whenthat/which定语从句 在主从复合句中,修饰某一名词或代词的从句叫定语从句。定语从句在句中相当于一个形容词,起“定语”的作用,修饰说明名词、代词或主句全部内容;被修饰的名词或代词叫先行词,引导定语从句的词叫引导词,定语从句通常放在先行词的后面。The man who lives next to us sells vegetables.先行词放置于名词之_____,修饰
名词的从句关系词连接作用1.2. 在从句中充当成分后 引导词:
关系代词: who, whom, whose, that,
which
关系副词: when, where, why 要做好定语从句有关试题,就得必须理解透 “关系词”具有的三种功能:
(1) 引导一个定语从句。(在定语从句开头)
(2) 替代“先行词”。(省去从句中对应的he/ she/ it/ they/ him/ her/ them/…)
(3) 在定语从句中充当成分。(作主语/宾语/定语 /表语/状语)1. 由 who,whom,whose 引导的定语
从句。
这类定语从句中 who 用作主语,whom 作宾语,whose 作定语。
This is the man who helped me.
这位是帮过我的那个人。用法:The Doctor whom you are looking for is in the room.
你找的那位大夫在屋里。
Do you know the man whose name is Liu Ming?
你认识那个叫刘明的人吗? 2. which 引导的定语从句
这类从句只能指物,which 在从句中 作主语或谓语动词或介词的宾语。
This is the book which you want.
这就是你要的那本书。
The building which stands near
the river is our school.
河边的那栋楼是我们学校。 The room in which there is a machine is a workshop.
有机器的房间是车间。
1) whom,whose,which 作介词宾语时,介词一般可放在它们之前, 也可放在从句原来的位置上, 在含有介词的动词固定词组中, 介词只能放在原来的位置上。 This is the person whom you are looking for.
这位就是你在找的那个人。
2) 引导非限定性定语从句时,关系代 词往往用 which, 不用 that。
I have lost my book, which I like very much. 注意!3. 由 that 引导的定语从句
that 在定语从句中可以指人或物,在从句中作主语或谓语动词的宾语。但不能放在介词后面作介词宾语。
The letter that I received was from my father.
我收到的那封信是我父亲写给我的。【真题回顾】

That dog I found in the street belongs to Mary.
He is the only person I want to talk to.

thatwhichthat
that
难点1. 在下面几种情况下必须用“that”引导定语从句:
先行词是不定代词: all, few, little, much, something, nothing, anything 等。
2) 先行词被序数词或形容词最高级所修饰。
3) 先行词被 all, any, every, each, few, little, no, some 等修饰。
4) 先行词被 the only, the very, the last 修饰时。
5) 先行词既有人又有物时。
注意!只能使用which的情况:
1、非限制性定语从句中。
2、在介词之后。
3、当主句中的主语被that修饰时。
Who is the girl is standing over there?
I have a son, is really lovely and interesting.
There are 40 students in the class, most of are boys.
Practice 2thatwhowhom选填that 和who, whom难点2. 修饰人时关系代词that 和who, whom的区分。
当主句中的主语是who时,只能用that。
在非限制性定语从句中以及介词后面时只能用who 或者whom。
He failed in the exam, made his parents angry.
we had expected, he failed in the exam.
Practice 3选填as和whichwhichAs难点3. 关系代词as与which引导非限制性定语从句的区别.
1.位置:as从句可在主句前或主句后,而which从句只可在主句后.
2.意义:as从句常是一些固定结构,(如as is known to all, as we expected, as everybody knows等,而且译为”正如….,恰如…”.) the same…as, such… as,和……一样. which从句多为对主句的一种评价看法,或者主从句之间形成一种因果关系.关系副词when, where, why引导的定语从句,它们可代替的先行词是时间、地点或理由的名词,在从句中作状语。 People could live in the place where they landed.4. 由 when,where,why 引导的定语从句。关系副词when, where, why的用法
关系副词在定语从句当中只能充当状语,当一个句子能够完整地表达一个意思时,我们就可以给这个句子加上特定的关系副词。
I won’t forget the time I got married.
Is this the house Mr. Smith lives?
I don’t know the reason he won’t join us.
whenwherewhy关系副词when, where, why和关系代词that, which的区分。
请比较以下句子:
She won’t forget the days she spent on the island.
从句可还原为:She spent the days on the island.
That’s the date we went to the college.
还原为:We went to the college on the date. (on which=when)
that/whichwhenPractice 4This is the park we visited last year.
还原为:We visited the park last year.
This is the park we held a birthday party.
还原为:We held a birthday party in the park. (in which=where)
that/whichwhereThis is the reason he gave to me.
还原为:He gave the reason to me.
Do you know the reason he didn’t come to sweep the classroom?
还原为:He didn’t come to sweep the classroom for the reason. (for which=why)
that/whichwhy注意:用关系代词还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。准确判断先行词在定语从句中的成分也能正确选择出关系代词/关系副词。由于学生分不清句中的成分,强烈推荐学生用本人自创的从句还原法来判断。 关系副词when, where, why 和介词+which之间的关系
关系副词when, where, why可以用适当的介词+which来替代。如:when=in/on/at…+which, where=in/on/at…+which,
why=for +which
介词的位置非常灵活,有时放在关系
代词之前,有时放在动词之后。1. I won’t forget the date _______________ I was born.
2. This is the room ______________ I lived. = This is the room which I lived in.
3. I don’t know the reason _____________ he hasn’t come yet.
