PAGEPAGE6专题04重点语法复习：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。考点四：让步状语从句让步状语从句的引导词有though/although，eventhough/if等。注意：though/although与but不能同时出现在一个句子里。如：Thoughheisinpoorhealth,heworkshard.虽然他身体不好，但是他工作很努力。考点五：比较状语从句比较状语从句的引导词有as…as，than等。如：Peterisnotastallashisbrother.彼得不像他哥哥那么高。考点六：结果状语从句结果状语从句的引导词有so/such…that…等。（1）区分两种句式：①so+adj./adv.+that…②such+(a/an)+adj.+n.+that…如：TomissocleverthathelearnsChinesewell.=TomissuchacleverboythathelearnsChinesewell.汤姆如此聪明，语文学得很好。（2）注意：当名词前有much，many，little，few等词修饰时，只能用so。如：Youcan’tspendsomuchtimeoncomputergames.你不能花这么多时间在网络游戏上。考点七：目的状语从句目的状语从句的引导词有sothat，inorderthat等。如：Hestoodupsothat/inorderthathecouldseetheblackboardclearly.他站起来，以便能清楚地看到黑板。注意：目的状语从句中一般都含有表示可能性的词语，如coule,will,would,can等。考点八：方式状语从句方式状语从句的引导词有as。如：Studentsdoastheteacherssay.同学们按照老师说的去做。考点九：地点状语从句地点状语从句的引导词有where，wherever等。如：I’dliketogowheretheairisveryfresh.我想去空气清新的地方。状语从句精练精析1．I’llgivehimyourmessage________hecomesbackfromlunch.A．until
