专题3 状语从句
一．语法概念巧掌握：
（一）概念
状语从句主要用来修饰主句或主句的谓语。一 ( http: / / www.21cnjy.com )般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。 现分别列举如下:
1、时间状语从句

10. 状语从句的简化
状语 ( http: / / www.21cnjy.com )从句的省略
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。例如：
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.
另外，比较状语从句经常省略。例如：
I’m taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。
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。例如:
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。
Whenever (she is) free, she often goes shopping.她有空就去逛商店。
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
While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人。
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
As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。
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。
二．解题方法灵活用
解题方法或策略：
1．全面了解状语从句的知识，熟悉每个连接词的语义和用法，同时了解个别连接词的多种意思。
(1)as,since等连接词的用法比较灵活，既可以引导时间状语从句，又可以引导原因状语从句。
例1 “You can't have this foot-ball back——you promise not to kick it at my cat again,”the old man said firmly.
A．because B．since C．when D．where
解析：本题的主句意为“你不能把足球拿回去”，从句意为“你答应过不再用足球踢我的猫”。根据其逻辑，从句为原因状语从句，答案应为B(since在此处意为“既然”，而不是“自从”)。
(2)注意before,until,unless等连接词的英语 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )原意与符合中文习惯的表达方式之间的差距。
例2 The American Civil War lasted four years——the North won in the end.
A．after B．before C．when D．then
解析：本题的主句意为“美国内战持续了4年”，从句意为“北方最后取得了胜利”。根据其逻辑，整个句子意为“美国内战持续了4年，北方才最后取得了胜利”，故答案为B(before在此处意为“才”，而不是“在……之前”)。
2．解题时，要分清状语从句与其主句之间 ( http: / / www.21cnjy.com )的关系，正确理解整个句子的逻辑，才能选出正确的答案。
例3 —Did Jack come back ear-ly last night
—Yes.It was not yet eight o'-clock——he arrived home.
A．before B．when C．that D．until
解析：本_题是一段时话。根据“Yes”’的回答，可得知Jack很早就回家了，即“Jack回家的时候还不到8点钟”，答案为B。
例4 You must keep on workingin the evening——you are sure you can finish the task in time.
A．as B．if C．when D．unless
解析：本题前一个句子要求“晚上继续工作”，后一个句子意为“确信能按时完成任务”。按照本题的逻辑，可知句意为“你们晚上必须继续工作．除非你们确信能按时完成任务”，故答案为D。
3．学会区分意思相近的连接词和拼写相似的连 ( http: / / www.21cnjy.com )接词。
在同类状语从句中，有一些连接词的意义和用法很接近。如引导时间状语从句的when/as/while，都有“当……时候”的意思，但在表示“随着”的意思时只能用as，表示“突然”时要用when，表示“正当……”时一定要用while。引导原因状语从句的because/as/since都有“因为”的意思；引导让步状语从句的although/though/as意思都为“虽然，尽管”；no matter/whatev-er/however意思都为“无论，不管”。同学们一定要学会分辨其中的细微差别，否则解题时很容易犯错。
此外，像if和even if, though和as though,as long as和as far 这几组连接词看似相似，实际上其意各不相同，被用来引导不同的状语从句。
例5 Allow children the space tovoice their opinions，——they are dif-ferent form your own.
A．until B．even if C．unless D．as though
解析：本题考查让步状语从句的连接词。根据句子的逻辑，可得知句意为“即使孩子们的观点与你的一样，也要让他们说出来”。even if意为“即使”故答案为B。
例6 He tried his best to solve the problem,——difficult it was.
A．however B．no matter C．whatever D．although
解析：本题提供的四个选项都可以引导状语从名。从句子的语序来看，由于although引导的从句没有倒装现象，可以先排除D。A、B、C三个选 项都有“无论、不管”的意思：however意为“无论怎样”，no matter意为“无论”，whatever意为“无论什么”。整个句子意为“无论问题怎样困难，他还是尽力解决”，故答案为A。

解析 前半句句意为：有人给你打电话，后半句句意为：没有人知道我在这儿。根据句子意思可知前后两句明显为转折关系，因此选C项。
4答案 D
解析 考查状语从句。dress作及 ( http: / / www.21cnjy.com )物动词时，宾语为人；本题中的dress为不及物动词，所以后面应该接一个状语从句。答语句意为：你想怎么穿都行。
5答案 D
解析 句意为：每一次发生火灾，他总是第一个到达现场。every time用作连词，引导时间状语从句。
6答案 B
解析 while并列连词，意为“而，却”，表示转折。
7答案 C
解析 句意为：工程师们都很忙，以致于他们没有时间去做户外运动，即使他们有兴趣。even if即使，符合句意。
8答案 D
解析 考查连词。句意为：如有需要，不要害怕向老师求助。此处when相当于if，表示条件，其他不符合语意。
9答案 C
解析 分析前后分句逻辑关系，是条件或假设关系，而且“祈使句＋and/or/otherwise＋陈述句”是固定句型，所以选C项。
10答案 D
解析 句意为：如果你在一个风俗习惯与你的风俗习惯完全不同的地方旅游，请入乡随俗。此处用where引导地点状语从句。
11答案 D
解析 考查whatever引导的让步状语从句。whatever＝no matter what修饰名词weather。
12答案 C
解析 句意为：约翰篮球打得很好，然而他最喜欢的运动是打羽毛球。四个选项中表示转折的连词只有yet。
13答案 C
解析 考查状语从句。根据语意“我到新华中学的校门口时才知道这学校的准确地址”可知C项正确。
14答案 C
解析 考查状语从句。句意为：如果你没体验过，你不会知道我的感受。unless＝if not如果不，引导条件状语从句。
15答案 D
解析 考查It’s...since ( http: / / www.21cnjy.com )...结构，表示动作自过去发生至今有多久。但该结构从句中谓语动词的性质决定最终的意义。从句中谓语动词为瞬间性动词，则表该瞬间动作发生至今时间多久；若从句中谓语动词为延续性动词，则表示该延续动词动作终止至今时间多久。work属延续性动词，该句句意为：她不在这儿工作已经有两个多月了。显然，本题的答案为D项。
16答案 C
解析 根据句意“无论你有多么 ( http: / / www.21cnjy.com )严重的问题，你都应该鼓起勇气面对挑战。”，而however表让步时其顺序应是：however＋形容词＋主语＋谓语。however作连接副词，相当于no matter how，后接形容词或副词，意为“无论，不管”，引导让步状语从句，其顺序为“however＋形容词、副词＋主语＋谓语”。
17答案 A
解析 前后两个从句都表示地点的含 ( http: / / www.21cnjy.com )义。是定语从句还是地点状语从句，做题的关键是看有没有表示地点的名词作先行词。如果有表示地点的名词，就是定语从句；如果没有便是地点状语从句。该题中第一个从句为地点状语从句，第二个从句为定语从句，因此答案为A项。
18答案 C
解析 考查连词的用法。句意为：尽管没 ( http: / / www.21cnjy.com )有法律规定你怎样穿戴，但是并不是所有的时尚都是值得尊敬的。while尽管，符合句意。because因为；since既然；unless除非。
19答案 B
解析 本句为“祈使句＋and/or＋陈述句”句型。根据题意，应为顺承关系。故选B项。
20答案 D
解析 此处as引导让步状语从句，此时常把作表语的形容词提前到句首。
21答案 D
解析 so long as意思是“只要”，引导条件状语从句。
22答案 A
解析 句意为：明天请安排一次对经理的采访，或者在他方便的任何时间。本句的后半句句子完整，所以应该使用连接副词，结合句意可知应选A项。
23答案 B
解析 when此处为并列连词，相当于at that time，可译为“这时(突然)……”。
24答案 B
解析 空格后的句子是空格前句子的目的，所以用so that。句意为：目标应该现实一点，这样学生们就能实现它，并有成就感。21世纪教育网版权所有
25 答案 B
解析 句意为：他发现读书越来越困难，因为他的视力开始下降。for表示原因，符合句意。

专题3 状语从句
一．语法概念巧掌握：
（一）概念
状语从句主要用来修饰主句或主句的谓语。一 ( http: / / www.21cnjy.com )般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。 现分别列举如下:
1、时间状语从句

10. 状语从句的简化
状语 ( http: / / www.21cnjy.com )从句的省略
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。例如：
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.
另外，比较状语从句经常省略。例如：
I’m taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。
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。例如:
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。
Whenever (she is) free, she often goes shopping.她有空就去逛商店。
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
While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人。
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
As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。
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。
二．解题方法灵活用
解题方法或策略：
1．全面了解状语从句的知识，熟悉每个连接词的语义和用法，同时了解个别连接词的多种意思。
(1)as,since等连接词的用法比较灵活，既可以引导时间状语从句，又可以引导原因状语从句。
例1 “You can't have this foot-ball back——you promise not to kick it at my cat again,”the old man said firmly.
A．because B．since C．when D．where
解析：本题的主句意为“你不能把足球拿回去”，从句意为“你答应过不再用足球踢我的猫”。根据其逻辑，从句为原因状语从句，答案应为B(since在此处意为“既然”，而不是“自从”)。
(2)注意before,until,unless等连接词的英语 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )原意与符合中文习惯的表达方式之间的差距。
例2 The American Civil War lasted four years——the North won in the end.
A．after B．before C．when D．then
解析：本题的主句意为“美国内战持续了4年”，从句意为“北方最后取得了胜利”。根据其逻辑，整个句子意为“美国内战持续了4年，北方才最后取得了胜利”，故答案为B(before在此处意为“才”，而不是“在……之前”)。
2．解题时，要分清状语从句与其主句之间 ( http: / / www.21cnjy.com )的关系，正确理解整个句子的逻辑，才能选出正确的答案。
例3 —Did Jack come back ear-ly last night
—Yes.It was not yet eight o'-clock——he arrived home.
A．before B．when C．that D．until
解析：本_题是一段时话。根据“Yes”’的回答，可得知Jack很早就回家了，即“Jack回家的时候还不到8点钟”，答案为B。
例4 You must keep on workingin the evening——you are sure you can finish the task in time.
A．as B．if C．when D．unless
解析：本题前一个句子要求“晚上继续工作”，后一个句子意为“确信能按时完成任务”。按照本题的逻辑，可知句意为“你们晚上必须继续工作．除非你们确信能按时完成任务”，故答案为D。
3．学会区分意思相近的连接词和拼写相似的连 ( http: / / www.21cnjy.com )接词。
在同类状语从句中，有一些连接词的意义和用法很接近。如引导时间状语从句的when/as/while，都有“当……时候”的意思，但在表示“随着”的意思时只能用as，表示“突然”时要用when，表示“正当……”时一定要用while。引导原因状语从句的because/as/since都有“因为”的意思；引导让步状语从句的although/though/as意思都为“虽然，尽管”；no matter/whatev-er/however意思都为“无论，不管”。同学们一定要学会分辨其中的细微差别，否则解题时很容易犯错。
此外，像if和even if, though和as though,as long as和as far 这几组连接词看似相似，实际上其意各不相同，被用来引导不同的状语从句。
例5 Allow children the space tovoice their opinions，——they are dif-ferent form your own.
A．until B．even if C．unless D．as though
解析：本题考查让步状语从句的连接词。根据句子的逻辑，可得知句意为“即使孩子们的观点与你的一样，也要让他们说出来”。even if意为“即使”故答案为B。
例6 He tried his best to solve the problem,——difficult it was.
A．however B．no matter C．whatever D．although
解析：本题提供的四个选项都可以引导状语从名。从句子的语序来看，由于although引导的从句没有倒装现象，可以先排除D。A、B、C三个选 项都有“无论、不管”的意思：however意为“无论怎样”，no matter意为“无论”，whatever意为“无论什么”。整个句子意为“无论问题怎样困难，他还是尽力解决”，故答案为A。

【答案及解析】：
1答案 D
解析 考查状语从句的引导词。so.. ( http: / / www.21cnjy.com ).that...表示“如此……以致……”，引导结果状语从句。句意为：他思考问题太投入了，以致一不留神儿撞到了树上。www-2-1-cnjy-com
2答案 D
解析 在“it＋be＋一段时间＋befo ( http: / / www.21cnjy.com )re/after/since＋从句”句型中，before从句中的动作经过一段时间后才会实现；after从句中的动作发生后已经过去了一段时间；since从句中的动作完成后到现在已经有一段时间了。结合题意可知，答案为D项。
3答案 C
解析 前半句句意为：有人给你打电话，后半句句意为：没有人知道我在这儿。根据句子意思可知前后两句明显为转折关系，因此选C项。
4答案 D
解析 考查状语从句。dress作及 ( http: / / www.21cnjy.com )物动词时，宾语为人；本题中的dress为不及物动词，所以后面应该接一个状语从句。答语句意为：你想怎么穿都行。
5答案 D
解析 句意为：每一次发生火灾，他总是第一个到达现场。every time用作连词，引导时间状语从句。
6答案 B
解析 while并列连词，意为“而，却”，表示转折。
7答案 C
解析 句意为：工程师们都很忙，以致于他们没有时间去做户外运动，即使他们有兴趣。even if即使，符合句意。
8答案 D
解析 考查连词。句意为：如有需要，不要害怕向老师求助。此处when相当于if，表示条件，其他不符合语意。
9答案 C
解析 分析前后分句逻辑关系，是条件或假设关系，而且“祈使句＋and/or/otherwise＋陈述句”是固定句型，所以选C项。
10答案 D
解析 句意为：如果你在一个风俗习惯与你的风俗习惯完全不同的地方旅游，请入乡随俗。此处用where引导地点状语从句。
11答案 D
解析 考查whatever引导的让步状语从句。whatever＝no matter what修饰名词weather。
12答案 C
解析 句意为：约翰篮球打得很好，然而他最喜欢的运动是打羽毛球。四个选项中表示转折的连词只有yet。
13答案 C
解析 考查状语从句。根据语意“我到新华中学的校门口时才知道这学校的准确地址”可知C项正确。
14答案 C
解析 考查状语从句。句意为：如果你没体验过，你不会知道我的感受。unless＝if not如果不，引导条件状语从句。
15答案 D
解析 考查It’s...since ( http: / / www.21cnjy.com )...结构，表示动作自过去发生至今有多久。但该结构从句中谓语动词的性质决定最终的意义。从句中谓语动词为瞬间性动词，则表该瞬间动作发生至今时间多久；若从句中谓语动词为延续性动词，则表示该延续动词动作终止至今时间多久。work属延续性动词，该句句意为：她不在这儿工作已经有两个多月了。显然，本题的答案为D项。
16答案 C
解析 根据句意“无论你有多么 ( http: / / www.21cnjy.com )严重的问题，你都应该鼓起勇气面对挑战。”，而however表让步时其顺序应是：however＋形容词＋主语＋谓语。however作连接副词，相当于no matter how，后接形容词或副词，意为“无论，不管”，引导让步状语从句，其顺序为“however＋形容词、副词＋主语＋谓语”。
17答案 A
解析 前后两个从句都表示地点的含 ( http: / / www.21cnjy.com )义。是定语从句还是地点状语从句，做题的关键是看有没有表示地点的名词作先行词。如果有表示地点的名词，就是定语从句；如果没有便是地点状语从句。该题中第一个从句为地点状语从句，第二个从句为定语从句，因此答案为A项。
18答案 C
解析 考查连词的用法。句意为：尽管没 ( http: / / www.21cnjy.com )有法律规定你怎样穿戴，但是并不是所有的时尚都是值得尊敬的。while尽管，符合句意。because因为；since既然；unless除非。
19答案 B
解析 本句为“祈使句＋and/or＋陈述句”句型。根据题意，应为顺承关系。故选B项。
20答案 D
解析 此处as引导让步状语从句，此时常把作表语的形容词提前到句首。
21答案 D
解析 so long as意思是“只要”，引导条件状语从句。
22答案 A
解析 句意为：明天请安排一次对经理的采访，或者在他方便的任何时间。本句的后半句句子完整，所以应该使用连接副词，结合句意可知应选A项。
23答案 B
解析 when此处为并列连词，相当于at that time，可译为“这时(突然)……”。
24答案 B
解析 空格后的句子是空格前句子的目的，所以用so that。句意为：目标应该现实一点，这样学生们就能实现它，并有成就感。21世纪教育网版权所有
25 答案 B
解析 句意为：他发现读书越来越困难，因为他的视力开始下降。for表示原因，符合句意。
