Name & Country Comments Marco (Italy)​ My city Rome has a history of over 2,500 years. In the past, the traffic was always heavy and the air was polluted. But now, the government has built many new cycle lanes and encouraged people to use electric buses. The historic center has been closed to private cars, so the air is much cleaner and it's easier to walk around the ancient ruins. Yuki (Japan)​ I live in Tokyo. The public transport here is amazing. We have the Shinkansen (bullet train) which can run at 320 km/h. It's always on time. Also, many people use the subway. To reduce overcrowding, the government has introduced flexible working hours. Now, fewer people travel during the rush hour, so the trains are more comfortable. Ahmed (Egypt)​ Cairo used to have only two old metro lines. But last year, the third line was completed with the help of Chinese companies. It uses advanced Chinese trains and technology. Now, it takes me only 20 minutes to get to school instead of an hour. The new metro stations are clean, safe and have beautiful designs showing Egyptian culture. Zhang Wei (China)​ My hometown Chengdu has changed a lot. We now have 14 subway lines and the Tianfu International Airport. The subway connects every corner of the city, and the airport has direct flights to many countries. High-speed trains can take us to Beijing in about 7 hours. The transport development makes our life faster and more convenient. 46．What did the government in Rome do to improve traffic? A．Built more highways for cars. B．Closed the historic center to private cars. C．Encouraged people to drive electric cars. 47．How does Yuki's government reduce overcrowding on trains? A．By building more subway lines. B．By introducing flexible working hours. C．By increasing ticket prices. 48．Who mentioned the help of Chinese companies in transport development? A．Marco. B．Yuki. C．Ahmed. 49．How many subway lines does Chengdu have according to Zhang Wei? A．2. B．14. C．20. 50．What is the main idea of the four comments? A．Transportation development in different places. B．The history of trains in different countries. C．How to build a subway system. B Smart Water-Saving System Wins Youth Award A team of three middle school students from Shenzhen won the first prize in a national youth innovation competition with their smart water-saving system for homes. The system uses sensors to detect water leaks and automatically reuses washing machine water for flushing toilets. It can save up to 30% of daily household water. The idea came from their geography teacher who told them about water shortage in some parts of China. The students spent six months designing and testing the system. They hope to cooperate with a company to produce it for ordinary families. Green Roofs Cool Down Cities Many cities in China are now building "green roofs" — roofs covered with plants. These roofs can reduce the temperature inside buildings by up to 6°C in summer, cutting the need for air conditioners. They also absorb rainwater, reducing the risk of floods. In Shanghai, a new regulation requires all new public buildings to have green roofs. Experts say if 20% of a city's roofs were green, the urban temperature could drop by 1°C. This is a simple but effective way to fight climate change. AI Helps Protect Ancient Buildings In Dunhuang, AI technology is being used to protect the Mogao Grottoes, a world cultural heritage site. The AI system monitors the temperature, humidity and carbon dioxide levels inside the caves. It can predict when the environment might harm the ancient paintings and send warnings to the staff. Also, AI helps repair damaged parts of the paintings by analyzing thousands of similar images. This technology allows us to protect cultural treasures for future generations. 51．Where can we probably read these pieces of news? A．In a storybook. B．In a science magazine. C．In a travel guide. 52．What is special about the smart water-saving system? A．It reuses washing machine water for flushing toilets. B．It can make water clean for drinking. C．It needs no electricity to work. 53．Why do cities build green roofs? A．To make the city look more beautiful. B．To provide space for people to grow vegetables. C． To reduce building temperature and absorb rainwater. 54．How does AI help protect the Mogao Grottoes? A．By replacing the staff to clean the caves. B．By monitoring the environment and predicting harm. C．By stopping tourists from entering the caves. 55．What do the three news items have in common? A．They all introduce ways to save water. B．They show how technology helps solve real-world problems. C．They are all about environmental protection. C The ancient town of Wuzhen in Zhejiang Province is famous for its water scenery and traditional architecture. Every year, it attracts millions of visitors from all over the world. But Wuzhen is not just a museum of the past; it is also a town of the future. In 2014, Wuzhen became the permanent host of the World Internet Conference. Since then, the town has been equipped with the latest technology, including 5G networks, facial recognition payment, and smart garbage bins. Visitors can pay for their meals with a smile, and the bins can sort waste automatically. However, the most impressive thing is how technology and tradition are mixed. The old stone bridges and wooden houses remain unchanged, but inside, you can find high-tech companies and creative studios. Young people who love both culture and technology come here to start their businesses. They create digital art, develop cultural apps, and design smart products that carry traditional elements. The success of Wuzhen shows that tradition and modernity can live together in harmony. The local government believes that protecting the old and welcoming the new is the key to sustainable development. They have set up a fund to support young innovators and help them turn their ideas into reality. Today, Wuzhen is a model of "smart tourism". It uses big data to manage visitor flow and improve service. During peak seasons, the system suggests less crowded routes to tourists, making the experience more enjoyable. The town also has a digital museum where visitors can learn about its history through virtual reality. As one visitor said, "Walking in Wuzhen is like traveling through time. You can feel the past, but you can also see the future." 56．What is Wuzhen famous for? A．Its high-tech companies. B．Its water scenery and traditional architecture. C．The World Internet Conference only. 57．What can visitors do in Wuzhen according to the passage? A．Pay for meals with facial recognition. B．Drive smart cars on the old stone bridges. C．Attend a traditional painting class for free. 58．What does the underlined word "mixed" in Paragraph 3 probably mean? A．Separated. B．Compared. C．Combined . 59．What is the key to Wuzhen's sustainable development according to the local government? A．Building more high-tech companies. B．Protecting the old and welcoming the new. C．Attracting more foreign visitors. 60．Which of the following shows the structure of the passage? (①=Paragraph 1, etc.) A．①/②③④/⑤⑥ B．①②③/④⑤/⑥ C．①/②③/④⑤⑥ B卷（计50分） 一、选词填空。 请从方框中选择适当的词并用其正确形式填空，使文章完整连贯。注意每空一词，每词仅用一次，有两词为多余项。（共10题；每小题1分，计10分） country attract rapid easy since communicate they develop environment protect one with In recent years, China's space industry has ________ (61) quickly.

For years, the villagers thought it was useless because it had no strong current. But a group of college students saw its potential. They designed a special low-speed water turbine (涡轮) that can generate electricity even with a slow flow. The turbine was installed last year. It now provides enough power for the whole village, lighting up 50 houses and powering a small water pump for irrigation. The villagers no longer have to rely on expensive diesel generators (柴油发电机). The project has changed the village. Children can study at night, and the villagers can watch TV to learn about the outside world. The college students said, "We wanted to use our knowledge to help rural areas. This slow river is like a gift from nature." The local government plans to build more such turbines in other villages with similar rivers. This green energy solution is not only cheap but also environmentally friendly. It shows that with creativity, even a "lazy river" can make a big difference. Mind map: The "Lazy River" Project Location: A small village in 76______ Problem: The river flowed too 77______ to be used traditionally.

These beautiful birds are among the rarest in the world. They almost disappeared in the 1980s because of wetland loss and hunting. To save the cranes, the Chinese government set up the Zhalong Nature Reserve in 1987. It is now one of the most important wetlands for birds in Asia. The reserve covers over 2,100 square kilometers and provides a safe home for many species. Workers in the reserve work hard to protect the cranes. They patrol (巡逻) the wetland every day to stop illegal hunting. They also plant reeds (芦苇) to improve the birds' habitat. In winter, when the water freezes, they put food on the ice for the cranes that stay behind. Thanks to these efforts, the number of red-crowned cranes in Zhalong has increased from about 100 in the 1980s to over 300 today. The reserve has also become a popular place for bird lovers and researchers. However, the workers know that the protection must continue. Climate change and human activities still threaten the wetland. "We must keep this paradise for the cranes," said one worker. "They are not just birds; they are a symbol of peace and good luck in our culture." 81．When did the Chinese government set up the Zhalong Nature Reserve? ________________________________________________________________________ 82．Why did the red-crowned cranes almost disappear in the 1980s? ________________________________________________________________________ 83．What do workers do in winter to help the cranes? ________________________________________________________________________ 84．How many red-crowned cranes are there in Zhalong now? ________________________________________________________________________ 85．What can we do to protect wetlands like Zhalong?

First, ideas can change the world. For example, the idea of the Internet was once just a dream, but now it has connected the whole world and changed our daily lives. Many great inventions, such as the light bulb and the airplane, were all born from simple but creative ideas. How can we get good ideas? I think we should observe life carefully and ask questions about everything around us. Collaboration with others is also important because different minds can inspire each other. Besides, reading widely can open our eyes and help us think in new ways. As middle school students, we can develop creative thinking by being curious and not being afraid of making mistakes. We should take part in science activities and share our ideas with teachers and classmates. Let’s turn our ideas into reality and make the world a better place. 1 学科网（北京）股份有限公司 $
