初中英语语法专题 : 状语从句 讲解与练习(PDF版)

状语从句在英语中,状语从句在主从复合句中修饰主句中的动词、形容词或副词等。
状语从句由从属连词引导,与主句连接,位于句首时,常用逗号分开,位于句末时,其前一般不用逗号。
英语中的状语从句根据其用途可分为九大类,分别可表示时间、地点、原因、目的、结果、条件、让步、比较和方式。
学习状语从句关键是要掌握引导九类状语从句的有关连接词。
只要记住连接词一般都能识别是何种状语从句,从而正确分析句子结构并理解句子意思。
一、时间状语从句引导时间状语从句的连词较多,但它们的共同点是:当主句是一般将来时或祈使句表示将来的意义时,时间状语从句用一般现在时(主将从现)。
例如:I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.时间连词when 的用法一般来讲,when 的意思相当于at that time (在……时刻),从句的谓语动词通常是短暂动词,表示某一时刻的动作。
不过,when 引导的从句也可接延续动词,这时从句往往用过去进行时态,表示某一时间段内发生的动作。
时间从句所表达的时间通常是过去和将来。
常见表示过去动作的四组时态搭配:一、主句一般过去时+从句一般过去时I started my dinner when he left.He left when I got there.二、主句一般过去时+从句过去完成时I started my dinner when he had left.He left when I had got there.三、主句一般过去时+从句过去进行时(三、四用法见过去进行时“长动作,短动作”)The doorbell rang when I was telephoning.副词从句种类常用连接词时间状语从句when,while ,as,before ,after ,since ,till ,until ,as soon as 地点状语从句where 原因状语从句because ,as,for,since 目的状语从句so that ,in order that 结果状语从句so...that,so that,such...that 条件状语从句If,unless 让步状语从句although,though,even though,even if 比较状语从句as,than 方式状语从句as,the way四、主句过去进行时+从句一般过去时I was telephoning when the doorbell rang.时间连词while的用法while用作时间连词时,意思相当于during that time(在……期间),表示某一时间段内发生的动作。
