状语从句知识讲解基本概念定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。

状语句通常由一个连词引起，也可以由一个起连词作用的词组引起，有时甚至不需要连词直接和主句连接起来。

状语从句一般分为九大类状语从句类别时间状语从句地点状语从句原因状语从句目的状语从句结果状语从句条件状语从句方式状语从句比较状语从句让步状语从句一、时间状语从句1．when, while和as1) when既可引导一个持续动作，也可引导一个短暂动作，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。

如：When I lived there, I used to go to the seashore on Sundays.When the film ended, the people went back.2）while引导的从句的谓语动词动作必须是持续的，侧重主句动作和从句动作相对比，同时while引导的从句一般用进行时。

如：While I was wondering at this, our schoolmaster took his place.3) as引导一个持续性动作，多用于主句和从句动作同时发生。

如：He hurried home, looking behind as he went.John sings as he works.4) when还可用作并列连词使用，其意义是“那时、这时”，相当于and this/that time.常用于下列句式：Somebody was doing someth ing when…Somebody was about to /going to do something/ on the point of doing sth. when…Somebody had just / hardly done something when…过去时此外when还表示原因“既然”。

Father was preparing a report while I was playing PC games.3)常用as 的情况：一边⋯一边；表示随着短暂动作的发生，另一行为伴随发生As he talked on, he got more and more excited.until 和till 的用法表示“一直到⋯”时，主句和从句都用肯定式；I will wait until/ till the concert is over. 表示“直到⋯才⋯”是，主句用否定，从句用肯定式。

它可以用来表示时间、地点、条件、原因、结果、目的、让步、比较、方式等。

状语从句是一个较大的语法项目，也是近几年高考题中常见的重点考点。

高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考的热点，应做充分的准备。

同时对方式状语从句也应引起重视。

不同的状语从句所使用的连接词也各不相同。

如下表所示：状语从句名称连接词时间状语从句when, as, while, whenever, after, before, till/until, since, once, as soon as/the moment, by the time, no sooner…than, hardly…when, every time等地点状语从句where和wherever条件状语从句if, unless, as long as, on condition that, if only(=if)原因状语从句because, since, as, now that(既然)结果状语从句so that(从句谓语动词一般没有情态动词), so…that, such…that目的状语从句so, so that(从句谓语常有情态动词), in order that, in case(以防，以免)让步状语从句although, though, as(常用倒装结构), even if/though, however, whatever, whether…or, no matter who(when, what, where…)等比较状语从句than, as…as, the more…the more方式状语从句as, as if/though, the way, rather than等一、时间状语从句1. while, when, as引导时间状语从句时的区别(1) while引导的状语从句中谓语动词必须是持续性动词。

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。
