关系词是不是代替先行词的代词?

主格：i,you,he,she,it,we,you,they
宾格：me,you,him,her,it,us,you,them
形容词性物主代词my,your,his,her,its,our,their
名词性物主代词 mine,yours,his,hers,ours,theirs
看的出来,主格是做主语,宾格是充当宾语的形势
如i love you用i而不用me的原因是i充当主语,反过来you love me这个时候就只能用me而不用il额
所有格是主要是加在名词前,表示名词的所有形式.
如your pen你的钢笔 your lovers~
所以最简单的寄发是主格做主语,宾格做宾语,所有格放在名词前,表示他的所有者!答案补充主格就是人称代词做主语,宾格是人称代词做宾语时所用的代词形式.所有格就是修饰名词时,代词的形式统称为所有格.因此,他的定义也就决定了他的用法啊.当你做主语时,就只能用主格啊,作宾语就只能用宾格,修饰名词时只能用所有格了

先行词在定语从句中作介词in的宾语.
his girl friend played the leading role in the film.

who~~~~~~~~~~

说实话这个一直不好分.
并不是一定要或一定不要.
一般都是看习惯用法,要慢慢掌握.
或者你可以看看那个介词是跟动词关系更紧密一些还是跟名词关系后紧密 联系更近的放在一起 但是这样说很不好分 所以还是慢慢积累或凭语感.

此处的somewhere就是关系副词即引导词,在主句中充当不定代词,所以要加 to.与whoever,whatever等一样,前面可以不用先行词的.

efore
in

求采纳
先行词是the houses
关系词是which/that,此处被省略了

1.about which
2.for which
3.on which
4.in which
5.about which
6.in which
7.to whom
8.with which
9.on which
10.of which
11.for which
12.on which
13.without which
14.at which
15.with whom
16.from whom
17.on which
18.on which
19.out which
20.at which

因为介词后面只能用which啊
which 代表物,作从句的主语,宾语,可引导非限制性和限制性定语从句
that 代表人或物,作从句的主语,宾语,表语,只引导限制性定语从句
只用which
1 关系代词作介词宾语,即 介词+关系代词,指物只能用which
Last night I had a dream in which I became a Nobel Prize winner.
2 非限制定语从句中,指物只能用which,亦可指整个前面的句子.
He reads English every day,which does good to his English study.
只用that
1 先行词为不定代词:one much everything all any ...
2 先行词被形容词最高级所修饰
3 先行词被序数词所修饰
4 先行词由only ,just ,very,right等修饰
5 在以which 开头的特殊疑问举重,避免重复用that.
6 先行词在从句中担任表语,从句的关系词用that.
够了咩?

1.There is something that I can't tell you.
2.There are some people that you don't know.
3.There will be a gift for you that you can never know what it is.

用that 这只能说是语法书里的概念了 ： 当先行词有the very，the only ,the same ,any,few,little,no,all,one of 等次修饰时应用。
你说的（3）和（4）也是对的 但是当这些先行词前有上述所说词修饰时就改用that了。
LiMing is the only one that wants to be a teacher 懂了。 你说的先行词是people 而people前又用all ，所以要用that了

关系词在定语从句中不一定要做成分.
这个从句只要是做整个句子的定语就叫定语从句.这是定语从句的概念.
你的例句中of mine from when i was born showed up 做good friend 的后置定语
望采纳

e.g :I go to school by bike.
by 就是介词,一般用于表地点,时间,条件等状语的前面,当然也有特殊.关系词分关系代词和关系副词,用于引导一个或几个宾语从句.
e.g :I like music that I can sing along with.
这里,music 是先行词,that 就是关系代词.

可以省略,补上应该是：in which/that（副词）,这是口语中经常省略.

ook是先行词,关系词which做主语
pen先行词,关系词that做宾语
one先行词,关系词that做表语
bicycle先行词,关系词whose定语
city先行词,关系词where状语

that/which
whose
that/which
that
whose
who/that
which/that
最后一句没看懂

首先你要搞清楚 focus on 的意思是 某某把注意力集中在某某上.
a research center focused on the genetics
如果用你的方法 即用语法分析的话 按照你的观点说"The center focus on the genetics"那么意思就是“研究把注意力集中在基因上”显然是错的 这儿主语应该是人
“We focus the research on the genetics”假如变换成被动语态
“The research was focused on the genetics by us"去掉"by us"就行了
所以补应该是主动语态 而是被动语态
另外一种理解方法更简单：原句子的which应该是with吧 with 复合结构你清楚吧
with+宾语+宾补 这儿你把focused理解为一个形容词：集中的
所以focused就是research的宾补 这样就能理解通
最后 做题的一条经验就是 看到focus 这种类似的词汇 我肯定选focused 因为这种词不会考你是否认识它们 而是考它们的用法 既然是用法 就只有这一种用法可以作考点.

当先行词为指人的不定代词时必用who
当先行词是指物的不定代词时必用that

It's time + that 是固定句型,that可省略,time可由high,about修饰,从句中的谓语动词有两种形式,或者用动词的过去式(be用were)；或者用shoud + 动词原形（should不能省略).此句型为虚拟语气句型,表示“现在某人该做某事了”.含有该事早该去做而未做,现在去做似乎都为时已晚的意思.

C,此题为定语从句,look forward to为固定搭配,to提到关系词之前,另外,在此处to为介词,后面要接宾语,所以要用关系代词,整句话的意思是：最后他还是从父亲那得到了他期待已久的礼物.所以应当选C
另外,在定语从句中介词后面不能用that.

关系词可以分为关系代词和关系副词.定语从句可以分为限制性定语从句和非限制性定语从句.第一,在限制性定语从句里,1、如果关系代词在从句中充当宾语,可以省略.例如：You had better review the words (that/which) you learnt yesterday.2、如果先行词在主句中充当表语,且在从该剧中也从当表语时,可以省略.例如：The city is not the one (that ) it was years ago.3、先行词the place、the reason、the way后面的关系副词可以省略.例如：This is the place (where) we first met years ago.第二、在非限制性定语从句里,即使that在从句中充当宾语,也不能省略.

由于居里夫人有坚定执着,为科学献身的精神,因此她完成了一项伟大的自然发现,也完成了对人生意义的发现.

需要提醒的是,anything, something等后面的形容词从句通常都用that引导,但偶尔也可用which替代that.
如：We have proved that anything which exists is real./ If you have something to say which is on the subject, wait till you have a chance and say it to the whole class. 所以选D是对的.

首先定语从句限定性定语从句和非限定性之别;其次在限定性定语从句中,先行词和关系词基本是连在一起的,关系词也充当句子的成分;在非限定性定语从句中,一定有逗号隔开的,这个定语从句是对整个句子的补充说明,没有句子也是完整的.

其实 只是两种不同的表达法而已,
The students （who are different in character )are quiet similar in their interests .
这是用定语从句作定语,修饰 The students .
The students （ different in character )are quiet similar in their interests
这个句子只是形容词短语作后置定语,同样也是修饰The students .
表达形式不同,但意思完全一样.

The family who have the cars are from china.
根据谓语动词have可以判断,family并不是指家庭,而是指家人.
先行词是人,关系代词用who.

原则：定语从句关系词的选择是根据先行词在从句中所作的成分来决定的.
where用在关系词在从句中做状语的情况,而that/which则在从句中起名词性作用.
举例：I want to go to Beijing where I can visit some places of interest.where在从句中做地点状语,指代in Beijing.
I want to go to Beijing in which I can visit some places of interest.which在从句中作in的宾语,构成介宾短语,整个介宾短语作状语.
I want to go to Beijing which/that is the capital of China.which/that在从句中作主语,指代Beijing.
不懂追问.

不一定,time 也有很多意思
比如:I miss the time when we were together.
It's the second time that I have seen the picture.
第一句中time表示"时间,时候",第二句time就表示"次"

That(指物)和those(指人或物)可做定语从句的先行词,this和these不可做先行词,those做定语从句先行词时,当其指物关系词用that/which等,当其指人时,关系词用who等,具体示例如下：
He admired those who looked beautiful.他很喜欢那些看上去很美的人.（指人）
He admired those which looked beautiful.他很喜欢那些看上去很美的东西.（指物）
(错)He admired that who danced well.（that不能指人）
(对)He admired those who danced well.他赞赏跳舞好的人.（those可指人）

先行词是定语从句的引导词前面的被定语从句所修饰的名词、代词。在定语从句中充当一定的成分。之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。

这里的 visit作不及物动词用的,意思为“访问,参观,游览,逗留”等.
这句话表达的意思是这样的：
I have ever visited in the place.大意是：我在这个地方已进行过访问（或参观）.
所以visit后面不用宾语,而需状语（ in the place）.
但visit又可以作及物动词,所以下面的表达也是正确的.
This is the place which（或that）I have ever visited.

一般来说用that,不过好像也没特别要求不能用which吧!要看具体的句子吧!先行词有only,few,little,no,all,one of等修饰的时候只能用that,不能用which.

是可以同时实现这三个作用的,用例子来说哈
Yesterday I went to the bar which we always have fun in.
关系词WHICH,我们开头的句子,同时在句中作IN 的宾语,也就是IN THE BAR.
He has a friend whose father is a doctor
WHOSE 引导（谁的---当然就是HE）的父亲是一位医生,在剧中是FATHER 的定语.WHOSE FATHER 作剧中的主语
常考的点就是定语从句和主语从句,以及强调句型.
个人来看还是语感也很重要,句子结构来说从中文着手会好一点.
中文和英文都是如此的结构
主语+谓语+宾语（主语+系动词+表语也是一样的）
定语修饰名词性结构,也就是：（定语形容词）主语+（副词）谓语+（定语形容词）宾语
当然还有状语,状语从句就很简单了哦,时间地点,条件,结果什么的,就是修饰整个句子用的

who
which
which
who
which
when
which
which
which
which
when

如果先行词是人,which是肯定不能用的,只能用who或者是that
如果前面有the only,the first等词修饰的话,就只能够用that,who就不可以了.

这句话中根本就没有定语从句或其他任何从句.这是一个简单句.

第一句是介词+关系代词which 引导定语从句,第二句是关系代词whose 引导定语从句,第二句中的it 多了,应删掉.定语从句的关系词是一定要位于从句最前面引导定语从句.

例句中 the one 是先行词,that 是关系词
在后面的定语从句中,that 做的就是表语 （was是be的变形,be 动词后就是表语）
所以这里的that 不可以用which 来替换

(1)先行词被①形容词最高级 ②序数词 ③数词几种词修饰或被 ④only、any、few、little、 no、all、one of等修饰时.
(2)先行词为all、much、little、none、few、one、something、anything等不定代词时.
(3)先行词中既有人又有物时.
He was looking pleasantly at te children and parcels that filled his bus.
(4)先行词在主句中作表语关系词在从句中作表语时.
The village is no longer the one that was 5 years ago.
(5)当主句中含有疑问词which时.
Which are the books that you bought for me
宜用which而不用that的情况
(1)在非限制性定语从句中
(2)在关系词前有介词时
(3)当先行词本身是that时
(4)当关系词离先行词较远时
关系词who与that指人时,也有不同情况分别用不同的关系词
(1)当主句是there be句型时,关系词用who.
(2)先行词是为anyone、those、someone、everyone、one等词时,关系词用who.
(3)当主句是who作疑问词时,关系词用that.
Who is that girl that is standing by the window?
(4)whom在从句中只作宾语,可被who取代.

不能省..定语从句不能滴

这个问题的关键是要注意动词词组、或其它词与介词的搭配：
1、与动词搭配‘V + prep’
He has found a good job for which he is qualified .（ qualify + 名词+ for "使…具有…资格" ）他找到了一份他能胜任的工作.
The man to whom you talked just now will chair the meeting tomorrow.（ talk to + 名词 "与某人谈话" ） 你刚才与他谈话的那个人明天主持那个会议.
He is bargaining with the landlord over the monthly price at which the apartment rents.(rent at + 表示价格的词 "某物以某价格出租" ）他在与房东就那套公寓出租的月租金进行磋商.
e.g.Where is the man whom (who,that) you gave your ticket to?
Where is the man to whom you gave your ticket?
e.g.Have you met the person about whom he was speaking?
Have you met the person (that,who) he was speaking to?
This is the man to whom I referred just now.
Do you know the person with whom she was talking?
She is the girl who(m) I’ve never heard of.
The tool with which he is working is called a hammer.
x09The tool (which / that) he is working with is called a hammer.
This is the question about which we’ve had so much discussion.
x09This is the question (which / that) we’ve had so much discussion about.
This is the way in which (that) he operates the machine.
2)与名词搭配 ‘N + prep’
They are still living in the little house in which they've been lived for 15 years.（ in the house " 在屋子里" ） ‘他们现在还住在他们已住了15年的那个小房子里.’
We've worked out a method by which our production can be raised on a large scale.( by a method通过某种方法) ‘我们已研制出了一个能大规模提高生产的方法.’
She didn't realize the extent to which she had been distracted .（ to extend "到某种程度" ）
‘她没有意识到她心烦意乱的程度.’
3)与形容词搭配 ‘adj + prep’
The secretary with whom the boss is not happy will be fired for her inefficiency .(happy with "对…表示满意") ‘老板对其不满意的那个秘书将由于她没有工作效率而被解雇.’
I've found the job for which I've been eager for a long time.（ eager for "渴望得到…" ）
‘我已找到了我渴望已久的那份工作.’
He is a learned man with whom we are familiar .
(familiar with 熟悉…) ‘他是一位我们熟悉的有学识的人.’
非限制性定语从句的用法：
At school we were greeted by the teachers,most of whom were middle aged.
I have seen many interesting films,one of which is named “Who Am ”
She had 8 children,3 of whom lived with her.

1、2、13 关系副词when 引导定从 并在定从中作时间状语
3、9、12关系代词which 引导非限制性定从 并在定从中作主语
4、5、7、22关系代词 引导定从 并在定从中作宾语
6、8关系副词where引导定从 并在定从中作地点状语
10、11关系副词where引导非限制性定从 并在定从中作地点状语 定从是倒装句
14 不是定语从句 可以 看作 强调句型 省略了for
15 对地点状语强调 的强调句型
16 对时间状语强调 的强调句型
17 19that相当于关系副词 引导定从
18about which 引导定从 并在定从中 作状语
20、21关系代词 that 引导定从 并在定从中 作主语
23 关系代词 whose引导定从 并在定从中 作定语
23of which 引导定从 并在定从中 作定语

who=the man 但是句子中的 the man是主句的主语 who 是来代替the man的

我对你提的问题也不明白,但是针对你提的问题我也有几个问题
1,如果in which 可以用的话,at which 或者 on which可不可以用,如果都可以的话,是不是就造成了混乱?
2.是谁说的只能省略,如果是教学大纲或者语法书上说的,那记得就行了,如果是网上或者是老师说的,需要求证一下.

visit是及物动词,所以这句话的从句中先行词作宾语,所以用关系代词that,如果先行词在从句中不作宾语,就用关系副词
定语从句中有最高级,something,anything,little,all这样的词,关系代词都用that是对的

从意思上说 感觉有点牵强,不过从语法上讲没有问题
The parents will use sth to send their son to technical school
而这里的sth就是what they have（做use的宾语）. 而 to send their son to technical school 与use 构成 use sth to do sth 短语
第二句里面all 就是use的宾语,that they have 是定语从句

一般来说要加关系词,例如 This is the place where he proposed to me. 这是他向我求婚的地方.主句是this is the place. 从句是he proposed to me.
当关系词在从句中作宾语时可以省略,例如 This is the story he told me. 这是他跟我讲的故事.主句是this is the story, 从句是he told me ( the story).
加逗号只有一种情况：非限制性定语从句时加逗号,例如 The story, which is told by him, is a fake one. 他跟我讲的故事是假的.主句是The story is a fake one.从句是(the story) is told by him.
