展开Reading and Thinking: A Pineer fr All Peple教案
文本简析
本单元阅读文本话题是袁隆平和他的创新性农业研究成果。通过介绍袁隆平的成就与梦想,特别是他从事农业研究的初衷,引导学生认识农业创新对缓解世界饥饿问题的重要意义,与此同时,启发学生树立崇高的理想,执着地追求梦想。
本文是一篇人物介绍。全文六个段落呈现了人物介绍类文本常见的内容结构:身份简介(第一段)——核心事件(第二、三段)——影响力(第四段)——人物评价(第五、六段)。本文以标题“A Pineer fr All Peple”为统领,以袁隆平研发杂交水稻这个事件为核心,描述了他从事农业研究的初衷、为消除饥饿问题所做的努力、贡献及影响,赞扬了这位“全人类的先驱”的悲悯之心、使命感、创新能力、淳朴品质和追梦精神。
设计教学活动时,应帮助学生整理人物介绍和杂交水稻的话题类语言。值得关注的是,文本多处运用了对比的写作手法来突显袁隆平的品格和特质。在强调杂交水稻的影响力时,则主要运用了列数据的手法。让学生分析文本的写作手法,能提高学生运用写作技巧表达意图的意识和能力。此外,可引导学生关注第五段首句在内容上的承上启下作用,以及第六段首句作为段落主题句的作用。让学生对句子的作用进行分析,能增强学生对段落架构技巧的感知。
