2.原因状语从句
原因状语从句表示主句中动作或状态发生的原因或理由, 可位于主句之前,之后或插在主句中间。主句表示结果, 从句表示原因, 主要由because, as, since, for,
seeing ( that), considering ( that), now (that), in that, not ... because等引导。
1) because “因为’’as ‘‘,由于” , since “既然” , for “因为”
because 意为“因为” , 表示直接的原因或理由, 着重点在从句, 用于回答why,语气最强。
He is absent today because he is ill.
当主句为否定句时, 从句 because 须用逗号与主句隔开, 否则容易引起歧义。
I didn’ t visit him, because I wanted to borrow some books.
我没去拜访他, 因为我想借几本书。
I didn’ t visit him because I wanted to borrow some books.
我不是因为想借几本书才去拜访他的。
as意为“由于”, 表示十分明显的原因,所引导的从句常位于主句之前, 有时也可位于主句
之后 ,一般说明因果关系, 着重点在主句, 原因或理由只是附带说明, 不用于回答why的问题,常用于口语。
As it is snowing, we shall not go to the park.
As this book is written in simple English, it is suitable for beginners.
since 意为“既然 , 由于”时表示对方已知的、无须加以说明的既成事实的理由, 只是一个附带说明。since = as it is the fact that ... 全句中心在主句。如从句表示的原因不是确定的事实, 就不能用since,通常用because.
Since everybody is here, let’ s begin our discussion.
Since you seem to know them, why don’ t you introduce me to them?
for是一个并列连词, 由for连结的表原因的句子常看作并列句, 它只提供一些补充说明或对
前一个分句加以解释, 不可前置。与because不同的是:because 引导的从句位置可前可后, 而for引导的分句只能后置, 且往往须用逗号或分号与前一个分句分开。
I didn’ t go to see him, for a heavy snow was falling.
The days were short, for it was now December.
有时 , for 引起的从句并不表示原因, 而是表示一种推断或解释,而 because 则不能。
Someone in the house must be ill, for a doctor has just come out.
He couldn’ t have seen me, for I was not there.

2)用下列短语引导 :
seeing (that) “鉴于 , 既然” , considering (that) “考虑到” now (that) “既然” , in that “因为” , not ... because “不是因为” not that ??but that “不是因为而是因为 , ’
seeing that 与 considering that 同义 , 含义近似 since,所引导的句子中心在主句 , 重在强调结果。
Seeing that the weather is bad, we Considering that they are newcomers, they ’ ll stay at home.
’ ve accomplished a lot.
now that 的含义与 since(“既然”）接近 , 区别在于 :since 表示原先已存在的情况 , 而 now that 表示由于新情况的出现而促成某事发生。
Now that it has stopped raining, let Now that you are all here, let
’ s start at once. ’s try to reach a decision.
in that 作“因为”解时 , 由于介词 in 的含义是指“在方面” , 有限制作用 , 因此多指由于某一方面
的原因或理由 , 不能位于句首。
I like the city, but I like the country better in that I have more friends in the country.
I could understand his point of view, in that I’ d been in a similar position myself.
not ... because 意为“不是因为”, 该结构中的not 否定 because。
She didn’ t marry you becauseyou had money.
她不是因为你有钱才嫁给你。
The machine didn’ t stop because the fuel was used up.
机器不是因为燃料耗尽才停下来的。
not that ... but that作“不是因为而是因为”解。

He felt a bit worried, not that they were not working hard, but that they didn’ t pay enough attention to safety.

原因状语从句的用法 原因状语从句表原因，以下逐一介绍高考中常见的原因状语从句的引导词： 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，有时也否定主句例如： The country is not strong because it is large. 国强不在大。I 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) everyb ody 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。注意： 1. considering 和 given 还可用介词。如： Considering his age, the little boy reads very well. 就他的年龄来说，这小孩读得 挺好的。 Given her interest in children, I am sure teaching is the right career for her. 考虑到她喜欢孩子, 我可以肯定教书是最适合她的职业。 2. 表示“因为”的连词不能与表示“所以”的 so 连用。如： 译：因为他病了，所以没有出席会议。 误：Because he was ill, so he didn’t attend the meeting. 正：He didn’t attend the meeting because he was ill. 正：He was ill so he didn’t attend the meeting 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.

高中英语状语从句用法详细解析 一、定义： 在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。 二、分类 根据意义上的不同，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句 三、时间状语从句 （一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once. （二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。
2.原因状语从句 原因状语从句表示主句中动作或状态发生的原因或理由, 可位于主句之前,之后或插在主句中间。主句表示结果, 从句表示原因, 主要由because, as, since, for, seeing ( that), considering ( that), now (that), in that, not ... because 等引导。 1) because“因为’’, as‘‘由于”, since “既然”, for“因为” because意为“因为”, 表示直接的原因或理由, 着重点在从句, 用于回答why,语气最强。 He is absent today because he is ill. 当主句为否定句时, 从句because须用逗号与主句隔开, 否则容易引起歧义。 I didn’t visit him, because I wanted to borrow some books. 我没去拜访他, 因为我想借几本书。 I didn’t visit him because I wanted to borrow some books. 我不是因为想借几本书才去拜访他的。 as意为“由于”, 表示十分明显的原因, 所引导的从句常位于主句之前, 有时也可位于主句之后, 一般说明因果关系, 着重点在主句, 原因或理由只是附带说明, 不用于回答why的问题, 常用于口语。 As it is snowing, we shall not go to the park. As this book is written in simple English, it is suitable for beginners. since意为“既然, 由于”时表示对方已知的、无须加以说明的既成事实的理由, 只是一个附带说明。since = as it is the fact that ...全句中心在主句。如从句表示的原因不是确定的事实, 就不能用since,通常用because. Since everybody is here, let’s begin our discussion. Since you seem to know them, why don’t you introduce me to them? for是一个并列连词, 由for连结的表原因的句子常看作并列句, 它只提供一些补充说明或对前一个分句加以解释, 不可前置。与because 不同的是:because引导的从句位置可前可后, 而for引导的分句只能后置, 且往往须用逗号或分号与前一个分句分开。 I didn’t go to see him, for a heavy snow was falling. The days were short, for it was now December. 有时, for引起的从句并不表示原因, 而是表示一种推断或解释, 而because则不能。 Someone in the house must be ill, for a doctor has just come out. He couldn’t have seen me, for I was not there. 一、填入恰当的连词 1. I didn’t go to school yesterday _________ I was ill. 2. ________ everybody is here, let’s begin our meeting. 3. ________ you are in poor health, you should not stay up late. 4. I asked her to stay to tea, ________ I had something to tell her. 5. ________ all the passengers are here, why don’t we start at once? 6. Bill won’t make any progress ________ he doesn’t study harder than before.

I came back ______ ______ the ______ rain. 练习答案： 一、1.because 2.Since 3.As 4.because 5.Since 6.because 7.for
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3.

The moment he saw me, he ran away. 他一看见我，就跑了。 He said he’d call you the moment he got home. 他说他一到家就给你打电话 （3）The instant I saw him, I knew he was the man from the restaurant. （4）Immediately you begin to speak, he gives you his full attention.你只要一开始说话，他就全神贯注地听。 （5）My sister came directly she got my message. 我妹妹一收到我的信息就来了。 （6）Every time I listen to your advice, I get into trouble. （7）no sooner... than... ，"一...就..." ，引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. （8）He had hardly sat down when the telephone rang.他刚坐下电话就响了。 He had scarcely sat down when there was a knock at the door. 他刚坐下就有人敲门 另外，如果把hardly放于句首，主句要用倒装结构。如： Hardly had I finished eating when he came in. 我刚吃完他就进来了。 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句
二、原因状语从句：、定义：1在句中用来说明主句原因的句子叫原因状语从句。: 、常用引导词2now (that)becauseas since(既然(既然),) (因为), ), (由于、时态：3原因状语从句一般都是根据实际情况选用适当的时态。通常是主过从过，主现从现。4、because, since和as的区别： 1) because引导的原因状语从句一般放于主句的后面，because从句位于句首时要用逗号分开，放在句末时，可不用逗号分开。because表示直接原因，语气最强，最适合回答why引导的疑问句。because of 也表示原因，但它后面不接从句, 只能接名词, 代词或动名词。注意：because 和so 不可同时出现在一个句子里。①I do it because I like it. = I like it so I do it. ②We went by bus because it was cheaper. = It was cheaper so we went by bus. ③He can't go to school because of his illness. 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”= 弱。语气比because 较为正式，now that )，①Since you are free today, you had better help me with my mathematics. ②Since you don't trust him, you should not employ him. ③Now (that) you are grown up, you should not rely on your parents. 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”，含有对比说明的意味，语气 比since弱，较为正式，位置较为灵活(常放于主句之前)。 ①As it is raining, you'd better take a taxi. ②As you are tired, you had better rest. ③I went to bed early, as I was exhausted. 4) for引导的是并列句表示原因但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引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。 ①He could not have seen me, for I was not there. ②He seldom goes out now, for he is very old. 5. 三、目的状语从句： 1、定义：在句中用来作目的状语的句子叫目的状语从句。． : 2、常用引导词in order that so that )以便(以便),(、时态：3目的状语从句一般都是根据实际情况选用适当的时态。也通常是主过从过，主现从现。、目的状语
状语从句 在复合句中作状语，位置灵活。 状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。 （一）时间状语从句 1.when, as, while a.when表时间，从句既可以用延续性动词，又可以用瞬间动词。 Eg: When I get there I will call you. 如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be 可省。 Eg：When （you are）in trouble, you can ask her for help. 如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。Eg：When I came into the room(When coming into the room), I found the light was off. b.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。主句的谓语动词 通常是非延续性动词。 Eg: He came in while I was reading a book. I met her while I was in school. c. as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行。同时可表示主句的动作随着从句的动作的变化而变化。 Eg: He jumps as he sings. As the wind rose, the noise increased. 2.before(在……之前)与after（在……之后） Eg：See me before you leave. I saw them after I arrived. 3. till与until 肯定形式表示的意思是"做某事直至某时"。否定形式表达的意思是"直至某时才做某事"。 Eg: Wait till/untill I call you. 等着直到我叫你。 She didn't arrive till/until 6 o'clock.. 她直到6点才到 但是置于句首时只可用untill. Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。否定形式有另外两种表达方式： (1)Not until …在句首，主句用倒装。 Man did not know what heat was until the early years of the 19th century. =Not until the early years of the 19th century did man know what heat was. (2)It is not until…that… He will not go to bed until his mother comes home. =It is not until his mother comes home that he will go to bed. 4. as soon as/the moment/the instant/the second/the minute/immediately和hardly/scarcely…when, no sooner…than a. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和从句的动作同时发生。译为“一……就” Eg：As soon as she heard the news, she began crying. b. hardly/scarcely…when, no sooner…than都可以表示"一……就……"的意思，但主句谓语动词一般要用过去完成时，从句谓语动词要用一般过去时。 Eg：I had hardly / scarcely got home when it began to rain. I had no sooner got home than it began to rain.注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构：Hardly / Scarcely had I got home when it began to rain. No sooner had I got home than it began to rain。 1. We called the First - Aid Center_______ the traffic accident happened. A. immediately B. shortly C.quickly D. hurriedly 2.
