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。

as far as/so far as。
provided/providing(that)。

高中英语状语从句专项讲解及练习（有答案）
高中英语状语从句专项讲解及练习（有答案）状语从句1、地点状语从句地点状语从句表示地点、方位，这类从句通常由where, wherever, anywhere, everywhere引导。

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。

状语从句在复合句中作状语，位置灵活。
状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。
（一）时间状语从句1.when, as, whilea.when表时间，从句既可以用延续性动词，又可以用瞬间动词。
Eg: When I get there I will call you.如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be 可省。
Eg：When （you are）in trouble, you can ask her for help.如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。
Eg：When I came into the room(When coming into the room), I found the light was off.b.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。
主句的谓语动词通常是非延续性动词。
Eg: He came in while I was reading a book.I met her while I was in school.c. as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行。
同时可表示主句的动作随着从句的动作的变化而变化。
Eg: He jumps as he sings.As the wind rose, the noise increased.2.before(在……之前)与after（在……之后）Eg：See me before you leave.I saw them after I arrived.3. till与until肯定形式表示的意思是"做某事直至某时"。
否定形式表达的意思是"直至某时才做某事"。
Eg: Wait till/untill I call you.等着直到我叫你。
She didn't arrive till/until 6 o'clock..她直到6点才到但是置于句首时只可用untill.Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。
否定形式有另外两种表达方式：(1)Not until …在句首，主句用倒装。
Man did not know what heat was until the early years of the 19th century.=Not until the early years of the 19th century did man know what heat was.(2)It is not until…that…He will not go to bed until his mother comes home.=It is not until his mother comes home that he will go to bed.4. as soon as/the moment/the instant/the second/the minute/immediately和hardly/scarcely…when, no sooner…thana. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和从句的动作同时发生。
译为“一……就”Eg：As soon as she heard the news, she began crying.b. hardly/scarcely…when, no sooner…than都可以表示"一……就……"的意思，但主句谓语动词一般要用过去完成时，从句谓语动词要用一般过去时。
Eg：I had hardly / scarcely got home when it began to rain.I had no sooner got home than it began to rain.注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构：Hardly / Scarcely had I got home when it began to rain.No sooner had I got home than it began to rain。

(so) that/in order that（so）that/in order that表示“为了，以便”，引导的目的状语从句要用虚拟语气。
Eg: He shouted at the top of his voice so that/in order that he might be heard.如果表示“为了，以便”的目的状语从句的主语与主句的主语相同，可用in order to或so as to替代。
Eg：I came early so as to/in order to catch the first train.3.lest, for fear that, in caselest, for fear that, in case表示“以免，以防”。
其中lest, for fear that要用(should)+动词原形的虚拟语气；in case 后的从句可用虚拟语气，也可用陈述语气。
Eg：I will not make a noise lest/ for fear that I (should) disturb you.Take your umbrella in case it rains.Ex.1.
