中考英语状语从句考点归纳与例析【重点讲解】中考英语试题对状语从句的考查主要涉及引导状语从句的从属连词的用法。
单项选择题的四个选项往往是四个连词，这是状语从句最常见的考查形式。
另一个考点是状语从句中的时态，因此，在学习状语从句时要弄清状语从句的几个主要类别，如时间、地点、原因、条件、让步、方式、目的、结果等，同时记住它们的“引导词”及其相关意义。
考点一：引导状语从句的连词的选择。
1、引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/until, as soon as等。
其中when，while和as都可表示"当……时候"，但用法有区别:when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以是终止性动词,也可以是延续性动词。
例如:When I got home, he was having supper.as意为"边……边……"或"与……同时",重在表示两个动作同时发生。
伴随进行。
as从句是终止性动词时,主句通常也必须是终止性动词。
例如: They sang as they danced.while只可表示"段时间",从句谓语只限于延续性动词。
例如:While I was sleeping, my father came in.注意：从句谓语是持续性动词时,when，while和as可以互换。
主、从句谓语都是终止性动词时，when与as可互换。
从句谓语表示状态时，通常用while。
2、引导地点状语从句的常用连词是where。
例如：Where there is a will there ia a way.3、引导原因状语从句的连接词主要有because, as, since, for。
例如：Tom was late for school this morning because he didn’t catch the early bus.As he was not well,I decided to go there without him.Since this method doesn't work, let's try another.for表示所说的理由是一种补充说明，因此, for引导的从句一般不放在句子的开头。
例如:I decided to stop and have lunch, for I was feeling quite hungry.注意：because语气最强，as, since, for次之。
对于以why开头的问句，一般要用because引导的从句来回答。
4、引导条件状语从句的连接词主要有if, unless, as long as。
例如：If I am not busy tomorrow, I will play football with you.Unless you tried it, you can’t imagine how pleasant it is.5、引导让步状语从句的连接词有although, though, even if, even though。
例如：Although (though) I gave him some advice, he didn’t take them.6、引导方式状语从句的连接词有as, as if, as though。
例如：You should do your homework as Tom did.7、引导目的状语从句的连接词有so that, in order that。
例如：Cherry was walking quickly so that (in order that) she could arrived at the cinema in time.8、引导结果状语从句的连接词有so…that, such…that。
例如：He ran so fast that we couldn’t keep up with him.She spoke English so clearly that all of us could understand her.1）so…that（“如此…以致于”）表结果，其结构为：so+形／副＋that；so+形＋a(an)＋单数名词＋that；so＋many/much＋复数名词（不可数名词）+that2）such…that（“如此…以致于”）表结果，其结构为：such＋a(an)＋形＋名词＋that；such＋形＋复数名词／不可数名词＋that考点二：状语从句的时态。
1、在时间、条件、让步等状语从句中用一般现在时表示将来。
例如：If he has time, he will come to see you.2、before, after引导时间状语从句时，本身已能表达动作的先后关系，所以主从句都可用一般过去时代替过去完成时。
【中考链接】1. John fell asleep ________ he was listening to the music.A. afterB. beforeC. whileD. as soon as答案：C。
【解析】从句谓语用的是过去进行时，所以连词要用while。
选C。
2. Newton was playing under an apple tree ______ an apple fell onto his head.A. whenB. whileC. afterD. before)答案：A。
【解析】after和before表示时间的先后，用在此处不恰当。
while 不可与终止性动词连用，故选A。
本句中的when可译为“就在此时”。
3. Your dream won’t come true________you know what your dream is.A. afterB. unlessC. whileD. since答案：B。
【解析】根据主句、从句的意思和逻辑关系，本句只能填unless。
从句的意思是“除非你知道你的梦想是什么”。
选B。
4. James with the Greens _______ the White Tower Park if it _______ tomorrow.A. are going to, isn’t rainyB. are going to, doesn’t rainC. is going to, won’t rainD. is going to, isn’t rainy答案：D。
【解析】主句的主语是James（詹姆斯）为单数，with the Greens 是方式状语，根据主谓一致的原则，可排除A和B。
句中if引导的是条件状语从句，谓语要用一般现在时而不能用将来时，所以排除C选D。
5．I ________ my homework while my parents ________ TV last night.A. did; have watchedB. was doing; were watchingC. had done; were watchingD. would do; were watching答案：B。
【解析】while引导时间状语从句时，表示主句和从句谓语动词所表示的动作同时进行。
6．---Your picture is wonderful!--- I worked for 8 hours ________ I finished it.A. whenB. beforeC. whileD. after答案：B。
【解析】注意时间状语从句所表示的动作和主句的动作的先后关系。
“我工作了8小时才完成它”，即“在完成那幅画之前工作了8小时”，所以填before。
7．After school I found Mother was in bed sick. ________ Mother was ill, I should do something for her.A. SoB. ThoughC. SinceD. If答案：C。
【解析】since 引导的是原因状语从句，第二句的意思是“由于妈妈病了，我应该为她做些事情”。
8．The dog rushed to the nearest village ________ it could get someone to help his dying owner there.A. whereB. whichC. thatD. so that答案：D。
【解析】so that意为“以便，为了”，引导目的状语从句。
根据句意，“找人帮助它的快要死去的主人”是“这条狗冲进最近的村子里”的目的。
9．Xiao Li has worked here ________ he came here.A. whenB. beforeC. sinceD. while答案：C。
【解析】主句谓语是现在完成时，四个选项中只有since引导的从句才可与现在完成时连用。
故选C。
10．I arrived at the airport ________ the plane had taken off.A. afterB. whileC. whenD. before答案：A。
【解析】从句中两个谓语的时态可看出，“飞机起飞”的动作先发生，也就是说“I arrived at the airport”的动作是在“the plane had taken off”之后发生的，表明没有赶上飞机。
所以选A。
11. Usually we don’t realize how important nature is to us it is too late.A. unlessB. untilC. ifD. after答案：B。
【解析】not…until是固定搭配，意为“直到……才”，本句的意思是“我们通常很晚才认识到大自然对我们来说是多么重要。
”12. You’ll do much better ________ you’re more careful with your spelling.A. ifB. beforeC. althoughD. unless答案：A。
【解析】if表示“如果”。
