It is 1 for them to play, to listen to music, and to 2 in touch with their friends. 3 the help of technology, there seems to be nothing that children can’t do now. Technology also helps 4 to know more about their children. For example, if a child is given a mobile phone with a tracking (追踪) device, his parents can find out 5 he is going with the help of the mobile phone. However, there are also some bad 6 of technology. For example, it has become easier for bad people to get in touch with children with the help of technology. They can find personal information about children through special ways on the 7 . So it is very important for parents to 8 their children to keep personal information safe while surfing the internet. Besides this, there is another bad thing about technology. Children now 9 less time doing exercise than before. They are too 10 playing online games. They can even play computer games all day long. If you don’t push them out of the door, they won’t volunteer to go out and play. This is not good for their health.

New wide roads, rich farmland and digital life appear in villages. All these new changes greatly improve villagers’ lives in poor areas. Transport makes traveling much easier than years ago. We have highways, long railways and convenient transport. They connect small villages with big cities. Information and farm products travel much faster now. Farmers can send their crops (庄稼) and vegetables to the whole country with ease. Environmental improvement fights natural disasters. People plant trees on sandy (沙质的) ground to stop sandstorms (沙尘暴). The poor soil becomes good enough for farmland. More farmland brings more chances for local farmers. Villagers no longer worry about farmland shortage (短缺). Digital life comes to the countryside. E-payment and online business change traditional shopping ways. People can sell their local products to customers around the world. More young managers come back to start their own business in their hometowns. Fast business development also brings some serious pollution. Modern development brings environmental problems. We should protect our soil and natural environment while creating social wonders. 根据材料内容选择最佳答案。 11．What connects small villages with big cities? A．Digital life and online business.

But now, scientists are raising them on saline-alkali land (盐碱地) in Bayannuur, Inner Mongolia. Saline-alkali land, known as “cancer of the earth”, is found in places that see little rain. As water evaporates (蒸发), salts from underground come up and make a white crust (硬层) covering the ground. Over time, the soil hardens, which makes it difficult for plants to get water and air. Rice and beans can lose up to 70 percent of what is grown, according to the Food and Agriculture Organization. While bad for plants, salts can be good for crabs. Since late March, scientists at a crab farm in Bayannuur have been caring for 3 million baby crabs, making full use of the city’s salty land and the water from the Yellow River that passes by. To help baby crabs live, scientists have to make sure everything is just right. “Crabs are highly sensitive to changes in water quality, salt levels and temperature,” said scientist Yang Yanping in a talk with the government. With the help of technology, Yang and other scientists have been adding oxygen to the water and keeping an eye on the water temperature. Growing water plants is also important. “They help clean the water, serve as food for crabs and provide hiding places,” Yang told China Daily. “Crabs on the farm will grow faster than usual. The big harvest will come in September, about 20 days earlier than crabs from southern China,” expert Gao Huijun told China Daily. 16．How many baby crabs are scientists raising in Bayannuur?

A．Saline-alkali Land: Bad for All Living Things. B．The Differences Between Northern and Southern Crabs. C．How Water Plants Help Clean River Water. D．New Way: Raising Crabs on Saline-alkali Land. C China is facing an AI-powered transformation. Picture this: The classroom blackboard is replaced with a big screen and students click on tablets to answer questions instead of writing with pencils. AI makes it a reality, offering learning pathways for Chinese students and-bridging the urban-rural digital divide. At a middle school in Guiyang, Guizhou province, English teacher Zeng Xing can use the big screen to show the detailed answers of each student. By analyzing results with AI and big data, the system enables Zeng to meet the specific need of each student. “We can now quickly identify students’ weaknesses and make teaching plans accordingly, which is far more efficient than before,” she says. The smart classroom system also enables students to improve their speaking skills through personalized, interactive dialogues sourced from different English movies, news and poetry. AI can evaluate students’ pronunciation and provide feedback, helping them speak more accurately and with greater confidence. “AI has created opportunities for basic education in remote (偏远的) areas like Guizhou,” says Huang Hui, head of Zeng’s middle school. “AI-powered tools play an important role in bridging urban-rural education gaps by expanding teaching resources and improving accessibility,” Huang adds. Wang Lei, professor at Beijing Normal University’s School of Government revealed that China will release a white paper on AI education in 2025 to help students with enhanced skills for the digital and AI era. In the future, primary and secondary schools in Beijing will offer at least eight class hours of AI courses per academic year to innovative talent. Despite AI’s advantages, it raises concerns about data security and privacy. “It is crucial to establish policies on AI usage, enhance technological oversight, and strengthen ethics (伦理的) education for teachers and students,” says Tang Liang, deputy director of the information center at the Beijing Academy of Educational Sciences. 21．What does AI help Zeng Xing do in her teaching? A．Replace traditional textbooks with tablets. B．Analyze student performance and design targeted plans. C．Reduce the number of exams students take. D．Allow students to learn without teachers. 22．How does AI support students’ speaking skills? A．By letting students watch more English movies. B．By providing real-time feedback on pronunciation. C．By removing the need for speaking practice. D．By translating Chinese into English automatically. 23．What is Huang Hui’s main point about AI in education? A．It is only effective in developed cities. B．It makes classrooms less interactive. C．It increases the cost of education. D．It helps provide equal resources to remote areas. 24．What future plan is mentioned for AI education in China? A．Publishing a white paper on AI education in 2025. B．Training all teachers to become AI experts by 2025. C．Removing traditional subjects from the curriculum. D．Requiring students to use AI tools for all homework. 25．What is a major concern about using AI in education? A．Students might lose interest in learning. B．Data security and privacy could be at risk. C．Teachers may refuse to adopt new technology. D．AI tools are too difficult for students to use. D Do you often forget to sort your rubbish? A Chinese company has created a smart bin that can solve this problem. Using AI and sensors (传感器), it can recognize (识别) different types of waste and sort the waste by itself. This great invention promises a cleaner future where recycling becomes much easier for everyone. The bin looks like an ordinary one, but inside it has a smart “brain”. When you throw in a piece of waste, the built-in camera takes a photo. Within 0.5 seconds, the AI system knows what it is—plastic, paper, glass, or food waste. Then, a robotic (机械的) arm puts it into the right area. The whole process is silent and fast. This Chinese invention is not alone in smart waste management. A foreign company has made a similar bin that can only recognize whether it is full. However, while that one just sends a message, the Chinese bin goes a step further by actually sorting the waste for you. It was not easy to improve the accuracy. Early models often mistook a juice box for paper or failed to tell dirty plastic bags. After thousands of tests and improvements, the company added AI to a large waste database (数据库). Now, the system can make the right choice over 92% of the time in most conditions. According to the United Nations, people produce over 2 billion tons of rubbish around the world each year. Much of it ends up in landfills (垃圾填埋场) or oceans because people don’t sort it properly. This new smart bin provides a simple and effective way to encourage recycling and protect our environment. With such technology, we can turn waste into treasure more easily than ever before. 根据材料内容选择最佳答案，并将其标号填入题前括号内。 26．What does the smart bin of the Chinese company use to tell different types of waste? A．AI and sensors. B．A phone and an app. C．A database and a screen. D．A robotic arm and a camera. 27．What does Paragraph 2 mainly talk about? A．How the smart bin works. B．What the smart bin looks like. C．Why people like the smart bin. D．Where we can use the smart bin. 28．What is the main difference between the Chinese smart bin and the foreign company’s bin? A．The Chinese bin can sort waste by itself. B．The foreign bin is cheaper and easier to use. C．The foreign bin can sort waste more quickly. D．The Chinese bin can tell whether the bin is full. 29．What does the underlined word “accuracy” probably mean in the text? A．How fast it works. B．How correctly it sorts. C．How many kinds it can sort. D．How much waste it can hold. 30．Which of the following is the writer’s OPINION toward the bin? A．The bin’s AI system has a large waste database. B．The AI system can tell the waste in 0.5 seconds. C．This great invention will make recycling much easier. D．The Chinese company should keep improving the smart bin.

In 51 , 13 different intangible cultural heritage (非物质文化遗产) (ICH) skills were used. “Every 52 of this dress tells a story from the past,” Li said. As a “Sichuan ICH Ambassador”, Li’s performance taught young people about traditional arts. After the show, many viewers wanted to learn about these skills online. “I 53 knew bamboo weaving could be so interesting!” wrote a teenage fan on social media. Li Ziqi proved that old traditions can live in 54 times. Her performance reminded everyone: cultural heritage is not 55 history—it is a treasure for the future. 五、任务型阅读（10分） Chinese science scored big again! Du Mengran, a geoscientist (地质学家), and Liang Wenfeng, the founder (创立者) of DeepSeek, have been successfully chosen for Nature in 2025. Together with eight other great people from around the world, they won the honour because they have made many excellent achievements that have pushed for the development of global science this year. Du was chosen for her excellent achievements in exploring the deep-sea world. In the submersible (潜水器) Fendouzhe, her team dived down to over nine kilometers more than 20 times. In the dark deep-sea environment, the team discovered the deepest-known animal ecosystem (生态系统) which is completely new to science on Earth for the first time. When facing the unknown, the best way to do is to go and see for yourself, she says. Her words have become an encouraging motto for many researchers. Liang was chosen for developing new AI models. His company, DeepSeek, released (发布) its powerful and affordable AI model early this year. As soon as the model was released, it shocked the global technology community as it’s equal to the best US model including ChatGPT. It showed that the United States was not as far ahead in the AI field as many people had ever thought. “Nature’s 10” is a yearly list of ten people who made huge contributions to science. It’s not a prize or ranking (排名) but a selection of important stories in science over the past year. It allows others to see these great people who are working hard to help us understand the world.

But now, scientists are raising them on saline-alkali land (盐碱地) in Bayannuur, Inner Mongolia. Saline-alkali land, known as “cancer of the earth”, is found in places that see little rain. As water evaporates (蒸发), salts from underground come up and make a white crust (硬层) covering the ground. Over time, the soil hardens, which makes it difficult for plants to get water and air. Rice and beans can lose up to 70 percent of what is grown, according to the Food and Agriculture Organization. While bad for plants, salts can be good for crabs. Since late March, scientists at a crab farm in Bayannuur have been caring for 3 million baby crabs, making full use of the city’s salty land and the water from the Yellow River that passes by. To help baby crabs live, scientists have to make sure everything is just right. “Crabs are highly sensitive to changes in water quality, salt levels and temperature,” said scientist Yang Yanping in a talk with the government.

The big harvest will come in September, about 20 days earlier than crabs from southern China,” expert Gao Huijun told China Daily. 16．How many baby crabs are scientists raising in Bayannuur? A．7 million. B．3 million. C．20 million. D．70 million. 17．What does the underlined word “They” in Paragraph 5 refer to? A．Baby crabs. B．Scientists. C．Water plants. D．Yellow River water. 18．What does the phrase “cancer of the earth” in Paragraph 2 mean? A．Land that is harmful to plants. B．Land full of wild animals. C．Land perfect for growing rice. D．Land with lots of clean fresh water. 19．The writer writes Paragraph 2 mainly to ________. A．show how to grow crabs on saline land B．introduce different kinds of farm plants C．tell readers the history of Bayannuur D．explain the disadvantages of saline-alkali land 20．Which is the best title for the whole passage? A．Saline-alkali Land: Bad for All Living Things. B．The Differences Between Northern and Southern Crabs. C．How Water Plants Help Clean River Water. D．New Way: Raising Crabs on Saline-alkali Land. 【答案】16．B 17．C 18．A 19．D 20．D 【导语】本文介绍了科学家在内蒙古巴彦淖尔利用盐碱地与黄河水资源养殖螃蟹的创新举措，讲解了盐碱地的特点、养蟹的技术措施以及该养殖模式的生长优势，展现了对盐碱地的创新利用思路。 【详解】16．细节理解题。根据文章第3段“scientists at a crab farm in Bayannuur have been caring for 3 million baby crabs”可知，科学家在巴彦淖尔的蟹场养殖的幼蟹数量为300万只。 17．词句猜测题。根据文章第5段“Growing water plants is also important. ‘They help clean the water, serve as food for crabs and provide hiding places’”可知，划线词前一句点明种植水草十分重要，后文描述的净化水质、作为螃蟹的食物、提供躲避场所都是水草的作用，因此They指代水草。 18．词句猜测题。根据文章第2段“Saline-alkali land, known as ‘cancer of the earth’, is found in places that see little rain... Over time, the soil hardens, which makes it difficult for plants to get water and air. Rice and beans can lose up to 70 percent of what is grown”可知，盐碱地会使土壤硬化，让植物难以获取水分和空气，还会导致农作物大幅减产，对植物有极大危害，因此“cancer of the earth”指的是对植物有害的土地。 19．推理判断题。根据文章第2段内容，该段介绍了盐碱地的分布区域、形成过程，以及其对植物生长、农作物产量的负面影响，核心是阐释盐碱地的劣势，因此作者写第二段的主要目的是解释盐碱地的缺点。 20．最佳标题题。全文围绕“在盐碱地养殖螃蟹”这一创新方式展开，依次介绍了盐碱地的特点、养蟹的条件、技术措施与生长优势，核心是利用盐碱地养蟹的新方法，因此最适合作为全文标题的是“New Way: Raising Crabs on Saline-alkali Land”。 C China is facing an AI-powered transformation.

AI can evaluate students’ pronunciation and provide feedback, helping them speak more accurately and with greater confidence. “AI has created opportunities for basic education in remote (偏远的) areas like Guizhou,” says Huang Hui, head of Zeng’s middle school. “AI-powered tools play an important role in bridging urban-rural education gaps by expanding teaching resources and improving accessibility,” Huang adds. Wang Lei, professor at Beijing Normal University’s School of Government revealed that China will release a white paper on AI education in 2025 to help students with enhanced skills for the digital and AI era. In the future, primary and secondary schools in Beijing will offer at least eight class hours of AI courses per academic year to innovative talent. Despite AI’s advantages, it raises concerns about data security and privacy. “It is crucial to establish policies on AI usage, enhance technological oversight, and strengthen ethics (伦理的) education for teachers and students,” says Tang Liang, deputy director of the information center at the Beijing Academy of Educational Sciences. 21．What does AI help Zeng Xing do in her teaching?

A Chinese company has created a smart bin that can solve this problem. Using AI and sensors (传感器), it can recognize (识别) different types of waste and sort the waste by itself. This great invention promises a cleaner future where recycling becomes much easier for everyone. The bin looks like an ordinary one, but inside it has a smart “brain”. When you throw in a piece of waste, the built-in camera takes a photo. Within 0.5 seconds, the AI system knows what it is—plastic, paper, glass, or food waste. Then, a robotic (机械的) arm puts it into the right area. The whole process is silent and fast. This Chinese invention is not alone in smart waste management. A foreign company has made a similar bin that can only recognize whether it is full. However, while that one just sends a message, the Chinese bin goes a step further by actually sorting the waste for you. It was not easy to improve the accuracy. Early models often mistook a juice box for paper or failed to tell dirty plastic bags. After thousands of tests and improvements, the company added AI to a large waste database (数据库). Now, the system can make the right choice over 92% of the time in most conditions. According to the United Nations, people produce over 2 billion tons of rubbish around the world each year. Much of it ends up in landfills (垃圾填埋场) or oceans because people don’t sort it properly. This new smart bin provides a simple and effective way to encourage recycling and protect our environment. With such technology, we can turn waste into treasure more easily than ever before. 根据材料内容选择最佳答案，并将其标号填入题前括号内。 26．What does the smart bin of the Chinese company use to tell different types of waste? A．AI and sensors. B．A phone and an app. C．A database and a screen. D．A robotic arm and a camera. 27．What does Paragraph 2 mainly talk about? A．How the smart bin works. B．What the smart bin looks like. C．Why people like the smart bin. D．Where we can use the smart bin. 28．What is the main difference between the Chinese smart bin and the foreign company’s bin? A．The Chinese bin can sort waste by itself. B．The foreign bin is cheaper and easier to use. C．The foreign bin can sort waste more quickly. D．The Chinese bin can tell whether the bin is full. 29．What does the underlined word “accuracy” probably mean in the text? A．How fast it works. B．How correctly it sorts. C．How many kinds it can sort. D．How much waste it can hold. 30．Which of the following is the writer’s OPINION toward the bin? A．The bin’s AI system has a large waste database. B．The AI system can tell the waste in 0.5 seconds. C．This great invention will make recycling much easier. D．The Chinese company should keep improving the smart bin. 【答案】26．A 27．A 28．A 29．B 30．C 【导语】本文介绍了一款中国公司发明的智能垃圾桶，阐述其利用AI和传感器自动分类垃圾的工作原理、与国外产品的区别、技术准确性的提升以及对环保的积极意义。 【详解】26．细节理解题。根据第一段“Using AI and sensors (传感器), it can recognize (识别) different types of waste...”可推知，这款智能垃圾桶使用人工智能和传感器来识别不同类型的废物。 27．主旨大意题。第二段描述了“When you throw in a piece of waste, the built-in camera takes a photo...
