.高中定语从句详细讲解一: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。定语从句一般紧跟在它所修饰的先行词之后。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。例如：Themanwhoisshakinghandswithmyfatherisapoliceman.该句中，whoisshakinghandswithmyfather是定语从句，修饰先行词theman，“who”是引导定语从句的关系词，代替先行词theman，在定语从句中作主语。二:限制性定语从句和非限制性定语从句限制性定语从句 形式上：不用逗号“，”与主句隔开。意义上：是先行词不可缺少的定语，如删除，主句则失去意义或意思表达不完整。译法上：译成先行词的定语：“的”关系词的使用上：A作宾语时可省略 B可用that C可用who代替whom非限制性定语从句形式上：用逗号“，”与主句隔开。意义上：只是对先行词的补充说明，如删除，主句仍能表达完整的意思。译法上：通常译成主句的并列句。关系词的使用上：A不可省略 B不用that C不可用who代替whom限制性定语从句举例：TheteachertoldmethatTomwastheonlypersonthatIcoulddependon.老师告诉我说汤姆是我唯一的可以依靠的人。非限制性定语从句举例：Hismother,wholoveshimverymuch,isstrictwithhim.他妈妈十分地爱他，对他要求很严格。三:关系代词引导的定语从句1who指人，在定语从句中作主语。TheboyswhoareplayingfootballarefromClassOne.正在踢足球的男孩是一班的。Thatistheteacherwhoteachesusphysics. 那就是教我们物理的老师。2whom指人，在定语从句中做宾语，常可省略。MrLiuistheperson(whom)youtalkedaboutonthebus.刘先生就是你们在公共汽车上谈论的那个人。LiMingisjusttheboy(whom)Iwanttosee.李明正是我想要见的男孩。 3Which指物，在定语从句中做主语或宾语，做宾语时常可省略。Footballisagamewhichislikedbymostboys.足球是大多数男孩所喜欢的运动。Thefactorywhichmakescomputersisfarawayfromhere.制造计算机的那家公司离这儿很远。4That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，作宾语时常可省略。 Whereisthemanthat/whomIsawthismorning?我今天早上看到的那个人在哪儿？Thepersonthat/whomyouintroducedtomeisverykind.你介绍给我的那个人很友好。5Whose通常指人，也可指物，在定语从句中做定语。Hehasafriendwhosefatherisadoctor.他有一个爸爸当医生的朋友。Ioncelivedinthehousewhoseroofhasfallenin.我曾经住在那幢屋顶已经倒塌了的房子里。注意：指物时，常用下列结构来代替：Theclassroomwhosedoorisbrokenwillsoonberepaired.Theclassroomthedoorofwhichisbrokenwillsoonberepaired.Doyoulikethebookwhosecoverisyellow? Doyoulikethebookthecoverofwhichisyellow?6 as 的用法:(as 引导定语从句, 在定语从句中作主语、宾语、表语)如为限制性的，多用于the same as ; the same as；such as ; as many/much as；so as等结构中。I have the same book as you (have). 我有一本和你的一样的书。 .-Why didnt you mention that in face of the police just now?- I thought it was such a minor detail as was hardly worth mentioning. 比较：Here is so big a stone as no one can lift. （定语从句） Here is so big a stone that no one can lift it.（结果状语从句）如为非限制性的，多单独引导一个定语从句，表示说话人对话语的看法态度解释或评论.这种定语从句可置于句首，句中或句尾，译为正如，这一点。（动词常为know, see, expect, point out, etc.）As we all know, smoking is harmful to ones health . (as 作宾语)Smoking is harmful to ones health , as we all know .（as 作宾语）Smoking, as we all know, is harmful to one health.He was a foreigner, as I knew from his accent. (宾语, 先行词是前面整个句子)注意:the same.as与the same that的区分当先行词被the same修饰时关系词既可以用as,也可以用that在表示事物时,有时两者有一定的区别.一般说来,表示同一种类多用as,表示同一事物多用that.在抽象概念上,同种类事物是没有绝对区别的,所以两个词可以换用.例如This is the same book that I used yesterday. This is the same book as I used yesterday.四:“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。Theschool(which/that)heoncestudiedinisveryfamous.Theschoolinwhichheoncestudiedisveryfamous.他曾经就读过的学校很出名。注意：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。lookfor,lookafter,takecareof等。Thisisthewatch(which/that)Iamlookingfor.(正)这是我正在找的手表。ThisisthewatchforwhichIamlooking.(误)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,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。Themanwithwhomyoutalkedjustnowismyneighbour.(正)你刚才跟他谈话的那个人是我的邻居。Themanwiththat/whoyoutalkedjustnowismyneighbour.(误)“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。如：Heloveshisparentsdeeply,bothofwhomareverykindtohim.他深深地爱着他的父母，他们俩待他都很好。Inthebaskettherearequitemanyapples,someofwhichhavegonebad.篮子里有好些苹果，有些已经坏了。五:关系副词引导的定语从句1when指时间，在定语从句中作时间状语。IstillrememberthedaywhenIfirstcametothisschool.我仍然记得我第一次来到这所学校的那一天。Thetimewhenwegottogetherfinallyarrived.我们团聚的时刻终于到了。2where指地点，在定语从句中作地点状语。ShanghaiisthecitywhereIwasborn.上海是我出生的城市。Ivisitedthefarmwherealotofcowswereraised.我参观了那个饲养了许多奶牛的农场。当现行词为point, case, age, business, degree condition occasion,situation,atmosphere, scenes等时,在定语从句作状语时,用where.例如, )1 I can think of many cases_students obviously knew a lot of English words and expressions but couldnt write a good essay. A. why B. which C. as D. where 2 Many people who had seen the film were afraid to go to the forest when they remembered the scenes_people were eaten by the tiger.

Whats that which flashed in the sky just now?八:宜用who不用that的情况在限制性定语从句中，当先行词指人时，关系词可用who(m)或that，二者常可互换。 但在下列情况中，用who(m)，而不用that： (1) 当先行词是one, ones, any, few, anyone, anybody, someone, somebody, everyone, everybody等词时。如： Is there anyone who can answer this question?
