“介词+which"引导的 定语从句 陈静学 (两北大学,陕西两安定语从句是英语语法中非常重要的内容.在阅读和理 710063) 解过程巾起着极其重要的作用。在多年的教学中,发现学生 们经常提的问题就是长句子的理解与翻译,而这恰恰是考 试中的侧重点.也就是出考题的密集点。同时也是学生们在 考试中丢失分数的密集点。考试阅读题经常是四、五篇文 章,其长句的理解决定着这部分的得分高低。有许多学生阅 读能力薄弱,不能透彻地理解英语句子,失分很多。有时,在 考试的 读题里,在长句子下面画线要求对此进行翻译,不 仅考理解力,而且考表达能力,在短时间内理解准确,表达 流利无误,需要下功夫学习与训练,不是一蹴而就的事情。 这部分花时间来钻研.不仅利于考试,而且有利于提高英语 运用能力.能极好地促进英语写作.为考试取得好成绩打下 坚实的基础。 其中“介词+which”的情况实际上就是which在从句中作介 词宾语的情况.更是学生难点中的难点,所以,本文就这一个 问题进行系统的讲解。 这种定语从句仍然一定遵循“关系代词指代哪个词,定语 从句就修饰那个词”这一原则。对于这类定语从句,我们从以 下三个方面来论述。 1.“介词+which”在从句中作状语 这种情况是最常见的。即of是从句中的动词或形容词所 要求搭配的,所以ofwhich在从句巾作状语。这是,在少数情况 下也可以是“短语介词+which”的形式。当“介 ̄+which”在从 句中作状语时.“介词+which”必定位于从句的句首,定语从句 就从该介词开始。如: (1)“单个介词+which”的情况,例如: (1) rI1e two elements of which water is nlade are oxygen alld hydrogen. 构成水的两个元素是氧和氢。 (2)Speciifc diseases of which these abnormal muscle contrac— tions are symptomatic will be discussed later. 这些肌肉的异常收缩所表征的具体的疾病将在以后加以 讨论。 ③Chemistry deals with changes墅 堡 坚! it is pos— sible to fornl a new substance. 化学是论述能形成新物质的那种物质变化的。 of与从句中的少数动词或形容同构成同定搭配。常见的 这类动词词组或形容词词组如下: consist of be buiIt of descriptivc of be composed of capable of representative of be made of aware of characteristic of sure of be made up of symptomatic of be constructed of 提示: 该结构中“介词”的正确选择方法: 1)由从句中的动词、形容词或名词所确定,如: Copper is one of the metals with which we are most famil一 铜是我们最熟悉的金属之一。(形容词familiar与with连用) How to live longer is a question to which man has tried to ifnd a good answer for thousands of years. 如何才能长寿,是人类数千年来力图寻求良好答案的问 题。(名词answer卜jto连用) 下面列tt卜一些常见词汇与介词的搭配情况: 1O6 :es:ak Isne  I『1  memo.hodo]l difficuIt ith which pp roce rdu Ie}f  ep雎c “l I techniquejI  aceuracy J +by which req pr essure]Y  t which temperature f rate J 2)由被修饰的词所确定,如: ①He signed an agreement under which he would be entitled to a commission on sales. 他签订了一项协议,这可使他获得销售佣金。 ②The language teachers association provides a medium through which ideas can be shared and discussed. 语言教师协会提供了一种交流和讨论意见的媒介。 3)根据整个句子所要表达的含义来确定,如: The substance in which there are many electrons is a good c0ndIjctor. 含有大量自由电子的物质,是良导体。(这个in并不是那 个词所特需的) Inasmuch as this book has been written primarily for people to whom the material is new.1 feel such an approach is pedagogi- cally superior. 由于本书主要是为没有学过这个内容的人编写的,所以 我感到这样的方法从教学法角度讲是很优越的。 (2)“短语动词+which”的情况,常见的形式如下: in terms of which bv means of which as a result of which according to which in accor(1ance With which on the basis of which because of which relative to which with respect to which by the help of which by virtue of which 2.“介词+which”在从句中作定语 ・ 这种情况并不常见。在从句中作定语时“介词+which”一 般并不出现在从旬的句首,而是在从句中。如: (1)No part of this publication may be reproduced or transmit— ted in any form or by any means without the written permission of the copyright holder,application for which should be addressed to the Publishers. 未经版权所有者的书面许可.本书的任何内容均不得以 任何形式或用任何手段进行翻印或传播:若要提出申请,应提 交给出版社。(这里which代替了thewrittenpermission) (2)More than one hundred elements two thirds of which are metals have been found SO far. 到目前为止.人们已发现了一百多种化学元素。其中三分 之二是金属。(ofwhich在此修饰从句的主语two thirds;但which 代替了more than one hundred elements,所以定语从句是从ele. ments后面开始。) 3.ofwhich在定语从句中的情况 ofwhich与上述一般的“介词+which”的情况是一样的,它 在从旬中有以下两种功能: (1)ofwhich在从句中作状语。 (2)这时,ofwhich只能位于从句的句首。0f与从句中的少 数动词或形容词构成固定搭配。(详见以上ofwhich在从句中 作状语)又如: Since the eye cannot focus on objects closer than the near point,this sets a limit to the magnification of which the eye is ca— pable. b.ofwhich表示“其中”(即部分与整体的关系)之意时,绝 不能用whose来替代。常见的形式是“不定代词、数词等+ of which”,关系代词除which外,还可以是whom,whose,主要 如下: one of which... either of which... each of which... some ofwhich... a few of which... both of which... neither of which... many ofwhich... nluch of which... most of which... 由于眼睛不能聚焦于比近点还近的物体.这就了眼 睛所能实现的放大量。 (3)ofwhich在从句中作定语,这中情况比较常见。 1)ofwhich在从句中修饰主语。 a.表示“所属”:这种情况最常见,这时,ofwhich一般位于 从句的主语后面。在这里,有必要把whose和ofwhich结合起来 aJl of which… any of which...none of which… the first of which... a part of which...the most important of which... rhe body is composed of specialized groups of cells,the ifrst of which are called tissues. 讲解,这样有利于理解ofwhich。作为关系限定词.whose既可指 人,也可指物,既可用于性定语从句,也可用于非性 定语从句。 whose指人。如: 人体是由各种特殊的细胞群构成的,其中第一种被称为 组织。 ②T s idea can be readily applied to members of the animal kingdom,all of whonl maintain about the same temperature and have about the same density. ①That’s the man whose house was burned down. 那就是住房被烧的人。 @This is George,whose class you will be taking next week. 这就是乔治,你下周将听他的课。 whose指物。如: (1)That’s the new machine whose parts are too small to be seen. 这一概念可容易地应用于动物王国的成员中,所以这些 成员保持着大约相同的体温,同时具有大致相同的密度。(注 意:由于定语从句修饰的是动物,所以使用了whom而不是 which。) . ⑧The storekeeper in the neighborhood,some of whom had already been robbed,asked for more police protection. 是肉眼看不见其微小部件的新机器。 ( This factory,whose workers are all women,is closed fo part of the school holidays. 附近商店的店员们请求警方给予更多的保护,因为他们 当中的有些人曾被抢过。 ( The residents,all of whose homes had been damaged by the lood,were given fhelp by the Red Cross. 这个工厂,由于工厂工人都是妇女,常在学校假期关闭一 段时间 关系限定词whose在正式语体中常为ofwhich所代替,用于 指物。如: That’s the new machine the parts of which are too small to be 这些居民们的家全被洪水冲毁了.他们得到了红十字会 的帮助 ⑤The eighty—nine passengers all escaped without serious in— seen.(译文同上) 也可以把ofwhich直接置于先行项之后: That’s the new machine of which the parts are too small to be jury,four of whom were Americans. 89名乘客全部脱险而没受重伤.其中有4个是美国人。 提示: seen.(译文同上) 又例如: I saw some old buildings whose windows were all broken. 若为了加强“其中”的含义,并且从句主语不是某些不定 代词或被no,any,各种代词修饰时,可以把ofwhich放在从句主 语前。如: The first stage ofthe rocket has a total mass of 12,000 kg, 我看见一些老房子,门窗都破损了。 (2)I saw some old buildings the windows of which were all ofwhich 9000kg(=9,000kg ofwhich)is fue1. 该火箭第一级的总质量为12000 ̄克,其中900O千克是燃料。 ( When testing ended on 25 November 1973,the total oper— ating time was 374,580 hours,ofwhich the last 104,580 hours(= broken.(译文同上) (13)I saw some old buildings of which the windows were all broken.(译文同上) 提示: 如果ofwhich所修饰的词前没有no,any,各种代词等时,它 般就可用whose来替代,但whose只能放在被修饰的词前面, 且被修饰词前面的冠词要去掉,如: 一the last 104,580 hours of which)were failure-flee. 当1973年l1月25日试验结束时,总的工作时间为375580 小时。其中最后的】04580d ̄时是无故障时间。 如果ofwhich在从句中修饰there be句型的主语的话.它只 能放在从句的句首。如: There are different substances,of which there is indeed an enormous number. Mechanics is the physical theor ̄the task of which(=whose task)is to describe motion. 力学,是一种旨在描述运动的物理理论。 为了加强语气.也可SEofwhich放在从句主语的前面(这 并不多见)即. Meehanics is the physical theory of which the task(= whose task)is to describe motion. (世界上)有着许多不同的物质,事实上其种类甚多。(of which在从句中是修饰an enormous number的。) 2)ofwhich在从句巾修饰表语时,一定要放在从句的句 首。如: Faraday joined the City Philosophical Society,of which he became a very keen member. ( The earth is a planet ofwhich the surface(=the surface of which=whose surface)is surrounded by a layer of atmosphere. 地球是一颗其表面被一层大气包围着的行星。 法拉第加入了伦敦自然科学研究会,他成为该会一位很 热心的会员。 107
