Unit 3Section3 Writing课件-2025-2026学年沪教版（2024）八年级英语上册

该初中英语课件围绕“数字技术如何改变生活”核心问题，聚焦议论文写作，主题为互联网对青少年生活的正负面影响。课堂通过小组讨论（如“过多屏幕时间的负面影响”）、实例引导（如日常互联网使用例子）和词汇预习（positive/negative等核心词）导入，以正负面影响列表、写作模板及评价标准为支架，帮助学生构建议论文写作知识脉络。 其亮点在于融合语言能力与思维品质培养，通过“太阳（正面）”“下雨（负面）”比喻及具体实例（如“邻居儿子玩游戏影响成绩”）帮助学生辩证表达观点，运用目标词汇（如allow sb. to do sth.）和第一人称、一般现在时。采用任务驱动（给杂志写段落）与合作学习，提供自查清单（如“用具体例子支撑观点”）提升学习能力。学生能掌握议论文结构与辩证思维，教师可借助系统资源（词汇、模板、评价工具）高效教学。
