10、培养学生 综合语言运用能力。为体现“整体设计目标，体现灵活开放；开发课程 资源，拓展学用渠道”的基本理念，本课努力实施新课程所倡导的“任 务型教学” 。在设计本课时，我利用多种图片让学生感知环境的恶劣变化 发现现在的环境现状以及严重影响，一步步地调动学生的学习兴趣，并 使其乐于参与教学活动成为教学的主体。 本课设计的最大特色是以引导学生认识到环保的重要性为线索，逐 步拓展阅读后的语言生成能力，例如有 5 个不同的倡议形式呼吁大家参 与环保，以及最后环节每个同学参与环保行动并在白板上贴上自己的行 动便条，以达到情感文化品格的最后塑造，前后呼应，融为一体！ 二、教学背景二、教学背景 1. 教学内容
11、分析：本课是九年级第二单元话题的第三课时。通过阅读 1a,进一步学习各种污染对地球造成的危害和造成这些污染的原因， 培养 学生通过图片预测文章大意的能力，其中出现了很多关于环境的专业术 语，需要学生了解。1b 是训练学生运用不同的阅读策略完成不同任务和 给每段话选标题；1c 培养学生精读文章，合理地运用资源策略查找与环 境危害相关的信息，通过读写的结合训练，引导学生关注全球环境的现 状，意识到环境保护的重要性，树立正确的环保观念。 2. 学生情况分析：语篇是仁爱版英语上册的内容，这一阶段的学生，在 经历了两年的初中英语学习后，有了更丰富的词汇和语言表达能力，但 是对于阅读语篇理解后解决问题的方
12、式与能力有待进一步的加强与提 升。基于前两节课的学习学生对于本篇内容有所熟悉，这就降低了学生 的阅读难度， 同时学生可以用自己的方法去帮助对语篇进行分析与理解， 以及更好的解决文章后出现的问题，但学生需做好课前预习工作，才能 更好达成本课程设计的目标。 三、教学目标（以下各项可整合）三、教学目标（以下各项可整合） 1. 语言能力目标：1) Read and understand the text clearly. 2) The students are expected to practice their oral English and written English concerning
