高考英语课堂专题精练(20分钟)：状语从句

完整版)高中英语状语从句讲解及练习状语从句是指在句中作状语的从句，可以分为时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。

时间状语从句的连词有when、as、while、until、not…until、before、after、since、the minute、the moment、each、every、next、the first time等。

时间状语从句一般使用一般现在时或一般过去时。

当使用when、as、while这三个连词引导时间状语从句时，它们都表示“当…的时候”，但侧重点有所不同。

例如，当使用when引导时间状语从句时，从句的主语与主句主语相同，如果谓语动词是be动词，则从句主语和be可以省略。

而as则不仅表示“当…的时候”，还可以表示“一面…一面”或“随着”。

而while则强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。

当使用until、not…until时，它们表示“直到…才”。

在肯定句中，主句常用延续性动词；在否定句中，主句常用短暂性动词。

需要注意的是，当not until…位于句首时，主句需要倒装。

例如，“Not until you had explained how did I manage to do it.”It was dark when he finally returned。

XXX the machine type upon seeing it。

As soon as I arrived home。

it began to rain。

Hardly had I arrived home when it began to rain。

XXX: real XXX: if。

even if/though。

unless/if。

not。

as long as/so long as。

as far as/so far as。

provided/providing(that)。

状语从句一、知识框架二、知识梳理（一）定义在复合句中修饰主句中的动词、形容词和副词的从句叫状语从句。

状语从句根据它表达的意思不同可分为时间状语从句、地点状语从句、条件状语从句、比较状语从句、目的状语从句、结果状语从句、方式状语从句、让步状语从句和原因状语从句等。

状语从句如果放在主句前通常用逗号分开，放在主句之后一般不用逗号。

（二）九类状语从句一）时间状语从句1、从属连词分类1）基本类包括when, while, as, whenever, before, after, since, till, until, once (一旦), as soon as等。

Did anyone call when I was out?We have known each other since we were children.You’ll feel better after you take the pills.Make sure that all the lights are off before you go to bed.2）名词类包括the moment, the minute, the second, the instant, every time, each time, (the) next time, the last time, any time, the first time等。

地点状语从句与定语从句的区别:在于分句在句中作什么成分。

作状语，则是状语从句；作定语修饰名词，则是定语从句。

where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。

如：Go back where you came from.(where引导地点状语从句）Go back to the village where you came from.(where引导定语从句，修饰village)We went home, where we had dinner. (where引导定语从句，修饰home)2、原因状语从句原因状语从句一般由because(因为)，since(既然)，now that(既然，因为)，as(由于)等连词引导。

（1）because表示直接的原因，表示原因的语气最强，常表示必然的因果关系。

回答why引起的特殊疑问句，只能用because。

Jane wore a raincoat because it was raining.因为天下雨，所以詹穿着雨衣。

He is absent today because he is ill.他今天缺课，因为他病了。

（2）since表示对方已经知晓、无须加以说明的原因或事实，语气比because稍弱。

专题十一状语从句状语从句在高考试题中由于其他从句的干扰，以及倒装句,强调句的介入，使得状语从句更为复杂。

状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。

状语从句1. 时间状语从句常见的连词(组）：when, while， as， before, after, once, till, until， as soon as， now that， hardly 。

..when, scarcely 。

.when， no sooner .。

than等.可以引导时间状语从句的副（介)词（短语）或名词短语：directly， instantly， immediately, by the time, the moment, the second， the minute， the instant, every time, each time， next time， the last time等。

注意点如下：(1） when， while, as引导的时间状语从句as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。

when(at or during the time）既可以表示在某一点的时候，又可以表示在某一段时间内,主句与从句的动作或事情可以同时发生也可以先后发生.while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态;当when表示a period of time时，两者可以互换。

She came up as I was cooking。

(同时）在我做饭时，她走了过来.When we were at school, we went to the library every day.(在一段时间内）当我们在学校时，每天都去图书馆。

While they were watching TV, I was preparing myself for the coming examination.他们在看电视，而我在为即将到来的考试做准备.Strike while the iron is hot。
