要注意以下几点： (一)选用介词的依据： (1) 根据定语从句中谓语动词的搭配习惯(即固定短语)。例如： Yesterday we visited the West Lake for which Hangzhou is famous. (2) 根据先行词的搭配习惯(约定俗成，不一定是短语)。例如： The old woman with whom you talked just now is a famous artist. (3) 根据句子的意思来选择。例如： The naughty boy made a hole in the wall through which he could see what is happening outside. (4) 表示“所有”关系或“整体中的一部分”时，通常用介词of。例如： I have about 20 books, half of which were written by Bing Xin, the famous writer. (二)在定语从句中，含介词的短语动词不可拆开使用(短语拆开后含义发生变化)，如look after, look for等。例如： The babies whom the nurses are looking after are very healthy.(正) The babies after whom the nurses are looking are very healthy.(误) (三)“of which / whom”有时可以用“whose＋名词”结构来改写。例如： The building whose roof was damaged in the earthquake has been repaired.
“介词+关系代词”引导的定语从句
“介词+关系代词”引导的定语从句 请同学们先看下面的高考题： 1. Human facial expressions differ from those of animals in the degree ______ they can be controlled on purpose. A. with which B. to which C. of which D. for which 2. Last month, part of Southeast Asia was struck by floods, from ______ effects the people are still suffering. A. that B. whose C. those D. what 3. I saw a woman running toward me in the dark. Before I could recognize who she was, she had run back in the direction ______ she had come. A. of which B. by which C. in which D. from which 4. Last week, only two people came to look at the house, ______ wanted to buy it. A. none of them B. both of them C. none of whom D. neither of whom 【点拨】 ●“介词＋关系代词”既可以引导限制性定语从句，也可以引导非限制性定语从句。在此结构中，关系代词指人时用whom，不可用who或that；指物时用which，不能用that；关系代词是所有格时用whose。但如果介词后置，则不受这种限制，关系代词还可以省去，尤其在口语中。如： 1) Do you know the girl to whom our teacher was talking? = Do you know the girl (that/who/whom) our teacher was talking to? 2) The school (that/which) my brother once studied in is very famous. = The school in which my brother once studied is very famous. 2.关系副词when，where，why可用“介词＋which”来代替。关系副词实际上是介词＋先行词。其中 when=表时间的介词（如：in，at,on,during等）+which； Where=表地点的介词（如：in，at,on,under等）+which； Why=表原因的介词（如：for）+which (1)当先行词表示时间，定语从句中缺少时间状语时，通常用关系副词when引导，此时也可选用表示时间的介词＋which来代替关系副词when。 I still remember the day when I came here. ( on the day =when) (2)当先行词表示地点，定语从句中缺少地点状语时，通常用关系副词where引导，此时也可选用表示地点的介词＋which来代替关系副词where。 This is the house where I lived last year. ( in the house= where) (3)当先行词为reason，定语从句中缺少表示原因状语时，通常用关系副词why引导，此时也可以用for which来代替关系副词why。 There are many reasons why people like traveling. (for the reasons =why) 注意： 1. 含有介词的短语动词一般不拆开, 介词仍放在短语动词的后面。如: look for, look after, take care of， pay attention to, look forward to 等。
三 介词提前的定语从句
三介词提前的定语从句（介词+关系代词+……） 1 关系代词which, whom在定语从句中作介词的宾语时，从句可有：介词+ which\whom 引出。如： 1）Great changes are taking place in the city which they live in . Great changes are taking place in the city in which they live. 2) The film which I’m speaking of is to be shown next week. The film of which I’m speaking is to be shown next week. 3. This is the teacher whom I’ve learnt a lot from. This is the teacher from whom I’ve learnt a lot. 4. The man whom we sent the present to is a doctor of laws. The man whom to whom we sent the present is a doctor of laws. 5. The situation which we had got into was very dangerous. The situation into which we had got was very dangerous. 6 The policeman whom Mr Henry is talking with is a friend of mine. The police man with whom Mr Henry is talking is a friend of mine. 定语从句之关系副词 一关系副词引导的定语从句 1.When 表示时间，其先行词往往是表示时间的名词（如time, day , hour, year 等）。在从句中做时间状语。 I will always remember the day . I got the first prize on the day . I will always remember the day when I got the first prize . 2. where 表示地点，在定语从句中做地点状语。其先行词往往是表示地点的名词（如place, room, house, street, area等） This is the place. My mother was born in the place. This is the place where my mother was born . This is the room . I lived in the room last year. This is the room where I lived last year. This is the village. My father worked there 3years ago. This is the village where my father worked 3years ago. 3 why 引导定语从句，在从句中表示原因，做原因状语。其先行词一般为reason. I don’t know the reason why she looks unhappy today.我不知道为什么她今天看上去不高兴 The reason why he said that is quite clear. 他为什么那样说的理由是十分清楚的。 二当堂训练 1 用关系副词when, where 把下列每对句子连接成定语从句。 1）I’ll never forget the day. I joined the PLA on that day. _________________________________________________. 2) Last autumn my sister went to the town. She was born there. _____________________________________________________. 3) The days are gone. During those days we used ‘foreign oil.” ___________________________________________. 4) Li Fang lives in that street. Do you know the street? ______________________________________________________? 二如何判断关系代词与关系副词
定语从句中介词加关系代词的用法
“介词+关系词”的用法 1、关系代词在从句中作介词的宾语时，介词常可以提前，但介词提前时，关系代词只能用which 或whom。 如：The school (that/which) he once studied in is very famous. →The school in which he once studied is very famous. Tomorrow I will bring here a magazine (that/which) you asked for. →Tomorrow I will bring here a magazine for which you asked. We'll go to hear the famous singer (whom/that/who) we have often talked about. →We'll go to hear the famous singer about whom we have often talked. 2、关系副词when, where, why 和介词+which之间的关系。 关系副词when, where, why可以用适当的介词+which来替代。介词的位置非常灵活，有时放在关系代词之前，有时放在动词之后。如：when=in/on/at…+which, where=in/on/at…+which, why=for+which 如：I won’t forget the date when( on which) I was born. This is the room where (in which) I lived. = This is the room which I lived in. I don’t know the reason why (for which) he hasn’t come today. Tom still remembers the days when (in which) they lived in Tianjin. 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 如：This is the watch which/that I am looking for. (√)This is the watch for which I am looking. (F) 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 如：The man with whom you talked is my friend. (√)The man who/that you talked with is my friend. (F) The plane in which we flew to Canada is very comfortable. (√) The plane in that we flew 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等代词或者数词如：He loved his parents deeply, both of whom are very kind to him. In the basket there are quite many apples, some of which have gone bad. There are forty students in our class in all, most of whom are from big cities. 4). 把握“介词＋关系代词”结构中介词的选用 介词的选择与主句中先行词的搭配密切相关。
定语从句介词加关系词
“介词+ which / whom ”引导的定语从句 1. 介词+关系代词”引导的定语从句，是定语从句一种介词前置的定语从句句型，介词 与关系代词之间存在一种介宾关系。当关系代词在定语从句中作介词宾语时，把介词置于关系代词前，即演变出介词+关系代词”句型。 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；关系畐U词有 where, when, why 等。 3. whose通常指人，也可指物，在定语从句中做定语 (1) He has a friend whose father is a doctor. (2) I once lived in a house whose roof has fallen in. (3) The classroom whose door is broken will soon be repaired. 一、基本构成 1. 介词+关系代词”结构引导的定语从句中，关系 代词只能用which (指物)或 whom(指人)，即：介词 +which/whom 。 (1)The man to whom you spoke is a teacher. (2)The city in which she lives is far away. (3)The little girl is reading a book ,in which there are many cartoons. 注意：当介词放在关系代词的前面时，用在介词后的关系代词不能省略。 2. 在定语从句中，当介词置于定语从句的谓语动词之后时，可用that/which(指物); that/who/whom (指人)作介词的宾语.且此处关系代词可以省略。如： (1)The man (who/whom /that ) you spoke to is a teacher. (2)The city (which/that ) she lives in is far away. 注:通常介词放在定语从句中动词后，也可以放在关系代词前面，但有些特殊动词短语搭 配不能拆分，介词只能放在动词后，女口： look for, look after, pay atte ntion to ,take care of , look forward to, liste n to 等。 This is the pen (that / which) you are look ing for. The patient ( who/whom /that ) she is looking after is her father. The words( that /which) we should pay attention to are written on the blackboard. There are fifty patients (who/whom/that )we must take good care of. 练习： Are these sentences right?
介词+关系词引导的定语从句
介词+关系代词”引导的定语从句 介词加关系代词引导的定语从句要注意以下几点： 1．“介词+ 关系代词”引导的定语从句时，介词的宾语只能用which（指物）和whom （指人），即：介词+which/whom。不能用that 和who。 .This is the teacher from whom we’ve learned a lot. 这就是从他那里我们学了很多东西的老师。 Great changes have taken place in the city in which we live. 我们所居住的城市发生了巨大的变化。 2．有时介词也可放在从句的末尾，这时关系代词可用which/that(指物)， who/whom/that（指人），也可以省略。 . The situation (which/that ) we had got into was very dangerous. 我们当时的处境很危险。 The man (whom/who/that) you were talking to just now is my English teacher. 你刚刚和他谈话的那个人是我的英语老师。 3．当定语从句中的谓语动词短语是固定搭配，不可分割时，那么动词短语中的介词不能前置。 .This is the pen which I’m looking for. 这是我正在找的那支钢笔。 不能写成：This is the pen for which I’m looking. 4．定语从句也可由“名词/代词/数词+介词+which/whom”引出。 . That old man has two sons, one of whom is a doctor. 那个老人有两个儿子，其中一个是医生。 The house, the windows of which ( = whose windows = of which the windows) were damaged, has now been repaired. 窗子遭破坏的那栋房子现在已经修好了。 5．引导定语从句的关系副词(when, where, why) 可以用“介词+关系代词”代替。 .I’ll never forget the day when I joined the party.

定语从句(关系副词+介词+which whom)学生版
定语从句（学生版） 关系副词when, where, why 介词+whom/which引导的定语从句 一、基本概念 1. 定语从句除可用关系代词引导外，还可用关系副词_______, _______与_______来引导。 2. 它们的区别是：when用于指________，相当于in/ at/ on/ during which, where用于指 ________，相当于in/ at/ from which, why用于指________, 相当于for which。 3. 关系副词在定语从句中代替_______作_____语，_____省略，有时可以用________代替。 二、基本用法 1. 关系副词when关系副词和where的先行词是表示时间(如the day(s), the time, the year等)和地点(如the place, the house, the factory, the station等)的一类词，而关系副词why的先行词通常只是for the reason(s)。另外，________和________可引导限制性和非限制性定语从句，而________则只用于引导限制性定语从句，不用于引导非限制性定语从句。 ★用适当的关系副词填空 ①I will remember the day ______ I left my hometown forever. (作________状语= ________) ②This is the place ________ he works. (作________状语= ________________) ③He told me the reason ________ he was late again. (作________状语= ________________) 2. 注意不要以为在时间名词后就一定用关系副词when,在地点名词后就一定用关系副词 where,在表示原因的the reason后就一定用关系副词why。到底选用关系副词还是关系代词,关键是看它们在定语从句中是用作状语(用关系_______)还是用作主语或宾语(用关系_______)。英语中的关系副词主要是when, where, why三个。不要想当然地将how 用作关系副词修饰the way。如不说This is the way how he spoke，可改为This is how he spoke(how引导的是表语从句)，当然也可说成This is the way______________ he spoke. ★用适当的关系副词或关系代词填空 ①Don’t forget the time ________I’ve told you. 不要忘记我告诉你的时间。 ②I’ll never forget the days_______ I worked with you. 我永远不会忘记我与你共事的日子。 ③He works in a factory ________makes radio parts. 他在一家造无线电零件的工厂工作。 ④He works in the factory ________ his father worked. 他在他父亲工作过的那家工厂工作。 ⑤That’s the reason ________he explained to us. 那就是他向我们解释的理由。 ⑥That’s the reason ________she left home. 那就是她离家出走的原因。 3. 介词+关系代词的用法
定语从句解释练习及答案
定语从句 ●关系词的意义及作用 定语从句是中学阶段英语语法中十分重要的一个语法项目。它在句子中出现的频率很高。对正确理解句子的意义起着举足轻重的作用。定语从句分为：限制性定语从句和非限制性定语从句。定语从句一般都紧跟在它所修饰名词后面，所以如果在名词或代词后面出现一个从句，根据它与前面名词或代词的逻辑关系来判断是否是定语从句。 被定语从句所修饰的名词或代词叫做“先行词”。引导定语从句的词叫“关系词”。关系词有两个作用：1、引导定语从句。2、代替先行词在其引导的定语从句中充当一定的句子成分。 理解和牢记这两条概念，弄清楚关系词在定语从句充当什么成分，是掌握定语从句的关键。 ●关系词的选用与判断 一. 关系词在定语从句中所充当的成分 正确选择关系词是掌握定语从句的关键。关系词的选择完全取决于先行词在定语从句中所充当的成分。关系词一共有九个，它们在从句中所充当的句子成分见下表。 关系词主语宾语表语定语状语替代 that √√√××人/物; which √√×××物 who √√√××人 whom ×√×××人 whose ×××√×人/物 when ××××√时间 where ××××√地点 why ××××√原因 as √√√××人/物 二、关系词的选用 1.指物时只用that不用which引导定语从句的场合： 1）当先行词是不定代词时：(all,much,little, none,the one, something, anything,everything.nothing等) Is there anything that you want to explain? You should hand in all that you have. 2)先行词前有形容词最高级、序数词或only,very, none, no, little, any, all, few, much等修饰时. This is the first step that can be taken.
介词 关系词引导的定语从句
介词+关系代词引导的定语从句 【知识点1】 直接位于介词之后的关系代词只能是which或whom，构成介词+which（指物）；介词+whom （指人）两种结构。 【例】The man to whom you talk just now is a famous runner. 【例】The service about which the students complain a lot should be improved. 【例】He is a library assistant from whom I borrowed some books. 【例】It is a famous school from which he graduated 3 years ago. 【例】The chair on which he is sitting now is made of wood. 【知识点2】 直接位于介词后面的关系代词不能省略，但如果将介词移于句子末尾而不位于关系代词之前时，可省。 【例】The man (who/that/whom) you talk to just now is a famous runner. 【例】The service (which/that) the students complain about a lot should be improved. 【例】He is a library assistant (whom/that/who) I borrowed some books from. 【例】It is a famous school (which/that) he graduated from 3 years ago. 【例】The chair (which/that) he is sitting on now is made of wood. 【知识点3】 关系副词when, where, why 可以相应地转化为：介词+which结构。 【例】This is the house where I lived two years ago. =This is the house in which I lived two years ago. 【例】Do you remember the day when you joined our club? =Do you remember the day on which you joined our club? 【例】I don’t know the reason why he said so. =I don’t know the reason for which he said so. 【知识点4】 有一些动词短语中的介词是固定搭配，不可以拆开，一般还是放在动语之后，不提前： 【例】He is the student (who/whom/that) the teachers are looking for. 【例】The number of the children (who/whom/that) she takes care of is 30. 【知识点5】 注意复杂介词短语+which或whom引导的定语从句，是高考考查热点。 【例】They finally climbed up the mountain, on top of which many strange birds were seen. 【例】Look at the photo. This is Mr. Green, in front of whom sit three students. 【知识点6】 不定代词+of+ which/ whom 引导的定语从句可化为of+ which/ whom+ 不定代词结构；这也是高考常考点。其中用到的不定代词有some, any, none, both, all, many, a few, few, a little, little, either, neither, one, 等等。 【例】There are 40 students in our class, most of whom（=of whom most）like English.
介词引导的定语从句 -答案
介词+关系代词引导的定语从句 “介词+关系代词”引导的定语从句是定语从句的一种复杂形式，这类定语从句的关系代词主要有which ,whom , whose , 它们既可以引导限定性定语从句，也可以引导非限定性定语从句。关系代词前该选用什么样的介词，要根据不同的语境、习语、惯用法等来决定。一．介词选择的主要标准 1.介词与定语从句的先行词是一种习惯性搭配 Human facial expressions differ from those animals in the degree to which they can be controlled on purpose.人类的面部表情和动物的面部表情就可控制的程度来说是不一样的。( to a degree ) The English play in which my students acted at the New Year’s party was a great success.那场在新年晚会上我学生参加表演的英语剧很成功。( in the play ) The schools themselves admit that not all children will be successful in the jobs for which they are being trained.学校本身承认，并不是所有的孩子都能在他们所接受的培训的职业成功。( be trained for the job ) 2.介词与定语从句中的动词是一种习惯性搭配 Who is the man with whom our teacher is shaking hands? 我们的老师与之握手的那个男士是谁？( shake hands with sb. ) Last month , part of Southeast Asia was struck by floods , from whose effects the people are still suffering. 上个月，东南亚的部分地区发生洪水，人们还在遭受着洪水所带来的影响。(suffer from sth. ) 3.介词与定语从句中的形容词构成一种习惯性的搭配 Ours is a beautiful country , of which we are greatly proud . 我们的国家是一个美丽的国家，我们为之感到很自豪。( be proud of ) The woman to whom Spielberg is married is an actress. 同斯皮尔伯格结婚的女人是一位演员。( be married to ) The woman to whom he was engaged was a doctor. 他与之订婚的那个女士是位医生。(be engaged to ) 4.有时关系代词前用什么介词，要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 I was a woman running toward me in the dark. Before I could recognize who she was, she had run back in the dark.Before I could recognize who she was , she had ran back in the direction from which she had come.看见一位妇女在黑暗中像我走来，我还没来得及认清她是谁，她已经从她来的方向跑回去了。（如果仅注意先行词，很容易受习惯心里的影响而使用in this direction 的搭配，但考虑到语境后的come ，则应该使用from。） He was educated at the local high school, after which he went on to Beijing University. 他在当地一所高中上学，之后他上了北京大学。（after which 的意思就是“在当地一所高中接受完教育之后”）。 In the office I never seem to have time until after 5:30 pm. by which time many have got home.在 办公室我好像总是没时间，只有等到下午五点半，而那个时候大家都已经回家了。（此句不能受at 5:30 pm 的通常表达的影响而选用介词at, 而应该依据整个句子的语意来确定介词。）5.表示“所有格”或“整体与部分关系”时，用介词of The journey around the world took the old sailor nine months, of which the sailing time was 226 days.这次环球旅行老水手用了9个月，其中航行的时间是226天。 The factory produces half a million pairs of shoes every year, 80% of which are sold abroad. 这个工厂每年生产50万双鞋，其中的（指50万双鞋）80%销往海外。 I was told that there were about 50 foreign students studying Chinese in the school, most of whom
带介词的定语从句解释
介词+which/whom 引导的定语从句 1．在“介词+which/whom”结构中，关系代词用which 还是用whom ，取决于它前面的先行词是物还是人。先行词是物，用which ；若为人，就用whom 。 如： (1)Nearby were two ships in which they had come to the island. (2)I can’t remember the name of the person to whom I gave the money. 2．这一结构用什么介词取决于先行词的意义和定语从句中谓语动词结构及“介词+which/whom”在句中的作用。 (3)This is the room in which we lived last year. (4)There were three people from whom we attempted to find out information. 3．因为含有介词的短语动词一般不拆开，介词仍放在动词的后面。此种情况下关系代词可用which, that , who, whom ，或将他们省略。 (5)Is this the book (which/that ) she was looking for? (6)The babies (whom /who/that) the nurse are looking after are very healthy. 4．表示地点、时间和原因含义的“介词+which”结构可分别用关系副词where, when 和why 替换。 (7)The earth on which /where we live is a planet. (8)I’ll never forget the day on which /when I joined the Lea gue. (9)Is there any reason for which /why you should have a holiday? 5．Of which可以代替whose 用来指物，其词序一般为“名词+ of which” (10)They live in a house whose door/the door of which opens to the north. (11)He has written a book whose name /the name of which I’ve completely forgotten. 6．“复杂介词 in front of, at the back of , on the top of, in the middle of 等+ which”结构可引导非限制性定语从句。 (12)He works in a factory, in front of which there is a river. (13)In the evening we arrived at a hill, at the foot of which there was a temple. 7．“介词+which/ whom”结构中的which 和 whom 不能替换为that，因为that 不能做介词宾语。如果用that ，介词必须反复到从句有关动词的后面
