第五课时一、课时内容B Lets talk B Lets play二、课时分析本课时是人教版四年级下册第四单元第五课时，与前几课时时紧密相连。围绕“参观农场”这一话题展开，主要通过对话学习句型What are those？They are.来询问物品的名称。 Are they? 及其答语No, they arent确认是不是某种物品。培养学生学习英语的兴趣，树立学好英语的信心。本课时是第一课教学内容的延续，重点是能够在情景中恰当运用“询问并回答物品名称”的句型。本课时包括Lets talk和 B Lets play两个板块。Lets talk版块通过呈现Mike与Sarah继续参观农场引出句型What are those？They are.Are they? 及其答语No, they arent对话的结尾生动有趣，很能引起学生的共鸣。 B Lets play版块用于操练B Lets talk板块的核心句型，要求参与表演的学生不能少于两人。本课时涉及的话题比较简单，重在对话的理解和运用。所以在设计本课教学时，我提供了不同的场景帮助学生理解对话和运用对话。做到操练与情境相结合，达到巩固语言和运用语言的目的。三、课时目标1. 能够理解对话大意。2. 能够用正确的语音、语调朗读对话。3. 能够在情景中恰当的运用句型：What are those? Theyre 问答物品名称。4. 能运用句型Are they ? Yes, they are./ No, they arent.确认是否为某种物品。5. 培养学生学习英语的兴趣，梳理学好英语的信心。四、课时重难点1. 重点 巩固单词：hen , horse , cow , sheep 能够听、说、认读句型：What are those? Theyre .Are they ? Yes, they are./ No, they arent.并能作出正确回答。2. 难点these 和 those 的发音及用法区别。五、教学准备：（1）多媒体课件（2）单词卡片：hen , horse , cow , cat , sheep, duck ,dog 等。（3）教学挂图（4）录音机及磁带（5）录制动物的叫声并制成课件六、教学过程Step 1 Warm up1.师生问候T: Good morning, boys and girls.Ss: Good morning, Mr/Ms.T: Nice to see you again.Ss: Nice to see you, too.T: Its time for English. Are you ready?Ss: Yes, we are ready.T: I have a song for you. Now lets sing together.2. 播放歌曲 Old Macdonald has a farm. 师生跟录音齐唱。设计意图：在愉快的氛围中，复习巩固了上节课的知识。Step 2 Lead in活动：猜图活动方案：老师把词卡翻过来放到讲台上，然后抽一张叫自告奋勇的学生到台前看看，其余的同学用Are these ? 来猜图片的内容。猜对了这位同学就要说：Yes, they are. 猜错了，则要说: No, they arent. 全班同学再接着问：What are these? 该同学就给出正确的答案。如：抽到卡片S全: Are these hens ?S1： Yes, they are.抽到卡片S全: Are these hens ?S1： No,they arent. S全：What are these?S1： These are sheep.设计意图：通过猜图游戏不仅复习了上节课学习过的动物名称单词，更为下一步的游戏和新知识的学习做了铺垫。Step 3 Presentation1.教学 Lets talk. 教学单词animals T：（老师课件展示一个农场边展示边介绍）This is a farm. 接下来手指农场问：How many animals do you see? 边说边板书 animals ，老师边领读边做各种动物所特有的动作，说明animals 是动物们的意思，开炮操练读 animalsSs:( 老师课件展示各种动物并引导学生一起回答）I see many animals.T: Yes, I see a lot of animals. （通过肢体语言引导学生明白a lot of 的意思） 随后老师边说边走到一位同学的面前看着他盒子里很多的铅笔说： Wow! You have a lot of pencils! 然后向同学们展示使学生明白a lot of 是许多的意思。设计意图：利用课件图片跟肢体语言教学单词， 更利于学生掌握和理解。 .教学 these 和 those 老师课件展示一群马在农场里的图片，然后手里拿着刚才游戏里抽出的绵羊的图片，边配合肢体语言边介绍说：T: （手举绵羊图片） What are these? Ss：（ 老师引导学生回答） They are sheep.T：（手指马的课件）What are those?Ss: They are horses.配合肢体语言重复朗读 these 和 those ，并板书these 和 those 解释两者的区别，适时提醒学生o-e 的发音，引导学生拼读单词those，再领读，学生击掌读。设计意图：利用教师提供的图片进行对话练习，通过肢体语言帮助学生理解词义及应用。 教学句型：What are those？ They are . What about those?T: (老师将事先准备好的“奶牛”和“鸭子”的图片贴在黑板的左边和右边，然后老师站到奶牛的旁边问：）What are these？Ss:They are cows.T：（然后手指鸭子问）What are those?Ss： They are ducks.指名学生说一说What are these？与What are those?的区别并告诉学生“What are those？”也可以用“What about those？来替换。设计意图：利用贴图片让学生重新感知 these 与those的区别及它们运用的语境。从而理解句型：What about those？的意思。 教师播放 Lets talk的录音，学生跟读，教师注意正音。 教师课件展示一个农场与学生根据农场图片示范对话。如：T: You have a lot of animals . What are those?Ss:(学生根据课件展示的动物回答）They are horses.T: How many horses do you have?Ss: I have seventeen horses.设计意图：提供场景，帮助学生理解和运用语言。2.教学 B Lets play活动：我来演你来猜活动方案：T: I can act like an animals . Look and guess. (教师表演一种农场动物的动作，如： horse . 提醒学生使用句子Is it a ? 进行猜测。教师再请一名学生一起表演一种动物，如 hen 。教师引导学生使用句子 Are they ? 进行猜测。设计意图：本活动用于巩固与拓展核心句型：Are they ? Yes, they are./ No, they arent.Step 4 Practice活动：听音猜动物活动方案：教师播放课件点击先发出动物的叫声然后问：What are those？学生用They are. 的句型来猜，猜对后，教师再次点击，出示该动物的图片。设计意图：本活动操练巩固了本课时的核心句型：What are those? Theyre Step 5 Summary T：Boys and girls, Lets look back this class. Which English phrases do you remember?Ss：Animals ; these ; thoseT：Excellent! Which new sentences do you learn today?Ss：-What are those? - Theyre .- Are they ? - Yes, they are./ No, they arent.设计意图：帮助学生整理和归纳知识点，加强学生的理解。七、课堂作业. 按要求写单词。1. this （对应词） 2. sheep （复数） 3. tomato （复数） 4.these （对应词） 5.
