定语从句介词为何前置定语从句介词何时应该前置

what = the thing/things that,因此what可以用于定语从句,但不需要先行词,换句话说,what其实引导的是名词从句.比如：
This is what I want.= This is the thing that I want.
这就是我想要的.
Do you know what they're doing?= Do you know the thing they're doing?
你知道他们在做什么吗?
What caused the accident were stones.= The things that caused the accident were stones.
一些石头导致了这起事故.

it不是关系代词,这个地方应该用关系代词which,因为前面有介词without

这位同学,你好,你的问题分析如下：
（1）应该合并为：We like the places where it is warm and relaxing.
（2）（3）在时间名词和地点名词后是否用关系副词要看它在定语从句中充当什么句子成分.一般说来,若用作主语或宾语,用关系代词；若用作状语,则用关系副词.此题中缺少状语.因此用where.
谢谢

The reason was known to all that she leads a happy family.
众所周知,她有个幸福的家庭.
Owing to the reason known to all the relations between the two peoples were suspended for over twenty years.
由于众所周知的原因,两国人民间的关系中断了20多年.

非限制性定语从句,用which指代前一整句话
还原句子：she went on to have her advanced study abroad after she was educated at PEKING university
用的是after
选D

先行词前有such修饰,关系代词只能用as,不能用that或者which.

有with了,后面用宾格

B from there中的from是borrow from的搭配,指从哪里借
A most of which中的which指代前面说的a large number of pots,coins,belts and so on.此处还要注意绝对不能用that

定语从句就是作定语用的从句，定语是修饰主语或宾语的：
例一：修饰主语——
La chica que se pone a la izquierda se llama Luna.
左边那个女孩叫Luna。
例二：修饰宾语——
No repite lo que te digo.
别重复我说的话。

典型的宾语从句,that去掉后整句仍成立,而其他两个词则不可以.

1,选when,when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导.
2,选where ,where指地点
在定语从句中做地点状语 例 (1) Shanghai is the city where I was born. (2) The house where I lived t...

从句make的宾语是前面的promise.
这是定语从名的规则,从句中的谓语如果是不及物动词,介词和宾语都要放到前面,如果是及物,宾语放前面.

定语从句就是说一句有附加解释的话
he is a boy who lost 200 dollars this morning.
他就是那个人,哪个人呢?早上丢了200美金的那个人.
一般从句是限定规定前面提到的人或者物,以免混淆.
再来个例子,she has a book whose cover is red.
她有一本书,而且书的封面是红色的.

一、定语从句（一）：
1.定语从句的概念：
在复合句中,修饰某一名词或代词的从句叫定语从句.
2.先行词：
被定语从句修饰的名词或代词叫先行词.
3.关系词：
引导定语从句的连词叫关系词.如that、which、who、whom、whose、where、when等.
4.由that、which、who、whom、whose引导的定语从句.
关系词
指代
在定语从句中的作用
that
既指人也指物
作主语、宾语
which
指物
作主语、宾语
who
指人
作主语
whom
指人
作宾语
whose
既指人也指物
作定语
二、定语从句（二）
1.先行词是物时,一般情况既可用that也可用which.但下列情况下,只能用that不用which.
1).当先行词为指物的不定代词,如all、everything、something、anything、nothing、none、the one等时,只能用that.
There is nothing ______ I can do for you .
2).当先行词被the only、the very 、the last、all、no、little等词修饰时,只能用that.
This is the very book ______ I’m looking for .
3).先行词被序数词修饰时,只能用that .
This is the first nextbook ______ I studied in the middle school .
4).先行词为最高级或被最高级修饰时,只能用that.
This is the most beautiful mountain ______ I have ever seen .=
I have _____ seen _____ a beautiful mountian .
5).先行词既有人也有物时,只能that .
He told us many interesting things and persons _______ we had .
2.先行词是物时,一般情况既可用that也可用which.但下列情况下,只能用which不用that.
1).关系代词前有介词时,关系词只能用which .
This is the building in ______ he lives .
2).先行词本身是that时,关系词只能用which .
The clock is that _____ tells the time .
3).引导非限定性的定语从句（先行词是物且先行词与关系词用逗号隔开）,关系词用which.
His book ,______ was lost last week ,has been found now.
3.先行词是人时,一般情况下既可用who 也可用that .但以下情况下,只能用who.
1).当先行词为those、one、ones、anyone且作主语时,一般用who .
Those ______ are singing are all my classmates .
2).在there be 句型中,先行词指人时,只能用who.指物时用that.
There is a girl ______ expects to see you .
3).当先行词是I、you、he、they等时,只能用who .
He ______ plays with fire gets burned .
三、定语从句（三）.
由关系副词when、where、why引导的定语从句.
where = in / at +which when = in / on / at +which why = for + which
1.由where引导的定语从句.
1).先行词是表示地点的名词 2).在定语从句中作地点状语
Is this the house ______ you lived = Is this the house _____ _____ you lived
= Is this the house _____ you lived in
2.由when引导的定语从句.
1).先行词是表示时间的名词 2).在定语从句中作时间状语
I will never forget the days ______ I met him .= I will never forget the days ____ ____ I met him.
注：先行词是the last time 时,when 可省略.
When was the last time you saw the parrot
3.由why引导的定语从句.
先行词为reason 时,一般用why .why在句中作原因状语.
We don’t know the reason ______ they didn’t come .
四、注意事项：
1.关系词在定语从句中作宾语时,常可省略.
The story _____ he told was very popular .
A.who B.whom C.whose D./
2.that、who、which在定语从句中作主语时,定语从句的谓语动词应与先行词保持一致.
I loves singers who _______(write) their own songs .
She is one of the girls who ______(study) hard .
3.在定语从句中不能出现代替先行词的人称代词.
Will you please show me the book ______ yesterday?
A.which you bought B.that you bought it C.you bought D.you bought it
4.定语从句中whose 的确定：
无论先行词是人或物,在定语从句中做定语用whose.
判断：看定语从句的主语前有无限定词（my、your、Jim’s等）,若没有,则用whose .
The girl _____ parents work in Beijing is Kate .
A.who B.whose C.which D.that
I know the boy .His handwriting is very good .= I know the boy ____ handwriting is very good.

这个嘛……这样来说吧：宾语从句在动词后边充当成分 标志：动词之后；例如：I like what my boyfriend gave me. like 之后就是整个宾语从句定语从句为修饰名词的 可以理解为“打扮” 主要做修饰、解释说明 被修饰...

The poor boy whose parents are both dead is callde Tom.

定语从句即用句子来做定语,被修饰或被限制的词称作先行词,例如
1.I don't know the girl who is talking there.
2.I don't know the girl who you met just now.
3.Give me the book that you read just now.
4.Give me the book ,which you read just now.
5.Give me the pen that you write with.
6.Give me the pen with which you write .
仔细看句子中的book 和pen就是先行词,他们后面的who that which 就是引导定语从句的关系代词,当先行词是人用who,先行词是物用that,先行词后出现介词或逗号用which.
这是一种捷径,细节问题找本语法书慢慢学.

定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种.状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句.名词从句包括主语从句,宾语从句,表语从句和同位语从句及there be句型.
一、 限定性定语从句
1. that即可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略.而且,如果which在从句中作“不及物动词＋介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略
4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5. where是关系副词,用来表示地点的定语从句
6. when引导定语从句表示时间
〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
By the time you arrive in London, we will have stayed there for two weeks.
I still remember the first time I met her.
Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.
7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格
8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导
二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立
1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which
Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处.
I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反.
We arrived the day that(on which) they left. 刚好我们到的那天他们走了.
3. 有时as也可用作关系代词
4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物
三、定语从句结构错误
1. 缺关系词
2. 从句中缺成分
摘自《简明英语语法》
在英文中,有两种定语从句：限定性定语从句与非限定性定语从句.这两种定语从句在其功能和形式方面都有明显的区别：
限定性定语从句限定性定语从句与主句的关系很紧奏,对其先行词起限定、修饰的作用.如果将其去掉,会影响句子意思的完整性；有时甚至于引起费解、误解.例如：
Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located .
为了加速他们各自所在国家的经济发展,热带雨林作为有价值的原木和其他资源正为人们所砍伐.
Ocean currents affect the climates of the lands near which they flow.
洋流影响其流经的附近地区的气候.
They explained the reason to us why they had hated us before.
他们向我们解释为什么他们不喜欢我们的原因.
非限定性定语从句非限定性定语从句在形式上就与主句很松散,它与主句之间有一个逗点","隔开；它对其先行词没有限定、修饰的作用,只起补充、说明的作用.有时也用它来对全句进行补充、说明.即使将其去掉,也不会影响句子意思.由于上述原因,非限定性定语从句在表达意思方面也有别于限定性定语从句.另外,非限定性定语从句在中文译文里,我们往往将其作为一个分句处理,而不把它作定语翻译. 例如：Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy .
（此句中,非限定性定语从句是对先行词a sphere进行补充、说明.）
更早之前,巴比伦人曾试图绘制世界地图,但是他们把它绘制成平盘状而不是托勒密所采用的球体状.
The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an education and entertainment center .
（此句中,三个非限定性定语从句分别对三个先行词：satellites ,computers和television进行补充、说明.如果去掉这三个非限定性定语从句,那么句子可简化为：
The combination of satellites , computers and television will change every home into an education and entertainment center .）卫星能传输信息,计算机能储存信息,电视能显示信息,把这些手段结合起来可以使每个家庭都成为教育娱乐的中心.
The sun heats the earth , which makes it possible for plants to grow .（此句中,非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情）.太阳给予大地热,这就使植物的生长成为可能.
The old man has a son , who is in the army .（此句中,非限定性定语从句是对先行词son进行补充、说明.但本句所传达的信息是："这位老人只有一个儿子" .如果将此句改写成限定性定语从句：
The old man has a son who is in the army . 那位老人有一个在部队工作的儿子.那么,限定性定语从句就要对先行词son进行限定、修饰.这样一来,句子所传达的信息就变成了："这位老人有一个儿子在部队工作,还有其他的儿子在干别的工作".）那位老人有一个儿子,他在部队工作.

1.宾语从句
1）宾语从句可位于及物动词、介词和某些形容词后.连词that常可省略.介词后一般接疑问词引导的宾语从句.in that(因为),except that(除了),but that(只是）已构成固定搭配,其他介词后一般不接that引导的宾语从句.
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)宾语从句后如有宾补,要用形式宾语it来代替,而把宾语从句移至宾补之后.
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等动词后的宾语从句中,如果谓语是否定的,一般将否定词移至主句谓语上,宾语从句则变成肯定形式.
He didn't think that the money was well spent.
2.定语从句
定语从句所修饰的先行词可以是名词或代词,也可以是一个句子.定语从句通常位于先行词之后,由关系代词或关系副词引导.
*限制性定语从句
限制性定语从句修饰先行词,对先行词起修饰作用,紧接先行词之后,无逗号,若省去,原句意思不完整.引导定语从句的关系代词有who,whom,whose,which,that等.who,whom,whose用于指人,whose有时也可指物,相当于of which；which用于指物；that既可指人也可指物,但只用于限制性定语从句中.关系代词除了引导定语从句,替代先行词外,还在从句中担任主语、宾语、定语等.
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时,只能用关系代词that引导从句.
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)关系代词的省略
在从句中作宾语的关系代词常可省略.关系代词紧跟介词,作介词宾语时不可用that,只可用which或whom引导从句,并且不可省略,但当介词位于宾语从句句末时,作为介词宾语的关系代词仍可用that,也可省略.
This is one of those things with which we have to put up.
This is one of those things (whichthat) we have to put up with.
3)引导定语从句的关系副词有when,where,why等.关系副词在从句中作状语,意义上相当于一个“介词+which”的结构.
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
*非限制性定语从句
非限制性定语从句既可修饰先行词,也可修饰整个主句,起补充说明作用,与主句之间有逗号隔开,若省去,原句意思不受影响.不可用that引导非限制性定语从句.关系词不可省略.
Every object has a gravitational pull,which is rather like magnetism.
*“介词+whichwhomwhose”引导的定语从句
“介词+whichwhomwhose”可引导限制性定语从句,也可引导非限制性定语从句,该结构中介词的选择取决于从句谓语动词的固定搭配,或先行词的习惯搭配.
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中,代替先行词是人或物的名词.as引导非限制性定语从句时,代替整个主句,从句可位于主句之前、之后或中间.
These are not such problems as can be easily solved.(as代替先行词problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)
3.状语从句
*时间状语从句
引导时间状语从句的从属连词和词组有：
1）when,whenever,while,as,after,before,since,till,until,once等.
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等.
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.
*地点状语从句
引导地点状语从句的连词是where,wherever.
Wherever she went,she took her little daughter with her.
*原因、结果和目的状语从句
1）引导原因状语从句的从属连词有：because,as,since,now(that),seeing that,considering that,in that等.
Considering that he is a freshman,we must say he is doing well.
2)引导结果状语从句的连词有：so...that,such...that
,so that,that,so等.
Mickey Mouse is so attractive that the children are reluctant to leave.
3)引导目的状语从句的连词有：so that,in order that,for fear that,lest等,从句常使用may,might,can,could,would等情态动词.
We got up early this morning so that we could catch the first bus to the railway station.
*条件和让步状语从句
1）引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等.
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however.)等.though,even if等引导状语从句可转换成含有as的部分倒装结构,具有强调意义.其结构为“形容词（副词、动词、名词）+as+主语+谓语”.
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等.as if,as though引导的状语从句中,谓语动词常用虚拟语气,表示与事实相反.
The young man made the experiment just as the teacher had taught him.
Everything went on as usual as if nothing had happened.

定语从句的概念
　　　　在复合句中,修饰某一名词或代词的从句叫定语从句.被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面.
　　　　二、定语从句的关系词
　　　　引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that,which,who（宾格whom,所有格whose）等,关系副词包括where,when,why等.关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分.
　　　　三、定语从句的分类
　　　　根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句.限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整.
　　　　四、关系代词的用法
　　　　1.that 既可以用于指人,也可以用于指物.在从句中作主语或宾语,作主语时不可省略,作宾语可省略.例如：
　　　　Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐.（that作主语）
　　　　The coat （that） I put on the desk is blue.我放在桌子上的那件外套是蓝色的.（that作宾语）

　　　　The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人.（作主语）
　　　　Who is the teacher （whom） Li Ming is talking to?正在与李明谈话的老师是谁?（作宾语）
　　　　注意：（1）当定语从句中含有介词,介词放在句末时,who,that,which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构.例如：
　　　　This is the house in which we lived last year.这是我们去年居住的房子.
　　　　Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说.
　　　　（2）含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上.例如：
　　　　This is the person whom you are looking for.这就是你要找的那个人.
　　　　（3）that 作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面.例如：
　　　　The city that she lives in is very far away.她居住的城市非常远.
　　　　（4）关系词只能用that的情况：
　　　　a.先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如：
　　　　He was the first person that passed the exam.他是第一个通过考试的人.

　　　　I can remember well the persons and some pictures that I saw in the room.我能清楚记得我在那个房间所见到的人和一些照片.
　　　　e.以who或which引导的特殊疑问句,为避免重复,只能用that.例如：
　　　　Who is the girl that is crying?正在哭泣的那个女孩是谁?
　　　　f.主句是there be 结构,修饰主语的定语从句用that,而不用which.例如：
　　　　There is a book on the desk that belongs to Tom.桌子上那本书是汤姆的.
　　　　（5）关系词只能用which,而不用that 的情况：
　　　　a.先行词为that,those时,用which,而不用that.例如：
　　　　What’s that which is under the desk?在桌子底下的那些东西是什么?
　　　　b.关系代词前有介词时,一般用which,而不用that.例如：

　　　　c.引导非限制性定语从句,用which,而不用that.例如：
　　　　Tom came back,which made us happy.汤姆回来了,这使我们很高兴.
　　　　五、关系副词的用法
　　　　（1）when指时间,其先行词表示时间,在句中作时间状语.例如：
　　　　This was the time when he arrived.这是他到达的时间.
　　　　（2）where指地点,其先行词表示地点,在句中作地点状语.例如：

　　　　（3）why 指原因,其先行词是原因,起原因状语作用.例如：
　　　　Nobody knows the reason why he is often late for school.没人知道他为什么上学总迟到.

根据从句在句中的成分来判断.复合句是由两个或两个以上的有主谓结构的句子用从属连词连接起来的句子.其中一个句子是主体,叫做主句,而其他的句子叫做从句.从句由连接词引导,它们是:that,before,whether,if,although,because,as long as,as soon as,since,after,who,which,whom,what,whose,why,where,how,when,从句尽管有主谓结构,但不能单独成为一个句子,在句中,从句仅担任某个成分,根据担任的成分从句可分主语从句,宾语从句,表语从句,定语从句,状语从句.主语从句 在句中起主语作用的句子叫做主语从句.主语从句一般放在句首.引导主语从句的词有下列:that,who,whether,if,what,which,when,where,how,why.Who cleaned the blackboard is not known yet.谁擦的黑板还不知道.What he said is not true.他说的不是实话.That he'll come to see us is really great.他来看我们真是太好啦.It's very good that he has passed the exam.他通过了考试太好了.宾语从句 在句中起宾语作用的句子叫做宾语从句,宾语从句放在动词后面.引导宾语从句的词有下列.that,if,whether,what,which,when,where,how,why,I didn't expect that he had broken the glass.我没有想到他把玻璃打破了.Could you tell me who is your teacher?你能告诉我谁是你的教师吗?I don't know why he is absent.我不知道为什么他不在.表语从句 在句中起表语作用的句子叫做表语从句,表语从句放在系动词的后面.引导表语从句的词有下列.that,if,whether,what,which,when,where how,why等.The question is whether he will join us next time.问题是下次他是否跟我们一起干.That is why I am late.这就是我为什么迟到.定语从句 在句中起定语作用的句子叫做定语从句,定语从句放在被修饰的名词后面.引导定语从句的词有下列.who,whose,that,which,whom,when,where why.Do you know the man who is in the car.你认识坐在汽车里的人吗?This is the place where I was born.这就是我出生的地方.That is the reason why he lost his job.这就是他为什么失去工作的原因.状语从句 在句中起状语作用的句子叫做状语从句,状语从句一般放在句后,强调时放在句首.He opened the windows since it was hot.由于天气热,他打开了窗户.When he was young,he couldn't go to school.他年青的时候没能上学.I'll let you know as soon as he come back.他一回来我就告诉你.定语从句相当于形容词,用来修饰名词或代词.宾语从句相当于一个宾语,用作名词.状语从句相当于句子中的一个状语,或副词,指时间、地点和原因等.虽然它们意义不同,但用法大致相同,都要用陈述语序,都要有连接词

这个句子是强调句,但答案是BD,where
这是 简单回答 省略了 句子的其他成分
原句=it was on the farm where we worked that i got to know her.

This is the watch which i am looking for
the man who you talked with just now is my neighbour
this is the reason that he explained to me

宾语从句
一、宾语从句概说 宾语从句是在复合句中起宾语作用的从句. 在谓语动词, 介词和某些形容词等后面都可以接宾 语从句. 同学们要掌握好宾语从句,主要应该注意以下三个关键：
1．连接词：根据从句类型而定.
2．语序：用陈述句语序.
3．时态：根据主句中谓语动词的时态而定.（自然、科学规律及真理可以除外）
二、宾语从句的连接词： 宾语从句的连接词：
1． that that 引导陈述意义的宾语从句,无实际意思,在从句中也不充当任何成分.在口语和非正式文 体中 that 常被省略. She said that she missed us very much.她说她非常想念我们. I think she is right.我认为她是对的（that 被省略）
2． whether, if： whether 与 if 引导选择意义的宾语从句,意思为"是否". I wonder whether/ if she still lives here after so many years. 这不知道经过这么之年她是否还住在这里. Have you found out whether/if he is in London?你弄清楚他是否在伦敦了吗?
3． what, who, whom, which 这是一组连接代词,引导疑问意义的宾语从句. Can you tell me what bread is made from?你能告诉我面包是由什么制造的吗? I can't remember who has come to my office.我不记得谁来过我的办公室了. Tom asked me whom/who they were talking about.汤姆问我他们在谈论谁. I want to know which is better.我想知道哪一个更好些. whom 引导宾语从句时一般可由 who 替换,但如果宾语从句的介词提前,则只能用 whom,不 能用 who. I wonder with who she is angry.（×） I wonder with whom she is angry.我不知道她在跟谁生气.
4． when, where, why, how 这是一组连接副词,引导疑问意义的宾语从句. I'm not sure when he will be back.我不能肯定他何时回来. I can't tell you where he lives.我不能告诉你他住在哪儿. We don't know why he broke the window.我们不知道他为何打破窗户. Would you please tell me how I can get to the nearest bus stop? 请告诉我如何才能到达最近的公共汽车站好吗?
5．某些形容词如 afraid, sure, glad, happy 等后也可以带宾语从句（也有人认为是状语从句）. I'm afraid (that) we can't get there on time.恐怕我们不能准时到达那里了. He's not sure whether he can find her.他不能肯定他是否能够找到她.
三、宾语从句的时态： 宾语从句的时态： 宾语从句的时态原则上应与主句的时态保持一致.
1． 如果主句是现在时态（包括一般现在时,现在进行时和现在完成时）,宾语从句可以是实 际需要的任何时态. I am wondering whether he has come or not.我不知道他是否已经来了.（现在完成时） Please tell me when we'll have the meeting.请告诉我什么时候开会.（一般将来时） I don't know who they are talking about.我不知道他们正在谈论谁.（现在进行时） I have heard the window was broken by John.我已经听说窗户是被约翰打破的.
2． 如果主句是过去的时态（包括一般过去时,过去进行时）,宾语从句必须选用过去的某一 时态（即一般过去时,过去将来时,过去进行时或过去完成时等） He said he would kill her.他说他会杀了她.（过去将来时） She told us Lucy had returned home.她告诉我们露茜已经回家去了.（过去完成时） Mary was wondering who could answer the question. 玛丽想知道谁能回答这一问题.（一般过去时） I didn't tell them where you were having the meeting. 我没有告诉他们你们正在哪儿开会.（过去进行时）
3． 如果宾语从句表示的是科学其理、客观事实或格言警句等,则不管这句是何种时态,从句 一律用一般现在时. Granny told me that the earth moves around the sun.奶奶告诉我地球围绕太阳转. She said a friend in need is a friend indeed.她说患难朋友才是真正的朋友.
四、宾语从句的语序： 宾语从句的语序： 宾语从句的语序一律使用陈述语序.
1． 当宾语从句原为陈述句时,用 that 引导,语序不变.（注意时态的一致）
Tom isn't a good student. (The teacher told us) The teacher told us Tom wasn't a good student.老师告诉我们汤姆不是一个好学生.
He has given up smoking. (She said) She said he had given up smoking.她说他已经戒烟了.
2． 当宾语从句原为一般疑问句时,用 whether 或 if 连接,语序变为陈述语序.
Is Jim a doctor? (I wonder) I wonder whether Jim is a doctor.我想知道吉姆是否是个医生.
Does she dance well? (Can you tell me) Can you tell me if she dances well? 你能告诉我她舞跳的是否好吗?
3． 当宾语从句原为特殊疑问句时,特殊疑问词即为连接词,语序变为陈述语序.
Where are you going? (She asked me) She asked me where you were going.她问我你去哪里.
What does he want to do. (She wondered) She wondered what he wanted to do.她不知道他想干什么.

定语从句专题
一、什么是定语从句? 定语从句（Attributive Clauses）在句中做定语,修饰一个名词或代词,被修饰的名词,词组或 代词即先行词.定语从句通常出现在先行词之后,由关系词（关系代词或关系副词）引出. 关系代词有：who, whom, whose, that, which 等. 关系副词有：when, where, why 等. 初中阶段我们仅仅要求学生能够认识,并且正确翻译由关系代词 that, which, who 等引导的 定语从句.
请观察下面的句子：
This is the mountain village which I visited last year. 在这句话中,mountain village 为先行词,which 为关系代词,关系代词其实就是先行词的化 身,它在从句中充当主语或者宾语.所以以上的句子可以被翻译成： 这是我去年访问过的山村. 这是我去年访问过的山村. 这句话的主干是“This is the mountain village.”这是那个小山村. 从句部分是 “which I visited last year”,看上去这句话是缺少宾语的,实际上关系代词 which 就是宾语,它既是从句的引导词,又是宾语.
请看下面的句子：
He is the person who helped me with my homework last week.
翻译成： 他是上周帮助我做功课的那个人. 主句部分是“He is the person” 从句部分是“who helped me with my homework last week” 看上去,这个从句是缺少主语的,实际上,从句的主语就是 who,他跟在先行词后面,代表 先行词,在从句中充当主语.
二、关系代词：that, which, who.
1. 首先：在定语从句中所有的关系代词和关系副词都是先行词的化身,在翻译的时候,不 参照他们本身疑问副词,疑问代词的意思,如： I am looking for the photos which you took in Australia. 我正在找你在澳大利亚拍的照片. 这里的 which 代表照片,并不翻译成“哪一个”,再如 He is the photographer who won the photo competition last time. 他就是那个赢得上次摄影比赛冠军的摄影师. 这里的 who 代表 photographer,也不翻译成“谁”
2. 其次：（1）who 前面的先行词一定是人物： I got some great shots of the boy who plays the guitar on the left. 我给左边弹吉他的男孩照了一些不错的相片. 这里的先行词是 the boy,是人,所以关系代词用 who,当然用 that 也可以
（2）which 前面的先行词一定是事物： It is a band which gets everyone dancing. 这是一支能让每个人都舞动起来的乐队. 这句话的先行词是 a band,不是人,是乐队,所以用 which,也可以用 that.
（3）that 前面的先行词既可以是人,也可以是物. 注意：这并不代表 that 是万能的关系代词,到高中的时候我们就会学到,在某些定语从句, 尤其是非限定性定语从句中,我们是不能使用 that 的,但是我们在初中阶段并不要求.
3. 定语从句关系代词的省略： 与许多其它从句一样,定语从句的引导词 – 关系代词也是可以省略的,但是省略是需要条 件的,就是当关系代词在从句中充当宾语的时候,关系代词可以省略. ,就是当关系代词在从句中充当宾语的时候,关系代词可以省略. 重点有两个：第一就是从句中 从句中,所以我们要分清什么是主句,什么是从句,如： 从句中 I'll never forget the days which I spent in the countryside. 我永远都忘不了我在乡下的日子. 在这句话里,I will never forget the days.是主句,which I spent in the countryside 是从句,再 看：
Please show me the book which you bought yesterday. 请给我看一眼你昨天买的书. 在这句话里面,Please show me the book 是主句,which you bought yesterday 是从句. 第二个重点就是充当宾语： 充当宾语： 充当宾语 He is the person who talked to me last time. 他是上次和我说话的那个人. 在这句话中,关系代词 who 作为 the person 的化身,在从句中充当主语. He is the person who I met last time. 他是我上次遇见的那个人. 在这句话中,关系代词 who 作为 the person 的化身在从句中充当宾语,这个 who 可以省略. 判断关系代词充当主语还是宾语可以看它后面是否紧跟谓语动词, 如果紧跟谓语动词 （如第 一句）,则关系代词为主语,不能省略；若反之,其后没有紧跟谓语动词,而是名词（从句的主 语）,则关系代词在从句中作宾语,可以省略关系代词.
三、定语从句与宾语从句的区别： 顾名思义,定语从句是从句充当定语的复合句,宾语从句是从句充当宾语的复合句,二者迥 然不同,但是在使用中,同学们总是容易混淆这两个句型.请从以下几点区分：
（1）通过从句的位置：定语从句的位置在名词代词的后面（先行词一般是由名词或者代词 充当的）.宾语从句的位置一般在动词或者介词短语之后,因为宾语一般都在动词或者介词短语 之后. 请判断下面句子是定语从句还是宾语从句： I don’t know what you are talking about. He is angry with what you said. The tall boy who you met just now is my brother. 经过判断,前两句是宾语从句,第三句是定语从句.
（2）通过引导词：定语从句的关系代词只有 that, who, which, whom,whose 关系副词也只有 when, where, why,所以如果有的句子是 whether, if, how, what 等词引导的,肯定不是定语从句.
（3）通过从句的成分：都是 that 引导的从句,宾语从句和定语从句也有的区别,我们可以 通过 that 在从句中充当的句子成分判断,如： I know that you are right. 我知道你是对的. 这是一个宾语从句,that 引导的宾语从句,that 只是连接词,不充当任何成分,所以 that 后 面的句子 you are right 是一个主语谓语完全的句子. He is the person that I am looking for.这是一个定语从句,that 在从句中充当 look for 的宾语, 所以看上去 look for 是没有宾语的.

这句不是定语从句 而是同位语从句
只能用that
which不能在同位语从句中使用
要判断是定语从句还是同位语从句就要看that是否在从句中做一定成分

which makes everyone surprised.

选择A,在那个剧场,我们将能拜访一位知名的钢琴家.
在那里,所以用in which

我简单地回答,不明白再问吧.
宾语从句：my teacher said that we should finish our homework first.
主语+谓语动词+that从句作为宾语
定语从句：he is an old man who has a little dog.
句子成分齐全he is an old man；先行词是man,引导词是who,who 引导的定语从句是修饰man,告诉我们这个man是有着一条小狗的man.
根据先行词的不同,还可以用that,which,where等词引导.
状语从句：i will go to the park,when it stops raining.
状语一般是说明时间、地点、条件、原因、目的等

The man is famous that his picture is in the newspaper.

all、最高级、the one等都是针对whichthat两个词的比较.先行词出现以上几种的话,只能用that而不能用which.

第一个句子,医生强烈建议Vera,that后跟的是advise的宾语从句.建议后的宾从要用should+动词原形,当然should也可以省略.重要的是,在最后一个分句中有连词but,所以用it做主语,代替前面所提到的内容.如果最后的分句中没有but,而又有逗号,这个题就要用which了.
第二个句子,就是简单的,women后的句子是个完整的,有主谓宾,就是缺的状语.根据前面的chairs,可是判断是地点状语,所以这个题,要用where来引导.
不知这样的回答是否满意?

差别在于这个从句在整个句子中充当的成分,做什么成分就叫什么从句.关系词或代词的作用就是引导这些从句.
主语从句 充当 主语成分,如：（What caused the accident） remains unknown.其中What caused the accident就是主语从句.
最常见的主语从句是形式主语it句型,如It is certain that he will win the match.
以此类推,表语从句His suggestion is（ that we should stay calm.）
宾语从句I don’t know（ if there will be a bus any more.）
状语从句I will call you （as soon as I arrive in Beijing.）
定语从句He lives in a room （whose window faces south.）

who做主语和宾语都可以

选A
解析如下:
从句也是句子,句子结构必须完整.
从句:I'll for ever remember in my life.
"remember" 及物动词后面缺宾语,所以只能选用关系代词.故选A.
对比分析如下:
(1)
October 1,2003 is the day "that/which "I'll for ever remember in my life.
(2)
October 1,2003 is the day "on which/when " I'll for ever remember "you" in my life.

定语　　定语用来限定、修饰名词或代词,是对名词或代词起修饰、限定作用的词、短语（动词不定式短语、动名词表示的）汉语中常用“……的”表示.主要由形容词担任,此外,名词、代词、数词、分词、副词、不定式以及介词短语也可以来担任,也可以由一个句子来担任.单词作定语时通常放在它所修饰的词之前,作前置定语.短语、从句作定语时则放在所修饰的词之后,作后置定语.
被定语从句修饰的名词、代词称为先行词.如“The man”、“The book”.如“那个穿着西装的人是我爸爸” 这就是一个定语从句.
代词引导的定语从句
关系代词所代替的先行词是人或物的名词或代词,并在从句中充当主语、宾语、定语等成分.关系代词在定语从句中作主词保持一致.1,who, whom, that　　这些词代替指人,“whom”作宾语指人,"who"和“that”既可作主语又可作宾语（作宾语可以省略）,可以指人也可以指物.在从句中所起作用如下：
（1）Is he the man who/that wants to see you? 他是那个想见你的男人吗?（who/that在从句中作主语）
（2）He is the man （whom/that） I saw yesterday. 他就是我昨天见的那个人.（whom/that在从句中作宾语）
（3）The man whom you spoke to just now is our English teacher. 你刚刚说话的那个男人是我们的英语老师.（whom在从句中作宾语）
注：who在定语从句中指人,作主语和宾语,作宾语时可省略；whom在定语从句中指人,做及物动词或介词的宾语,可省略.2,which、that 用来指物　　(用作主语、宾语,作宾语时可以省略）,例如：
（1）The prosperity which/that had never appeared before took on in the countryside.农村出现了前所未有的繁荣.（which/that在从句中作主语）
（2）The package (which/that) you are carryingis about to come unwrapped.你拿那个包裹快要散开了.（which/that在从句中作宾语）
注：which在定语从句中指物,可作主语或及物动词或介词的宾语,作宾语时可省略；that在定语从句中既可指人又可指物,在定语从句中作主语、宾语和表语,作宾语时可省略,指人时,相当于who或whom,指物时,相当于which,作介词宾语时,介词不可提到that前,当介词提前时,需要用which或whom来代替.[1]3.whose　　(只用作定语)
“whose”表示谁（可以为人也可以为物）的（东西）
关系代词：在句中作主语、宾语或定语.
1. that既可代表事物也可代表人,“which”代表事物；它们在从句中作主语或宾语,作宾语可省略“that”在从句中作宾语时常可省略关系词,“which”在从省略.[eg：This is the book （which）you want.]
2. 不及物动词+介词”的介词的宾语代词“wh”放在它原来的位置.
3. 代表物时多这时的that常被省略；
c）被形容词最高级修饰时；既有人又有物时；
e）整个句中前面已有“which”,“wh”行
关系副词：在句中作状语
关系副词=介词+关系代词
why=for which
where=in/ at/ on which（介词同先行词搭配）
when=during/ on/ in/…… which（介词同先行词搭配）
1. “where”是关系代词,当然也不用“that”引导.
By the time when you arrived in London, we had stayed there for two weeks. 到你到达伦敦的时候,我们在那里已经待了两个星期.
I still remember the place where I met her for the first time. 我仍然记得我第一次见到她的地方.
Each time when he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc. 他每次出差都带来了生活必需品,如毛巾,肥皂,牙刷等其他东西.
2. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用“there is”开头.
There is somebody here who wants to talk to you. 这里有人要和你说话.
分作进一步说明,通常是引导词和先行词之间用逗号隔开,将从句拿掉后其他部分仍可成立.
编辑本段关系副词的用法及说明关系副词why　　关系副词why主要用于修饰表示原因的名词（主要是the reason）,同时它在定语从句中用作原因状语.如：
We don’t know the reason why he didn’t show up. 我们不知道他为什么没有来.
She didn’t tell me the reason why she refused the offer. 她没跟我讲她拒绝这项工作的原因.
与关系副词when和where不同,why可以换成that或省略.如：
That’s one of the reasons (why, that) I asked you to come. 这就是我请你来的原因之一.
另外,与关系副词when和where可以引导非限制性定语从句不一样,why只能引导限制性定语从句,不能引导非限制性定语从句.如：
他失去工作的主要原因是他喝酒.
误：The main reason, why he lost his job, was that he drank.
正：The main reason why he lost his job was that he drank.关系副词when　　关系副词when主要用于修饰表示时间的名词,同时它在定语从句中用作时间状语.如：
There comes a time when you have to make a choice. 你必须作出抉择的时候到了.
Gone are the days when they could do what they liked. 他们为所欲为的日子一去不复返了.
We’ll put off the picnic until next week, when the weather may be better. 我们将把野餐推迟到下星期,那时天气可能会好一点.
注意不要一见到先行词为时间名词,就以为一定要用关系副词when来引导定语从句,同时还要看它在定语从句中充当什么成分——如果在定语从句中用作时间状语,就用when；如果在定语从句中不是用作时间状语,而是用作主语或宾语,那就不能用when,而要用that, which等.如：
Don’t forget the time (that, which) I’ve told you. 不要忘记我告诉你的时间.
关系代词that / which在定语从句中用作动词told的宾语,正因为是用作宾语,所以也可以省略.关系副词where　　关系副词where主要用于修饰表示地点的名词,同时它在定语从句中用作地点状语.
与前面when的情况一样,注意不要一见到先行词为地点名词,就以为一定要用关系副词where来引导定语从句,同时还要看它在定语从句中充当什么成分——如果在定语从句中用作地点状语,就用where；如果在定语从句中不是用作地点状语,而是用作主语或宾语,那就不能用where,而要用that, which等
关系代词that / which在定语从句中用作主语.
另外注意,where有时还可用于抽象名词后引导定语从句.
一份整天坐办公桌前的工作.
非限制性定语从句　　意义：
非限制性定语从句起补充说明作用,缺少也不会影响全句的理解.在非限制性定语从句的前面往往有逗号隔开,
3. 非限定性定语从句可将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数,
4. 有时as也可用作关系代词
5. 在非限定性定语从句中,不能用于在从句中做主语
whom指人　　注意：关系代词“whom”在口语和非正式语体中常用“who”代替,可省略.
如果在从句中做宾语,就用“whom”或“who”.
which 、that 通常指人也可指物　　在定语从句中做定语,表所有.
“whose”指物时通常以以下结构来代替：
that指人时　　相当于“who”或者“whom”；指物时,相当于“which”当前头有最高级序数词“all”不定代词时必须用“that”.
在定语从句中做主语、表语或者宾语,做宾语时可省略.
when指时间　　在定语从句中做时间状语也可做连接词用.
介词和关系代词　　1）介词后面的关系代词不能省略.
2）“that”前“Do you”作介词的宾语,且可以省略.例如：
（1）The school（that/which）he once studied in is very famous.“that/which”可以省略.
= The school in which he once studied is very famous.“which”不可省略.
（2）Tomorrow I will bring here 用,如：look for, look after, take care of等.
T This is the watch which/that I am looking for.（T=正确）
F This is the watch for which I am looking.（F=错误）
2. 若介词放在关系代词前,关系代词指人时用“whom”,不可用“who”或者“that”；指物时用“which”,不能用“that”；关系代词是所有格时用“whose”
（1）The man with whom you talked is my friend.（T）
The man famous.
（2）I bought many books yesterday, three of which are written by Lu Xun.关系代词　　关系代词（一般情况下）“that”可用在从句做主语,谓动词的宾语,但是不能做介词的宾语.
“which”指物,在从句句中作主语；
“whom”在从句中作宾语；
“why”在从句中修语,先行词通常是“the reason”；
有时“why”也可用“for+which”代替.
例：A doctor who looks after people's health.
主语 谓语 先行词 定语从句修饰先行词判断介词和关系代词　　方法一： 用关系代词,还是关系副词完全取决于从句中的谓语动词.不及物动词后面无宾语,就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语,则要求用关系代词.例如：　This is the mountain village where I stayed last year.
判断改错:
（错） This is the mountain village where I visited last year.　（错） I will never forget the days when I spent in the countryside.　（对） This is the mountain village (which) I visited last year.　（对） I'll never forget the days (which) I spent in the countryside.
例. Is this the museum ____ the exhibition was held?
A. where　B. that　C. on which　D. the one
,解析： 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因 in the museum词组,可用介词in + which 引导地点状语.而此题中,介词on 用的不对,所以选A.
关系词的选择依据在从句中所做的成分,先行词在从句中做主、宾语时,选择关系代词（who, whom, that, which, whose）；
先行词在从句中做状语时,应选择关系副词（“where”地点状语,“when”时间状语,“why”原因状语）.
编辑本段关系词的选择只用that不用which　　1）当先行词是或被序数词,最高级,不定代词修饰时,关系词用that不用which.
2）当先行词既有人又有物时,用that.
3）当先行词带有the only,the very,the same,the last,the one等词时,用that不用which.
4）当主句中有who或which时,为避免重复用that.
5）当先行词是形容词最高级或被形容词最高级修饰时 只能用that只用who不用that　　1）如果先行词是those,they,all,persons,people,he,anyone,one时用who不用that.
2）当先行词指人并含有较长的后置定语从句或在被分割的定语从句中时.只用which不用that　　1）当主句先行词后有介词时,用which.This the one of which I'm speaking.
2）非限定性定语从句,用which.
3) 描述句中一般用which.Beijing,which was China‘s capital for more than 800years.
4）those +复数名词之后,多用which .Shopkeeper want to keep a number of those goods which sell best.
5）先行词本身是that时.注意　　1）there be句型中,指人用who指物用that.2）当主句中缺少主语或表语时,用the one.
2）当出现先行词+介词时,关系词只能用whom或which
编辑本段先行词和关系词　　1）Whoever spits in public will be punished here.（“Whoever”可以用“anyone who”代替）
2）The parents will use what they have to send their son to technical school. （“what”可以用“all that”代替）
但这两句句子已经不是定语从句了,是名词性从句.因为定语从句一定要有先行词,而名词性从句没有.将“Whoever”、“what”分别用“Anyone who”、“all that”代替后,才是定语从句,先行词分别是“Anyone”、“all”.An invitation from her boss, ___came as a surprise.
A. it　B. that　C. which　D. he
答案C.
此为非限定性从句,不能用“that”修饰,而用“which”、“it”和“he”都使后句成为句子,两个独立的句子不能单以逗号连接.况且选“he”句意不通.
2）The weather turned out to be very good, ___ was more than we could expect.
A. what　B. which　C. that　D. it
答案B
英语语法上行不通.
3）It rained hard yesterday, ____ prevented me from going to the park.
A. that　B. which　C. as　D. it
答案B
“as”和“which”在引导非限宾语.但不同之处主要有两点：
（1）importance to me, as my own is.
在一定的语言环境里,有些名词可以具有形容词的性质.这些名词主要是那些表示人的身份、职业、状态的名词.值得一提的是,在这些具有形容词性质的名词之后,引导定语从句的关系代词不能用“who / whom”.
（2）动词短语先行成分.
这种动词短语既可是限定形式也可是非限定形式.如果是动态动词短语,它们在从句中就一般有限定或非限定形式的替代动词“do”和“as / which”一起代替.“do”可以出现,也可以不出现,但不能用其它动词代替.
（3）句子作先行成分.
这句子可以是整个主句也可以只是主句中的一个从句.有时是连续几个句子,有时甚至可以是一个完整的故事.
二、“as/which”特殊定语从句在句中的位置.
由于先行成分的构成成分”特殊定语从句在句中的位置有以下几种情况：
1. 形容词做先行成分时：形容质的which”特殊定语从句置于先行成分之后.
2. 动词词短语作先行成分时,“as / which”特殊定语从句置于先行成分之后.但是,当从句中含有表示主观意志的插入成分时,“as”特殊.
3. 句子作先行成分时：“as”特殊定语从句的位置较灵活,可以置于先行成分之前、之中或之后.但如果先行成分是直接引语,“as”特殊定“s”特殊定语从句与否定词的相对中则常用一些表示“合乎自然规律”、“众所周知”或“经常发生”等意义的词语,如natural, known to all, usual等.
4. 有无状语意要是方式状语意义,而“which”特殊定语从句则无状语意义.“as”特殊定四、关系代词“as”与“which”一词.如：
Freddie, as might be expected, was attending the conference.
1). “Which”作主语时,谓语动词不限,主动被动皆可,只是谓语动词为被动语态时助动词“be”省略.
2). “as”和“which”都可以在特殊定语从句中宾语.
3). “as”和“which”在特殊从句中作补语.如：
We thought him a gentleman, as/which he could never be.
“as”特殊定语从句中可以主谓倒装,“which”从句中则不能主谓倒装.
如果先行成分不是主语补语或宾语补语,关系代词用“which”而不用“as”.如：
He talked like a native, which/as he hardly was.
5."as"用法：
1)."as"引导限制性定语从句
a."such.as"
He is not such a fool as he looks.
I have never heard such a story as he tells.
b."the same .as"
This is the same book as I lost last week.
(区分"the same...as"与"the same.that"：两者都引导定语从句.that从句中说明的名词与the same修饰的名词是同一个.as从句中说明的名词与the same修饰的名词是同一类,而非同一个.举例：①This is the same pen that I lost. 这支钢笔就是我丢的那一支.②This is the same pen as I lost. 这支钢笔跟我丢的那支笔一模一样.)
c."as...as"
As many children as came were given some cakes.
2)."as"引导非限制性定语从句
常用句式:as is said above 综上所述
as is known to all 众所周知
as is often the case 通常如此
as is reported in the newspaper 如报纸所报道的
6. “which”在特殊从定法
（1）不用that的情况
（a）在引导非限定性定语从句时.
（错）The tree, which is four hundred years old, Is very famous here.
（b）介词后不能用.
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.
（2）只能用“that”作为定语如“last,just”修饰时,只用“that”.
（d）先行词为序数词、数容词,又有物时.
（f）先行词指物,在主句中作是“the way”或“the reason”时,“that”可作关系副词,也可省略.
（h）主句的主语是疑问词“who /which”时,避免重复要用“that”．
举例：
Is this the book that you borrowed in the library?
这是你在图书馆借的书吗?
Who that break the window should be punished．
谁打碎了窗户谁该受罚.
All that is needed is a supply of oil.
所需的everything that he had stolen to the police.
那贼最终把偷的全部东西交给了警察.
定语从句只能“that”引导的情况：
1、先行词是最高级或被最高级修饰.
This is the most interesting book that l have ever read.
2、先行词是序数词或被序数词修饰.
The second foreign country that l expect to visit is Greek.
3、先行词是不定代词时,如"all、few、little、much、anything、nothing、something"
This is the very good dictionary that I want to buy.
4.、先行词既有人又有物时
Can you remember the scientist and his theory that we have learned?
5、先行词被only”、“the every”、“no”、“one of”等修饰
He is the only person that l want to talk to.
6、在以“which”、“who”、“whom” 引起的问句中,为避免重复,常用"that"
Who is the man that is standing there? Which is the T-shirt that fits me most?
7、“there be”句型中
8、先行词在主句中作表语,或者关系代词本身作从句的表语时宜用“that”
“that”在作宾语时可省略.
（五）区分定语从句和同位语从句
1、定语从句修饰先行词,它和先行词是修饰关系；
同位语从句说明先行词的具体内容,是补充说明的关系.
（1）The planeis clear. 同位语从句
2、定语从句由关系代for advice.
（3）The fact that the moon moves around the earth is known to all.
（4）The fact is that the moon moves around the earth.
[定语从句]介词+关系词
1）介词后面的关系副词不能省略.
2）“that”前不能有介词.
3）某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词“when”和“where”互换.例如：
This is the house in which I lived two years ago. 这是我两年前住过的房子.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?
Do you remember the day when you joined our club?

答案不选C
应该是A．that followed
B．to follow表示将来的几天
C.应写成following days
D．followed that不能省略

A.
我为印度人对他们的自然资源的限制利用而感动.
make use of...利用.

他们试图想出一个能够提前完成任务的计划.
by是介词,关系代词紧跟在介词之后时,不能用that,指物时只能用which,指人时只能用whom.而且不能省略.
但如果介词移到后面,则可以用that.而且,由于介词后面的成分叫宾语,关系代词作宾语时,只要不是紧跟在介词之后就可以省略.
上例可以说成：
They tried to think of a plan which/that they could fulfil their task by ahead of time.
或They tried to think of a plan they could fulfil their task by ahead of time.

the A and B which修饰A和B(因为A和B同属于the定冠词下,看做一个整体）
the A and the B which 修饰B（因为A和B是并列的,此时按照就近原则修饰B）
A and B which（同上）
A and the B which 修饰B.
后三者应该是一样的,唯独第一个特殊.

1.I still remember the days ___we spent together.
that/which/不填.指物的关系代词that和which都可以.作宾语的关系代词也可以省略.
2.I sill remember the days __we worked together .
when关系副词,定语从句中作状语.也可以填duing which
3.That is the factory ____his father once worked.
where关系副词,在定语从句中作状语.也可以填in which
4.This is the reason ___he told me yesterday.
that/which/不填.关系代词在定语从句中作直接宾语.

The room in which we took the photo was very dirty.
第二句后半句怎么和第一句一样?弄错啦?
This is the pen with which I wrote the letter
He lived in a big house where a tall tree stood in front of it
I'll never forget the day on which I first met him
The two things which they felt proud of were Jim's gold watch and Della's hair
The man who you spoke to just now is a relative of mine

第一句因为有first修饰所以必须用that,第二句the only修饰时用that或who都可以.
希望能帮到你.

这里which引导定语从句,修饰coat（coat是先行词
然后which在从句which has to survive at high altitudes充当主语

正确答案是：
1.The story which/that was told by the famous writer was very long.
2.English is a language that/which is widely used in business.
3.The man who made a lot of money did not know what to do with his money.
4.Chinese is a language which/that is spoken by about 1/5 of the world's population.
5.The boy who did not obey the traffic rules was killed in a road accident.
6.The mystery that/which has puzzled a lot of people is still unsolved.(你的单词抄错了)
7.An international language which/that can be understood and used by everyone in the world has not yet been found .(意思是：能被世界上每个人能明白和运用的国际语言还没找到)
8.Anyone who lives in this city long enough can tell you where the zoo is.
定语从句能补充描述你所要表达的事情,是内容更为详实,是常用的一种句型.连接代词指物、指事时,可以用that,which.但是指人只能用who/whom（宾语）.,
你还是做对了一些,不错啊.加油!希望有帮到你哟!

首先,确定是定语从句,就不能选what了（为什么别问我,基本语法）.
然后来分析从句的结构,从place往后就是从句.先行词是place,做主句的宾语,因此应该选择一个关系代词.同时,XX considered itself.证明这个引导词要做从句的主语,因此不能选where（这是副词,不能做主语）.
对于B和C两个关系代词,一般有这样的习惯,如果先行词有唯一性、专有性、特殊性的修饰,一般都要选that,而不用which.

2.The way they talked ________ the problem seemed impossible.
A.about settling B.to settle C.of settling D.about to settle
因为前面是the way 应该是the way to do sth 表示一种目的
5.The school _______ I studied ten years ago is ______ we visited yesterday
A.where,that B.that ,which C.where,the one D.which,that

6.Edison made a lot of inventions,______ of great importance.
A.which I think are B.which I think they are
C.which I think they D.I think which are
应该选A 非限制性定语从句~d肯定是错的 而且b c中不能有THEY 因为which已经带指they !
7.It might be I ,who______ caused the accident,who_____ to answer for it.
A.has,are B.have,are C.have,is D.have,am
为什么选C不选B
I是单数阿 所以用单数 而且前面是It might be ...所以这个BE应该用is
11.The Greens will move into the new house next Monday,______ it will be completely finished.
A.by the time B.by which time C.by that time D.by this time
为什么选B不选C
非限制性定语从句 因为by是介词 后面不能加that 这个你记住就好了~!
还有 ,后面也不能用that
18.Will you please show me the way to the only tall building ______ stands near the post office?
A./ B.in which C.that D.where
为什么选C不选D
这里的定语修饰的是building 所以是哪一个building 显然where是错误的 the only 和 比较及修饰的名词 后面的定语从句的先行词只能用that 不能用which 其实可以直观的理解嘛 只有一个不就不能用哪一个（which）了~
21.With the fast development of agriculture ,the people _____ village I taught before have a happy life.
