状语从句复习学教案➢考点揭密在复合句中修饰主句中的动词、形容词或副词，起状语作用的从句叫状语从句。
状语从句可置主语之前，也可置主语之后。
前置时，从句后用逗号与主句分开；后置时，与主句之间无标点符号。
状语从句可分为时间、原因、目的、结果、条件、比较、地点、让步、方式等九类。
中考考点设置1.时间状语从句(1)引导词：when,while,as,before,after, as soon as,until,since.(2)主句为将来时，从句用一般现在时代替。
(3)not...until的同义句替换。
*（4）when和while在过去将来时中的用法典型例题解析例1.---I hope you’ll enjoy your trip, dear!---Thank you, mum. I’ll give you a call _________ I get there.A. untilB. as soon asC. sinceD. till答案：B。
该题考查的是引导状语从句的从属连词的选择。
本题的意思是“一到那里，我就给你打电话。
”要表达这个意思应选用as soon as。
例2. None of us knew what had happened _________ they told us about it.A. whenB. untilC. afterD. though答案：B。
该题考查的是引导状语从句的从属连词选择。
本句的意思是“在……以前我们没人知道这件事。
”要表达着一意思应用“not…until” 这一句型。
例3.I’m sure. He will jump when he _________the good news.A. learn aboutB.will learn aboutC.learning aboutD.learns about答案：D。
时间状语从句中，逐句若是一般将来时，从句应用一般现在表示将来时的意思。
例4.The children _________a P.E. class on the playground when it suddenly began to rain.A.haveB. are havingC. hadD. were having答案：DWhen引导的从句时过去时态，说明在过去的时间里孩子们正在上体育课。
因此句子时进行时。

典型例题解析例1. You will stay healthy _______ you do more exercise, such as running and walking.A. ifB. howC. beforeD. where答案：A。
该题考查的是引导状语从句的从属连词的选择。
从意思上看，从句应是一个条件状语从句，在这四个选项中只有if能引导条件状语从句，所以选A。
例2. If I find his phone number, I _______you.A.tellB. toldC. will tellD. have told答案：C.本体考察的是If 引导的条件状语从句，如果我找到他的电话号码，我就告诉你，在条件状语从句中，主句用一般将来时，从句用一般现在时表示将来时的意思例3----May I go to the concert with you?----I’m afraid not ______you have a ticket,because I have only one.A.sinceB. ifC. unlessD. though答案C 由题意得知，我只有一张票如果你想和我一起去，除非你有一张票。
Since意为因为，If意为如果，unless 意为除非though 意为尽管，所以选C中考真题精选1. ---Jason wants to know if _________a school sports meeting tomorrow?----Yes, we will.

(3)because 不能与so 连用。
(4)because,since，as,for 的区别：because 从句所表示的是对方不知道的直接的原因，因此在回答以why引导的特殊疑问句时只可用because,而as,since 引导的从句却不可；as，since从句所表示的往往是对方已知的原因；for往往用于附加理由证明。
典型例题解析例1 He missed the train this moring________hre got up late.A. orB. ifC. butD. because答案：________此题考察状语从句连词，只要明白预警，分清选项中四个连词所表达的含义，就能正确选出答案，or 有“或者”和“否则”两个意思；if是“如果”的意思；but表示转折关系，意思是“但是”because表示因果关系，所以应选because中考真题精选1. .Because his mother was ill,_________he must stay at home to look after her.A./B.soC.thatD.either2. .—Why are you late for school?—_________ I got up late.A.BecauseB.ForC.SinceD.As3. He took off his coat _______ he felt hot. A. because B. as C. if D. since4.---Is everyone here today? ---No, Tom is at home_________he had a bad cold.A. bacause D. though C.if D. unless4.目的状语和结果状语(1)目的状语从句引导词：so that. in order that 从句中常用情态动词。
★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, mightwould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：Speak clearly so that they may understand you. (目的状语从句)Jack is badly ill so that he has to rest. (结果状语从句)(2)结果状语从句引导词：so...that,such...that.(3)so与such 的区别①so+形+a/an+名such+a/an+形+名②so+many/much/few/little+形+名如果名词前由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’t go to the cinema with you.③such+形+不可数名词/可数名词复数(4)so...that与too...to和...enough to间转换典型例题解析例1.---Sam, you look tired today,what’s the matter ?----I was _______busy _______I didn’t go to bed until midnight yesterday.A,too to B. so that C. so to D. such that答案_______ 此题答语意为“我太忙了以至于昨天知道半夜才睡觉”是一个结果状语从句。
