人教版八年级英语下册 Unit5 Section A 教学设计

一、单元主题分析本单元的核心话题围绕“意外事件与过去进行时”展开，旨在引导学生学习如何描述过去某个特定时间点正在发生的动作，以及当一个动作发生时另一个动作正在进行的情景。SectionA作为单元的开篇，承载着引入主题、呈现核心词汇与句型、初步构建语法概念的重要任务。通过对本部分的学习，学生将能够运用过去进行时谈论过去发生的事情，理解并运用“when”和“while”引导的时间状语从句，并为后续的阅读和写作积累必要的语言素材和表达能力。二、课时安排建议根据SectionA的内容容量与教学目标，建议安排2-3课时。本设计将重点阐述第一、二课时的详细教学流程，第三课时可根据学生掌握情况进行综合复习与拓展练习。三、第一课时教学设计(SectionA1a-2d)（一）课时主题Pastactionsinterruptedbyanotherevent(被另一事件打断的过去动作)（二）教学目标1.知识与技能：*学生能够理解并运用下列词汇：rainstorm,alarm,gooff,begin,heavily,suddenly,pickup,strange。*学生能够初步理解并运用过去进行时(PastContinuousTense)的基本结构：was/were+doing。*学生能够听懂并谈论过去某个时间点正在发生的事情，以及当某件事发生时另一件事正在进行的情景，初步感知"when"和"while"的用法。*能够完成教材1a,1b,2a,2b的听力与配对练习，并能根据1c和2c的提示进行简单的对话练习。2.过程与方法：*通过情境创设、图片展示、听力输入等方式引导学生感知新语言。*通过结对练习、小组讨论等合作学习方式，促进学生在互动中运用语言。*引导学生通过观察、比较和归纳，初步总结过去进行时的用法。3.情感态度与价值观：*培养学生在日常生活中观察和描述事件的能力。*引导学生关注天气变化及安全问题。（三）教学重难点1.教学重点：*过去进行时的构成和基本用法。*词汇：rainstorm,alarm,gooff,suddenly,pickup。*句型：Whatwereyoudoingwhen...?Iwasdoing...when...2.教学难点：*"when"引导的时间状语从句（主句用过去进行时，从句用一般过去时）的初步理解和运用。*正确运用"was"和"were"。（四）教学准备多媒体课件、录音机/播放器、教材配套听力材料、词汇卡片（可选）。（五）教学过程Step1:Warm-up(热身导入)(约5分钟)1.DailyGreeting&WeatherReport:*Greetstudentsasusual.*Ask:"What'stheweatherliketoday?"(引导学生回答)*Showsomepicturesofdifferentweatherconditions(sunny,rainy,cloudy,windy,stormy).Ask:"Doyoulikerainydays?Whatdoyouusuallydoonarainyday?"(学生自由回答，复习一般现在时)*Then,transition:"Sometimestheweathercanbeverybad,likearainstorm.Haveyoueverexperiencedarainstorm?"(引出话题和新词"rainstorm")Step2:Presentation(新知呈现)(约15分钟)1.Introducenewvocabulary:*Showapictureofarainstorm.Elicitorteach"rainstorm".*Showapictureofanalarmclockringing.Teach"alarmclock"and"gooff"(Thealarmwentoff.).Useactionsormimetohelpstudentsunderstand.*Showpicturesoruseactionsfor"begin","heavily"(e.g.,"Itrainedheavily."),"suddenly"(e.g.,"Suddenly,thelightswentout."),"pickup(thephone)".*Havestudentsrepeatthenewwordsandphrasesseveraltimesforpronunciationpractice.2.IntroducePastContinuousTense:*Setacontext:"Lastnight,therewasaheavyrainstorm.Whatwereyoudoingwhentherainstormcame?"(板书句型"Whatwereyoudoingwhen...?")*Model:"Whentherainstormcame,IwaswatchingTV."(板书"IwaswatchingTVwhentherainstormcame.")*Explainbriefly:Weuse"was/were+doing"totalkaboutanactionthatwasinprogressataspecifictimeinthepast.*Askafewstudents:"Whatwereyoudoingat8o'clocklastnight?"(引导学生用"Iwas...")3.Activity1a(Page33):*Directstudents'attentiontothepicturesin1a.Explainthetask:Matchthestatementswiththepictures.*Readthestatementsaloud.Studentsworkindividuallytomatch.*Checkanswersasaclass.Foreachpicture,ask:"Whatwasthegirl/boydoingwhentherainstormcame?"(引导学生尝试用过去进行时回答，教师给予提示和帮助)Step3:ListeningPractice(听力练习)(约15分钟)1.Activity1b(Page33):*Tellstudents:"Now,let'slistentoaconversationbetweenLindaandMary.Theyaretalkingaboutwhattheyweredoingwhentherainstormcame.Listenandnumberthepictures[1-3]intheorderyouhearthem."*Playtherecordingonce.Studentslistenandnumber.*Playtherecordingagainforstudentstocheck.Thencheckanswerstogether.2.Activity1c(Pairwork):*Askstudentstolookatthepicturesin1aagain.*Modeladialoguewithastudentusingtheexampleinthebox:*A:Whatwereyoudoingwhentherainstormcame?*B:Iwas...*Studentspracticeinpairs.Walkaroundtoprovideassistance.*Inviteafewpairstoactouttheirdialogues.3.Activity2a&2b(Page34):*Pre-listening:Introducethecontext:"Now,let'slistentoanotherconversation.It'saboutwhatpeopleweredoingatthetimeoftherainstorm."*2a:Tellstudents:"Listenandcirclethecorrectresponsesinthechart."Playtherecordingonce.Checkanswers.*2b:Tellstudents:"Listenagain.Fillintheblankswithwhateachpersonwasdoingatthetimeoftherainstorm."Playtherecordingagain.Studentsfillintheblanks.*Checkanswersbyasking:"Whatwasthegirldoingwhentherainstormcame?"etc.(板书几个关键句，如"Shewasdoingherhomework.")*Focusonthestructure:Underline"wasdoing"and"whentherainstormcame"inthesentencesontheboard.Pointoutthestructure:"I/He/She/Itwasdoing...when+subject+verb(pastsimple)."Step4:Practice(巩固练习)(约7分钟)1.Activity2c(Groupwork/Pairwork):*Explainthetask:"Workinpairs.Askandanswerquestionsaboutwhatthepeoplein2aweredoingwhentherainstormcame."*Usetheexampleinthebox:*A:Whatwasthegirldoingwhentherainstormcame?*B:Shewasdoingherhomework.*Studentspractice.Encouragethemtousetheinformationfrom2b.*Walkaroundtomonitorandhelp,especiallywiththeuseof"was/were".Step5:SummaryandHomework(总结与作业)(约3分钟)1.Summary:*Brieflyreviewthekeypoints:PastContinuousTense(was/were+V-ing),keywords(rainstorm,alarm,gooff),andthesentencepattern"Whatwereyoudoingwhen...?Iwasdoing...when..."*Ask:"WhendoweusethePastContinuousTense?"(引导学生总结：描述过去某个特定时间正在进行的动作)2.Homework:*Copythenewwordsandphrases(rainstorm,alarm,gooff,suddenly,pickup,begin,heavily)andmakesentenceswiththem.*Finishtheexercisesintheworkbookrelatedtothispart(ifany).*Thinkabout:Whatwereyourfamilymembersdoingat7o'clocklastnight?(为下节课做准备)（六）板书设计Unit5Whatwereyoudoingwhentherainstormcame?SectionA(1a-2c)NewWords:rainstorm,alarm(clock),gooff,begin,heavily,suddenly,pickup(thephone)SentencePatterns:Whatwereyoudoingwhentherainstormcame?Iwasdoing...whentherainstormcame.She/He/Itwasdoing...when...They/We/Youweredoing...when...Examples:I
