1、状语从句 状语从句主要用来修饰主句或主句的谓语。一般可分为八大类, 分别表示时间、地点、原因、目的、结果、条件、让步、比较。尽管种类较多, 但由于状语从句与汉语结构和用法相似, 所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。 状语从句简介 时间状语从句 关联词 as /when / while; after; before; since; till / until ;as soon as ; whenever; no sooner than副词immediately; 名词短语the moment; the minute; the second

4、者均可表示“当的时候”, 如果主句表示的是短暂的动作, 而从句表示的是一段时间, 三者可通用。 as和when都可与终止性动词连用, while 只能与延续性动词连用。如： It was snowing _ we got to the airport当我们到达机场时, 天正下着雪。（不能用 while） 疑点解释 as强调主句与从句表示的动作同时发生; while强调主句表示的动作持续于while所指的整个时间内; when可指主、从句所述动作同时或先后发生。如: He sang as he went along. 他边走边唱.

9、一般放在句首。如： 常用引导词: _, _, _because since as6. 原因状语从句 Why cant I go? 为什么我不能去? _ youre too young. 因为你年纪太小了。 As (_)you are not feeling well，youd better stay at home 既然你不太舒服，还是留在家里的好。 常用引导词:_ _, _ _ _.so that in order that The boss asked the secretary to hurry up with the letters _ _ he could sign them.
