Unit 4 Sharing Words and expressions 课件-2025-2026学年高中英语人教版（2019）选择性必修第四册

该高中英语课件聚焦Unit4词汇及表达，系统梳理weed、shade等核心词的释义、派生词及用法，通过真题例句（如浙江卷"jam"的语境应用）、短语拓展（如"in the shade"）和语法练习，构建从基础词形到语境应用的学习支架。 其亮点在于融合高考真题与读后续写场景（如"wrinkle"皱眉动作描写），通过一词多义辨析（如"contract"表合同、签约、感染）提升语言能力，借助对比（drag与pull区分）培养思维品质，助力学生掌握词汇学习策略。学生能提升词汇运用与写作表达，教师可直接用于课堂教学，提高效率。
