⾼考状语从句讲解和练习题定义——在复合句中由从句表⽰的状语称作状语从句，状语从句由从属连词引导，也可以由⼀个起连词作⽤的词组引导，有时甚⾄不需要连词⽽直接和主句连接起来。

类型——时间、地点、原因、结果、条件、⽬的、让步、⽅式、⽐较状语从句。

1.引导词when, while, as, as soon as, once, before, after, every time, each time, since, whenever, ever since, until ,till等。

2.whenever, each time, every time的⽤法。

注：whenever=no matter whenevery time / each time 每次，whenever 每当······时，表⽰习惯性、经常性的动作。

Whenever we met with difficulties, they came to help us.Each time he came to town he would visit our school.Eevery time I went to his house, he was out.注：whenever=no matter whenwhenever既可以引导时间从句也可引导名词性从句，no matter when只可以引导时间状语从句。

It does not matter whenever the party begins.3.before的汉英表达1）before的基本含义是“在·····以前”The train had left before he got to the station.注意：与before对应的是after引导的时间状语从句，表“在·····之后”。

状语从句状语从句分为：时间、原因、比较、条件、目的、结果等状语从句。

一．时间状语从句. 连接词有：when, while, before, after, since, till, as soon as etc.*解题关键：要弄清主从句时态呼应关系1）如何使用好“when”应分析了解下列例句。

eg. 1. I ________(listen) to the music when there was a knock at the door. (主:过进;从:一过) 注：此句中when 理解为正在这时。

2. When I was walking past the tree I ______ (see) a cat. (主: 一过;从:过进)注：此句中when 理解为当。

的时候。

可与while 互换。

由so that（从句谓语一般没有情态动词），so …… that，such …… that 等引导。

结果状语从句表示结果，通常位于主句之后。

1.so that 可以引导目的状语从句，也可以引导结果状语从句。

①He worried so that he couldn’t sleep.他急得睡不着。

(so that 引导结果状语从句)②It was very cold, so that the river froze.天气寒冷，河水都结冰了。

(so that 引导结果状语从句)③I came to the class early so that I could see the classmate beside me.我赶早来上课，以便早点看到我旁边的同学。

状语从句总结一、原因状语从句(1)原因状语从句通常由because, since, as, for引导。

(2)because表示直接原因，语气最强。

because引导的原因状语从句多放在主句之后。

回答由why提出的问题，只能用because。

此外，because和so不能同用在一个句子里。

例如：------Why aren’t going there?------Because I don’t want to.since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴于……”。

例如：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散散步吧。

as和since语气较弱，一般用来表示明显的原因。

由as和since引导的原因状语从居多放在句首。

例如：As he has no car, he can’t get there easily.Since we have no money, we can’t buy it.(3)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。

如:I decided to stop and have lunch, for I was feeling quite hungry.练习：I was late for class yesterday _______ there was something wrongwith my bike.He took off his coat _______ he felt hot.you can’t answer the question, I’ll ask s omeone else.二、结果状语从句(1)结果状语从句由so…that, such…that, so that引导。

(2)so…that语such...that可以互换。

状语从句（adverbial clause）复习要点：掌握句法功能，记住连接词语法意义：状语从句是复合句中的一种，整个从句作主句的状语，修饰主句中的谓语动词、形容词、或副词。

置于句首时，状语从句后面一般要有逗号隔开；如果状语从句置于句尾，则从句一般不用逗号。

按照所作的状语和意义可分为时间、地点、原因、目的、结果、条件、让步、方式和比较等九种状语从句。

具体如下：一、时间状语从句（Adverbial Clauses of Time）时间状语从句通常由when,whenever,as,while,before,after,assoon as,since,once,no sooner...then,hardly/scarcely...when,tiLl/until 以及the moment,directly,immediately,the second,thefirst time,next time,every time,等引导。

1.由when,as,while 引导的状语从句：1）when 引导时间状语从句，表示当···，其谓语动词可以是延续性的，也可以是非延续性的，其作用最广泛。

When spring comes,trees turn green,When it rains,I usually go to work by taxi.When we were having lunch,the light went out.I will ring you up when I return.When she pressed the button,the lift stopped.He was eating his breakfast when the doorbell rang.be about to do...when...“就在那/这时，（突然）另一个动作发生了，在这儿只能用when。

状语从句状语从句在句中作状语，修饰主句中的动词、形容词或副词等。

状语从句放在主句之前时，常用逗号分开；放在主句之后，一般不用逗号。

状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点9种。

1．时间状语从句1) 时间状语从句常用连词有when, as, while, before, after, since, till, until, as soon as, hardly … when …, no sooner … than …., the moment等。

2) 时间状语从句一般不用将来时。

因此，主句若为将来时，时间状语从句要用一般现在时。

I’ll go on with the work when I come back tomorrow.3) 连词when, while, as都表示“当……的时候”，但有区别。

as 多用于口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。

As he was eating his breakfast, he heard the door bell ring. (强调同一时间)As going out, it began to rain. (强调两个动作紧接着先后发生)As spring warms the good earth, all flowers being to bloom. (as有“随着”的含义)when 强调“特定时间”。

When spring comes, he feels like a trip.When he was eating his breakfast, he heard the door bell ring.while 表示的时间是一段，而不是一点。

while 有时还有对比的含义，意为“然而”。

While he was eating his breakfast, he heard the door bell ring. (强调吃饭的过程)While I was reading, he was playing. (有对比的含义)4) till / until表示“一直到……”时，主句和从句都用肯定式；表示“直到……才……”时，主句用否定式，从句用肯定式。

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, themoment/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。

第十二讲状语从句（含练习与答案）担任状语的从句叫状语从句，可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。

when引导的从句动词可以是延续性的或短暂性的，在“be…when…”句式中when表“at that time(就在这时)”意。

while引导的从句中动词必须是延续性的；有时并不表示时间，而表示对比，意“而”、“却”，并列连词，表对照。

As 强调主、从句动作同时或几乎同时发生，意为“一边…一边…”。

When I got home I found the door locked.While / When / as we were working in the fields, it suddenly began to rain.He was wandering through the streets when a bike hit him.I was about to go out when the telephone rang.I had just arrived at school when my wife phoned me to go home.His pencil is red, while mine is yellow.John sang happily as he went along.※ till与until一般情况下可以互换，但until可以位于句首，till则不能。
