一、教学设计与说明
1. 教学目标
本课为本单元的第 5课时,核心目标为引导学生识别并理解说明文的文体特征和结构,
发掘文中提及的三处地方的神秘之处,并且分享对此神秘事物的感受和探索未知世界的求
索精神,对本单元“奥秘探索”主题语境下的内容进行回顾,尝试提出假设并给出合理的
解释。
2. 设计思路
本课为本单元的第 5课时,教学内容为 Reading B语篇。导入部分以学生比较熟知的
世界最高点引出世界最低点,并导入本课时内容。接着引导学生根据标题预测语篇内容。
然后学生通过略读对语篇文体进行判断,并且利用语篇结构概括文章大意。学生扫读文章
后,填写关于文中三处神秘地的表格,包括地点、居住者和探索过程中的困难等。对语篇
基本理解之后,学生对三处地方进行比较,进一步思考最易和最难到达的地方并且阐述原
因,同时思考作者写作此文的意图。在此基础上,学生以小组为单位发表看到如此景色时
的感受,选择最想去探索的一处地方并且讲述理由。此后,学生小组合作绘制海报并且进
行展示,将文章内容再次以视觉化的形式呈现出来,鼓励学生进行创造性的表达。
最后,教师邀请学生对本单元中所涉及的神秘之处进行回顾,并且引导学生以假设和
解释的模式对其进行梳理。回家作业中涵盖对本项任务的润色或者重新寻找一处神秘之处
并提出假设和给出解释。此外,回家作业还将包含对课堂海报展示的文字性写作以帮助学
生在语法和词汇层面有进一步的优化。
3. 重点难点
理解本说明文的特征和结构;了解文章中的三处神秘地点;表达分享见此景的感受和
