take more care, you’ll have an accident.如果不多加小心的话,你会出事故的。Mybaby sister never cries unless she is hungry.我那刚出生的妹妹除非饿了,否则她是从来不哭的。\nDon’t promise anything unless you’re 100 percentsure.不要作任何的许诺,除非你有百分百的把握。Unlessbad weather stops me, I jog every day.(除非坏天气作梗,每天我都慢跑。)误:Don’tcomeinunlessyouwillbeinvitedto.正:Don’tcomeinunlessyou’reinvitedto.误:Unlesshewillcome,wewon’tbeabletogo.正:Unlesshecomes,wewon’tbeabletogo.\nAssoonas的用法英语动词的时间大致可分为三段:过去时、现在时、将来时。假设有两件事A和B,就会出现三种情况:A过去时assoonasB过去时A现在时assoonasB现在时A将来时assoonasB将来时\n在每一个大的时间段内,A和B的时态要统一。比如A过去时,B肯定在过去时内。其它也是如此。至于在每个大时间段内,再根据A和B两件事的具体情况,具体对待。比如:A和B都是过去时,A和B是同时发生,还是先后发生,不是即将发生,再分别选用完成时、进行时、将来时。例如:\nA过去时B过去时:IarrangedtheflowersinthevaseassoonasIcamebackhome.一回到家里,我就把花在花瓶里插好。A过去进行时B过去完成时(虚拟)Hewasshakingwithfrightasifhehadseenaghost.他吓得直哆嗦,就好像看见了鬼一样。\nA将来时B将来时(可用一般现在时表达)Theywillpostmethetickets/posttheticketstomeassoonastheyreceivemycheque.他们收到我的支票后就立刻把票寄给我。\nassoonas连接的时间状语从句中,指未发生的动作。规律是:主句一般将来时,从句用一般现在时代替一般将来时。如:Iwilltellhimthenewsassoonashecomesback.紧接着发生的两个短动作,主从句都用一般过去时。如:HetookouthisEnglishbooksassoonashesatdown.\nso....that....如此……以致于……(that引导的结果状语从句)so的后面跟副词或形容词,例:老师说的太快了,以至于我听不清楚他的话。TheteacherspeakssofastthatIcan’tcatchthewords.so…that…的用法\n[比较]so…that…与sothatSothat:(1)引导结果状语从句,意为“因此,所以”,主句和从句间常用逗号分开,一般不与情态动词连用。Nothingmorewasheardofhim,sothatpeoplethoughtthathewasdead.未再听到他的消息,以致人们认为他已死去了。\n(2)引导目的状语从句,意为“为了,以便”,通常从句中用may,might,can,could等情态动词。Weleftearlysothatwecouldcatchthefirstbus.我们很早出发,以便能赶上第一班汽车。\n1.____________herfatherdied,thestepsistersmadeherdoallthechores.2.Shewas____busy______shehadnotimetomakeadressfortheparty.3.Themiceknewthat___________theyhelpedhermakeadress,shewouldnotbeabletogototheparty.Fillintheblankswithunless,assoonasorso...that.Assoonassothatunless4a\n4.___________theprincesawher,hefellinlovewithher.5.Theprinceknewthat_________thegirl’sfootcouldfittheshoe,itwasnottherightgirl.6.Thenewcouplewere____happy______theycouldn’tstopsmilingwhentheygotmarried.unlesssothatAssoonas\nTheMonkeyKingisthemaincharacterfromthefamousChinesestoryJourneytotheWest.Heiswonderfulbecausehe______(help)weakpeople.TheMonkeyKing_____(have)amagicstick.He_____(use)ittofightbadpeople.Hecan______(make)thestickbigorsmall.HecansometimesFillintheblankswiththecorrectformsoftheverbsinbrackets.helpsusesmakehas4b\nmakethesticksosmallthathecanputitinhisear.Assoonashe______(see)badpeople,hethinksofwaystofightthem.Hecan_______(turn)himselfintodifferentanimalsandobjects.Butunlesshecanhidehistail,hecannotmakehimselfahuman.Childrenallovertheworld______(love)theMonkeyKing!seesturnlove\nTellyourpartneraboutyourfavoritestory.Myfavoritestoryis...Itisinterestingbecause…4c\nI.用适当的连词填空。1.______itrains,I’llgotoschoolbybus.2.Iwilltellyouthesecret_____youdon’ttellanyoneelseaboutit.3.Maryalwaystakesaseatinthefirstrow________shecanhearbetter.4.We_______noticeanythingwrongwiththecomputer_______westartedusingit.Ififsothatdidn’tuntilExercises\n5.Mymotherwasworried__________itrained.6.Theelephanthas______strongabody______itcandoheavywork.7.Itis__________difficultproblem__________nobodycanworkitout.becauseathatsuchsothat\n他努力学习,以便取得好成绩。Heworkshard_______hecangetgoodresult.2.老师写得很仔细,是为了让我们看得清楚。Theteacherwrotecarefully________wecouldseeclearly.sothatsothatII.用so…that…填空。\n3.他太伤心了,以致说不出一个字来。Heis_____________hecan’tsayaword.4.妹妹身体太弱了,不能再走了。Mysisteris______________shecan’twalkfarther.sosadthatsoweakthat\nIII.句型转换。1.Useyourhead,thenyou’llfindaway.=____youuseyourhead,you’llfindaway.2.Iwenttobedaftermyfathercamebackhomeyesterday.=I_______gotobed______myfathercamebackhomeyesterday.Ifdidn’tuntil\n3.Theislandissobeautifulthatitcanattractlargenumbersofpeople.=Theislandis_______________________attractlargenumbersofpeople.4.MydressismoreexpensivethanLily’s.=Lily’sdressis_____________________mine.beautifultonotas\soexpensiveasenough\nIV.用所给词的适当形式填空。1.
