定语从句Attributive Clause定语从句 Attributive Clause定义：定语从句（Attributive Clause)就是修饰名词或者代词的从句，通常在被修饰词的后面，本质上相当于形容词的作用，被修饰的名词或者代词叫做先行词（Antecedent)。分类：定语从句分为限制性定语从句(Restrictive Attributive Clause)和非限制性定语从句(Non-restrictive Attributive Clause)。限制性定语从句是先行词不可或缺的部分，若去掉则表达不完整。非限制性定语从句是先行词的附加说明，去掉也不影响主句意思，与主句通常用逗号分开。eg:Success will come to him who is honest and diligent. My wife, who is out at the moment, will phone you when she gets back.一.定语从句的引导词1.先行词是人，且在从句中作主语时，用关系代词（Relative Pronoun) who/that;作宾语时，用who/whom/that或者省略。eg:The man who/that lives in that house is my uncle. That is the girl (who/whom/that) I met at the party yesterday.2.先行词是物，用关系代词which/that充当主语和宾语，作宾语时可以省略。which还可以指婴儿、动物、表示单数意义的集合名词、人的身份、地位、职业等。eg:My favorite place is Kunming which/that is called as the Spring City. This is the place (which/that) he would like to visit.3.先行词是人或物，且在从句中作定语时用whose引导，也可以替换为of which(指物)和of whom(指人)。eg:You're the only one whose advice he might listen to. They live in a room whose window opens to the north.人物主语宾语定语主语宾语who/that定语who/whom/that/省略whose/of whomwhich/thatwhich/that/省略whose/of which只用that不用which引导定语从句的特殊情况1.当先行词是all,everything,nothing,something,little,none等不定代词时；2.当先行词被序数词或形容词最高级修饰时；3.当先行词被no,every,some,any,only,very,much等限定词修饰时；4.当先行词既有人又有物时；5.当先行词为主句的表语或关系代词为从句的表语时；6.There be句型中，先行词为物时；7.当先行词前面有who,which,what等特殊代词时。eg:1.He is the only person that I want to see. 2.All that we need is the support from you. 3.Who is the lady that is waiting at the school gate? 4.There is a room in the building that is still free. 5.Our school is no longer the school that it used to be. 6.The first lesson that I learned will never be forgotten. 7.The passengers and parcels that filled the car were mixed.只用which不用that引导定语从句的特殊情况1.which可以引导非限制性定语从句，that不能；2.which之前可以接介词，that不能；3.当先行词本身为that时。eg:1.He changed his mind, which made me very angry.2.The questions are all on art, about which I know nothing.3.What's that which flashed in the sky just now?先行词是时间、地点、原因，且在句中作状语时，分别用关系副词（Relative Adverb)when,where,why引导。when和where可以用介词＋which替换，why的先行词只能是reason，why可以用for＋which替换。eg:1.She remembered the day when(on which) Tom had first walked into her office.2.We then moved to Paris,where(in which) we lived for six years.3.This is the reason why(for which) you should leave.准关系代词as,than,butas,than,but这几个连接词可以像关系词一样，前面有名词作为先行词，但后面的定语从句并不典型。这种词我们称为准关系代词。1.as用在such＋(n.)＋as(和...同样的)； the same＋(n.)＋as(像...这样的) ；the same as(同样的人或事)；such as(这样的东西或人);as...aseg:1.She has as much money as is required. 2. I haven't much money but you can use such as I have. 3.The town is not the same country as it used to be. 2.than作为准关系代词出现在more...than,less...than,fewer...than等结构中，这时than前面要有名词。eg:I have more money than is needed.3.but是具有否定意义的准关系代词，代替人或物，在意义上等同于that/which/who...not，but前面的主句要有另一个否定意义。eg:1.There is no one but in concerned about his future. 2.There is nothing but she can do.二.非限制性定语从句1.非限制性定语从句关系词和限制性定语从句的关系词的区别✬非限制性定语从句中的关系词不可省略；✭whom在非限制性定语从句中作宾语时不可用who代替；✮非限制性定语从句的先行词可以是整个主句，此时用which引导，也可以用in which case,at which point,on which occasion.eg:1.A young man had a new girl friend,whom he wanted to impress.2.The son didn't pass the exam,which disappointed him.2.as和which引导非限制性定语从句的区别❊ which 引导的定语从句只能位于主句后，但as引导的从句可位于主句前、中、后。❊as在定语从句中作主语时，从句谓语通常要有be或别的系动词，但which不受此限制。❊as 引导的定语从句只表示一个众所周知或意料之中的事，但 which 不受此限制。as多用于固定搭配中：as is often the case(这是常有的事)，as was expected(不出所料)，as often happens(正如经常发生的那样)，as is known to all(众所周知)，as has been said before(如上所述)，as is mentioned above(正如上面所提到的)等。eg:1.David, as you know, is a photographer. 2.Tom was late, which made Mr. Zhang very angry. 3.He married her, which was unexpected. 4.As is known to all, anyone who breaks the rules should be punished.Exercise1.
