初中英语状语从句讲解、练习与答案(教案)
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 ops.
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 help you 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 late. =If you 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：
He didn ' t come to school becaus e was ill.
As it is raining, we shall not （不得；不应该）go the zoo.
Since you can ' t an swer the questi on, I ' ll ask some one else.
⑵because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 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：
----- Why ar en' t going there?
----- Because I don ' t want to.
As he has no car, he can ' t get there easily.
Since we have no money, we can ' t buy it.
⑶because和so不能同用在一个句子里。
4. 结果状语从句
⑴结果状语从句由so…that, such …that, so引导。例如：
He is so poor that he can ' t buy asasonf（和too...to...句型的转换复习）
She is such a good teacher that everybody likes her.
My pencil fell under the desk, so that I couldn ' t see it.
⑵so…that语such...that可以互换。例如：
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.
The hall is so big that it can hold 2,000 people.
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；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。例如：It was such a hot day that n obody wan ted to do anything.
He had such long arms that he could almost touch the ceili ng.（天花板）
He made such rapid progress that he did very well in the mid-term.
有时上述两种结构是可以互换的。例如：
It was such a won derful film that all of us wan ted to see it aga in.
=The film was so won derful that all of us wan ted to see it aga in.
It is such an importa nt match that no body wants to miss it.
=The match is so importa nt that n obody wants to miss it.
⑶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 go to the cinema （去看电影）with you.
5. 比较状语从句
比较状语从句通常由as…as,比较级+ than ??等连词引导。例如：
Tom runs faster tha n Joh n does.
This classroom is as big as that on e（is）.
6. 目的状语从句
We started early so that we could catch the first train.（动词不定式作目的状语的转换练习）
He studies hard so that he could work better in the future.（和不定式短语so as to 的转换练习）
We used the computer in order that we might save time.（和不定式短语in order that 的转换练习）
（2）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:
I 'llspeak slowly so that every one of you can understand well .（目的状语从句）
Jack is badly ill so that he has to rest. （结果状语从句）
He ran quickly so that he won the race . （结果状语从句）
He ran quickly so that he could win the race , （目的状语从句）
7. 让步状语从句
（1）让步状语从句通常由although, though等连词引导。例如：
Though he is young, he knows a lot.
Although I am tired, I must go on working.（复习go on doing,go on to do）
⑵although（though）不能用在同一个句子中。例如：我们不能说：Though it was raining hard, but he still went out. 应该说：Though it was raining hard, he still went out. 或It was raining hard, but he still went out.
⑶even if/even though表示"即使。。。，纵使。。。。"之意，含有一种假设
We'll make a trip even if / eve n though the weather is bad .
⑷no matter +疑问词 "不论。。。都。。。"
No matter what happe ned , he would not mind = Whatever happe ned , he would not mind .,
No matter who you are , you must keep the law.= Whoever you are , you must keep the law .
8. 地点状语从句
地点状语从句常常由where来引导。例如：
Go where you like.
Where there is a will, there is a way.
9. 方式状语从句
方式状语从句常用as,as if,as though引导
He speaks En glish as the En glishme n do .
He talks as if he knew all about it .
She loves the boy as though he were her own son .
⑴目的状语从句通常由so that, in order that （为了，以便）引导。例如:
总结：状语从句分类及常用连词：
类别连词
时间状语从句whe n, whe never, while, as, before, after, since, till, once （—旦）地点状语从句where, wherever
原因状语从句because, si nee, as, for, now that （既然，由于）etc.
目的状语从句in order that（为了，以便）,so that, that, etc.
结果状语从句so …that, so that, such …that, that, etc.
条件状语从句if, uni ess, as（so）l ong as, etc.

初中英语时间状语从句讲解及练习
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。

初中英语状语从句及练习题(含答案)合集
状语从句的分类 一、时间状语从句 时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since等。 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同引导词所表示的不同时间关系， 以及它在具体句子中对应的时态、语态等问题。 注意：as（在……时候，因为），since（自从，因为），它们可以引导时间从句，并强调主句 和从句的动作同事发生。并且while有时还可以表示对比。例如： （1）While my mother was reading the newspaper, I was watching TV.(read是延续性的动词，read和watch同事发生) I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比） （2）when（当……的时候），引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。 从句动作可与主语动作同事发生，也可在其后发生。 I was reading a book when she came into my room.(come是瞬间动词，只能用when引导，不 能用while) I often missed my home when(while) I lived in NewYork.（live是延续性动词，when可用while代替） （3）when和while的区别还在于：while引导的时间状语从句多用于进行时态，而when引导的 时间状语从句多用于一般时态。 While they were talking, the bell rang.正在他们谈话的时候，上课铃响了。 （4）as译作“一边……一边”、“随着……”，侧重主句和从句的动作同时发生。有时可与when，while通用。 We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”） As you grow, you will know more and more。随着年龄的增长，你会懂得越来越多。 2.till或until引导的时间状语从句 till，until（直到……才）：一般情况下两者可以互换，但是在强调句型中多用until。till 不可以在句首，而until可以放在句首。 注意：如果主句中的的谓语动词是瞬间动词时，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： I didn’t go to bed until(till) my father came back.直到我父亲回来我才上床睡觉。（go to bed 是瞬间动词，主句用否定形式） I talked until he came back.我工作到他回来为止 I didn't work until he came back.他回来我这才开始工作 Please wait until I arrived.在我到达之前等我。 3.since引导的时间状语从句
初中英语——条件状语从句
初中英语―条件状语从句 一．条件状语从句的概念 条件状语从句，即在某种条件下，一件事情可能发生。在英语中由连接词if或unless 等引导的状语从句叫做条件状语从句。条件是指某一件事情实现之后（状语从句中），一件事情（主句）才能发生，通常译作“假如，只要，如果”等意思。条件状语从句中，主从句的时态要遵循“主将从现”的原则。即，主句是将来时态时，从句用一般现在时代替将来时态。 二.条件状语从句的引导词 1.If conj . 如果，假如 If you ask him，he will help you．如果你请他帮忙，他会帮你的。 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。 2.unless conj.除非,若不,除非在……的时候（if ...not...） 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。 3.so/as long as conj.只要 You may borrow my book as long as you keep it clean. 只要你保持书的清洁，你就可以把我的书借去。 三．关于条件句的时态，常见的有以下三种情况： 1、条件状语从句的主句是一般将来时，那么从句常常用一般现在时。 When I grow up, I’ll be a nurse and look after patients. 我长大后要当一名护士，照顾病人。 2、如果主句是祈使句，那么从句通常要用一般现在时。 If you want to have a chat ,call me up. 如果你想聊天，打我电话。 3、如果主句是含有情态动词时，根据需要从句多用一般现在时。
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：
初中英语状语从句知识点总结
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 ｇeｔｔｈere．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 Englisｈweｌl unｌess you woｒk 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。
