The company started its IPO (首次公开募股) process and became one of the most valuable AI companies in the world. DeepSeek's AI model has been used by more people than any other Chinese AI product. DeepSeek was founded in 2023 by a team of young Chinese engineers. Their goal was to build AI that could understand and communicate in Chinese as well as English. Within just three years, DeepSeek has grown rapidly. Its AI assistant app has over 500 million users worldwide. What makes DeepSeek special? First, it is much cheaper to use than many foreign AI products. Second, it works very well with Chinese language tasks, such as writing essays in Chinese and solving maths problems step by step. Third, DeepSeek keeps improving its technology to make its AI smarter. DeepSeek's success shows that Chinese AI technology is becoming stronger. Other Chinese AI companies, like Baidu's ERNIE and Alibaba's Qwen, are also making great progress. Experts say that in the future, China may have the most advanced AI technology in the world. However, some experts are worried. They say that as AI becomes more powerful, we must make sure it is used sensibly and safely. "AI should help people, not replace them," said one expert. 41. What happened to DeepSeek in July 2026? A. It was founded. B. It started its IPO. C. It closed down. D. It moved to another country. 42. How many users does DeepSeek's AI assistant app have? A. Over 50 million. B. Over 500 million. C. Over 5 billion. D. Over 500 thousand. 43. Which is NOT a reason that makes DeepSeek special? A. It is cheaper to use. B. It works well with Chinese. C.

C The Internet has become a necessary part of teenagers' lives. However, staying safe online is just as important as being able to use the Internet. Digital literacy—the ability to use digital technology wisely—is something every student should develop. First, you should protect your personal information. Never share your full name, home address, phone number or school name with strangers online. Some people may use this information to find you in real life, which could be dangerous. Second, learn to evaluate the information you find online. Not everything on the Internet is true. Some websites provide biased or wrong information. Before you believe something, check it on other trustworthy websites. This is an important part of digital literacy. Third, be sensible about the time you spend online. Studies show that teenagers who spend more than three hours a day on screens have a higher risk of eye problems and poor sleep. It is better to take a break every 30 minutes when using digital devices. Fourth, be kind to others online. Cyberbullying (网络欺凌) is a serious problem. If someone sends you mean messages, do not reply. Instead, tell a parent or teacher. Remember that words on a screen can hurt just as much as words spoken face to face. By following these tips, you can enjoy the benefits of the Internet while staying safe. Digital literacy is not just about knowing how to use technology—it is about using it sensibly and responsibly. 46. What is digital literacy according to the passage? A. The ability to code programs. B. The ability to use technology wisely. C. The ability to type fast. D. The ability to build websites. 47. Why should you NOT share personal information online? A. It is not interesting. B. It may be used to find you in real life. C. It is against the law. D. Your parents will be angry. 48. What should you do before believing online information? A. Share it with friends. B. Check it on other trustworthy websites. C. Delete it immediately. D. Reply to the author. 49. How often should you take a break when using digital devices? A. Every 10 minutes. B. Every 20 minutes. C. Every 30 minutes. D. Every 60 minutes. 50. What should you do if someone sends you mean messages online? A. Reply angrily. B. Ignore it completely. C. Tell a parent or teacher. D. Delete your account. 第二节 阅读填空(本大题共5小题，每小题1分，共5分) Smart devices have changed our daily lives in many ways. 51 Smartphones let us communicate with anyone, anywhere. Smartwatches track our heart rate and exercise data. Smart speakers play music and control other devices with just our voice. However, these devices also bring some problems. 52 Some young people spend too much time on their phones and forget to talk to people face to face. 53 To solve this, many families have set up "no-phone" rules during meals. Another concern is privacy (隐私). Smart devices collect a lot of data about us. 54 We should read the privacy policy carefully before using any new device. 55 A. They make our lives more convenient and connected. B. This data may include where you go, what you buy and who you talk to. C. Smart devices are very expensive to buy. D. One big problem is that people depend on them too much. E. This can help us understand how our information is used. F.

My old computer was too slow and could not r 62 smoothly when I opened many apps at the same time. It often crashed when I tried to watch online videos or do research for my school projects. The shop assistant showed me several models and helped me c 63 their features carefully. I wanted a laptop that was light enough to carry to school every day, but also powerful enough to handle all my tasks. The assistant recommended a model with a fast processor, plenty of memory and a long b 64 life. She said it was one of the most popular choices among students this year. After careful evaluation, I decided to buy it. It cost me about five thousand yuan, which was more expensive than my old one, but I think it is worth the price. With this new laptop, I can study more efficiently, complete my homework much faster and enjoy a smoother digital experience. I also use it to connect to the I 65 to search for information, communicate with my classmates online and share my work with my teachers. Having the right digital device really makes a difference in our studies today. 六、语法填空(本大题共10小题，每小题1分，共10分) 阅读短文，在空白处填入一个适当的单词或用括号内所给词的正确形式填空，使短文通顺、连贯。 The computer 66 (invent) in the 1940s.

However, staying safe online is just as important as being able to use the Internet. Digital literacy—the ability to use digital technology wisely—is something every student should develop. First, you should protect your personal information. Never share your full name, home address, phone number or school name with strangers online. Some people may use this information to find you in real life, which could be dangerous. Second, learn to evaluate the information you find online. Not everything on the Internet is true. Some websites provide biased or wrong information. Before you believe something, check it on other trustworthy websites. This is an important part of digital literacy. Third, be sensible about the time you spend online. Studies show that teenagers who spend more than three hours a day on screens have a higher risk of eye problems and poor sleep. It is better to take a break every 30 minutes when using digital devices. Fourth, be kind to others online. Cyberbullying (网络欺凌) is a serious problem. If someone sends you mean messages, do not reply. Instead, tell a parent or teacher. Remember that words on a screen can hurt just as much as words spoken face to face. By following these tips, you can enjoy the benefits of the Internet while staying safe. Digital literacy is not just about knowing how to use technology—it is about using it sensibly and responsibly. 46. What is digital literacy according to the passage? A. The ability to code programs. B. The ability to use technology wisely. C. The ability to type fast. D. The ability to build websites. 【答案】B 【解析】根据第一段"Digital literacy—the ability to use digital technology wisely"，数字素养是明智地使用数字技术的能力。故选B。 47. Why should you NOT share personal information online? A. It is not interesting. B. It may be used to find you in real life. C. It is against the law. D. Your parents will be angry. 【答案】B 【解析】根据第二段"Some people may use this information to find you in real life, which could be dangerous"。故选B。 48. What should you do before believing online information? A. Share it with friends. B. Check it on other trustworthy websites. C. Delete it immediately. D. Reply to the author. 【答案】B 【解析】根据第三段"Before you believe something, check it on other trustworthy websites"。故选B。 49. How often should you take a break when using digital devices? A. Every 10 minutes. B. Every 20 minutes. C. Every 30 minutes. D. Every 60 minutes. 【答案】C 【解析】根据第四段"It is better to take a break every 30 minutes when using digital devices"。故选C。 50. What should you do if someone sends you mean messages online? A. Reply angrily. B. Ignore it completely. C. Tell a parent or teacher. D. Delete your account. 【答案】C 【解析】根据第五段"If someone sends you mean messages, do not reply. Instead, tell a parent or teacher"。故选C。 第二节 阅读填空(本大题共5小题，每小题1分，共5分) Smart devices have changed our daily lives in many ways. 51 Smartphones let us communicate with anyone, anywhere.
