原因结果目的状语从句讲解和练习答案

●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.

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.

He is so young that he couldn’t go to school.= .

The classroom is so big that it can hold 100 person. = .

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)

原因、目的、结果状语从句讲练

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。

I am taking an umbrella so that I will not get wet. I am taking an umbrella in order that I will not get wet. e.g.1. We were not tired though (although) we had worked all day. 虽然我们干了一天活，但并不累。 2.

状语从句用法讲解和练习

第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下: 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有：2．when，while，as均可表示“当……的时候”。 when强调“特定时间”，表示主句谓语动词的动作与从句谓语动词的动作是同时发生的，或从句的动作发生在主句的动作之前；while表 示的时间是一段，而不是一点，as多用在口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom．(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生，但三者也有

区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如： 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如： He looked behind from to time as he went.他一边走，一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.） 当主从句之间表示转折或对比关系时，多用while, 不用as或when。如：

状语从句 状语从句修饰主句/主句的谓语。一般有九大类：表示时间、地点、原因、目的、结果、条件、让步、比较和方式等。 时间状语从句 1. 用when引导：when表示“当……时候”。如： Things were different when I was a child. 我小时候情况与现在不同。 People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢。 2. 用while引导：while表示“当……时候”。如： We must strike while the iron is hot. 我们要趁热打铁。 I went swimming while the others played tennis. 我去游泳，其余的人都打网球去了。 注意：while 所引导的时间状语从句中谓语动词必须是持续性的，不能是短暂性的。 3. 用as引导：as表示“当……时候”“随着”。如： He dropped the glass as he stood up. 他站起来时，把杯子摔了。 We get wiser as we get old. 随着年岁的增长，我们也变得聪明些了。 4. 用before引导：before表示“在……之前”。如： Turn off the lights before you go to bed. 睡觉前要关灯。 Before he went to university he was a worker. 上大学之前他是工人。 5. 用after引导：after表示“在……之后”。如： I will tell you after they leave. 他们走我再告诉你。 After you finish the letter show it to me．信写完后给我看看。 6. 用until / till引导：until / till表示“直到……”。如： He waited until she was about to leave. 他等着一直到她准备离开。 I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失。 这类句型的主句动词通常只能是延续性动词，不能是终止性动词。但是，在否定句中，主句动词可以是终止性动词，此时构成not…ntil [till]…句式，意为“直到……才……”。如：

初中英语知识点总结目的状语从句

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

原因、结果、目的状语从句讲解和练习(答案)

●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.
