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 thoseThey 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 thoseThey 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 up 1.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 animals Ss 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 thoseT 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 theseSsThey are cows.T（然后手指鸭子问）What are thoseSs 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 TBoys and girls, Lets look back this class.
