状语从句9种全.docx

1、状语从句9种全状语从句 在复合句中作状语的从句叫状语从句。状语从句有时刻、地址、缘故、目的、结果、条件、方式、比较、妥协等种类。一、时刻状语从句引导时刻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, n

2、ext time, last time, all the time, by the time, directly, immediately, instantly等。1.表示“一就”的句型1) as soon as/once As soon as he arrives, Ill call you.他一到，我就给你打。（as soon as 偏重时刻或动作前后衔接紧，而once偏重条件，表示“一旦.”）2) on doing sth/on ones + n.作时刻状语 On arriving at the station, the thief was arrested. 一抵达车站，那个小偷就被批

3、捕了。 On his arrival in Paris, he was recognized as a noble and thrown into prison. 他一抵达巴黎，就被认出是一个贵族，并被投入牢狱。3) no sooner .than , hardly/scarcely.when 它们表“一就”。结构中的否定词放在句首时，主句要倒装。（主句都用过去完成时，从句用一样过去时。） No sooner had he reached home than it began to rain. 他刚抵家，天就开始下雨了。 Hardly/Scarcely had I entered the ro

4、om 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 scarcely（hardly）entered the room when the phone rang.4）the moment, the instant, the minute, the second The moment I saw him, I recognized him.

5、 我一看见他，就认出了他。 Well leave the minute you are ready. 你一预备好，咱们就动身。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引导时刻状语从句1) when的用法when既可指时刻点，也可指时刻段（即：从句动词能够是短暂的也可是延续的）；主从句动作可同时也可前后发生。 I was thin when I was a child. 当我是个小孩的时候,我很瘦。

6、 It was raining when I arrived.我抵达时，天正在下雨。在when引导时刻状语从句时，若是从句主语与主句主语相同或为it，且从句有be动词，那么从句可省主语和be动词，如： When (you are) in trouble, you can visit this man. 当你有麻烦时，能够找那个人。 She is always listening to music when（she is) doing her homework. 当她做作业时，老是听音乐。when在以下结构中, 译成“这时”,它引导的是并列句be about to do . when, be d

7、oing . when, had done when,be on ones way . when, be on the point of doing . when（参见“连词”部份when的用法）2）while用法while只能指一段时刻，从句中的动词必需是延续性动词。强调某一段时刻内发生主句动作，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，我很平安。注意 while除引导时刻状语从句外

8、，还引导对照句，作“但是”讲；并可在句首引出妥协状语从句作“尽管但”讲。 I like watching TV, while he likes reading. 我喜爱看电视，而他喜爱念书。 While he has his own car, he often uses mine. 尽管他自己有车，他却经常使用我的。3) as的用法 as引导时刻状语从句时常可和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还可说明两种正在进展或转变的情形，“随着.”的意思，表时刻的推移。如：As I get

9、 older, I get more optimistic.随着年龄的增加，我变得加倍乐观。as表“一边一边”，引出伴随动作。He hurried home, looking behind as he went.他慌忙地回家，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，相当于一个时刻状语从句。As a boy (when he was a boy), he was hopeless at maths.当他是小孩时，他对数学失去希望。3. before引导的时刻状语从句b

10、efore引导的时刻状语从句不用否定式谓语。Before they got to the bus stop, the bus had gone.在他们抵达公共汽车站之前，公共汽车已经走了。在“It be + 时刻段 + before从句”句型中，确信句译成“（以后）才”，否定句译成“就”。该句型有一样过去时、过去以后时、一样以后时三个时态，且有否定句。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.“好久才”It

11、 wasnt long before.did.“不久就.”It will be many years before the chemicals start to escape fromthe containers. 连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.好久他才再次入眠。It was a week before he could tell his story. 一个礼拜后他才能讲述他的经历。 It wasnt lo

12、ng before he told us about himself. 不久他就给咱们讲述了他自己的故事。before可译成“以后得及”He had measured me before I could get a word.我还以后得及插话，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)“延续性动词确信式+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

13、词的否定式+ 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.在教授到来以后，咱们才开始实验。4) not until放在句首时，主句倒装。Not until he graduated did he succeed in obtaining this compound. 直到他毕业他才成功取得这种化

14、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引导时刻状语从句，意为“自从时起”，主句要用完成时。Mr. Li has been here since he came back.自从李先生回来以后，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.我小的时候就熟悉史密斯先生了。6.时刻状语从句的省略式 那时刻状语从句的主语和主句主语相同或为it，从句又含be

15、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，永久也可不能被忘记。二、地址状语从句1.地址状语从句要紧由where, wherever anywhere, everywhere引导。 We must camp where we can get water. 咱们必需在能找到水的地址露营。 I will follow you wherever you go. 不管你到何处我都要跟从你。2.地址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址的名词作

16、先行词。 Go back where you came from.（where引导地址状语从句） Go back to the village where you came from.（where引导定语从句，village为先行词）三、缘故状语从句 缘故状语从句由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，用于告知对方不明白的缘故，语气最强，可用于强调句。 He didnt

17、 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，他没有和咱们一路去。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

18、延期了。2. since, as, now that引导的缘故状语从句，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，专门用于缘故已经清楚了的情形，一样译成“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. 既然你已经明白了那个秘密，我就没必要说了。as语气最弱，说明一样的因果关系，表显而易见的缘故或倒果为因的说法（可放在主句之前，亦可放在主句以后），如： As he didnt know much English, he got out his

19、dictionary and looked up the word “cough”. 他对英语知道不多，他拿出字典查找“cough”那个词。 As the ground is wet, it must have rained last night.（倒果为因） 昨晚必然下了雨，地面是湿的。 now that用来讲明一种新情形，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也能够表示缘故，属并列连词，不是说明直接缘故，而是对某种情形加以推断，表示补充说明理由。而推断的理由会因人而异。语气很弱，

20、它引出的分句必需放在另一分句后。 He must be ill, for he is absent today.4.缘故状语从句有时能够用分词形式表现。 As he was blind, he couldnt see anything. Being blind, he couldnt see anything.四、条件状语从句1由if, unless（if.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/providi

21、ng (that)（假假设）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+陈述句”的句型中，祈使句在意义上事实上相当于条件状语从句。 Use your head, and youll find a way. Hurry up or else

22、(otherwise) youll be late.3. if only也能够引导条件状语从句,只只是较少利用罢了。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.条件状语从句中一样要用一样此刻时态表以后。 I will go if you go.5.条件状语从句中的省略问题1)从句主语为it,又有系动词be时，能够省略从句中主语和be动词。 Come tomorrow if (it is) possible. If so, you must get back and get it. 还有诸如if necess

23、ary“若是有必要”，if any“若是有”，if in need“假设需要”。2）若是if从句的主语和主句的主语一致，谓语动词又有be,能够把从句中的主语和be省略掉。 If (water is) heated, water sends out steam.6.条件句中的虚拟与倒装 if引导的条件状语从句假设与过去或此刻事实不符，或对以后进行不可能的假设，就要用虚拟语气。（详见虚拟语气部份）省略if的虚拟条件从句：假设条件从句的谓语动词有were, had或should,能够把if省去，而把were，had或should移到主语前组成倒装。Had I arrived there earlie

24、r, 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）（以避免），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 mig

25、ht 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 that（lest）he 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

26、succeed.六、结果状语从句1.经常使用的连词有so that，so . that, such.that, that（带古英语痕迹）。（结果状语从句中一样无情态动词） 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 + adj（adv) + 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+ad

27、j.+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 can

28、t 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 t

29、each 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、比较状语从句经常使用连词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 I（study）the more . the m

30、ore.引导, 且常常以省略形式显现 The harder you try, the better you will understand.九、妥协状语从句由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这两个连词用法大体一样，只是前者口语化，后者较正式，常位于句首，都不与but连用，但能够和yet，still，nevertheless连用。though还可作副词单独放在句尾，表示“但是”的意思。 Although

31、 the TV set is very dear, I still want to buy it. Though /Although he was worn out, he kept on working.2. as引导妥协状语时，从句部份用倒装语序，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，也能够用though（不太经常使用），但
