状语从句教案
状语从句（2h）
教学目标：掌握9大状语从句及其中重要的引导词与句型。由于高考中状语从句经常和从句的时态语态，动词短语的搭配，以及状语从句的省略，虚拟语气与倒装一起考查。因此必须掌握好：
1 时间状语从句中各种引导词引导的主句与从句的时态的判断
2 地点状语从句中表示抽象含义时从句必须在主句之前
3 原因状语从句中because，as，now that的位置问题
4 目的状语从句中的so that与在结果状语从句中的区分
5 结果状语从句中的so/such…that…的特殊结构及其倒装
6 条件状语从句中的if，unless的用法
7 方式状语从句中的虚拟语气的用法
8 让步状语从句中的as, though做引导词时的倒装用法
教学重点：1 掌握常用的状语从句中的引导词
2 判断状语从句中的时态
3 状语从句中的倒装情况：no sooner…than, hardly/scarcely…when, not…until用于句首时的倒装；结果状语从句中so/such置于句首时的倒装情况；as/though引导的让步状语从句的倒装情况
4 as if/though引导的方式状语从句中的虚拟语气
教学进程：
导入：状语从句在句子中作状语，修饰谓语。
㈠时间状语从句
⒈回顾有哪些词可以引导时间状语从句—when, while, as表示“当…时”; immediately, instantly, as soon as, directly, the moment, no sooner than, hardly when, scarcely when, once表示“一…就…”；till, until, not until表示“直到…才”；before 表示“还没来得及…就…”，“不到…就…”；since表示“自从…”；every time, each time, next time, the first time, any time, all the time表示“每当…”，“每次…”，“下次…”等等
⒉状语从句中的时态的判断方法：
⑴过去，现在，将来
⑵延续性与非延续性/时间点与时间段
⑶主从句中的谓语动词的先后关系
⑷判断开始时间与截止时间
⒊when, while, as都可以表示主从句动作同时进行(口头造句举例)
如：when the music fades away, people tide away.
She sat there alone while others were all dancing.
He dances joyfully as the music goes.
当主句动词为短暂性，从句动词用延续性动词的进行时态表示一段时间内的动作时，三个词可互换。如上面的第二个句子。
When可引导持续动作亦可引导短暂动作。如
When I was young, I used to play Barbie dolls.
While引导的必须为延续性动词，侧重和主句中的动词相对比。如
While he was making the breakfast, his wife was sleeping.
As可以指主从句的动作交替进行。如
She feels someone’s following her, so she walked fast as lotoked back.
⒋“一…就…”
⑴The moment she heard the music she liked most, she stood up to dance.
⑵Hardly had the Cinderella got home when the clock knocked 12 o’clock.
⑶As soon as I get there, I’ll let you know.
(强调当no sooner than和hardly when, scarcely when提到句首时要用到倒装)⒌till, until, not…until
⑴肯定句：主谓语必须为延续性动词
You can dance to your joy until you feel tired.
⑵否定句：主从句必须为非延续性动词
You can’t marry him until I say yes.
（强调till不能放句首，until可以）
6. before
⑴I hadn’t finished my sentence before he turned his back to me。
⑵It will be 2 years before I get back.
7. since
I haven’t spoken to him since 1 year ago.
It is 3 years since I smoked.
It has been 3 years since I smoked.
8．Every time…
歌词：every time I leave to head out on the road, I wanna take you with me, save me from the cold.
练习：
1 We usually call someone a green hand ____(当他没有经验)his job.(experienced)
2 I was speaking to Ann on the phone___（突然我们短线了)(cut)
㈡地点状语从句
表示抽象含义时，从句需在主句前。如
Where there are girls, there is gossip.
where引导的定语从句与状语从句
You’d better make a mark where you have any questions.（状从）
You’d better make a mark at the place where you have any questions. (定从)
㈢原因状语从句
回顾有哪些引导词—because, since, as, now that, seeing that, considering that, owing to, because of, thanks to, due to, for
When有时也表示原因。如
It is silly of you to take his words when every one tells you he’s a liar.
㈣目的状语从句
So that, in order that, for fear that, in case,lest等
She looked at the clock now and then, for fear that she might get home late.
He has made up a whole story in case she asks.
㈤结果状语从句
So+形容词/副词+that从句
So+形容词+a/an+可数名词单数+that从句
So+many/much/few/little+名词+that从句
It is so easy that even a five-year-old student can work it out.
Such+a/an+形容词+可数名词单数+that从句
Such+形容词+可数名词复数/不可数名词+that从句
Such+a lot of/lots of+名词+that从句
He is such a strange girl that no one like to talk to her.
So或such置于句首倒装
So poor a girl she is that she has no freedom at all.
Too…to与not enough…to与so…as to…
㈥条件状语从句
As/so long as, if, unless, in case(与目的状语从句中意义不同), supposing, provided that
In case—
In case there is a fire, what will us do first?
She always dress herself well in case he come to see her.
㈦方式状语从句
As, as if, as though
As if/though引导的从句如果很难实现或与事实相反，应用虚拟语气。如Don’t look at me like that as if I had done something wrong.
㈧让步状语从句
Although, though, 可与yet, still或nevertheless连用，不能和but连用。
Even though, even if有时需要用虚拟语气。如
Even if I were busy, I would go.
Though有时可以用于句末，指“然而“
He said he would come, he didn’t, though.
As与though引导的从句用于主句之前时应使用虚拟语气。表语是单数名词时，前置时还应省略冠词
Child as my son, he knows a lot.
Much as I like it, I won’t buy it.
Whether…or…,wh+ever, no matter wh+ever
Whether you believe it or not, it’s true.

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。
高中英语必修二状语从句教案
一地点状语从句 地点状语从句通常由where, wherever 引导。 Where I live there are plenty of trees.我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 二. 方式状语从句 方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：Always do to the others as you would be done by.你希望人家怎样待你，你就要怎样待人。As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： They pletely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。） He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He stared at me as if seeing me for first time.他目不转睛地看着我，就像第一次看见我似的。He cleared his throat as if to say something.他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger.波涛冲击着岩石，好像很愤怒。 三. 原因状语从句 比较：because, since, as和for 1）because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或since。 I didn't go, because I was afraid. Since /As the weather is so bad, we have to delay our journey. 2）由because引导的从句如果放在句末，且前面有逗，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。 He is absent today, because / for he is ill. He must be ill, for he is absent today. 四. 目的状语从句 表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导，例如：

初中英语If引导的条件状语从句演示教学
初中英语――if引导的条件状语从句 在if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则.引导条件状语从句的连接词主要有：if(如果）、unless（除非）或as long as （只要）等。unless在意思上等于if...not。 一、条件状语从句用法 1、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： 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。 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。 2、unless = if...not.除非,若不,除非在……的时候 例如：Let's go out for a walk unless you are too tired. =If you are not too tired, let's go out for a walk. Unless it rains, the game will be played. 除非下雨,比赛将照常进行。 二、时态问题 在条件状语从句中，要注意“主将从现”的规定，即主句用一般将来时，从句用一般现在时表示将来时。例句： I will come to see you if I have time. 我有时间，我就来看你。 三如果if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如： If bears are in danger ,they attack people. 误区提醒 if 既可以引导条件状语从句，表示“如果”，也可以引导宾语从句，表达“是否”。辨别它在这两种从句中的时态是我们经常容易出错的地方。另外，if 和unless的用法也需注意。 典型例题：----I wonder if your wife to the party. ----If your wife _________, so will mine。. A. will go，go B. will go, goes C.goes, will go D. will go, will go 解析：第一句中if表示“是否”，引导宾语从句，用将来时will go；第二句“如果你的妻子去，我的妻子也去”，if引导条件状语从句，用一般现在时表示将来时。your wife，单三人称主语，所以用goes 。

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。
