Grammar——定语从句(3)
一、语法图解
二、语法突破
当关系代词在定语从句中作介词的宾语时，我们通常用“介词＋关系代词”引导定语从句。如果指人，用“介词＋whm”；如果指物，用“介词＋which”。
1．关系代词前介词选择的原则
(1)根据定语从句中的谓语动词或形容词和介词的搭配关系选择。
There cmes Tm, fr whm I have been waiting an hur r s.
汤姆来了，我等了他大约一个小时了。
(2)根据定语从句中介词与先行词的搭配关系选择。
The ld wman with whm yu talked just nw is a famus artist.
刚才和你们说话的老太太是一个著名的艺术家。
(3)根据句子的意思选择。
Thank yu fr yur help, withut which we culdn't have finished the task n time.
谢谢你的帮助，没有你的帮助，我们就不能按时完成任务。

2．“介词＋关系代词”的几种常见结构
(1)“介词＋which”在定语从句中分别可作时间、地点和原因状语，代替相应的关系副词when, where和why。
I ften think f the mment at which (＝when) I saw the UFO.
我常常想起我看见不明飞行物的那一刻。
The plice searched the huse in which (＝where) the thief had stayed.
警察搜查了那个小偷待过的房子。
I dn't knw the reasn fr which (＝why) he perfrmed badly.
我不知道他为什么表现差。
(2)“代词/数词＋f＋which/whm”引导定语从句。
这个结构中，代词常常为all, each, ne, many, much, mst, sme, nne, bth等，“代词＋f＋which/whm”通常在定语从句中作主语，说明整体中的一部分。有时候也可把“f＋which/whm”置于代词或数词前。
He has lts f hbbies, ne f which is swimming.
他有很多爱好，其中之一是游泳。
The ld man has three sns, all f whm care abut him.
那位老人有三个儿子，他们都很关心他。
(3)“the＋名词＋f which/whm”引导定语从句。
这个结构中，f which/whm充当定语，修饰前面的名词，整个结构相当于“whse＋名词”引导的定语从句。
I saw sme trees, the leaves f which(＝whse leaves) were yellw with disease.
我看见一些树，它们的叶子因害病而发黄。
On the blackbard the teacher wrte a sentence, the meaning f which(＝whse meaning) I dn't understand.
老师在黑板上写了一个句子，句子的意思我不明白。
(4)“the＋形容词比较级(最高级)＋f＋which/whm”引导定语从句。
There are tw buildings, the larger f which stands nearly a hundred feet in height.
这儿有两座建筑物，较大的那座几乎有100英尺高。

(教材P65) In sentence (a), can we replace “in which” with “where” withut changing the meaning?
在句(a)中，在不改变句意的情况下，我们能用“where”代替“in which”吗？
(1)replace sth.with/by sth. 用……代替/替换……
replace 代替……成为
(2)take the place f sb.＝take ne's place代替某人
in place f 代替
