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，not…until，before, after，since等； 条件状语从句的连词有 if，unless, in case, on condition that, provided (that), supposing, suppose (that)等； 结果状语从句的连词有so…that(如此……以至于)，such…that(如此……以至于)等。
2．考查固定搭配和习惯用法的连接词。如：no sooner…than/hardly…when(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，以及一般过去时代替过去将来时的用法。
5．考查状语从句的省略。在时间、原因、条件、方式、让步等状语从句中，常常省略相同的主语或作主语的代词it以及be动词，保留现在分词、过去分词、介词短语、不定式等成分。如果从句中有“it is＋形容词”，也可以省略it is。
连词的考查主要集中在并列句和各种复合句中，主要考查连词的意义辨析。如：and, but, or或while以及其他连接名词性从句、定语从句和状语从句的连接词、关联词。
