【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 t he sun sets.）否定句：She didn’t arrive until 6 o’clock. 她直到6点才到。
