Here are some of the most influential inventions and the stories behind them. The Printing Press (印刷机) In the 15th century, books were rare and expensive because they had to be copied by hand. Johannes Gutenberg came up with a brilliant idea—a machine that could print books quickly and cheaply. His printing press made it possible to produce books in large numbers. As a result, knowledge spread more widely, and more people learned to read and write. The Light Bulb Before the light bulb, people used candles and oil lamps for light. Thomas Edison didn’t invent the first light bulb, but he created a practical and long-lasting one. He tested thousands of materials before finding the right one for the filament. His invention changed the world by bringing light to homes and streets, extending the hours people could work and play. The Internet Perhaps the most powerful idea of modern times is the Internet. It started as a small network for scientists to share information. Over time, it grew into a global system that connects billions of people. The Internet has changed how we communicate, learn, work, and even think. It shows that a small idea can grow into something huge when the right people work on it. What do these inventions have in common? All of them started with a simple question: “Is there a better way?” They were driven by curiosity and the desire to solve problems. They also required years of hard work and many failures along the way. As Edison once said, “Genius is one percent inspiration and ninety-nine percent perspiration.” ( ) 26. What made books expensive before the printing press was invented? A. They were made of expensive materials.　　　B. They had to be copied by hand. C. Only rich people could read them.　　　D. There were not enough writers. ( ) 27. What did Thomas Edison do for the light bulb? A. He invented the first light bulb.　　　B. He created a practical and long-lasting light bulb. C. He used candles and oil lamps for light.　　　D. He tested only one material for the filament. ( ) 28. According to the passage, what common question drove these inventions? A. “How can I become famous?”　　　B. “Is there a better way?” C. “How much money can I make?”　　　D. “Who can help me?” ( ) 29. Which of the following is NOT mentioned as a result of the Internet? A. It connects billions of people.　　　B. It changed how we communicate and work. C. It made books cheaper to produce.　　　D. It changed how we learn and think. ( ) 30. What does the passage mainly tell us? A. The most important inventions in history.　　　B. Great ideas come from hard work and curiosity. C. How to become a famous inventor.　　　D. The differences between old and new inventions. B 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳答案。 The Power of a Simple Idea In a small workshop in Anxi, a young man named Lin Wei was watching his grandmother make tea. She picked the leaves by hand, dried them in the sun, and rolled them carefully. The process had remained almost unchanged for centuries. Lin Wei wondered: Could technology make this better? That question led to four years of hard work. Lin Wei studied how tea leaves change at different temperatures and humidity levels. He designed a machine that could control these conditions precisely. With this machine, tea makers can now produce tea of more consistent quality, regardless of the weather. But Lin Wei didn’t stop there. He realized that many traditional crafts face the same challenge—they rely too much on the skill of individual workers. So he started a workshop where young people can learn traditional skills while also using modern tools. “The idea is not to replace tradition with technology,” he explains, “but to use technology to preserve and improve it.” His story shows that great ideas don’t always have to be completely new. Sometimes, the best ideas are about connecting old traditions with new possibilities. This is especially true in China, where thousands of years of history meet the rapid development of modern technology. As Lin Wei says, “The past gives us roots. The future gives us wings. The power of ideas is in knowing how to grow both.” ( ) 31. What did Lin Wei notice about tea-making in Anxi? A. The process had remained almost unchanged for centuries. B. The tea leaves were not picked by hand anymore. C. The tea was not popular with young people. D. The process was too simple. ( ) 32. What did Lin Wei design to improve tea-making? A. A new type of tea leaf.　　　B. A machine to control temperature and humidity. C. A faster way to pick tea leaves.　　　D. A machine to dry tea leaves in the sun. ( ) 33. What does Lin Wei believe about technology and tradition? A. Technology should replace tradition completely. B. Tradition is more important than technology. C. Technology can be used to preserve and improve tradition. D. Tradition and technology cannot work together. ( ) 34. What does the underlined sentence “The past gives us roots. The future gives us wings.” mean? A. We should forget the past and only look forward. B. We should value both our traditions and new ideas. C. We should choose between tradition and technology. D. We should only focus on the future. ( ) 35. What is the main idea of this passage? A. Traditional crafts are disappearing.　　　B. Technology is always better than tradition. C. Great ideas can come from connecting old and new.　　　D. Tea-making is the most important traditional craft. C 阅读短文，根据内容判断句子正误，正确的填“T”，错误的填“F”。 Have you ever used a 3D printer? This amazing invention can create objects by adding layers of material. The idea started in the 1980s, but it has become much more affordable and widely used in recent years. 3D printing is different from traditional manufacturing. Instead of cutting away material from a larger piece, it builds objects from the bottom up, layer by layer. This is why it’s also called “additive manufacturing” (增材制造). The power of this idea lies in its versatility. In medicine, doctors use 3D printers to make custom implants (植入物) and even human organs. In construction, builders are experimenting with printing houses. In education, students can print models of historical artifacts or science experiments. One of the most exciting areas is the use of recycled materials. Some companies have developed 3D printers that use recycled plastic. This turns waste into useful products and helps protect the environment. However, 3D printing also brings challenges. The cost of industrial 3D printers is still high. The speed is slower than mass production. And there are concerns about people using 3D printers to make weapons or counterfeit (仿冒的) products. As with any new technology, we need to think about how to use it responsibly. The 3D printer shows that a simple idea—adding rather than subtracting—can open up a world of possibilities. What other simple ideas might change our future? ( ) 36. 3D printing is also called “additive manufacturing.” ( ) 37. 3D printing has become less affordable in recent years. ( ) 38. Some companies use recycled plastic in 3D printing to help protect the environment. ( ) 39. The passage says there are no challenges with 3D printing. ( ) 40. The passage mainly discusses how 3D printers are used in medicine only. 四、口语应用（共5小题，每小题2分，共10分） 阅读下面对话，从方框内7个选项中选择5个恰当的句子完成对话。 A: Hi, Li Ming! Have you visited the art and science fair in our city?

But how does a thought in someone’s mind become a product that changes the world? The journey from idea to invention involves several important steps. The first step is identifying a problem or need. Most successful inventions solve a real problem. For example, the telephone was invented because people needed to communicate over long distances. The light bulb was invented because people wanted to see in the dark. Without a clear purpose, even the most creative idea may go nowhere. The second step is research and development. This is where the hard work happens. Inventors study existing solutions and think about how to improve them. They draw plans, build models, and test their designs. Thomas Edison tested over 6,000 materials before finding the right one for the light bulb filament. This stage often involves many failures, but each failure teaches something valuable. The third step is making a prototype (原型). A prototype is a working model of the invention. It doesn’t have to be perfect, but it should show that the idea works. The Wright brothers built many gliders before they succeeded with their first airplane. Each prototype brought them closer to their goal. The fourth step is getting feedback (反馈). Inventors show their prototypes to other people and listen to their suggestions. This helps them find problems they might have missed and improve their designs. Sometimes, other people’s ideas can make an invention even better. The final step is production and sharing. When the invention is ready, it needs to be produced and shared with the world. Some inventions are made in factories and sold in stores. Others are shared online for free. Either way, an invention can only change the world if people know about it and can use it. Today, China is known for its innovative products in many fields. From high-speed trains to mobile payment systems, Chinese inventors are turning ideas into reality. The key to success, as many inventors say, is not just having a good idea—it’s having the courage to keep going when things get difficult. 46.

What makes some ideas special? The answer lies in how they are developed and shared. History shows that great ideas often start with a simple question: “Is there a better way?” When people ask this question, they open their minds to new possibilities. However, having a question is just the beginning. The real work begins when people try to answer it. The journey from idea to reality is rarely easy. Most inventors experience failure many times before they succeed. As Thomas Edison famously said, “I have not failed. I’ve just found 10,000 ways that won’t work.” This shows that persistence (坚持) is just as important as creativity. Every failure teaches something new and brings the inventor one step closer to success. Another key factor is collaboration (合作). Many of the greatest inventions were not made by one person alone. They were the result of people working together, sharing ideas, and building on each other’s work. The Internet, for example, was developed over many years by thousands of scientists and engineers around the world. Finally, a great idea needs to be shared. If no one knows about it, it cannot make a difference. That’s why inventors and creators often spend as much time promoting their ideas as they do developing them. In the end, the power of ideas comes not just from thinking, but from doing. Great ideas are those that are turned into action and shared with the world. 概要部分： Not all ideas change the world.

Here are my thoughts on this topic. First, history has shown us that ideas can truly change the world. For example, the printing press made books available to everyone, and the Internet connects billions of people today. These inventions all started with simple questions like “Is there a better way?” Second, great ideas don’t come by accident. They require us to observe life carefully and ask questions about what we see. When we wonder why things are the way they are, we open our minds to new possibilities. Collaboration is also important because sharing ideas with others can make them even better. As middle school students, we can develop creative thinking in several ways. First, we should never stop asking questions and stay curious about the world. Second, we should be brave enough to try new things and learn from our failures. After all, every failure teaches us something valuable. In conclusion, ideas have the power to shape our future. Let’s keep thinking, keep asking, and keep creating! 学科网（北京）股份有限公司 $
