1、Charles,Apr,26th/2010,中考英语语法专项复习连词及状语从句,状语从句的复习重点及考点透视状语从句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;从九大状语从句来看,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,when,as,as soon as,until,notuntil,before,after,since,etc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。,2)when,while,as的区别:三者均可表示“当的时候”,如果主句表示的是短暂
2、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。as和when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(不能用 while)as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 wh
3、ile I read我读的时候,请写下来。When he reached home,he had a little rest,3)until和till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“直到才”,主句常用终止性动词,这时till和until可用before替换。如:I waited tilluntil he arrived我一直等到他到来。We wont start untiltillbefore Bob comes鲍勃到来之前,我们不会动身。4)since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
4、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?Ill phone you as soon as I arrive in Tonghua我一到通化就给你打电话。,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)Ill 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 3)It _ ten years sin
5、ce they _ to France.(河北)Aas;covered Bwas;have moved Cis;have moved Dis;moved 4)He _ wait until the rain _(南京市)Awont;will stop Bwont;stop Cwill;stops Dwill;will stop,as,as,didnt,until/before,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ifnot。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:Yo
6、u will fail unless you study hard(You will fail if you dont study hard)除非你努力学习,否则你会失败。2考例:1)He will go to the Great Wall if it _ tomorrow(北京市宣武区)Awont rain Bdoesnt rain Cdont rain Disnt raining 2)_you eat old food,you 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asas,than。1)表示甲
7、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.I dont run asso fast as Li2)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 you(do)他跑得比你快。Today is less cold than yesterday今天没有昨天冷。1)Jack runs as _ as Tom(北京市宣武区)Afast Bfaster Cfastest Dmuch fast
8、er 2)30,000dollars is a large amount of money,but its _ 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sothat(如此以致于),suchthat(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 couldnt
9、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 2)Miss Gao asked a question,but it was _that nobody could answer it Avery difficult Btoo difficult Cdifficult enough Dso difficult,so h
10、igh,not reach,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 will,there is a way有志者,事竞成。Wherever you go,I go too无论你去哪里,我都去。引导原因状语从句的有because,as,since(因为),etc。because常回答why引导的疑问句,该从句一般位于主句后;since比as正式,两者不回答why引导的问句,而且
11、其从句一般放在句首。如:Why cant I go?Because youre too youngAs(Since)you are not feeling well,youd better stay at home 既然你不太舒服,还是留在家里的好。,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 wouldnt be hungry 我给他包了一点食物,让他不致挨饿。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。引导让步状语从句的有thoughaltho
12、ugh(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 its hard work,I enjoy it尽管这工作很辛苦,我还是很喜欢。No matter how hard the work was,he never gave it up不管工作多么艰难,他都从不放弃。,2)because不能与并列连词so,though although不能与but同时在句中使用。如:She was late for school b
13、ecause she missed the bus=She missed the bus,so she was late for school Its not cheap,but its very good=Though its not cheap,its very good 2考例:1)I cant 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)ABecaus
14、e 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when,if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:1Mike wants to know if _ a picnic tomorrow YesBut if it _,well visit the museum instead(河北)Ayou have;will rain Byou will have;will rain Cyou will have;rains Dwi
15、ll you have;rains 2Do you know when he _ back tomorrow?Sorry,I dontWhen he _ back,Ill tell you(安徽)Acomes;comes Bcomes;will come Cwill come;comes Dwill come;will 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:1A:He is too young to go to school B:He is _young _ he cant go to school(四川)2A:Tom is the tallest in his class B:Tom is _ _ any other student in his class(四川)3A:The box is so light _ that the boy can carry it B:The box is light for the boy to carry(南京)4A:Put on your coat,or youll catch a cold B:_you _ put on your coat,youll catch a cold(上海),so,that,taller than,enough,If,dont,
