英语中的九大状语从句状语从句在主从复合句中修饰主句中的动词、形容词或副词等,按意义可以分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。
一.时间状语从句。
通常由从属连词when, whenever, as, while, before, after, as soon as, till, until, since, once (一旦), hardly……when…, no sooner…….than…; 等引导。
例如:The cyclist started just as the lights changed to green.Whenever we met with difficulties , they cam to help us.He didn’t leave his office until he had finished the day’s work.应注意的问题1.在时间状语从句中,通常要用动词的一般现在时态表示一般将来时态,用一般过去时态表示过去将来时态。
但when 引导一般疑问句或名词性从句时不受上述语法规则的限制,因此,应该加以区分。
例如:When China will enter WTO depends on the bilateral (双边的)joint efforts.Once you understand the rules of the game, you’ll enjoy it.2.when , while, as 的不同用法。
一般说来,当主、从句的动作是同时发生的事,三者可以换用。
when 既可以引导一个持续动作,也可以引导一个短暂动作,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;while 引导的动作必须是持续性的,强调主句和从句的动作同时发生,往往侧重主句和从句动作的对比;as 用于引导“在某行为的继续中发生某事”的“继续之行为”,所以多与过去进行时连用,翻译成“一边……一边……”或者表示动作的变化,翻译成“随着……”。

实用标准文案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、比较、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 sooner than,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。
1.表示“一···就···”的句型1) as soon as/onceAs soon as he arrives, I'll call you.他一到,我就给你打电话。
(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 ...”)2) on doing sth/on one's + n.作时间状语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,电话就响了。
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, thesecond The moment I saw him, I recognized him.我一看见他,就认出了他。
We'll 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 的用法精彩文档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。
②在 when引导时间状语从句时,如果从句主语与主句主语相同或为it ,且从句有 be 动词,则从句可省主语和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 when(she is) doing her homework.当她做作业时,总是听音乐。
③when在下列结构中 ,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 one's way ... when, be on the point of doing ... when(参见“连词”部分 when的用法)2) while 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,我很安全。
注意 while除引导时间状语从句外,还引导对比句,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① 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。
②as 还可说明两种正在发展或变化的情况,“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。
③a s 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。
④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。
⑤as 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①b efore 引导的时间状语从句不用否定式谓语。
Before they got to the bus stop, the bus had gone.在他们到达公共汽车站之前,公共汽车已经走了。
②在“ It be +时间段+ before从句”句型中,肯定句译成“ (之后)才”,否定句译成“ 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...“很久才···”It wasn't 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 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 wasn't 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“未来得及”He had measured me before I could get a word.我还未来得及插话,他就量好了尺寸。
▲b efore 可译成“趁着还没”I'll write it down before I forget.趁着还没忘我要把它写下来。
4. until和till1)“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)“终止性动词的否定式 + until ”表示“直到···才”。
He didn't 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 compound.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.自从李先生回来以后,他一直在这儿。
I haven't 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。
I've known Mr. Smith since I was a boy.我小的时候就认识史密斯先生了。
6.时间状语从句的省略式当时间状语从句的主语和主句主语相同或为 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。
