状语从句讲义(讲稿)
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。

【网络构建】一、状语从句概述考向二状语从句的连接词概念：在复合句中作状语的从句叫作状语从句。
状语从句一般修饰主句中的动词、形容词或副词等。
功能：九大状语从句分别表示（时间、条件、原因、地点、目的、结果、方式、让步、比较）等意义。
位置：位置灵活，可用于主句之前或之后。
1．when, while, as引导的时间状语从句2. 比较until和till此两个连词意义相同。
肯定形式表示的意思是＂做某事直至某时＂，动词必须是延续性的。
否定形式表达的意思是＂直至某时才做某事＂。
动词为延续性或非延续性都可以。
正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
肯定句：I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
（在肯定句中可用before代替。
例如：Let’s get in the wheat before the sun sets.）否定句：She didn’t arrive until 6 o’clock. 她直到6点才到。
