九年级英语上册Unit 5 Power of Ideas单元复习系列 任务型阅读专项训练 试题使用说明：阅读内容，取材新颖，紧扣教材，融合时事热点。共设十篇， 前五篇为基础（词数在200左右），后五篇为提升（词数在260词以内）。 Passage 1 （词数：约195） 热点导读： 2026年9月，中国北斗卫星导航系统迎来全球开通六周年。从最初的技术追赶到如今为全球200多个国家和地区提供服务，北斗的成长之路正是中国自主创新的缩影。这一“中国智慧”正在改变世界对导航的认知。 （本题共5个小题，每小题2分，共10分） Beidou: China‘s Star in the Sky Twenty years ago, China relied on foreign navigation systems like GPS. Today, China has its own system — Beidou. The name means “Big Dipper” in Chinese, a constellation that has guided people for thousands of years. Beidou was completed in 2020 and became fully global. By 2026, it provides services to more than 200 countries and regions. It is used in cars, ships, and even farming. Farmers use Beidou to guide their tractors so they can plant seeds in straight lines. This saves time and increases crop production. What makes Beidou special? Unlike GPS, Beidou has a two-way communication feature. Users can not only receive signals but also send messages. This is very useful in emergencies, such as when a ship is lost at sea or when there is an earthquake. Beidou shows the power of creative ideas. It started with a dream — to have China’s own “eyes in the sky.” Today, that dream has come true. As a Chinese scientist said, “Innovation is not about copying others. It is about finding your own path.” Questions: 1. What does the name “Beidou” mean in Chinese? 2. When was Beidou completed and became fully global? 3. How do farmers use Beidou in their work? 4. What is the special feature of Beidou compared with GPS? 5. What did the Chinese scientist mean by saying “Innovation is about finding your own path”? Passage 2 （词数：约198） 热点导读： 2026年“双十一”期间，全国快递业务量再次刷新纪录，当日处理量突破8亿件。这一奇迹的背后，是智能物流系统的强力支撑——从自动分拣机器人到无人配送车，创意与技术正在重新定义“中国速度”。 （本题共5个小题，每小题2分，共10分） The Ideas Behind Fast Delivery Do you remember waiting for weeks to receive a package? That was common ten years ago. Today, in China, many packages arrive within one or two days. Some even arrive on the same day. What made this possible? Creative ideas and new technologies. In 2026, during the “Double Eleven” shopping festival, China’s express delivery system handled over 800 million packages in a single day. That is an amazing number. Behind this speed is a network of smart logistics. Sorting robots work 24 hours a day in huge warehouses. They read barcodes and sort packages at high speed. Unmanned delivery vehicles carry packages to nearby neighborhoods. Drones even deliver to remote mountain villages. The ideas behind these inventions are not always complex. Some are simple but smart. For example, warehouses are designed with a grid system so robots can find the shortest routes. Algorithms predict which goods will be popular and pre-position them closer to customers. These ideas have changed our lives. We now expect things to arrive quickly. As one engineer said, “A good idea doesn’t have to be complicated. It just has to solve a problem.” Questions: 1. How many packages did China‘s express system handle on the “Double Eleven” single day in 2026? 2. What machines work 24 hours in warehouses? 3. How do drones help with delivery? 4. What is an example of a simple but smart idea mentioned in the passage? 5. What did the engineer mean by saying “A good idea doesn’t have to be complicated”? Passage 3 （词数：约202） 热点导读： 2026年8月，中国高铁运营里程突破5万公里，稳居世界第一。从引进技术到自主研发，从“复兴号”到磁悬浮列车，中国高铁的跨越式发展，是创新思维改变国家面貌的最好例证。 （本题共5个小题，每小题2分，共10分） High-Speed Rail: A Journey of Innovation In 2008, China opened its first high-speed rail line between Beijing and Tianjin. The trains ran at about 350 kilometers per hour. Many people were amazed. Today, China has the world’s largest high-speed rail network — over 50,000 kilometers of track by 2026. How did China achieve this so quickly? The answer lies in creative thinking. Instead of simply copying foreign technology, Chinese engineers studied, improved, and innovated. They developed the Fuxing bullet train, which is 100% Chinese-made. It is faster, quieter, and more energy-efficient than earlier models. New ideas also changed how trains are built and operated. For example, engineers use digital twin technology — a virtual copy of the real train system. They test new ideas on the virtual system before using them on real tracks. This saves time and money. High-speed rail has changed China. It connects cities, boosts business, and makes travel easy. But perhaps the greatest change is in people’s minds. As one traveler said, “When I step on a high-speed train, I feel like I’m stepping into the future.” Questions: 1. When did China open its first high-speed rail line? 2. How many kilometers of high-speed rail track did China have by 2026? 3. What is special about the Fuxing bullet train? 4. What is “digital twin technology” and how is it used? 5. What did the traveler mean by saying “I feel like I’m stepping into the future”? Passage 4 （词数：约205） 热点导读： 2026年，中国科学家成功研发出厚度仅为0.015毫米的“手撕钢”，打破国外垄断。这种钢材可以像纸一样被折叠，却比普通钢材坚硬数倍。这一突破性材料将广泛应用于航空航天、柔性显示屏等领域，证明了基础材料创新同样具有改变世界的力量。 （本题共5个小题，每小题2分，共10分） The Steel That Can Be Torn by Hand Imagine a piece of steel that is as thin as paper and can be bent like plastic. It sounds impossible, but Chinese scientists made it happen in 2026. They developed “hand-tearable steel” — a special material only 0.015 millimeters thick. This material is not just thin — it is also extremely strong. It can be folded thousands of times without breaking. It is used in making foldable phones, flexible screens, and even spacecraft parts. Before this invention, China had to buy similar materials from other countries at very high prices. Now, China can produce it independently. The development of hand-tearable steel was not easy. Scientists tested thousands of different formulas and processes. They failed many times, but they never gave up. Finally, they found the right combination of metals and temperature control. This invention shows that great ideas can come from small things. Many people think innovation only happens in high-tech fields like AI or space. But sometimes, it is a tiny piece of material that makes the biggest difference. As one scientist said, “The smallest things often have the greatest power.” Questions: 1. How thick is the “hand-tearable steel” developed by Chinese scientists? 2. What are some uses of this special steel mentioned in the passage? 3. What did China have to do before this invention? 4. What challenges did scientists face in developing this steel? 5. What did the scientist mean by saying “The smallest things often have the greatest power”? Passage 5 （词数：约210） 热点导读： 2026年，一款由中国团队研发的“智能仿生手”获得国际设计大奖。这款假肢不仅能通过肌电信号控制手指动作，还能通过传感器传递触感，让使用者“感受”到物体的软硬。科技不再是冷冰冰的机器，而是有温度的人文关怀。这是创意与善意结合的最佳典范。 （本题共5个小题，每小题2分，共10分） A Hand That Can Feel For people who have lost a hand, simple tasks like holding a cup or tying shoelaces can be very hard. Traditional prosthetics help, but they are often heavy and uncomfortable. In 2026, a Chinese team created a smart bionic hand that changes everything. This bionic hand is special because it can “feel.” Sensors on the fingertips send signals to the user’s brain through the skin, allowing them to sense whether an object is hard or soft, hot or cold. The hand is also controlled by muscle signals — when the user thinks about moving a finger, the hand moves accordingly. The team behind this invention spent five years on research and testing. They used 3D printing to make the hand lighter and cheaper. They also used AI algorithms to make the finger movements more natural. This invention is more than just a piece of technology. It gives people back their independence and dignity. One user said, “This hand doesn’t just hold things — it holds my life together.” The story of the bionic hand shows that creative ideas are most powerful when they are used to help others. Technology is not just about speed or efficiency — it is about humanity. Questions: 1. What makes the smart bionic hand special? 2. How does the user control the movements of the bionic hand? 3. How did the team make the hand lighter and cheaper? 4. How did the user describe the bionic hand? 5. What is the main message of the last paragraph? Passage 6 （词数：约235） 热点导读： 2026年，移动支付在中国已经渗透到城乡的每一个角落，普及率超过90%。从菜市场到寺庙功德箱，从路边摊到顶级商场，二维码无处不在。这一由创意驱动的支付革命，让中国跳过了信用卡时代，直接进入无现金社会，成为全球数字金融的引领者。 （本题共5个小题，每小题2分，共10分） The Magic of the QR Code If you live in China, you use QR codes almost every day. You scan them to pay for food, rent a bike, or check a menu. But have you ever wondered where this simple black-and-white square came from? QR stands for “Quick Response.” It was invented in Japan in 1994 for tracking car parts. The inventor, Masahiro Hara, wanted a code that could be read quickly and hold more information than a barcode. He created the QR code — but he never patented it. He wanted everyone to use it freely. His idea was generous, but it took many years for the QR code to become popular. In China, a company called Tencent saw its potential. They put QR codes into WeChat, and suddenly, paying with a phone became easy. By 2026, over 90% of people in China use mobile payment regularly. Even street vendors and temple donation boxes have QR codes. Why did QR codes succeed in China but not everywhere? The answer is simple: the right idea at the right time. China already had a large population with smartphones, but few people had credit cards. QR codes offered a cheap, fast, and easy way to pay. As one expert said, “A great idea needs not just a good inventor, but also a good moment.” Questions: 1. What does QR stand for? 2. Why did the inventor choose not to patent the QR code? 3. How did WeChat help make QR codes popular in China? 4. Why did QR codes succeed in China but not everywhere else? 5. What did the expert mean by saying “A great idea needs not just a good inventor, but also a good moment”? Passage 7 （词数：约240） 热点导读： 2026年10月，全球最大的“水光互补”发电站在青海正式并网发电。这座电站将光伏发电与水力发电巧妙结合，白天用太阳能，晚上用水能，实现了24小时清洁电力供应。这一创意解决了新能源发电不稳定的世界性难题，是中国智慧对全球能源转型的贡献。 （本题共5个小题，每小题2分，共10分） Harnessing the Sun: China‘s Solar Revolution Imagine a field of solar panels stretching as far as the eye can see. In Qinghai Province, such a field exists — and it has a clever twist. In October 2026, the world’s largest “hydro-solar” power station began operation. It combines solar power with hydropower to solve a big problem: what happens when the sun doesn’t shine? Here is the creative idea. During the day, when the sun is strong, solar panels produce electricity. Some of this electricity is sent to the grid, and some is used to pump water uphill to a reservoir. At night, when there is no sunlight, the stored water is released downhill to generate hydropower. This way, the station provides clean energy 24 hours a day. This idea is brilliant because it solves the biggest challenge of renewable energy — intermittency. Solar and wind power depend on weather and time of day. But with this hybrid system, energy can be stored as water and used whenever needed. China is now a world leader in solar technology. It produces more solar panels than any other country and has built the largest solar farms. But perhaps its greatest achievement is not in size — it is in creative thinking. As one engineer said, “We don’t just want to make more energy. We want to make energy smarter.” Questions: 1. Where is the world’s largest “hydro-solar” power station located? 2. What problem does the “hydro-solar” station solve? 3. How does the station provide energy at night? 4. What does the word “intermittency” mean in the context of this passage? 5. What did the engineer mean by saying “We want to make energy smarter”? Passage 8 （词数：约245） 热点导读： 2026年初，DeepSeek发布新一代大语言模型DeepSeek-R1，以其低成本、高性能和开源特性震惊全球AI圈。仅用600万美元训练成本就达到了国际顶尖水平，打破了大模型必须“砸钱”的行业神话。这一“中国创意”正在重塑全球AI竞争格局。 （本题共5个小题，每小题2分，共10分） DeepSeek: Thinking Different About AI In early 2026, the world of artificial intelligence was shaken by a new name: DeepSeek. This Chinese AI company released a new large language model called DeepSeek-R1. What made it special was not just its performance, but how it was built. Most AI companies spend hundreds of millions of dollars training their models. DeepSeek spent only about $6 million. How did they do it? They used creative thinking. Instead of using the most expensive chips, they found clever ways to use cheaper ones more efficiently. They also designed smarter algorithms that needed less data and less computing power. But the biggest surprise was that DeepSeek made its model open-source. Anyone in the world could download it, study it, and improve it. This is very different from most big tech companies, which keep their AI models secret. DeepSeek’s success shows that innovation is not always about having the most money or the most powerful computers. Sometimes, it is about thinking differently. A young engineer at DeepSeek said, “We didn’t have the biggest budget. We had the biggest ideas.” The company’s name, DeepSeek, means “deep exploration.” It reminds us that true breakthroughs often come from exploring new paths, not just following old ones. Questions: 1. What was special about DeepSeek-R1? 2. How much did DeepSeek spend on training its model? 3. Why was making the model open-source surprising? 4. What did the young engineer mean by saying “We had the biggest ideas”? 5. What does the company name “DeepSeek” mean and what does it suggest? Passage 9 （词数：约250） 热点导读： 2026年，宁德时代发布“换电生态”3.0方案，车主可在2分钟内完成电池更换，比加油还快。这一创意方案通过“车电分离”模式，大幅降低了电动汽车的购买成本和使用焦虑，正在加速新能源汽车的普及。创新的商业模式与技术突破同样重要。 （本题共5个小题，每小题2分，共10分） Swapping, Not Charging: A New Idea for EVs One of the biggest worries for electric car owners is charging. Finding a charging station takes time, and charging the battery takes even longer — often 30 minutes or more. But what if you could change your car’s battery faster than filling a gas tank? That is the idea behind battery swapping. In 2026, CATL, China’s leading battery company, launched its “Battery Swap Ecosystem 3.0.” Drivers can pull into a swap station and have their drained battery replaced with a fully charged one in less than two minutes. It is faster than refueling a gasoline car. How does it work? The stations are automated. A robot lifts the car, removes the old battery, and installs a new one. The whole process is controlled by a computer. Drivers don’t even need to get out of the car. This creative idea also solves another problem: cost. With battery swapping, owners don’t need to buy the battery — they can rent it. This reduces the price of an electric car by 30–40%. It also removes worries about battery aging, because the swap station always provides properly maintained batteries. Of course, there are challenges. Swapping stations cost a lot to build. Different car models need different batteries. But CATL is working on standardized batteries that can fit many car brands. As one business leader said, “Sometimes, the best solution is not to work harder, but to think differently.” Questions: 1. How long does battery swapping take in CATL’s system? 2. How does the swapping process work? 3. How does battery swapping reduce the cost of electric cars? 4. What are the two challenges mentioned for battery swapping? 5. What did the business leader mean by saying “Sometimes, the best solution is not to work harder, but to think differently”? Passage 10 （词数：约258） 热点导读： 2026年12月，工信部发布《5G+工业互联网发展报告》，显示中国已建成5G工厂3000多个，覆盖全部工业大类。从“制造”到“智造”，从“人工作业”到“机器协作”，5G和AI的融合正在催生一场新的工业革命，重新定义“中国制造”的边界。 （本题共5个小题，每小题2分，共10分） The Quiet Factory: When Ideas Build Themselves Walk into one of China’s smart factories today, and you might be surprised. The lights are on, machines are running, but there are very few workers. This is the “lights-out factory” — a factory that runs almost entirely by itself. By the end of 2026, China had built over 3,000 such 5G-connected smart factories. They cover every major industrial category. In these factories, machines talk to each other through 5G networks. AI systems monitor production and make adjustments in real time. Robots move materials, assemble products, and check quality — all without human guidance. What makes this possible? A combination of creative ideas. First, 5G provides super-fast and stable connections, allowing machines to communicate instantly. Second, AI algorithms can predict problems before they happen, preventing downtime. Third, digital twins — virtual copies of the factory — allow engineers to test changes without stopping production. But the real innovation is in how humans and machines work together. Workers no longer do heavy or dangerous jobs. Instead, they manage the systems that run the factory. Their job has changed from physical labor to problem-solving and creativity. This quiet revolution is changing the meaning of “Made in China.” As one factory director said, “A smart factory is not about replacing people. It’s about using ideas to free people to do what they do best — think and create.” Questions: 1. What is a “lights-out factory”? 2. How many 5G smart factories had China built by the end of 2026? 3. What three factors make smart factories possible? 4. How has the workers’ job changed in smart factories? 5. What did the factory director mean by saying “It’s about freeing people to think and create”? 九年级英语上册Unit 5 Power of Ideas单元复习系列 任务型阅读专项训练 解析版答案 Passage 1 — Beidou: China‘s Star in the Sky 1.
