Module 8语法篇____________________________________________________________________________________________________________________________________________________________________熟练掌握本模块语法知识。语法：when，while，as引导时间状语从句的区别?when，while，as都可以引导时间状语从句，但用法区别非常大。??一、when可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用。??①?Why?do?you?want?a?new?job?when?you’ve?got?such?a?good?one?already？（get为短暂性动词）你已经找到如此好的工作，为何还想再找新的？??②Sorry，I?was?out?when?you?called?me．（call为短暂性动词）对不起，你打电话时我刚好外出了。??③Strike?while?the?iron?is?hot．（is为延续性动词，表示一种持续的状态）趁热打铁。④?The?students?took?notes?as?they?listened．（listen为延续性动词）学生们边听课边做笔记。??二when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生。??1．从句动作在主句动作前发生，只用?when。??①When?he?had?finished?his?homework，he?took?a?short?rest．（finished先发生）当他完成作业后，他休息了一会儿。????从句动作和主句动作同时发生，且从句动作为延续性动词时，when，while，as都可使用。①When?／While?／As?we?were?dancing，a?stranger?came?in．（dance为延续性动词）当我们跳舞时，一位陌生人走了进来。??②When?／While?／As?she?was?making?a?phone?call，I?was?writing?a?letter．（make为延续性动词）当她在打电话时，我正在写信。??当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用?as。这时，as常表示“随着??”；“一边??，一边??”之意。??①?As?the?time?went?on，the?weather?got?worse．（as表示“随着??”之意）??②?The?atmosphere?gets?thinner?and?thinner?as?the?height?increases．随着高度的增加，大气越来越稀薄。??③As?years?go?by，China?is?getting?stronger?and?richer．随着时间一年一年过去，中国变得越来越富强了。??④The?little?girls?sang?as?they?went．小姑娘们一边走，一边唱。??⑤The?sad?mother?sat?on?the?roadside，shouting?as?she?was?crying．伤心的妈妈坐在路边，边哭边叫。1.—Hi,Lin Tao,I didn’t see you at the party.—Oh,I______ready for the maths exam.A.am getting　　　　　　B.was gettingC.gotD.have got2.—Hello,you look tired today.—Yes,I slept too late yesterday evening.
