一、教材分析 Analysis of teaching material
What:1. 3a 部分：呈现含比较级的句子，让学生识别并在教材Section A找更多例子，如 “It is more colourful than last year.”“Emma is taller than Ella” 等，体会比较级用于两者比较的用法 。2. 3b 部分：通过用括号内单词编写一般疑问句及回答，练习 “比较级 + than” 和 “as + 原级 + as” 结构。如用 “you / serious / cousin” 等词汇，构造 “Are you more serious than your cousin ” 并回答 “I am less serious than he is.” 这类句子，强化对两种结构的运用 。3. 3c 部分：借助广州和芝加哥的城市数据图表，用 “as...as”“比较级 + than” 结构对比两城市的人口、面积、气候等，如根据人口、面积等数据，完成 “The population of Chicago was smaller than that of Guangzhou in 2022.” 等句子，将语法知识用于实际信息对比场景 。Why:1. 语言知识体系需求：比较级和 “as...as” 结构是英语语法基础且常用，用于描述事物间的异同、程度比较，是学生掌握英语表达差异、进行准确描述的必备知识，能丰富语言表达，让学生从简单描述进阶到对比描述 。2. 实际交流应用：在生活中，人们常比较事物特征（如城市间人口、气候，人物间身高、能力等），这些语法能让学生准确交流此类内容，提升语言运用的实用性，比如旅游时对比不同城市，日常讨论朋友间特点 。
How:1. 3a 环节：教师可先领读句子，讲解比较级（如多音节形容词前加 more 构成比较级，部分单音节词变 -er ，如 tall - taller ）和 “than” 表对比的用法；再让学生自主在Section A找例子，分享并分析，加深对结构的感知 。2. 3b 环节：教师先示范第一题，讲解构造一般疑问句（Be 动词 / 助动词提前，结合比较级 / as...as 结构）和回答的逻辑；然后让学生分组或个人完成，过程中巡视指导，纠正语法错误，之后选取典型答案展示、点评，强化结构运用 。3. 3c 环节：先引导学生观察图表，理解各项数据含义；接着讲解方框词汇（large, small 等）在比较中的用法；再让学生尝试完成句子，教师可先做第一题示范（如根据人口数据，Chicago 人口比 Guangzhou 少，用 “smaller than” ）；之后让学生独立或合作完成，最后核对答案，讲解易错点，比如温度比较中 “warm”“cool” 的正确使用，巩固用数据对比、运用语法的能力 。
二、教学内容 Teaching content
知识感知：借3a中含比较级的句子（如“It is more colourful than last year.”等 ），让学生识别比较级形式，并从Section A找更多实例，初步感知“比较级 + than”用于两者对比的语法结构 。 结构练习：3b通过编写一般疑问句与回答，让学生运用“比较级 + than”（如“Are you more serious than your cousin ” ）和“as + 原级 + as”（如“She is as slim as me.” ）结构，强化对这两种语法结构的运用，掌握其在问答语境的表达 。 实际运用：3c依托广州和芝加哥的城市数据图表，引导学生用给定词汇（large、small等 ），结合“比较级 + than”和“as + 原级 + as”，对比两城市人口、面积、气候等，将语法知识迁移到真实信息对比场景，提升语言运用的实用性 。4. 能力进阶：整体环节从识别语法（3a），到基础造句练习（3b），再到结合实际数据的综合运用（3c），由浅入深，帮助学生逐步掌握形容词、副词比较级与原级在不同语境的正确表达，提升英语语法运用和实际交流能力 。
