Unit 1 Section A2a-2d 听说课公开课课件2025-2026学年人教版英语九年级上册

该初中英语课件围绕“家乡环境变化”核心主题，通过“问题→行动→成果”框架，引导学生运用“used to”和现在完成时等目标语言。课堂导入采用视频观看、图片对比（如Li Rui家乡过去与现在的环境）及猜谜游戏（描述沙尘暴等环境问题让学生猜测），衔接上一课家乡交通、医疗等变化，搭建从已知到未知的学习支架。 其亮点在于任务链设计层层递进，从听力填表（Past-Action-Present表格）到角色扮演（模拟记者采访村民），再到迁移讨论（分析自身家乡变化），结合思维品质（排序环境问题并说明理由）和文化意识（体现政府与人民共同努力的家国情怀）。学生能提升语言运用与逻辑思维能力，教师可获得结构化教学活动及评估工具，便于高效教学。

Must-do Choose-to-do $Long ago, leary's hometown had Sandy hills, bumpy roads. Now great change has happen. IT used to take hours to travel to the city, but now we can take the high speed train. Yes, the hills used to be covered with sand, but now they are covered with Green trees. Imagine a wall, not of stone, but of trees and grass, stretching thousands of kilometers across china. This is the great Green wall, officially called the three north shelter belt forest program, a bold initiative to combat the certification, restore ecosystems, protect homes and lives born from the urgent need to stop desertification. The project began in one thousand nine hundred seventy eight, spending the arid north, northwest and northeast regions of china. The program allocates over four million square kilometers to restoration efforts by twenty fifty IT aims to raise the forest cover rate from five point zero five percent to four two point nine five percent. The Green great wall protects over four hundred million people from the relentless scope desert and fierce dust storms, which threatens not just china, but neighboring countries as well. Over the years, IT face chAllenges, harsh climate, soil degradation and debates over sustainability, yet IT persevere. This project is a marathon, not a sprint, backed by local communities and government support. In its early stages, tree planting became a national mission, and soon millions of people joined in. 通过植树，通过身体力行，让大家体验和潜移默化的有一些生态的和环保的意识，要把这种理念融化到血液里。没有这个全民义务植树的这个等于说我们中国的华南市场这个生态工程建设，我觉得是可能是没有办法实施。Together, they planted over seventy eight point one billion trees in forty years, turning deserts into forest, sand into soil and barn earth into lush, viBrant life. This was more than just a project. IT was a symbol of hope, unity and a shared commitment to the planet. This is china's magic square straws or plant materials arranged in square grids on sand dunes. It's now a global best practice for combating desert encroachment. Alongside the innovative techniques from Ariel seeding to cutting edge, technologies like satellite and AI are shaping the future of desertification prevention, millions of rural residents have been empowered to restore the land through tree planting, forests and fruit based industry. These efforts have not only revived the environment, but also created sustainable livelihoods, lifting countless people out of poverty. Over the past forty six years, over forty five percent of desert fied land has been successfully restored. The project has also provided crucial protection to over thirty million hectares of farmland. However, efforts continue to ensure biodiversity and sustainability. With a deep understanding of natures rythm and the solution tailor to its unique landscapes, china has forced the path to heal the land in its own way. Yet desertification isn't confined to one country. It's a chAllenge we all face. Solving IT will take time, patients and the united effort from assault. I can't believe how much this place has changed, the roads, the hospital, the trees. It's like a whole new world. Seeing how the people here turn problems into progress makes me feel proud of them. 哥哥，说过了，老警员在风里不好，今天是没空，不会下雨去了。透过窗看着那匆匆的季节，总会想起你的昨天，何时能忘却，不怕冰释前嫌。他让我们的爸爸妈妈从城里回来，还说有新技术能让大家一起挣钱。他说你给我站出去，然后。好家庭好。有点小。最后两双是在这些都想看信息，还不新鲜。 There is a saying in china thirty years and heading thirty years in hex I, more than forty years ago, chinese travel mode was Green trains and bicycles, the supply of goods were seriously insufficient, and the payment method was still food stamps. The luxury goods in life for T, V, sets and big brothers. At that time, china's economy was sluggish, the people were poor, and urban ization was backward. Most people lived in the countryside. After the third plenary session of the eleven central committee of the communist party of china, china began to implement a basic national policy of internal reform and opening up to o the outside world. Time is money, and efficiency is the horn of life. Today, more than forty years later, high speed rail, ANY airplanes have become the daily means of transportation for chinese people. Mobile payment has reshape the chinese lifestyle, got rid of the ones poor and backward appearance, and build a well off society in an round way. Beijing, shanghai, guangzhou, taipei, another first year cities shine in the w remember, more than seventy years ago, the old china was in decline with a lot of concessions and was bullied and without dignity. The chinese nation had a low status in the world and despise. Now china has already abandoned the head of the sick man of east asia and stood proudly in the east of the world and strode to the world stage with a ted high.
