状语从句要点复习


状语从句不仅是初中英语学习的重点,而且也是每年中考必考的内容之一。从笔者研读历年全国各地中考英语试题对状语从句的考查内容来看,命题主要集中在引导状语从句的连词、状语从句的时态等方面;从九大状语从句(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、让步状语从句、比较状语从句、方式状语从句)来看,同学们应将复习重点放在时间状语从句、条件状语从句、结果状语从句和比较状语从句这四种上。


 一、对时间状语从句的考查


1.要点:


1)引导时间状语从句的连词有:while whenasas soon asuntilnot...untilbefore aftersinceetc.要掌握每个连词的含义及其用法,还有它们之间的一些区别。


2whenwhileas的区别:


三者均可表示……的时候,如果主句表示的是短暂的动作,而从句表示的是一段时间,三者可通用。如:


I met Kang Li aswhenwhile I was walking along the street.当我沿街散步时碰见了康丽。


②aswhen都可与终止性动词连用, while只能与延续性动词连用。如:


It was snowing when we got to the airport.当我们到达机场时,天正下着雪。(不能用 while


③as强调主句与从句表示的动作同时发生;while强调主句表示的动作持续于while所指的整个时间内;when可指主、从句所述动作同时或先后发生。如:


He sang as he went along.他边走边唱。


Please write while I read.我读的时候,请写下来。


When he reached homehe had a little rest.回到家后,他休息了一会儿。


 3untiltill在肯定句中表示直到……为止,主句要用延续性动词;在否定句中,表示直到……,主句常用终止性动词,这时tilluntil可用before替换。如:


I waited tilluntil he arrived.我一直等到他到来。


We won't start untiltillbefore Bob comes.鲍勃到来之前,我们不会动身。


4since从句中常用过去时,主句用一般现在时或现在完成时;如果主句是一般将来时,情态动词加动词原形或祈使句时,时间状语从句用一般现在时。如:


Where have you been since I saw you last?上次我和你见面之后,你到哪里去了?


I'll phone you as soon as I arrive in Tonghua.我一到通化就给你打电话。


2.考例:(所有考例取自20012002年全国各省市中考英语试题)


1)我一到美国就给你打电话。(北京市海淀区)


   I'll ring you up ______ soon ______  I get to America


2)昨天直到雨停了,孩子们才离开学校。(同上)


   The children ______  leave school ______  the rain stopped yesterday


3It ______  ten years since they ______  to France.(河北)


    Aascovered


    Bwashave moved


    Cishave moved


    Dismoved


 4He ______  wait until the rain ______ .(南京市)


     Awon'twill stop           Bwon'tstop


     Cwillstops               Dwillwill stop


 Key:一、21asas 2didn'tuntiltillbefore 3D 4C


二、对条件状语从句的考查


1.要点:引导条件状语从句的连词有if(如果)、unless(除非)等,unless在意义上相当于if...not。条件状语从句也像时间状语从句一样,如果主句用将来时,从句要用现在时代替将来时。如:


You will fail unless you study hard.(=You will fail if you don't study hard.)除非你努力学习,否则你会失败。


2.考例:


1He will go to the Great Wall if it ______  tomorrow.(北京市宣武区)


   Awon't rain


   Bdoesn't rain


   Cdon't rain


   Disn't raining


2 ______ you eat old foodyou may be ill.(湖南)


   ABefore


   BWhy


   CIf


   DWhich


三、对比较状语从句的考查


1.要点:引导比较状语从句的连词有as...asthan


1)表示甲与乙在某一方面相同时,用“as+原级+as”句型;表示甲在某一方面不如乙时,用“not as so +原级+as”句型。如:


Dalian is as beautiful as Shenzhen.大连和深圳一样的美。


 I don't run asso fast as Kang Li.我不如康丽跑得快。


2)表示甲超过或不及乙时,用比较级+从句(从句中常省略意义与主句相同的部分)。如:


He runs faster than youdo).他跑得比你快。


Today is less cold than yesterday.今天没有昨天冷。


2.考例:


1Jack runs as ______  as Tom.(北京市宣武区)


   Afast


   Bfaster


   Cfastest


   Dmuch faster


230000dollars is a large amount of moneybut it's ______  than we need.(上海市)


   Afor more


   Bvery much  


   Cfar less


   Dvery little


四、对结果状语从句的考查


  1.要点:引导结果状语从句的连词有so...that(如此……以致于),such...that(如此……以致于)等。常用句型:


so+形容词/副词+that从句


such aan +形容词+单数可数名词+ that从句


such+形容词+复数可数名词/不可数名词+that从句


so+形容词+aan+单数可数名词+that从句


He spoke so fast that I couldn't follow him.他讲得太快,我跟不上。


 He told us such funny stories that we all laughed


 他给我们讲了那么多有趣的故事,我们全都哈哈大笑。


  2.考例:


  1)这山太高,我们很难到达山顶。(四川)


     This mountain is ______  ______  that we can ______  ______  the top


  2Miss Gao asked a questionbut it was ______ that nobody could answer it


  Avery difficult   Btoo difficult  Cdifficult enough  Dso difficult


五、对其它状语从句的考查


还有五种状语从句:地点状语从句、原因状语从句、目的状语从句、方式状语从句、让步状语从句。


  1.要点:


  1)掌握常用的引导词:


   引导地点状语从句的有:where(在哪里),wherever(无论何地),etc.如:


  Where there is a willthere is a way.有志者,事竞成。


  Wherever you goI go too.无论你去哪里,我都去。


②引导原因状语从句的有becauseas since(因为),etcbecause常回答why引导的疑问句,该从句一般位于主句后;sinceas正式,两者不回答why引导的问句,而且其从句一般放在句首。如:


 Why can't I go?为什么我不能去?


 Because you're too young.因为你年纪太小了。


AsSinceyou are not feeling wellyou'd better stay at home


 既然你不太舒服,还是留在家里的好。


③引导目的状语从句的有so that(以便)等。如:


I packed him a little food so that he wouldn't be hungry


 我给他包了一点食物,让他不致挨饿。


④引导方式状语从句的有as(按照)等。如:


  I will do it as you tell me.我将照你说的做。


 ⑤引导让步状语从句的有thoughalthough(虽然),even though(尽管),whoever no matter who(无论谁),howeverno matter how(无论怎样),whateverno matter what(无论什么)等。如:


Though it's hard workI enjoy it.尽管这工作很辛苦,我还是很喜欢。


No matter how hard the work washe never gave it up.不管工作多么艰难,他都从不放弃。


 2because不能与并列连词sothough although不能与but同时在句中使用。如:


     She was late for school because she missed the bus


   


        She missed the busso she was late for school


      It's not cheapbut it's very good


   


        Though it's not cheapit's very good


2.考例:


 1I can't understand this passage _____ there are no new words in it.(安徽)


     Aif       Bbecause  Cthough  Dand


 2)“Why did Li Lei use a pencil?”“ _____ his pen was broken.”(福州市)


     ABecause    BWhen    CUntil   DIf


六、对状语从句和宾语从句、简单句、并列句的混合考查


 【考点1】区分whenif引导宾语从句和状语从句的不同:when引导时间状语从句意为“当……时候”,引导宾语从句意为“什么时候”;if引导条件状语从句意为“如果”,引导宾语从句意为“是否”。如:


  1.—Mike wants to know if _____  a picnic tomorrow


    YesBut if it _____  we'll visit the museum instead.(河北)


     Ayou havewill rain


     Byou will havewill rain


    Cyou will haverains

    SorryI don'tWhen he _____  back I'll tell you.(安徽)


    Acomescomes


    Bcomeswill come


     Cwill comecomes


   Dwill comewill come


 【考点2】状语从句和宾语从句、状语从句和简单句、并列句的同义转换。如:


 1AHe is too young to go to school


    BHe is _____ young _____  he can't go to school.(四川)


  2ATom is the tallest in his class


     BTom is _____  _____  any other student in his class.(四川)
