ck.十点钟前我就得上床睡觉。(1)haveto表示“必须,不得不”的意思,表示客观的需要,后接动词原形。donthaveto表示“不必”。,(2)haveto,hasto,hadto的疑问句和否定句要使用借助词do,does或did如:-Whatdowehavetodo?我们必须做什么事?-Youhavetofinishyourhomework.你们必须完成作业。,-Doyouhavetocomehereby8:00tomorrow?你们明天八点钟之前必须赶到这里吗?-Yes,wedo.是的。-Doesshewashalltheclothes?她必须洗所有的衣服吗?-No,shedoesnt没有必要。,(3)beinbed“卧床”,“睡觉”。如:Hewasinbedalldayyesterday.他昨天一整天都没有起来。(4)by在此句中为介词,意思是notlaterthan“最迟在”。如:Illbebackby6oclock.我最迟六点钟回来。,l.Itsnotsodifficult,Mr.Green.Iwant_.-Comeon,please.A.tryB.agoC.startingD.tohappen,Exercises,Choosethecorrectanswers.,本题主要考查go作为名词的用法。由题意可知“我认为这件事不难做,想试一试”。词组wantago就有“要试一试”的意思，go是名词。如果A项在try前加不定冠词a也正确。C、D两个选项句意不通。故选B。,2.Dont_theballlikethat.A.throwB.tothrowC.throwsD.throwing本题考查的是祈使句的否定式,其否定式Dont后面一定要接动词原形,因此只有A项正确。,3.Mikeis_hisnewball.A.playwithB.playingC.playingwithD.playplaywith玩玩具、玩艺儿。但“踢足球、打排球”不能使用这一句式,而只能用playfootball和playvolleyball,4.Lookatthatpictureonthewall._youlikeit?A.DoB.CanC.CouldD.Are句中like应理解为“喜欢“,是动词,构成疑问句时,要在句首加助动词比Do(Does用于第三人称)。动词like不与情态动词can、could连用。like与be动词连用时是介词,作“像一样”解、故D项不合句意。选,5._picturebookinclass,please.A.NotreadB.NoreadC.NotreadingD.DontreadD本题主要考查否定祈使句的用法。本祈使句的结构为“行为动词+宾语+其他成分”,在变否定句时,应在行为动词read前加Dont.故选D。,6.Thatphotoisveryold.Icantsee_colour.A.itB.itsC.itsD.a从句意看出所给的词要修饰名词colour。特指那张照片的颜色,不能用不定冠词,D项舍去。修饰名词需用形容词性的物主代词,A、C项也舍去,答案为B。,7.-Aretheymendingtheircars?-_.A.Yes,theyarentB.No,theyarenotC.Yes,theyareD.No,theyare,现在进行时回答要用简略式;即Yes,theyare,或No,theyarent.答案是肯定的用Yes,theyare.否定的用No,theyarent.不能用Yes,theyarent.或No,theyare.的形式。,8.-Hi,Mike.Theresanewfilminourschoolthisevening.-_!A.OKB.RightC.CertainlyD.Great第一个人报告了一条好消息,第二个人听了很高兴,通常说Great!意思是:棒极了
