从句专项
在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、
副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
定语从句
定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。
定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例：
The woman who lives next door is a teacher.
先行词定语从句
在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词
宾语从句
宾语从句是英语复合句中的其中非常重要的从句之一。它是用一个句子做另一个句子的宾语，将这个句子叫做宾语从句。宾语从句做介词或及物动词的宾语。现在从下列三个方面总结归纳如下：
一，引导词
A,由that 引导的陈述句性的宾语从句，在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后。连词that 只起连接作用，在从句中不做句子的成分例：I told him that he was wrong.
l在think,believe, suppose, expect等动词引起的宾语从句中，有时谓语尽管是否定意义，却不用否定形式，而将think 等动词变为否定形式。
例：I don’t think you are right. (我认为你做的不对)
l在许多带有复合宾语的句子中，that引导的宾语从句经常移到句子的后面，而用it做形式宾语。
例：We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的)
B,由连词if、whether 引导的表示“是否…”的宾语从句。Whether,if 在从句中不做句子的成分，一般情况下，whether和if 可以替换。
例：I don’t know if/whether he will co me tomorrow.
The teacher asked if/whether we had finished the experiment.
l在介词后面的宾语从句中不用if引导
例：Everything depends on whether we have enough money。
l宾语从句中有or not时不用if引导.
例：I don’t know whether the movie star will come or not.
l和不定式连用作宾语时不用if引导.
例：Whether to go there or not hasn’t been decided.
C,由wh-引导的宾语从句。连接代词who,whom,whose, what, which,和连接副词when, where, why, how 等连接的宾语从句，它们在句中即有连接从句的作用，又在句中充当句子的成分。
例：Do you know which film they are talking about? (which做定语)
I don’t know where he lives. (where 做地点状语)
二，宾语从句的语序，
宾语从句从句的语序必须是陈述语序，既连接词+主语+谓语+其他成分
例：I believe that they will come soon.
He asked me whether I was a teacher.
They wanted to know what they can do for us.
二，宾语从句的时态。
宾语从句的时态受主句的限制，
既：主句是一般现在时态，从句根据实际情况而定。
主句是一般过去时态，从句用相应的过去的时态。如果从句的动作发生在主句之前，则从句要用过去完成时态。
例:
1)She says that she is a student.
She said that she was a student.
2)She says that she will fly to Japan in a week.
She said that she would fly to Japan in a week.
3)She says that she has finished her homework already.
She said that she had finished her homework already.
4)She says that she can sing a song in English.
She said that she could sing a song in English.
l如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。
例：The teacher said that the earth goes round the sun.
He told me that Japan is an island country.
lCould you tell me…是用来征询对方的意见，语气委婉，并不表示过去。
例：Could you tell me when we will visit the Histury Museum?
C、同位语从句
(一) 概念
一般来说，在主从复合句中,用作同位语的从句叫同位语从句。它通常跟在某些名词之后，用以说明或解释该名词表示的具体内容。
可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word（消息），problem，question, doubt, thought等。例如：
They were delighted at the news that their team had won.
当听到他们队获胜的消息时，他们欣喜若狂。
Where did you get the idea that I could not come？你从哪儿听说我不能来？
有时同位语从句可以不紧跟在被说明的名词后面，而被别的词隔开。如：
The thought came to him that Tom might have returned the book.
他突然想起汤姆可能已经还了书了。
（二）引导词
[寻规找矩] 请仔细观察下列句子，注意从句引导词的用法。
1. The news that Mr. Li will be our new English teacher is true.
2. He hasn’t made the decision whether he will go there.
3. The question who should do the work is being discussed at the meeting.
4. I have no idea what the boy is doing in the next room now.
5. We haven’t yet settled the question where we are going to spend our summer vacation this year.
6. I have no idea how I can get to the railway station.
7. I have no idea when he will be back．
[小结归纳]
①that引导同位语从句时无词义，也不充当任何成分，但通常不可以省略，如句1；
②whether引导同位语从句时意为“是否”，通常不能用if来代替,如句2;
③连接代词who, what等可以引导同位语从句，如句3，4；
④连接副词where, how, when等可以引导同位语从句，如句5，6，7。
(三) that 引导的同位语从句和定语从句
①意义不同：同位语从句用来进一步说明前面名词的内容；而定语从句用来修饰、限定前面的先行词。试比较：
1. The news that our team has won the final match is encouraging.
2. The news that you told us is really encouraging.
[分析] 句1中that引导同位语从句，说明“news”的内容：我们队取得了决赛胜利。句2中that引导定语从句，对“news”加以限定：是你告诉我们的，而非来自其他渠道。
②that的功能不同：that引导同位语从句时是一个纯连词，不充当任何成分；而引导定语从句时，不仅起连接作用，而且还指代先行词并在从句中充当主语、宾语等成分。试比较：
1. Dad made a promise that he would buy me a CD player if I passed the English test.
2. Dad made a promise that excited all his children.
[分析] 句1中that引导同位语从句，其中that无词义，也不充当任何成分；
句2中that引导定语从句，that指代promise，又在从句中充当主语，且that可以用which替换。
③可否省略：that在引导同位语从句时，通常不可省略。在引导定语从句时，若在从句中作宾语，通常可以省略，若作主语则不可以省略。

D、状语从句的种类
§ 1状语从句的种类
用来修饰谓语动词、其它动词、定语、状语或整个句子的从句叫做状语从句。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.条件状语从句；
5.目的状语从句；
6.让步状语从句；
7.比较状语从句；
8.程度状
语从句；9.方式状语从句；10.结果状语从句。
§2状语从句的时态特点
一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。
二时间状语从句
§3时间状语从句（adverbial clause of time）
1.由when, while, as引导的时间状语从句。
【区别】when, while和as的区别：when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。
While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如：
While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生)
As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。
As we was going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）
2.由before和after引导的时间状语从句。注意before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，
有时译成“就，才”。还要注意主句和从句之间的时间关系。当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和从句的动作的时间关系正好与before引导的从句相反。
3.由till或until引导的时间状语从句。till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主
句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。例如：
4.由since引导的时间状语从句。since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。一般情况下，从句谓语动
词用一般过去时，而主句的谓语动词用现在完成时。但在It is ＋时间＋since从句的句型中，主句多用一般现在时。例如：
5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。这些连词都表示
“一……就”。
【注意】hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意。主句用过去完成时，从句用一般过去时。
当hardly, scarcely, rarely和no sooner位于句首时，主句应用倒装语序。
6.由by the time引导的时间状语从句。注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过
去完成时；如果主句的谓语动词用一般现在时，主句的谓语动词用将来完成时。
7.由each time, every time和whenever引导的时间状语从句。
8.由as long as和so long as引导的时间状语从句。这两个连词表示“有多久……就多久”。
三地点状语从句
§4地点状语从句(adverbial clause of place)
地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，例如：
句型1：Where＋地点从句，（there）＋主句。
【注意】此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。
句型2：Anywhere/ wherever＋地点从句，＋主句。
状语从句是句子的状语由一个从句充当，来修饰主句中的动词，形容词或副词等。状语从句都由从属连词引导，与主句连接，放在句末时，一般不在前面加逗号。
状语从句根据它表示的意思可分为时间，原因，条件，比较，结果，目的等类。
时间状语从句：是由when, as, while, after, before, since, until, as soon as 等从属连词引导的状语从句。
时间状语从句中的谓语动词不能用一般将来时，只能用一般现在时表示将来发生的动作或存在的状态。
原因状语从句：because, since, as和for都表示原因。because语势最强，回答why提出的问题，用来说明人所不知的原因。当能够很明显的看出原因或人们已知原因，就用as或since。
由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
目的状语从句：表示目的状语的从句可以由in order that, so that,等词引导。
结果状语从句：结果状语从句常由so...that 或such...that引导，要掌握和区分这两个句型，
首先要了解so和such后面分别跟什么词。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。
如：The box is so heavy that I can't carry it.
让步状语从句：是由though, although 引导的状语从句。
E、表语从句
表语从句就是用一个句子作为表语。说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。
表语从句只能置于主句之后，而主句的动词只能是联系动词。
名词性从句在be等系动词后作表语时被称为表语从句，例如：The problem is how we can get the things we need.
问题是我们怎样能弄到我们需要的东西。(how 在表语从句中充当方式状语)// The scissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语)// What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语，that作为表语从句的引导词在该表语从句中不充当句子成分，
不能省略)// That is what I want to tell you.那就是我想要对你讲的。(what在表语从句中充当直接宾语)// That is why she failed to pass the exam. 那就是她考试不及格的原因。(why 在表语从句中充当原因状语)
“That is why...”是常用句型，意为“这就是……的原因/因此……”，其中why引导的名词性从句在句中作表语，该句型通常用于针对前面已经说明过的原因进行总结，又如：That is why you see this old woman before you know, Jeanne. 珍妮，这就是现在这个老太婆出现在你面前的原因。(前文提到Jeanne对老妇人显得苍老憔悴深感诧异，说话人对她讲述了其中的原因之后，用这一句来进行概括)。// That is why I came. 这就是我来的原因。
下面是两个与“That is why...”形式相似的结构，它们与“That is why...”结构之间的关系要能够辨析清楚：
(1)“That is why...”与“That is the reason why...”同义，只不过从语法结构上讲，“That is the reason why...”中why 引导的是—个定语从句，将其中的the reason去掉则与“That is why...”结构一样，例如：
That is (the reason) why I cannot agree. 这就是我不能同意的理由。
(2)“That is because...”句型中从属连词because引导的名词性从句在此作表语，这也是个常用句型，意为“这就是为什么……/因为……”。“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果，例如：
He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影，那是因为他得帮助他的妹妹做作业。(第一句话说明结果，第二句话说明原因)
He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影，因此他昨天晚上没有去看。(第一句话说明原因，第二句话说明结果)
［考题1］
The traditional view is ____ we sleep because our brain is “programmed” to make us do so. (2007上海)
A. when
B. why
C. whether
D. that
［答案］ D
［解析］下划线处之后是包含一个原因状语从句的表语从句，如果看不出它是充当整个句子结构的表语从句将难以把握整个句子的意思。因此，应选择可引导名词性从句且不充当任何成分的that。
［考题2］
You are saying that everyone should be equal, and this is ____ I disagree. (2004)
A. why
B. where
C. what
D. how
［答案］ B
［解析］下划线处的引导词引导系动词is后的表语从句并在该表语从句中充当地点状语(“disagree”属于不及物动词，“I disagree”本身是完整的主谓结构)，下划线应填入引导词where，表语从句“where I disagree”的意思是“我不同意之处、我不同意的地方”。
［考题3］
— I drove to Zhuhai for the air show last week.
— Is that ____ you had a few days off? (1999)
A. why
B. when
C. what
D. where
［答案］ A
［解析］下划线处的引导词引导与系动词is连用的表语从句并在该表语从句中充当原因状语，下划线应填入表示“因此……”(指因某种原因所造成的结果)的引导词why。
状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词（从属连词）引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。 一、时间状语从句 要点: 时间状语从句，由以下连词引导： whe n while as after before as soon as since till /un til by the time在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。 1. whe n当。。。的时候 mozart started writing music when he was four years old. （当）莫扎特的时候，开始写音乐作品。 2. while 当。。。时 he visited a lot of places while he was traveling. 他在旅途中参观了许多地方。 3. as在。。。的同时；一边。。。一边。。。 he smiled as he stood up. 他一边站起来一边笑着。 4. after 在。。。之后 he left the classroom after he had finished his homework the other day. 前几天做完作业之后回的家
5.before 在。。之前 mr. brown had worked in a bank for a year before he came here. 布朗先生来这之前已经在一家银行里工作一年了。 6. as soon as o。。就。。。 we began to work as soon as we got there. 我们一到那就开始工作。 i will write to you as soon as i get home. 我一到家就给你写信。 7. since 自。。。以来到现在 表示自过去的一个起点时间到目前（说话时间）为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。 mr green has taught in that school since he came to china three years ago. 自格林先生来中国以来，他就在这所学校教书。 （还可以用作介词，本句从句还可以用短语：si nee three years ago自三年前以 来）表示。） 8 till /until 都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。 they walked till /until it was dark. 他们一直走到天黑 xiao ming didn 't leave home till /iluhnits father came back.
初中英语语法——三大从句汇总 在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即 状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句（attributive clause），顾名思义，就是一个句子作定语从属于主句。定语一般是由形容词充当，所以定语从句又称作形容词从句。另外，定语从句是由关系代词或关系副词引导的，故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后，这种名词或代词被称作先行词。请看示例： The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词，并且在定语从句中充当句子成分，可以作主语、宾语、定语等。常见的关系代词有：who, that, which。它们的主格、宾格和所有格如下表所示： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （一）关系代词who, whom和 whose的用法 who代替人，是主格，在定语从句中作主语。例如： An architect is a person who designs buildings. 建筑师是设计房屋的人。
I will never forget the teacher who taught us chemistry in the first year of my senior middle school.我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。whom代替人，是宾格，在定语从句作宾语，在非正式英语常可省略。例如：Do you know the gentleman whom we met in the school library yesterday? 昨天我们在学校图书馆里遇到的那位先生你认识吗？ This is the student whom my father taught ten years ago.这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） whose一般代替人，有时亦可代替物，是所有格，在定语从句作定语。例如：The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。 Do you know the name of the hotel whose window we can see here? 我们这儿能看到窗户的那个宾馆叫什么名字，你知道吗？（关系代词whose指代先行词hotel，正式用法应该用of which。whose window=the window of which，意思是：the window of the hotel。） （二）关系代词which的用法 which代替物，在定语从句作主语或宾语，作宾语时还可省略。例如： I do not like stories which have unhappy endings. 我不喜欢有不幸结局的小说。（which可以换成that） Tom works for a factory which makes watches. 汤姆在一个制表厂工作。（which可以换成that） （三）关系代词that的用法 that既可指人又可指物，在当代英语中大多指物，在定语从句作主语或宾语，作宾语时还可省略。例如： Is she the girl that sells newspapers? 她是卖报纸的那个女孩吗？（that可以换成who） Where is the ice-cream that was in the fridge?
语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同，可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样，状语从句的位置比较灵活。既可置于主句之前（通常用逗号与主句隔开），也课置于主句之后（不需要用逗号与主句隔开），有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生，这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思 他继续往下谈的时候，越来越兴奋。 as还可以表示一边??一边??，强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来，天气暖和起来。 ② when 强调动作点的特定时间，具有at the time that 的意思 当老师走进来的时候，我们都站起来了。 ③ while 表示较长的期间，具有during the time that 的意思 当我在这的时候，我很安全。 2.主句发生在从句之前，这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”，在否定句中意为“直到 --- 才”。从句既可置于主句前，也可置 于主句之后。 回家之前我必须干完所有的活。
时间状语从句 要点: 时间状语从句，由以下连词引导： when while as after before as soon as since till /until by the time 在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。 当。。。的时候 mozart started writing music when he was four years old. (当)莫扎特的时候，开始写音乐作品。 当。。。时 he visited a lot of places while he was traveling.他在旅途中参观了许多地方。 在。。。的同时；一边。。。一边。。。 he smiled as he stood up.他一边站起来一边笑着。 在。。。之后 he left the classroom after he had finished his homework the other day. 前几天做完作业之后回的家。 在。。。之前 mr. brown had worked in a bank for a year before he came here. 布朗先生来这之前已经在一家银行里工作一年了。 soon as 一。。。就。。。(主将从现) we began to work as soon as we got there.我们一到那就开始工作。 i will write to you as soon as i get home.我一到家就给你写信。 自。。。以来到现在 表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。 mr green has taught in that school since he came to china three years ago. 自格林先生来中国以来，他就在这所学校教书。 (还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。) 8 till /until都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。 they walked till /until it was dark.他们一直走到天黑。 xiao ming didn’t leave home till / until his father came back.小明直到他爸爸回来才离开家。 9. by the time 到。。。为止 (所在句子的主句应用完成时) by the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。 by the time i got to school, the class had already began.我到校时，已经开始上课了。 难点——as when while的辨析 as when while都表示主、从句动作同时发生，三者差异如下： as 表示“一边。。。一边＂的意思 强调两个动作同时进行，并表示对比时 when 1、还可以表示从句动词的动作在主几句动词的动作＂之前＂或＂之后＂发生。 2、when＝and then; at that moment (正在那个时候)

初中英语状语从句知识点总结（一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。 如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。

状语从句 状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状 语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让 步状语从句。 1. 时间状语从句 ⑴时间状语从句常用when, as, while, before, after, since, till, until, as soon as 等连词来引导。例如： It was raining hard ( rain hard 下大雨) when got to school yesterday. While he was doing his homework, the telepho ne rang. As he walked along (沿着走) the lake, he sang happily. He had lear ned a little Chin ese before he came to China. After he finished middle school, he went to work in a factory. (2) 在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I ' ll ring you up as soon as I get to New York. I will tell him everyth ing whe n he comes back. He won ' t believe it until he sees it with his own eyes. (3) 在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是一直到……时” 谓语动词只能用延续性动词。如果主句用否定式，其含义是直到……才……”,在…??…以前不……”,谓语动词可用瞬间动词。例如： The young man read till the light went out (熄灭) Let ' s wait until the rain stops. We won' t start until Bob comes. Don' get off (从下来) until the bus stops. 【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止 (不怎么可能持续)。固定组合里from morning till night，till/until是不能替换的，】 2. 条件状语从句 (1) 条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don' t leave the buildi ng uni ess I tell you to. (2) 在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I ' ll helyou with your English if am free tomorrow. He won ' t be late uni ess he is ill. (3) 祈使句+ and (or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you ' ll be=iayau don ' t hurry up, you ' ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如：
