This AI can solve (解决) math problems, write code and answer questions. It’s like Open AI’s GPT-4, but it costs much less to make. The team spent only $5.58 million (1/70 of Open AI’s cost) and used 2,048 computer chips (芯片) in two months. This shows good ideas can win over a lot of money. DeepSeek-R1 learns by trying many times. Other AIs need lots of prepared examples, but R1 improves by itself. In a global math test, it got 79.8% right, a little higher than Open AI’s model. A simple version (版本) of DeepSeek-R1 can run on low-cost computers, helping schools and small companies. DeepSeek-RI is free to use and change. On its first day online, over 19,000 programmers (程序员) around the world started to study it. A German scientist said doing tests with R1 only cost $10, while it cost $300 with other AIs. A top scientist from Meta (a famous U. S. tech company) said this free AI could change the world. U. S. tech companies are worried. Meta plans to spend more money on AI research. Experts (专家) say China is keeping up quickly. A report in Nature magazine said R1 makes great progress. It shows smart ideas are better than expensive tools. As a DeepSeck engineer said, “We want AI to be a friend for everyone, not just for rich people.” With R1, China shows the world that great things come from new ideas and hard work, not just money. 31．What does “improves by itself” mean in the article? A．It needs programmers to fix mistakes. B．It becomes better through practice. C．It copies answers from other AIs. D．It only works with expensive tools. 32．Which of the following descriptions about the simple version of R1 is not right? A．It can solve math problems. B．It works on low-cost computers. C．It helps schools and small companies. D．It costs $10 to use. 33．Why did Meta plan to spend more money on AI research? A．Because they wanted to help Chinese companies. B．Because they needed to build more computer chips. C．Because they were worried about DecpSeek-R1. D．Because they wanted to hire (雇佣) German scientists. 34．According to the passage, the writer thinks ________ is the most important for success. A．Having enough money. B．New ideas and hard work. C．Using the latest computer chips. D．Copying other countries’ ideas. 35．What is the main purpose (目的) of the article? A．To compare Chinese and American AI technologies. B．To introduce a low-cost AI model from China. C．To explain how computer chips work. D．To encourage students to become programmers. C If you’re a kid who likes to have fun and chat with friends online, here’s some advice on how you can stay safe and avoid problems when necessary. ★Visit safer websites. Your parents and teachers can guide you to the best websites. Some websites have age restrictions, so you might be tempted to lie about your age. It’s safer to tell the truth and avoid those websites until you’re older enough. ★Guard your passwords always. You can set your own passwords. Passwords are your secret. It’s dangerous to tell your passwords to others. So, don’t share your passwords with anyone except your parents. ★Limit what you share with others. Never tell a stranger where you live or your phone number. If you’re not sure whether you should share something, ask a parent. Remember that anything you put online is there forever, even if you try to delete it. If you don’t want your class to know or see something, you shouldn’t share it with anyone online, not even your best friends. ★Be choosy about your online friends. Some websites let kids make lots of unknown friends with people they don’t know. But online friends are not the same as real in-person friends. Never agree to meet an online friend in person or give out personal information. It’s dangerous because some people pretend to be kids online but actually are adults. 36．Which suggestion is about passwords? A．The first one. B．The second one. C．The third one. D．The fourth one. 37．The underlined word “choosy” probably means “________” in Chinese. A．挑剔的 B．宽松的 C．认真的 D．严厉的 38．Which of the following is TRUE according to the passage? A．There aren’t any websites which have age limits. B．You should never tell your family members about your passwords. C．You can never tell strangers about your personal information. D．Online friends are the same as real in-person friends. 39．The purpose of the passage is to ________. A．encourage students to use the Internet B．teach students how to make more friends online C．ask students to set safe passwords online D．tell students how to stay safe online 40．The best title of the passage is “________”. A．Online Safety B．Safe Websites C．Password Safety D．Online Friends 四、 阅读还原（共5小题，每小题1分，满分5分） 请阅读下面的短文，并从下列的六个句子中选择五个还原到原文中，使原文的意思完整、连贯。 Have you ever seen a solar panel (电池板) in your neighborhood? Solar panels take energy from the sun and turn it into electricity. In many parts of the world, solar energy is now the cheapest form of electricity. More and more people have started using solar energy to power(给……供电) their homes. 41 They stop working at night and on rainy days. Is it possible to make them produce electricity all the time? Scientists at Suzhou University, China, have invented a new solar panel now. 42 When a raindrop falls on the solar panel and then roll (滚动) down, it creates fiction (摩擦力) on the surface of the panel. This can then be turned into electricity. Sun Baoquan is one of the inventors. “ 43 ” he says. “It can even provide electricity at night if there is rain.” The solar panel, however, does not make much electricity from falling rain. So Sun Baoquan is still working hard to improve it. He says, “ 44 ” The field of solar energy is developing fast. Scientists around the world have been improving solar panels. 45 Some have been trying to use sunlight to produce liquid and gas fuel(燃料). A．Our new invention can produce electricity in any weather during the day. B．Some have been working on ways to join solar panels and wind power together. C．It can produce electricity not only from solar energy but also from falling rain. D．However, solar panels also have their problems. E．But solar panels help people in many ways. F．With more effort, solar power will become the main source of electricity for ordinary people. 五、 阅读匹配（共5小题，每小题1分，满分5分） 下面的材料A—F介绍了六项发明，请根据Tommy、Mina、Joy、Alan和Diana对某些发明项目的疑惑，帮助他们选出相匹配的选项。 46 The Internet and the World Wide Web have changed our life and even the world.

And who developed the first high-speed printer? ——Mina 48 Jeans are popular among people of all ages. How did they become what they are today? ——Joy 49 I’m interested in Maths. I think zero is a really interesting invention. Where was it invented? ——Alan 50 I learned from a book that Humphry Davy made the first electric light. But the inventor should be Thomas Edison. Is this true? ——Diana A．The first jeans were produced in the 1800s, but weren’t called jeans at that time. As bard-wearing trousers for workers, they were first made of the special cloth used for making tents. Later people made the cloth comfortable and created many different jeans styles. B．The Internet was invented and developed by the US government in the 1960s. At that time, only simple texts could be sent by using the Internet. In 1991, a British scientist invented the World Wide Web that allows people to send texts, photos and videos. C． Chester Carlson invented a dry printing process in 1938. It was the foundation (基础) technology for laser printers to come. In 1953, the first high-speed printer was developed by Remington-Rand. D．Zero was invented in India. On the walls of a temple in India, you can find the oldest known form of “0”. The Indian mathematicians were the first to treat zero as a number. E. Printing was invented and developed in China during the Sui and Tang Dynasties. Later the improvement of printing made it possible to produce books more quickly and cheaply. F. The first electric light was made in 1800 by Humphry Davy. But Thomas Edison finally produced a light bulb that could glow (发光) for over 1,500 hours. 六、语法填空（共10小题，每小题1分，满分10分） There is a 15-year-old boy named Attar.

The team spent only $5.58 million (1/70 of Open AI’s cost) and used 2,048 computer chips (芯片) in two months. This shows good ideas can win over a lot of money. DeepSeek-R1 learns by trying many times. Other AIs need lots of prepared examples, but R1 improves by itself. In a global math test, it got 79.8% right, a little higher than Open AI’s model. A simple version (版本) of DeepSeek-R1 can run on low-cost computers, helping schools and small companies. DeepSeek-RI is free to use and change. On its first day online, over 19,000 programmers (程序员) around the world started to study it. A German scientist said doing tests with R1 only cost $10, while it cost $300 with other AIs. A top scientist from Meta (a famous U. S. tech company) said this free AI could change the world. U. S. tech companies are worried. Meta plans to spend more money on AI research. Experts (专家) say China is keeping up quickly. A report in Nature magazine said R1 makes great progress. It shows smart ideas are better than expensive tools. As a DeepSeck engineer said, “We want AI to be a friend for everyone, not just for rich people.” With R1, China shows the world that great things come from new ideas and hard work, not just money. 31．What does “improves by itself” mean in the article? A．It needs programmers to fix mistakes. B．It becomes better through practice. C．It copies answers from other AIs. D．It only works with expensive tools. 32．Which of the following descriptions about the simple version of R1 is not right? A．It can solve math problems. B．It works on low-cost computers. C．It helps schools and small companies. D．It costs $10 to use. 33．Why did Meta plan to spend more money on AI research? A．Because they wanted to help Chinese companies. B．Because they needed to build more computer chips. C．Because they were worried about DecpSeek-R1. D．Because they wanted to hire (雇佣) German scientists. 34．According to the passage, the writer thinks ________ is the most important for success. A．Having enough money. B．New ideas and hard work. C．Using the latest computer chips. D．Copying other countries’ ideas. 35．What is the main purpose (目的) of the article? A．To compare Chinese and American AI technologies.

Your parents and teachers can guide you to the best websites. Some websites have age restrictions, so you might be tempted to lie about your age. It’s safer to tell the truth and avoid those websites until you’re older enough. ★Guard your passwords always. You can set your own passwords. Passwords are your secret. It’s dangerous to tell your passwords to others. So, don’t share your passwords with anyone except your parents. ★Limit what you share with others. Never tell a stranger where you live or your phone number. If you’re not sure whether you should share something, ask a parent. Remember that anything you put online is there forever, even if you try to delete it. If you don’t want your class to know or see something, you shouldn’t share it with anyone online, not even your best friends. ★Be choosy about your online friends. Some websites let kids make lots of unknown friends with people they don’t know. But online friends are not the same as real in-person friends. Never agree to meet an online friend in person or give out personal information. It’s dangerous because some people pretend to be kids online but actually are adults. 36．Which suggestion is about passwords? A．The first one. B．The second one. C．The third one.
