Lesson 7 Too late（课件）-2025-2026学年新概念英语第二册

该小学英语课件围绕“Lesson 7 Too late”展开，涵盖重点词汇（如detective, airport）、课文理解及过去进行时语法，通过构词法（air+port=airport）、近义词对比（airfield vs airport）导入，过渡到课文问答练习，再到过去进行时的时间状语和when/while用法，构建词汇-课文-语法的学习支架。 其亮点在于词汇教学结合构词与对比辨析（如steal sth. from...和rob sth. of...），过去进行时通过情境例句（When she knocked, I was bathing）强化理解，助力语言能力和思维品质提升。采用情境教学法，学生能扎实掌握词汇语法，教师可借助结构化内容高效教学。
