Unit 8 Our Blue Planet
Theme Reading教案
一、教学内容分析
本课时为主题阅读活动，帮助学生运用本单元所学的思维技能和阅读策略开展主题阅读。通过阅读沙漠家庭的真实案例，学生将学习如何在缺水环境中合理用水，并通过可视化策略深化理解。活动包括小组讨论节水方法、阅读理解正误判断、图表分析及词汇应用，旨在培养学生的节水意识与批判性思维。
二、语篇分析
【What】 本课时语篇例举了一个生活在沙漠中的家庭的用水情况。这家水源不足，很少种花种草，一周只能快速洗一次澡，洗澡时要收集水，洗完还会重复利用。沙漠降雨少，多数人从地下取水，需花很多钱挖井。作者感慨自己幸运，无需担忧用水，开始节约用水，并呼吁大家一起行动。 【Why】 本课时通过梳理语篇的主旨大意及关键信息，帮助学生在语境中复习和巩固已经习得的词汇、表达方式，思维技能和阅读策略。语篇传达了水资源在部分地区极度匮乏的现实，帮助学生认识到水资源的珍贵性。同时，作者呼吁学生加入节约用水的行列，共同为改变现状做出贡献，引导学生养成节约用水的良好习惯，珍惜并合理利用水资源。 【How】 本阅读语篇为信息类文本，介绍了沙漠中人们的用水情况，同时表达了作者的节水呼吁，旨在向学生传递关于沙漠水资源和节水的相关信息。全文共三个段落：第一段主要表明沙漠中有人类居住，第二段具体举例，一个居住在沙漠的家庭的日常用水情况，最后一段表明自己的感受，并发出呼吁，升华主题。语篇用词较为简单直白，多为基础词汇，如“desert”“water”“family”“important”“seldom”“collect”等，便于读者理解。部分词汇体现情感态度，如 “valuable”“lucky”。句式以简单句为主，结构简洁明了。如“They seldom plant flowers or grass.”“It doesn’t rain much in the desert.”等，表述直接，易于读者把握信息。
三、学情分析
通过前面几课时的学习，学生已经积累了一些与“沙漠”和“水资源”主题相关的语言素材，具备了一定的语言基础。文章内容贴近生活常识，关于沙漠和水资源的话题能引起学生兴趣，学生凭借已有的生活经验和知识储备，能够理解文章大意，明白沙漠中人们用水困难的情况。因此，他们能够运用已学的阅读策略、思维技能来完成本节课的任务。但对于文中一些隐含的逻辑关系，如沙漠少雨与人们挖井取水之间的因果关系，以及作者由沙漠家庭用水状况引发自身节水意识的情感转变，初一学生分析起来可能存在一定困难，需要教师引导梳理。
四、教学目标
通过本课时的学习，学生能够： 运用可视化阅读策略，构建沙漠中节水行动的视觉化场景，加深对语篇的理解； 梳理和概括语篇的关键信息和主旨大意，绘制主旨与细节图； 通过谈论沙漠中的节水措施，感悟珍惜水资源的重要性，培养节约用水意识。
五、教学重难点
【重点】 运用可视化阅读策略，构建沙漠中节水行动的视觉化场景，加深对语篇的理解； 梳理和概括语篇的关键信息和主旨大意，绘制主旨与细节图。 【难点】 通过谈论沙漠中的节水措施，感悟珍惜水资源的重要性，培养节约用水意识。
