Growingup一教学目标知识目标1.学会使用时间状语从句的连接词‘since,till,untilassoonas,whenever.能力目标1.能运用恰当的时间连词谈论生活；二教学重难点如何用恰当的时间连词谈论生活三学习与交流A.since,till和until常用来引导时间状语从句。Eg:MrBrownhasbeeninBeijingsinceyouleft..(1)since表达“自从--以来”。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。如：Theyhavebeenfriendssincetheywereinprimaryschool.他们从小学起就一直是好朋友。【拓展】since的其他用法：1.since后可接具体的过去的时间点，或者一段时间+ago.句子使用现在完成时态。如：eg:Themanhasworkedheresince2012.自从2012年这个人一直在这里工作。2.itis+一段时间+since+一般过去时从句eg:Itisthreedayssincetheycametoshanghai.他们去上海三天了。Eg:Itisthreeyearssincehisgrandfatherdied.他爷爷死了三年了。B．till和until表达“到---为止”，一般情况下两者可以互换。Until可以放在句首或句中，而till只用于句中，不能用于句首。【注意】：如果主句的谓语动词是瞬间动词时，必须用否定形式，即“not---until”结构，表达“直到---才”，如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以。如：Eg:Ididn’tgotobeduntilIfinishedmyhomework.Eg:Istudieduntil12o’clocklastnight.c.assoonas和whenever引导的时间状语从句(1)我们常用assoonas和whenever引导时间状语从句。如：AssoonasIarriveinCanada,Iwillringyouup.我一到加拿大，就给你打电话。(2)assoonas表达“一-----就”。如：Webegantoworkassoonaswegotthere.我们一到那儿就开始工作。(3)whenever表达“每当，任何时候”。如：Helikeslisteningtomusicwheneverhehastime.每当他有时间的时候，他喜欢听音乐。【注意】whenever还可以用everytime或者nomatterwhen替换。四典型题例()1.(2013重庆中考)I’llgotovisitmyauntinEngland________thesummerholidaysstart.A.whileB.sinceC.untilD.assoonas()2.---Jimmy,it’stimetogotobed.---Oh,Iwon’tdothat_________Ifinishmyhomework.A.ifB.untilC.afterD.when()3.Tenyearshaspassed________theCCTVeventPeopleWhoMovedChina（感动中国）tookplacein2002.A．whenB.whileC.beforeD.since()4.—Whenwillyoufinishthework?---Iwon’tfinishituntilI___________tenmoreminutes.A.giveB.willgiveC.amgivenD.willbegiven()5.—Hurryup!Thebusiscoming.---Waitaminute.Don’tcrossthestreet______thetrafficlightsaregreen.A.afterB.untilC.whileD.since()6._________youhaveachancetospeakEnglish,youshouldtakeit.A.WhateverB.HoweverC.WheneverD.WhileI.词汇1.PeterandSimonenjoyed_____________(they)attheEnglishpartylastnight.2.HereturhedtoChinawheneverhe________________(need)byhiscountry.3.Iwon’tgotobeduntilIfinish_____________(watch)myfavouriteTVprogramme.4.Danieliscrazyabout___________(play)computergames.5.Itismyfirsttime___________(visit)theGreatWall.6.Lilyspendslotsoftimepracticing_____________(speak)Englisheverymorning.7.Weshouldtryourbest___________(learn)Englishwell.8.AftermybrotherwenttotheUSA,helearntEnglish____________(quick).9.Assoonashe___________(come),Iwillletyouknow.10.MrWu_____________(teach)Englishinthatschoolsincehe__________(come)here.II.单项选择()1.—HowwasyourclimbingMount,Huang?---Ididn’tbelieveIcoulddoit__________Igottothetop.A.untilB.whileC.afterD.since()2.—Willyoutellheraboutthenews?---Sure,I’lltellheraboutitassoonasshe_______back.A.comeB.willcomeC.cameD.comes()3.She_______untilhecamebackfromwork..A.waitedB.didn’twaitC.wentoutD.left.()4.MysisterhaslearntEngish______________.A.fortwelveyearsagoB.sinceshewasfourC.twelveyearsagoD.attheageoffour()5.Ifyouhavedifficultypronouncingthesewords,youcanrepeatthemoverandoveragain_______...
