Her grandfather had trouble using his wheelchair because there were stairs at his house. Maya knew that traditional wheelchairs couldn't climb stairs, and she wanted to help her grandfather. She started by studying how wheels work and how stairs are built. She spent many hours in her father's workshop, testing different designs. Her first few attempts failed. The wheelchair was either too heavy or couldn't balance properly. But Maya didn't give up. She read books about robotics and watched videos about engineering. She even asked her science teacher for advice. After two years of hard work, she finally created a wheelchair with special wheels that could lift the chair up one step at a time. Her grandfather was very proud of her. Maya's invention not only helped her grandfather but also inspired other inventors to think about solutions for people with disabilities. ( )1. Why did Maya want to build a new wheelchair? A. She wanted to make money. B. Her grandfather needed one that could climb stairs. C. She was asked by her teacher. D. She wanted to win a science fair.

B 3-D printing is one of the most exciting technologies of the 21st century. It allows us to create three-dimensional objects from a digital file. Unlike traditional manufacturing, which involves cutting or carving materials away, 3-D printing builds objects layer by layer. This makes it possible to create complex shapes that would be very difficult to make with traditional methods. 3-D printing has many applications. In the medical field, it is used to create custom prosthetics, such as artificial arms and legs, that fit the user perfectly. In architecture, it is used to create detailed models of buildings. In education, it helps students bring their designs to life. One of the greatest advantages of 3-D printing is that it can reduce costs. For example, Easton LaChappelle used a 3-D printer to create an artificial arm that cost only $500, compared to $80,000 for a traditional one. 3-D printing is also more sustainable because it produces less waste. As the technology continues to improve, it will likely change many industries and make products more accessible to people around the world. ( )6. What is the main topic of the passage? A. Easton LaChappelle's story. B. The history of manufacturing. C. 3-D printing technology and its uses. D. Medical treatments for disabilities. ( )7. How does 3-D printing work? A. It cuts materials away. B. It builds objects layer by layer. C. It carves objects from wood. D. It melts metal into shapes. ( )8. Which of the following is NOT mentioned as an application of 3-D printing? A. Custom prosthetics. B. Building models. C. Food production. D. Education. ( )9. What is one advantage of 3-D printing mentioned in the passage? A. It is always faster than traditional methods. B. It produces more waste. C. It can reduce costs. D. It requires no digital files. ( )10. How does the passage support the idea that 3-D printing is beneficial? A. By explaining its disadvantages. B. By comparing it to Easton's story. C. By providing examples of its uses. D. By describing its history. C Dear Easton, I am a 14-year-old student who wants to become an inventor. I read your story in a magazine and I was truly inspired. Like you, I have always been curious about how things work. I have already built a simple robot from a kit, but I want to create something that can help others, just like you did. However, I feel a bit lost. I have many ideas, but I don't know where to start. Also, my parents worry that spending too much time on inventions might affect my schoolwork. I don't want to give up my dream, but I also don't want to disappoint my parents. Could you please give me some advice on how to start my journey as an inventor and how to balance it with my studies? Yours sincerely, Tom Dear Tom, It's wonderful that you have such a passion for invention at a young age! Here is my advice: First, start small. You don't need to build a complex machine right away. Begin with simple projects that you can finish. Second, learn from failure. Every failed attempt teaches you something valuable. Third, talk to your parents about your dream. Explain to them why invention matters to you and how it can actually help you learn practical skills. Show them your progress and ask for their support. Remember, I also faced challenges when I was your age. I spent long hours in my room working on my projects, but I also made sure to complete my schoolwork. Finally, never stop being curious and keep asking "how can I make this better?" I believe you have what it takes to be a great inventor. Good luck! Best wishes, Easton LaChappelle ( )11.

His parents worry about his schoolwork. D. He can't find a teacher. ( )14. What is Easton's first piece of advice to Tom? A. Build a complex machine. B. Start small with simple projects. C. Give up on schoolwork. D. Ask for money from others. ( )15. What does Easton suggest Tom should do with his parents? A. Ignore them. B. Talk to them and explain his dream. C. Stop inventing. D. Argue with them. 八、完形填空（阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳答案） At a science fair, Easton LaChappelle, a young inventor, met a girl (1) ______ Jenny. She was born without an arm.

He made them from wood and used them to swim faster. Franklin loved experimenting and never stopped inventing throughout his life. At 15, Louis Braille invented a reading system for blind people. He was inspired by a military code and simplified it into six dots that could be felt with fingers. His system is still used today. In 2012, 13-year-old Jack Andraka invented a test for pancreatic cancer. He read about the disease online and developed a new detection method. His test is 90% accurate and much cheaper than traditional methods. These young inventors show that age doesn't matter when it comes to making a difference. They all shared common qualities: curiosity, persistence, and a desire to help others. They observed problems in the world and worked hard to solve them. Their stories inspire us to believe that anyone can become an inventor.
