Unit 1 课时3 Section A Grammar Focus（情境教学课件）英语新教材人教版九年级上册

LearningObjectives通过本节课的学习，学生能够：1.能通过观察，识别并归纳核心语法结构：usedto+动词原形（过去习惯/状态）和现在完成时（have/has+过去分词）的用法及标志词（yet,ever,just,for,since）。能区分usedtodo、一般过去时与现在完成时的不同语境与含义，理解它们在描述“变化”主题中的功能差异。（学习理解）。2.能独立完成4b对话填空，4c短文填空，综合运用usedto和现在完成时，描述过去与现在的对比变化。（应用实践）3.能创造性地运用本课语法，对“交通发展与生活改善”形成辩证的价值理解，并用英语表达对家乡发展的自豪感。（迁移创新）。01Lead-inDiscussLookatthesesentences,telltheverbtenses.Hevisitedhisgrandparentslastweek.Iusedtogetupat6:30,butnowIgetupat7:00.Ihavefinishedmyhomeworkalready.UsedtoPresentPerfectSimplePastDiscussLookatthesesentences,telltheverbtenses.Tomusedtoliveinasmallvillage.TomworkedinShanghailastyear.Tomhaslivedinthreedifferentcities.Todaywewillfocusonexactlythesethreewaysoftalkingaboutthepastandpresent.UsedtoPresentPerfectSimplePast02PresentationHebecameagoodfriendofyourgrandfatherabout20yearsago.Theyhaven’tseeneachotherforages!Weusedtohavetotravelfartoseeadoctor.Ourvillagehasjustbuiltanewhospital.Manypeopleusedtoworkinbigcities.Now,moreofthemhavecomebacktoliveandworkhere.Circletheverbs.Workinpairs,Whichsentencestalkaboutapastaction?Whichtalkaboutapasthabit?Whichtalkaboutaresultnow?GrammarFocusSimplePastUsedtoPresentPerfect此处
