Unit 1 SectionB 1a-1f 课件 2026-2027学年人教版英语九年级上册

该初中英语课件围绕“肯尼亚火车系统的变化”展开，通过“Did things change?”等问题导入，引导学生观察新旧铁路在时间、速度、影响上的对比，搭建从现象到本质的学习支架。 其亮点在于通过数据（如1901年旧铁路、2017年新铁路）、事实（当地人生活改善）和观点（国际合作意义），培养学生分析比较的思维品质，渗透人类命运共同体的文化意识。语言点讲解（如link用法、It takes句型）提升语言能力，学生在探究中学会解决问题，教师可依托结构化活动提高教学效率。

It now takes about 10 hours to travel between the two cities by train. The railway not only connects the two cities as well as the two countries more closely, but also makes a big difference in local people's lives. It provides people in Laos with more than 110,000 jobs. Discuss the questions 2. In what other ways can China work together with other countries to build a better world? China can work with other countries in many ways to build a better world. First, China can help build more roads, hospitals and schools in developing countries. Second, China can share new technologies, like farming methods, with other countries. Third, China can work with other countries on environmental protection. Finally, China can provide cultural exchanges, like student exchange programs, to help people from different countries understand each other better. Homework $
