考向15 门派众多，武艺纷繁的语法江湖---“状语从句” 状语从句在高考中出现频率高，而且状语从句的类型也比较多，在学习过程中我们需要掌握：一是各从句连词的含义；二是不同类型状语从句在使用过程中的注意事项；三是特殊用法，例如倒装和省略等。 常见的状语从句从属连词有： 引导时间状语从句的：after, before, when, as, while, since, until, till, as soon as 引导原因状语从句的：because, since, as 引导让步状语从句的：although, though, no matter（无论）, even if (though) 引导条件状语从句的：if, unless, once, so (as) long as 引导结果状语从句的：so … that …, such … that … 引导目的状语从句的：so that …, in order that … 引导比较状语从句的：as … as …, not so (as) … as …, … than … 引导方式状语从句的：as if … 考点一：时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. （一）as、when、while用法一览表。 类别 作 用 例 句 as 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同时发生， 或几乎同时发生。 She came up as I was cooking.(同时) The runners started as the gun went off.(几乎同时) 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。 It was raining when we arrived.(指时间点) When we were at school, we went to the library every day.(在一段时间内) while while意思是“当……的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续动词，侧重主句动作和从句动作相对比。在when表示a period of time时，两者可以互换。 Please don’t talk so loud while others are working. He fell asleep while/when reading. Strike while the iron is hot.(用as或when不可，这里的while意思是“趁……”) 注意： 1）当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或 while。 When you have finished your work, you may have a rest. 赶完活后，你可以休息一下。 2）As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着” Eg: He sang as he danced.(一面```一面) 从句表示"随时间推移"连词能用as，不用when 或while。例如： As the day went on, the weather got worse.　日子一天天过去，天气越变越坏。 3）wh
