剖析定语从句十大误区
主讲:英语特级教师 王玉峰
定语从句在高中教材各个版本均中被列为重点语法,对于贯穿高中英语始终的定语从句,有的考生还是屡做屡错,究其原因是因为没有认真总结。及时纠错是很好的学习方式,正如在2012年北京高考英语试卷的单选题的23题所说的那样:“One learns a language by making mistakes and correcting them.”,即“一个人学会一种语言是通过出错,然后改正错误学得的”。
本课件设计根据学生作业反馈并结合高考英语试题总结出十类典型错误,所给的例句也可以看出这些错误类型正是各地高考试题命题干扰项的来源。就像托尔斯泰说那样:“幸福的家庭都是相似的,不幸的家庭各有各的不幸”,系列课件没有办法列出全部错误类型,因为不同水平的学生,不同的题型,都会出现千差万别的错误。希望同学们能少走弯路、举一反三,提高定语从句的解题能力。
误区一、把普通代词当作关系代词用
关系代词首先是连词,可以连接句子。在定语从句中代指作为先行词的名词、代词或句子,并在从句中作主语、宾语、表语或定语。it, they, them, they, he, she, their, its等只是普通代词,因此不能连接句子。
【考例1】 The children, ______ had played the whole
day long, were worn out.
A. all of what B. all of which
C. all of them D. all of whom
【解析】D。根据句子的谓语动词had played和were worn out看出需要连词连接句子,C项的them只是人称代词,不是连词,所以先排除C项。句子是非限制性定语从句,且先行词指人。故选D。
【考例2】 is often the case with children, Amy was
better by the time the doctor arrived.
A. It B. That C. What D. As
【解析】D。it是普通代词,不可以连接句子,首先排除。as引导非限制性定语从句可以放在句首,what不引导定语从句。故选D。就像其他小孩子的情况一样,医生到达时Amy 好多了.本句可以转换为:It is often the case with children that Amy was better by the time the doctor arrived.
【考例3】Have you sent thank-you notes to the relatives
from______ you received gifts
A. which B. them C. that D. whom
【点拨】D。虽然them意思符合,但是不能连接句子。
介词后不用关系代词that,先行词relatives指人。故选C。
误区二、被代替成分仍然出现在定语从句中
定语从句的关系代词或关系副词在定语从句中代替前面的先行词,既然被代替了,原来被代替的成分就不应该再出现在从句里,否则就会成分重复。
【误句】On Aug. 17, 2012, Twenty-eight Chinese athletes who they won gold medals at the London 2012 Olympics were honored by the Communist Youth League of China (CYLC) and the All-China Women's Federation (ACWF) for their performances at the Games.
【点拨】删掉who后面的they,因为关系代词who已经代替先行词athletes。注意不能去掉 who,即使they去掉后也不可以,因为作主语的关系代词是不可以省掉的。
【考例】 The house I grew up ________ has been
taken down and replaced by an office building.
A. in it B. in C. in that D. in which
【点拨】B。仅根据句意看in it应该没有问题,但从语法上看,先行词house后省掉了在定语从句中作介词in的宾语的关系代词that/which,补全就是:The house that/which I grew up in has been taken down and replaced by an office building.。故选B。
误区三、认为先行词指时间、地点和原因就用关系副词when,where和why
定语从句的先行词并不是决定关系代词或关系副词的唯一条件,真正决定关系词的是所用关系词在定语从句中所作的成分,只有关系词在从句中作状语时才用关系副词,否则要用关系代词。reason后的内容如果是同位语则用that引导同位语从句,不用which。
【考例1】 Finally he reached a lonely island _______
was completely cut off from the outside world.
A. when B. where
C. which D. whom
【点拨】C。虽然先行词island是指地点的名词,但是从句没有主语,即要用关系代词作主语,先行词指物。故选C。
【考例2】 An ecosystem consists of the living and nonliving things in an area _____ interact with one another.
A. that B. where C. who D. what
【点拨】A。withdrawn的意思是退出,题中定语从句的先行词是the living and nonliving things,area不是先行词,不能想当然认为area是指地点的名词就选where。从句缺少主语,用关系代词。故选A。句意是:生态系统包括某个地区内相互作用的生物和非生物。
【考例3】By 16:30, __ was almost closing time, nearly all the paintings had been sold.
A. which B. when C. what D. that
【点拨】A。先行词16:30虽然指时间,但是从句中需要的是主语,用关系代词which引导非限制性定语从句,不用关系副词when。故选A。
误区四、认为定语从句前面的词就是先行词
定语从句一般紧跟在先行词的后面, 但有时为了行文的需要, 先行词和定语从句也会被同位语、状语、谓语、定语等成分隔开,即我们平时所说的分隔式定语从句。解题时通过去掉句子枝干部分,使得句子的结构更加明晰,从而找出先行词。
【考例1】Ellen was a painter of birds and of nature, _____,
for some reason, had withdrawn from all human society.
A. which B. who C. where D. whom
【点拨】B。题干中的nature虽然在要填的关系代词前,但从后面的谓语部分“避开所有人类社会”看出先行词是指人的名词Ellen。故选B。句意是: 艾伦是一位鸟类和自然画家,出于某些原因,他已经远离世俗的烦扰。(脱离尘世的喧嚣)
【考例2】 She has a gift for creating an atmosphere
for her students ____ allows them to communicate
freely with each other.
A. which B. where C. what D. who
【点拨】A。“让他们可以相互自由的交流”的动作是atmosphere发出,并非students,所以先行词是atmosphere,用which, 不能用who。故选A。
句意:她具有给学生营造一种让他们自由交流的氛围的天赋。
误区五、of whom和of which就可以换成whose
whose=of whom(which)的前提条件是of whom(which)
表示所属关系,如果不是所属关系,二者不可互换。
【误句】Now, there were two possessions of the James
Dillingham Youngs whose they both were proud.
【点拨】whose改为 of which。根据句意和从句的were proud看出是短语be proud of,不存在所属关系。句意:现在,詹姆斯·迪林汉姆·杨夫妇俩各有一件引以为豪的东西 (Jim
附:本句背景--- 圣诞节是西方国家最重要的节日之一。每年的12月25日,人们都会在欢乐的气氛中互赠礼物以表祝福。那些各种各样的礼物把寒冷的平安夜变成温暖的天堂。但是,怎样的礼物才是最珍贵的呢?美国短篇小说家欧·亨利为我们描述了一个普通却内意深刻的故事——《麦琪的礼物》。
《麦琪的礼物》中所讲述的故事,是一个圣诞节里
发生在社会下层的小家庭中荒唐却感人的故事。男主
人公吉姆是一位薪金仅够维持生活的小职员,女主人
公德拉是一位贤惠善良的主妇。他们的生活贫穷,但
吉姆和德拉各自拥有一样极珍贵的宝物——吉姆祖传
的一块金表,德拉一头美丽的瀑布般的秀发。为了能在圣诞节送给对方一件礼物,吉姆卖掉了他的金表为德拉买了一套“纯玳瑁做的,边上镶着珠宝”的梳子;德拉卖掉了自己的长发为吉姆买了一条白金表链。他们都为对方舍弃了自己最宝贵的东西,而换来的礼物却因此变得毫无作用了。
吉姆和德拉,即使只是生活在社会底层的小人物,却拥有着对生活的热情和对对方的深爱,在这些温暖的感情面前,贫困可以变得微不足道。在圣诞节前夕,两个人还想着要为对方买一件礼物互赠,多么浪漫多么温馨。即使这一份礼物似乎失去了使用的价值,它们却成了世间最珍贵的礼物,变成一份真挚的爱赠给了对方。
误区六、as和which引导的非限制性定语从句都可以换用
虽然as和which都可以引导非限制性定语从句,但是在句首、表示“正如或就像”要用as,如as is often the case,as was expected,as often happens,as is known to all,as has been said before,as is mentioned above等。表示意料之外或者表示结果用which。
【误句】Bamboo is hollow inside, as makes it very light.
【点拨】as改为which。“竹子轻”是“中间空”的结果。
【考例】A lot of language learning, has been discovered,
is happening in the first year of life, so parents should talk
much to their children during that period.
A. as B. it C. which D. this
【点拨】A。根据so后内容和从句的现在完成时看出“孩子在出生的第一年就已经有许多语言学习活动”,这一点是大家已经发现的,用as引导。故选A。
误区七、定语从句有 the same, such, so就一定用as
as作为关系代词引导限制性定语从句时常与the same, such, so连用,表示“类似的,如此的,同类的”,但是当表示就是那个(些)是用that。同时要注意区分定语从句与结果状语从句, such(so)…that中的that引导结果状语从句时,去其中的that不作任何成分,如果是定语从句,则作主语、宾语等成分。
【误句1】There was only one house left, so I had to
buy such an unsatisfying house as he offered me.
【误句2】These houses are sold at such a low price
as some people expect to buy one more.
【点拨】句1前面only one表明只有一栋房子,由其唯一性知道并不表示“类似的房屋”,而表示“就是这栋房子”,所以as改为that。句2从句不缺少成分,不可能是关系代词引导的定语从句,根据句意看出是so… that …引导的结果状语,所以as改为that。
关系代词whose在所引导的定语从句中表示“……的”,可以指人也可以指物。但是在解题时,由于受who和whom指人的思维定势的影响,从而忽视指物的作用。
误区八、关系代词whose的先行词只能指人,只有whose才可以作定语
【考例1】The school shop, customers are mainly
students, is closed few the holidays.
A. which B. whose C. when D. where
【点拨】B。先行词shop指物,容易误选 which。此处的关系词作定语,whose可以表示物,whose=of which, 即:whose customers=the customers of which,表示所属关系。故选B。
【考例2】He may win the competition, _________
he is likely to get into the national team.
A. in which case B. in that case
C. in what case D. in whose case
【解析】A。本句是非限制性定语从句,排除C, that作为关系代词不能引导非限制性定语从句,作为指示代词不可以连接句子,排除B项。关系代词which代替短语in that(this) case 中的指示代词that(this),先行词是前面整个句子。故选A。
误区九、one of n(pl) who… 结构中的定语从句的谓语动词一定用复数
在主谓一致关系中,one of n(pl)作主语时,谓语动词用单数。在定语从句中,one of n(pl) who…结构的谓语动词通常用复数,但是如果one前面有限定词,则定语从句的谓语动词用单数。
【典例】He is the only one of the students in our class who _____ a winner of scholarship in three years.
A. is B. are C. have been D. has been
【点拨】D。one前面被the only修饰,关系代词who应代指one,因此谓语动词用单数,再根据in three years“三年以来”看出用现在完成时。故选D。
误区十、that和which指物时都可以换用
只用that:①先行词被形容词最高级或the first, the last等序数词修饰时;②主句是以who或which开头的特殊疑问句时;③当先行词是不定代词all, little, much, any, the one, something, anything, everything , nothing或者被all, little, much, no, any所修饰时;④先行词被the only(唯一的),the very修饰时;⑤当在从句中作表语时;⑥先行词既有人又有物时。
只用which:①引导非限制性定语从句时;②在“介词+关系代词”结构中。
【考例1】We have launched another man-made satellite,
is announced in today’s newspaper.
A. that B. which C. who D. what
【点拨】B。先行词是前面的整个句子,that不引导非限制性定语从句,who的先行词应该是指人的名词或代词, what引导名词性从句。选B。
【考例2】Maria has written two novels,
both of ___ have been made into television series.
A. them B. that C. which D. what
【点拨】C。“介词+关系代词”结构中不用关系代
词that,而且that一般也不引导非限制性定语从句
。故选C。
