专题四——状语从句
英语中的状语从句用来修饰谓语或者整个主句按照功能可以分为：时间状从，地点状从，原因状从，结果状从，条件状从，目的状从，让步状从，方式状从，比较状从。
1、时间状语从句
（1）when、while、as用法一览表。
（2）引导时间状语从句的连接词除上述外还有：
①as soon as ，directly, immediately, the moment, the minute … 一……就
As soon as I have finished it , I’ll give yu a call.
He made for the door directly he heard the knock.
②h ardly / scarcely … when, no sooner … than,
表示“一……就”
We had hardly got / Hardly had we got into the country when it began to rain.
No sooner had he arrived / He had no sooner arrived than she started complaining.
③till, not … until …, until, before, since before 用法not until 强调，倒桩since用法
Don’t get off the bus until it has stopp ed. Not until years later could I realize the value of that kind of giving.
He waited for his father until(till)it was twelve o’clock.It was not until years later that I could realize the value of that kind of giving
It is/ has been +一段时间+since从句非延续，自。。。以来，已经有。。。年。
区分：It is two years since he began to smoke.
It is two years since he smoked
肯定句：一段时间，距离+before 过了多久才？
It will be five years before he returns from England. Before :1
和we waited along ime ,before he came out.
.否定句一段时间、距离+ before 过不了多久就It won’t be five years before he returns from England.
还没有，还没来得及，免得he died before he wrote a wil l.I must write it down before I forget,.
④each time, every time, by the time
Each time he came to my city, he would call on me.
注意：表示未来情况，主句用将来时，从句用现在时。
2、地点状语从句：where, wherever
Make a mark wherever you have any questions.
We will go where the Party directs us.
3、原因状语从句：because,, as, since=now that
（1）表示不知道的原因时用because,即说话人认为听话人不知道，因此because从句是重要的部分，通常它被置于主句之后。You want to know why I’m leaving? I’m leaving because I’m full.
for虽然表示不知道的原因，但其语气较because要弱得多，是可说可不说的话，它只能置于主句之后，这时，for是并列连词。如：It’s morning now, for the birds are singing.（很显然，鸟叫不可能是“现在已是早上”的原因。）
（2）表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since要比as正式一些，它们通常被置于语句之前。
Seeing all of the children already seated, he said,“S ince everyone is here, let’s start.”
Nowthat/Since no one is against art,, let’s carry out the plan.
4. 条件状语从句：if, unless, so (as) long as, on condition that. in case, once一旦注意if与unless的区别
In case anything important happens，please call me up.
My parents don't mind what job I do as long as I am happy.

_______ you start eating in a healthier way, weight control will become much easier.

高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。
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。
思维导图 易考易错点总结 状语从句包括时间状语从句、地点状语从句、条件状语从句、让步状语从句、原因状 语从句、目的状语从句和结果状语从句。 对状语从句的考查主要集中在连接词上， 尤其要重 视as, until, before, since, when, in case 等连词的各种语义功能和语法功能。具体来说主要包 括： 1考查状语从句的连接词。要掌握各个连词的含义及其用法，还有它们之间的区别。 如: 时间状语的连词有 while, when , as , as soon as until , not …until , before, after, since 等；条件状语从句的连词有 if , uni ess, in case, on con diti on that, provided (that), suppos ing, suppose (that)等；结果状语从句的连词有 so …that(如此 .... 以至于),such …that(如此 ...... 以 至于)等。 2 ?考查固定搭配和习惯用法的连接词。 女口： no soon er …tha n …，hardly …whe n …，scarcely …before …，the mome nt/minute , directly 。 3. 考查不同性质的连词在不同的语境中所表达的不同意义。 女口： as 既能引导时间状语从句，又能引导原因状语从句和让步状语从句； where 能引导 地点状语从句和定语从句等。 4. 考查状语从句的时态。 主要考查在时间、条件、让步状语从句中用一般现在时表将来及用一般过去时代替过去 将来时的用法。 5. 考查状语从句的省略。 状语从句
被动语态、条件状语从句和让步状语从句 李仕才 课程目标 一、学习目标 1. 条件状语从句及其连词的用法。 2. 让步状语从句及其连词的用法。 3. 被动语态。 二、重点、难点 重点：条件状语从句、让步状语从句及被动语态。 难点：让步状语从句和名词性从句的区别。 三、考情分析 这三种语法是高考考查的重点语法，历年考题中占有重要的地位，一般能在单选中占3-4分；在完形填空中也能占2-3分；我们复习时要特别注意这几种语法及其做题技巧，认真研究近几年的高考题。 知识梳理 一、条件状语从句 【教材原句】 If you say the word “communication”, most people think of words and sentences. 如果你说单词“交流”，大部分人会想到单词和句式。 If our right hand is busy greeting someone, it cannot be holding a weapon. 如果我们的右手忙着问候别人，它就不可能握有武器。 考点1引导条件状语从句的从属连词 【用法】 连接词主要有if, unless, as/so long as, on condition that, provided, suppose, supposing 等。 【例句】 You can leave now if you like. 如果你愿意现在就可以走了。 As long as it doesn’t rain we can go.
只要不下雨，我们就可以去。 In case I forget, please remind me about it. 万一我忘记，请提醒我一下。 I will come on condition (that) she is invited too. 如果邀请她来, 那我就来。 He may go with us provided [providing] he arrives in time. 他若及时到达，就可以和我们一起走。 【考题链接】 they decide which college to go to, students should research the admission procedures. A. As B. While C. Until D. Once 答案：D 解题思路：句意：一旦他们决定去哪个大学，学生就应该搜索入学手续。once 一旦，根据句意选择D。 考点2条件状语从句的时态 【用法】 当主句为将来时态或具有将来意义时，条件状语从句通常要用一般现在时表示将来意义，而不能直接使用将来时态。 【例句】 Let’s go out for a walk unless you are too tired. 如果你不是太累的话，让我们出去散步。 I’ll stay at home if it rains tomorrow. 要是明天下雨，我就呆在家里。 【考题链接】 We will be losing money this year unless that new economic plan of yours _______ well. A. is working B. works C. will be working D. worked 答案：B 解题思路：句意：如果你的那个新经济计划效果不好的话，我们今年会失去很多钱。在条件状语从句中，如果主句用一般将来时态，那么从句用一般现在时态表示将来意义。 考点3if 引导的条件句有真实条件句和非真实条件句两种 【用法】 真实条件句表示现实情况中可能实现的情况。非真实条件句也叫虚拟条件句，表示与现实情况相反的假设情况。 【例句】
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. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，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和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard. 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
