一 状语从句的种类 § 1状语从句的种类 用来修饰谓语动词、其它动词、定语、状语或整个句子的从句叫做状语从句。状语从句可分为: 1.时间状语从句;(adverbial clause of time) 2.地点状语从句;(adverbial clause of place) 3.原因状语从句;(adverbial clause of cause) 4.条件状语从句;(adverbial clause of condition) 5.目的状语从句;(adverbial clause of purpose) 6.让步状语从句;(adverbial clause of concession) 7.比较状语从句;(adverbial clause of comparison) 8.程度状语从句;(adverbial clause of degree) 9.方式状语从句;(adverbial clause of manner) 10.结果状语从句。(adverbial clause of result) §2状语从句的时态特点 一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”。例如: I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。(这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,决不可用will arrive) As soon as I have finished this work, I will go home. 我一完成此工作,就回家。(从句中的谓语动词用现在完成时have finished,表示将来完成时,决不可用will have finished) If he comes back, please let me know.如果他回来了,请通知我。(从句中的谓语动词用comes back,表示一般将来时,决不可用will come back) 二 时间状语从句 §3时间状语从句(adverbial clause of time) 1.由when, while, as引导的时间状语从句。例如: When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候,你就是在开始知道一些事物了。
简单点说 1)状语是副词性的 2)它可以修饰动词、动词短语、整个句子、形容词、形容词短语,也可以修饰副词 3)它可以有由副词、短语或句子来充当 4)位置非常灵活,可以安插在句前、句中或句后 举例说明: 1)I will love you till death do us part. (till death do us part,句子充当状语,修饰I will love you 这个主句) 2)You have done much better than before. (much,状语,修饰better) 3)I have promised for thousands of times that I will come back for you one day.(for thousands of times 状语,修饰have promised)
