CBCCD状语从句的省略一般说来省略现象多出现在下列五种状语从句中：由 when,while,as,before,after,till,until,once 等引导的时间状语从句;由 whether,if,unless 等引导的条件状语从句;由 though,although,even if,whatever等引导的让步状语从句;由 as,than 等引导的比较状语从句;由 as,as if,as though 等引导的方式状语从句。上述状语从句在省略时，并非任何成分都可以省略而是遵循下面原则：(1)当状语从句的主语与主句的主语一致时，可以省略状语从句的主语和系动词be，这时从句中可出现如下结构：连词(as,as if,once)+名词如：Once(he was)a worker,Pang Long now bees a famous singer.庞龙曾经是个工人，现在变成一位著名的歌手。连词(though,whether,when)+形容词如：Work hard when(you are)young,or youll regret.趁年轻要努力学习，要不然你会后悔的。连词(whether,as if,while)+介词短语如：He looked everywhere as if(he was)in search of something.他到处看似乎在找什么东西。连词(when,while,though)+现在分词-可修编-.如：While(he was)holding talks with President Hu Jintao,US President George W.Bushthanked China for its important role in the Six-Party Talks.美国总统布什在与主席会谈时，感中国在六方会谈中起的重要作用。连词(when,if,even if,unless,once,until,than,as)+过去分词如：The exhibition is more interesting than(it was)expected.这次展览比被预料的有趣的多 连词(as if,as though)+不定式如：Olympic gold medallist hurdler Liu Xiang opened his lips as if(he were)to speak.奥林匹克金牌获得者跨栏运动员翔开嘴好象要说什么。(2)当从句的主语是 it，谓语动词中又含有系动词be 时，可以把 it 和系动词 be 一起省略。此时构成连词(if,unless,when,whenever)+形容词的结构。如：Unless(it is)necessary,youdbetter not refer to the dictionary.如果没有必要，你最好不要查字典。各种状语从句的省略现象列举如下：一、时间状语从句中的省略一、时间状语从句中的省略When(she was)very young,she began to learn to play the piano.她很小时，就开始学习弹钢琴。While(I was)at
