Unit 7 What's the highest mountain in the world？SectionB1a-1d课时教学设计
课型 听说课 课时 1
教材分析
本课是一节听说课，话题过渡到了动物，呈现了大象和熊猫的相关内容。1a-1e部分一方面巩固含有数字的事实描述，另一方面也拓展学习更多表示比较的句式，如多倍数的表达等。1a通过呈现大象和熊猫的信息，引导学生用比较句型将两种动物进行比较，为后面的听力做铺垫。1b-1c的听力内容主要是围绕熊猫宝宝的描述，进一步学习度量的表达。1d是听力活动的延续，让学生将听到的信息用对话的形式进行输出。
学情分析
八年级学生对色彩强烈的图片比较有兴趣，使用多媒体课件能调动学生的积极性，让学生比较直观和轻松的学习。同事学生不喜欢单独回答问题，喜欢集体回答，所以学习过程中多采用两人合作和小组合作探究，以及集体朗读回答等方式，通过反复积极的操练，使他们更快掌握目标语言，也可以增强合作意识。
课时教学目标
语言能力：能够在认识动物的情境中正确使用新词汇和形容词的比较级描述动物信息，比较两种动物，以听说等方式理解和谈论动物事实； 学习能力：能够通过谈论有关动物及动物宝宝的各类信息，学会用倍数表达来谈论两个事物;巩固用含有数字的事实描述事物，拓展学习更多表示比较的句式。 思维品质： 能够在听说活动中准确获取并清晰表达有关两种动物的比较以及动物宝宝的信息，提高思维的逻辑性、深刻性和批判性。 文化意识：通过对比学习幼年和成年大熊猫，增强动物保护意识，激发学生敬爱生命的思想。
教学重难点
教学重点：掌握本课时词汇；学会用倍数表达来谈论两个事物； 教学难点：巩固用含有数字的事实描述事物，拓展学习更多表示比较的句式。
