一、原因状语从句
(1)原因状语从句通常由because, since, as, for引导。
(2)because表示直接原因，语气最强。because引导的原因状语从句多放在主句之后。回答由why提
出的问题，只能用because。此外，because和so不能同用在一个句子里。
例如：------Why aren’t going there?------Because I don’t want to.
since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴于……”。
例如：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散散步吧。
as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。
例如：As he has no car, he can’t get there easily.
Since we have no money, we can’t buy it.
(4)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。如:
I decided to stop and have lunch, for I was feeling quite hungry.
练习：I was late for class yesterday _______ there was something wrong with my bike.
He took off his coat _______ he felt hot.
you can’t answer the question, I’ll ask someone else.
二、结果状语从句
(1)结果状语从句由so…that, such…that, so that引导。
(2)so…that语such...that可以互换。在由so...that引导的结果状语从句中，so是副词，与形容词连用。
其结构是: “...so + 形容词（副词）+ that + 从句”。
例如：He was so glad that he couldn’t say a word.
Mother lives so far away that we hardly ever（几乎不，从来不）see her.
在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；其结构是: “...such +a / an + 形容词+名词+ that + 从句”。
例如：It was such a hot day that nobody wanted to do anything.
He had such long arms that he could almost touch the ceiling.（天花板）有时上述两种结构是可以互换的。
例如：It was such a wonderful film that all of us wanted to see it again.
=The film was so wonderful that all of us wanted to see it again.
(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。
例如：Soon there were so many deer that they ate up all the wild roses.
He has so little time that he can’t go to the cinema with you.
(4)如果主从句的主语相同，并且从句是否定的形式，可以用too...to...句型转化。
例如：He was so excited that he couldn't go to sleep that night. = He was too excited to go to sleep. (5)如果主从句的主语相同，但从句是肯定的形式，可以用adj.+ enough替换。
例如：He is so old that he could go to school. = He is old enough to go to school.
他够大了，可以去上学。
练习：It is ___ hot in the room ___ we have to go out for a walk.
It was a wonderful movie all of us wanted to see it again.
There were little water in the bottle the bird couldn’t reach it.
.

三、目的状语从句
(1)目的状语从句通常由so that, in order that（为了，以便）引导。
例如：We started early so that we could catch the first train.
We used the computer in order that we might save time.
(2)so that可引导目的状语从句，此时可用to或in order to替换,将其改为简单句。
例如：He got up early so that he could get to school on time.
=He got up early（in order）to get to school on time.
(3)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状
语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。
例如：Speak clearly so that they may understand you. (目的状语从句)
Jack is badly ill so that he has to rest. (结果状语从句)
练习：I hurried I wouldn't be late for class.
We should go by bus ___ we can get there earlier.
May I sit nearer I can see more clearly?
(4) 补充：
so as to…(肯定结构)
eg. He got up early so as to catch the early train.
so as not to…(否定结构)
eg.He got up early so as not to miss the early train.
to…
eg. He got up early to catch the early train.
in order that …
eg. He got up early in order that he could catch the early train.
in order to…
eg. He got up early in order to catch the early train.

10 逻辑关系（Logical relations） (61) 原因和结果 表原因的词：because, since, as, for, because of 表结果的词：so 一、原因状语从句 (1)原因状语从句通常由because, since, as, for引导。 (2)because表示直接原因，语气最强。回答由why提出的问题，只能用because。此外，because 和so不能同用在一个句子里。 eg：------Why were you late for school?------Because I got up late. since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴于……”。 eg：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散散步吧。 as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。 例如：As he has no car, he can’t get there easily. Sin ce we have no money, we can’t buy it. (3)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。如: I decided to stop and have lunch, for I was feeling quite hungry. 练习： I was late for class yesterday _______ there was something wrong with my bike. He took off his coat _______ he felt hot. you can’t answer the question, I’ll ask someone else. ________the bad weather, we missed the train. 二、结果状语从句 (1)结果状语从句由so…that, such…that, so that引导。 (2)在由so...that引导的结果状语从句 其结构是: “...so + 形容词（副词）+ that + 从句”。 Eg. He was so glad that he couldn’t say a word. Liping runs so fast that we can’t catch up with him. 在由such…that引导的结果状语从句 其结构是: “...such +a / an + 形容词+名词+ that + 从句”。 eg：It was such a hot day that nobody wanted to do anything. He had such long arms that he could almost touch the ceiling.（天花板）有时so…that和such...that可以互换。 Eg ： It was such a wonderful film that all of us wanted to see it again. =It was so wonderful a film that all of us wanted to see it again. (3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。 eg：Soon there were so many deer that they ate up all the wild roses. He has so little time that he can’t go to the cinema with you. (4)如果主从句的主语相同，并且从句是否定的形式，可以用too...to...句型转化。 eg：He was so excited that he couldn't go to sleep that night. = He was too excited to go to sleep. (5)如果主从句的主语相同，但从句是肯定的形式，可以用adj.+ enough替换。 eg：He is so old that he could go to school. = He is old enough to go to school.
结果状语从句 结果状语从句常由so… that 或such…that引导，掌握这两个句型，首先要了解so 和 such与其后的词的搭配规律。 比较： so和 such 其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little 连用，形成固定搭配。 so foolish such a fool so nice a flower such a nice flower so many / few flowers such nice flowers so much / little money. such rapid progress so many people such a lot of people （ so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能用such搭配。） so…that与such…that之间的转换既为 so与such之间的转换。 The boy is so young that he can't go to school. He is such a young boy that he can't go to school [编辑本段]考题解析 ［考题1］ Pop music is such an important part of society ____ it has even influence our language.

$ 状语从句练习题经典 一、初中英语状语从句 1．We’ll go to the farm and help the farmers with the apple-picking if it ______tomorrow. A．isn’t rain B．will be rainy C．doesn’t rain D．is raining 【答案】C 【解析】 【详解】 # 句意：如果明天不下雨我们将会去农场帮农民摘苹果。考查条件状语从句。根据题干We’ll go to the farm and help t he farmers with the apple-picking if it ______tomorrow.可知，if引导的条件状语从句，主句用将来时，从句需用一般现在时，句意是“明天不下雨”，rain是实意动词，主语是it，变否定用助动词doesn’t。故选C。 【点睛】 主将从现是指在时间状语从句和条件状语从句中，如果主句是一般将来时，从句用一般现在时替代一般将来时。 常见的有以下四种情况： 一、条件状语从句的主句是一般将来时，那么从句常常用一般现在时 如： When I grow up, I’ll be a nurse and look after patients 我长大后要当一名护士，照顾病人 二、如果主句是祈使句，那么从句通常要用一般现在时 ） 如：Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。 三、如果主句是含有情态动词的一般现在时，根据需要从句多用一般现在时 如：You should be quiet when you are in the reading room 在阅览室时应保持安静 四. 如果if的条件状语从句遇到变换间接和直接时 , 祈使句应用not to.... 如; She said not to close the window 常见的时间状语从句的连词有：as soon as,when,while ,as,until等 ~ 2．Tony has had to cook by himself ________ his mother went on business to Guangzhou. A．since B．after C．during D．when 【答案】A 【解析】 【详解】 句意：自从妈妈去广州出差以来，托尼不得不自己做饭。A. since从……以来；B. after
顾名思义，用来说明主句中谓语动词发生的目的的从句叫做目的状语从句。表示目的状语的从句可以由that（以便），so that（以便），in order that（为了；以便），Lest（免得；唯恐），for fear that（生怕；以免）等词引导；目的状语从句的谓语常含有may, might, can, could, should, would等情态动词。 例如：You must speak louder so that /in order that you can be heard by all. He wrote the name down for fear that(lest) he should forget it. Better take more clothes in case the weather is cold. 学习目的状语从句应注意以下两点： （1）目的状语从句中常含有can,could,may,might,should等情态动词。例如： I got up early so that I could catch the first bus. 我起得很早，目的是为了赶上头班公共汽车。 （2）在口语中so可以引导目的状语从句。例如： We'll sit nearer the front so we can hear better. 我们坐的靠前一点，因此，我们听得清楚一点。 1、in order that与in order to的区别： in order that+从句in order to+动词原形（in order to后面加的那个不叫目的状语从句，叫目的状语）例如： He got up early in order to take the first bus. = He got up early in order that he could take the first bus.（他起床很早是为了赶上第一班公共汽车） 目的状语从句的一个特点：由于目的都是未来的行为，所以从句中一般用表示未来可能性时态，比如上面句中的could。当然还可以用will,would,can,等。 2、so that既可引导目的状语从句，也可以引导结果状语从句。 1）其引导结果状语从句时，so that翻译为“以至于...”，经常可以和so/such...that...转换，且从句只能放在主句之后。如：He got up late so that he was late for school. = He got up so late that he was late for school. 2）其引导目的状语从句时，从句只能放在主句之后，此时可以和in order that换用。如：He got up early so that he could take the first bus. = He got up early in order that he could take the first bus. 常见考法 对于目的状语从句的考查，多以单选和完形填空的形式，从连词的意义角度让大家选择连词。 典型例题：Ann listened carefully _____ she could discover what she needed. A. such that B. in order that C. because D. even though 解析：题干的意思是“为了能够发现自己需要的东西，安认真听讲”。很明显从句表示的是目的。such that本身是错误短语，because 表示原因，even though是“尽管”的意思，不符合题意。 答案：B 误区提醒 如何区别目的状语从句中的so that与结果状语从句中的so that的用法，这是我们需要注意的。目的状语从句的so that是连着的，结果状语从句是分开的，即so…that. so that是目的状语从句，是为了什么什么，有目的的含义。而so…that是结果状语从句，是“如此怎么怎么样结果是什么”。仔细体会一下吧！ 典型例题：I get up so early I can not be late A. that B . so that C.such that D.in order 解析：题干的意思是“我起床如此早以便于我可以不迟到”。从句表示目的，首先排除C，因
教学过程 一、课堂导入 状语(adverbial)是句子的重要修饰成分。状语是谓语里的另一个附加成分，它附加在谓语中心语的前面，从情况、时间、处所、方式、条件、对象、肯定、否定、范围和程度等方面对谓语中心进行修饰或限制。在不同的语言中“状语”有不同的作用。 上节课已经学习了条件状语从句，对状语从句有两个一个基本的认识，今天我们就接着学习目的状语从句。
二、复习预习 对上一节课的时间状语从句布置的作业进行讲解，点评，让学生们通过讲评能够复习上节课的知识。之后给出几个目的状语从句的题目，让学生们自己思考讨论如何选择，并做出分析，这样可以形成学生们独立思考独立学习的习惯，老师听了学生们的回答之后可以知道同学们对目的状语从句盲点在哪里，后面的讲课中可以针对性地进行讲解。
三、知识讲解 知识点1：引导目的状语从句的从属连词 1【考查点】主要的有in order that, so that, in case, for fear等： Speak clearly so that they may understand you. 讲清楚些，以便他们能理解你。 He studied hard in order that he could pass the exam. 他努力学习以便能考试及格。Shut the window for fear that it may rain. 把窗子关上以防下雨。 【注】so that 引导目的状语从句时有时可省略so而只用that，有时也可只用so：Bring it closer that I might see it better. 拿近些，使我能看得清楚些。 I’ll show you so you can see how it’s done. 我将做给你看，以便你知道应怎样干。

目的和结果状语从句
一、目的状语从句 用从句来表示主句行为或事件发生的目的，这个从句就是目的状语从句。 常用引导词：so that, in order that 两者可互换 Mulan dressed like a man so that she could join the army. 为了能够参军，木兰穿戴成男 人的样子。 I got up very early in order that I could get to school on time. 为了能按时到校，我 很早就起床了。 从以上例句可看出，目的状语从句有一个特点：从句中一般都含有表示可能性的词语，比如 could。 其他还有 will, would, can 等。 二、结果状语从句 用从句来表示主句行为或事件发生的结果，这个从句就是结果状语从句。 常用引导词：so that, so ... that, such ... that 1、so that 意为“结果是……” ，从句中一般不出现表示可能性的情态动词；通常用逗号与主句隔开； He got up late, so that he didn’t catch the early bus. 他起晚了，结果没赶上早班车。 2、so + adj./adv. + that 从句，意为“如此……以致于……” ； Ｉwas so careless that I forgot something important. 我真是粗心，以致忘了重要的事情。 He speaks so fast that I cannot understand him. 他说话太快了，以致我不能理解他的意思。 3、such ... that ... 意为“如此……以致于……” ，常见结构如下： （1）such + adj.+ n. 复数形式+that 从句； （2）such +adj. +不可数 n. + that 从句； （3）such +a/an +adj.+ n. 单数形式+ that 从句 = so + adj. + a/an + 单数名词 + that 从句 He had such long arms that he could almost touch the ceiling. 他胳膊那么长，几乎能摸 到天花板。 He made such rapid progress that he did very well in the mid-term. 他进步如此之快， 期中考试考得非常好。 It was such a hot day that nobody wanted to do anything. 今天天气这么热，人们什么都 不想做。 = It was so hot a day that nobody wanted to do anything. 4、so ... that ... 和 such ... that ... 句型互换 It was such a wonderful film that all of us wanted to see it again.

目的状语从句的用法说明 by曹霞 目的状语从句主要的有in order that,so that,in case,for fear等。如： 1.由in order that引导 We used the computer in order that we might save time. I lent him￡50in order that he might go for a holiday. In order that you may create such a picture,you have to possess certain a rtistic weapons. 2.由so that引导 Come closer so that I can see you. I hired a boat so that I could go fishing. Speak clearly so that they may understand you. Put a mark on it so that you will remember it. Write to him at once so that he may know in time. 3.由in case引导 Be quiet in case you should wake the baby. Take warm clothes in case the weather is cold. I shall sit up for a time,in case I am wanted.。 Take your raincoat in case it rains(should rain). I wrote down her address in case I should forget it. I’ve bought a chicken in case your mother should stay for lunch.
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.
原因、目的、结果状语从句讲练 一、原因状语从句通常由because, since, as, for等词来引导。 连词because, as, since, for的用法区别： because表示原因时，用法最为广泛，语气也最强。它所引导的从句可以放在主句之前或在主句之后。 例： 1) -- Why are you always late for school? – Because my home is far from here. 你为什么总是迟到？因为我家太远。 2) He can’t come to the party because he is busy. 因为他忙，所以不能来参加这个聚会。 as在表示原因时，语气较强。它所引导的从句常放在主句之前，意思是“由于”；把众人所知的事实当作理由。 例： 1) As the bad weather, he was lost his way yesterday morning. 由于恶劣的天气，他昨天早晨迷路了。 2) As Mr. Liu is the new comer, he doesn’t have too many friends here. 刘先生由于初来乍到，因此在这儿没有太多的朋友。 since语气较弱。它所引导的从句一般放在主句之前，意为“既然”；就对方陈述的事实作为理由。 例： 1) Since Li Ming doesn’t know the answers to the problems, let’s ask Wang Lei to do it. 既然李明不知道这道题的答案，那就让王磊来回答吧。 2) Since we are good friends, please call me if you need help. 既然我们是好朋友，如需要帮助，请尽管打电话。 相比较而言，for的语气最弱。其引导的从句放在主句之后，所表述的理由是对某一事实进行推断。 例： 1) He thanked me for my help. 他因为我帮助了他而感谢。 2）The woman didn’t buy that coat for it is too expensive. 那位女士没有买那件上衣是因为它太贵了。 二、目的状语从句一般由in order that, so that来引导。二者都表示“以便、为的是”之意。此时，句中往往会用一些相关的情态动词来加以说明。 例： 1) I’ll have to run fast so that I can catch up with them in a short time. (目的) 我得快跑以便我能在短时间内赶上他们。 2) I opened the window so that fresh air could come in. (目的) 我把窗户打开以便新鲜空气可以进来。 3) We will tell you everything about it soon in order that you can prepare for that. 不久我们将会让你知道详情,以便你能够做准备。(目的) 三、结果状语从句通常由连词so…that, such…that引导。二者都表示“如此…以至于”之意。 例： 1) The teacher’s teaching was so interesting that all the students were very exc ited. 老师讲课非常有趣，学生们都感到很兴奋。
目的状语和目的状语从句 &让步状语和让步状语从句 I．目的状语和目的状语从句 so that，in order that，in case等词引导目的状语从句，so as to，in order to，in case of (doing) sth. 引导目的状语 e.g 1.

●原因状语从句 (1)原因状语从句通常由because, since, as,for引导。 (2)because表示直接原因，语气最强。because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。此外，because和so不能同用在一个句子里。 例如：------Why aren’t going there?------Because I don’t want to. since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴于……”。 例如：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散散步吧。 as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。 例如：As he has no car, he can’t get there easily. Since we have no money, we can’t buy it. (4)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。如: I decided to stop and have lunch, for I was feeling quite hungry. 小试牛刀： I was late for class yesterday _______ there was something wrong with my bike. He took off his coat _______ he felt hot. you can’t answer the question, I’ll ask som eone else. ●结果状语从句 (1)结果状语从句由so…that, such…that, so that引导。 (2)so…that语such...that可以互换。在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是: “...so + 形容词（副词）+ that + 从句”。 例如：He was so glad that he couldn’t say a word. Mother lives so far away that we hardly ever（几乎不，从来不） see her. 在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；其结构是: “...such +a / an + 形容词+名词+ that + 从句”。 例如：It was such a hot day that nobody wanted to do anything. He had such long arms that he could almost touch the ceiling.（天花板） 有时上述两种结构是可以互换的。 例如：It was such a wonderful film that all of us wanted to see it again. =The film was so wonderful that all of us wanted to see it again. (3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。 例如：Soon there were so many deer that they ate up all the wild roses. He has so little time that he can’t go to the cinema with you. （4）如果主从句的主语相同，并且从句是否定的形式，可以用too...to...句型转化。 例如：He was so excited that he couldn't go to sleep that night. = He was too excited to go to sleep.（5）如果主从句的主语相同，但从句是肯定的形式，可以用adj.+ enough替换。 例如：He is so old that he could go to school. = He is old enough to go to school.他够大了，可以去上学。 小试牛刀：It is ___ hot in the room ___ we have to go out for a walk.
