第07讲 预习九上：时间、条件和原因状语从句（原卷版）-【暑假自学课】2023年新九年级英语暑假课（牛津译林版）

第页第07讲预习九上：时间、条件和原因状语从句掌握并正确使用时间状语从句、条件状语从句和原因状语从句在复合句中，做状语成分的从句叫状语从句。常见的状语从句可分为：时间、条件、地点、原因、方式、让步、比较、结果、目的等从句，由不同的引导词引导。考点一：时间状语从句引导词用法例句whenwhen引导的时间状语从句中既可接延续性动词，也可接非延续性动词，多用一般过去时TheyweretalkinghappilywhenIwalkedpastthedoor.当我从门前走过，他们正在开心地聊天。whilewhile强调主句和从句动作同时发生，所引导的时间状语从句只能用延续性动词，多用进行时态。MymotherwascookingwhileIwasdoingmyhomework.当妈妈在做饭的时候，我在做作业。not…until主句的谓语动词为非延续性动词，主句要用否定式，从句用肯定式。Thebuswon’tstartuntileverybodygetson.公共汽车直到每个人都上车才会发动。since主句谓语动词一般用现在完成时，从句谓语动词一般用一般过去时。Fiveyeashaspassedsincewesaweachotherlasttime.距离我们上次见面已经五年过去了。beforebefore引导的从句表示主句的动作发生在从句动作之前。Weturnedoffthelightbeforeweleft.我们在离开前关了灯。afterafter引导的从句表示主句的动作发生在从句动作之后。Hewenttobedafterhefinishedhiswork.他做完工作后就去睡觉了。assoonas若主句为一般将来时，从句常用一般现在时表将来。IwilltellhimthenewsassoonasIseehim.我一看见他，就会告诉他这个消息。考点二：条件状语从句条件状语从句的引导词主要有if和unless，两者可转换。在条件状语从句中，从句常用一般现在时表将来，即主将从现。如：Youwillfailtheexamifyoudon’tworkhard.=Youwillfailtheexamunlessyouworkhard.如果不努力学习，你考试会不及格的。考点三：原因状语从句原因状语从句的引导词有because，since，as等。注意：1.because和so不能同时使用。如：Hedidn’tcometoschoolyesterdaybecausehewasill.他昨天没来上学，因为他生病了。2.since引导原因状语从句表示显然的或已为人知的理由，表示“因为，既然”如：sinceeveryoneishere,let’sstart.既然大家都到期了，我们就开始吧。考点一：时间状语从句1．（2022秋·辽宁沈阳·九年级沈阳市第一二六中学校联考期末）Mr.Brownhasworkedinthisschool________hewas22yearsold.A．for
