状语从句精讲—中考英语
【考点】考查时间、地点、原因、结果、目的、条件及比较状语从句。
在复合句中修饰主句中的动词、形容词或副词等的句子叫状语从句,在句中起到状语的作用。常考的状语从句有时间状语从句(由when,while,before,not…until等引导)、条件状语从句(由if,unless,as long as等引导)、原因状语从句(由because,since等引导)、结果状语从句(由so that,so…that…等引导)、目的状语从句(由in order that等引导)、让步状语从句(由though,although等引导)。引导状语从句的连接词是从属连词,状语从句可以在句首,也可以在句尾。
【精讲01】时间状语从句
时间状语从句在主句中表示时间,常用连接词有:when(当……时),while(当……时),as(当……时),before(在……之前),after(在……之后),since(自从),not…until(直到……才), as soon as(一……就),once(一旦……就)等。如:
I didn’t go to bed until I finished my homework. 我直到做完作业才去睡觉。
I can listen to the radio while I work. 我可以边听收音机边工作。
时间状语从句中,一般要用一般现在时代替一般将来时,一般过去时代替过去将来时。如:
I will telephone you when he comes. 他来时,我会给你打电话。
I’ll stay here until you come back. 我会呆在这里,直到你回来。
when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,从句的谓语可以是延续性动词,也可以是瞬间动词。如:
He was working when I went in. 我进去时他正在工作。
When she heard the news, she began to cry. 她听到这个消息,她哭了起来。
while引导的状语从句中常用延续性动词或表示状态的动词,意思是“在……期间”。 while还可以表示两者之间的对比关系。如:
They rushed in while we were singing. 我们唱歌时,他们冲进来。
I like playing football, while Tom likes listening to music. 我喜欢踢足球,而汤姆喜欢听音乐。
as引导状语从句,强调同时发生,不分先后。可以译成“随着”或“一边……一边”。 如:
John sings as he walks home. 约翰一边往家走一边唱歌。
since引导状语从句,主句常用现在完成时,从句常用一般过去时。如:
We have been friends since we met in Beijing. 自从我们在北京遇到就一直是朋友。
It has been six years since she left school. 自从她毕业已经有六年了。
until/ till 引导时间状语从句,当主句的谓语动词是瞬间动词时,主句常用否定形式,not…
until意思为“直到……才”。 如:
He didn’t go to bed until he finished his homework. 他直到做完作业才睡觉。
【精讲02】原因状语从句
原因状语从句在主句中表示原因或者理由。其连词有:because(因为),as (因为),since(既然)等。如:
I often eat carrots because they are good for my health. 我经常吃胡萝卜是因为对我的身体有好处。
As I don’t know the way, I had to ask the policeman. 由于我不知道路,所以我不得不问警察。
because表示因果关系语气最强,常用来回答why提出的问题。如:
I didn’t tell them because they were too young. 我没有告诉他们,因为他们太小。
because和so不能同在一个句子里。如:
Because the book was expensive, I didn’t buy it. (I 前不用so)
【精讲03】结果状语从句
结果状语从句在主句中表示结果。其连接词有:so…that…(如此……以至于……),such… that…(如此……以至于……)等。如:
It’s such a good chance that you can’t miss it. 这次机会如此好,你不能失去它。
such... that
such+a(an)+形容词+单数可数名词+that从句
such+形容词+复数名词/不可数名词+that从句 如:

=He is such a good doctor that everybody loves and respects him. 他是一位好医生,大家都尊敬并爱戴他。

【精讲04】条件状语从句
条件状语从句在主句中表示条件。
其连接词有:if(如果),unless (如果不,除非),as long as(只要)等。如:
If it is fine tomorrow, we will go swimming. 如果明天天气好的话我们去游泳。
在条件状语从句中,一般要用一般现在时代替一般将来时,一般过去时代替过去将来时。 如:

【参考答案】
1.A2.A3.D4.B5.D6.B7.C8.A9.C10.A11.B12.A
1.【详解】句意:当我正在吃饭的时候电视新闻报道了一场车祸。
考查连词词义辨析。while当……时;until直到……才;before在……之前;after在……之后。根据“I was eating”可知,此句是while引导的时间状语从句,故选A。
2.【详解】句意:我回家后会给你打电话,我希望给你打电话时,你能接我的电话。
考查主将从现和时间状语从句。when当……时候;so soon as表达不妥;as soon as一……就……。结合第一空前后语境可知,“When”引导时间状语从句,遵循主将从现的原则,所以第一空用一般将来时,排除选项C和D。根据第二空语境可知,作者希望当打电话给对方时,对方能接电话,因此用when来引导时间状语从句。故选A。
3.【详解】句意:当我们下车时,看见两个人正在打架。
考查连词辨析。Although虽然;But但是;Since自从,既然;As当……时,根据所给空后面的we got off the bus和后面的we saw two men fighting against each other可知,as最符合语境,故选D。
4.【详解】句意:自从杰克加入足球队以来,他对团队合作有了更多的了解。
考查从属连词辨析。until直到;since自从;while当……时候;though尽管,根据主句时态是现在完成时,从句时态是一般过去时,以及语境可知,应该是since“自从”引导的时间状语从句,故选B。
5.【详解】句意:如果明天不下雨,我们就去爬山。
考查条件状语从句。if引导的条件状语从句遵循主将从现,第一空是一般将来时,用will加动词原形,排除AB; climb the mountain“爬山”;第二空是一般现在时态,此处是否定形式,主语it是第三人称单数,本句含有实意动词rain,变成否定句要借助助动词does+not+动词原形,故选D。
6.【详解】句意:——我们今天能把这些树刷完吗?——不能,除非我们得到其他人的帮助。
考查连词辨析。if如果;unless除非;since自从;because因为。“we get others’ help”是条件,除非得到帮助,否则没办法完成,故选B。
7.【详解】句意:——只要我高兴,我父母不介意我做什么工作。——他们真的是很善解人意的父母。考查连词。even though尽管;as soon as一……就;as long as只要;as though好像;分析空格前后句可知,此处表达的是只要我开心,父母不介意我做什么,as long as“只要”,是引导条件状语从句的连词,故选C。
8.【详解】句意:尽管露西和莉莉是双胞胎,她们有一些不一样。
考查连词。So因此;but但是;and和。根据“Although Lucy and Lily are twins”可知句子表达 “虽然……但是”,“although”和”but”不能在句子中同时使用。故选A。
9.【详解】句意:杰克虽然取得了很大的成就,但他仍在按照高标准工作。
考查连词辨析。until直到;if如果;though尽管;since因为。观察句子前后关系“他仍在按照高标准工作”和“杰克取得了很大的成就”可知应该是though引导的让步状语从句,故选C。
10.【详解】句意:不管别人怎么说,你只要选择你喜欢的。
考查让步状语从句。no matter what无论什么;whatever无论什么;No matter how无论怎样;however无论怎样。根据“others may say”,可知,不管别人说什么,排除C和D选项。第二个空要做动词like的宾语,而no matter what只能引导让步状语从句,排除B选项,故选A。
11.【详解】句意:我们不在操场上打篮球,因为外面下雨。
考查连词辨析。so所以;because因为;and和;but但是。分析空格前后句可知,此处构成因果关系,空格后表示原因,用“because”。故选B。
12.【详解】句意:——你觉得昨天的英语演讲怎么样?——嗯,他说得太快了,我跟不上。
考查连词辨析。so…that…如此……以致于……;both…and…两者都……;too…to…太……而不能……;as…as像……一样。根据“he spoke…fast…I couldn’t follow it. ”可知,他说得太快,以致于我跟不上。故选A
