三年级上册英语教案Unit9On and off牛津译林一起.doc

教学内容：九年义务教育六年制小学教科书。牛津小学英语3a第一教时（a部分三、四两幅图；b部分相关单词）教学目标：1、能听懂、会说close/open及其应答语all right./ok等。2、能听懂、会说常见物品a door, a window, a box, a basket。3、能使用简单的祈使句表达“请别人干某事”的意思及进行应答。教学重点：1、单词：a door, a window, a box, a basket。2、日常交际用语：close/open及其应答语all right.教学难点：1、单词a basket 的读音2、能在情景中灵活运用本课所学的日常交际用语。教学建议：根据学生的认知规律，考虑到open和turn on、close和turnoff的意思相近，学生容易混淆，因此把一、二两幅图作为一教时，三、四两幅图作为另一教时。又因为open和 close比turn on和 turn off容易上口。所以第一教时先教open和close，第二教时再教turn on和 turn off的句型。课前准备：1、教具准备：磁带、录音机、实物：盒子、篮子、水果。盒子、篮子、门、窗的图片、2、板书准备：在黑板上预先写好课题unit 9 on and off教学过程：step1revision1、t: good morning,s1.s1:good morning, missjiang .t: how are you?s1: fine, thank you. and you?t: im fine, too.t:sit down ,please.（重音：please）2.t：whats your name?s2:nice to meet you.t:nice to meet you,too.（并伴随着握手的姿势）t：sit down,please. （重音：please）新授please: 反复操练几个对话，强调please,以此来讲授please的意思，让学生了解其意思。3.（在学生操练完各个复习的对话时）t：sit downs:please（together）step2 presentation1、door, open the doort: today, we will learn some new things,look,its a door,a door ,whats the meaning of door?ss:“门”t:door ,door ,门（领学生读数遍）t：there are so many people in the classroom,i feel hot ,so i want to open the door ,open ,open ,open the doort:伴随肢体语言讲解open the doort:open the doors:all right/ok2.close the doort:but ,today ,ive got a cold,i feel cold now,so i want to close the door.t:伴随肢体语言讲解close the door3.t:close the doors:all pare:open and closet:做关门的动作s：closet：做开门的动作s：open（do this many times ,let the students understand “open”and “close”）5.（多媒体课件呈现实物）同样的方法讲解basket,window,boxbasket a a:window iiboxocstep3consolidation and practicerevesion the new words:1.read the new words together2.use cai to show the part of the pictures,let the ss guess:whats this?3.put the cards of the new words on the right things.step4 presentation1.open the boxclose the box2.open the basketclose the basket3.open the windowclose the window（can let the ss follow the orders,and do many times ）4.drillreview :open the ，all rightclose the ，all right（t-s,s-t,t-t）step 5 consolidation1. read the new sentences on the blackboard together2. listen to the tape and read after it （p53）step 6 presentationt:what did david say at last?s:im sorry.t:why?s:因为大卫不小心把爸爸的衣服夹在门缝里头了，所以说“im sorry！”t:yes, when we do some wrong things ,we should say “im sorry！”step 7ending1. homework: listen to the tape and read after it （p53）2. read the new words many times.3. ending:oh,now ,its time to have a rest.lets stan
