Unit4MyFavouriteSubject连词and,but,because含义连词是一种虚词，不能单独充当句子成分，在句中只起连接作用。连词分为并列连词和从属连词两种。并列连词是连接彼此并列关系的词。从属连词是用来引导从句的词。and1.作并列连词，意为“和、又、及”可以连接并列的单词、短语或句子；意为“那么，于是“时，可根据具体语境进行翻译，也可不译，起承上启下的作用。Ilikeapplesandoranges.ehereandyoucanhaveagoodtime.Thisisanapple.Andwhat'sthat?2.在否定句中要把and变为or。Ilikeapplesandoranges.(改为否定句)Idon'tlikeapplesororanges.but表示转折关系，意为“但是、可是”。连接两个并列的成分或句子时，语气较强，在意义上构成明显的对比。与前半句可用(可不用)逗号分开，与后半句不用逗号分开。Thewomanisold,butshelooksveryyoung.(与前半句可用逗号分开)Mikehasabasketballbuthedoesn'thaveabaseball.but与and辨析but为转折连词，意为“但是”，连接两个并列的成分，表示前后意义的转折或两种情况的对比.Ourroomissmall,butit'sverytidyAnd为并列连词，意为“和；又；而”，连接并列的单词、短语或句子，表示顺承或并列关系。连接两个名词或代词作主语时，若指两人或两物，谓语动词用复数形式。Hecanplaytheguitarandhecansing,toobecause1.because属于从属连词、用于回答why引导的特殊疑问句，后跟句子，申述原因或由.Whyareyoulate?BecauseIgetuplate.2.引导原因状语从句，表示直接原因，原因构成句子的最主要部分。BecauseIgetuplate,Iamlateforclass.注意because(因为)与so(所以)不能同时出现在一个句子中。其它常用连词so所以；因此，并列连词,表示因果Igetuplate,soIamlateforclass.or或者并列连词,表选择Wouldyoulikecoffeeortea?both……and两者者并列连词,Ilikebothsportsandmusic.时间介词at1.接具体的时刻.Igetupatsixinthemorning.atnight和atnoon是固定用法.2.后还可以接假期.如:atChristmas,atSpringFestivalin1.后面主要接世纪、年、月、季节，或泛指一天的早上/上午、下午晚上等。如:inNovember;inthemorning2.接时间段,用在将来时态,表示“某段时间后”。Theywillebackintwodayon后面主要接星期几和具体某一天或某一天的早上/上午、中午、晚上等。IgotoschoolonMonday.OnSundaymorning,wewenttothecinema七上英语语法每日一练Day7Unit4连词and,but,because一、用适当的连词填空(40分)1.Ilikereading,mysisterlikesreadingtoo.2.Theywanttogoswimming,itistoohot.3.Thecountrysideissonicequiet.4.Theyareverybusythisafternoontheycan'tetoyourbirthdayparty.5.MyMumwilletosee,shewillbringmesomethingnice.6.Ican'twatchTV,Ihavetoomuchhomework.7.I'mbusytoday,Ican'tgooutwithyou.8.Thisismypen,thatisyourpencil.9.Mymomthinksthedressisnice,itdoesn'tlookgoodonme.10.Heistall,hisbrotherisshort.二、单项选择(40分)()1.Ican'tcallMissGreenIdon'tknowhertelephonenumber.A.and B.butC.because D.so()2.IwanttolearnEnglishwell,Ilistentotheradioeverymorning.A.SoB.or C.but D.for(3.Why3.Whydoyoulikethisbook?it'sgreatfun.A.Because B.SoC.And D.But()4.GinaandLisaaregoodfriends,theyaren'tmyfriends.A.always B.but C.too D.for()5.Iliveclosetothelibrary,Iusuallygothereonfoot.A.and.B.because.C.so D.but()6.MrWangisverytired,hegoestobed.A.andB.orC.but D.so()7.Theboyhurthimselfheclimbedthetreeandthenfelloutofit.A.because B.before C.ifD.until()8.theteachersareallveryniceandhelpfulllikemyschoolverymuch.A.Becạuse;so,B.Although;butC./;becạuse D./;so()9.Ican'tplaywithAlan,Ihavealotofworktodo.A.SoB.because C.butD.and()10.IlikeEnglishit'sveryinteresting.A.or B.but C.so D.because三、按要求改写句子(20分)1.Ilikeapplesandoranges.(改为否定句)Ourroomissmall.Ourroomistidy.(将两句话合并成一句话)Heisverykindsomanypeoplelikehim.(用because改写句子)Sheishappybecauseshepassedtheexam.(对画线部分提问)Ilikestrawberriesandbananas.(用or改为选择疑问句)Igotobedattenatnight.(对画线部分提问)Ican'tgotothepartybecauseIambusy.(对画线部分提问)Iamlateforclass,becauseIgetlate.(用so改写句子).Chocolateisn'thealthy.It'smyfavouritefood.(用but连接两个句子)Hecanplaytheguitar.Hecansing(用and连接两个句子)第4单元每日一练答案Day7一、1.and2.because3.and4.so5.and6.because7.so8.and9.but10.but二、15:CAABC610:DADBD三、1.Idon'tlikeapplesororanges.2.Ourroomissmall,butit'sverytidy.3.Manypeoplelikehimbecauseheisverykind.4.Whyisshehappy?5.Do
