Unit 2 Topic 2 同步练习-2025-2026学年仁爱科普版英语九年级上册

该初中英语单元学案围绕“环境保护与资源保护”主题，系统设计了Section A至D四个课时的导学任务，通过词汇积累、语法聚焦、语篇理解与语言输出层层递进，构建从知识输入到能力输出的完整学习路径。每课时均设置明确的学习目标和结构化预习活动，如短语划记、句子翻译与语法点拨，帮助学生在真实语境中理解并运用不定代词、动词短语及环保相关表达，体现语言能力与思维品质的协同发展。 亮点在于以“绿色校园行动”为项目主线，融合文化意识与学习能力培养，例如Section B中的书面表达任务要求学生撰写校广播站倡议书，引导学生用英语提出环保建议，增强社会责任感；Section C阅读理解则通过对比过去与现在污染问题，激发批判性思考，提升思维品质。学案还嵌入语法归纳表、错题整理区等复习工具，助力学生自主建构知识体系，既支持学生深度学习，也为教师开展大单元教学提供清晰的教学支架与实施路径。

Factories must now clean their water before it is poured into rivers; they mustn't blow dirty smoke into the air.        We need to do many other things. We can put waste things in the dustbin instead of throwing it on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution. Rules are not enough. Every person must help to fight pollution. 1. Hundreds of years ago, life was much harder than it is today because ____ .      A. there were not any modern machines      B. there was no pollution      C. both A and B      D. there were not many people    2. What is the biggest problem in today's life?     ___         .
