22、which I have made several friends.Last week,I visited Shanghai,where I have made several friends.上周我参观了上海，在那儿我叫上几个朋友。I will remember the day forever on which I won the first place in the contest.I will remember the day forever when I won the first place in the contest.我将永远记住我在竞赛中获得第一名的那一天。,关系代词前介词的确

23、定,1.根据从句中动词与先行词的逻辑关系，请体会：e.g.Is that the newspaper for which you often write articles?2.根据从句中动词或形容词的习惯搭配，如：e.g.Can you explain to me how to use these idioms about which Im sure.3.根据先行词与介词的搭配习惯，请体会：e.g.1949 was the year in which the P.R.C.was founded.,关系代词前介词的确定,4.非限制性定语从句中，要表示先行词的一部分时，可用“数词/代词+of+关系

24、代词”的结构，如：e.g.There are 50 students in our class,two-thirds of whom have been to Beijing.,关系代词前的介词的确定,5.Whose从句可转换为“of+关系代词”型，如：e.g.They live in a house,whose door opens to the south.,They lived in a house,of which the door opens to the south.They lived in a house,the door of which open to the south.

25、,http:/,考点四：as 和which 引导非限制性定语从句的区别,which引导的从句只能放在主句之后；as引导的从句，可放在句首、句中或句尾。which既可代指先行词，又可代指整个主句的内容。相当于“and this”或“and that”.译为“这一点”。as只能代指整个主句的内容。常带有“正如”之意，且已形成固定结构:as is known,as is reported,as is said,as is expected,as we know,etc.,1.Einstein,as is known,is a famous scientist.2.As is reported,Chi

26、na has become an important country in the world.3.Taiwan belongs to China,as is known to all.4.Bamboo is hollow,which makes it very light.5.He didnt come to attend the meeting,as is expected.,3.as在从句中作主语，从句中的谓语必须 是系动词；而which则不一定。He is very strict,as is shown in his work.4.先行词前有the same,such限定时，关 系词只

27、能用as.I have the same opinion as you(have).Dont read such books as are beyond your ability.,当先行词受the same 修饰时，有时也用 that引导定语从句，但与as引导的定语从句意思有区别。She wore the same dress as her younger sister wore.She wore the same dress that she wore at Marys wedding.,同一类,同一件,5.主从句之间存在逻辑上的因果关系时，关系词往往用which。Tom was late

28、 for school again and again,which made his teacher very angry.,两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。1.关系代词引导的定语从句居句首时。e.g.As we all know,the earth is round.2.当与such或the same连用时，一般用as。e.g.Such books as you tell me are interesting.I have the same plan as you.,Go on Please!,3.当从句和主句语义一致时，用as，反之则用which。e.g.S

29、he has married again,as was expected.She has married again,which was unexpected.,Go on please!,4.as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。e.g.She has been late again,as was expected.Tom has made great progress,which made us happy.,考点五：定语从句的限制性与非限制性,1.结构不同2.功

30、能不同3.先行词不同4.关系词的使用不同5.翻译时的表达方法不同,使用要点,1.关系代词在从句中作主语时，不能省略。e.g.The classroom that is on the fourth floor is poorly equipped.,2.关系代词在从句中作宾语且前面没有介词时，常可省略。e.g.This is the girl with whom he works.,3.关系副词在定语从句中不可省略。e.g.I have come to explain the reason why I was absent from the meeting.,4.只用that，不用which的情

31、况：当先行词有序数词或形容词最高级修饰时；当先行词前有the only,the very,the last等词修饰时；当先行词为anything,nothing,something,everything,all,little,much等不定代词修饰时；当先行词前有all,every,no,some,any,little,much,few等词修饰时；It is 句型中的引导定语从句时。当先行词在定语从句中作表语时。,5.只用which，不用that的情况：引导非限制性定语从句时；引导词前有介词时；一个句子中若有两个定语从句，一个用that引导，另一个用which引导；e.g.He bought

32、a book that could give him much knowledge and which could help him to kill the time.6.当those作为先行词指人时，通常只能用who引导；,as 从句的先行词是the same,such,或被他们所修饰；多用于表示肯定意义的从句中，不用于表否定意义的从句中。e.g.Many of the sports are the same as they were when they started.The result was not such as he expected.It was raining hard,wh

33、ich(as)was unexpected.8.介词+关系代词要根据谓语动词的固定搭配 e.g.This is the evidence with which the case is connected.先行词 e.g.Ill never forget the day on whichwhen I joined the party.,c.句子表达的意思 e.g.The boss in whose department Mr King worked got sacked.d.在非限制性定语从句中，名词代词+of+whichwhom表示整体与部分的关系e.g.The workers,some of

34、 whom stayed for four years,came from different countries.e.介词的位置一般放在关系代词之前，有时也可放在从句中原来的位置上。e.g.We did it in the same way in which he didwhich he did in.,9.That 作为关联词可以当作关系副词用e.g.This is the house in which Louis XIII lived.This is the house that Louis XIII lived.This is the house where Louis XIII lived.This is house which Louis XIII lived in.This is the house Louis XIII lived in.,定语从句的使用需注意：,My brother who is very clever studies chemistry all by himself.使用定语从句勿滥！可以使用单个形容词，或较短的非谓语动词结构的，尽量使用简略些的方式。使句子读起来更顺口！,
