中考英语语法状语从句考点(中考真题例题)

中考英语语法:状语从句一、时间状语从句在时间状语从句中,通常要用动词的一般现在时态表示将来时,用一般过去时表示过去将来式。

时间状语从句常用连词有:when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。

1.考查when, while, as引导,表示“当……时候”.【考例】一Mum,____shall we have lunch?——We will have it when your dad__________. [07连云港市]A when;returnsB where returns C.where;will return D.when;will return[答案]A.[解析] 答语中when引导了一个时间状语从句,主句用了一般将来时态,所以从句用一般现在时态,可见正确答案在A与B之中。

既然答语用了时间状语来回答,可见问句询问的也一定是时间,从而确定正确答案为A。

2. before 的用法:before的本意为“在……之前”,根据具体语境还可理解为“还没来得及/还没有……就……,趁着还没……就……,不知不觉就……,……才……”等。

如:【考例】Could you please give me your e-mail address _________you go? [昆明市] A. as soon as B. before C. after D. until [答案]B.[解析]这四个词(组)都可以引导时间状语从句,as soon as一……就.before 在……之前;after在……之后;until直到……才。

分析句子可以看出句意为“在你走之前把你的电子邮件地址给我好吗?”2.until 和till 的用法:与肯定式的主句连用,主句谓语必须是延续性动词,till/ until 表示“……直到……”;与否定式的主句连用,且主句谓语是非延缓性动词时,till/ until表示“直到……才……”。

其强调句型为“not…until”,位于句首时要采用倒装形式。

如:【考例】一Hurry up.The bus is coming.——Oh。

no.We mustn't cross the street ____the traffic lights are green.[福州市] A.after B since C while D.until[答案]D .[解析]本题应从句意人手。

until常用于否定句中,构成"not…until"结构,意为“直到……才……”,该句意为“直到交通灯变绿,我们才能穿过马路”。

The kids didn't start to fly kites in the playground _________the rain stopped. [成都市]A. ifB. untilC. whenever[答案]B.[解析] not…until…直到……才。

“直到雨停孩子们才可以去操场放风筝”,--Look! Here comes our school bus.--No hurry. Don't get on it _________it has stopped. [安徽省]A. untilB. afterC. sinceD. whenA.[解析]句中有don't,可想not...until为固定结构,意为“直到……才……”。

二、条件状语从句引导条件状语从句的从属连词有if ,unless(=if …not如果不……,除非),as/so long as ,while(=as long as 只要),supposing(that),provided/providing(that),in case(假使),on condition that(在……的条件下)等。

如:【考例】__you go to bed earlier, you won't feel tired in the mornings.[沈阳市] A.Unless B Because C.IfD.When[答案]C .[解析]考查if引导的条件状语从句。

“假如你早一点上床睡觉,那么你在上午就不会感到累。

”You won't pass your exams ___________ you work harder. [广东省]A. whenB. ifC. unlessD. after[答案]C .[解析]when,after一引导的是时间状语从句,不合题意;if,unless引导的是条件状语从句,If不合句意,“除非你更加努力地学习,否则,你不会通过考试”。

故用unless。

三、让步状语从句用来引导让步地点状语从句的从属连词有:though,although,even if/though,while(虽然、尽管),for a11(that)(尽管)whether...or(不论/不管……还是……))以及“疑问词+ever(whatever,wherever,whoever,however,)”和“no matter +疑问词”等。

【考例】—Shall we go on working?—Yes , I prefer to have a rest . (2004江西省南昌)A.when B.if C.because D.though[答案]: D[命题立意]:本题考查从属连词引导让步状语从句的用法。

[试题解析]:依据上句:我们继续工作吗?是的,尽管我想休息会。

[试题解析]:依据题意:即使爱迪生失败多次,他也决不放弃。

though用来引导让步状语从句。

故选B。

四、目的状语从句引导目的状语从句的从属连词有so that , in order that (为了,以便);in case(以防,以免),lest(免得,以防),for fear that(以免,惟恐)等。

从句中一般含有can , could, may,might ,will, would等情态动词。

如:【考例】一More and more people in Beijing are learning English _______they can better serve the 2008 0lympic Games.一I'm sure they will.[宜昌市]A.because of B so that C.even though D.as if[答案]B.[解析] 本题也应从句意人手。

越来越多的人学习英语,“为的是”能更多更好地为奥运服务。

so that引导一个目的状语从句。

五、结果状语从句【考例】The camera is expensive I can’t afford it. (2004辽宁本溪)A. so, thatB. such, thatC. so, as toD. enough, that[答案]: A[命题立意]:本题考查从属连词引导结果状语从句的用法。

[试题解析]:依据题意:这照相机太贵以致我买不起。

expensive为形容词,so…that…句中要用形容词或副词;such…that…要用形容词修饰名词。

其他两项不能引起从句。

故选A。

【语法回顾】状语从句的分类。

1. 时间状语从句用法要点。

soon as, while 等,具体用法如下:1. when 意为“当……时”,引导时间状语从句,表示主句的动作和从句的动作同时或先后发生。

例如:I feel very happy when you come to see me. 你(们)来看我时,我感到很高兴。

When you are crossing the street, you must be careful. 你(们)过街道时,一定要小心。

when引导的时间状语从句,when的从句可以用延续性动词,也可以用点动词。

例如:He was working at the table when I went in. 当我进去的时候,他正在桌旁工作。

Someone knocked at the door when I was sleeping. 当我正在睡觉时,有人敲门。

I will visit my good friend when I have time. 当我有空儿时,我将去看望我的好友。

I worked for a foreign company when I was in Shanghai. 当我在上海时,我为一家外国企业工作。

注:when也可以作并列连词,表示一个动词正在进行的时候,突然间发生了另外一件事。

I was fishing by the river , when someone called for help. 我正在河边钓鱼,就在那时有人求救。

We were working in the chemistry lab, when the lights went out. 我们正在化学实验室工作,突然灯都熄灭了。

2. before 意为“在……之前”,引导时间状语从句时,表示主句的动作发生在从句的动作之前。

例如:We cleaned the classroom before we left school yesterday.昨天离开学校之前,我们打扫了教室。

He had been a cook before he went to college . 他上大学前曾当过厨师。

after 意为“在……之后”,引导时间状语从句时,表示主句的动作发生在从句的动作之后。

例如:After you use plastic bags, you mustn't throw them about. 你(们)用过了塑料袋之后,不准到处乱扔。

He called me after he had finished his work. 他在工作完之后给我打了个电话。

注:若主句和从句两个动作发生的先后顺序十分接近,那么也可以不用完成时态,例如上面的第二句可改成:He called me after he finished his work.3. since引导的时间状语从句,译为“自从……”,主句常用现在完成时,从句常用一般过去时。
