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)。

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。
I'll do it for you since you are busy.既然你忙，我来替你做吧。

A. 因为gave后面已经有表示物的直接宾语了，排除代词A、C、和D.however意为“无论如何”；whenever意为“每当…”，根据句意，只有选C，意义才通.2. A. 因为前面已经连词though了，所以不再需要连词了.Hard-working though he was=Although he was hard-working.3. B. 因为as引导让步状语从句，要求将从句的表语或状语等放到句首.而although, while表示让步时，都用正常语序；另外，though引导的让步状语从句，其表语或状语等可提前也可不提前.4. C. 因为immediately, instantly, directly和the moment, the instant, the minute等都可以用作连词，引导时间状语从句，相当于as soon as.5. C. 因为表示“正要做某事时，突然又发生另一件事”的句型是：was /were just about to do sth. when…did…或was /were just on the point of doing sth. when…did…6. C. 因为not…until…“直到…才…”，再接before语意上不通，要用after.7. C. 因为no matter后一定要接疑问词或whether.8. C. 引导状语从句时no matter how=however，其后接形容词或副词，只有C正确.9. C. unless“除非、如果不”.句意是：大多数动物与其它不同种类的动物都没有什么联系，除非是把它们猎为食物.10. A. 句意是：虽然他认为他在帮我们做工，但事实上他是在挡事.11. B. 表示主、从句的谓语动词同时变化的“随着…”只能用as.12. B. 因为keep the portrait 〔把照片放在…〕后面一定是指所放的“地方”了，所以用where 〔在…的地方〕引导一个地点状语从句.13. C. 因为非谓语动词的逻辑主语就是句子的主语，mistakes不能check，排除A和D；若用B，则前后是两个句子，又无连词，排除B.14.
