（A）
Huang Xuhua, a famous Chinese submarine (潜艇) designer, is known for his hard work, creativity and love for his country. His journey from a young boy in a small village to a top scientist in China is truly inspiring.
Huang Xuhua was born in a small village in Guangdong Province. When he was very young, China was going through many changes. Huang was always curious about the ocean and how things worked. He loved reading books and trying small experiments. Huang was especially good at math and physics. The two subjects helped him build a strong foundation for his future career. When he grew older, he wanted to learn medicine at first under the influence of his parents who were both doctors in his hometown. However, to save China, Huang got into one of China's best universities to study Naval Architecture. His university life was not easy, but Huang never gave up. He graduated with excellent grades in the end.
After graduation, Huang joined a research institute (机构) and focused on submarine design. There he faced many challenges, but he always kept strong-willed and put his shoulder to the wheel with other workmates. His efforts paid off in the end. China’s first nuclear-powered submarine was independently developed and built without any help of other countries. This project was not only a big step in technology but also the key to guarding China’s safety. Huang and his team worked day and night, even when things seemed impossible. His dream and love for our country kept him going on.
Huang’s work has earned him many awards, including the State Preeminent Science and Technology Award, one of China’s highest honors. Although Huang achieved success, he remains humble (谦虚的). He often tells young people to stay curious, work hard, and never give up.
Huang Xuhua’s story shows us how dreams and resolutions can lead to great achievements. He really sets a good example for all young people.

In the past ten years, great progress has been made in technology. It seems like everything has been reinvented and greatly improved. However, there is one thing that is different. It was invented over 100 years ago but remained (保持) unchanged until now. It is the white cane (盲杖) used by blind people. Many blind people have used this kind of white cane for a long time. However, it has seen no real improvement, until a blind engineer named Kursat decided to make a difference.
Kursat is from Turkey(土耳其). He lost his eyesight at the age of 2. He well understands the difficulties and challenges that the blind face. That’s because he himself is a blind person. As a blind person, when he is at the subway station, he doesn’t know which is his exit (出口). When walking on the street, he may run into obstacles.
Kursat decided to do something to help the blind. He invented a new kind of cane called the WeWalk. This smart cane is equipped (配备) with built — in speakers and different sensors (传感器). The sensors can “see” obstacles in front of it, like a wall or a car, and then the cane will vibrate (震动) to tell the user. It can also connect to the Internet through Bluetooth. It can give the user information about the place he or she is visiting, such as the name of the store or the direction of the library. Besides, the cane can be folded, so it’s easy to carry. What’s more, the price of the WeWalk is around $500, which is relatively cheap compared with other high-tech products for the blind. This invention will bring great changes to the lives of blind people.
In these days, we are talking about flying cars. But blind people are still using just a simple cane. With the WeWalk, blind people can live a more convenient life. It’s really a great invention that shows how technology can help improve people’s lives.
36．What does the word obstacles in the Paragraph 2 mean
A．机会 B．宠物 C．障碍物 D．朋友
37．What can the WeWalk do according to the passage
① It can "see" obstacles and vibrate to tell the user.
② It can connect to the Internet through Bluetooth.
③ It can give the user information about the place.
④ It can help the blind take a plane.
A．①②③④ B．①②③ C．②③④ D．①③④
38．Why did Kursat invent the WeWalk
A．Because he wanted to make money. B．Because he wanted to be famous.
C．Because he wanted to help the blind like him. D．Because he liked inventing things.
39．Which of the following is TRUE according to the passage
A．The WeWalk is very expensive. B．The WeWalk can’t be folded.
C．Kursat lost his eyesight when he was born. D．The WeWalk is a great invention for the blind.
40．Which part of the newspaper can we probably read the passage in
A．Health. B．Science. C．Business. D．Travel.
（C）
On January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeekR1. This smart program can solve math problems, write code, and answer questions like top models such as Open AI’s GPT-40, but it costs much less to build. The team spent only $5.58 million (1/70 of Open AI’s cost) and used 2,048 computer chips (芯片) for two months. This shows that good ideas can beat big money.
DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other Als need lots of prepared examples, but R1 improves by itself. For example, in a global math test, it got 79.8% right, a litter higher than Open AI’s model. A simple version of R1 can even run on low-cost computers, helping schools and small companies.
DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers all over the world started projects to study it. A German scientist said experiments (实验) with RI cost $10 instead of $300 with other Als. Even Meta (a famous U. S. tech company) top scientist said, “This kind of free AI could change the world.”
US tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving (证明) that smart ideas beat expensive tools.
As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money.
41．According to paragraph 1, DeepSeek-R1 is able to ______.
①write code ②work out math problems ③do experiments ④answer questions
A．①②③ B．①③④ C．②③④ D．①②④
42．It cost about ______ to build Open AI.
A．$5.58 million B．$65 billion C．$390 million D．$300
43．The underlined words “it” in paragraph 2 refers to ______.
A．GPT-40 B．Open AI C．Meta D．R1
44．The engineer says, “We want AI to be a friend, not something only rich people can use” to ______.
A．explain why RI is free B．compare R1 with Meta's AI
C．encourage students to study math D．show that expensive AI models are useless
45．The main purpose of the passage is to ______.
A．explain how computer chips work
B．introduce a low-cost AI model from China
C．encourage students to become programmers
D．compare Chinese and American AI technologies
