1、状语从句包括时间状语从句、地点状语从句、条件状语从句、让步状语从句、原因状语从句、目的状语从句和结果状语从句。状语从句的考查主要集中在连接词的掌握上，尤其要重视as, until, before, since, when, in case等连词的各种语义功能和语法功能。其考点主要包括： 1考查状语从句的连接词。要掌握每个连词的含义及其用法，还有它们之间的一些区别。如：时间状语从句的连词有while, when，as，as soon as，until，notuntil，before, after，since等； 条件状语从句的连词有 if，unless, in case, on conditio

2、n that, provided (that), supposing, suppose (that)等； 结果状语从句的连词有sothat(如此以至于)，suchthat(如此以至于)等。 2考查固定搭配和习惯用法的连接词。如：no soonerthan/hardlywhen(一就); the moment/minute，directly等的连词功能。3考查不同性质的连词在不同的语境中所表现的不同意义，如as既能引导时间状语从句，又能引导原因状语从句和让步状语从句； where引导地点状语从句和定语从句等。4考查状语从句的时态。主要考查时间、条件、让步状语从句用一般现在时表将来，以及一般过去时
