英语人教版四年级下册unit4第三课时.doc

Unit4第三课时一、教学内容分析：本节课是PEP教材四年级下册At the farm中的第五课时，本单元的话题是At the farm，通过前几课时的学习学生已经对农场有了一定的了解，并学习了和蔬菜有关的单词和句型，本课时呈现的是农场的另一场景图， 图中引出了本课要求重点掌握的单词sheep，hens，cows，horses以及句子These are sheep. Wow! Theyre so cute.通过本节课的学习让学生们知道农场不仅可以种植蔬菜，还可以饲养动物。二、学情分析：学生在三年级已经学习过部分常见动物的名称，他们对小动物很感兴趣，因此本课时要学的动物单词能激发学生的兴趣，并且通过前几课时的学习，学生对农场并不陌生。但是四年级的学生注意力不够集中，所以在本节课中我设计多种有趣的活动来吸引学生的注意力，让学生参与到课堂中来，充分发挥学生们的主观能动性，培养学生们综合运用语言的能力。另外，部分学生基础知识较差，对自己缺乏信心，因此课堂中老师应当给予及时的鼓励。三、教学目标1.语言技能目标：（1）能够运用句型These are. Theyre so.描述农场中的动物，并对农场的牲畜进行简单的交流。（2）能够辨认农场中常见的牲畜。2.语言知识目标：（1）能够听、说、认读本课时的主要单词：sheep，cow，hen，horse及它们的复数形式sheep，cows，hens，horses。（2）能够听、说、认读句子“ These are.

Theyre so.2.难点：horse，sheep的复数形式表达及其读音。四、教学过程ProceduresTeachersActivitiesLearnersActivitiesPurposesStep IWarm-up/revision1. Greetings.T:Goodmorning,boysandgirls.T:Nicetomeetyou.2.

Theyre so long.Ss: No, they arent. They are potatoes.日常的问候可以拉近师生间的距离以及集中学生的注意力。通过让学生唱关于农场的英文歌，既把学生的注意力集中到课堂中来，活跃了课堂气氛，同时将今天上课的主题At the farm自然的引出。通过分组激发学生的竞争意识。把课堂交给学生们，通过有趣的猜蔬菜游戏，让学生参与到英语课堂中，通过这种方式既复习已学过的单词和句型，以旧带新，引出后面新单词的学习，又调动了学生们的积极性。Step II PresentationT: There are also many animals on the farm.

Listen to the tape and read after it.告诉学生农场里除了蔬菜还有动物，引出本课要学习的动物单词。顺应刚才猜一猜的游戏方式自然引出sheep一词。通过可爱的绵羊图片引出cute一词。horse的复数horses的读音有点难度，教师要多次示范正音。通过鸡蛋延伸到母鸡，并通过简笔画的形式画出母鸡。注意让学生们模仿磁带中的语音语调，锻炼学生们的听力及口语。Step Practice1.Draw and sayOne student draws, the other says the English names.2.Game2: Whichoneismissing?T shows the picture of the some animals and let Ss say which one is missing.
