“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 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!

1.1． 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.

解析：选B。B 推理判断题。题目询问作者在文章开头提及 “金鳞” 仿生鱼的原因。根据原文第一段 “The bionic (仿生) fish, named ‘Jinlin’... This invention isn’t just for fun—it shows how humans copy nature to solve problems. That is a science called bionics”（这条名为 “金鳞” 的仿生鱼…… 这项发明不只是为了好玩 —— 它向我们展示了人类如何模仿自然来解决问题。这门科学被称为仿生学）可知，作者通过 “金鳞” 仿生鱼这一具体例子，自然地引出 “仿生学” 这一核心话题。选项 A “提出新想法” 原文未提及；选项 C “解释鱼的习性” 与原文内容无关，原文重点是仿生鱼而非真鱼习性；选项 D “体现仿生学的重要性”，开头仅引入话题，未强调重要性；选项 B “引入仿生学话题” 与原文逻辑一致，故答案为 B。

2.2．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.

解析：选C。C 细节理解题。题目询问从第三段可得知的信息。根据原文第三段：选项 A “机器人技术和人工智能因仿生学而快速发展”，与原文 “Driven by robotics and AI, bionics has grown rapidly”（在机器人技术和人工智能的推动下，仿生学发展迅速）表述相反，排除；选项 B“‘金鳞’仿生鱼用于医疗”，原文明确提到 “the AI-powered bionic fish ‘Jinlin’ can be used for environmental protection and deep sea exploration”（“金鳞” 仿生鱼用于环境保护和深海探测），与医疗无关，排除；选项 C “马达帮助仿生手臂做出动作”，与原文 “Motors help the bionic arms make movements, like human muscles”（马达则帮助仿生手臂做出动作，就像人类的肌肉一样）完全一致，正确；选项 D “传感器帮助仿生手臂学习新任务”，原文提到 “With AI, the bionic arms are able to ‘learn’ new tasks”（借助人工智能，仿生手臂能 “学习” 新任务），学习新任务的是人工智能而非传感器，排除。故答案为 C。

3.3． According to Paragraph 4, how would scientists make bionic arms more like real ones? ① By connecting motors with smart phones. 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

解析：选B。B 细节理解题。题目询问根据第四段，科学家如何让仿生手臂更接近真手臂。根据原文第四段 “As for bionic arms, one key area of development is Brain-Computer Interface (脑机接口)... Researchers are also working on creating new materials and structures which can sense and repair themselves”（以仿生手臂为例，脑机接口是其重要的发展方向之一…… 研究人员也在努力研发能够自我感知和自我修复的新型材料与结构）可知，对应的方式是 “改进脑机接口” 和 “研发新型材料与结构”，即②③。选项①“将马达与智能手机连接”、④“改变仿生手臂的形状和外观” 在原文中均未提及，排除。故答案为 B。

4.4． 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.

解析：选C。C 推理判断题。题目询问哪项体现了仿生学的应用，仿生学核心是 “模仿自然（生物特性）解决问题”。选项 A “观察真鸟画鸟”，仅为艺术创作，未利用生物特性解决问题，排除；选项 B “用木材等天然材料建房”，仅使用天然材料，未模仿生物的生存或结构特点，排除；选项 C “模仿某些昆虫的眼睛设计相机”，符合 “模仿生物特性（昆虫眼睛）制造工具（相机）”，属于仿生学应用，正确；选项 D “学习猴子动作跳舞”，仅为动作模仿，无技术或工程应用，排除。故答案为 C。
