定语从句一、定义及相关术语1、定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般跟在它所修饰的先行词之后。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。2、先行词：被定语从句修饰的词叫先行词。3、关系词：引导定语从句的词叫关系词。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； 关系副词有when, where, why等。关系词通常有下列三个作用：A、引导定语从句；B、代替先行词；C、在定语从句中担当一个成分4. 定语从句分为限制性定语从句和非限制性定语从句: 限制性定语从句对先行词起限制、确定的作用，是先行词不可缺少的定语，如果省去，主句的意思就会不完整或不合逻辑。这种定语从句和主句之间不能用逗号隔开。 非限制性定语从句和先行词关系松散，只是对先行词作附加说明，如果省去，主句的意思仍然完整或清楚.从句和主句之间须用逗号隔开。关系词指代充当成分关系代词that人或物主（宾）which物主（宾）who人主（宾）whom人宾语whose+n人或物定语Eg. I know the man who/that wear a hat. (连接主从句，替代先行词the man,在定从中做主语)III. 定语从句解题三步骤：1.找出先行词2.判断成分：确定先行词在从句中的成分（主语，宾语，状语）3.选择正确的关系词注意：准确判断先行词在定语从句中的成分.请找出下面句子中的定语从句,并判断其成分：（1） I met Mary who looked very sad.（2） The old man whom you talked to yesterday is my uncle.（3） This is the pen which he gave me.二、关系代词引导的定语从句1、who 指人，在定语从句中作主语,宾语，做宾语时常可省略。The boys who are playing football are from Class One. 2、whom 指人，为who的宾格，在定语从句中做宾语，常可省略。关系代词whom 在口语中可用who或that代替。The man ( whom / who )you met just now is my old friend.3、which 指物，在定语从句中做主语或宾语，做宾语时常可省略。Football is a game which is liked by most boys. This is the pen ( which ) he bought yesterday. 4、that 既可指人也可指物，指人时，相当于who 或whom；指物时，相当于which.。在定语从句中作主语或宾语，做宾语时常可省略。The number of people that / who come to visit this city each year reaches one million. The person that /whom you introduced to me is very kind. The season that / which comes after spring is summer. 5、Whose 通常指人，也可指物，在定语从句中做定语。I visited a scientist whose name is known all over the country. He has a friend whose father is a doctor. 【注意】指物时，常用下列结构来代替：the+n.+of+ whichThe classroom whose door is broken will soon be repaired.= The classroom the door of which is broken will soon be repaired.Do you like the book whose cover is yellow?= Do you like the book the cover of which is yellow? 注：that与which 用法区别(1)只用which, 不用that的情况 (a) 在引导非限定性定语从句时,只能用which。 (错)The tree, that is four hundred years old, Is very famous here. (b) 介词后用which, 不能用that。（物用which，人用whom). We depend on the land from which we get our food. We depend on the land that/which we get our food from. 1.在非限制定语从句中。3.有两个定语从句，其中一个从句关系代词已用了that，另一个宜用which. This is the paper that I read every day and which I find so interesting.4.当先行词本身是that. The predicate is that which is said of the subject. (2) 只能用that作为定语从句的关系代词的情况 (a) 在there be 句型中，只用that，不用which。 (b) 在不定代词，如：anything, nothing, the one, all, little, few, much等作先行词时，只用that，不用which。 (c) 先行词有the only, the very, the same, the last, just修饰时，只用that。 (d) 先行词为序数词、数词、形容词最高级时，只用that,不能用which。. (e) 先行词既有人，又有物时。 (f) 先行词指物，在主句中作表语时 Eg; Is this the book that you borrowed in the library? Who that break the window should be punished All that is needed is a supply of oil. Finally, the thief handed everything that he had stolen to the police. 三 只用who的情况当先行词是those, she ,he ,they,one,ones,anyone等代词时，关系代词用who.He who knows others is learned, and he who knows himself is wise. 6. 五、关系代词as和which 引导的定语从句as 和which 引导非限制性定语从句时， 其用法有相同之处，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宾语，代表前面整个句子。He married her, as / which was natural. He is honest, as / which we can see. 2、as 引导的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分割主句。 which 引导的非限制性定语从句只可放在主句之后。另外，as 常常有“正如、正像”的含义。As is known to all, China is a developing country. He is from the south, as we can know from his accent. Zhang Hua has been to Paris more than ten times, which I dont believe. 【注意】 当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。Tom was late for school again and again, which made his teacher very angry. These tables are made of metal, which made them very heavy. 当先行词受such, the same 修饰时，关系词常用as。He is not such a fool as he looks. This is the same dictionary as I lost last week. 二、关系副词引导的定语从句1、when 指时间，在定语从句中作时间状语。 I still remember the day when I first came to this school The time when we got together finally arrived. 2、where 指地点，在定语从句中作地点状语。Shanghai is the city where I was born. The house where I lived ten years ago has been pulled down. 注：当先行词是case， point, stage, situation等表示状况，阶段，某方面的词时也要用where3、why 指原因，在定语从句中作原因状语。Please tell me the reason why you missed the plane. The reason why he was punished is unknown to us. 【注意】关系副词引导的定语从句经常可以用“介词+关系代词”引导的定语从句来表示。关系副词=介词+关系代词 why=for which 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)Great changes are taking place in the city where / in which they live.The reason why / for which he refused the invitation is quite clear. 三、“介词+关系代词”引导的定语从句关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。The school (which / that) he once studied in is very famous.= The school in which he once studied is very famous. Tomorrow I'll bring here the magazine (which / that) you asked for.= Tomorrow Ill bring here the magazine for which you asked.This is the boy (whom / who / that) I played tennis with yesterday.= This is the boy with whom I played tennis with yesterday. 【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 等。This is the watch (which / that) I am looking for. (正) This is the watch for which I am looking . (误)The babies (whom / who / that) the nurse is looking after are very healthy. (正)The babies after whom the nurse is looking are very healthy. （误）2、若介词放在关系代词前，关系代词指人时只可用whom，不可用who和that；关系代词指物时只可用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. (正) The man with that / who you talked just now is my neighbour. (误)The plane in which we flew to Canada was really comfortable. (正)The plane in that we flew to Canada was really comfortable. (误)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。He loves 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. 四、关系代词与关系副词的选择 用关系代词还是关系副词引导定语从句主要看关系词在定语从句中的作用（即所担当的成分）。试比较：I know a place where we can have a picnic. D20×1年12月31日股东权益总额为5 925万元I know a place which / that is famous for its beautiful natural scenery.I will never forget the days when we spent our holidays together.B620万元 I will never forget the days that / which we spent together.A血液凝固性增高 D血液凝固性先降低后增高课堂训练A.开发周期大大缩短B.降低了系统开发中的风险一、单项选择1、Stephen Hawking believes that earth is unlikely to be the only planet life has developed gradually. 1DIC是一种常见的疾病。( )A. thatB. whereC. whichD. whose 2、I've become good friends with several of the students in my school I met in the English speech contest last year. 答案 E A. who B. where C. when D. which1DIC时血液凝固功能异常表现为3、The girl arranged to have piano lessons at the training centre with her sister _ she would stay for an hour.
