Unit 1 默写练习一 Welcome to the unit，Reading（配套课件PPT）-【步步高】2025-2026学年高二英语选修第二册学习笔记（译林版·新教材）

该高中英语课件围绕“Beware and take care”单元主题，聚焦健康安全相关重点单词、词形变化、核心短语及应用，通过“单词默写—词形填空—短语积累—选词应用”的学习支架，帮助学生构建从词汇记忆到语境运用的知识脉络。 其亮点在于结合语言能力与思维品质培养，单词部分标注词性、词义及派生（如infect的infected、infectious等变形），词形填空通过语境强化词汇变形（如contaminate的动词与名词转换），核心短语提供中英文对照并设计选词填空应用实例。这种结构化练习设计能夯实学生语言基础，提升词汇运用能力，也为教师提供高效的课堂巩固素材。
