状语从句讲练
通常用来说明主句中某一动词、形容词、副词等的起状语作用的从句,叫做状语从句,状语从句按意义和作用可分为以下几类:
一、时间状语从句:连接时间状语从句的连接词有: when, while, as如果主句和从句的动作同时发生且都是进行时态,多用while, as,其他情况下三者可通用。before, after, since, until(till) as soon as通常情况下,主句用一般将来时,时间状语从句中多用一般现在时。
二、地点状语从句: 连接地点状语从句的连接词有:where, wherever=no matter where:
Where there is a will, there is a way.

三、原因状语从句:连接原因状语从句的连接词有:because, as, since, for等。
