初中状语从句表格整理
初中状语从句表格整理状语从句是一种副词性从句，用于修饰主句的动词、形容词或副词。
根据修饰的方面，状语从句可以分为九种不同类型。
当表示“当。
时”的状况时，我们可以使用when引导的从句。
例如：“当我进入房间时，他正在写信。
”XXX引导的从句表示“在某一段时间里”或“在。
期间”。
例如：“他们在下雨的时候出去了，而我则一直待在家里。
”使用as引导的从句表示随着时间的推移，某种情况逐渐发生或变化。
例如：“随着时间的推移，我越来越喜欢中国。
”XXX表示“在。
之前”或“才。
”。
例如：“成为一名老师之前，你需要成为一名学生。
”使用after表示“在。
之后”。
例如：“他比赛开始后才到达。
”till或until表示“直到。
为止”，但是要注意主句的动词类型。
如果是持续性动作，我们需要使用肯定式；如果是瞬间动作，我们需要使用否定式。
例如：“我等到他回来才停止工作。
”或者“直到十一点钟，她都没有停止工作。
”状语从句可以帮助我们更加准确地表达自己的意思，使语言更加流畅自然。
因此，在写作或口语中，我们应该尽可能地熟练掌握各种类型的状语从句。
Since 1978.China has XXX。
The verb in the main clause should be continuous。
while the XXX by "since" should have an instantaneous verb。
A comma should be used to separate the subordinate clause from the main clause when the subordinate clause comes before the main clause。
If the subordinate clause comes after the main clause。
XXX needed.As soon as I arrive in Shanghai。

④ The students took notes as they listened ．（listen 为延续性动词）二、when 从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while 和as 从句的谓语动作必须是和主句谓语动作同时发生。
1．从句动作在主句动作前发生，只用 when 。
①When he had finished his homework ，he took a short rest ．（finished 先发生） ②When I got to the airport ，the guests had left ．（got to 后发生）2．从句动作和主句动作同时发生，且从句动作为延续性动词时，when ，while ，as 都可使用。
①When ／While ／As we were dancing ，a stranger came in ．（dance 为延续性动词） ②When ／While ／As she was making a phonecall ，I was writing a letter ．（make 为延续性动词）3．当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as 。

状语从句是副词性从句，它在句子中担任状语，修饰主句的动词、形容词、副词或句子。
根注意：时间状语从句(1)当主句是一般将来时、祈使句或主句中含有情态动词，这些词引导的从句要用一般现在时（主将从现）Don’t go to bed until you finish your homework.(2)When while as 的辨析A．相同点：都是“当。
时“不同点：when后用短暂性动词，指时间点，此时该从句的时态是一般现在时或一般过去时，后也可用延续性动词，指时间段，时态通常是进行时。
He was watching Tv when I came back.B.while引导的从句后必须是延续性动词，指时间段，常用进行时Someone knocked at the door while she was cooking.C.as着重指主从句同时发生“一边…一边“As we walked,we talked.(3)since 引导的从句一般用过去时，主句用现在完成时I have learnt English since I was 4 .目的状语和结果状语(1)目的状语从句引导词：so that. in order that从句中常用情态动词。
★so that既可引导目的状语从句，又可引导结果状语从句。
区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, mightwould等。
2)从意思上看，目的状语从句往往表示的目的很明确。
例如：Speak clearly so that they may understand you. (目的状语从句)Jack is badly ill so that he has to rest. (结果状语从句)(2)结果状语从句引导词：so...that,such...that.(3)so与such的区别①so+形+a/an+名单=such+a/an+形+名单②so+many/much/few/little+形+名(只能用so, 不用such)例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he can’t go to the cinema with you.③such+形+不可数名词/可数名词复数(4)so...that与too...to和...enough to间转换The apple is so dear that I can’t buy it.=The apple is too dear for me to buy.=The apple isn’t cheap enough for me to buy.。

状语从句状语从句是副词性从句，它在句子中担任状语，修饰主句的动词、形容词、副词或句子。
根据修饰的方面，状语从句可以分为以下九种。
种类从属连词例句要点归纳时间状语从句whenWhen I came into the room, he was writing a letter.when指的是“当…时”。
从句中的动词可表延续性动作，也可表瞬间性动作※I was walking along the street when(这时) suddenly Tompatted me on the shoulder .when意为“这时”或“在那时”,这时when分句一般位于句末。
whileWhile it was raining, they went out.※All of us are working hard while he is sleeping.( 并列连词“然而”)while指“在某一段时间里”，“在…期间”，while引导的动作必须是持续性的。
asHe hurried home, looking behind as he went.他赶快回家，边走边向后看。
As (随着)time goes by, I like China better.as（一边...一边）引导持续性动作，强调主句和从句的动作同时发生；“随着”。
beforeBe a pupil before you become a teacher.I finished my task before I went home.before译为“在…之前, 才, 就”after He arrived after the game started.在…之后tilluntilWe waited till (until)he came back .直到She didn’t stop working until eleven o’clock .直到…才主句谓语动词为延续性，常用肯定式；主句谓语动词为瞬间性，常用否定式，可用before替换since,Great changes have taken place in China since 1978.It’s 8 years since I taught here.其从句通常用一般过去时，主句谓语动词通常用完成时常用于It is /was …since句型as soon as As soon as I arrive in Shanghai, I’ll write to you.No sooner had he reached home than it began to rain“一…就”同：i mmediately, directly, instantly, the minute / moment ,no sooner…than, hardly (scarcely)…whenthe firsttimeThe first time I saw him, he was a school teacher同理：every time, each time, any time ,the last time, by the time可引导时间状语从句地点状语从句wherewhereverWhere there is water there is life.Wherever you go, you must obey the law.where与wherever意义基本相同，但后者语气较强。
in which只在定语从句中的某些情况下，才可以与where替换原因状语从句because I was late yesterday because I was ill.because用来回答why 的问题，语气最强一般放在主句之后since Since (既然)everyone is here, let’s begin our meeting.since表示既然或全已知的理由,稍加分析即可表明的原因,多放句首as As（由于） he didn’t know m uch E nglish, he looked up the wordin the dictionary .从句常放在句首，说明次要的原因，主句说明结果，常用于口语中。
for It must have rained last night, for the ground is still wet.for连接的是并列句，表补充说明的原因，常位于主句后。
