Unit5ArtworldGrammarPreviewbecauseSinceAsGivingreasonswithbecausePartAWhatisaclauseofreason?原因狀語從句是指在復(fù)合句中表示主句動作發(fā)生的原因的句子Weusebecausetointroduceclausesofreason.1.because意為“因為”，表示動作發(fā)生的直接原因，語氣很強。e.g.Ilikelisteningtomusicbecauseitmakesmefeelrelaxed.IlikepaintingbecauseIlikeallthedifferentcolours.2.

because可以用來回答why引導(dǎo)的疑問句。e.g.---Whydoesn’thegowithus?---Becausehe’stootiredtoday.3.在一個英語句子中，so和because不能同時出現(xiàn)。e.g.Becausemybikewasbroken,Iwalkedtoschoolyesterday.(√)

Becausemybikewasbroken,soIwalkedtoschoolyesterday.(×)4.becauseof也可表達直接的原因，后接名詞代詞或動名詞。一般情況下可以和because引導(dǎo)的從句互換。becausebecauseofbecausebecauseofDanielhasmorequestionsaboutTanDun.HesearchedtheInternetandmadesomenotes.Lookathisnotesandanswerhisquestions.Usebecausetointroducethereasons.1.WhywasTanDunchosentowritemusicfortheBeijingOlympics?____________________________________________________________2.WhydoesTanlikethesoundsofnature?____________________________________________________________3.WhyisTanabletobuildabridgebetweentheEastandtheWest?____________________________________________________________4.WhydopeoplethinkhighlyofTan’smusic?____________________________________________________________BecausehehassuccessfullybroughtChineseandWesternmusictogether.Becausehehascreatedanewtypeofmusic—musicwithoutboundaries.GivingreasonswithsinceandasPartBSince,asandforarealsousedtogivereasonsforsomething.1.since意為“因為，既然”，as意為“由于，鑒于”。相對于because而言，since和as的語氣較弱。since和as的用法大體相同，表示附帶說明的“雙方已知的原因”。由這兩個詞引導(dǎo)的原因狀語從句通常位于句首。e.g.Sinceitislate,Ishallgohomerightnow.Asitisraining,you’dbettertakeataxi.2.for屬于并列連詞，不是說明直接原因，而是對某種情況加以推斷或解釋，對前一分句進行附加說明。由它引導(dǎo)的分句通常只能置于句末，且必須用逗號與前面的分句隔開。e.g.Hemusthavepassedthisway,forherearehisfootprints.Theremustbenooneinthehouse,forthedoorisclosed.ThereisgoingtobeanartfestivalatSunshineMiddleSchool.HelpAmymakesentenceswithsinceoras.1.Danieldecidedtoplaytheviolinattheartfestival.Heisgoodatit.______________________________________________________________________________________________________________________2.Kittywilldanceatthesonganddanceshow.Shehastopractisehardthesedays.______________________________________________________________________________________________________________________3.Sandywilldesignthepostersfortheartfestival.Shecandrawverywell.______________________________________________________________________________________________________________________Danieldecidedtoplaytheviolinattheartfestivalsince/asheisgoodatit.Since/AsKittywilldanceatthesonganddanceshow,shehastopractisehardthesedays.Sandywilldesignthepostersfortheartfestivalsince/asshecandrawwell.Since/Assomestudentslovepaintingandtakingphotos,therewillbeastudents’artshow.Ourschoolgaveusfreeticketstoanopera(1)________itcanhelpuslearnmoreaboutdifferentartforms.(2)________Milliealsoplannedtotaketheunderground,wewenttothetheatretogether.Whenwearrived,Kittyhadalreadybeenthere.SoonSimonandDanielcame.(3)________itwasstillearly,wewenttobuysomedrinks.“We’dbetterbequick(4)________theoperawillbeginin20minutes,”Kittysuggested.Wecamebackquickly.ThenwewaitedforAmyoutsidethetheatre.becauseSince/AsSince/Assince/asbecausebecauseSince/As1.“I’mlatebecausetherewastoomuchtraffic,”shesaid,outofbreath.breathn.呼吸；一次吸入的氣體breathev.呼吸；吸入outofbreath上氣不接下氣takeadeepbreath=breathedeeply深呼吸e.g.Weclimbedtothetopofthemountaininonebreathe.Takeadeepbreathwhenyou’renervous.Languagepoints2.Thenwehurriedintothetheatre.(1)hurryv.匆忙，趕快hurryup(withsth.)趕快，急忙(做某事)hurrytosp.匆忙趕往某地e.g.Hurryupwithyourfood,Sally.Hehurriestoschooleveryday.(2)hurryn.匆忙，急忙inahurry匆忙，急忙
