Unit 1 课时2 Section A 2a-3d（教学课件）英语新教材鲁教版九年级全一册

该初中英语课件围绕“发明的力量”主题，聚焦3D打印、收音机等发明的听说训练，涵盖被动语态核心词汇。课堂导入通过复习旧课发明，结合“What does it look like? What is it used for?”等问题，搭建旧知到新知的学习支架。 其亮点在于采用任务驱动式听说活动，如听力抓取3D打印流程和收音机发明信息，3d环节让学生绘制思维导图并用模板描述发明，语言点对比辨析invent与discover等词汇。这一设计提升学生语言能力和思维品质，帮助教师高效开展结构化教学，助力学生掌握听说策略与知识运用。
