UNIT 2 单元知识回扣（配套Word）-【精讲精练】2026-2027学年高中英语选择性必修第一册教师用书（人教版）

本高中英语讲义围绕单元知识回扣构建学习支架，系统梳理核心词汇（15个附语境例句）、拓展词汇（13个含词性转换）、重点短语（10个）及重点句型（4个含教材原句与仿写），从基础词汇到拓展延伸，再到短语、句型应用，最终通过单元整合短文实现知识综合运用。 该资料以语境化学习为特色，核心词汇配例句助理解，句型仿写结合高考真题（如2022新高考Ⅰ卷场景描写），短文整合单元词汇强化综合表达。既提升语言能力（词汇句型在语境中理解与运用），又培养思维品质（仿写中分析推断），课中辅助教师系统授课，课后帮助学生查漏补缺，巩固知识体系。

Ⅴ.单元词汇整合——背诵下面短文(黑色字体为本单元必备词汇) The instant I learned that we would study through remote education，I resisted the idea because I had a preference for learning at school. Personally，under no circumstances could I have a good command of relevant subjects without teachers' face­to­face instruction available. Hence，at that time I sincerely hoped that the abnormal time would cease as soon as possible. Nevertheless，I persuaded myself into obeying my school's critical rules，with my routine study integrated with the online learning mode. My head teacher constantly reminded us to switch on our electronic appliances in advance. He advocated that we should avoid some potential online dangers，not leak our own private information and pay attention to online security. He strongly opposed us playing computer games. Early on，I could concentrate on what the teachers had laid emphasis on in online classes and take accurate notes so that I could study in an efficient way. Our English teacher told us how to memorize phrases and organize wonderful paragraphs in an essay. Our teachers always kept in touch with us during online learning.
