状语从句(adverbial clause)复习要点:掌握句法功能,记住连接词语法意义:状语从句是复合句中的一种,整个从句作主句的状语,修饰主句中的谓语动词、形容词、或副词。
置于句首时,状语从句后面一般要有逗号隔开;如果状语从句置于句尾,则从句一般不用逗号。
按照所作的状语和意义可分为时间、地点、原因、目的、结果、条件、让步、方式和比较等九种状语从句。
具体如下:一、时间状语从句(Adverbial Clauses of Time)时间状语从句通常由when,whenever,as,while,before,after,assoon as,since,once,no sooner...then,hardly/scarcely...when,tiLl/until 以及the moment,directly,immediately,the second,thefirst time,next time,every time,等引导。
1.由when,as,while 引导的状语从句:1)when 引导时间状语从句,表示当···,其谓语动词可以是延续性的,也可以是非延续性的,其作用最广泛。
