初中祈使句练习

1祈使句（ImperativeSentence）一．定义用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此在学校文法中也常称为命令句。祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号来表示结束。.用客气的语气表示祈使句时，可在句首或句尾加上please，但如果在句尾加please，那在please之前一定要加一个逗号“，”。二、相关口令祈使句无主语,主语you常省去;动词原形谓语当,句首加don't否定变;朗读应当用降调。三、表现形式●肯定结构:1.Do型(即:动词原形(+宾语)+其它成分)。如:Pleasehaveaseathere.请这边坐。有的祈使句在意思明确的情况下,动词可省略。如:Thisway,please.=Gothisway,please.请这边走。2.Be型(即:Be+表语(名词或形容词)+其它成分)。如:Beagoodboy!要做一个好孩子!Bequite.安静Becareful！2小心！3.Let型(即:Let+宾语+动词原形+其它成分)。如:Letmehelpyou.让我来帮你。●否定结构:1.Do型和Be型的否定式都是在句首加don't构成。如:Don'tforgetme!不要忘记我!Don'tbelateforschool!上学不要迟到!2.Let型的否定式有两种:“Don't+let+宾语+动词原形+其它成分”和“Let+宾语+not+动词原形+其它成分”。如:Don'tlethimgo./Lethimnotgo.别让他走。3.有些可用no开头,用来表示禁止性的祈使句。如:Nosmoking!禁止吸烟!Nofishing!禁止钓鱼!四．反意疑问句，祈使句后可以加一个简短问句，使语气变得客气一些.如：Havearest,willyou.Standup,will(won't)you.注意：Let''sgo，shallwe？Letusgo，willyou？3祈使句练习一、将以下祈使句改为否定式：1.Comehereearly.2.Askhim.3.Pleasewaitforher.4.Readthebookcarefully.5.Situnderthetree,please.6.Let’sgotheretogether.二、选择最佳答案填空：()1.Ifyouaretired,______arest.A.haveB.havingC.tohaveD.had()2.Heisnothonest.______believehim.A.NotB.Don’tC.TonotD.Notto()3._____inthestreet.It’sdangerous.A.NotplayB.NottoplayC.Don’tplayD.Don’ttoplay()4.Please______mesomemoney,willyou?A.lendB.lendingC.tolendD.belend()5.Thefilmisabouttobegin.Please______seated.A.beB.areC.isD.being()6._____theboxes.Youmayusethemlater.A.KeepB.KeepingC.TokeepD.Kept()7._____upearlytomorrow,oryoucan’tcatchthetrain.A.GettingB.GetC.TogetD.Got()8.Herdoctorsaid:“________worksohard”AStopBDon’tCCan’tDNo()9.Sindy,________tobehereat8o’clockAissureBdosurethatCwillbesureDbesure()10.________himthesecret,willyou?A.Don’ttellB.NottotellC.NottellingD.Notelling()11.________inbed.It’sbadforyoureyes.A.NottoreadB.Don’treadC.Don’ttoreadD.Notread(12.________Yourchild.We’lllookafterhim.A.NottoworryaboutB.Don’tworryaboutC.NotworryforD.Don’tworrywith4()13.Theyareverytired.Why________havearest?A.nottheyB.donottheyC.don’ttheyD.notto()14.--Youlookrathertired.________stoppingtohavearest?--Allright.A.WhynotB.HowaboutC.WhynottoD.whydon’t()15.______tellalie.AHardlyB.NotC.NoD.Never、()16.Please________lookoutside.Lookattheblackboard.A.notB.don’tC.aren’tD.can’t()17.Herdoctorsaid:“________worksohard”A.StopB.Don’tC.Can’tD.No()18.1.TheTVistooloud.Please________.A.turnitdownB.toturnitdownC.turndownitD.toturndownit()19.________whenyoucrosstheroad.A.DocareB.CareC.BecarefulD.Tobecareful()20.________himthesecret,willyou?A.Don’ttellB.NottotellC.NottellingD.Notelling()21.Ifyouwanttostay,letmeknow,______?A.willyouB.shallweC.doyouD.dowe()22.Nevercomelateagain,______?A.willyouB.won’tC.doyouD.doeshe()23.John,readthetextforus,________?AdoesheBwillheCdoyouDwillyou()24.Let’sdoitatonce,________?AshallweBwillyouCdoweDdoyou()25.Letusdoitatonce,________?AshallweBwillyouCdoweDdoyou三．用括号内所给动词的适当形式填空。1.It’sanimportantmeeting.__________(not,be)late.2.____________(not,make)anynoise!Yourmotherissleeping.3.____________(not,speak)withyourmouthfulloffoodand____________(be)polite.4.____________(not,talk)and__________(read)aloud.5.____________(not,leave)yourhomeworkfortomorrow,Larry.6.____________(notlook)out!Acariscoming.7.____________(give)ustenyearsandjustseewhatourcountrywillbelike.8.____________(not,let)thebabycry.9.Wearmoreclothesoryou___________(catch)acold.10.Let’s____________(not,say)anythingaboutit.11.No.（park）四．句型转换1.Willyoupleasereaditagainmoreslowly?（改为祈使句）__________againmoreslowly,please.2.Ifyoudon'tlistentome,I'llgo.（改为同义句）__________me,orI’llgo.53.Let'swatchthesportsgames.（改为反意疑问句）Let'swatchthesportsgames,__________?4.Theteachersoftentellthestudentsnottobecareless.（改为祈使句）__________careless,please.5.Ifyoumove,you'lldie.（改为同义句）__________,oryou'lldie.
