,of which的定从 改成 that 的

as做介词时,有 （ 作为.）的意思 例如He worked as a cashier in a bank
as做连词时,是 (像.)的意思 例如Do as he does
当意为 (如同,按照） 时 ,引导方式状语从句.例如you must do everything as i do
当意为（ 当.时候,一面.一面,随着 ）时,引导时间状语从句 例如they sang songs as they are doing farm work
当意为 (因为,既然） 时,引导原因状语从句 例如as they was not ready in time ,we went without him
当意为( 尽管 )时,引导让步状语从句 例如clever as he is ,he works very hard
在定语从句中,当先行词被the sane ,such 修饰时,定语从句需要用as引导,虽然that 也可引导,但前者表示同样或同类,后者表示同一个
当非限制性定语从句放在主句前时,要用as引导,例如as is known to everybody+一个句子

这个介词to+which是作动词go后面的状语啊,如果句子改成In Beijing there are some famous places of interest --- the tourists can get to enjoy the beautiful scenery.也就是go改成get,这里就可以用from which,你再想想

语法分析?这句应该看so/such.that.这个关键结构词.
这是个固定句法.非得解释我觉得你还是找大学里英语系的教授吧.
不过你要说定从.是这样的吧,he is a clever boy who everyone likes.
上面那种句子的学习方法可以尝试背例句,例句见的多了就慢慢明白了,固定用法.
他是个如此的聪明的男孩以至于每个人都喜欢他.

句子不完整,不能用关系副词where when which
In towns 【that 】are near the sea‘
后面are near the sea‘不是完整的句子（缺主语）,所以不能用where
举个例子：This is the city where I was born
I（主） was born（谓）.齐全,the city是状语,补充说明born在哪儿.
可还原为 I was born in the city

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

in which they live确定无疑是定语从句,修饰先行词environment.
修饰名词或者代词的是定语从句或者同位语从句.
状语从句都是来修饰谓语动词,表明动作的方式、时间、程度、地点等.

Before leaving the classroom,we have to turn off the fan which will save energe.

选D
因为前面问的是“哪里”,所以后面回答就应该是“地方”.
“where we worked”是形容“farm”,“我们工作过的那个农场”.
强调句的话应该这么说：It was the farm that we worked on.强调句的“It was”后面,这里应该是一个名词来回答“哪里”.
如果选“B”,这句话就变成“我们是在农场工作”,强调的是“我们在哪里工作”,而不是回答上一句的“从哪里知道”.
如果问：“Where did you work?”,就可以选A.

The annual festival celebrations are usually held in February 15, this day People dress up in costumes! Arrived at the people's Square, we immediately tell the children to play together (on D Oing)

1.定从中的关系副词可以引导非限制定语从句的,如
the factory,where my father once worked,is closed now.
2.定从中的关系副词做状语,是指这个关系副词在定语从句中代替先行词做状语.而状语从句中是没有先行词的.
如 the letter reminds me of the time when we lived together.
when he came in,he said nothing to us.
3.名词性从句相当于一个名词
定语从句相当于一个形容词
状语从句相当于一个副词
4.及物,不及物动词及这三种从句的关系,尤其是限制性和非限制性定从?你到底想问什么呢?
在定语从句中,及物动词后缺的是宾语,就要用关系代词 that,which,who 等.
不及物动词后面缺的是状语,要用关系副词 when,where,why.
5.当主句和从句有逗号隔来是,有无连接词的引导词选择问题.---我个人觉得你这个问题问的太模糊了,我不知道你要问什么,最好是具体一些.
我能回答的就这些,

It was exactly what I needed
That's when I decided.
两句都是表语从句.
表语从句
在句子中起表语作用的从句叫做表语从句.表语从句的引导词和主语从句的引导词相同.
What the police want to know is when you entered the room.
警察想知道的是你什么时候进的房间.
The trouble is that we are short of funds.
困难是我们缺乏资金.
This is what we should do.
这是我们应当做的.
That's why I want you to work there.
那就是我要你在那儿工作的原因.
His first question was whether Mr.Smith had arrived yet.
他的第一个问题是史密斯先生到了没有.

What can i do next? Nobody believed what i said just now

The delegates have met the situation where they should make decisions at once.
遇到situation / system做定语从句的先行词时,定语从句引导词要用where

此处讲解的东西,你先记下来,仔细读例句.
以第一个句子为例.
He appeared at the second window, from (从)where (这个地点~=the place) he could see nothing.
表示从什么地点看别处
这里的from 不多余,where 可以理解为the place,
如果,把from 去掉,意思就和上句不同了,请看：
1.He appeared at the second window, where he could see nothing.
他出现在第二个窗户,他看这里啥都没有. 没看到这里有啥.
这句里的where 可以用at which
2., from where he could see nothing. 从这里啥也看不到.从此处向别的地方看,比如着个窗户台上有花盆,但是看不到别处的东西. 而上面的句子,说的是这窗户附近啥都没有.

其他三个讲解,类似.

A不能选 如果你要选A做为独立主格应该用many of them children.这是结构不是句子,因此不能出现谓语(were).而用定语从句（C项）就是句子,可以出现谓语.明白吗?

that后面句子是定语丛句,修饰前面the way,又因为该定语丛句中不缺成分,故用that引导.要是缺成分,一般用which,where引导!which,where在句中做成分!比如做定语丛句主语.

I think I should influence the people around me are from ourselves to

在上一句中, understand后没有宾语, 因此as要充当成分,做understand的宾语, 所以as引导的就是定语从句. 而在下一句中, understand后有宾语it, 因此that不充当成分,那that引导的就不是定语从句,而是结果状语从句. ...

=Life always has many things that can bring you down!

1.It's difficult that learn English.
2.It's the place where i met you one year ago.
3.He went home having meal

定语从句；
先看主句：It was this house,这是一个完整的句子.it 是形式主语.
where I was born,修饰先行词house,这是定语从句,where作为连系副词,意为在（到）……的地方.

你说的是不是of which +the +名词?如果是的话就等于whose +名词
The house whose roof was broken is being repaired now.
=The house of which the roof was broken is being repaired now.
=The house the roof of which was broken is being repaired now.

一、the reason why肯定是定语从句
二、the reason that 不一定都是定语从句,分以下两种情况
1.当that后面加的句子是完整的句子的话,那它肯定是同位语从句,例如
He gave me the reason that he got up too late this morning.
2.当that 后面加的句子是不完整的句子的话（也就是缺少主语、宾语或表语时）,那它就是定语从句了,例如
I believe the reason that he gave.
He gave me the reason that was unbelievable.(他给了我一个令人难以置信的解释)
希望能帮助到你!

这个考的是加ing形式的引导的状语从句
很明显whom 是后面addressing 的宾语嘛.只要这样想,depend on sb!对不对?那把sb改为一句一个句子,那么就需要一个词来引导.要是宾语,而且是人物,一般就是用whom,要是地点的话,用where
比方：depending on where you are gonging to 根据你想去哪来决定
要是指待不确定的物体的话用 which,比方说 depending on which book you like 根据你喜欢哪本书里决定.

1.是强调句,it's ...that 句型,内在美最重要.
2.when：当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时,它只能作定语从句的时间状语,放在定语从句句首.如果定语从句的引导词是作该定语从句的主语或宾语,则要改用关系代词that或which来引导.例如：
The days when we used foreign oil are gone.我们用洋油的日子一去不复返了.
3.当定语从句中缺少主表宾定语时,用关系代词,缺少状语时用关系副词.
1.This is the reason ___ he gave me for his being late.
2.The reason ___ he was late this morning is still unknwn.
例句1中 ___ he gave me for his being late是定语从句,从句中谓语gave缺少直接宾语,并且此处的直接宾语应该是前面的先行词reason,所以用关系代词.
例句2中 ___ he was late this morning 是定语从句he was late this morning 且主系表完整,缺少状语,所以选用关系副词.

The boy who is 7years old is reading a book.

遇到从句,最好把它拆成简单句.这两个都是非限定性定语从句,只不过从句的引导词在从句中做状语,不是时间状语而是地点状语.

1. 从句还原后：There was a talent show（主语） going on （谓语）(at the place) then（时间状语）.
从句里面主谓和时间状语都全了,所以引导词只能做地点状语,指代the cinema.所以此题选where而不是when.如果句末的then不存在则可以选B.

2. 理由同上,从句还原后为：
Boats have been prohibited from saling around (in the place) since then.
因为有since then的时间状语,所以缺少的是地点状语where,指代a nature reserve.

定从中as不能作为关联词
she had a visit in Paris是从句 修饰a wonderful time
Mrs Black had such a wonderful time last year.是主句

其实强调句和定语从句的区别还是很明显的.
只是在一些情况下两者颇为相似,比如你举的这个例子,你看
1.It is a book that I bought yesterday 这句是强调句 ,意思是强调,我昨天买的是一本书而不是别的
2.it is the book that I bought yesterday 这就是定语从句了,因为一旦对书 做了修饰限定之后,书就必须是特指的,就要用定冠词the 而不能用a 翻译成,这就是我昨天买的那本书.
那么为什么说两者区别很明显呢,因为强调句可以强调句子里除了谓语之外的所有成分,而定语从句只能修饰限定宾语
你看 你可以说 It is yesterday that I bought the book （强调我是昨天买的这本书而不是别的什么时候）
或者也可以是 It is I that bought a book yesterday (强调是我买的而不是别人买的）
而定语从句就不能有这样多的形式.
而你最后说,如果不用从句,意思也能表达清楚,但是你看it is a book (that) I bought yesterday
和 I bought a book yesterday 虽然表意基本相同,但是应用的场景却不同,也就是语境不同,前者用于别人问你 你昨天到底买了什么呀?
后者只是简单的陈述

that 引导的名词性从句（主从,宾从,表从,同位语从句）,从句意思完整,句子完整.that只起到引导的作用,它不充当从句的句子任何成分,也没有什么的意思.在引导宾从时that 一般可以省略.引导其他名词性从句时不省略.
whether/ if引导的名词性从句,whether/ if含有“是否”之意,如果去掉whether/ if,从句的意思是不完整的,但是句子结构还是完整的.并且它不可省略.
定语从句的引导词,是有实际意义的并且在从句中充当相应的成分（主语,宾语,表语,定于,状语）,
状语从句必须要连词来引导,并不能省略,从句结构完整,但是如果少了连词的意思,整个从句意思就不完整.

既非宾语从句,也不是定语从句.这是个表语从句.
主语：That
谓语：is
表语：where I come from in the first place .有where引导的表语从句.

这是固定搭配,没有老师说的那么复杂
the way后面跟定从的话,有三种接法
the way that,the way in which ,第三种就是the way 后直接加定从..
这三种接法可以互换..意思一样

英语中从句有三种：状语从句（副词性从句）；定语从句（形容词性从句）；名词性从句（包括主语从句,宾语从句,表语从句和同位语从句）.什么名称的从句即在整个句子中充当什么样的成分.例如：
状语从句：
1.i didn't catch the train because i get up late this morning.(because引导的原因状语从句)
2.if it should rain tomorrow ,we would put off the meeting.(if引导的条件状语从句)
3.As I was wandering in the street,I met her.（as引导的时间状语从句）
4.Where there is a will,there is a way.（where引导的地点状语从句）
5.Although (though) I gave him some advice,he didn’t take them.（although引导的让步状语从句）
6.You should do your homework as i did.（as引导的方式状语从句）
7.Cherry was walking quickly so that (in order that) she could arrived at the cinema in time.（so that 引导的目的状语从句）
8.She is such a nice teacher that all of us love her.（such..that引导的结果状语从句）.
定语从句
是相当于形容词的作用限定修饰名词或代词的.所以定语从句一般是放在名词或代词后面的.（定语从句分限制性定语从句和非限制性定语从句,今天实在没时间打那么多了,改天再细细告诉你两者区分吧）.
1.The man who helped you is Mr White.(who代人,在定语从句中作主语)
2.I´m not the fool(that) you thought me to be.(that代人,在定从中作表语)
3.The house where they live is not very large（where指in the house）
4.This is the reason why he did not came to the meeting.（why引导的从句限定reason）
但不是表时间的先行词都用when引导定从,不是表地点的先行词都用where引导定从.
例如：5.We´ll visit the factory which(＝that) makes radios.
(which或that在定从中作主语,where不可用主语,故不可用)
6.They still remember the happy days(which/that) they spent in Beidaihe.
(which或that在定从中作spent的宾语,when不可作宾语,故不可用)
名词性从句
主语从句用作主语,如：：
That the earth is round is true.地球为圆的是真实的.
宾语从句用作宾语.如：
Do you know where he lives?
表语从句用作表语,如：
My opinion is that you should not go alone.我的意见是你不应单独前往.
同位语从句用于解释说明前面的名词.如：
The fact that the earth is round is true.地球是圆的的事实是真实的.（that从句用于解释说明the fact）
如果还有什么疑问尽管提.我会尽力的来解释清楚

英语简单句有五种类型,在构成句子时,由句子充当其中的成分的句子就是复合句.区分是什么从句关键看其是在复合句的整体结构中充当什么成分,是什么成分就是什么从句,做宾语的就是宾语从句,做定语的就是定语从句.
