语法状语从句 由从句担任的状语,在句子中可修饰谓语(或其它动词)、形容词、副词或就是整个句子,它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。 第一讲时间, 地点状语从句 时间状语从句:when, while, as, before, after, since , whenever until, till, by the time(注意时态) as soon as, had hardly…when, had no sooner…than,(on doing sth…) the moment, every time/ each time, the first time, once e、g: When he came, I had cleaned the classroom、 He didn’t stop working until his mother came bake、 He worked until his mother came back、 As soon as he returned, he bought a new flat、 He had no sooner returned than he bought a new flat He came to scene the moment he heard the news、 I thought her nice and honest the first time I met him、 Once he makes up your mind, he won’t change his mind、 It was two years before I met him again、= Two years passed before I met him again、注意点1、when引导的从句动词可以就是延续性的或短暂性的,while引导的从句中动词必须就是延续性的; while有时并不表示时间,而表示对比,表示“而”、“却”。 When I got home I found the door locked、 While(或When)we were working in the fields, it suddenly began to rain、 His pencil is red, while mine is yellow、 2、till与until not…until/till 解释为直到…才…主句动词一般就是短暂性的 …till/until… 解释为直到…为止主句动词一般就是延续性的一般情况下可以互换,但until可以位于句首,till则不能。 He worked until it was dark、 He didn’t stop working until it was dark、 Until it stops raining,the children can’t go out、 ＝Not until the rain stops can the children go out、 地点状语从句 引导地点状语从句的连词就是where 与wherever等。 I ll go wherever the people want me to go、(wherever＝to any place where) He works where his grandfather fought、(where＝in the place where) You must stay where you are、= You must stay in the place where you are、 Wherever you go, I go too、 Where there is water, there is life、(那儿有… 那儿就有… Where there is a will, there is a way、) 圈出其中的从句并翻译: 1.Whenever it is his turn to speak, he gets nervous、 2.Every time he comes, he always tells us something interesting、 3.When I get the news, I will let you know as soon as possible、 4.Once he makes a promise, he will never break it、 5.I had no sooner run into the school gate than I heard the bell for class、 6.I found the lost watch under a desk after the children had left for home、 7.He had to be called two or three times before he came down to dinner、 8.We didn’t notice anything wrong with the washer until we started using it、 9.The hunter made mark on the tree where he stops、 10.Wherever he is, he will find time to do some reading、
状语从句 在复合句中担任状语成分的从句称为状语从句，修饰主句的谓语动词，形容词或副词，状语 说白了就是修饰动作的词或句，也可以理解成修饰谓语的词或句。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） 状语的位置比较灵活，可以位于句首、句末或句中。enough 用作状语修饰形容词和副词时 必须后置。 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，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 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, every time, the day ， the instant, immediately , directly, no sooner ? than, hardly ? when, scarcely ? when I didn ’ t realize how special my mother was until I became an adult. While John was watching TV , his wife was cooking. The children ran away from the orchard( 果园 ) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: When I arrived home , I had a little rest. 注意点： when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be 可以省略。Eg: When (she was) walking along the street, she met her class teacher. 2) As As 除了表示“当```的时候”，还可表示为“一面``` 一面”，“随着” Eg: He sang as he danced.(一面 ```一面 ) You will grow wiser as you grow older.(随着) 3) While 表示“当 ``` 的时候” 强调主句的动作和从句的动作同时发生，从句一般用进行时， 从句动词必须是延续性动词。 Eg: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1．until, not ? until 表示“直到 ```才” ,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
教学内容状语从句 教学目标常考状语从句的用法 状语从句 定义：在复合句中修饰主句中的动词、形容词或副词等的从句叫做状语从句。状语从句根据它表示的意思的不同可分为时原因、结果、让步、比较（或方式）和条件等类。 一. 掌握原因状语从句： 常用引导词：because（因为）; since（既然）; as（由于） 1. 既然大家都在了，我们开始上课吧 ____________ everybody is here, let’s ___________ our class. t be able to understand what you say, ___________ you speak too quickly. 2. I won’ A. because of B. though C. because D. so 二. 掌握结果状语从句： 常用引导词：so……／so…that…/such…that… 常用句式：(1) …so adj./adv. + that从句 (2) … such + a/an + adj. +可数名词单数+that从句 (3) …such + adj. + 可数名词复数+that从句 (4) …so + adj. + a/an + 可数名词单数+that从句 1. Durian 是如此的美味，很多人都很想吃。 Durian is __________ __________ __________ many people would like to eat. 2. Kelly 是如此细心的一个女孩，她在作业上几乎不会犯错。 Kelly is __________ __________ _________ girl __________ she hardly makes mistakes in her homework. 注意：※so many/much/few/little 已成固定搭配，不能换成such。 三. 掌握时间状语从句： 常用引导词: before, after, when, while, as, as soon as, since, not…until... 1. Jason __________ you as soon as he __________ home. A. will call; will arrive B. will call; arrived C. will call; arrives D. call; arrives 2.

从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.

初中英语语法专题（状语从句）讲解 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句：
Finish this so that you can start another.把这个做完，你可以开始另一个。 结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。 让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。 方式状语从句： Students do as the teachers say.学生们按照老师说的去做。 比较状语从句： The work isn't as easy as I thought.这项工作比我想象得难。 例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别： when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用 （=while）。如： When he came in, his mother was cooking. When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.

时间状语从句常由以下连接词引导：when（当……时），as（一边……一边；当…时），while（在……期间），after（在……之后），before（在……之前），as soon as（一……就），since（自从），till(until)（直到……，直到……才），whenever（任何时候），the moment（一……就），no sooner than（一……就），hardly…when… （一……就）等。由以上连接词（或词组）连接的主从复合句中，主句和从句的动作，有的是同时发生，有的是先后发生。因此，要特别注意根据连接词所代表的时间不同，主句和从句的谓语要使用相应的时态。这是掌握时间状语从句的关键。 1. when 和whenever 引导的从句：从句的动作和主句的动作可以同时发生，也可以先于主句的动作发生。例如： When we reached home, it was already dark. 我们到家的时候天已经黑了。 When my cousin came yesterday, I was playing volleyball. 昨天我表哥来时，我正在打排球。 When it rains, I go to school by bus.下雨的时候，我坐车去学校。 I shall tell her the good news when she comes. 她来时，我将告诉她这个好消息。（主从句都表示将来发生的动作，但要注意从句中要用一般现在时，表示将来。） Come to see us whenever you can.你什么时候有空，就过来看看我们。 2. while 和as 引导的从句：while表示“当…过程中”，强调某一段时间主句和从句的动作在同时发生。as表示“当…时”或 “一边…一边”，主句和从句的动作同时发生。例如： Work while you work; play while you play. 该工作的时候就工作，该玩的时候就玩。 While he is reading, he always makes notes. 他经常一面看书，一面做笔记。 She sings as she goes along.她边走边唱。 You will grow wiser as you grow older. 随着年龄的增长，你会更加聪明起来。 3. before 和after 引导的从句：前者一般表示主句的动作发生在从句动作之前。后者表示主句的动作发生在从句动作之后。 例如： I didn’t know any English before I came here. 我来这儿之前，一点英语都不懂。 I had written my report before my mother came back.
高考英语语法专题：状语从句解析及练习 状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、地点、比较、方式状语从句。 目录 时间状语从句 (1) 条件状语从句 (3) 让步状语从句 (3) 原因状语从句 (4) 目的状语从句 (5) 结果状语从句 (5) 地点状语从句 (6) 强化练习 (7) 时间状语从句 引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time等。时间状语从句中一般用一般现在时或一般过去时。
1．when , while, as都可解释为“当```的时候”但侧重点有所不同。 1) When后既可以接短暂性动词，也可以接延续性动词，表示从句动作与主句动作同时发生。 When I arrived home , I had a little rest. 2）As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着” He sang as he danced.(一面```一面) You will grow wiser as you grow older.(随着) 3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。 While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意：while 有对比的含义，解释为“然而”。eg: I prefer black tee, while he likes coffee. 2．until, not…until表示“直到`才”,在肯定句中主句常用延续性动词；在否定句中常用短暂性动词。 肯定句：I waited until midnight. 否定句：I did not leave until midnight. 注意点：1）not until…在句首，主句用倒装 Not until you had explained how did I manage to do it. 2) It is not until…that…引导的强调句It was not until it was dark that he came back. 3．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```” I had hardly/scarcely got home when it began to rain.
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?
