状语从句大全
状语从句
状语修饰动词、形容词、副词或整个句子。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. To help my disabled aunt , I spend an hour working in her house every day . (不定式)
4. Seen from a distance , the farmhouse looked deserted . (过去分词)
5. I know how to light a camp fire because I had done it before .（原因状语从句）在复合句中修饰主句或主句中的某一成分的从句叫状语从句。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：
A when, while, as, whenever
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。
When I got home, my family were already having dinner.
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）
注意：
当when意思是正当……时候（and at that moment）时，when只能跟在前一分句之后。

他正要上床，忽然门铃响了。

他们刚到家，天就开始下雨了。
②有时when表示虽然，尽管的含义，相当于although或since。

2．while
①while通常表示一段时间，从句中宜用持续性动词作谓语。

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。

提示：虽然during 与while 意思很相近，但是during是介词，不能引导从句。
3．as
①as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。as和when两者经常可以通用。The thief was caught as when he was stealing in the supermarket. 小偷在超市行窃时被逮住了。

①只有当从句表示的是段时间，即其谓语动词有持续性特征时，这三者可以通用互换。
I got the news on the radio when while as I was having breakfast. 我在吃早饭的时候从收音机里获悉这一消息。
②在下列情况下，三者彼此之间不能替换使用：

about my daughter.
她以为我在谈论她女儿，而事实上，我在谈论我的女儿。
d．若表示两个短促动作几乎同时发生时，用as场合多于when。

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。
Though he was hungry, still he would not eat.尽管他饿了，但是他仍然不想吃。
B．Even if, even though
这两个词语气比though, although强，解释即使，两者可以通用。
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。
C．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。
D．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。E．However, whatever, whenever, wherever
这些词在意思上和用法上都等于no matter how what
Whatever happens may happen, we shall never lose hope.无论发生什么，我们都不要失去信心。（有时从句中的动词与may连用）However (=No matter how) expesive it may be, I'll take it.无论它有多贵，我也要买下它。
Don't let them in, whoever (=no matter who) they are.不管他们是谁，别让他们进来。
F．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。提示：
也可直接用or来连接两个相同结构来表示让步。
Walking or sleeping, she always has the question in her mind.无论走路还是睡觉，她总是想着这个问题。G．as
连词as，同though一样，也可以引导让步状语从句，但从句中要用特殊语序。
Young as he is, he knows a lot.他虽然年轻，但懂得很多。(= Though he is young, he.)
Cold as it is, the children play outdoors.虽然天气冷，但孩子们仍在户外玩。
H．if
if 有时也可用于让步状语从句，相当于even if。
If he is poor, he is at least honest尽管他穷，但至少他很诚实。
We'll go if it rains.即使下雨我们也要去。
I'll do it if I die in the attempt.即使会丧命我也要试一下。
注意：
有些时间、地点、条件、方式或让步等状语从句中，如果谓语含有动词be，主语又和主句中的主语一致，或者主语是it，常把从句中的主语和谓语的一部分（特别是动词be）省略掉。
Look out for cars when crossing the street.过街时当心车辆。(= when you are crossing the street)
She hurriedly left the room as though angry.她急匆匆地走出屋去，好象很生气的样子。(= as though if she was were angry)
If possible, I'd like to have two copies of it.可能的话，我想要两本。(= if it is possible,)
She advised me not o say anything unless asked.她劝我别说什么，除非有人要我说。(= unless I was asked )
As a young man, he studied law and became a lawyer.他年轻时就学了法律，并当了律师。
(= As When he was a young man,)

状语从句讲解及练习
状语从句 在复合句中担任状语成分的从句称为状语从句，修饰主句的谓语动词，形容词或副词，状语 说白了就是修饰动作的词或句，也可以理解成修饰谓语的词或句。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. To help my disabled aunt, I spend an hour working in her house every day. (不定式 ) 4. Seen from a distance, the farmhouse looked deserted. (过去分词 ) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 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。 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，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 常用引导词： when, as, while, as soon as, while, before, after, since , till, until 特殊引导词： the minute, the moment, the second, every time, the day ， the instant, immediately , directly, no sooner ? than, hardly ? when, scarcely ? when I didn ’ t realize how special my mother was until I became an adult. While John was watching TV , his wife was cooking. The children ran away from the orchard( 果园 ) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: When I arrived home , I had a little rest. 注意点： when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be 可以省略。Eg: When (she was) walking along the street, she met her class teacher. 2) As As 除了表示“当```的时候”，还可表示为“一面``` 一面”，“随着” Eg: He sang as he danced.(一面 ```一面 ) You will grow wiser as you grow older.(随着) 3) While 表示“当 ``` 的时候” 强调主句的动作和从句的动作同时发生，从句一般用进行时， 从句动词必须是延续性动词。 Eg: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1．until, not ? until 表示“直到 ```才” ,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
as引导的五种状语从句
as作从属连词用时,可以引导五种状语从句。现归纳如下： 1. as表示“当……的时候”,引导时间状语从句,多强调主句和从句中的动作或状态同时发生,从句可放在主句前,也可放在主句后。例如： As I waited at the stop, I heard a big noise. 当我在车站等车的时候,我听到一个很大的声响。 She rose up as he entered. 当他进来时,她站了起来。 2. as表示“因为”、“由于”,引导原因状语从句,其语气不如because强,通常为附加说明的理由,且是已知晓的原因,主句与从句没有逻辑上的因果关系。例如： As she was not well, I went there alone. 因为她身体不好,所以我独自到那里去了。 As he is a tailor, he knows what to do with this material. 由于他是个裁缝,他知道怎样利用这块布料。 3. as表示“虽然……但是……”,引导让步状语从句,从句通常用倒装语序,把从句的表语、状语或动词原形放在as前面,可以用though替代。例如： Child as he is, he knows a lot. 虽然他是个孩子,但他知道的东西很多。 Hard as it was raining, they went on working in the field. 虽然天下大雨,但他们继续在田地里干活。 4. as表示“按照”、“依照”、“像”,引导方式状语从句,从句置于主句之后。例如： You should do as the teacher tells you.你应当依照老师所说的去做。 The absence of air also explains why the stars do not seem to twinkle in space as they do from the earth. 空气的不存在,也说明了为什么在空中星星看来并不闪烁,而不像从地球上看的那样。 5. as表示“像……一样”,引导比较状语从句,对主句和从句的动作或状态加以比较,说明它们之间有相似之处,在从句中常省略与主句相同的部分。例如： He doesn't work as hard as I (do). 他不像我工作那样努力。 I hope the necklace was as good as the one you lent me.我希望我挂项链同你借给我的一样好。

状语及状语从句解析
状语(adverbial)是句子的重要修饰成分。状语是谓语里的另一个附加成分，它附加在谓语中心语的前面，从情况、时间、处所、方式、条件、对象、肯定、否定、范围和程度等方面对谓语中心进行修饰或限制。在英语中，状语修饰动词、形容词、副词等的句子成分。 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。 1.副词一般在句子中做状语. He speaks English very well. 他英语说得非常好.中的very是程度副词，用来修饰well。very well是修饰speak的程度状语。 2.不定式在句子中可以作目的状语。 I come specially to see you. 我专门来看你. 3.介词短语 Ten years ago, She bega n to live in Dalia n. 十年前，她开始住在大连。 The boy was praised for his bravery. 4.从句作状语 When she was 12 years old, she bega n to live in Dalia n. If I am not busy tomorrow, I will play football with you. 5.分词作状语 Havi ng had a quarrel with his wife, he left home in a bad temper 。 In hibited in one direct ion, it now seems that the Mississippi is about to take ano ther. 状语简介 概述 状语与定语相同的地方是，都是前者附加成分；不同的地方是，它是谓语里的附加成分，而定语是主语或宾语里的附加成分.从句子的层次上看，状语是在第二个层次和第三个层次里的成分，有时甚至是更低层次的成分.
状语从句讲解及习题附答案
（一）状语从句概述 定义状语从句用作状语，是起副词作用的句子。 位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。 分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。 作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。 （二）状语从句详解 1. 时间状语从句 引导词用法示例 when 意为“当…的时候”。When 引导从句的谓语动词可以 是延续性动词，也可以是 瞬间动词。并且when有 时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。When he arrives, I’ll call you. When you laugh and smile, your body relaxes. while 意为“在…的时候，在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.
的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的， 发生时间较短，一般用于 主句和从句动作同时发 生；as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语， 并且当before引导的从句 位于主句之后，有时译成 “就，才”。当主句用将来时，You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada

状语从句 状语从句修饰主句/主句的谓语。一般有九大类：表示时间、地点、原因、目的、结果、条件、让步、比较和方式等。 时间状语从句 1. 用when引导：when表示“当……时候”。如： Things were different when I was a child. 我小时候情况与现在不同。 People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢。 2. 用while引导：while表示“当……时候”。如： We must strike while the iron is hot. 我们要趁热打铁。 I went swimming while the others played tennis. 我去游泳，其余的人都打网球去了。 注意：while 所引导的时间状语从句中谓语动词必须是持续性的，不能是短暂性的。 3. 用as引导：as表示“当……时候”“随着”。如： He dropped the glass as he stood up. 他站起来时，把杯子摔了。 We get wiser as we get old. 随着年岁的增长，我们也变得聪明些了。 4. 用before引导：before表示“在……之前”。如： Turn off the lights before you go to bed. 睡觉前要关灯。 Before he went to university he was a worker. 上大学之前他是工人。 5. 用after引导：after表示“在……之后”。如： I will tell you after they leave. 他们走我再告诉你。 After you finish the letter show it to me．信写完后给我看看。 6. 用until / till引导：until / till表示“直到……”。如： He waited until she was about to leave. 他等着一直到她准备离开。 I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失。 这类句型的主句动词通常只能是延续性动词，不能是终止性动词。但是，在否定句中，主句动词可以是终止性动词，此时构成not…ntil [till]…句式，意为“直到……才……”。如：

【优质】第14讲 长难句状语从句的翻译上
第十四讲长难句状语从句的翻译（上） 今天这一讲及下一讲，我们讲状语及状语从句的翻译问题。 由于状语的翻译问题很有系统性，而且篇幅较大，而状语从句的内容又较多，我想，还是作为单独一讲先讲解状语的翻译问题。本讲回顾状语的若干问题。希望为后面的内容打好基础。 与定语一样，状语也包括词汇状语、短语状语、从句状语等等。 1. 词汇状语 词汇状语比较简单，只有副词是唯一作状语的单词。 1.1 当其修饰整个句子时一般置于句首，汉译时相同。如： Usually, the more crowded the conditions of living, the higher is the attack rate. 一般说来，居住得越拥挤，发生率也就越高。 1.2 当修饰形容词或副词，或者其他词组句子时一般置于被修饰成分前，汉译相同。如： The mistake was made entirely through a misdiagnosis. 错误完全是由于一次误诊所致。 1.3 英语中，表示频率的副词，如frequently，often，usually，always，等等，修饰动词时，一般置于实义动词（如predispose，诱发）前，连系动词或助动词be后，不过不同的是，汉译时需要前置。 Influenza frequently predisposes to highly fatal secondary infections of the lungs. 流感常常容易诱发死亡率很高的肺部继发性感染。
1.4 修饰及物动词时往往置于宾语后，不过若该副词为频率副词，则不论动词及物不及物，都置于动词前或助动词后，汉译时前置。 Its wear characteristics far exceed those of all currently employed ball occluders. 其耐磨性远远超过所有当前所采用的球形闭合器。 2. 短语状语 介词短语、不定式短语、分词短语、形容词短语、名词短语等，都可以充当状语。而短语状语在句中不同的位置，在翻译中就需要不同的处理。下面分类讨论之。 2.1 短语状语谓语句首 我们在翻译中可以看到很多位于句首的短语状语，有的很长，在翻译中需要应维持原状不变。如： In a given patient the choice of antihistaminic drug depends upon trial and error and a decision whether sedation is desired or not. 在特定的病人中，选用何种抗组胺药物，要用视差法，并需要取决于是否需要镇静疗法。 2.2 短语状语作为插入语位于句中或句末 在汉译时如果不至于造成句子各个部分的失衡，我们一般还是放在句首较好。如果还是按照原语序的话，那将是非常复杂的。 Dust from floor, from the practical point of view, is probably a negligible source of airborne infection in operating rooms. 从适用的观点来看，地板上的灰尘或许是一种可被忽视的手术室内空气感染的来源。 2.3 句中较长的短语状语 如果句中的短语状语很长的话，我们一般还是不会在翻译中继续放在中间，而且放在句首或者句末。 The bacteria show on all the common culture media under aerobic conditions a
