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)+that
2)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。

1. John fell asleep ________ he was listening to the music.
A. after B. before C. while D. 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. when B. while C. after D. 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. after B. unless C. while D. 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 rainy B. are going to, doesn’t rain
C. is going to, won’t rain D. 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 watched B. was doing; were watching
C. had done; were watching D. 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. when B. before C. while D. 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. So B. Though C. Since D. 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. where B. which C. that D. 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. when B. before C. since D. 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. after B. while C. when D. 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. unless B. until C. if D. after

A. see; goes B. will see; goes
C. will see; will go D. see; will go
答案:B。【解析】本题两个if意思不一样,第一个表示“如果”,引导条件状语从句,要用一般现在时代替将来时,第二个表示“是否”,引导宾语从句,故选D。

【答案详解】
1.答案:C。【解析】考查条件状语从句的时态,主句用将来时,从句用一般现在时。
2.答案:A。【解析】第一句是when引导的宾语从句,“他何时回来”是将来发生的事情,所以要用将来时态,第二句是由as soon as引导的时间状语从句,注意在时间和条件状语从句中必须用一般现在时代替将来时,故选答案A。
3. 答案:A。【解析】在if引导的条件状语从句中,要用一般现在时代替一般将来时,所以选A。
4.答案:B。【解析】四个选项都是引导时间状语从句的连接词,按照常理应该是“在你走之前把你的电子邮箱告诉我”,故选B。
5.答案:C。【解析】本句的意思是“如果公司不给我弟弟更多的薪水,他打算再找一份工作”,或“我弟弟打算再找一份工,除非公司给他更多的薪酬。” unless = if not 意为 “除非”;“如果不”,引导条件状语从句。
6.答案:D。【解析】由Yes可知“同意继续工作”,而排除C。选D,though引导的是让步状语从句。如果将Yes改为No,则选C。
7.答案:A。【解析】until引导时间状语从句,句意为“直到我亲眼看到了我才相信那个小Bob能在15秒内跑100米。”
8.答案:B。【解析】根据句意可以排除A和D,因为A和D在含义及语法上都说不通。如果选C,主句时态应为过去完成时。
9.答案:D。【解析】so that引导目的是目的状语从句。意思是“我很快完成了作业以便我能够早点睡觉。”
10.答案:B。【解析】although=though,汉语中可说“虽然…但是…”,但按英语习惯,通常不能说although…but… 或though…but…。因为,but是并列连词,要连接相同的句子成分,而although 和though是从属连词,引导的是让步主语从句。所以不可以与 but 连用。选B。句子意思为“虽然很危险,但我要试试。”
