B Wang Yihan, a 15-year-old student from Shanghai, noticed that her grandfather, who had poor eyesight, often struggled to thread a needle (穿针). Seeing his difficulty, she decided to design a tool to help him. In her school's innovation club, Wang learned about 3D printing and basic engineering. She spent weeks researching existing needle threaders on the market. Most of them were either too small for elderly people to hold or broke easily. Wang wanted to create something more user-friendly. She designed a small, brightly coloured plastic device with a large handle for easy gripping. The device has a tiny hook (钩子) that pulls the thread through the needle's eye. Wang used a 3D printer to create several prototypes (原型). After testing and improving her design three times, she finally succeeded. Her grandfather can now thread a needle in seconds. Wang's teacher, Mr. Li, was very proud of her. "This project shows that young people can use technology to solve real-life problems," he said. "It also teaches the importance of patience and empathy." Wang hopes to study engineering in the future and invent more helpful products for the elderly. (　　)59.

D Sitting for too long is harmful to our health. Studies show that office workers spend about 75% of their working hours seated. To solve this problem, a British designer, John Smith, invented a standing desk that encourages users to change their posture regularly. The desk is different from traditional standing desks. It has a special sensor (传感器) that reminds users to sit or stand every 30 minutes. When it is time to change, the desk makes a soft sound and the surface moves up or down slowly. This design prevents users from staying in one position for too long. Although it is not as comfortable as a normal desk at first, many users say it helps them feel more energetic. "I used to feel tired and sleepy in the afternoon," said one user. "Now I feel much better." The desk also has a built-in exercise bike, so users can do light exercise while working. In conclusion, this innovative desk is a good solution to the problem of sitting too much. It makes people more aware of their health and encourages an active lifestyle. (　　)65. Why did John Smith invent the special desk? A. To help people sit comfortably for long hours. B. To encourage users to change postures regularly. C. To replace all traditional desks in the office. D.
