课型:读写课

语篇类型
该文本是一篇关于环境问题的报告,介绍了漓江水污染的形成原因和治理措施,并探讨了环境问题是需要全球共同面对和携手解决的问题,有意识地培养人类命运共同体意识,节约地球资源,保护地球家园这一主题意义。
语篇分析
报告是一种常见的应用文体,报告正文通常包括问题描述、问题产生的原因分析、解决问题的具体措施以及成效。本节课的文本正是一篇关于漓江水污染治理的报告,全文皆为事实性信息,其目的是为了客观地汇报漓江水污染治理的措施和成效。全文分别四个段落,结构清晰。第一段引出文本话题,介绍了漓江繁荣的旅游业给漓江水质带来的负面影响。第二段分析问题产生的原因,例如:游客往漓江扔垃圾、游船上的厨房使用过的食用油被倒入漓江等。文中多处使用了体现这些成因严重性的词汇,(如:suffered greatly, increasing volume of tourists, frequently threw garbage, rapidly) 第三、四段呈现解决问题的具体措施和计划,包括优化家庭废弃物的手机和运输方式、关闭或搬迁污染企业、媒体宣传环保意识等。国家还制定“水十条”、“河长制”等有力政策,推动全国河道治理。作者在分析原因和呈现解决措施时,使用了大量的过去进行时和被动语态,(如:were using, was often thrown into, were used to increase, was damaging, steps should be taken, was improved, were closed or moved, were introduced)增加了文章的主观性和说服力,营造了身临其境的画面感,突出漓江水污染问题的严重性和国家治理措施所施取得的伟大成效,引起读者共鸣。
学情分析
本节课授课对象为高二理科实验班。学生已经具备比较成熟的阅读能力和掌握跳读、略读等阅读技巧,大部分同学都具有一定的英语写作能力和语言储备,为了重点让学生在堂上进行输出,巩固输入部分提炼的结构化知识和语言表达,课前学生通过学案对课文进行了预习,并两人一组通过制作思维导图,充分预习了文本第二、三段中重点内容。在本课学习之前,学生对环保类文本的介绍还没有系统的归纳和梳理,学生对漓江水污染治理问题不太熟悉,对如何撰写“环境问题报告”也了解不多。因此,本节课重在指导学生掌握报告文本的写作方法。
教学目标
在本课学习结束时,学生能够:
阅读漓江水污染的成因和治理措施,理解环境问题是需要全球共同面对和携手解决的问题,培养文化意识。
观察文本的标题、词汇云图和文本内容等语篇特征,了解报告文本的语篇结构和写作方法,初步建立文本意识。
通过跳读和略读,获取环境问题报告语篇的结构和语言特征,并迁移到笔头和口头输出中,学会撰写环境问题报告以及口头分享,培养语言表达能力。
利用评价标准评价自己与他人的作品,培养批判性思维能力,指向学科素养发展。
结合东莞打造“湾区都市,品质东莞”推出的《东莞市生活垃圾分类三年行动方案(2020-2022)》,指导学生撰写一篇关于“垃圾分类”的报告,把所学的知识进行迁移与创新。

七、教学反思
本节课以“保护环境”为主题语境,基于对文本和学情的分析,执教老师确定了本课的教学目标,并设计了五个层次的教学活动。教师先借用旅游短片、实景图片及头脑风暴环节,创设情境,引入本节课主题,激活学生已知,调动学生学习积极性。随后,教师引导学生关注文本体裁,梳理结构。利用思维导图可视化工具帮助学生获取事实性信息,通过小组讨论内化信息。接着,教师指导学生深度理解文本,通过“写作圈”活动,完成模仿写作。最后,提供真实情境,展示小组成果,并对学生作品进行评价,发展学生的批判性思维,鼓励创意表达。最后的作业设计既包括巩固所学内容的任务,也包括了扩展性任务,分层可选择的作业有效地兼顾了学生的个体差异。
