求原因状语从句引导词.

As he is ill today,he does not go to school.

它只是突出这种惊讶的语气,意思是竟然

我认为没有什么大的区别,就是一个是表语从句,一个是状语从句
比如：That is because I love her.
（为什么我...,因为我爱她）
I'm late,because I got up late.
如果非要有区别,有这样一点：
状语从句可以用动词分词形式直接表示,表语从句当然就不行了,Eg:
He doesn't want to go there because he knows there's a war right now.
改成：Knowing there's a war right now,he doesn't want to go there.

since译为“既然”,表已经知道条件的情况下.一般用在主句之前.
as译为“因为”,强调主从句并重.

1.Soon,he told me the whole thing.
2.As he did not know the meaning of this word,so consult a dictionary
3.If I did not receive his letter,did not give him the letter,
4.While we do not singly,the body is not strong,but a good team
5.He was so excited so speechless
6.Last week,he suddenly fell ill so that we are all surprised
7.He is not too large for the relationship between
8.He said nothing,which makes everyone was surprised
9.To stop all violence on television bar.Since it is the people that wounding or even killing,this is a misconception.
10.When I walked into her grandmother lying in a room,my heart began to sink.This will be the last time I saw he

the gift is a car, which i refused to accept, because it is too expensive and i don't need a car to go to school.
the 2008 olympic games is a great success, which shook the world by its brilliance, because it combined the achievement of the past and the dream of the future of china to the world.

根据语境,这里的In that 其实相当于“in that case" "【这样一来】,摄像头便捕捉不到任何的空位”

1.可以引导原因状语从句：for表现的因果关系不像because那样强烈,它引导的原因状语从句并不说明主句行为发生的直接原因, 只提供一些辅助性的补充说明,例如： He could not have seen me, for I was not there. 他不可能见过我, 因为我不在那里.
2.也可以引导定语从句
3.理论上是可以回答Why的,但是一般和Why对应的是because

I was late for class,because i overslept this morning.
Since you have no class tomorrow,you can stay up late tonight.
She is your sister,for this,you should respect her.
The dog runs to him as he opens the door.

She fought with a boy, because he said something bad about her fathe

引导原因状语从句的连词：because（因为）；as（由于）；since,now　that（既然）；seeing　that（鉴于）等.
（１）because,since,as都可表示“因为”.
①because表示原因的语气最强,通常回答以疑问词why引导的问句,除特别强调外,该从句一般位于主句后；since表示稍加分析后而推断出来的原因,比as正式；as表示对方已知道的原因.since和as不回答why引导的疑问句,而且其从句一般放在句首：
IdoitbecauseIlikeit.
因为我喜欢我才干.
Sincenooneisagainstit,let’scarryouttheplan.
既然没人反对,我们就执行这个计划吧.
Ashewas’treadyintime,wewentwithouthim.
由于他未及时准备好,我们没等他就走了.
②because是连词,because　of是介词短语.
③because和so不可同时使用,只用其中的一个.
④for也常引导表示原因的分句,但for是并列连词,因此不能用于句首；for所提供的理由是一种补充性的说明,且for前常有逗号：
Thedaysareshort,foritisnowDecember.
白天短了,因为已是１２月了.
（２）部分表示感情的状态形容词（如sorry,glad,pleased等）有时可接一个that引导的从句表示原因,作状语从句（但也有人认为是宾语从句）：
IamsorrythatIhavecausedsomuchtrouble.
真对不起,给你添了这么多麻烦.

since在时间状语从句中,延续性动词与非延续性动词都可接.接短暂性动词时表示从这个动作发生之时算起一直到现在的这一段时间.接延续性动词时表示从这个动作结束之时算起起到现在的这一段时间.如：
He has been in the school since 1998.他1998年以来一直在这所学校工作.
He has been in the company since he studied in Nanchang University.他南昌大学毕业后一直在这家公司工作.
since在原因状语从句中也是延续性动词与非延续性动词都可接.但那没有多大的探讨意义.

按高考53来讲　并列句中的表因果关系的常用连词只有so ,for.eg.It must have rained last night for it is wet all over.for连接的两个简单句互相独立,“遍地是水”仅为推测并不一定是真正原因,并列句中的因果一般都表推测.而because则是在原因状语从句中做从属连词表示直接因果关系.

顾名思义,原因状语从句在主句中充当原因状语,可以译为：因为,多由because,as,since,now that,in that,seeing that 等充当引导词.而目的状语从句则充当目的状语,译为：为了,多由in order that,so that,in case,for fear that等充当引导词.

其实一般情况也可以用现在时.不过请您注意16中时态的那个表格.挺管用的.

ecause.和as

ecause 放于主句前或后
as/since/now that放于主句之前
for放于主句之后
如果还不太清楚,请到我的空间留言提问

简单点回答就是表示原因强弱不同,
beacuse最强,就是解释原因,通常用于回答why这种问原因的词.
而since,表示显而易见的原因啦.给你举个例子,为什么天是蓝的?用什么回答?当然是beacuse,.
而我说 因为天是蓝的,所以.这个因为用since,表示显而易见的原因,既然天是蓝的,所以.位置也能看出来,since 用于句首,beacuse通常用在逗号前吧.

Confused by the stones flying at them from all sides,the boys ran into the building.

是目的状语从句.

不太理解lz的意思== 可以给个例题么

1）引导原因状语从句的连词主要有because, as, since:　　because:　　Because it was wet he took a taxi. 由于下雨他叫了一辆出租车.　　He was worried because he hadn’t had any letter from her.　　他很担忧因为他没收到过她一封信.　　as:　　As David had a passion for walking, we started off on foot. 　　由于大卫喜欢走路,我们就步行出发了.　　As you’re sorry, I’ll forgive you. 既然你悔悟了,我就原谅你. 2）还有一些表示原因的状语从句由seeing（that）,considering(that)或now that等引导：　　Please don’t try to back out now that everything has been arranged.　　现在一切都安排好了,请不要打退堂鼓.　　Now you’re here, you may make yourself useful. 你已经来了,不妨帮帮忙.　　3）许多用在形容词后的that从句也起原因状语的作用（that 有时可省略）：　　She was glad that she had controlled herself. 她很高兴控制住了自己.　　I’m disappointed that they cannot come. 他们不能来我很失望.

1.That's because you did not lock the door!
That's because I believe in you!
That's because it costs too much to buy.
That's because You walked out of me!
That's because you did not listen to me.
2.I'm sure that this can be solved in no time at all.
I'm sure that you know what i am talking about.
I'm sure that there are plenty other people just as poor as me.
I'm sure that you can do it very well.
I*'m sure that this won't be a problem at all.

with的复合结构嘛
作的成份很多
可以表示不同的意思
原因 结果 条件等

1.可以引导原因状语从句：for表现的因果关系不像because那样强烈,它引导的原因状语从句并不说明主句行为发生的直接原因,只提供一些辅助性的补充说明,例如：He could not have seen me,for I was not there.他不可能见过我,因为我不在那里.
2.也可以引导定语从句
3.理论上是可以回答Why的,但是一般和Why对应的是because

it做形式主语,可以代替that从句,不定式等,避免句子头重脚轻.
第一句,如果用it,后面要加个that.
如:It is generally accepted that the ...
第二句It being cold,表示伴随性状况,it指天气
as不能用没,因为as引导从句,being cold是非谓语动词,这里没有谓语动词,构不成从句.
(不知道为啥,系统不让我通过,貌似没有什么词敏感吧,尝试再发一遍)

两个都表示既然,用来表明众人皆知的原因,可以互换使用,注意这个that不可省略

〔考题1〕 ____ you’ve got a chance,you might as well make full use of it.(1999)
A.Now that B.After C.Although D.As soon as
〔答案〕 A
〔解析〕 主句与从句之间存在因果关系,且“you’ve got a chance”表示一个显而易见的原因,因此应选用表原因的now that.
〔考题2〕 He found it increasingly difficult to read,____ his eyesight was beginning to fail.(2006北京)
A.and B.for C.but D.or
〔答案〕 B
〔解析〕 “his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因,因此本题应选用可以表示原因的连词for引导原因状语从句.
〔考题3〕 A man cannot smile like a child,____ a child smiles with his eyes,while a man smiles with his lips alone.(2006湖南)
A.so B.but C.and D.for
〔答案〕 D
〔解析〕 下划线处之后的句子补充说明“a man cannot smile like a child”的原因,应选用for表原因.

你这么改不错,但是有点违背句子的原意.
因为这里没有出现人称.所以你的人称不能乱加.
这里最好的改法是
Because this ariticle was written in a hurry,it was not so good
written是过去分词,它的逻辑主语是 this article.所以这么改最准确.
如果您觉得答案对您有帮助,请及时采纳,如果仍然有问题,请继续追问~

1. because引导的原因状语从句一 般放于主句之后， because表示直接 原因， 语气最强， 最适合回答 why引 导的疑问句。例如： I do it because I like it. 我做这件事是因为我喜欢。 注意： “not ... because”结构中的 not否定的是because引导的整个从 句， 例如： The country is not strong because it is large. 国强不在 大。 2. since引导的原因状语从句 一般放于主句之前表示已知的、 显然 的理由(通常被翻译成“既然”)， 较为正 式， 语气比because弱。例如： Since you are free today, you had better help me with my mathematics. 既然 今天你休息， 你最好帮我补习数学。 注意： seeing (that)， now (that)， considering (that)， in that 这几个词汇与since引导的原因状语从 句意思相近， 都表示“既然”。例如： Seeing (that) he refused to help us, there’s no reason that we should now help him. 他既然曾经拒绝帮助我 们， 我们现在没有理由要来帮助他。// Now (that) you are grown up, you should not rely on your parents. 既 然你长大了， 就不应该依靠你的父母 了。// Considering (that) everybody is here, let’s begin our discussion. 既 然大家都到了， 我们就开始讨论吧。// In that he is ill, he feels unable to do it. 因为有病， 他觉得做不了那件 事。 3. as 引导原因状语从句时表 示附带说明的“双方已知的原因”， 语 气比since弱， 较为正式， 位置较为 灵活(常放于主句之前)。例如： As it is raining, you’d better take a taxi. 既 然在下雨， 你最好乘出租汽车。// As you are tired, you had better rest. 既 然累了， 你最好休息一下。// I went to bed early, as I was exhausted. 我 睡得早， 因为我筋疲力尽了。 4. for引导的原因状语从句并不说明主句 行为发生的直接原因， 只提供一些辅 助性的补充说明， for引导的原因状语 从句只能放于主句之后并且必须用逗 号将其与主句隔开。例如： He could not have seen me, for I was not there. 他不可能见过我， 因为我不在 那里。

1.since较as意味略强.它们都可以表示较明显的或对方已知的原因.可分别译作“既然”和“由于”.since和as从句一般放在主句之前.例如：
Since his method doesn't work,let's try yours.既然他的方法不行,我们就试试你的吧.
As I didn't know how to do it,I asked the teacher.由于我不知道怎样做,就问了老师.
2.for是并列连词,位于两句之中,连接并列的分句.当for表示因果关系时,可与because换用,但在for前面须用逗号.例如：
You couldn't have seen him,because/for he wasn't there.你不可能见到他,因为当时他不在那里.
for除此之外了表示因果关系外,还可以述说对主句中的事实或看法的解释.例如：
It will rain,for it's getting dark,要下雨了,因为天气越来越暗了.

ecause :I was late yesterday because I got up late.我昨天迟到的原因是我迟起了.
as ：I went to bed early,as I was exhausted.我睡得早,因为我精疲力尽了.
since :Since you're not interested,I won't tell you about it.既然你不感兴趣,那我就不告诉你了.
for :The picnic has been canceled for the weather was really bad.野餐取消了,因为天气不好.

coordinate,not subordinate clause.
(并,not 从; and it is usually seen as American English by some.)

这是个定语从句,肯定不是状语从句,.的原因.如果是同位语从句的话,why引导的从句就是reason,而不是I am late

不能
原因状语从句的引导词是because,as,since,now that（既然）

1.for one of the reason that
2.appreciation of

这个要分两个部分,应为原因状语从句严格的说是有2个句子,一个是主句,一个原因状语,也是句子,用个例子,I want to go home because of that---- 在主句,就是以I开头的那部分里,可以用一般现在时代替将来时,应为主句中所说的动作可以发生在任何时间.在从句里,就是because of that后面跟的那个句子,大部分要用过去的时态,不可以用一般现在时代替将来时,应为是原应,应该发生在主句的时间之前.

用脑子用

楼主,四者均可用来表示原因,区别如下：(1) 关于because：语气最强,表示直接原因,可用于回答 why 提出的问题、引导表语从句、用于强调句等,而其余三者均不行：“Why didn’t he come?”“Because he was ill.” “他为什么没来?”“因为他病了.” My stomach hurts because I have eaten too many apples.我肚子痛,因为苹果吃得太多.That’s because you can’t appreciate music.这是因为你不能欣赏音乐.It is because he is honest that I like him.是因为他诚实我才喜欢他.(2) 关于since 与 as：a.两者所表示的原因都是人们已知的,即对已知事实提供理由,而不是表示直接原因.since 比 as 语气稍强,且比 as 略为正式,它们引导的从句通常放在主句之前,有时也放在主句之后：As you weren’t there,I left a message.由于你不在那儿,我留了个口信.Since you are wrong,you should apologize.你既然错了,就应该道歉.b.since 可用于省略句,而其他三者不行：Since so,I have nothing to say.既然如此,我无话可说.(3) 关于for：是并列连词(其余三者为从属连词),它有时可表示因果关系(通常要放在主句之后,且可与 because 换用)；有时不表示因果关系,而是对前面分句内容的解释或推断(也要放在主句之后,但不能与because 换用).比较：The ground is wet,for (=because) it rained last night.地面是湿的,因为昨晚下过雨.It must have rained last night,for the ground is wet this morning.昨晚一定下过雨,你看今天早上地面是湿的.(此句不能用 because 代 for)

条件状语

时间状语从句关系词when,while ,as ,after,before ,long before,before long,until ,till ,not until...
地点状语从句关系词没听说过
原因状语从句关系词because,as ,for,cause
目的so..that
让步though,although

不能置于句首啊 在一个for引导的不是叫原因状语从句 ,而是并列句

这句子里有两个从句,一个是who引导的定语从句,另一个是wherever引导的是让步状语从句.句中不定式to weak up做主句的状语,但不是从句

（1）?you went to England ,tell us what you did and saw there.
A:because B:for C:as D:since
（2） the weather is fine,we will go on a trip.
A:because B:for C:as D:since
1.D since在这里表示既然的意思.既然你去过英国,跟我们说说你在那所做所见的事吧
2.C表示因为,从属连词,说明一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句通常放在句首,有时也可放在句末.
顺便说说这几个词的区别：
because 是从属连词,接表示直接原因的从句,一般放在主句的后面,也可放在主句前面,它表示的语气最强,在回答why的问句时,必须用because.
since 意为"既然",表示对方已知的无需加以说明的原因或事实,语气比because弱,但是比as 强.
for 是并列连词,用来附带解释说明前一分句的原因或理由,for引导的并列句,一般放在所要说明的句子的后面.
as 是从属连词,说明一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句通常放在句首,有时也可放在句末.
...自己弄个错题本不都有了

给你举两个例子体会一下:
The reason why he didn't open the door was that the door was locked.
The reason that he replied to the customer by email is unacceptable.
有时候不要过于死扣语法,多阅读,多体会语境,在考试做题的时候帮助很大.

As it's fine today, I've opened all the windows

英语表达中,有BECAUSE 就不能有SO; 有SO,就不能有BECAUSE.
有ALTHOUGH/THOUGH,就不能有BUT; 有BUT,就不能有ALTHOUGH/THOUGH.

〔考题1〕 ____ you’ve got a chance,you might as well make full use of it.(1999)
A.Now that B.After C.Although D.As soon as
〔答案〕 A
〔解析〕 主句与从句之间存在因果关系,且“you’ve got a chance”表示一个显而易见的原因,因此应选用表原因的now that.
〔考题2〕 He found it increasingly difficult to read,____ his eyesight was beginning to fail.(2006北京)
A.and B.for C.but D.or
〔答案〕 B
〔解析〕 “his eyesight was beginning to fail”是“he found it increasingly difficult to read”的原因,因此本题应选用可以表示原因的连词for引导原因状语从句.

A.so B.but C.and D.for
〔答案〕 D
〔解析〕 下划线处之后的句子补充说明“a man cannot smile like a child”的原因,应选用for表原因
