UNIT 3 外刊撷英-（配套课件）【学霸笔记·同步精讲】2024-2025学年高中英语必修第三册（人教版）

该高中英语课件围绕“沙漠水资源管理与人类文明发展”核心主题，以“人类生存需水”导入，通过词汇学习（Word Bank、单词列表）、文本阅读（AlUla的地理环境与水管理系统）、单词匹配练习到批判性思维问题，构建从语言输入到输出的学习支架，衔接知识脉络。 其亮点在于融合语言能力、文化意识与思维品质培养。通过词汇表（如“aquifer”“qanats”）和单词匹配夯实语言基础，AlUla案例展现人类适应自然的智慧以培养文化意识，批判性思维问题（如描述少数民族文化）提升思维品质。采用主题式教学，学生提升语言综合运用与跨文化理解，教师获得完整教学资源支持。

AlUla: Mastering the Desert's Water Adapted from National Geographic 202307 　　Humans can survive longer without food than without water, significantly longer. It's one of the harsh realities that makes the dry deserts of Saudi Arabia (沙特阿拉伯) such a challenging place to live. Then there's the searing① heat in a landscape that offers little shade, and the often infertile sands in which plants struggle to grow. It seems an unlikely place for farms, cities, and civilizations to emerge②. 下一页 上一页 外刊撷英 　　But that's what happened in the AlUla valley between the foothills of Saudi Arabia's Hijaz Mountains. Because even in the desert, there are places where water can be found to nurture③ life and allow plants, animals, and humans to thrive. The AlUla valley cradles④ an oasis⑤， an island of habitable⑥ land amid Saudi Arabia's vast seas of sand, a haven⑦ that can support communities. 下一页 上一页 外刊撷英 　　The story of AlUla begins millions of years ago when a wetter climate carved a huge water catchment (汇水) of great valleys that fed the wadi (干谷) that runs through the region. Much of the water flows through underground systems, becoming trapped and stored as an aquifer⑧. Topped up by distant rains, the aquifer raised the water table⑨ close to the surface to create a wetland in which plants could grow, and to this rare source of food and drink flocked animals and, ultimately, humans. AlUla's earliest inhabitants lived a nomadic⑩ 下一页 上一页 外刊撷英 hunter-gatherer lifestyle, perhaps shading beneath trees, and hunting gazelle⑪ while drinking from natural springs⑫ and pooled water at the surface. But AlUla was blessed with⑬ more than water: it also had fertile soils. This enabled later successive⑭ peoples to settle and develop irrigated agriculture, growing crops ranging from palm dates (椰枣) and citrus (柑橘) fruits to wheat and barley (大麦), creating the oasis. 下一页 上一页 外刊撷英 　　In order to sustain an oasis, humans must find, manage, and use the available water wisely. While water bubbling up from natural springs and seasonal rains might temporarily⑮ fill wadis, to make the most of it, people needed to take control of the water. One of the earliest ways was to dig wells. The wells stored vast volumes⑯ of water for long periods, supporting AlUla's people and agriculture. 下一页 上一页 外刊撷英 　　Another sophisticated water-management system emerged: qanats (坎儿井). These gently sloping underground channels tapped into⑰ the water table at a high point, such as at the base of a mountain, and used gravity with a carefully calculated slope to carry the water so that the channel surfaced close to an agricultural plain. AlUla's extensive⑱ network of qanats made it possible to farm large strips of⑲ land. Such major engineering projects, involving immense⑳ collective effort, suggest that improving water supplies was a priority. 下一页 上一页 外刊撷英 　　It's universally recognized today that modern AlUla is still verdant (青翠的) and bountiful， producing 90，000 tons of dates each year. But none of it would be possible without water. In the desolation of the desert, it's millennia of skillful water management that has made AlUla a place of plenty, capable of supporting communities. 下一页 上一页 外刊撷英 ①searing adj.　　 灼热的 ②emerge v. 出现 ③nurture v. 养育；滋长 ④cradle v. 是……的发源地 ⑤oasis n. 绿洲 ⑥habitable adj. 适合居住的 ⑦haven n. 避难所；安全的地方 下一页 上一页 外刊撷英 ⑧aquifer n. 含水层 ⑨water table 　　　　 地下水位 ⑩nomadic adj. 游牧的 ⑪gazelle n. 羚羊 ⑫spring n. 泉，泉水 ⑬be blessed with 有幸享有 ⑭successive adj. 连续的，接连的 ⑮temporarily adv. 暂时地 ⑯volume n. 总量；体积 下一页 上一页 外刊撷英 ⑰tap into 利用；开发 ⑱extensive adj. 广泛的 ⑲large strips of 大块的 ⑳immense adj. 巨大的 collective adj. 共同的 bountiful adj. 丰富的；充裕的 desolation n. 废墟；荒芜 millennium n. 一千年　 下一页 上一页 外刊撷英 than　 challenging　 to emerge　 communities　 when　 becoming　 a　 was blessed　 it　 universally 下一页 上一页 外刊撷英 1．harsh adj.

One possible version： 　　I am keen on the costumes of the ethnic minorities, so I visited an exhibition of ethnic costumes, where various ethnic costumes would be on display, each of them featuring the characteristics of a nationality. While admiring the costumes, I had a better understanding of the customs, culture as well as the history of different nationalities living in our country. 下一页 上一页 外刊撷英 $
