student who answered the question was my friend.(先行词是student在定语从句中充当主语)The girl you met just now is my sister.(先行词是girl在定语从句中作宾语),2.关系代词、关系副词,引导定语从句的关系代词、关系副词,代替先行词在定语从句中充当成分。,在定语从句中能作主语的关系代词有who,that,which其中who用于指人，which用于指物，that既可指人也可指物。,如:,An architect is a person who/that design houses and buildings.The supermarket which/that was opened last week is a very modern one.,在定语从句中能作宾语的关系代词有who,whom,which,that其中who,whom用于指人which用于指物that既可指人也可指物。,如:The suit which/that the tailor made for me doesnt fit me.The man whom/that I beat in the tennis game was my father.,n,在定语从句中能作定语的关系代词有whose或the+名词+of+which,如:He lives in the room whose door is green.=He lives in the room the door of which is green.The girl whose father is a teacher studies very well.=The girl the father of whom is a teacher studies very well.,在定语从句中作方式状语的关系副词常被省略如:,This is the way(how)he worked out the problem.,n,介词如果在定语从句的句首时,作宾语的关系代词只能用whom,which且不可省略,如:The man with whom you shook hands just now is the head of our department.=The man whom you shook hands with just now is the head of our department.This is the book to which I referred in my talk.=This is the book(which)I referred to in my talk.,n,非限制性定语从句和先行词关系不紧密用逗号和主句分开,另译作一句,作为一种补充说明即使去掉从句，主句的意思仍然清楚而限制性定语从句和先行词关系紧密从句不能去掉,如果去掉意思就不清楚且主句和从句之间无逗号一般译在先行词前面。,n,除that不可以引导非限制性定语从句外其他关系代词和关系副词均可引导非限制性定语从句。,All the books，which have pictures have been sent to them.He has a brother who is a doctor.他有一个当医生的兄弟。（也许不止一个兄弟）He has a brother,who is a doctor.他有个兄弟，他是一个医生。,n,which在所引导的非限制性定语从句，有时可以修饰整个主句即代替主句的意义。,The examination has been put off，which is what we want.考试被推迟了，这正是我们希望的。,Mary was late again,which made her teacher angry.玛丽又迟到了，这使她的老师非常生气。,n,只用which不用that的情况：,（1）引导非限制性定语从句时Bamboo is hollow，which makes it very light（2）当关系代词前有介词时The room in which my family live used to be a garage（3）当先行词本身为that时 ：That which you told him about is what we want to know你告诉他的正是我们想知道的,n,只用that不用which的情况：（1）先行词有序数词或形容词最高级修饰时如:The first place that we visited was the Great Wall.This is the best film that has ever been made.（2）先行词前有only,few,little,right,any,all,one等修饰时 The only furniture(that)he had in the room was a chair and a small desk.There is little time that we can use.(3)先行词是不定代词some,all,anything,little,much,something,everything,nothing,none等时That is all(that)I want to say.Is there anything(that)I can do for you?,(4)先行词为人和物的名词词组They talked about persons and things that they remembered in the school.(5)主句前who,whom有时Who is the man that is reading the newspaper over there?(6)在there be 或there live结构中先行词指物There is a book on the desk that I am very interested in.,(7)先行词指物在主句中作表语,Is this the book that you borrowed in the library?,(8)在 way(指方法)后面常用that代替how或 in which结构,That was the way(that)he did it.,(9)time(表示次数)前有序数词修饰That was the last time that I met her.,.,(10)习惯用法中that 可以用作关系副词代替(in,on,for)which及 when where,why,而且that可省略The way that(in which)you look at problem is wrong.I never forget the day(when,that,on which)I went to school 20years ago.Do you know anywhere(that,where)I can get a drink?I d like to know the reason(that,why,for which)you wont come.,(11)当先行词前有the same修饰时或当先行词和关系代词指同一人或物时This is the same man that/who I told you about.,This is the book that I bought yesterday.,只用who的情况。(1)先行词为those指人 Those who want to go there raise your hands.(2)there be(live)结构中先行词指人There is a young man outside who asks for you.There lived a king who was kind to his people.(3)先行词为指人的不定代词one,anyone,no one,all,nobody,any body,none等Anyone who broke the window would be punished.We should learn from the one who benefits us.,n,选用关系副词不能光看先行词是否是表示时间，地点和原因的名词，而必须分析从句谓语动词与先行词之间的逻辑关系。如果关系词在从句中作主语或宾语则他仍须用关系代词which或that,如：We will never forget the day,which we spent together.I like to take my vacation in the mountain,which is quiet and beautiful.That is the reason,which he gave us for his action.,n,as 引导限制性定语从句时,先行词常用such和same修饰,as在从句中不省略如:,He used such expressions as he could find n the tests.They stayed for the night in the same room as they had once rented.,As 引导非限制性定语从句时,as代表整个主句的意义,定语从句在主句中的位置比较灵活。,如：He is a teacher，as is clear from his manner.Taiwan,as is known to everyone,is a part of China.,n,定语从句修饰of前面的词还是of后面的词,要看of前面的词是否有定冠词修饰。,如:Tom is one of the boys who were late this morning.(汤姆是所有早上迟到的男孩中的一员)Tom is the only one of the boys who was late this morning.(汤姆是所有男孩中早上迟到的唯一个),Exercises:,1.There are 102 elements(化学元素)found in nature,_are metals2.The house _roof was damaged has now been repaired.3.I have never been to Rome but thats the city Id most like to visit.,4.The reason _I have not done my homework is there are too many difficult points.,5.“Gone are the days _I was young,”the seventy-year-old man said.6.This is the place _he lived in his childhood.,7.The pen_he writes id Hero 60.8.Mrs.Lee will move into her new house
