Scientists at Landuo Biotech, a business in Wuhan, have created one such plant recently. They name it “super giant reed”(超级芦竹).#2 Since 2012, the Landuo team have collected over 1,000 wild giant reeds for experiments. As a result, more than 40 varieties of super giant reed have been “born”. In the Landuo's factory, hundreds of young reeds are grown in glass bottles. Fully grown, super giant reeds are cut and put in a special place without O2 . The Landuo team heat them up to make natural gas, which can then be used for energy. 9 Thanks to the scientists' efforts, super giant reed has a biomass (生物量) three times that of wild giant reed. A kilogram of super giant reed also has 4,000 to 4,500 kilocalories(千卡) of energy. So, super giant reed is a great choice for taking the place of fossil fuels(化石燃料). What's more, growing super giant reed helps a lot. Planting 13,000 hectares of it can produce 0.45 to 1.5 million tons of fuel a year. 40 million hectares of super giant reed can be used instead of 2.2 billion (1 billion=1,000 million) tons of coal and can cut CO2 emissions(排放) by 4 billion tons in China every year. 10 What's more, growing super giant reed helps a lot.

Super giant reed is also well-suited for growing on some land like beaches, wetlands and salty lands. Once a reed is planted, it can be cut and used many times during the next 15 to 20 years. By the end of 2024, over 3,300 hectares of super giant reed had been planted across 53 areas in China. At present, China is developing this new energy source—super giant reed and we hope that it can help to make our planet cleaner and cleaner.#7 【主旨大意】文章主要介绍了科学家们创造的一种可以用来制造绿色能源 的新型植物——超级芦竹。详细介绍了超级芦竹的培育过程、对环境的帮 助作用、合适的生长环境及目前中国的种植情况。 13 1.

Over time, prices are likely to fall enough for the home market, changing how we live and eat. Convenience can come at a great cost, so it's important to look ahead at the possible changes AI kitchens will bring. Undoubtedly, AI kitchens will bring great benefits. For example, it can take over boring tasks like peeling potatoes, letting people focus on creating new dishes. With AI kitchens, busy families will gain free time 21 to spend together or finish important work. What's more, it can help people eat more healthily, like cutting down on sugar. However, cooking is more than just making food. It helps us feel grateful, creative, and connected. For example, when parents and kids cook together, they share stories and learn from each other. Without this, mealtimes might be less meaningful. Children will also miss out on learning science and math through cooking like measuring the ingredients(食材) or watching bread rise. While AI can help with creativity, there are risks to culture. If robots only use popular ingredients, unique(独特的) local dishes may disappear. Also, can you imagine AI kitchens quietly erase(抹去) the joy of sharing home-cooked meals with neighbors? What worries us most is that these smart machines sometimes are not so smart. We're not sure if they can find out the food that has gone bad to avoid accidents. What if a robot serves rotten(腐烂的) fruit because it can't smell? Who would be responsible if a robot makes someone sick or gets hacked? These questions are as unclear as with self-driving cars. The kitchen is a special place in homes, neighborhoods and cultures. We should use robots wisely—having them do boring and challenging jobs rather than allowing them to take the lead. This way, we can enjoy progress without losing the traditional cultures.【推荐背诵】#6 【主旨大意】文章主要介绍了人工智能厨房的现状，分析了其好处如承担 枯燥任务、助力健康饮食等，以及其在文化、安全等方面可能存在的问题。 1.Why does the author mention “Convenience can come at a great cost” in Paragraph 1?

Scientists have created a brain-spinal chip(芯片) that allows paralyzed(瘫痪的) patients to move their legs, and even walk again. The chip, only 1 mm wide, is designed to be fitted into the brain and spinal cord. If the natural communication between the brain and muscles(肌肉) is lost, this chip becomes the bridge. When the chips work, they create a direct connection between the brain and muscles. 31 The results have been amazing. A 34-year-old man, paralyzed after a fall, could move his legs just one day after the operation on January 8, 2025. Two weeks later, he walked five meters with help. Three other patients had similar operations in February and March, all getting better within weeks. Even though the patients' nervous systems were damaged(受损), the chips helped them walk again. This marks a big step in China's progress in medical science and it brings hope for over 3.7 million people in China. “This is just the beginning,” Jia, the lead researcher says. “With the technology, these people may one day leave wheelchairs behind after 3 to 5 years of training.” Behind this achievement is a long journey of careful research and bold thinking. It took the researchers over 10 years to develop the chip. They tested it on animals first, and then on people. They faced many challenges, yet they never gave up. Gradually, they developed a system to reconnect the mind and body in ways once appearing only in science fiction.#5 As the chip continues to improve, it lights a new path forward—one built on science, shaped by care, and aimed toward a brighter future.#6 34 【主旨大意】文章主要介绍了中国科学家研发的一种脑脊髓芯片如何帮助 脊髓损伤患者恢复行走能力的情况，标志着中国在医学科学领域的重大进 步，为数百万患者带来新的希望。 1.What do we know about the chips mentioned in the text?

Over 20% of its colorful paintings are cracking(裂开) or losing colors because of weather and visitors. Some grottoes are now closed for protection. But don't worry! High-tech tools are working together to “help” these cultural wonders. Small flying robots with cameras are used to find tiny cracks. AI studies old painting methods to guess the colors of faded(褪色) areas. Robots use super-thin glue to repair the cracks carefully—like fixing a butterfly's wing. Broken temple parts are rebuilt using 3D printers. 53 But technology isn't just for experts! A company called Sense Time used AR and AI to bring old paintings to life. You can “walk” inside the paintings on your mobile phone. They also made digital artworks from other famous works in China, like horses drawn by Xu Beihong and art from the Dunhuang Grottoes. Another fun game is called “100 Scenes of Jiangnan”. People can experience “real” Ming Dynasty's social life and art in it. For example, the game has a special kind of art from the Ming Dynasty, called Luodian lacquerware (螺钿漆器). Ancient artists put pretty shells(贝壳), gold and silver on it. In the game, players can make their own digital one. They can add flowers, birds and characters, just like the artists did in the old days. However, some people worry： Will old repair skills disappear? Can screens replace the magic of seeing real paintings? Researcher Li Xia says, “Technology saves the past, but love keeps it alive.” The best way to protect history isn't just with machines—it's by inspiring(鼓舞) young hearts to care.#1.2 【主旨大意】文章主要介绍了高科技如何帮助保护敦煌莫高窟等文化遗产， 以及如何通过科技手段让公众近距离体验“真实的”古代生活与文化。 1.How are broken temple parts rebuilt? _____________________ By using 3D printers. 2.What can the robots with cameras be used in cultural wonders? ____________________ Finding tiny cracks. 3.Why are some grottoes' colorful paintings cracking or losing colors? _______________________________ Because of weather and visitors. 57 4.As middle school students, what can we do to protect our cultural wonders?
