Before paper, people wrote on bamboo（竹子）or silk（丝绸）. Bamboo was heavy, and so silk was expensive. So people needed a better way to write and keep records. In the Eastern Han Dynasty, a man named Cai Lun   14  up with a new idea. He used tree bark（树皮）, old cloth, and fishing nets to make paper. This new kind of paper was much   15  to make and use. It   16  "Cai Lun paper" and was loved by people. Later on, the art of papermaking   17  to Korea and Japan, and then to the Arab world. From there, it finally reached Europe. The spread of papermaking greatly   18  up cultural communication（文化交流）. People could share knowledge more easily than before. Today, paper   19  in many different ways — from books and newspapers to paper cups and bags. It   20    one of the most important inventions in human history. Next time you use a piece of paper, think about the long journey it has travelled through time. 13. A. invents B. invented C. is invented D. was invented 14.

B 阅读下列短文，根据短文内容，从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。 The Wheel: An Invention That Changed the World What do you think is the most important invention of all time? For many people, the answer is the wheel. It is believed to be one of the oldest inventions in human history. Historians believe that the wheel was first used around 3500 BC in ancient Mesopotamia（美索不达米亚）. At first, it was not used for transportation（交通）. Instead, it was used by potters（陶工）to make clay pots. The potter's wheel allowed them to create round and balanced pots much more easily than before. It took about 300 years for people to realize that the wheel could also be used for moving things. The first wheeled vehicles（车辆）were probably simple carts pulled by animals. This changed the world completely. Goods（货物）could be transported over long distances. Trade developed between different places, and civilizations（文明）could share their cultures. Today, the wheel is everywhere — in cars, bikes, trains, and machines. It has become such a common part of our lives that we hardly think about it. But without the wheel, the modern world as we know it would be impossible. 24. What was the wheel first used for? A. Transportation. B. Making clay pots. C. Building houses. D. Pulling carts with animals 25. How did the wheel change the world? A. It helped people make clothes more easily. B. It made it possible to transport goods over long distances. C. It was used to create the first television. D. It helped people learn to read and write. 26. What can we learn from the last paragraph? A. The wheel is no longer useful today. B. The wheel is everywhere but we often don't notice it. C. The wheel is only used in cars and bikes. D. People are trying to invent something to replace the wheel. C 阅读下列短文，根据短文内容，从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。 Turning Ideas into Reality with 3D Printers Have you ever imagined turning your ideas into real objects with the press of a button? With 3D printers, this is now possible. A 3D printer is a machine that can create three-dimensional（三维的）objects from a digital file（数字文件）. The object is first designed on a computer. Then the file is sent to the printer, which builds the object layer by layer（逐层地）using materials（材料）like plastic（塑料）. What can 3D printers make? Almost anything! Toys, chairs, tables, and even parts of houses can all be made by 3D printers. In medicine, 3D printers are used to make artificial（人造的）body parts. In the food industry, they can even print chocolate and other foods! Scientists believe that in the future, 3D printers will be used to build houses on other planets（星球）. Perhaps the most exciting thing about 3D printers is that they allow anyone to become an inventor. You don't need a big factory — just an idea and a 3D printer. As one expert（专家）said, "3D printing is not just about making things. It is about turning creative ideas into reality." 27. How does a 3D printer create an object? A. It cuts materials with a sharp knife. B. It builds the object layer by layer from a digital file. C. It mixes different liquids together. D. It shapes materials by hand. 28. Which of the following is NOT mentioned as something 3D printers can make? A. Toys. B. Chairs. C. Airplanes. D. Artificial body parts. 29. What makes 3D printers special according to the passage? A. They are very cheap to buy. B. They can only be used in big factories. C. They allow anyone to become an inventor. D. They were invented thousands of years ago. D 阅读下列短文，根据短文内容，从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。 Smart Inventions That Protect Animals When we think about great inventions, we often think of things like phones, computers, or high-speed trains. But some of the most creative inventions are designed not for people, but for animals. One great example is the animal bridge. In many countries, highways cut through forests and mountains where wild animals live. Every year, thousands of animals are killed when they try to cross these roads. To solve this problem, animal bridges were built. These bridges are covered with grass and trees to make them look like a natural part of the forest. Animals can cross the road safely without ever seeing a car. Another smart invention is the fish ladder（鱼梯）. When dams（水坝）are built across rivers, fish can no longer swim upstream to lay their eggs（产卵）. A fish ladder is like a set of steps that allows fish to swim around the dam. Water flows down each step, and fish can jump from one step to the next until they reach the other side. These inventions show that creative ideas can solve all kinds of problems — even problems that are not our own. They remind us that being creative is not just about making human life better. It is also about protecting the world we share with other living things（生物）. So next time you learn about a great invention, ask yourself: who is it really helping? 30. Why were animal bridges built? A. To help wild animals cross roads safely. B. To make highways look more beautiful. C. To give drivers a place to rest. D. To connect different cities. 31. How does a fish ladder help fish? A. It carries fish in a special vehicle. B. It allows fish to swim around dams step by step. C. It moves the dam to a different place. D. It teaches fish a new way to lay eggs. 32. What does the word "they" in Paragraph 4 refer to? A. The wild animals. B. The dams. C. The fish ladders. D. The animal bridges and fish ladders. 33. What is the main message of the passage? A. Inventions should only be made for people. B. Creative ideas can help both humans and animals. C. Animal bridges are more important than phones. D. Fish ladders are the most useful invention. 第二部分　非选择题（共20分） 四、阅读与表达。(本大题共4小题；第34-36题每题2分，第37题4分，共10分) The First Radio Message Across the Atlantic On 12 December 1901, something amazing happened. A radio message was sent across the Atlantic Ocean for the first time in history. The man behind this great achievement（成就）was an Italian inventor named Guglielmo Marconi. At that time, many scientists believed that radio waves（无线电波）could only travel in straight lines. Because the Earth is round, they thought it was impossible to send a message across the ocean. But Marconi believed it could be done. He spent years developing his idea and trying out（测试）different equipment（设备）. On that historic day, Marconi was on a hill in Newfoundland, Canada. He flew a kite with an antenna（天线）attached to it — the antenna was needed to receive the signal. Suddenly, through his earphones（耳机）, he heard three short sounds: dot-dot-dot（滴滴滴）. It was the letter "S" in Morse code（莫尔斯电码）, sent from a station in England, over 3,000 kilometres away! Marconi's success changed the world. It proved that wireless communication（无线通信）across long distances was possible. People could now share information across oceans without wires or cables（线缆）. This invention later led to the development of radio, television, and even the mobile phones we use today. Marconi's story teaches us an important lesson: when you believe in your idea, don't let other people's doubts（怀疑）stop you. Keep trying, and your ideas may one day change the world — just as Marconi's did. 34. Who sent the first radio message across the Atlantic Ocean? ________________________________________________________________________________________ 35. What did many scientists believe was impossible before Marconi's success? ________________________________________________________________________________________ 36. How far was the radio message sent — from England to Canada? ________________________________________________________________________________________ 37. Marconi's story teaches us to believe in our ideas even when others doubt them. Do you agree with this lesson? Why or why not? Please give at least 2 reasons and you can share your own experience. ________________________________________________________________________________________ ________________________________________________________________________________________ 五、书面表达。(本大题共1小题，共10分) 38. 从下面两个题目中任选一题，根据中文和英文提示，完成一篇不少于60词的英语短文。文中已给出的内容不计入总词数。提示词语仅供选用。请不要写出真实的校名、姓名和地名。 题目① 学校英语俱乐部正在举办"The Invention That Changed My Life"主题演讲活动。请用英语写一篇短文，介绍一项对你的生活产生重要影响的发明。 提示词语：invent, change, convenient（方便的）, connect, use...for... 内容提示： · What is the invention? · How has it changed your life? · Why do you think it is important? ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ ____________________________________________________________________________________________ 题目② 假设你是李华，你的英国笔友Mark来信说他正在做一个关于"世界伟大发明"的项目，想了解中国的发明。请你用英语写一封回信，介绍一下中国的造纸术或你感兴趣的一项发明。 提示词语：invent, ancient China, spread, be used for, change the world 内容提示： · What invention would you like to introduce? · Who invented it and when? · Why is it important?

First, many great inventions were doubted at first. For example, when I wanted to join the school science competition, my classmates said my project was too simple. But I kept working and finally won third prize. Second, if Marconi had given up because of others' doubts, we might not have mobile phones today. I learned that believing in yourself is the first step to turning ideas into reality. 38. 例文（题目①）： The mobile phone is the invention that has changed my life the most. Before I had a mobile phone, it was difficult for me to contact（联系）my parents when I was at school. Now, I can call them whenever I need. My mobile phone is also used for learning — I use it to look up new words and listen to English recordings. It is like a small computer in my pocket. I believe that mobile phones have made our lives more convenient and connected. Without them, the modern world would be very different. 例文（题目②）： Dear Mark, I'm happy to hear about your project on great inventions. I'd like to introduce papermaking to you. Papermaking was improved by Cai Lun in ancient China around 105 AD. Before paper was invented, people wrote on bamboo or silk. Bamboo was heavy and silk was expensive. Cai Lun used tree bark, old cloth, and fishing nets to make paper. This made writing much cheaper and easier. Later on, the art of papermaking spread to Korea, Japan, and then to the Arab world and Europe. It greatly speeded up cultural communication（文化交流）across the world. I think paper is one of the greatest Chinese inventions because it helped knowledge reach every corner of the world. I hope this helps with your project! Let me know if you want to learn more.

A radio message was sent across the Atlantic Ocean for the first time in history. The man behind this great achievement（成就）was an Italian inventor named Guglielmo Marconi. At that time, many scientists believed that radio waves（无线电波）could only travel in straight lines. Because the Earth is round, they thought it was impossible to send a message across the ocean. But Marconi believed it could be done. He spent years developing his idea and trying out（测试）different equipment（设备）. On that historic day, Marconi was on a hill in Newfoundland, Canada. He flew a kite with an antenna（天线）attached to it — the antenna was needed to receive the signal. Suddenly, through his earphones（耳机）, he heard three short sounds: dot-dot-dot（滴滴滴）. It was the letter "S" in Morse code（莫尔斯电码）, sent from a station in England, over 3,000 kilometres away! Marconi's success changed the world. It proved that wireless communication（无线通信）across long distances was possible. People could now share information across oceans without wires or cables（线缆）. This invention later led to the development of radio, television, and even the mobile phones we use today. Marconi's story teaches us an important lesson: when you believe in your idea, don't let other people's doubts（怀疑）stop you. Keep trying, and your ideas may one day change the world — just as Marconi's did. 34.

For many people, the answer is the wheel. It is believed to be one of the oldest inventions in human history. Historians believe that the wheel was first used around 3500 BC in ancient Mesopotamia（美索不达米亚）. At first, it was not used for transportation（交通）. Instead, it was used by potters（陶工）to make clay pots. The potter's wheel allowed them to create round and balanced pots much more easily than before. It took about 300 years for people to realize that the wheel could also be used for moving things. The first wheeled vehicles（车辆）were probably simple carts pulled by animals. This changed the world completely. Goods（货物）could be transported over long distances. Trade developed between different places, and civilizations（文明）could share their cultures. Today, the wheel is everywhere — in cars, bikes, trains, and machines. It has become such a common part of our lives that we hardly think about it. But without the wheel, the modern world as we know it would be impossible. 24. What was the wheel first used for? A. Transportation. B. Making clay pots. C. Building houses. D. Pulling carts with animals 25. How did the wheel change the world? A. It helped people make clothes more easily. B. It made it possible to transport goods over long distances. C. It was used to create the first television. D. It helped people learn to read and write. 26. What can we learn from the last paragraph? A. The wheel is no longer useful today. B. The wheel is everywhere but we often don't notice it. C. The wheel is only used in cars and bikes. D. People are trying to invent something to replace the wheel. 【答案】24．B 25．B 26．B 【导语】说明文。介绍轮子的发明史——最初用于制陶，后才用于交通，最终彻底改变了世界。与教材"What do you think is the most useful invention?"呼应。 24．细节理解。第二段"it was used by potters to make clay pots"表明轮子最初用于制陶。A项是后来的用途。故选B。 25．细节理解。第三段"Goods could be transported over long distances."说明轮子使长途运输货物成为可能。A/C/D未提及。故选B。 26．主旨推断。末段"we hardly think about it"表明轮子无处不在但人们很少注意到它。A、C、D三项与原文矛盾。故选B。 C 阅读下列短文，根据短文内容，从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。 Turning Ideas into Reality with 3D Printers Have you ever imagined turning your ideas into real objects with the press of a button? With 3D printers, this is now possible. A 3D printer is a machine that can create three-dimensional（三维的）objects from a digital file（数字文件）. The object is first designed on a computer. Then the file is sent to the printer, which builds the object layer by layer（逐层地）using materials（材料）like plastic（塑料）. What can 3D printers make? Almost anything! Toys, chairs, tables, and even parts of houses can all be made by 3D printers. In medicine, 3D printers are used to make artificial（人造的）body parts. In the food industry, they can even print chocolate and other foods! Scientists believe that in the future, 3D printers will be used to build houses on other planets（星球）. Perhaps the most exciting thing about 3D printers is that they allow anyone to become an inventor. You don't need a big factory — just an idea and a 3D printer. As one expert（专家）said, "3D printing is not just about making things. It is about turning creative ideas into reality." 27. How does a 3D printer create an object? A. It cuts materials with a sharp knife. B. It builds the object layer by layer from a digital file. C. It mixes different liquids together. D. It shapes materials by hand. 28. Which of the following is NOT mentioned as something 3D printers can make? A. Toys. B. Chairs. C. Airplanes. D. Artificial body parts. 29. What makes 3D printers special according to the passage? A. They are very cheap to buy. B. They can only be used in big factories. C. They allow anyone to become an inventor. D. They were invented thousands of years ago. 【答案】27．B 28．C 29．C 【导语】说明文。基于教材3D打印话题改编，介绍3D打印机如何将数字设计变为实物，涵盖原理、用途和意义。三道题考查过程理解、信息排除和主旨总结。 27．细节理解。第二段"builds the object layer by layer"是3D打印的核心原理。A/C/D均不是文中描述的工作原理。故选B。 28．信息排除。第三段列举了toys, chairs, tables, houses, artificial body parts, chocolate，飞机(airplanes)未提及。故选C。 29．主旨总结。末段"they allow anyone to become an inventor"和"You don't need a big factory"说明其特别之处。A、B、D三项与原文矛盾。故选C。 D 阅读下列短文，根据短文内容，从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。 Smart Inventions That Protect Animals When we think about great inventions, we often think of things like phones, computers, or high-speed trains. But some of the most creative inventions are designed not for people, but for animals. One great example is the animal bridge. In many countries, highways cut through forests and mountains where wild animals live. Every year, thousands of animals are killed when they try to cross these roads. To solve this problem, animal bridges were built. These bridges are covered with grass and trees to make them look like a natural part of the forest. Animals can cross the road safely without ever seeing a car. Another smart invention is the fish ladder（鱼梯）. When dams（水坝）are built across rivers, fish can no longer swim upstream to lay their eggs（产卵）. A fish ladder is like a set of steps that allows fish to swim around the dam. Water flows down each step, and fish can jump from one step to the next until they reach the other side. These inventions show that creative ideas can solve all kinds of problems — even problems that are not our own. They remind us that being creative is not just about making human life better. It is also about protecting the world we share with other living things（生物）. So next time you learn about a great invention, ask yourself: who is it really helping? 30. Why were animal bridges built? A. To help wild animals cross roads safely. B. To make highways look more beautiful. C. To give drivers a place to rest. D. To connect different cities. 31. How does a fish ladder help fish? A. It carries fish in a special vehicle. B. It allows fish to swim around dams step by step. C. It moves the dam to a different place. D. It teaches fish a new way to lay eggs. 32. What does the word "they" in Paragraph 4 refer to? A. The wild animals. B. The dams. C. The fish ladders. D. The animal bridges and fish ladders. 33. What is the main message of the passage? A. Inventions should only be made for people. B. Creative ideas can help both humans and animals. C. Animal bridges are more important than phones. D. Fish ladders are the most useful invention. 【答案】30．A 31．B 32．D 33．B 【导语】说明文。基于教材动物桥/鱼梯改编，探讨为保护动物而设计的发明——动物桥让动物安全过马路，鱼梯帮助鱼类越过水坝。四道题考查因果推理、原理理解、指代判断和主旨总结。 30．因果推理。第二段"thousands of animals are killed...To solve this problem, animal bridges were built"说明建桥原因。B/C/D非真正原因。故选A。 31．原理理解。第三段"allows fish to swim around the dam...jump from one step to the next"描述鱼梯工作原理。A/C/D与原文不符。故选B。 32．指代判断。第四段"These inventions show..."指代前两段介绍的animal bridges和fish ladders两种发明。A/C项片面，B项错误。故选D。 33．主旨总结。全文强调创新的力量不仅在于让人类生活更好，也在于保护动物——"Creative ideas can solve all kinds of problems"。A、C、D三项均片面或过于绝对。故选B。 第二部分　非选择题（共20分） 四、阅读与表达。(本大题共4小题；第34-36题每题2分，第37题4分，共10分) The First Radio Message Across the Atlantic On 12 December 1901, something amazing happened.
