Beekeepers are helping to protect the forest while earning a living. Their secret weapon? Stingless bees. For generations, local people in the Amazon have collected honey from native stingless bees. These bees are smaller than honeybees and produce less honey, but they play a crucial role in the forest. They pollinate plants, helping the rainforest to thrive. In recent years, deforestation has threatened the Amazon. Farmers cut down trees to create pasture for cattle. But beekeeping offers an alternative. “When I was young, everyone wanted to cut down trees for farming,” said beekeeper Carlos Silva. “Now we see that keeping bees is better. The forest stays standing, and we still make money.” Beekeeping provides income without destroying the forest. Families sell honey, wax, and even the bees themselves to other farmers who want to start their own hives. Women in the community have become leaders in honey production. Scientists have studied the impact of beekeeping on forest conservation. They found that areas where beekeeping is practiced have lower rates of deforestation. When bees are valuable, the trees that provide their flowers become valuable too. “The bees are teaching us something important,” said Maria Santos, a beekeeper who now trains others. “We don’t have to choose between making a living and protecting nature. We can do both.” The success of Amazon beekeeping has inspired similar projects in Africa and Southeast Asia. As one expert noted, “Sometimes the smallest creatures can help solve the biggest problems.” Core Vocabulary stingless /ˈstɪŋləs/ adj. 无刺的 pollinate /ˈpɒləneɪt/ v. 授粉 deforestation /diːˌfɒrɪˈsteɪʃən/ n. 森林砍伐 pasture /ˈpɑːstʃə/ n. 牧场 conservation /ˌkɒnsəˈveɪʃən/ n. 保护 Comprehension Questions 1.

Their secret is an ancient water system called cannot can. Nets are underground channels that Carry water from mountains to farms in villages. They were first built over three thousand years ago, and many are still in use today. Engineers consider them one of the greatest achievements of ancient technology. Building a canet required incredible skill. Workers dog vertical shafts from the surface down to the water table. Then they connected these shafts with a gently sloping tunnel. The tunnel Carried water by gravity without any pumps. Our ancestors understood this land Better than anyone, said his son, mohd, a farmer whose family has used the same cannet for eight generations. They knew that water must travel underground to avoid the desert heat. Today, climate change is making water even more precious. Many modern irrigation systems waste water through evaporation, but can its lose almost none. In recent years, there has been renewed interest in this ancient technology. Engineers from around the world have come to study the cannet. Some countries, including spain in mexico, are building modern versions of these underground channels. All doesn't mean outdated.

They create floating gardens. For centuries, farmers in this South Asian nation have used water hyacinths to build floating rafts. They collect the plants, let them dry slightly, and then layer them together to form a platform. On these floating beds, they grow vegetables like spinach, eggplant, and pumpkins. “When the floods come, our land disappears under water,” explained farmer Muhammad Islam. “But our gardens float. We don’t lose our crops.” The floating gardens do more than just provide food. They also create jobs for women in rural communities. Women help build the rafts and harvest the vegetables, earning money for their families. Climate change has made flooding more severe in Bangladesh. Sea levels are rising, and storms are becoming stronger. For many farmers, floating gardens are no longer just a tradition—they are a necessity. Scientists from around the world have come to study these gardens. They believe the technique could help farmers in other flood-prone countries, such as Vietnam and Myanmar. “This is traditional knowledge that is becoming more valuable every year,” said Dr. Amina Rahman, a researcher from Dhaka University. “The farmers figured out how to live with nature instead of fighting against it.” Today, more than 100,000 families in Bangladesh use floating gardens. The government is helping to spread the technique to other regions. As one farmer put it, “The water used to be our enemy. Now we have learned to make it our friend.” Core Vocabulary flood /flʌd/ n. 洪水 water hyacinth /ˈwɔːtə ˈhaɪəsɪnθ/ n. 水葫芦 raft /rɑːft/ n. 筏；浮台 platform /ˈplætfɔːm/ n. 平台 necessity /nəˈsesəti/ n. 必需品；必要的事物 Comprehension Questions 1.

Their secret is an ancient water system called qanat. Qanats are underground channels that carry water from mountains to farms and villages. They were first built over 3,000 years ago, and many are still in use today. Engineers consider them one of the greatest achievements of ancient technology. Building a qanat required incredible skill. Workers dug vertical shafts from the surface down to the water table. Then they connected these shafts with a gently sloping tunnel. The tunnel carried water by gravity, without any pumps. “Our ancestors understood this land better than anyone,” said Hassan Mohammadi, a farmer whose family has used the same qanat for eight generations. “They knew that water must travel underground to avoid the desert heat.” Today, climate change is making water even more precious. Many modern irrigation systems waste water through evaporation. But qanats lose almost none. In recent years, there has been renewed interest in this ancient technology.

Stella原创资料 学科网（北京）股份有限公司 $ 外研版八下拓展阅读Unit6 Reading 1: The Floating Gardens of Bangladesh 参考译文 在频繁发生洪水的孟加拉国，农民们找到了一种巧妙的方法，即使土地被水淹没也能种植食物。他们创造了漂浮花园。 几个世纪以来，这个南亚国家的农民一直使用水葫芦来建造漂浮筏。他们收集这种植物，让其稍微干燥，然后将它们层层叠放在一起形成一个平台。在这些漂浮的苗床上，他们种植菠菜、茄子和南瓜等蔬菜。 “洪水来临时，我们的土地消失在水下，”农民穆罕默德·伊斯兰解释道。“但我们的花园漂浮在水上。我们不会失去庄稼。” 漂浮花园不仅仅提供食物。它们还为农村社区的妇女创造了就业机会。妇女们帮助建造筏子、收割蔬菜，为家庭赚钱。 气候变化使孟加拉国的洪水更加严重。海平面在上升，风暴变得更加强烈。对许多农民来说，漂浮花园不再仅仅是一种传统——它们成了一种必需品。 来自世界各地的科学家前来研究这些花园。他们认为这项技术可以帮助其他易受洪水侵袭国家的农民，如越南和缅甸。 “这是一项每年都变得更加宝贵的传统知识，”达卡大学的研究员阿米娜·拉赫曼博士说。“农民们想出了如何与自然共存，而不是与自然抗争。” 如今，孟加拉国有超过10万个家庭使用漂浮花园。政府正在帮助将这项技术推广到其他地区。正如一位农民所说：“水曾经是我们的敌人。现在我们学会了让它成为我们的朋友。” 题目解析 第1题 正确答案是B。这道题考查细节理解。文章第一段明确指出孟加拉国“experiences frequent floods”，农民在“land is underwater”时仍要种植食物，因此农民面临的主要问题是土地频繁被洪水淹没，这与选项B的描述一致。A说没有足够的土地耕种、C说土壤太干无法种植蔬菜、D说缺少劳动力，文中均未提及。 第2题 正确答案是B。这道题考查细节理解。文章第二段详细描述了漂浮花园的建造方法：“use water hyacinths to build floating rafts”，即使用水葫芦建造漂浮筏，这与选项B的描述一致。A说在水上建造木质平台、C说直接在河里种菜、D说把田地里的水抽走，都不是文中描述的方法。 第3题 正确答案是C。这道题考查词义猜测。文章第五段说对许多农民来说，漂浮花园“are no longer just a tradition—they are a necessity”，结合前文气候变化使洪水更严重，农民需要靠漂浮花园生存，因此“necessity”意为“必要的事物”。其他选项A“传统”、B“奢侈品”、D“实验”都不符合语境。 第4题 正确答案是B。这道题考查细节理解。文章第四段说明漂浮花园除了提供食物外，“create jobs for women in rural communities”，即为农村社区的妇女创造就业机会，这与选项B的描述一致。A说帮助控制洪水、C说吸引游客、D说改善水质，文中均未提及。 第5题 正确答案是B。这道题考查细节理解。文章第七段拉赫曼博士评价道：“The farmers figured out how to live with nature instead of fighting against it”，即农民们想出了如何与自然共存而不是与自然抗争，这与选项B的描述一致。A说这是不再有用的古老技术、C说政府应该停止支持这一传统、D说只有孟加拉国能使用这种方法，都与博士的话不符。 Reading 2: How Beekeepers Are Saving Forests 参考译文 在巴西的雨林中，一场静悄悄的革命正在发生。养蜂人一边保护森林，一边谋生。他们的秘密武器是什么？无刺蜜蜂。 几代人以来，亚马逊地区的当地人一直在从本土无刺蜜蜂身上采集蜂蜜。这些蜜蜂比普通蜜蜂小，产蜜量也更少，但它们在森林中扮演着至关重要的角色。它们为植物授粉，帮助雨林繁茂生长。 近年来，森林砍伐威胁着亚马逊地区。农民们砍伐树木来开辟牧场养牛。但养蜂提供了一种替代选择。 “我年轻的时候，每个人都想砍树来种地，”养蜂人卡洛斯·席尔瓦说。“现在我们看到养蜂更好。森林保住了，我们仍然能赚钱。” 养蜂在不破坏森林的情况下提供了收入。家庭出售蜂蜜、蜂蜡，甚至把蜜蜂本身卖给其他想开始养蜂的农民。社区中的妇女已成为蜂蜜生产的领导者。 科学家们研究了养蜂对森林保护的影响。他们发现，在养蜂实践的地区，森林砍伐率较低。当蜜蜂有价值时，为它们提供花朵的树木也变得有价值了。 “蜜蜂在教我们一些重要的东西，”玛丽亚·桑托斯说，她是一名养蜂人，现在也在培训其他人。“我们不必在谋生和保护自然之间做出选择。我们可以两者兼得。” 亚马逊养蜂的成功启发了非洲和东南亚的类似项目。正如一位专家所说：“有时候最小的生物能帮助解决最大的问题。” 题目解析 第1题 正确答案是B。这道题考查细节理解。文章第二段明确指出当地人使用“native stingless bees”，即本土无刺蜜蜂，这与选项B的描述一致。A说从欧洲引进的蜜蜂、C说杀人蜂、D说大黄蜂，文中均未提及。 第2题 正确答案是B。这道题考查细节理解。文章第四段卡洛斯解释说养蜂更好因为“The forest stays standing, and we still make money”，即森林保住了，还能赚钱，第五段进一步说明养蜂“provides income without destroying the forest”，这与选项B的描述一致。A说蜜蜂吓跑砍树的人、C说蜜蜂吃掉农民想砍的树、D说养蜂需要农民种更多树，都不是文中描述的原因。 第3题 正确答案是B。这道题考查词义猜测。文章第三段说“deforestation has threatened the Amazon”，结合上下文，森林砍伐对亚马逊造成了负面影响，因此“threatened”意为“威胁”。其他选项A“保护”、C“帮助”、D“忽视”都不符合语境。 第4题 正确答案是B。这道题考查细节理解。文章第六段明确说明科学家发现“areas where beekeeping is practiced have lower rates of deforestation”，即养蜂实践的地区森林砍伐率较低，这与选项B的描述一致。A说砍伐率更高、C说生产更多牛、D说蜜蜂种类更少，都与文中描述相反。 第5题 正确答案是C。这道题考查细节理解。文章第七段玛丽亚说“We don’t have to choose between making a living and protecting nature. We can do both”，即不必在谋生和保护自然之间选择，可以两者兼得，这与选项C的描述一致。A说人们应该在谋生和保护自然之间做选择、B说保护自然比赚钱更重要、D说养蜂对大多数人来说太难，都不是她的观点。 Reading 3: The Ancient Water System That Still Works 参考译文 在降雨稀少、气温极高的伊朗沙漠中，人们已经生活了数千年。他们的秘密是一种叫做坎儿井的古老水利系统。 坎儿井是地下渠道，将水从山脉输送到农田和村庄。它们最早建于3000多年前，许多至今仍在使用。工程师们认为它们是古代技术最伟大的成就之一。 建造坎儿井需要令人难以置信的技术。工人们从地面向下挖掘竖井，直达地下水位。然后用一个平缓倾斜的隧道将这些竖井连接起来。隧道利用重力输水，不需要任何水泵。 “我们的祖先比任何人都了解这片土地，”哈桑·穆罕默迪说，他的家族已经连续八代使用同一口坎儿井。“他们知道水必须在地下流动，以避免沙漠的高温。” 如今，气候变化使水变得更加宝贵。许多现代灌溉系统通过蒸发浪费水。但坎儿井几乎不损失水。 近年来，人们对这项古老技术的兴趣重新燃起。来自世界各地的工程师前来研究坎儿井。包括西班牙和墨西哥在内的一些国家正在建造这些地下通道的现代版本。 “古老并不意味着过时，”水资源专家莱拉·侯赛尼博士解释道。“坎儿井系统告诉我们，最可持续的解决方案往往来自与自然合作，而不是与之对抗。” 联合国已将坎儿井认定为世界遗产的重要组成部分。正如一位当地长者所说：“水可能在地下流淌，但它的重要性贯穿我们所做的一切。” 题目解析 第1题 正确答案是B。这道题考查细节理解。文章第一段和第二段说明坎儿井是“underground channels that carry water from mountains to farms and villages”，即从山脉向农田和村庄输水的地下渠道，这与选项B的描述一致。A说一种饮用水井、C说从地下深处抽水的机器、D说储存雨水的传统方法，都不符合定义。 第2题 正确答案是B。这道题考查细节理解。文章第三段说明坎儿井如何不用水泵输水：“a gently sloping tunnel... carried water by gravity”，即一个平缓倾斜的隧道利用重力输水，这与选项B的描述一致。A说使用太阳能、C说工人用桶运水、D说风车把水抽到地面，都不是文中描述的方式。 第3题 正确答案是C。这道题考查词义猜测。文章第五段说“climate change is making water even more precious”，结合上下文，气候变化使水更稀缺、更重要，因此“precious”意为“宝贵的”。其他选项A“昂贵的”、B“稀有的”、D“清澈的”都不够准确。 第4题 正确答案是B。这道题考查细节理解。文章第五段将坎儿井与现代灌溉系统对比：“Many modern irrigation systems waste water through evaporation. But qanats lose almost none”，即现代灌溉系统通过蒸发浪费水，而坎儿井几乎不损失水，这与选项B的描述一致。A说建造成本更低、C说可以在任何地方建造、D说提供更多水，文中均未提及。 第5题 正确答案是B。这道题考查细节理解。文章第七段侯赛尼博士说“the most sustainable solutions often come from working with nature, not against it”，即最可持续的解决方案往往来自与自然合作，而不是与之对抗，这与选项B的描述一致。A说坎儿井过时应该被取代、C说只有伊朗能使用这项技术、D说现代水泵比坎儿井更好，都与博士的话不符。 Reading 4: The Young Inventor Who Turns Plastic into Homes 参考译文 17岁的大卫·森格访问他的祖国塞拉利昂的一个村庄时，看到了一些让他困扰的事情。家庭住在用泥土和树枝搭建的房子里。雨季来临时，许多这样的房子被冲走。 大卫想要帮忙，但他知道混凝土等传统建筑材料对大多数家庭来说太贵了。他开始思考：有没有更便宜的方法来建造坚固的房子？ 答案来自一个意想不到的来源：塑料垃圾。大卫注意到塞拉利昂的街道和海滩上到处都是塑料瓶。这些瓶子可以用来盖房子吗？ 经过几个月的实验，大卫开发出了一种方法。他和他的团队收集塑料瓶，清洗干净，然后装满沙子。接着他们把瓶子像砖头一样堆叠起来，再用泥土或水泥覆盖。结果是一堵比传统泥砖更坚固、成本几乎为零的墙。 “塑料瓶到处都是，”大卫解释道。“人们过去把它们看作垃圾。现在我们把它们看作建筑材料。” 大卫的想法已经流行开来。用他的方法已经建造了200多所房屋。这些房屋防水，能安然度过雨季，而且在炎热天气下还能保持凉爽。 这个项目还帮助清理了环境。超过10万个塑料瓶已从街道和海滩上被清除。当地人通过收集瓶子赚钱。 “大卫向我们展示了，解决问题的办法就在我们眼前，”社区领袖法蒂玛·卡马拉说。“我们只是需要以不同的眼光看待它。” 大卫希望将他的项目扩展到面临类似挑战的其他国家。“自然给我们问题，但也给了我们解决问题的材料，”他说。“我们只需要发挥创造力。” 题目解析 第1题 正确答案是B。这道题考查细节理解。文章第一段描述了大卫在塞拉利昂看到的问题：“Families were living in homes made of mud and sticks. When the rainy season came, many of these homes washed away”，即家庭住在泥土和树枝搭建的房子里，雨季时许多房子被冲走，这与选项B的描述一致。A说家庭没有干净饮用水、C说孩子没有学校上、D说工厂污染河流，文中均未提及。 第2题 正确答案是C。这道题考查细节理解。文章第四段描述了大卫的建房方法：收集塑料瓶，装满沙子，像砖头一样堆叠，用泥土或水泥覆盖，因此他使用“plastic bottles filled with sand”作为建筑材料，这与选项C的描述一致。A说混凝土和钢材、B说木材和金属、D说泥土和树枝，都不是他使用的主要材料。 第3题 正确答案是B。这道题考查词义猜测。文章第三段说答案来自“an unlikely source: plastic waste”，塑料垃圾通常不被认为是建筑材料，因此这个来源是意想不到的，所以“unlikely”意为“意想不到的”。其他选项A“不可能的”、C“昂贵的”、D“普通的”都不符合语境。 第4题 正确答案是B。这道题考查细节理解。文章第五段和第六段说明瓶装房屋的优势：“waterproof, survive the rainy season, and even stay cooler in the heat”，即防水、能安然度过雨季、在炎热天气下保持凉爽，这与选项B的描述一致。A说昂贵但耐用、C说需要难以找到的特殊材料、D说只有专家才能建造，都与文中描述相反。 第5题 正确答案是A。这道题考查主旨理解。文章最后一段大卫总结道：“Nature gives us problems, but it also gives us the materials to solve them. We just have to be creative”，即自然给我们问题，但也给了我们解决问题的材料，我们只需要发挥创造力，这与选项A的描述一致。B说只有成年人能解决社区问题、C说建造房屋对年轻人来说太难、D说塑料垃圾应该扔掉，都不是大卫传达的信息。 学科网（北京）股份有限公司 $外研八下时文阅读 Unit6时文阅读全能训练四 拓展阅读 建议作答时间：10分钟 姓名： 评价： The Young Inventor Who Turns Plastic into Homes Adapted from CNN When 17-year-old David Sengeh visited a village in his home country of Sierra Leone, he saw something that troubled him. Families were living in homes made of mud and sticks. When the rainy season came, many of these homes washed away. David wanted to help, but he knew that traditional building materials like concrete were too expensive for most families. He started thinking: was there a cheaper way to build strong homes? The answer came from an unlikely source: plastic waste. David noticed that the streets and beaches of Sierra Leone were filled with plastic bottles. Could these bottles be used to build homes? After months of experiments, David developed a method. He and his team collect plastic bottles, clean them, and fill them with sand. Then they stack the bottles like bricks and cover them with mud or cement. The result is a wall that is stronger than traditional mud brick and costs almost nothing. “The plastic bottles are everywhere,” David explained. “People used to see them as trash. Now we see them as building materials.” David’s idea has caught on. More than 200 homes have been built using his method. The homes are waterproof, survive the rainy season, and even stay cooler in the heat. The project has also helped clean up the environment. Over 100,000 plastic bottles have been removed from streets and beaches.

How beekeepers are saving forests in the rainforest of brazil, a quiet revolution is taking place. Beekeepers are helping to protect the forest while earning a living. Their secret weapon, stingless bees. For generations, local people in the amazon have collected honey from native ingles bees. These bees are smaller than honey bees and produce less honey, but they play a crucial role in the forest. They pollinate plants, helping the ryan forest to thrive. In recent years, deforestation has threatened the amazon. Farmers cut down trees to create pasture for cattle. But beekeeping offers an alternative. When I was Young, everyone wanted to cut down trees for farming, said beekeeper carlo silva. Now we see that keeping bees is Better, the first stay standing, and we still make money. Beekeeping provides income without destroying the forest family, sell honey, wax and even the bees themselves to other farmers who want to start their own hives. Women in the community have become leaders, and honey production scientists have studied the impact to be keeping on force conservation. They found that areas where beekeeping as practice have lower rates of deforestation. When bees are valuable, the trees that provide their flowers become valuable to the bees are teaching us something important, said mario santa S, A beekeeper who now trains others. We don't have to choose between making a living and protecting nature. We can do both. The success of amazon beekeeping has inspired similar projects in africa and southeast asia. As one expert noted, sometimes the smallest creatures can help solve the biggest problems. The Young inventor who turns plastic into homes when seventeen year old David sange visited a village in his home country of c. Leon, he saw something that troubled him. Families were living in homes made of modern sticks. When the rainy season came, many of these homes washed away. They had wanted to help, but he knew that traditional building materials like concrete, were too expensive for most families. He started thinking, was there a cheaper way to build strong homes? The answer came from an unlikely source, plastic ways. David noticed that the streets and beaches of c alion were filled with plastic bottles. Could these bottles be used to build homes? After months of experiments, David developed a method. He and his team collect plastic bottles, clean them and filled them with sand. Then they stack the bottles like bricks and cover them with murder cement. The result is a world that is stronger than traditional mud break and costs almost nothing. The plastic bottles are everywhere, David explained. People used to see them as trash. Now we see them as building materials. David's idea has caught on. More than two hundred homes have been built using his method. The homes are waterproof, survive the rainy season and even stay cooler in the heat.
