思考、探究、讨论、小组交流、合作。三、情感态度与价值观明确青少年做家务的理由和自己能做的家务，能感恩父母，体贴家人，养成坚持做家务的好习惯。教学重点复习巩固本单元重点词汇和句型。教学难点培养写作能力。教法导航让学生动脑思考，动笔写，动手练。学法导航独立思考，小组合作。教学准备多媒体，练习。教学过程Step1GreetingsGreetthestudentsasusual.Step2RevisionAsksomestudentstoreporttheirhomework.Step3Discussion3a,Say：Doyouthinkchildrenshoulddosomechoresathome?Whyorwhynot?Discussthiswithapartnerandtakenotes.Thenasksomestudentstoreporttheirreasons.Step4Writing3b,Say：Nowit’swritingtime.PleasewritealettertotheSundayMailandexpressyouropinion.Youcanusethestructurein3b.Afterseveraltime，asksomestudentstoreporttheirletters.Step5SelfCheckSelfcheck1,Say：Therearemanychoreswecandoinourhouse.Pleasethinkoverandmakealistofchoresusingtheseverbs.Thenasksomestudentstoreporttheiranswers.Selfcheck2,Say：Asweallknow，wecanuse“could”toexpressrequestsandpermissions.Pleasedecidewhetherthesentencesarepoliterequestsorpermissions?Writethenumbersinthecorrectplacesinthechart.Thenasksomestudentstoreporttheiranswers.Selfcheck3,Say：Youdidverywell.Nowpleaseusethequestionsinactivity2towriteaconversation.Thenasksomestudentstoreporttheirconversations.Step6Exercises1.CouldIinvitemyfriends_____toourhouse?Yes，youcan.A.come
