I’m one of the Unitree G1 humanoid robots. Let me tell you my story, straight from my own metal-and-motor heart. ▲  Since day one, engineers at Unitree dreamed big: robots that could balance, sprint, leap and adapt. They gave me LiDAR, depth cameras and advanced motion control systems, and taught me how to stand firm, walk steadily, and finally dance. Robots like me practised hard before the night of 16 February, when hundreds of millions tuned in to watch the 2026 Spring Festival Gala. Then came the moment. I stepped onto one of the world’s brightest stages, right on cue with my fellow robots. We were there to perform. At one point, I leapt into the air and flipped before landing squarely on my feet. The audience watched in awe before breaking into applause. Some of us even performed moves inspired by kung fu—all while children shared the stage with us. At one dramatic moment, one of us suddenly fell flat on his back. Just as the audience began to wonder what was happening, he rose smoothly to his feet. It turned out to be a trick—a classic drunken boxing move. Last year, robots first appeared at the Spring Festival Gala, twirling handkerchiefs and performing simple movements. We’ve improved a lot since then! Videos of this year’s show have gone viral online. People replay the flips. They slow down the kicks. “It looks like something straight out of a sci-fi film,” one comment reads. At the same time, they ask, “What will robots do next?” That question excites me. Because the gala stage is only the beginning. In the future, robots like me may work in places where people need extra hands, such as care settings and disaster zones. And of course, some of us may remain in entertainment and education—performing, teaching, inspiring curiosity in children who look at us and think, “I want to build something like that one day.” The gala was my debut. The future is my next stage. And I am ready to step forward. 34．Which of the following fits best in the ▲ ? A．I wasn’t built to sit quietly on a shelf. B．I was created in a large factory in China. C．People often believe robots are only cold machines. D．Many robots are built for display rather than action. 35．The drunken boxing move was designed to ________. A．test whether the robot could recover from a fall B．create a surprising moment for the audience C．show the robot’s control over its movements D．introduce the robot’s new performance style 36．How does the writer show the robots’ progress? A．By giving detailed numbers about their training. B．By comparing this year’s show with last year’s. C．By describing their appearance in a scientific way. D．By explaining how engineers improved the robots. 37．What can we infer from the passage? A．Robots will focus mostly on performing and teaching. B．Robots are already widely used in disaster rescue. C．Robots are becoming popular with young people. D．Robots may take on different kinds of social roles. 38．Why does the writer tell the story in the first person? A．To explain technical details more clearly. B．To make the story more personal and lively. C．To show how robots are controlled. D．To present the gala in a relaxed tone. 六、完形填空(共12分) The blue morpho butterfly (蓝闪蝶) is very 39 because its wings can reflect (反射) light and produce a bright blue color.Wang Wanlin and his team at Shenzhen University noticed this wonder of nature and they’ve looked beyond it. The team came up with a possible answer to a modern problem: how to keep our cars cool without 40 a sense of beauty. In answer, the team designed a type of thin film (薄膜). It acts almost like the reflective paints on the market, but there is a key 41 : This one offers many bright colors. The coating (涂层) has three skins. The top skin is made from titanium (钛), silicon (硅) and oxygen. The two below are made from special glass and a thin silver mirror. The glass skin can give the film a look just like the blue butterfly’s wings. When traditional paint takes in light, its temperature rises. That’s why, on a sunny day, the inside of a car can feel like an oven. The team’s idea was to design the film to scatter (分散) light and then cool down the paint. And the team didn’t 42 there. They continued to find out how to control reflection to change the color of the coating. Wang and his team made coating test products in several colors. They put them under the burning sun for seven hours. The researchers kept an eye on their temperatures. They found that all the test products stayed about 2℃ cooler than the air around them. Their cooling ability became much clearer when the researchers tested them directly on a car. A car that used traditional paint reached 75℃. The team’s test products 43 to keep the temperature around 42℃. Wang hopes the new coating will soon be used to cover electric cars. “It could greatly reduce the energy use of electric car air conditioning, and 44 , increase the distance a car can travel.” he says. 39．A．popular B．lively C．large D．unusual 40．A．putting up B．giving up C．taking up D．picking up 41．A．role B．detail C．difference D．effect 42．A．break B．complete C．succeed D．stop 43．A．managed B．happened C．tried D．used 44．A．in return B．as a result C．after all D．in other words 七、任务型阅读(共10分) 请阅读下面语篇，根据其内容回答问题。 Kid Inventors’ Day is celebrated each year on January 17th. It was set up years ago to remember the special achievements of some young people as well as to encourage children to create their own inventions. Do you have imagination? Do you like to solve problems? Can you think outside the box? If so, you could be the next great inventor. You don’t have to be an adult, a scientist, or a genius (天才) to be an inventor. Many inventors got their start when they met a problem and tried to solve it. What you do need is something that kids have plenty of: curiosity (好奇心) and imagination. Some of your ideas may lead to great inventions. In fact, many inventors started creating things when they were young. Even people around us can invent things at a young age. ☆Benjamin Franklin invented the swim fins (脚蹼) when he was only 11. ☆Albert Sadacca invented Christmas lights at the age of 15. ☆Feng Boyao and Meng Shuqi, two students from Taiyuan, made a new kind of Braille (盲文) reader at the age of 14. What should you do if you have a great idea for an invention? Try to create a model of your idea. Once you have a model, you can test it. Sometimes your idea turns out to be not as great as you thought. At other times, though, you realize it is a good idea and your model can help you figure out how to make it even better. Do you dream of creating the world’s next great invention? Why not start trying today? There’s no need to wait! Just put your curiosity and creativity to good use now! 45．When is Kid Inventors’ Day? 46．What qualities do you need to be an inventor? 47．Why does the writer mention some inventions made by the young? 48．What should you do after creating a model of your idea? 49．Can you become an inventor? Why or why not? 八、书面表达(共25分) 50．科学技术日新月异，新发明给人们的生活带来了很多便利。假如你是李华，你们学校英语社团正在开展以“创新生活”为主题的征文活动，请你结合自身经历介绍你日常生活中最喜欢的发明，说说你对它的评价及它对你的生活产生的影响。 要点： 1．What invention do you like best in our daily life? 2．What do you think of it? 3．How does it affect (影响) your life? 注意： 1．短文须包含上述要点，可适当增加细节，以使行文连贯； 2．文中不能出现真实姓名和学校名称； 3．词数80～100。 ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2 / 8 1 / 8 学科网（北京）股份有限公司 $ 2025-2026学年八年级下册英语单元测试 Unit2·提升卷（参考答案） 一、语法选择(共10分) 【答案】 1．C 2．C 3．B 4．A 5．C 6．A 7．B 8．C 9．B 10．A 二、选词填空(共5分) 【答案】11．B 12．C 13．E 14．D 15．A 三、用单词的适当形式填空（共8分） 16．【答案】importance 17．【答案】scientific 18．【答案】success 19．【答案】development 20．【答案】creation 21．【答案】medical 22．【答案】encouraging 23．【答案】treats 四、按要求填写句子，补全对话（每题2分，共10分） 【答案】24．What do you think is the most useful invention 25．No, it wasn’t 26．How long did it take him to invent it 27．I agree with you 28．Why do you think so 五、阅读理解 (共20分) A.

I’m one of the Unitree G1 humanoid robots. Let me tell you my story, straight from my own metal-and-motor heart. ▲  Since day one, engineers at Unitree dreamed big: robots that could balance, sprint, leap and adapt. They gave me LiDAR, depth cameras and advanced motion control systems, and taught me how to stand firm, walk steadily, and finally dance. Robots like me practised hard before the night of 16 February, when hundreds of millions tuned in to watch the 2026 Spring Festival Gala. Then came the moment. I stepped onto one of the world’s brightest stages, right on cue with my fellow robots. We were there to perform. At one point, I leapt into the air and flipped before landing squarely on my feet. The audience watched in awe before breaking into applause. Some of us even performed moves inspired by kung fu—all while children shared the stage with us. At one dramatic moment, one of us suddenly fell flat on his back. Just as the audience began to wonder what was happening, he rose smoothly to his feet. It turned out to be a trick—a classic drunken boxing move. Last year, robots first appeared at the Spring Festival Gala, twirling handkerchiefs and performing simple movements. We’ve improved a lot since then! Videos of this year’s show have gone viral online. People replay the flips. They slow down the kicks. “It looks like something straight out of a sci-fi film,” one comment reads. At the same time, they ask, “What will robots do next?” That question excites me. Because the gala stage is only the beginning. In the future, robots like me may work in places where people need extra hands, such as care settings and disaster zones. And of course, some of us may remain in entertainment and education—performing, teaching, inspiring curiosity in children who look at us and think, “I want to build something like that one day.” The gala was my debut. The future is my next stage. And I am ready to step forward. 34．Which of the following fits best in the ▲ ? A．I wasn’t built to sit quietly on a shelf. B．I was created in a large factory in China. C．People often believe robots are only cold machines. D．Many robots are built for display rather than action. 35．The drunken boxing move was designed to ________. A．test whether the robot could recover from a fall B．create a surprising moment for the audience C．show the robot’s control over its movements D．introduce the robot’s new performance style 36．How does the writer show the robots’ progress? A．By giving detailed numbers about their training. B．By comparing this year’s show with last year’s. C．By describing their appearance in a scientific way. D．By explaining how engineers improved the robots. 37．What can we infer from the passage? A．Robots will focus mostly on performing and teaching. B．Robots are already widely used in disaster rescue. C．Robots are becoming popular with young people. D．Robots may take on different kinds of social roles. 38．Why does the writer tell the story in the first person? A．To explain technical details more clearly. B．To make the story more personal and lively. C．To show how robots are controlled. D．To present the gala in a relaxed tone. 【答案】34．D 35．B 36．B 37．D 38．B 【导语】本文以一名宇树机器人的口吻介绍了宇树所研发的动作机器人的发展历程，文章结尾表达了它们将会在社会的不同方面发挥作用。 34．推理判断题。根据第二段“Since day one, engineers at Unitree dreamed big: robots that could balance, sprint, leap and adapt.”可知，宇树的工程师们有一个制造能够灵活运动的机器人的梦想，D选项“很多机器人是为了展示而非行动而制造的”，正好与后文描述的这款机器人被设计来行动形成鲜明对比，从而突出了它的独特性和工程师的远大目标。故选D。 35．推理判断题。根据第六段“At one dramatic moment, one of us suddenly fell flat on his back. Just as the audience began to wonder what was happening, he rose smoothly to his feet.”可知，醉拳动作的设计意在制造出人意料的惊喜时刻，从而吸引观众的注意。故选B。 36．推理判断题。根据第七段“Last year, robots first appeared at the Spring Festival Gala, twirling handkerchiefs and performing simple movements. We’ve improved a lot since then!”可知，作者是通过和去年的表演相对比，来展现机器人的进步的。故选B。 37．细节理解题。根据倒数第三段“In the future, robots like me may work in places where people need extra hands, such as care settings and disaster zones.”可知，机器人可能会承担各种各样的社会角色。故选D。 38．推理判断题。阅读全文并根据第一段“Let me tell you my story, straight from my own metal-and-motor heart.”可知，本文以第一人称来叙述是为了让故事更个性化、更生动。故选B。 六、完形填空(共12分) The blue morpho butterfly (蓝闪蝶) is very 39 because its wings can reflect (反射) light and produce a bright blue color.Wang Wanlin and his team at Shenzhen University noticed this wonder of nature and they’ve looked beyond it. The team came up with a possible answer to a modern problem: how to keep our cars cool without 40 a sense of beauty. In answer, the team designed a type of thin film (薄膜). It acts almost like the reflective paints on the market, but there is a key 41 : This one offers many bright colors. The coating (涂层) has three skins. The top skin is made from titanium (钛), silicon (硅) and oxygen. The two below are made from special glass and a thin silver mirror. The glass skin can give the film a look just like the blue butterfly’s wings. When traditional paint takes in light, its temperature rises. That’s why, on a sunny day, the inside of a car can feel like an oven. The team’s idea was to design the film to scatter (分散) light and then cool down the paint. And the team didn’t 42 there. They continued to find out how to control reflection to change the color of the coating. Wang and his team made coating test products in several colors. They put them under the burning sun for seven hours. The researchers kept an eye on their temperatures. They found that all the test products stayed about 2℃ cooler than the air around them. Their cooling ability became much clearer when the researchers tested them directly on a car. A car that used traditional paint reached 75℃. The team’s test products 43 to keep the temperature around 42℃. Wang hopes the new coating will soon be used to cover electric cars. “It could greatly reduce the energy use of electric car air conditioning, and 44 , increase the distance a car can travel.” he says. 39．A．popular B．lively C．large D．unusual 40．A．putting up B．giving up C．taking up D．picking up 41．A．role B．detail C．difference D．effect 42．A．break B．complete C．succeed D．stop 43．A．managed B．happened C．tried D．used 44．A．in return B．as a result C．after all D．in other words 【答案】39．D 40．B 41．C 42．D 43．A 44．B 【导语】本文介绍蓝闪蝶翅膀反射光线的特性启发了深圳大学团队研发新型汽车降温薄膜，该技术能降低车内温度并提升电动汽车续航。 39．句意：蓝闪蝶是一种非常不寻常的蝴蝶，因为其翅膀能够反射光线并产生明亮的蓝色。 popular受欢迎的；lively活跃的；large大的；unusual不寻常的。根据“this wonder of nature and they’ve looked beyond it.”可知，这是自然奇观，说明它是不寻常的。故选D。 40．句意：这个团队提出了一种可能解决现代问题的方案：如何在不放弃美感的情况下保持汽车凉爽。 putting up张贴；giving up放弃；taking up占据；picking up挑选。根据“how to keep our cars cool without ... a sense of beauty”可知，是指如何在不放弃美感的情况下保持汽车凉爽。故选B。 41．句意：它几乎类似于市场上的反射性涂料，但有一个关键区别：这种薄膜提供了多种鲜艳的颜色。 role角色；detail细节；difference区别；effect影响。根据“This one offers many bright colors.”可知，这是与传统涂料的区别之处。故选C。 42．句意：团队并没有就此止步。 break打破；complete完成；succeed成功；stop停止。根据“They continued to find out how to control reflection to change the color of the coating.”可知，他们继续探索如何控制反射，说明他们没有停止。故选D。 43．句意：该团队的测试产品成功将温度保持在42℃左右。 managed设法做到；happened发生；tried尝试；used使用。根据前文可知，此处是指团队经过研究，使得其测试产品成功将温度保持在42℃左右，manage to do sth“成功做到某事”。故选A。 44．句意：它可以极大地减少电动汽车空调的能源消耗，从而增加汽车可行驶的里程。 in return作为回报；as a result因此；after all毕竟；in other words换句话说。空后句是前句产生的结果，用as a result表示结果。故选B。 七、任务型阅读(共10分) 请阅读下面语篇，根据其内容回答问题。 Kid Inventors’ Day is celebrated each year on January 17th. It was set up years ago to remember the special achievements of some young people as well as to encourage children to create their own inventions. Do you have imagination? Do you like to solve problems? Can you think outside the box? If so, you could be the next great inventor. You don’t have to be an adult, a scientist, or a genius (天才) to be an inventor. Many inventors got their start when they met a problem and tried to solve it. What you do need is something that kids have plenty of: curiosity (好奇心) and imagination. Some of your ideas may lead to great inventions. In fact, many inventors started creating things when they were young. Even people around us can invent things at a young age. ☆Benjamin Franklin invented the swim fins (脚蹼) when he was only 11. ☆Albert Sadacca invented Christmas lights at the age of 15. ☆Feng Boyao and Meng Shuqi, two students from Taiyuan, made a new kind of Braille (盲文) reader at the age of 14. What should you do if you have a great idea for an invention? Try to create a model of your idea. Once you have a model, you can test it. Sometimes your idea turns out to be not as great as you thought. At other times, though, you realize it is a good idea and your model can help you figure out how to make it even better. Do you dream of creating the world’s next great invention? Why not start trying today? There’s no need to wait! Just put your curiosity and creativity to good use now! 45．When is Kid Inventors’ Day? 46．What qualities do you need to be an inventor? 47．Why does the writer mention some inventions made by the young? 48．What should you do after creating a model of your idea? 49．Can you become an inventor?
