高三英语语法专题复习之状语从句
教材内容分析
本课是进行高三英语语法的复习，我在教学中将语法知识的传授和语言基本技能的学习结合到一起，注重复习语法与语言的运用。采用任务型教学法和小组合作探究学习法，从而扩大课堂的语言输入量及学生的语言输出量。
教学目标
1、知识与技能
引导学生准确把握非状语从句的使用。根据该语法规律解决实际问题。在运用语言的过程中培养学生的观察力、分析力、想象力和自学能力，帮助学生加强记忆力，提高思维能力和运用英语的综合能力，激发创造能力。
2、过程与方法
以学生为主体，尝试创新思维，联系社会采用讨论、协作、探究、竞争的教学模式，引导学生灵活运用所学语法知识
3、情感、态度的价值观。
用状语从句的句子结构表达思想感情和正确的世界观、人生观。形成健全的情感态度，为未来发展和终身学习奠定好的基础。
教学重难点
1）教学重点：了解和掌握状语从句的使用。
2）教学难点：能够运用此语法规则完成各种练习训练，并在实际语言活动中灵活运用。
一．状语从句的定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。状语从句通常由一个连词引起，也可以由一个起连词作用的词组引起，有时甚至不需要连词直接和主句连接起来。
状语从句一般分为九大类
时间状语从句地点状语从句原因状语从句目的状语从句结果状语从句
条件状语从句方式状语从句比较状语从句让步状语从句
二．状语从句的分类：
1．时间状语从句：
在时间状语从句中，要注意时态一致，一般情况下主句是将来时的时候，从句要用一般现在时。可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，又可分类如下：（1）表示同时性，即主从句的谓语动作同时发生或几乎同时发生。
其连词有：when （当……的时候）, while（当……的时候）, as（当……的时候）, once（一旦……）as soon as（一……就……）, the time（当……的时刻）, the moment（当……的时刻）, by the time（到……时候为止）, next time(下次), the first time(第一次……的时候), the last time(上次……的时候)，immediately（一……就……）, instantly（一……就……）,directly（一……就……）以下关联词引起的句子中，前面常用过去完成时，后面用一般过去时hardly /scarcely…when…（刚……就……）, no sooner…than…（刚……就……）
Strike while the iron is hot.趁热打铁。
While I am washing the floor, you can be cleaning the windows.（while含有对比的意思）
我洗地板的时候，你可以擦窗户。
As / When I came home, I met an old schoolmate of mine.我回家的时候遇到了我的一位老同学。I’ll ring you up as soon as I get an answer from him.我一有他的答复就给你打电话。
Once you see him, you will never forget him. 你一旦见过他，就不会忘了他的。
Hardly had we got into the country when it began to rain. 我们一到乡下就开始下雨了。
= We had hardly got into the country when it began to rain.
No sooner had he come home than she started complaining. 他一到家她就开始抱怨。
= He had no sooner come home than she started complaining.
He made for the door directly he heard the knock. 他一听到敲门声就向门口走去。
She rushed into the room immediately / the moment she heard the noise.她一听到声音就冲进房间He left me a good impression the first time I met him.我第一次见他时，他给我留下了好印象。He had no sooner arrived there than he fell ill.他刚到达那里就生起病来。
He had hardly finished when someone rose to refute his points.他还没说完就有人起来反驳他的论点
She had scarcely fallen asleep when a knock at the door awakened her.她刚要睡着，忽然敲门的声音把她惊醒。
★as、when、while用法一览表
类别
作用
例句
as
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。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......”
She came up as I was cooking.(同时)
The runners started as the gun went off.(几乎同时)
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。when
(at or during the time that )既可以表示在某一点的时候，又可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。如果表示从句的动作在主句的动作“之前”或“之后”发生时，多用when（=after）, 不用as或
while。此外，when还含有“at that moment”的意思（= and then），引起的句子不能放在句首，也不能用as, while来替换。
It was raining when we arrived.(指时间点)
When we were at school, we went to the library every day.(在一段时间内)
We were watching TV when suddenly the lights went out.我们正在看电视，这时灯突然灭了。They had just arrived home when it began to
rain.他们刚到家，这时天就开始下雨了。
while
while意思是“当……的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time 时，两者可以互换。
当主从句之间表示转折或对比关系时，多用while, 不用as或when
Please don’t talk so loud while others are working.
He fell asleep while/when reading. Strike while the iron is hot.(用as或when不可，这里的while 意思是“趁……”)
She thought I was talking about her daughter, while in fact, I was talking about my daughter.她以为我在谈论她女儿，而事实上，我在谈论我的女儿。
（2）表示先时或后时，即主句的谓语动作发生在从句之前或之后。
主要连词有：after（在……之后，before（在……之前）, when(=after)等。如：
After / When the children had gone to bed, she began to prepare her lessons.
孩子睡觉了以后她开始备课。（从句的动作发生在主句的动作之前，所以从句用了过去完成时）He had learned English for three years before he went to London. 他去伦敦之前已学了三年英语。
（主句的动作发生在从句的动作之前，所以主句用了过去完成时）
常用句型：It is/was/will be …before…要过多久才…
It will be another five days before we finish this task. 还要再过5天我们才能完成这个任务。
It isn’t/ wasn’t/won’t be …before…没有过多久就…
It was not long before I forgot it all. 我没有过多久就全忘了。
He ran off before I could stop him.（主句和从句的动作几乎同时发生，时态一致）
我还没来得及阻止他他就跑掉了。(注意before在汉语中的译义)
（3）表示习惯性、经常性，即从句描述的不是一次性动作，而是经常发生的习惯性动作。
主要连词有every time（每次）, each time（每次）, whenever（每当）等。
Whenever we met with difficulties, they came to help us.每当我们遇上困难的时候他们就来帮我们
Each time he came to town he would visit our school.他每次进城，总要来看看我们的学校。Every time I went to his house, he was out.我每次去他家，他都出去了。
(4）表示持续性或瞬间性
主要连词有：since（自从）,ever since（自从）,until（直到……才/为止,till（直到……才/为止）常用句型: It is /was…since…
It is just a week since we arrived here.我们到这儿刚刚一星期。
(主句的动作或状态持续时间较短，不能用ever since)
You have been reading to me ever since James went out. 自从James走后你一直在给我朗读。(ever 放在since之前是用来表示说话者强调主句动作或状态持续时间长)
The big clock which used to strike the hours day and night was damaged during the war and has been silent ever since.( ever since可以放在句末，since则不能)
这只一向日夜不停打点报时的大钟在战争中损坏了，从此就一直不响了。
My uncle went to Tibet in 1951. He has been living there ever since.我叔叔于1951年去了西藏，从那以后他一直生活在那里。
Things went well until / till one night an accident happened.事情一切正常直到一天晚上发生意外I knew nothing about it until / till he told me. 他告诉我了我才知道。
★until与till及not…until / till的用法
①until和till都可表示“直到．．．．．．为止”，与持续性动词的肯定式连用。如：
He waited until / till we finished our meal.他一直等到我们吃完饭。
②当until和till表示“直到．．．．．．才．．．．．．”时，通常与短暂动词的否定式连用，这时，until 和till也可用before代替。如：
I didn’t leave until / till / before she came back.直到她回来，我才离开的。
③be动词的肯定式和否定式都可以和until或till连用。
④until引导的从句可以放在主句之前或主句之后，但till从句一般不放在句首。如：
Until he told me, I knew nothing about it.他告诉我了我才知道。
当not until位于句首时，主句中的主语、谓语要使用倒装语序：
Not until she came back did I leave. = I didn’t leave until she came back.
在强调句型中一般用until，不用till。如：
It was not until she took off her dark glasses that I realized she was a famous film star.
2．地点状语从句
地点状语从句是由where（在……的地方）, wherever（无论哪里）引导的：
Wuhan lies where the Yangtze and the Han River meet.武汉位于长江和汉水汇合处。
Where there is a will, there is a way.有志者，事竟成。
You’d better make a mark where you have any questions.(这里where引导的从句不是定语从句) 哪儿有问题，你最好在哪儿做个记号。
He would keep in touch with us wherever he was.他无论在什么地方，总是与我们保持联系。3．原因状语从句
表示原因的状语从句可以由as（由于）,because(因为), since（既然）,now (that) (既然), for (由于)considering that（顾及到）, seeing that（由于）等连词引导：
I do it because I like it.因为我喜欢我才干。(because不能与so连用)
He couldn’t have seen me, because I was not there.他不可能见过我，因为当时我不在那儿。Seeing (that) quite a few people were absent, we decided to put the meeting off.由于好些人都没到会，我们决定延期开会
Now that/Since you are all here, let’s try and reach a decision.既然大家都来了咱们就设法做一个决定吧
As she was ill, she didn’t come to the party.由于病了，她没来参加晚会。
Considering that they are just beginners, they are doing quite a good job.考虑到他们才刚刚学做，他们干得算很不错的了。
★because, as, for , since 的区别
类别
用法
例句
because
because语气最强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 从句是全句最重要的部分，通常它被置于主句之后。下列情况下只能使用because:
①在回答why的问句时；②在用于强调句型时；
③被not所否定时。
You want to know why I’m leaving? I’m leaving because I’m full.
for
for的语气不及because, since, as强，为并列连词，引导的分句常放在主句之后，从句前通常用逗号，表示说话者为所做的推断和预测提供理由，或对前一分句进行补充和解释。如果不是因果关系，而是对前面主句的内容加以解释或推断时，只能用for。
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。）as/since
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，但有时却相反。
Seeing all of the children already seated, he said,“Since everyone is here, let’s start.”
4．目的状语从句
引导目的状语从句的主要连词有: so that（以便）, in order that（为了）, for fear that（以便）,目的状语从句的谓语动词常与情态动词can, could, may, might, should连用
Let’s take the front seats (so) that we may see more clearly.我们坐前排吧，这样我们看得更清楚些。
School was closed early in order that the children might go home ahead of the storm.
早点儿放学是为了让孩子们在暴风雨到来之前回家。
He took the name down for fear that he should forget it.
他把名字写下省得忘了。（该从句中一般用情态动词should+动词原形，或省略should）Better take more clothes in case the weather is cold.最好多带些衣服以防天气会冷。
5．结果状语从句
引导结果状语从句的连词有：that, so that（从句中不带情态动词）, so…that(如此……以致……), such…that(如此……以致……)等。
What has happened that you all look so excited? 发生了什么事，使你们都显得如此兴奋？
He didn’t plan his time well, so that/so he didn’t finish the work in time.
他没把时间计划好，结果没按时完成这项工作。
We left in such a hurry that we forgot to lock the door. 我们走得匆忙，把门都忘了锁了。
The village is so small that it cannot be shown in the map.这村子太小，所以这地图上没有。Jenny is such a clever girl that all the teachers like her very much
= Jenny is so clever a girl that all the teachers like her very much
Jenny是如此聪明的女孩，以至老师们都非常喜欢她。
注意：so + 形容词/副词+ that从句；such +名词+ that从句。
但是，当名词前有many, much, few, little(少)修饰时，要用so,不能用such。
I have had so many falls that I am black and blue all over.我摔了许多跤，以至于浑身青一块紫一块
He has so few friends that he often feels lonely.他朋友很少，所以经常感到孤独。
I had so little money then that I couldn’t afford a little present.我当时囊中羞涩连一份小小礼物都买不起
6．条件状语从句
表示条件的状语从句可以由if（如果）,unless（除非）, in case（万一）, so /as long as（只要）,
as/ so far as（就……而言）, on condition that（条件是……）suppose（假设）supposing（假设）（仅用在问句中）等词或词组引导。一般情况下当主句是将来时的时候，从句要用一般现在时。
As/So long as we don’t lose heart, we’ll find a way to overcome the difficulty.
只要我们不灰心，我们就能找到克服困难的方法。
Send us a message in case you have any difficulty.万一你有什么困难，请给我们一个信儿。
If you leave at 6 o’clock tomorrow morning, you’d better get to bed now.
如果你明早6点钟走，你最好现在就上床。
We’ll let you use the room on condition that you keep it clean and tidy.
只要你能保持整洁，我们可以让你使用这个房间。
As/So far as I know, he is an expert on DNA.据我所知，他是一个DNA专家。
He’ll accept the job unless the salary is too low/ if the salary is not too low.
他会接受这项工作的，除非薪水太少/如果薪水不太少的话。
Suppose/Supposing we can’t get enough food, what shall we do?
假设我们弄不到足够的食物，那我们怎么办？
7．方式状语从句
方式状语从句常由as（与……一样）, as if（仿佛）, as though（仿佛）等词引导：
Do in Rome as the Romans do.入乡随俗。
Leave things as they are.让一切顺其自然。
She stood at the door as if (=as though) she were waiting for someone.她站在门口，仿佛在等人似的。（由as if或as though引导的从句中可用虚拟语气）

Our country is as big as the whole of Europe.我们的国家同整个欧洲一样大。
The result was not as/so good as I had expected.结果不如我预料的那么好。
常见句型：the +比较级，the +比较级

9．让步状语从句
让步状语从句由although（尽管）, though（尽管）, however（无论怎样）,whatever（无论什么）, whoever（无论谁）, whomever（无论谁）, whichever（无论哪个）,whenever（无论何时）, wherever（无论哪里）, whether（是否）, no matter (who, what, where, when) （无论……）, even if（即使）, even though（即使）等词引导。

No matter what I say or how I say it, he always thinks I’m wrong.无论我说什么或怎么说，他总认为是我错。
连词as也可以引导让步状语从句，但从句中要用特殊语序。如：
Young as he is, he knows a lot=Though he is young 或Young though he is, he….
他虽然年轻，但懂得很多。(though 也有这种用法，可以替换as,但although没有这种用法) though还可以用作副词，放在句末。如：
It was hard work;; I enjoyed it, though=It was hard work, but I enjoyed it.那工作很苦但是我喜欢
干
一般情况下，unless相当于if…not，可以互换。如：
I won’t let you in unless you show me your pass = I won’t let you in if you don’t show me your pass.如果你不出示通行证，我就不让你进来。
10．省略现象
有些表示时间、地点、条件、方式或让步等的状语从句中，如果谓语含有动词be，主语又和主句中的主语一致，或者主语是it，常把从句中的主语和谓语的一部分（特别是动词be）省略掉。注意状语从句中从句的省略现象
（1）连接词+ 过去分词

教学反思：
能够引导学生准确把握状语从句的使用。根据该语法规律解决实际问题。在运用语言的过程中培养学生的观察力、分析力、想象力和自学能力，帮助学生加强记忆力，提高思维能力和运用英语的综合能力，激发创造能力。
-老师把学生分成小组进行回顾，讨论，归纳，总结出状语从句的定义，类型及各类型状语从句的引导词，使用语境，然后给予适当的补充，给他们实例和练习进行巩固。当然，语法学习不能只停留在纯粹的语法规则的记忆上，而更要注重学生对这一语法知识的运用上。
所以，课后老师还应给学生相应的文本让学生在阅读文本的过程进一步感知这一语法点并指导学生在写作中灵活运用这一语法点，真正提高语用能力。

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：

On the chair sat a young woman with a baby in her arms. The baby was thin. 4、用在世界上独一无二的事物前。如： the earth, the moon, the sun. 5、用在序数词和形容词最高级前。（副词最高级前的定冠词可省略）如： He is always the first to come to school. Bob is the tallest in his class. 6、用在某些专有名词前（由普通名词构成的专用名词）。如： the Great Wall, the Summer Palace, the Science Museum, the Children’s Palace, the Party等。 7、用在一些习惯用语中。如： on the day, in the morning (afternoon, evening), the day after tomorrow, the day before yesterday, the next year, by the way等。 8、用在江河湖海、山脉前。如： the Yellow River, the Pacific Ocean, the Alps, the Himalayas 9、用在报刊、杂志前。如： the People’s Daily, the Evening Paper, the Times 泰晤士报。 10、表示某一家人要加定冠词。如： The Browns are at home to receive visitors today. 布朗一家今天要接待客人。 11、用在形容词前，表某一类人。如： the poor, the wounded, the living, the dead, the rich, the sick等。 12、定冠词可以表示一事物内部的某处。如： The driver always sits in the front of the bus(car). 三、零冠词（即不用冠词）： 1、专用名词和不可数名词前。如： China, America, Grade One, Class Two, milk, oil, water, paper, science等。 2、名词前已有作定语用的this, that, my, your, some, any等代词。如： Go down this street. 3、复数名词表示一类人或事物时。如： We are students.

语法填空公开课
语法填空专题教案 一、教学目标： 1.让学生了解语法填空题考察内容； 2.让学生掌握语法填空题解题技巧； 3.让学生注意平常对词汇的积累，大量阅读课外材料，培养词感和语感，加强基本功；并注意生活常识的积累。 二、教学重点： 总结语法填空题的解题技巧 三、教学难点： 学生掌握语法填空题的解题技巧 四、教学过程 Step1:Lead-in(导入) Step2:语法填空题考察内容和解题思路 1.考察内容： a.语境(上下文）； b.语法：动词（时态、语态、主谓一致、非谓语形式）、名词、代词、冠 词、介词、连词固定搭配、情态动词、复合句、形容词和副词的比较 级最高级及构词法、倒装等。 2.解题思路： a. 纯空格填空：一般考察介词，连词，代词，冠词，从句引导词，情态动词，强调助动词等 b.给出提示词填空：谓语动词和非谓语动词（前者要考虑时态和语态以及主谓一致；后者主要是to do,doing,done及变形） c.词类转换题（名词，形容词，副词，形容词或副词的比较级或最高级，词义的否定） Step3:案例分析讲解与练习 解题高招 1. 通读全文，把握大意。 2. 结合语境，试填空格。
具体来说，可按设题类型分为三类情况： (1)纯空格试题的解题技巧。 技巧1：缺主语或宾语，一定是填代词或名词(多考代词)。如： [例1] when I told my parents my story, ____ didn’t think it was a mistake.技巧2：名词前面，若没有限定词(冠词，形容词性物主代词，名词所有格，基数词，序数词，不定代词)，很可能是填限定词。如： [例2]The young man went home with a happy heart. After the student left, the teacher let _______ student taste the water. 技巧3：句子不缺主语、表语、动词后不缺宾语的情况下，名词或代词前面，一定是填介词。 [例3]My parents took good care ___ me. 技巧4：若两个或几个单词或短语之间没有连词，可能是填连词。 [例4]…two world-famous artists, Pablo Picasso ___34___ Candido Portinari, which are worth millions of dollars. 技巧5：若结构较完整，空格后的谓语动词是原形，特别是与上下文时态不一致或主谓不一致时，很可能是填情态动词或表示强调或倒装的助动词(do, does, did等)。 [例5] He had no time or energy to play with his children or talk with his wife, but he ______ bring home a regular salary. 技巧6：定语从句缺主语或宾语，一定是填适当的关系词，如：who, that, which, whom。 [例6]He would open the box, take out an imaginary kiss, and remember the love of this beautiful child _______ had put it there. 技巧7：由特殊的句式结构或固定搭配来判断空格应填的词。 [例7]_____ was only after I heard she became sick that I learned she couldn’t eat MSG(味精). (2) 给出提示词填空的解题技巧 首先，判断要填的动词是谓语动词还是非谓语动词。然后按以下两点进行思考。技巧8：若句中没有别的谓语动词，或者虽然已有谓语动词，但需填的动词与之
