1、中考初中英语状语从句精讲及练习合集中考初中英语状语从句精讲及练习什么是状语从句呢，所谓的状语从句，就是用一个句子在复合句中作状语，修饰主句中的动词、形容词、副词等。状语从句可以放在主句之前，也可以在主句之后。放在主句之前时，常用逗号与主句分开；放在主句之后，不用逗号。 状语从句在初中阶段主要有：时间状语从句、条件状语从句、原因状语从句、结果状语从句、目的状语从句、让步状语从句和比较状语从句等。下面我们就结合2019年中考英语试题来详细讲解这些状语从句的用法及考点情况。考点一：时间状语从句时间状语从句主要常用引导词when,while,before,after, as soon as, unti
2、l(till),since, as等引导，详见下表：时间状语从句的引导词用法说明同义转换结构示例说明when“当时候”，when引导的时间状语从句的动作和主句的动作可以是同时发生，也可以是先后发生。when既可以指时间点，也可以指时间段。主句+when+从句=When+从句，主句How did you try to get to school on time when you missed the school bus ?当你美赶上小车时，怎么设法准时到达学校呢When you grow up in the future ,you will understand what I said. 当你
3、将来长大的那一天，你就会明白我说的话。Mother was cooking when I got home.我到家的时候，母亲正在煮饭。如果主句为一般将来时，when引导从句谓语动词使用一般现在时。如果主句为过去进行时，when引导的从句谓语动词使用一般过去时。while“当时”，while引导时间状语从句中，谓语动词必须是延续性动词。如果从句谓语动词为非延续性动词，则须用进行时态。主句+while+从句=While+从句，主句While she was watching TV in the sitting room , the bell rang.她正在客厅里看电视的时候，铃声响了（watc
4、h为非延续性动词）。Mike often went to watch the Beijing Opera while he stayed in Beijing.迈克在北京期间，经常去看京剧（stay为延续性动词）。before“在之前”，从句表示主句的动作发生在从句的动作之前。主句+before+从句=Before+从句，主句Your picture is wonderful ! I worked for 8 hours before I finished it . -你的画太好啦！-画作在完成只前我画了8个小时。He had studied in this school before he
5、joined the army. 参军之前， 他在这学校学习过。如果主句为一般将来时，before引导从句谓语动词使用一般现在时。如果主句的谓语动词早于从句的谓语动词发生，主句谓语用过去完成时。after“在之后”，从句表示主句的动作发生在从句动作之后。主句+after+从句=After+从句，主句What are you going to do after you finish your college?你大学毕业后打算作什么呢？After he did his homework, he left the classroom.他作业完成后，离开了教室。如果主句为一般将来时，after引导从句
6、谓语动词使用一般现在时。until(till)“直到才”.not.until+从句=.not.before+从句=主句（肯定句）+after+从句My grandma didnt go to sleep until I got back home.=My grandma didnt go to sleep before I got back home.=My grandma went to sleep after I got back home.我奶奶直到我回家才去睡了觉。如果主句谓语动词为延续性动词，主句使用肯定句； 如果主句谓语动词为非延续性动词，主句须为否定句形式，until(till)
7、意思是“直到才”。till引导的从句不可谓语主句前。Not until谓语句首时，要用倒装语序。as soon as “一就”主句+the moment that+从句Ill call you as soon as I get to Beijing.=Ill call you the moment that I get to Beijing.我一到北京就给你打电话。如果主句为一般将来时，as soon as引导从句谓语动词使用一般现在时。since “自从”，表示动作的起点，从句中动词用一般过去时。 主句表示动作的延续，用现在完成时。主句+since+从句主句+since+过去时间点=主句+f
8、or+段时间=It is+段时间（段时间+has passed）+since+从句He has studied the problem since he graduated from the college.他从大学毕业就在研究这难题。The Green have lived in Shanghai since 2009=The Green have lived in Shanghai for 10 years.=It is ten years since the Green lived in Shanghai.=Ten years has passed since the Green liv
9、ed in Shanghai.格林一家从2009年起就居住在上海。【典型考例1】（2019内蒙包头）It was the middle of the night _the sound of the piano woke me up. A. because B. if C. when D. although【析】正确答案：C。句子意思是：钢琴声把我吵醒时，正式午夜时候。Because“因为”引导原因状语从句，if“如果”，引导条件状语从句；although“虽然”，引导让步状语从句。根据句意可知，本句主要说明的是钢琴声吵醒我的时间，所以选用when“当时”引导时间状语从句说明时间。【典型考例2】
10、（2019四川凉山州） did the rainstorm come?While we a physics lesson yesterday.A. When; have had B. While; are havingC. When; were having D. While; have【析】正确答案：C。句子意思是：-暴雨什么时候来的？-昨天，我们正在上物理课的时候。前一句问时间，所以用when来构成特殊疑问句，第二句说明暴雨来临时，我们正在做什么，故用过去进行时。【典型考例3】（2019四川南充）-Daddy, when will we go out to fly a kite? -As
11、soon as the rain_ A. is stopping B. stopped C. will stop D. stops【析】正确答案：D。句子意思是：-爸爸，我们什么时候出去放风筝？-雨一停，我们就出去放。第二句为省略了主句，根据上一句可知主句为We will go out to fly a kite.我们知道主句为一般将来时的时候，以as soon as 引导的时间状语从句中的谓语动词使用一般现在时，所以正确答案为D。【典型考例4】（2019广西桂林）He hasnt communicated much with his parents since he _ a mobile p
12、hone last year. A.got B.get C.gets 【析】正确答案：A。句子意思是：从去年他买了一部手机起， 他就没有跟父母进行太多的交流。因为主句谓语动词为现在完成时，所以since引导的时间状语从句中的谓语动词使用一般过去时，故正确答案为A。【典型考例5】（2019天津）While the lights _to red, a car suddenly appeared round the corner A. change B. have changed C. were changing D. will change【析】正确答案：。句子意思是：【典型考例6】（2019四川
13、广元）They didnt go home _ they finished their work.A. because B. when C. until【析】正确答案：C。句子意思是：他们完成了工作才回家的。because“因为”，引导原因状语从句；when“当时”，引导时间状语从句；until“直到才”，引导时间状语从句。因为说话人强调一个动作的结束另一个动作才开始的时间，因此不能选because来引导原因状语从句，而until正好引导的时间状语从句表示的是一个动作的结束而另一个动作的开始，所以选C。【强化练习】1、单项选择1（2019湖北鄂州）-Son, you have never be
