Artworld一、教学目标能理解并运用原因壮语从句二.教学重点:原因壮语从句三,交流展示Since与as引导的原因壮语从句(1)我们也可以用Since与as引导原因状语从句。如:Sinceyouarefree,youhadbettertidyyourbedroom.既然你用空,你最好把卧室整理一下(2)Since表达“既然,由于,因为”表示已知的,显然的理由,较为正式。常放在句首。如:Sinceitislate.Ishallgohomerightnow.由于时间不早啦,我得回家啦。(3)As与since的用法大体相同,表示附带说明的是双方已知的原因。如:Asitisraining,youhadbettertakeataxi.既然在下雨,你最好乘坐出租车。友情提醒:Since与as引导的原因状语从句最好放在句首。Because,since与as(1),关于Because:语气最强,表示直接原因,可以回答why提出的问题,引导表语从句,用于强调句子等,其余两者都不行。--Whydidn’thecome?他为什么没来?--Becausehewasill.因为他生病了。(2)关于Since与as:两者表示的原因都是人们已知的,即对已知事实提供理由,而不是表示直接原因。Since比as语气稍强,而且比as略为正式,他们引导的从句通常放在主句之前,有时也放在主句之后:Areyouwerenotthere,Ileftamessage.由于你不在那儿,我留了个口信。Since可用来省略句,而其他两者不可以。Sinceso,Ihavenothingtosay.既然如此,我无话可说。五.当堂检测。I.选择填空。()1.Mikewasillyesterday,_____________hedidnotgotoschool.A.ifB.butC.soD.because()2.Tonyneverspendsmoneyonbuyingbooks___________hedoesn'tlikereading.A.butB.becauseC.thoughD.until()3.MoYan'sbookshavebeensoldoutinmanybookstores___________hiswinningoftheNobelLiteraturePrize.A.becauseB.sinceC.asD.becauseof()4.Thefamilyhadtostayatthehotel,___________itwasraininghard.A.becauseB.althoughC.untilD.unless()5.--WhydoyoulikethisTVprogram?_________it'sveryinterestingandexciting.A.ThoughB.BecauseC.So()6.BecauseIgotupverylatethismorning,___________Iwaslateforclass.A.butB./C.so()7.Sinceyouaretired,youhadbetter____________andhaveagoodrest.A.stoptostudyB.stopstudyC.stopstudyingD.stoptostudying()8.________________everyoneishere,let'sbeginourmeeting.A.ThoughB.SinceC.BeforeD.So()9.WecantalkwithfriendsontheInternet._________it'seasierandcheaper.A.thoughB.asC.orD.butII.选词填空。l.Doyouthinkthebestmusic____________nature?2.Let'sgooutfora_____________offreshair.3.It's_____________possiblethatourteamwillwinthematch.4.Sandy_____________dancing,soshewilldanceattheparty.5.Howlongwillthebadweather_______________?III.用给词的适当形式填空1.Yangzhouliesinthe___________(centre)partofJiangsuProvince.2.Everyoneofthe__________(win)willreceiveaprize.3.Chinais____________(know)forherlonghistory.4.Obviously,hefeelslike____________(control)thecompany.5.ThescientistsfromtheUKwerethefirstto_________(success)cloneananimal.6.Wemustbring___________(tradition)ChinesemedicineandmodernWesternmedicinetogether.六、教学反馈(反思)学生反馈:教师反思:highly,breathe,last,isgoodat,comesfrom
