一、教学目标
语言能力:运用本单元核心词汇(如 ocean, tiny, protect 等)和形容词 / 副词最高级(如 the largest, the most beautiful),完成动植物海报的标题设计、信息收集(名称、栖息地 / 生长地、选择理由、有趣事实)及班级展示,提升英语表达准确性。
学习能力:通过小组协作(资料收集、海报制作、展示分工),培养主动交流、任务分配的能力,感受合作学习的乐趣。
文化意识与情感态度:梳理动植物介绍的核心维度,理解动植物与人类的依存关系,深化 “爱护动植物” 的环保意识。
二、教学重难点
重点:1. 掌握动植物介绍的核心要素(名称、栖息地 / 生长地、选择理由、有趣事实);2. 正确运用形容词 / 副词最高级描述动植物特征(如 The blue whale is the largest animal on earth)。
难点:1. 小组协作中高效完成任务分工,确保信息完整;2. 用简洁、通顺的英语描述动植物的 “有趣事实”。
三、教学准备
多媒体设备(展示课件、示例海报、词汇复习材料);
小组活动材料:卡纸、彩笔、记号笔(用于制作海报);
词汇卡片(复习 ocean, except, live up to 等核心词汇);
信息收集参考资料(如向日葵、银杏、蝴蝶等动植物的基础信息)。
四、教学过程
(一)复习导入:激活旧知(5 分钟)
词汇与句子回顾:通过课件呈现填空题,学生口头作答,巩固本单元核心词汇和句型:
名词:海洋(ocean)、极小的(tiny);
短语:和…… 一样重(as much as)、活到(live up to);
句子:蓝鲸是地球上最大和最沉的动物(The blue whale is the largest and heaviest animal on earth)。
过渡:引出本节课任务 —— 通过 “制作动植物海报”,运用所学知识介绍神奇的动植物。
(二)小组活动:海报设计与制作(30 分钟)
1. 步骤 1:确定海报标题(4a)(7 分钟)
课件展示标题示例:The Cutest Animal, The Most Amazing Plant, The Oldest Tree 等;
小组讨论:选择现有标题或自主创作(如 The Most Interesting Insect),确定本组海报主题(植物 / 动物);
教师巡视:指导学生标题需贴合 “amazing” 主题,避免偏离。
2. 步骤 2:收集核心信息(4b)(10 分钟)
明确信息维度:①名称;②栖息地 / 生长地;③选择理由;④有趣事实;
小组协作:参考课件示例(如向日葵:生长在温带 / 热带阳光充足的田野,花盘随太阳转动),分工查资料、记录信息;
教师支持:对信息模糊的小组(如 “银杏的栖息地”)提供提示(如 in Shandong)。
3. 步骤 3:制作海报(4c)(8 分钟)
分工创作:小组内一人画插图(如向日葵、蝴蝶),两人写文字(标注信息维度),一人检查语言(如最高级使用是否正确);
要求:文字简洁、插图贴合主题,突出 “amazing” 特征(如 “蓝鲸重达数百公斤”)。
4. 步骤 4:展示与投票(4d)(5 分钟)
小组展示:每组派 1 名代表,用课件模板介绍:“Let me tell you about... Its name is... It grows in... I chose it because... Some interesting facts:...”;
全班投票:根据 “内容完整、表达通顺、创意性”,评选 “最佳海报小组”,颁发口头表扬。
(三)课堂小结:梳理方法(5 分钟)
回顾动植物介绍框架:
植物:特征(one of the most beautiful)、生长地、象征意义(如向日葵象征乐观)、用途(如葵花籽可榨油);
动物:特征(the heaviest)、栖息地、寿命(live up to... years)、生态角色(play an important role);
强化最高级用法:强调 “三者及以上比较” 时用 “the + 最高级”(如 The blue whale is the largest animal on earth)。
(四)作业布置(5 分钟)
写一篇 80 词左右的短文,介绍自己最喜欢的动植物,要求:
包含 4 个核心信息(名称、栖息地 / 生长地、选择理由、有趣事实);

五、板书设计
板块 内容
