Unit 7 Section A（2a～2e）课件- 2025-2026学年鲁教版五四制英语七年级上册

该初中英语课件围绕“居家安全”主题，核心知识点包括祈使句、情态动词运用及安全规则。通过“Look and find”让学生观察图片找出潜在危险，如燃烧的烟头、私拉乱接电线等，再结合“Look and guess”推测Peter与父母的对话主题，过渡到听力理解居家安全对话，进而学习祈使句和“make sure to+动词原形”等语法点，为演讲任务搭建支架。 其亮点在于融合语言能力与思维品质培养，通过图片观察分析危险隐患（如抽油烟机油脂过多、易燃物靠近炉灶），引导学生用祈使句和情态动词描述安全规则，最终完成“保持居家安全”演讲，体现任务型教学从输入到输出的递进。采用“Summary”梳理对话要点并附评分表格，学生提升语言运用与安全意识，教师可依托结构化任务链高效教学。
