变；,练习题（略）,Thankyouforyourcoming！,Goodbye!,学习目标1、能邀请朋友、提出活动的建议、与陌生人闲聊等；2、在不同的场合，得体地运用语言。如何得体地接受和拒绝邀请、请求许可、求帮助、有礼貌地对不良行为提建议等；3、写作策略:如何写书信。,InterpersonalRelationships,。,人际关系,ComplaintsB.Make,acceptinvitationsC.Make,declineinvitationsD.MakerequestsoraskforhelpE.AskforpermissionF.Smalltalk聊天G.Makesuggestionsforfreetimeactivities空闲时间活动建议。,CouldyoupleaseputthemintoChinese?,拒绝邀请,()1.-Letsplaysoccer!-Thatsoundsgreat!()2.-CouldIplaycomputergamesforwhile?-Sure.Buthomeworkfirst.()3.-Canyoucomeandwatchmovieswithus?-Sorry,Ihavetovisitmygrandparents.()4.-Canyoucometomyparty?-Sure,Idloveto.()5.-Itsaniceday,isntit?-Yes.Ihopeitcanlastlong.()6.-Wouldyoumindnotsmokinghere?-Sorry,Iwont.()7.-Couldyoupleasehelpmedosomechores?-OK.Imcoming,Mom.,-Letsplaybasketball!-_.,Soundsinteresting,-Wouldyoumindopeningthewindow?-_.,No,notatall./Certainlynot./Ofcoursenot.,-Thebusoftencomeslate,_?-Yes.Ihopeitwillbeontimetoday.,doesntit,-_Ihavealookatyourpictures?-Hereyouare!,Could,-_youpleasetellme_Ishouldbuy.-Takeiteasy.Dontbenervous.,Could,what,WritePforPermissionandRforRequest.,(许可),（要求）,()1.Mom,couldIwatchTV?()2.Dave,couldyoufoldyourquilt?()3.CanIuseyourcarplease,Dad?()4.Couldyouhelpmecarrythebox,Jane?()5.CouldIuseyourcomputernow?()6.Couldyoupleasecleanthelivingroom,Alice?,P,P,P,R,R,R,Itsa_!Towhom_Time:_Place:_Fromwhom_Comeandhavefun!,BirthdayParty,Jim,6pm,Fridayevening,220#GardenRoad,Tom,Aninvitation,-_youcometomyparty?-_._,Sure,Idloveto.,Sorry,Ihaveto/amdoing,Can,Makeaninvitation,Jimscalendar,He_(study)foratest.2.He_(go)camping.3.He_(see)adentist.4.He_(have)apianolesson.5.He_(babysit)hissister.6.He_(go)tothemovieswithfriends.,用“haveto”和“bedoing”完成Jim周一到周六的日程表,Hi,Tom,Thanksfor_me.Id_tobutIcant.Iamverybusythisweek._Fridayevening,I_.Butthisweekend,I_,_youcometothemovieswithus?Jim,inviting/asking,love/like,On,havetobabysitmysister,amgoingtothemovies,Can,Declineaninvitation,Anna,Acceptaninvitation,doesntknowtheway.,Askingforhelp_!,politely,Couldyoupleasetellme_?,220#GardenRoad,howtogettoGardenRoad,howIcangettoGardenRoadwhereGardenRoadisifthereisGardenRoadnearherethewaytoGardenRoadwhichisthewayto,Annahassometroubleintheparty!ShedoesntknowanyoneexceptJim.,SmallTalk,Itsanexcitingparty,isntit?Themusicissonice,isntit?Hesingswell,doesnthe?,Smalltalk,1.Thepartyisreallygreat,_?2.Thefoodisdelicious,_?3.Shesingsreallywell,_?4.YouareTomssister,_?,isntit,isntit,doesntshe,arentyou,Politecomplaints,1.Wouldyouminddoing?,3.Couldyoupleasedo?,2.Wouldyoumindnotdoing?,4.Couldyoupleasenotdo?,Wouldyouminddoing?,Wouldyoumindnotdoing?,Sorry,Iwontdoitagain.,No,notatall.,Notatall.,Imsorry.Illdoitrightaway.,OK.Illdoitinaminute.,Notatall.,No,notatall.,中考临近，学生的压力越来越大，老师的作业多、课外活动减少等等，这让学生感到很烦恼。请你(PingPing)写一封100词左右的信给你的杨老师，表达你对现状的看法，并提出你的请求。,Letswrite!,Readcarefullyandmakesurewhatwehavetowrite!
