8、sif,asthough 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,asif,once)+名词女口： On ce(hewas)aworker,Pa ngLongno wbecomesafamouss in ger.庞龙曾经是个工人，现在变成一位著名的歌手。连词(though,whether,when)+形容词女口： Workhardwhen(Rouare)Roung,orRoullregret.趁年轻要努力学习，要不然你会后悔的。连词(

9、whether,asif,while)+介词短语女口： HelookedeverRwhereasif(hewas)insearchofsomething.他到处看似乎在找什么东西。连词(when,while,though)+现在分词如：While(hewas)holdi ngtalkswithPreside ntHuJi ntao,USPreside ntGeorgeW.Bushtha nkedChi naforitsimporta ntrolei ntheSiR-PartRTalks.美国总统布什在与胡锦涛主席会谈时，感谢中国在六方会谈中起的重要作用。连词(when,if,evenif,un

11、的结构。如：Un less(itis )n ecessarR,Roudbetternotrefertothedictio narR.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When(shewas)verRRoung,shebegantolearntoplaRthepiano.她很小时，就开始学习弹钢琴。While(Iwas)atcollege,Ibega ntok no whim,astra ngebutablestude nt.我在上大学时就开始认识他，一个奇怪但有能力的学生。When arrivi ng,se ndmeatelegram.(W
