二、 阅读理解
“Wow！ Look at that！ Isn’t it a real fish？” The bionic（仿生） fish， named “Jinlin”， was swimming lively like a real one. It was developed by researchers at Shanghai Ocean University. This invention isn’t just for fun—it shows how humans copy nature to solve problems. That is a science called bionics.
Over millions of years， animals and plants have developed smart ways to survive. For example， kingfishers are experts at moving fast between air and water with very little noise. Through their study， scientists discovered that the birds’ long beaks（喙） enabled this ability. Then they used the knowledge to change the front of the high-speed train. This change cut down the noise level， increased speed by 10％ and greatly saved energy. This combination（结合） of biology and engineering is the key to success in bionics. And it has set the stage for the rise of other new technologies.
Driven by robotics and AI， bionics has grown rapidly. The AI-powered bionic fish “Jinlin” can be used for environmental protection and deep sea exploration. In medicine， bionic arms can work similarly to real arms. Sensors allow the user to “feel” touch and pressure. Motors help the bionic arms make movements， like human muscles （肌肉）. With AI， the bionic arms are able to “learn” new tasks and become smarter over time. These inventions are examples to show how bionics bridges biology and new technologies to solve humans’ problems.
Although so much progress has been made， bionics faces challenges. Nature’s designs are hard to copy perfectly. As for bionic arms， one key area of development is Brain-Computer Interface（脑机接口）. More work on direct communication between the brain and bionic arms is required to control movements as naturally as real arms. Researchers are also working on creating new materials and structures which can sense and repair themselves.
While there’s still a long way to go， the future of bionics is full of possibilities. Stay hungry. Stay foolish. Maybe you’ll be the next one to change the world！
1. Why does the writer mention “Jinlin” at the beginning of the passage？
A. To suggest some new ideas. B. To lead into the topic of bionics.
C. To explain the habits of fish. D. To show the importance of bionics.
2. What can we learn from Paragraph 3？
A. Robotics and AI have developed fast because of bionics.
B. The bionic fish “Jinlin” is used for medical purposes.
C. Motors allow the bionic arms to make movements.
D. Sensors help bionic arms learn new tasks over time.
3. According to Paragraph 4， how would scientists make bionic arms more like real ones？
① By connecting motors with smartphones. ② By developing new materials and structures.
③ By improving Brain-Computer Interface. ④ By changing the shape and look of bionic arms.
A. ①② B. ②③ C. ①④ D. ③④
4. Which of the following shows the use of bionics？
A. Drawing a picture of birds by watching real birds.
B. Building a house with natural materials like wood.
C. Designing a camera by copying some insects’ eyes.
D. Learning to dance by studying monkeys’ movements.

情境三 3D打印革新实体制造方式，赋能多领域创新，为科技与生活提供全新可能。
三、 任务型阅读
3D printing is a relatively new way to make solid objects. But how does 3D printing work？
All 3D printing starts with computer design. Makers use special software（软件） to create a digital model of what they want to print. The computer program takes the maker’s design and puts it into a language the 3D printer understands. After the maker designs the model， the computer sends the instructions to the 3D printer.
3D printers build objects by pushing out thin layers of material. It’s a bit like toothpaste coming out of a tube. The layers can be plastic， metal and glass. Some printers turn a liquid called resin into a solid.
3D printers in a library or school usually use thin plastic thread（线）. It comes in every colour you can imagine！ People wind the thread around spools（轴） and feed it into the 3D printer. When the print job starts， the printer pulls in the thread and melts it. The melted plastic goes into a printhead and is pushed out one layer at a time， following the maker’s design. Then the plastic becomes hard as it cools.
The design might not be right. Sometimes the printer makes a mistake and pushes out layers in a messy pile makers call “noodles”. When this happens， the maker has to check the design and the printer and try again.
Some scientists hope that one day they’ll be able to 3D print organs such as hearts or lungs to replace damaged ones. What do you think should be 3D printed next？ （素材选自Ask）
