高中英语 状语从句精讲及专项练习(有答案)
状语从句
新课讲解
知识点1）状语与状语从句
状语（adverbial)
状语（adverbial)的定义：英语中,修饰动词、形容词、副词等的句子成分叫状语（adverbial)。
状语的功用：状语说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等。状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。其位置一般放在句末，但也可放在句首或句中。
副词是一种用来修饰动词,形容词,副词或全句的词,说明时间,地点,程度,方式等概念。请判断状语部分。
1.Naturally, our grandparents were pleased to get our phone call. ( )
2.We worked hard, from sunrise to sunset. ( )
3.Seen from a distance, the farmhouse looked deserted. ( )
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。
状语从句（Adverbial Clause）
根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。
解题要领：了解各类状语从句典型连词的基本意思，弄清主从句之间的逻辑关系，代入题干进行校对。
状语从句在句中作状语，修饰主句中的动词，形容词或副词等。状语从句放在主句之前时，常用逗号分开；放在主句之后，一般不用逗号，状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等9种。
引导状语从句的连词分类
1.时间和条件状语从句讲求“主将从现”的时态规则，但要注意whether一词。
?Whether it rains (rain) or not, I shall go out for an outing tomorrow.
?Can you tell me whether it will rain (rain) tomorrow?
?Whether it will do (do) us more harm than good remains to be seen.
当whether作“无论”解，用现在时表将来。但当whether作“是否”解时则不能用现在时表将来。
2.注意下列连词的基本释义
as soon as / the moment / directly一……就……
no sooner…than / hardly…when刚……就……
since / now that / seeing that既然
in that因为；由于
provided / on condition that / suppose (ing)如果
once一旦
as/so long as只要
in case以防；万一
given that考虑到……
seeing that鉴于
even if即便
even though尽管
as if / though好象
unless除非，如果不
wh-疑问词+ ever / no matter + wh-疑问词无论……不管……
until到……为止
not…until直到……才
as/ so far as就……而言
as far as…远至
so that 为了……
so/such…that太……以至于……
知识点2）：状语从句的分类
时间状语从句
时间状语从句的时态一致
（1）如果主句是一般将来时，在时间状语从句中用一般现在时表将来。
（2）如果主句是一般将来时，若时间状语从句强调动作完成，从句也可以用现在完成时。
1、while, as, when/whenever的用法比较
连接词when的用法小结
when(特指)引导的从句表示的具体的时间，从句的动作和主句的动作可以同时，也可以先于主句的动作。whenever（泛指）指任何一个不具体的时间。
（1）when引导的时间状语从句的谓语动词可以是可延续的，也可以是表短暂性动作的动词，可用于主句和从句动作同时发生或从句动作先于主句动作。如：
When the film ended, the people went back.
When I lived there, I used to go to the seashore on Sundays.
（2）可用作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式：
Somebody was doing something/was about to do sth./was on the point of doing sth. when… (刚要……这时突然……)
（3）还可以表示原因“既然”，相当于since; considering that。如：
It was foolish of you to take a taxi when you could easily walk there in five minutes.
（4）When的意思
1) 当…时候
2）那时；这时（突然）
be doing…when
be about to do …when
be on the point of doing …when
had just done…when
3）既然（原因状语从句）
It was foolish of you to take a taxi when you could easily walk there in five minutes.
连接词while的用法小结
（1）while引导的动作必须是持续性的，侧重主句动作和从句动作相对比。如：
Please don’t talk so loud while others are working.
（2）while作为并列连词，意为“而，却”，表示对比。
There's plenty of rain in the southeast, while there's little in the northeast.
Some people waste food while others haven't enough.
★注意:while与but的区别
二者都有“而,然而”之意,但while强调二者的对比,而but强调前后的转折关系。
（3）while可表示尽管，相当于although。
连接词when, while, as的用法区别：
（1）While指一段时间。表示主句和从句的动作同时发生，并持续一段时间。从句的谓语动词必须是可延续的。
When指一点时间或一段时间。表示主句和从句的动作同时发生，也常表示从句动作先于主句动作。引导的从句的谓语动词是可延续的，也可以是表短暂性动作的动词。如：
When/While he was eating his breakfast, he heard the doorbell ring.
When I stopped my car, a man came up to me. (不可用while)
When you have finished your work, you may have a rest. (不可用while)
（2）as指一点时间，以可指一段时间。侧重于表示在从句动作发生过程中主句动作同时发生。
当主句和从句的主语一致时，as还有“一边…一边…”的意思。
As I was getting on the bus, someone called me.
As he walked along, he sang happily.
As the election approached, the violence got worse. (表示“随着……”，连词用as，不用when 或while)
（3）如果主句表示的是短暂动作，而从句用延续性动作的进行时态表示在一段时间内正在进行的动作时，when, while 与as 可互换使用。如：
When/While/As I was walking down the street, I came across an old friend of mine.
2、名词词组引导时间状语从句
有时名词every time(每次)，the next time(下一次)，by the time, the next day(第二天)，the first time，every day, the year…等，也可起从属连词的作用，引导时间状语从句。
I thought her nice and honest the first time I met her.
Every time you get back at night, you drop your shoes on the floor.
I didn't have a penny the last time I saw you.
3、表示“一…就”的连词或词组
as soon as
the moment, the minute, the second, the instant…
instantly, immediately，directly, presently…
hardly/scarcely…when, no sooner…than….
I'll give you a phone as soon as I come back.
—Did you remember to give Mary the money you owed her？你记着还给玛丽的欠款了吗？
—Yes．I gave it to her the moment I saw her．是的。我一见到她就还给她了。
The young lady rushed into the room immediately she heard the noise.那位年轻女士一听到响声就冲进房间。
Directly the master came in, everyone was quiet.校长一进来，大家就安静下来。
Hardly had he arrived when she started complaining.他刚一到, 她就开始抱怨起来。
4、since和before的用法比较
两者均可用于“It+ be...+since/before-从句”的句型。区别在于since表示“自从……以来”，
所在主、从句的谓语动词的时态关系是:
It is/has been sometime since sb. did sth.。
It is/has been 30 years since he joined the revolution. 他参加革命己三十年了。
before主、从句的时态关系是:
It was some time before sb. did sth.过了多久才……和It will be some time before sb. does sth.还要过多久才……
It was three days before he came back. 他三天后才回来。
It will be three days before he comes back. 他三天后才会回来。
否定句型It be not ＋一段时间＋ before 肯定句“不多久就……”
It was not long before he came back. 不久他就回来了。
It wasn’t two years before he left the country. 没到两年他就离开这个国家了。
比较记忆：before long不久以后
long before 很久以前
They came back before long.他们很快就回来了。
I knew Tom long before I knew you. 我在认识你之前很久就认识了汤姆。
5、till/until，not…until
①till/unitl主句谓语动词必须是延续性动词, until=till，但是在句首只能用until
not…until主句的谓语动词经常是非延续性动词，也可以是延续性动词
They stayed there until we came back.
They didn’t leave until we came back.
②It was not until…that…强调从句时需把not放在从句前面
It was not until a Saturday afternoon in May that he could arrange for me to meet her elder sister.
③not until在句首时，主句要部分倒装
Not until all the fish died in the river did the villagers realize how serious the pollution was.直到河里的鱼都死了村民们才意识到污染的严重性。
6、once 一旦
Once I arrive in Shanghai, I will call you.

DABC
第2题答案A
解析：
while引导的句子中的谓语动词为延续性动词或状态性动词；
when引导的句子中的谓语动词可为延续性或非延续性动词．bite为非延续性动词，when在此处为并列连词，意为“这时
第3题答案B
分析：解此题的关键在于主句与从句在时态上保持一致。用A、C、D三项的连接词引导时间状语从句时，与主句的时态明显不一致。since引导从句时常用过去时，主句则用一般现在时或现在完成时。
地点状语从句
地点状语从句一般由where，wherever和everywhere引导。
After the war, a new school building was put up where there had once been a theatre. 战后，一所新学校在以前的剧院处建成。

第1题：B
题意：今天，我们将从昨天停下的地方开始这样就不会有知识点被漏掉了。
where 引导宾语从句，在宾语从句中作状语，因为宾语从句中stopped是不及物动词，不能
带宾语。
第2题：B
第3题：C
原因状语从句
原因状语从句一般由because(因为)，since(既然)，now that(既然，因为)，as(由于)等连词引导
1、because, since, now that和as引导原因状语从句

2、so…that与such…that的区别
这两种结构都可引导结果状语从句。so是副词，后接形容词或副词；such是形容词，后接名词。
（1）单数名词
在so...that与such...that中间出现的是单数名词，且该名词前有形容词修饰时，这两种结构可互换，但要注意它们的词序不同:such+ a/an+形容词十名词=so+形容词+a/an+名词。

让步状语从句
让步状语从句由though，although，as，even if (though)，however，whatever，whoever，whenever，no matter +wh词，等引导。
1、even if, even though, although，though, while引导的让步状语从句
这四个词（词组）都有“虽然、即使、尽管”的意思。even if和even though带有较强的意味，语气比although和though强。though比although通俗，但不如although正式,都不能和but连用，但可以和yet, still或nevertheless连用。可以放在主句前面也可以放在主句后面。even if，even though所接的句子常用虚拟语气。

Fail as he did, he would never give up.尽管他失败了，但他决不会放弃。
总结：倒装是把表语提前；没有表语时，将状语提前；没有状语时，将部分谓语提前
3、由no matter+ wh词和由疑问词＋ever引导让步状语从句
由no matter引导，表示“不管；无论”；由疑问词＋ever引导，表示“不管，不论”。这类词有：whatever，whichever，whoever，however，whenever，wherever等,他们相当于no matter+ what（which，who，how，when，where），都不能与but，so，and等并列连词同时使用。
We'll have to finish the job, however(no matter how) long it takes.
No matter what(Whatever) you do, don't tell him that I told you this.

虽然“ no matter ＋疑问词”和“疑问词＋ever ”都可以用来引导让步状语从句，但后者的用途更广，这类词还可用来引导主语从句、宾语从句、时间或地点状语从句等。例如：
Whoever comes to the party will receive a gift.（主语从句）
比较：Whoever comes to the party, he will receive a gift. （让步状语从句）
＝No matter who comes to the party，he will receive a gift.

由whether．．．or引导让步状语从句表示“不论……还是”，提供两种对比的情况。
I shall go, whether you come with me or stay at home. 不论你和我一起来还是留在家中，我都要前往。
Whether we like a particular piece of news or not, all we have to do is sit in front of the tube and “let it happen”.不管我们喜欢不喜欢一条消息,我们所能做的只是坐在电视机前，“让它过去”。

方式状语从句一般由as(正如；按照)，as if/as though(好像)等引导。

You must do everything as I do.你们要照我这样去做。
Just as the water is the most important of liquids, air is the most important gases.正如水是液体中最重要的一种一样，空气是气体中最重要的一种。

知识点3）状语从句的时态问题
在条件，时间和让步从句中，用一般现在时表示一般将来时，用现在完成时表将来完成时，用一般过去时表过去将来时。在since 引导的时间状语从句中，动词一般都用一般过去时，而主句常用现在完成时。
如：I will return the book after I have finished reading it.
Tom said he would go to Beijing when he graduated from the university.
知识点4）状语从句主谓成分的省略
状语从句主谓成分的省略是英语语言在使用过程中出现的一种较普遍的语法现象，它能使语言言简意赅。
Though understanding no Chinese, the American girl was able to communicate with the other students in her class.
When asking the teacher, he was very polite.
Until finished, the problem was a continuous worry to me.
He’ll go to the seaside for his holiday if (it is) possible.
I. 状语从句主谓成分的省略，须遵循下面原则：
（一）当从句的主语与主句的主语一致时，从句可以省略主语，从句的谓语动词采用其V-ing 结构。例如：
Although working very hard, he failed in the final exam. (Although he worked very hard,…)
After taking the medicine, she felt much better. (After she took the medicine,…)
If going there by air, we’ll have to pay twice the fare. (If we go there by air,…)
（二）当从句的主语和主句的主语一致时，若从句的谓语动词是系动词be或包含be的某种形式，此时从句的主语和be动词通常可以一同省略。常见于以下几种形式:
1、连词+形容词
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。
She hurried out of the room, as if (she was) angry.
2、连词+名词

(完整word版)高中英语状语从句用法详细解析
高中英语状语从句用法详细解析 一、定义： 在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。 二、分类 根据意义上的不同，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句 三、时间状语从句 （一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once. （二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。
英语让步状语从句用法总结
英语让步状语从句用法总结（一） 让步状语从句的用法一（表示“虽然，即使，尽管”） 1. although，though，even though，even if都表示“虽然，即使，尽管”之意，though 和although 语气较弱(其中的though 比although 通俗, 不如although 正式)，even if和even though 带有强调意味而显得语气更强。例如：Although they are poor, they are happy. 虽然他们很穷，但很快乐。天气虽然很冷, 但他没有穿大衣就出去了。即使他们可能不会成功，但他们仍努力尝试。那篇文章虽然很短，但很重要。他好一点了，虽仍未痊愈。即使下雨，她也是走着去工作的。今晚我将去拜访他，即使我只能停留一小会儿。 注意：though 引导的让步状语从句的用法比较特殊，它可以倒装，也可以不倒装，具体用法参见as引导让步状语从句的用法。 2. as引导让步状语从句表示“虽然、即使、尽管”，其引导的让步状语从句必须采用倒装结构，as引导的倒装形式的让步状语从句的基本结构为：形容词/副词/名词(单数可数名词前一般不带冠词，有时也可见单数可数名词前形容词与不定冠词连用、形容词放在不定冠词前)/动词/过去分词＋as＋主语＋谓语的其他部分。注意体会下列典型例句：Great as the author was, he proved a bad model. 这位作者尽管了不起，到头来却成了一个坏榜样。这个故事看似荒唐，却是真的。虽然他很富有，但他并不幸福。倒装时要省去单个名词前的冠词)尽管还是个孩子，他却能分辨黑白。他尽管勇敢，可见到蛇还是发抖。尽管伤势很重，他仍然十分乐观。虽然尽了最大努力，但是他仍然不能搬动那块石头。 ［考题1］We had to wait half an hour ____ we had already booked a table. A. since B. although C. until D. before ［答案］B ［解析］下划线处之后所述的“我们已经预订了一桌”与前面所述的“我们已经不得不等了半个小时”之间语意相反，四个选项中although表示“即便……”，引导让步状语从句最为合适。 ［考题2］____ most of the earth’s surface is covered by water, fresh water is very rare and precious. A. As B. Once C. If D. Although ［答案］D ［解析］句意为：虽然地球表面覆盖着水，但是纯净水仍然很稀有、珍贵。下划线处应引导让步状语从句，填入although最为合适。 ［考题3］____ he has limited technical knowledge, the old worker has a lot of experience. A. Since B. Unless C. As D. Although ［答案］D ［解析］下划线处应引导让步状语从句，填入although最为合适。 ［考题4］Although he is considered a great writer, ____. A. his works are not widely read B. but his works are not widely read C. however his works are not widely read D. still his works are not widely read ［答案］A ［解析］英语不允许在连词although、though引导的让步状语从句之后的主句句首重复使用连词，如果要在复合句中强调某种特别的意义，可以在主句的句首加上yet、still等副词。例如：Although she has a lot of money, (yet/still) she is not happy. 虽然她很有钱，但是她并不快乐。

As引导让步状语从句倒装的用法
As引导让步状语从句倒装的用法 为了帮助同学们全面掌握让步状语从句的倒装用法，本文将这类语法现象归纳为以下五种句型： 一、名词+ as / though + 主语+ 动词 King as he was，he was unhappy. 他虽是国王，但他并不幸福。 Child as he is，he knows to help other. 他虽是个孩子，却知道帮助别人。 【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语。另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。比较： Boy as ［though］he is，he likes to play with girls.=Though he is a boy，he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩。 Strong man as ［though］he is，General Botha has been severely put to the test during the past few weeks.= Though he is a strong man，General Botha has been severely put to the test during the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验。 二、形容词+ as / though + 主语+ 动词 Successful as he is，he is not proud. 他虽然成功，但不骄傲。 Improbable as it seems，it’s true. 虽然看起来不太可能，但却是真的。 Stupid as it sounds，I was so in love with her that I believed her. 尽管听起来很愚蠢，我是如此爱她竟然相信了她的话。 Patient as he was，he didn’t like waiting that long. 他虽说有耐心，也不愿等这么长。 Beautiful though the necklace was，we thought it was over-priced. 那条项链虽然很漂亮，我们认为价钱太高。 【说明】其中的动词也通常为连系动词，也就是说位于句首的形容词是其后连系动词的表语。 三、副词+ as / though + 主语+ 动词 Much as I like Paris，I couldn’t live there. 尽管我喜欢巴黎，但我不能住在那里。 Hard though they tried，they couldn’t make her change her mind. 尽管他们做了很大努力，却没法让她改变主意。 Fast as you read，you can’t finish the book in two days. 尽管你读得很快，你总不能在两天之内就读完这本书。 He was unable to make much progress，hard as he tried. 尽管他做了努力，却未能取得很大进步。 【说明】有的词典将much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词。再如： Much as I admire him as a writer，I do not like him as a man. 他作为一名作家我很佩服他，但我却不喜欢他这个人。 Much as I like you，I couldn’t live with you. 我尽管很喜欢你，却不能和你在一起生活。 四、动词原形+ as / though + 主语+ 动词 Object as you may，I’ll go.纵使你反对，我也要去。
高中英语状语从句讲解
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3.

She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句
