★ 有时置于关系代词之前的介词能被移到定语从句的句中(或句尾)。当介词被移后时,关系代词 whom 可以换成 who 或 that ;which 可以换成 that (特殊情况除外),而且 whom 、who、that 、 which 皆可省去。如:

Do you know the boy to whom I spoke just now ? = Do you know the boy (whom / who / that ) I spoke to just now ?
The pen with which I\'m writing is not mine . = The pen (which / that) I\'m writing with is not mine .
This is the house in which I once lived . = This is the house (which / that) I once lived in .
★ 当先行词是表示时间、地点、原因的名词,而且“介词 + which ”在定语从句中分别是作时间状语、地点状语、原因状语,“介词 + which ”可分别被关系副词 when 、 where 、why 替代。如:
I still remember the day on which ( = when ) I met Professor Smith .
This is the house in which ( = where ) I once lived .
I don\'t know the reason for which ( = why ) he went abroad .
但下面一句中的“ to which ”不能换成“ where ”,因为,它不是作地点状语的。
This is the house to which we paid a visit last month .
2. 介词的选择。
定语从句由“介词 + 关系代词”引导时,介词的选择受上下文的制约。在结合语意的基础上,可以从下面几个角度判断该用什么介词。
★ 看先行词与哪一个介词是习惯“介 + 名 ” 搭配的。如:
This is the factory in which he works . ( in the factory 在工厂)
This is the farm on which he works .( on the farm 在农场)
★ 看定语从句中的动词是与哪一个介词形成习惯“动 + 介 ”搭配。如:
The car on which he spent 40,000 yuan is made in N anjing . (spend money on sth .)
The car for which he paid 40,000 yuan is made in Nanjing . (pay money for sth .)
★ 既要看定语从句中的动词,又要看先行词有何习惯“动 + 介 + 名”搭配。如:
I don\'t know the student with whom Mary quarreled yesterday . (quarrel with sb .)
I don\'t know the thing about which they quarreled yesterday . (quarrel about sth . )
3. “介词 + 关系代词”的复杂化
★ 复合介词 + 关系代词
关系代词之前除了能用简单介词外,也能用复合介词。如:
Tom studies in a new school , at the back of which there is a big river .
She gave a friendly smile to the worker , in front of whom sat a little cat .
★ 名词(〈不定〉代词、数词、形容词最高级)+ of + 关系代词
例如: I live in an old house , whose door is made of bamboo .
注意:“ whose +名词”常可换成“名词 + of + 关系代词( whom / which )”上句可改成:
I live in an old house , whose door is made of bamboo .
She has two sons , neither of whom is tall .
In our class there are fifty students , most of whom are good at English .
I talked with an old worker , one of whose daughters is a scientist .
China has thousands of rivers , the longest of which is the Changjiang River .
二、whose 引导的定语从句
whose 是英语中唯一能够在定语从句中充当定语的一个关系代词,意为“……的”。它既可引导限制性定语从句,也可引导非限制性定语从句。与that , whom , which 又有着截然不同的用法。同学们须认真掌握,其主要用法如下:
1. 指人。
Do you know the boy whose brother is a postman ?
This is the student whose handwriting is the best in our school .
2. 指物。
The lives in a small room , whose windows face the north .
I want to buy the coat whose colour is the lightest .
注意:(1) whose 指人时,一般可以和 of whom 互换。
Do you know the boy , the brother of whom is a postman ?
This is the student , the handwriting of whom is the best in our school .
(2) whose 指物时,一般可以和 of which 互换。
He lives in a room , the windows of which face the north .
I want to buy the coat , the colour of which is the lightest .
3. whose 引导的定语从句作主语的定语时,一般不用 of which / whom来替换。
Mr Li , whose car was stolen last week , got very angry .
The factory , whose boss hurt in the accident , produces a lot of useful things every year .
4. 如果主句是由who , which等引导的疑问句,从句中最好不用 whose , 以免意义混乱。
Who is that girl , the mother of whom died last month ?
Whose is the house , the windows of which are all broken ?
