if/unless引导的条件状语从句。
until/when/while/as soon as引导的时间状语从句。
because引导的原因状语从句，so that引导的目的状语从句等。
if引导的条件状语从句和when引导的时间状语从句一般都会和时态相结合，即主要考查“主将从现”原则。
对于状语从句的学习可与专题六从属连词相结合。
在时间状语从句和条件状语从句中，主句和从句的时态一致问题一般有两种情况：（1）“主将从现”：主句用一般将来时，而从句用一般现在时。
常见的使用“主将从现”原则的连词有：表示时间的when, while, after, before, until, till, whenever, as soon as, as long as, once 等；表示条件的if, unless, so long as, in case等。
（2）“主祈从现”：若主句是祈使句，或主句中有情态动词时，那么从句用一般现在时表示将来。
（3）“主情从现”：若主句有情态动词, 那么从句用一般现在时表示将来。
如：You can get good grades if you study hard.如果你努力学习，你将取得好成绩。
状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,其前一般不用逗号。
状语从句根据其用途可分为时间状语从句、条件状语从句、原因状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、地点状语从句等。
二、时间状语从句(1)当主句是一般将来时态或祈使句,表示将来的意义时,从句通常用一般现在时,简称“主将从现”。
I’ll ring you up as soon as I get to Beijing.我一到北京就给你打电话。
(2) when引导的时间状语从句,通常表示主句和从句的动作同时发生;before表示主句的动作发生在从句的动作之前;after则表示主句的动作发生在从句的动作之后;as引导时间状语从句时,往往表示主句和从句的动作同时发生,不分先后。
