Unit 6 When was it invented?（说课稿）高霖一、教材分析1、教学内容: 本节教学内容为人教版英语Book 9 Unit 6，话题为讨论介绍物品的发明历史和用途，主要是让学生能够正确熟练地听懂并运用被动语态来介绍物品的发明过程和历史，通过本节课的学习，学生需要熟练掌握一般过去时态的被动语态，在学习中，懂得人类的科学发明创造了丰富的物质文明，激发创造发明的能力和愿望。 2、教材的地位和作用: 本节课内容中的被动语态，是中考的一个重点，也是难点，根据英语课程标准要求“能够灵活运用英语去做事情”，学生必须通过学习能够正确地运用本单元所学的被动语态，去描述物品的被创造、被发明的历史过程，从而达到学以致用的目的。二、说教学目标: 依据初中英语新课标的要求，我为本课确定了三项教学目标： 知识：1、熟练掌握与发明相关的事物名称（heel, scoop, zipper) 2、熟练掌握一般过去时态的被动语（was/were+p.p.）能力：1、能听懂含有一般过去时态被动语态的简短对话。 2、能运用一般过去时态被动语态谈论历史上的发明。情感：在学习中，懂得人类的科学发明创造了丰富的物质文明，激发创造发明的能力和愿望。并乐于参加学习小组活动，积极合作。三、说教学重难点 根据教学大纲要求，教材编排特点，并从学生的实际出发，我将本课的重点与难点确定为： 学习重点： When was the invented? Who was it invented by? What are they used for? 学习难点：熟练掌握一般过去时态的被动语态四、说教法和学法: 1、教法分析: 基于新课标要求要发挥学生的主体性，鼓励学生用自主、合作和探究的方式进行学习的理念，我将采用以下教学方法： （1）旧知复习：采用复习一般现在时的被动语态的知识，去复习被动语态的基本结构，为接下来的学习打下基础。 （2）对比引导：通过读句子组，寻找差异，并总结出一般过去时的被动语态的基本结构和句型转换，激励学生参与学习、自主学习，可以更好地理解和加深学习印象。 （3）听力训练：鉴于学生在听力方面基础较差，所以加强了听力训练，采用各种形式的听力方式去锻炼提高听力能力。 2、学法分析: （1）自主归纳法：为了鼓励学生参与学习，采用对比分析，再总结的方法去鼓励学生对比学习基本结构，加深学习印象。 （2）多样听力训练法：在听力练习中，采用听录音连线、听录音填空、听录音排序等形式，进行专项听力训练，以提高听力能力。 （3）例子激励法：为了激发学生对发明物的了解和学习，也为了给写作做好铺垫，选用几个很有趣的发明项目去激励学生学习和探究，拓展知识面。五、说教学过程 经过以上对教情，学情的分析，我将本课的教学过程设计为以下几个环节：（一）Review （复习检测）用所给词的适当形式填空 （设计意图：通过课前检测，既检测了一般现在是的被动语态的学习效果，又很好地为接下来的新知识的复习奠定基础。） （二）Self-study（自学） Task 1: The Passive Voice in the past tense(一般过去时态的被动语态）【自主学习，比一比，变一变】【自主总结规律，小组内交流】（设计意图：对比练习，寻找规律总结出一般现在时与一般过去时态下的被动语态的基本结构的区别化解学习难度。）被动语态 (Passive Voice)基本结构： 一般现在时态的被动语态，基本结构：am/is/are +P.P. _时态的被动语态，基本结构：_被动语态的几种句型： 肯定句：A sweet song was sung by her on the stage. 否定句：_ 一般疑问句：_（设计意图：总结并展示规律，从句型变化中去学会灵活运用知识的能力，感受各种句型下的变化。） Task 2: Listening practice（听录音，完成任务） 1a & 1b 1.
