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。

A．so that B．because of C．until D．as soon as 【答案】A 【解析】
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。
高中英语条件状语从句的句型 在高中英语的学习中，学生会学习到很多的重要的句型，下面本人的本人将为大家带来条件状语的句型的介绍，希望能够帮助到大家。 高中英语条件状语从句的句型介绍 1条件状语从句 句型1 When / So long as / As long as / Once +从句，+主句。(从句也可以放在主句之后。)如： As long as you give me any money, I will let you go.只要你给我一些钱，我就让你走。 Once you have begun to learn English, you should learn it well. 一旦你开始学习英语，你应该把它学好。 句型2 主句+on condition that+从句.如： I will go with you on condition that you give me a sum of money.我和你一起去的条件是你给我一些钱。 句型3 主句+unless+从句.(注意：由于unless本身是否定词，所引导的从句的谓语动词用肯定而不用否定。)如： I will go there tomorrow unless it rains.我明天去那儿除非下雨。 点击查看：高中英语语法大全 句型4 祈使句，+and/ and then+主句。(注意：祈使句也可
用一个名词短语。)如： Use your head, and you will find a good idea.动脑筋想一想，你就会想出一个好主意。 Another word, and I will beat you.你再说一句，我就揍你。 句型5 If +necessary / impossible/ important等，+主句.(注意：if与形容词之间的it is被省略。)如： If necessary, I will do it. 如果有必要的话，我来做此事。 2原因状语从句 句型1 主句+in case+从句.(in case表示以免)如： I will take my raincoat in case it rains.我要把雨衣带上以免下雨。 句型2 主句+due to / because of / owning to / + the fact that +从句。如： He did not come to school because of the fact that he was ill.由于他有病了，所以没有来上学。 高中英语 以形式主语it引导的句型 句型1 It (so) happened(chanced) that +clause. = sb. happened /chanced to do sth. =sb.did sth. by chance. 如： It happened that he was out when I got there.
初中英语状语从句解析版汇编含解析 一、初中英语状语从句 1．_______it’s a public holiday today, some firefighters in our city are still on duty. A．Although B．Once C．If 【答案】A 【解析】 【详解】 句意“尽管今天是公共节假日，但是我们城市的一些消防员仍然在岗位值班”。A.尽管（引导让步状语从句）；B.一……就……（引导时间状语从句）；C.如果（引导条件状语从句）。根据句意可知，今天是公共假日，本应该休息，但是消防员仍然在岗值班，表示让步，故选A。 2．— _______ good time we had at the party last night! — Yes. It was _______exciting party that I would never forget it. A．What; so B．How; such C．What a; such an D．How a; so an 【答案】C 【解析】 【详解】 试题分析：句意：昨天晚上我们在聚会上玩的是多么开心呀！是的，它是如此的令人兴奋以至于我永远不会忘记它。 第一句为感叹句，是对 a good time表示感叹，time为名词，所以用what来引导，第二句考查such+a/an+adj+n.+that句型结构，表示“如此……的一个东西……以至于”，故选C。 3．-Have you improved your spoken English？ -Not yet．I'll try my best______I am not good at it now． A．so B．although C．but D．until 【答案】B 【解析】 【详解】 句意：——你提高你的英语口语了吗？——还没有．虽然我现在还不擅长，但是我会尽力的．考查连词辨析。A. so所以；B. although 虽然；C. but但是；D. until直到。根据语境推测句意是——你提高你的英语口语了吗？——还没有．虽然我现在还不擅长，但是我会尽力的．在这里两个句子之间存在一个相反的让步关系，though/although/even though“虽然；尽管”，引导让步状语从句，故选B． 【点睛】 本题主要考查连词的用法，连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词．前后句之间是让步关系．
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
条件状语从句 概念定义 由引导词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。（注意：在含有条件状语从句的复合句中，表示将来时态，主句是一般将来时态,祈使句或情态动词，从句要用现在时态,[主将从现原则]（主将从现，将并非指将来时，还指表示将来含义的，跟着if后的那句话是从句。） 类型 条件状语从句 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如： 1） If you ask him,he will help you. 如果你请他帮忙，他会帮你的。 2） If you fail in the exam,you will let him down. 如果你考试不及格，你会让他失望的 if引导的条件状语从句既可以将从句放前面也可以将从句放后面 （如果天下雨，我们就不玩了）If it rains,we will stop playing.‘ 转为We will stop playing if it rains. if引导的条件状语从句
另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设，从句多用一般过去时或过去完成时。如：If I were you,I would invite him to the party.如果我是你，我会邀请他参加聚会。I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车，我会到的早一点儿。 那么，除了if之外，是否还有其他连词也可以引导条件状语从句呢?回答是肯定的，不仅有，还有很多。这些词由于出现的频率较小，且用法较复杂一些，所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非，若不，除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身，你就不能及时赶到那儿。 Unless it rains,the game will be played.除非下雨，比赛将照常进行。 2、on condition(that)...在……条件下，如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相，条件是你答应保密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果，假如 supposing引导的条件从句表示一种假设条件。 Supposing it rains,shall we continue the sports meeting?倘若下雨，我们的运动会还要继续举行吗? Supposing anything should go wrong,what would you do then?假如出了什么问题，你准备怎么对付?
状语从句用法详解 内容提要： 一、时间状语从句 二、地点状语从句 三、方式状语从句 四、程度状语从句 五、原因状语从句 六、结果状语从句 七、目的状语从句 八、条件状语从句 九、让步状语从句 十、比较状语从句 一、时间状语从句: 1、时间状语从句通常用下列从属连词来引导：after, before, as, once, till, until, (ever) since, when, whenever, while, now (that), as long as, as soon as。如： Now (that)you’ve gr own up, you must stop this childish behaviour. Whenever we met with difficulties, they came to help us. Come and see us whenever you have time. People do not know the value of health till they lose it. 2、有些词，如immediately, directly, instantly 等，当用于as soon as 意义时，也可以引导时间状语从句，如：
I got in touch with him immediately I received his letter. My sister came directly she got my message. The machine will start instantly you press the button. I’ll t elephone you directly I hear the news. Will you look for it immediately you get there? 3．某些表示时间的名词词组，如the (very) moment ( = as soon as ), the minute ( = as soon as ), the instant ( = as soon as ), the day, the year, the morning, every time, each time, next time, the first time 等，也可以引导时间状语从句，如： I’ll tell you about it the moment you come. I started the instant I heard the report. The instant she saw him she knew he was her brother. Every time I catch a cold, I have pain in my back. I’m going to see him next time he comes to Shenzhen. He left Europe the year World WarⅡbroke out. He had impressed me that way the first time I met him. I started the very moment I got your letter. I’ll tell him the minute (that) he gets here. 4．有些关联从属连词，如no sooner …than / hardly …when / scarcely …when / barely …when 等，也能引导时间状语从句。 △如果把no sooner, hardly, scarcely, barely 置于句首，它所连带的这部分就要倒装，如：
状语从句 一：状语从句的定义、功能、分类 定义：在复合句中作状语的从句 功能：状语从句在主从复合句中修饰主句中的动词，形容词或副词，或整个主句 分类：按意义可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。位置：从句的位置放在句首，也可放在句末。放在句首时，从句后面常用一个逗号，放在句末时，从句前一般不用逗号。 二：考点与难点 1、各种从属连词的含义及用法比较； 2、no matter wh- 与wh-ever 引导的从句的区别； 3、状语从句的时态问题； 4、状语从句倒装及省略； 5、状语从句与其它从句的区别。三：九种常见状语从句用法 1. 时间状语从句 引导时间状语从句的从属连词 1）.基本类：before、after、when、while、as、since、till、until、once, as soon as, etc. 2）. 名词类 the moment ,the minute, the second, the instant,etc. (一…就…); every time, each time, the last time, the first time, the day, the year, the morning etc. 3）. 副词类：immediately, directly, instantly, etc. (一...就...) 4）.句型类：no sooner…than…, hardly/scarcely…when…, etc. (一…就…) 注意：1. when, as, while When ①when表示时间点时，从句中用短暂性动词；表示时间段时，用持续性动词。Eg:. When they were still talking and laughing, the teacher came in. （when表示段时间） 2). He waved a hello when he saw her.（when表示点时间） ②. 可用作并列连词，其意义为“这时,突然”，相当于and then suddenly。常用于下列句式： be doing / be about to do sth/ be on the point of doing / have/had done + when Eg.1). I was about to go out when the door bell rang. 2). One evening I was having my dinner when an unexpected friend knocked my door. ③. 还可以表示原因,意思是“既然”，相当于since; considering that Eg. 1).

While they love the children, they are strict with them. As ①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。 eg: She is singing a song as she took a bath. ②as表示随着 eg: As time goes on, it's getting warmer and warmer. 2. till, until和not…until 1）until /till用于肯定句时，表示直到…为止，主句必须为持续性动词。
