状语从句在复合句中作状语的从句叫状语从句。状语从句有时间、地点、原因、目的、结果、条件、方式、比拟、让步等种类。一、时间状语从句引导时间状语从句的连接词有: when, as, while, after, before, since, ever since, as soon as, once, till, until, whenever, no soonerthan, hardly/scarcely.when, the moment/minute/instant/second, every time, each time, any time, the first time, next time, last time, all the time, by the time, directly, immediately, instantly等。“一就的句型1) as soon as/onceAs soon as he arrives, Ill call you.他一到，我就给你打。as soon as 侧重时间或动作先后衔接紧，而once侧重条件，表示“一旦.On arriving at the station, the thief was arrested.一到达车站，这个小偷就被逮捕了。 On his arrival in Paris, he was recognized as a noble and thrown into prison. 他一到达巴黎，就被认出是一个贵族，并被投入监狱。3) no sooner .than , hardly/scarcely.when 它们表“一就。结构中的否认词放在句首时，主句要倒装。主句都用过去完成时，从句用一般过去时。 No sooner had he reached home than it began to rain.他刚到家，天就开始下雨了。 Hardly/Scarcely had I entered the room when the phone rang.我一进屋，就响了。注意当no sooner, hardly, scarcely不放在句首时，主句不倒装，如：I had no sooner reached the bus stop than the bus started.我刚到车站，车就开走了。 I had scarcelyhardlyentered the room when the phone rang.4the moment, the instant, the minute, the secondThe moment I saw him, I recognized him.我一看见他，就认出了他。 Well leave the minute you are ready.你一准备好，我们就出发。5)有些副词如：instantly, immediately, directly可用作连词，后接从句。I left immediately the clock struck 5.我刚走，钟就敲了五点。2. when, while, as引导时间状语从句1) when的用法when既可指时间点，也可指时间段即：从句动词可以是短暂的也可是延续的；主从句动作可同时也可先后发生。I was thin when I was a child. 当我是个孩子的时候,我很瘦。 It was raining when I arrived.我到达时，天正在下雨。在when引导时间状语从句时，如果从句主语与主句主语一样或为it，且从句有be动词，如此从句可省主语和be动词，如：When (you are) in trouble, you can visit this man.当你有麻烦时，可以找这个人。 She is always listening to music whenshe is) doing her homework. 当她做作业时，总是听音乐。when在如下结构中, 译成“这时,它引导的是并列句be about to do . when, be doing . when, had done when,be on ones way . when, be on the point of doing . when参见“连词局部when的用法2while用法while只能指一段时间，从句中的动词必须是延续性动词。强调某一段时间发生主句动作，相当于during the time that.My mother was cooking while I was doing my homework.当我在做作业时，妈妈在做饭。 I am safe while I am here.我在这儿的时候，我很安全。注意 while除引导时间状语从句外，还引导比照句，作“然而讲；并可在句首引出让步状语从句作“虽然但讲。I like watching TV, while he likes reading.我喜欢看电视，而他喜欢读书。 While he has his own car, he often uses mine.尽管他自己有车，他却常用我的。3) as的用法 as引导时间状语从句时常可和when换用，但较强调同时发生，多指短暂动作。As I left the house, I forgot the key.我离家时，忘了带钥匙。 as还可说明两种正在开展或变化的情况，“随着.的意思，表时间的推移。如：As I get older, I get more optimistic.随着年龄的增长，我变得更加乐观。as表“一边一边，引出伴随动作。He hurried home, looking behind as he went.他匆忙地回家，边走边往后看。用以强调两个动作紧接着发生。As he was going out, it began to rain.当他出去的时候，天开始下雨了。as有时引出一个名词，相当于一个时间状语从句。As a boy (when he was a boy), he was hopeless at maths.当他是孩子时，他对数学失去希望。3. before引导的时间状语从句before引导的时间状语从句不用否认式谓语。Before they got to the bus stop, the bus had gone.在他们到达公共汽车站之前，公共汽车已经走了。在“It be + 时间段 + before从句句型中，肯定句译成“之后才，否认句译成“就。该句型有一般过去时、过去将来时、一般将来时三个时态，且有否认句。It will be some time before. do.It was some time before.did.It would be some time before.did.It was long before.did.“很久才It wasnt long before.did.“不久就.It will be many years before the chemicals start to escape fromthe containers. 多年以后化学物质才开始从容器中逃逸。It was not long before he came back.不久他就回来了。It was a long time before he got to sleep again.很久他才再次入睡。It was a week before he could tell his story.一个星期后他才能讲述他的经历。 It wasnt long before he told us about himself.不久他就给我们讲述了他自己的故事。before可译成“未来得与He had measured me before I could get a word.我还未来得与插话，他就量好了尺寸。before可译成“趁着还没Ill write it down before I forget.趁着还没忘我要把它写下来。4. until和till 1)“延续性动词肯定式+until表示“动作延续到为止，译为“直到为止，如：I waited for him until he came back. 我一直等到他回来。2)“终止性动词的否认式+ until表示“直到才。He didnt go to bed until he had finished his work. 直到完成工作他才睡觉。3)用于强调句式“It is not until .that .It was not until the professor came that we began the experiment.在教授到来之后，我们才开始实验。4) not until放在句首时，主句倒装。Not until he graduated did he succeed in obtaining this pound. 直到他毕业他才成功获得这种化合物。注意句首和强调句中要用until，而不用till；not.until.句型中不用till。5. since引导时间状语从句，意为“自从时起，主句要用完成时。Mr. Li has been here since he came back.自从先生回来以后，他一直在这儿。I havent heard from him since he lived here.自从他住在这儿以来，我就没有收到过他的来信。Ive known Mr. Smith since I was a boy.我小的时候就认识史密斯先生了。当时间状语从句的主语和主句主语一样或为it，从句又含be动词时，从句可省略主语和be动词。在不产生歧义时，连词也可省去。如：Once (it is) seen, it can never be forgotten.一旦被看见过，永远也不会被忘记。二、地点状语从句1.地点状语从句主要由where, wherever anywhere, everywhere引导。We must camp where we can get water.我们必须在能找到水的地方露营。 I will follow you wherever you go.无论你到何处我都要跟随你。2.地点状语从句与定语从句的区别：where引导定语从句，从句前应有一个表示地点的名词作先行词。Go back where you came from.where引导地点状语从句 Go back to the village where you came from.where引导定语从句，village为先行词三、原因状语从句原因状语从句由because, as , since, now (that)既然, in that因为，多于口语中,seeing (that)鉴于，由于,considering that考虑到等引导。1. because用来回答why提出的问题，表直接的因果关系，用于告知对方不知道的原因，语气最强，可用于强调句。 He didnt attend the meeting because he was ill.他没参加会议，因为他病了。 It was because he was ill that he didnt go with us.因为他有病，他没有和我们一起去。注意 because和because of的区别：because是连词，引导从句，because of是短语介词，后接名词性词语，如：The football match was put off because it rained. The football match was put off because of the rain.因为下雨，足球赛延期了。2. since, as, now that引导的原因状语从句，不能用于强调句。since的语气比because稍弱，表示关系上的自然结果，特别用于原因已经清楚了的事情，一般译成“既然，鉴于往往放在主句之前如：Since you have known the secret, I neednt say anything about it. 既然你已经知道了这个秘密，我就不必说了。as语气最弱，说明一般的因果关系，表显而易见的原因或倒果为因的说法可放在主句之前，亦可放在主句之后，如： As he didnt know much English, he got out his dictionary and looked up the word “cough.他对英语懂得不多，他拿出字典查找“cough这个词。 As the ground is wet, it must have rained last night.倒果为因昨晚一定下了雨，地面是湿的。 now that用来说明一种新情况，然后加以推论。now that放句首时that可省略： Now (that) everybody is here, lets begin.3. for也可以表示原因，属并列连词，不是说明直接原因，而是对某种情况加以推断，表示补充说明理由。而推断的理由会因人而异。语气很弱，它引出的分句必须放在另一分句后。 He must be ill, for he is absent today.4.原因状语从句有时可以用分词形式表现。 As he was blind, he couldnt see anything. Being blind, he couldnt see anything.四、条件状语从句1由if, unlessif.not, so/as long as, supposing(that)假设, in case万一, 以防, so/as far as就.而言, on condition that条件是., provided/providing (that)假假如引导。Tell me about it if you have time.I wont go unless Im invited.Take an umbrella with you in case it rains.You may use the room as/so long as you clean it up afterwards.2.“祈使句+and/or/or else/otherwise+述句的句型中，祈使句在意义上实际上相当于条件状语从句。 Use your head, and youll find a way. Hurry up or else (otherwise) youll be late.3. if only也可以引导条件状语从句,只不过较少使用而已。only if也引导条件状语从句，意思是“只有在.条件下 If (only) it clears up, I will go.4.条件状语从句中一般要用一般现在时态表将来。 I will go if you go.1)从句主语为it,又有系动词be时，可以省略从句中主语和be动词。 e tomorrow if (it is) possible. If so, you must get back and get it.还有诸如if necessary“如果有必要，if any“如果有，if in need“假如需要。2如果if从句的主语和主句的主语一致，谓语动词又有be,可以把从句中的主语和be省略掉。 If (water is) heated, water sends out steam. if引导的条件状语从句假如与过去或现在事实不符，或对未来进展不可能的假设，就要用虚拟语气。详见虚拟语气局部省略if的虚拟条件从句：假如条件从句的谓语动词有were, had或should,可以把if省去，而把were，had或should移到主语前构成倒装。Had I arrived there earlier, I would have seen him. Were it not for him, I would not have the chance to go home. Should he be here tomorrow, I would give him a hand.五、目的状语从句由so that以便， in order that为了，for fear that= in case以免，lest以防引导，谓语常含may, might, can, could, will, would等情态动词。They set out early so that they might arrive at the station in good time.Ill speak slowly so that/in order that you can understand.He wrote the name down for fear thatlesthe would forget.当从句与主句主语一致时，可用to do, so as to do, in order to do结构换用。 He worked day and night in order that he could succeed. He worked day and night in order to succeed.六、结果状语从句1.常用的连词有so that，so . that, such.that, that带古英语痕迹。结果状语从句中一般无情态动词 He had overslept so that he was late for work. My pen fell under my desk that I couldnt see it.2. so/such .that所用句式so + adjadv) + that从句 The box is so heavy that I cant carry it.so+adj +a/an+单名+ that从句such a/an+adj.+单名+that从句 She is so beautiful a girl that all the boys of our class like her. =She is such a beautiful girl that all the boys of our class like her.so many/few +复名+ that从句 so much/little+不可数名词+ that从句There are so many apples on the desk that we each have one. There is so little water that you cant drink.such +a/an + adj + 单名+ that从句 She is such a good girl that she can help you.such + adj +复名/不可数名+ that从句 It was such bad weather that we all stayed home. He has such interesting books that he keeps reading all day.注意 little表“小，可爱时，用such不用so修饰。 He is such a little boy that his patents often teach him something.七、方式状语从句由as, as if (as though)引导。 Do as you like. He spoke as if he had been there before.注意 as if, as though从句与事实相反时用虚拟语气，与事实相符，不用虚拟语气。八、比拟状语从句常用连词than, as .as., not as/so. asHe ran as far as he could.Im not as/so tall as he/him.She studies harder than Istudythe more . the more.引导, 且经常以省略形式出现 The harder you try, the better you will understand.九、让步状语从句由though, although, as, even if/though , no matter wh-, wh-ever词，whether.or不管.都，when, while等引导。1. though, although这两个连词用法根本一样，只是前者口语化，后者较正式，常位于句首，都不与but连用，但可以和yet，still，nevertheless连用。though还可作副词单独放在句尾，表示“然而的意思。 Although the TV set is very dear, I still want to buy it. Though /Although he was worn out, he kept on working.2. as引导让步状语时，从句局部用倒装语序，句型为:形容词/副词/名词+ as +主 +谓动词+ as +主 +情态动词Child as he is, he knows a lot.Proud as these nobles are, they are afraid to see me.Great a scientist as he is, he remains modest.Try as I might, I couldnt lift the stone.注意在这种倒装结构中，也可以用though不太常用，但不可用although. Bravely though the players fought, they had no chance of winning.3. even if尽管；即使, even though尽管这两个复合连词意义根本一样，常用以强调让步概念，有退一步想的意思有时用于虚拟。表“即使时有假设含义，一般用even if。Well make trip even if(though) the weather is bad. Even if I were in your place, I wouldnt take the job.虚拟4.“whether. or.可引导让步状语从句 Whether you believe it or not, it is true.5.“no matter + wh-引导让步状语从句引导让步状语从句时“疑问句-ever相当于“no matter +疑问词，此时：no matter who = whoeverno matter what = whateverno matter which = whicheverno matter where = whereverno matter how = howeverNo matter what happened, he would not mind.Its a nice room no matter whom (whoever) it belongs to.6.“no matter + wh-结构只能引导让步状语从句，而“wh-ever形式除引导让步状语从句外，还可以引导名词性从句。引导名词性从句时：whoever = anyone who任何的人whatever = anything that任何的事物whenever = anyplace where任何的地方I will give the book to whoever needs it.I like whatever you like.虽然却，尽管但 He walks when he might take a taxi.本应.，可以.却.。when从句用虚拟式为：could/should . have done She stopped trying when she might succeed next time.8.while引导让步状语从句时置于主句前，与though同，但though从句可到装，while从句不可倒装。9.让步状语从句中用一般现在时表将来。 No matter what he is, he will be punished.十、状语从句的省略现象当状语从句的主语与主句的主语一样或为it, 同时从句谓语含be动词，就可省去从句的主语和be动词。时间状语从句中：Dont speak until (you are) spoken to.While (I was) in Beijing, I lived with my uncle.I want to go swimming when (it is) possible.条件状语从句中：e tomorrow if (it is) possible.If (it is) so, you would be punished.Unless (it is) repaired, the TV set is of no use.方式状语从句中：She stood at the gate as if (she was) waiting for someone.其他状语从句中：Though (it was) cold, he still wore a shirt.Fill in the blanks with proper words where (it is) necessary.练习一、用适当的连词填空：1.
