【考点解读】
重点把握引导并列句和时间、地点、条件、让步、比较、原因状语从句的连词的灵活运
用。掌握状语从句的时态、语态、语气和省略
【命题规律】
考查考生对不同类型从句的辨别能力,与其他从句、句型结合起来一起考查近年高考的
发展趋向:从属连词在具体语境中的运用,及从属连词词义的延伸。设问角度越来越多样化。
【备考策略】
考生要具备全面的状语从句的知识,熟悉每个连接词的语义和运用特征,注意把握并列
连词的用法,研读近几年高考题中的状语从句,提高运用状语从句的能力。
一、并列连词
1.表示并列关系的连词:
and: 可用来连接两个或两个以上的单词/短语或句子,表示一种顺接的关系。
☞He helps me and I help him. 他帮我,我帮他。
both…and:"两个都……",连接两个并列主语时谓语动词用复数。
☞Both Li Ping and Mary are going to the Great Wall tomorrow.
neither…nor: "既不……也不……",连接的并列成分可在句中作主语、表语、宾语等。
连接并列成分
作主语时,谓语动词通常与 nor 后的部分保持一致。
☞Neither he nor I am right.
not only…but also: "不仅……而且……",强调后者;引导并列主语时,谓语动词与后
面的主语保持
一致。
☞Not only the students but also the teacher gives the money to our
school.
2. 表示选择关系的连词:
or:用于否定句中连接并列成分,表示"和,与";用于"祈使句+or+陈述句"中,意
为"否则,要不
然"。
☞The baby is too young. He can’t speak or walk.
either…or…:"要么……要么",连接的并列成分可在句中作主语、表语、宾语等。连接并
列成分作主语时,谓语动词通常与 or 后的部分保持一致。
☞Either Tom is coming or his sisters are. 不是汤姆就是她的姐妹们要来。
3. 表示转折关系的并列连词
but "但是",所连接的成分意思相反或相对。
Our school is small but beautiful.
while "然而,可是",表对比。

状语从句通常由从属连词或起连词作用的词组引导,有时甚至不需要连词直接和主句连
接起来。状语从句根据它表达的意思不同,可分为时间、地点、原因、目的、结果、条件、
方式、比较、让步等九类。状语的位 置比较灵活,可以位于句首、句末或句中。enough 用
作状语修饰形容词和副词时必须后置。
一、 时间状语从句
时间状语从句是表示时间关系的从句。可以引导时间状语从句的连词很多,根据意义和
主从句之间的时间关系,通常可分为以下几种情况:

when, while, as 表示主句谓语作和从句的谓语动作同时发生或几乎同时发生。
1.when
①when 表示点时间时,从句中用短暂性动词;表示段时间时,用持续性动词。

我到家的时候,全家已在吃晚饭。(when 表示点时间)
►When they were still talking and laughing, the teacher came in.
当他们还在说笑的时候,老师进来了。(when 表示段时间)
②有时 when 表示虽然,尽管的含义,相当于 although 或 since。

►How can you hope for mercy yourself when you show none?
既然你不宽恕别人,你自己又怎能希望得到别人的宽恕呢?
2.while
①while 通常表示一段时间,从句中宜用持续性动词作谓语。
►Strike while the iron is hot.趁热打铁。
►She fell asleep while she was reading the newspaper.她在看报的时候睡着了。
②while 有时可以作并列连词,表示对比,可译成……而……。

③while 有时可引导让步状语从句,意思是虽然。

活泼了。
提示:
状语从句可放在主句之前或之后,放在主句之前时一般用逗号与主句分开。有时可置于
主句中间,前后用逗号。
b.when 更强调特定时间,还可表示从句中的动作先于或后于主句的动作。
►When I had given Mary the spare ticket, I found my own already gone.
当我把多余的票给了玛丽时,我才发现我自己的票已不知去向。(从句动作发生在主句之前,注

比较:
because 和 for 的区别:

【易混辨析】because, since, as

用逗号隔开。在
回答 why 引导的特殊疑问句时,或在强调结构 It is/was ..that 和关联词 not ..but 引导的原
因状语从句中,
要用 because。另外,because 还常和副词 just, merely 等连用。

四、目的状语从句
目的状语从句是表示行为目的的从句。引导目的状语从句的主要连词有 that, so,so that,
sothat, in order that 等,从句中常常使用一些情态动词,如 can, could, may, might, should 等。
(一)that, so that,in order that 表示为了,以便,一般放在主句之后。that 语气较弱,用
的较少,多用 so that。 ►Let's take the front seats that we may se more clearly.我们坐前

饭是为了生存。 ►They hurried so that they might not miss the train.他们为了不误火
车,才急急忙忙的。
►In order that everyone might hear her clearly, she raised her voice again.

►As long as we don't lose heart, we'll find a way to overcome the difficulty.
只要我们灰心,我们就能找到克服困难的方法。
►You may use the room on condition that so long as you clean it afterwards.
只要你用完后打扫干净,你就可以使用这个房间。
3. in case
in case 既引导目的状语从句,也可以引导条件状语从句,等于 if it happens that。
►In case I forget, please remind me of my promise.如果我忘了,请提醒我所做的承诺。
4. Providing, provided that, supposing, suppose that, given that 这几个短语意思相近,有如
果,只要,假如等意思。
►Given that they are inexperienced, they've done a good job.
考虑到他们缺乏经验,他们的工作已做得很好了。(that 可以省略)
七、方式状语从句
方式状语从句是描述动作方式的从句。方式状语从句常由 as, as if,as though 等词引导,
通常位于主句之后。
1. as, just as 这两个连词的意思是如……,正如……一样。just as 比 as 语气要强一些。
►Do in Rome as the Romans do.入乡随俗。
►Balloons float in the air just as boats do on the sea.气球在空中就如同船浮在海面上一
样。
注意:
在口语中,还可用 like 来代替 as,引导一个方式状语从句。
►She is doing the work exactly like I want her to.她正在完全按照我要她的那样在做这项
工作。
►Do you make bread like you make cakes 你做面包的方法是不是和做点心一样?
2. as if, as though
由 as if 或 as though 引导的状语从句可以用陈述语气表示可能符合事实的情况,也可以
用虚拟语气的过去式表示现在不符的或与事实相反的情况。
►She looks as if she is ill.看上去她好象是生病了。
►The boy plays piano as though he has a natural ear for music.
这孩子弹起钢琴来家好象天生很懂音乐似的。
►They talked loudly as if nobody were around.他们大声说话仿佛周围没人似的。
►He acted as ifthough nothing had happened 他装得似乎什么事也未发生过。
八、让步状语从句
让步状语从句表示在某种相反的条件下,主句中的情况依然会出现。让步状语从句由
although, though, however, whatever, whoever, whomever, whichever, whenever, wherever,
whether(是否), no matter (who, wha, etc), even if, even though 等词引导。
1. although, though 这两个词意思一样,都解释虽然,尽管。although 比 though 正式。
►Although he is young, he is very clever.他尽管年轻,但很聪明。
►Though he is poor, he is happy.他虽然穷,但很快乐。
提示:
有时 though= and yet 但是,然而,放在句子末尾,前面用逗号。
It was hard work; I enjoyed it, though.那工作很苦,但是我喜欢干。(= It was hard work, but
I enjoyed it.)
2.though 从句有时可以倒装,将从句中的一部分提置句首。
►Child though he is, he knows a lot. 尽管他是个孩子,他懂得的东西却很多。(=Although
he is a child, he
knows a lot.)= Child as he is, he knows a lot.
►Strange though it may look, it is true. 尽管看起来奇怪,但是却是真的。
(= Though it looks strange, it is true.)
注意:
although, though 不能与 but 连用,但是可以与 yet, still, nevertheless 连用。
Although/Though he blames me, yet I will trust him.尽管他责怪我,但我还是愿意信任他。
3. Even if, even though
►We won't be discouraged even if though we fail ten times.我们就是失败十次也不泄气。
►Even if though you fail, you will have gained experience.纵然你失败,你也会得到一些经
验。
4. while, whereas
这两个词也可引导让步状语从句,突出主句和从句的对比。
►While I understand what you say, I can't agree with you.虽然我理解你的意思,但我还是
不同意。
►Some people like fat meat, whereas others hate it.有些人喜欢肥肉,相反有些人讨厌肥
肉。
5. no matter (who, what, where, when, etc) 这几个词引导的让步状语从句语气十分强烈。
►This is not true, no matter who says so.不管谁这么说,都不对。
►Do it no matter what others say.不管别人怎么说,尽管干。
►No matter how bus he was, he studied English every day.不管他多忙,他都每天坚持学习
英语。
6. Whether...or (not) ... whether...or (not) ...意思是不管……还是……。
►Whether you believe it or not, it's true. 不管你信不信,这是真的。
►Whether the weather is good or bad, they will set off as planned.
不管天气是好还是坏,他们都要按计划启程。
1. It's much easier to make friends ________ you have similar interests.
A. unless B. when C. even though D. so that
【参考答案】B
【答案解析】考查状语从句。由句意"当你们兴趣相投时,交朋友就容易多了"可知,这里
应该用 when 引导时间状语从句。
2. I took my driving license with me on holiday, ________ I wanted to hire a car.
A. in case B. even if C. ever since D. if only
【参考答案】A
1. 状语从句同时具备下列两个条件:
①主句和从句的主语一致,或从句主语为 it;
②从句主要动词是 be 的某种形式。从句中的主语和 be 动词常可省略。
►When ( the museum is ) completed , the museum will be open to the public next year .
►He’ll go to the seaside for his holiday if (it is ) possible.
2. 状语从句的"简化"现象常存在于以下五种状语从句中:
①由 if, unless 等引导的条件状语从句;
②由 although, though, even if / though 等引导的让步状语从句;
③由 when, while, as, before, after, until / till 等引导的时间状语从句;
④由 as, as if 等引导的方式状语从句;
⑤由 as, than 等引导的比较状语从句。
下面针对这五种情形作一归纳。
(1)当状语从句的主语是 it,且谓语动词是 be 时,it 和 be 要完全简化掉。
►If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。
►You must attend the meeting unless (it is) inconvenient to you.
除非情况对你来说不方便,否则你必须出席这次会议。
(2)当状语从句的主语和主句的主语一致时,从句可以将主语和 be 动词简化掉。常用于以下几
种情形:
a.连词+形容词
►As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车。
►Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。
b.连词+名词
►Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,而现在是位
著名的导演了。
c.连词+现在分词
►Although (he is) doing his best in maths these days, he has still got no good marks.
尽管近来他一直在学数学,但他仍然没有取得好成绩。
d.连词+过去分词
►He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去
那里。
►The concert was a great success than (it was) expected.这场音乐会出乎意料地取得了巨
大成功。
e.连词+不定式
►He stood up as if (he were) to say something.当时他站起来好像要说什么。
►He wouldn't solve the problem even if (he were) to take charge.即使他来负责,他也解决
不了这个问题。
f. 连词+介词短语
►She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦。
►He had mastered the English language before (he was) in the USA.他到美国之前就懂英
语了。
注意:
当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表
达。如:
►When the meeting was over, all the people went out of the meeting-room.
当会议结束时,人们都走出了会议室。
(2015·北京)If _________for the job, you’ll be informed soon.
A .to accept B. accept C. accepting D. accepted
【参考答案】D
【试题解析】考查状语从句的省略。句意:如果录用你了,我们将很快通知你。分析句子结
构及选项可知,If _________for the job 是状语从句的省略。且主语 you 与 accept
之间是动宾关系,故用过去分词形式。答案为 D。

a passion is to life.
One day I went with Mum to drop my sister off at the gym. Then, 3 Mum stopped at a
red light, someone on the roadside caught my eyes. It was a man 4 (dress) in rags,
homeless. That didn't interest me, 5 I had seen many like him before.
6 the man wasn't sitting down with a sad expression. He had a radio in his hand and
was dancing merrily to the music. The radio seemed to be the most precious thing 7 he
had.
“Mum, why does that man have a radio 8 he's homeless?”I asked.
“He bought it,”she replied.
“But 9 he's homeless, why doesn't he use the money to buy food or clothes? He
wasted it on something he doesn't need.”
“Well, Sarah, sometimes food and clothes aren't the only important things. We need
happiness, too.”
“I see.”The man must care too much about music, 10 he bought a radio instead of
food and clothes. I realized that happiness is the key to life. Without it, there's nothing to look
forward to. A passion gives a person the happiness they need to keep going!
【语篇解读】这是一篇故事。本篇短文主要通过一位衣衫褴褛、无家可归、食不果腹的
