高考英语 状语从句教案
状语从句一、概述：状语从句修饰主句中的动词、形容词、副词等，在复合句中作状语。
引导状语从句的关联词是从属连词。
状语从句用陈述句语序，一般位于复合句的句首或句末。
当从句放在主句前面时，常用逗号与主句隔开。
状语从句根据其在句中的不同作用可以分为时间、地点、原因、目的、结果、条件、让步、方式和比较状语从句九种。
二、用法：（一）时间状语从句的用法：1、注意点：⑴在时间、条件状语从句中，谓语动词一般不用将来时态表示将来，而用一般现在时态代替一般将来时态，用一般过去时态代替过去将来时态，用现在完成时态代替将来完成时态。
如：When he comes here，I will let you know. When I have finished reading the book，I will tell you.注意：when可以引导时间状语从句，还可以引导宾语、主语等名词性从句；if可以引导条件状语从句，也可以引导宾语从句（引导条件状语从句时，意为“如果，假如”，引导宾语从句时，意为“是否”）；注意当它们引导时间和条件状语从句时，要用一般现在时态表示将来，引导宾语等名词性从句时，仍然要用一般将来时态表示将来。
如：When he comes here, please tell me. W hen he will come here hasn’t been decided yet.If he has any questions，he will come to ask me. Tell me if you will go to school tomorrow.(2)时间、条件、方式、让步等状语从句常常可以转换成省略形式或简单句句子成分。
①when，while，as，if，though，as if等引导时间、条件、方式、让步等状语从句时，若从句和主句的主语一致或主句的主语是it且含有be动词时，可以将从句中的主语连同后面的be动词一起省略。

状语从句一．状语从句的定义：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。
状语从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二．状语从句的分类：1．时间状语从句：在时间状语从句中，要注意时态一致，一般情况下主句是将来时的时候，从句要用一般现在时。
可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，又可分类如下：（1）表示同时性，即主从句的谓语动作同时发生或几乎同时发生。
其连词有：when （当……的时候）, while（当……的时候）, as（当……的时候）, once（一旦……）as soon as（一……就……）, the time（当……的时刻）, the moment （当……的时刻）,by the time（到……时候为止）, next time(下次), the first time(第一次……的时候), the last time(上次……的时候)，immediately（一……就……）, instantly（一……就……）,directly（一……就……）以下关联词引起的句子中，前面常用过去完成时，后面用一般过去时hardly /scarcely…when…（刚……就……）, no sooner…than…（刚……就……）Strike while the iron is hot.趁热打铁。
While I am washing the floor, you can be cleaning the windows.（while含有对比的意思）我洗地板的时候，你可以擦窗户。
As / When I came home, I met an old schoolmate of mine.我回家的时候遇到了我的一位老同学。
I'll ring you up as soon as I get an answer from him.我一有他的答复就给你打电话。
Once you see him, you will never forget him. 你一旦见过他，就不会忘了他的。
Hardly had we got into the country when it began to rain. 我们一到乡下就开始下雨了。
= We had hardly got into the country when it began to rain.No sooner had he come home than she started complaining. 他一到家她就开始抱怨。
= He had no sooner come home than she started complaining.He made for the door directly he heard the knock. 他一听到敲门声就向门口走去。
She rushed into the room immediately / the moment she heard the noise.她一听到声音就冲进房间He left me a good impression the first time I met him.我第一次见他时，他给我留下了好印象。

★as、when、while用法一览表类别作用例句asas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 that )既可以表示在某一点的时候，又可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。
如果表示从句的动作在主句的动作"之前"或"之后"发生时，多用when（=after）, 不用as或while。
此外，when还含有"at that moment"的意思（= and then），引起的句子不能放在句首，也不能用as, while来替换。
