Advanced self-driving vehicles, which are powered by clean energy, will significantly reduce traffic accidents and carbon emissions. Moreover, integrated AI systems will manage traffic flow efficiently, saving people’s time and energy. Despite these advantages, challenges will remain. The high cost of developing and maintaining such advanced systems may slow down their global adoption, potentially creating gaps between regions. Furthermore, the rise of automation, while boosting efficiency, could impact employment in traditional transport sectors. Overall, by addressing these challenges through innovation and cooperation, the future transport can pave the way for a greener and more connected world. 第二节 （满分25分） 67．     After a moment of panic, Sheldon’s scientific mind took over. Noticing the low fence beside the steps, he quickly calculated the distance and the required throwing angle. He rolled the newspaper into a tight tube. With a precise underhand throw, he sent the paper sliding smoothly along the fence. It traveled in a perfect bend around the sleeping dog and came to rest right at the front door. A small smile appeared on his face as he continued his route, the crisis expertly solved through physics.     Weeks later, “The Money Project” finally paid off. Sheldon placed his carefully saved money on the counter, receiving the long-wanted scientific tool. His mother’s eyes met his, shining with pride. As he held the tool, happiness filled him — not just for having it, but for earning it. This experience brought him a greater prize: strong belief in his own mind and the knowledge that some fortunes are earned not with money, but with effort and intellect. This was the real treasure, one that would only grow with time. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司2 / 2 学科网（北京）股份有限公司 $ 2025-2026学年高二英语选择性必修第三册单元自测（湖南专用） Unit 2·培优卷 学校:___________班级：___________姓名：___________分数：___________ （时间：120分钟，满分：150分） 注意事项： 1. 答卷前，考生务必将自己的姓名、准考证号填写在答题卡上。 2. 回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上，写在本试卷上无效。 3. 考试结束后，将本试卷和答题卡一并交回。 第一部分 听力(共两节，满分30分) 做题时，先将答案标在试卷上。录音内容结束后，你将有两分钟的时间将试卷上的答案转涂到答题卡上。 第一节(共5小题;每小题1.5分，满分1.5分) 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话读两遍。 1．When did Philo Farnsworth develop his original idea of sending pictures through the air?

Born in the United States to Nigerian parents, Jessica grew up experiencing two different cultures. This unique background inspired her to think about global challenges in new ways. At just 19 years old, while studying mechanical engineering (机械工程) in college, Jessica and her classmates brainstormed a groundbreaking idea: a soccer ball that could produce electricity. The idea for this invention came during a family trip to the countryside of Nigeria, where she saw firsthand how families struggled without regular electricity. The Soccket Ball, a name combining “soccer” and “socket”, looks like any other soccer ball, but it has a special feature. As you play with it, the ball captures the energy from being kicked and rolled. After a game, this energy can power small devices like LED lights. For many families without regular electricity, this invention can make a big difference. Despite gaining strong support from global organizations and media attention, the product faced unexpected difficulties after its launch. Many users reported that the balls broke or stopped working within a few months, failing to live up to the promised three years of use life. The problems led to criticism from users and negative headlines, putting pressure on Uncharted Play, the company Jessica founded. The team openly admitted that they hadn’t expected the equipment to be so damaged by rough play in the country and promised to revise the design with stronger materials and improved internal parts. Despite these setbacks, Jessica and her team at Uncharted Play continued to work on energy solutions. Their latest invention, a portable jump rope that generates electricity, builds on the Soccket’s success with a more durable, lightweight design. Designed for both children and adults, the jump rope can power small devices like phones or flashlights, expanding the reach of their mission. Jessica’s key goal remains unchanged: to provide clean, renewable energy to people around the world, where electricity shortage limits education, health, and economic opportunities. Her journey proves that even simple, fun activities — like playing soccer or jumping rope — can be transformed into powerful tools to address pressing global affairs. 24．What inspired Jessica to invent the Soccket Ball? A．The energy shortage problem she noticed. B．Her mechanical engineering studies. C．Her unique cross-cultural background. D．Her trip to America with her family. 25．Why did the Soccket Ball disappoint users? A．It performed with high costs. B．It was uncomfortable to play with. C．It can only power small devices. D．It didn’t last as long as expected. 26．What does the underlined word “setbacks” in paragraph 4 mean? A．Challenges. B．Improvements. C．Failures. D．Disadvantages. 27．Which of the following words can best describe Jessica? A．Creative and polite. B．Gifted and selfless. C．Outgoing and careful. D．Ambitious and responsible. C A wildfire spreads rapidly through dry bushes and grass toward a group of nearby homes in the hills surrounding a Los Angeles suburb. The plants and decorative landscaping around the first house quickly catch fire, but the house itself remains unharmed, holding firm against the flames. Any small sparks that flicker up along its walls die out almost immediately. What’s surprising is that there are no firefighters or fire extinguishers in sight—yet the house stays safe. The secret is that the flames are being put out by sound waves. This kind of fire control using sound, called acoustic fire suppression, may soon become an important tool in fighting wildfires. To understand how this technology works, we first need to know the basic requirements for a fire to burn. For a fire to keep burning, it needs three key things: heat, fuel, and oxygen. If any one of these is taken away, the fire will stop. Sound waves put out fires by pushing oxygen molecules(分子) away from the fuel, making it impossible for the fire to get the air it needs to keep burning. Jeff Bruder, an engineer who once did energy research at NASA, co-founded a company called Sonic Fire Tech to develop a machine that uses this principle. Bruder explains that the machine makes oxygen move so fast that the fire can’t use it, which stops the burning process effectively. The company has already shown that their device can put out fires from as far as 25 feet away. Using sound to fight fires isn’t a new idea—American research groups and universities have been studying this method for more than ten years. However, Albert Simioni, an expert in fire safety, notes that the main difficulty is making this technology work on a larger scale without producing harmful noise. Sonic Fire Tech has solved this problem by using low-frequency sound waves. While earlier research used sound waves between 30 and 60 hertz (赫兹), Sonic’s device uses waves that are 20 hertz or lower. These low-frequency waves can’t be heard by humans and can travel much farther than higher-pitched sound waves. This technology is especially useful because many homes catch fire during wildfires when small burning pieces of wood (called “embers”） blow into attic vents (阁楼通风口). Sonic’s system uses an electric motor to drive a moving component that creates the sound waves. These waves then travel through metal pipes installed on the roof and under the edges of the house, reaching the vents to stop embers from starting fires inside. 28．What can we infer from the first paragraph about the unharmed house? A．It was built with special fire-resistant materials. B．It was protected by an unusual fire-fighting method. C．The wildfire was too weak to damage it. D．All flammable things were removed in advance. 29．What is the basic working principle of acoustic fire suppression? A．It cuts off the fire’s oxygen supply. B．It reduces the temperature around the fire. C．It prevents the fire from moving fast. D．It creates a barrier to block the fire. 30．Why does Sonic Fire Tech use low-frequency sound waves? A．They are easier to create with simple electric motors. B．They have been fully tested by research institutions. C．They are the only sound waves that can put out fires. D．They can cover larger areas and avoid harmful noise. 31．What is the author’s main purpose in writing this passage? A．To warn people about the danger of wildfires in suburban areas. B．To compare different ways of fighting wildfires in modern times. C．To introduce an innovative sound-based fire-fighting technology. D．To explain the history of sound wave research in fire control. D In Canada, it often feels as though the year is divided into just two seasons: winter and construction. From repairing sidewalks and roadways to building houses and apartments, nearly all of this work relies on cement (水泥), the essential material in concrete. However, producing cement has a major environmental impact, accounting for roughly eight to ten percent of global greenhouse gas (GHG) release. Researchers at the University of Saskatchewan’s (USask) College of Engineering are investigating whether part of the cement used in concrete could be replaced with biochar (生物炭) to create a more sustainable alternative. Biochar is a fine, carbon-rich material made by burning plant waste in low oxygen. “We reuse agricultural plant wastes like dry grass or crops,” says USask PhD student Ravi Patel. “Normally, this waste is left in fields.” Besides cutting cement use, biochar traps carbon from plants. Patel’s team tested how biochar affects concrete's strength and durability. The researchers mixed concrete with different biochar amounts, and first tested samples for real-world stress and wear. Afterward, they analyzed the material’s microstructure at USask’s Canadian Light Source. Their results showed that biochar-enhanced concrete was stronger and less porous (多孔的) than concrete made with higher amounts of cement. Next, the team will assess how well the biochar-enhanced concrete performs over the longer term. “In  our research, we have studied the new concrete for 56 days,” says Patel. “But we need to check this concrete strength after 1 — 2 years, because the structures are going to stay here for 50 — 70 years. We need to understand the long-term behavior of how the biochar helps to improve the strength properties.” The project could lead to several improvements in the construction industry: concrete production could be more environmentally friendly, using plant waste that otherwise would go to the landfill, and help concrete last longer. “As a researcher, we want to give back to our society, our environment,” says Patel. “It feels really good to get a positive result so that we can actually help address climate change.” 32．Why does the author mention “two seasons” in Canada? A．To describe climate features. B．To stress high cement demand. C．To show environmental issues. D．To explain seasonal changes. 33．What does Patel’s team discover through the test? A．High biochar reduces concrete durability. B．Concrete with more cement is less porous. C．Biochar improves concrete’s strength. D．More cement makes concrete work better. 34．What will the researchers do next? A．Reduce the cost of biochar production. B．Promote the new concrete in construction. C．Attempt other uses of plant waste materials. D．Study the new concrete’s long-term performance. 35．What is the main value of the research project? A．It saves energy in construction. B．It solves seasonal construction limits. C．It helps handle construction waste. D．It offers a more sustainable solution. 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Long, long ago people couldn’t write and they had no books. But they had stories. People learned the stories by heart and taught new ones to one another. Sometimes it was hard to remember them all. 36 The ancient Egyptians wrote their stories on something made from papyrus (纸莎草)  plants. People in other places learned to use papyrus from the Egyptians. 37 So parchment (羊皮纸), made from goatskin, later took its place. In ancient China books looked a little different. At that time, people there used ink to write on bamboo or silk. And then they invented paper. Made of trees, paper was easier and cheaper to make than papyrus or parchment. 38 Paper-making later spread to the West, but there was a big problem with these early books. Every single one had to be copied and written by hand. 39 They carved (雕刻) a page of words into a piece of wood or stone. They could then print the page by spreading ink on the wood or stone and putting it against paper. But it wasn’t until a German printer invented movable, metal letters that books became fast and easy to make. The letters could be used to print copy after copy, and the letters put together again and again to print different pages of words. 40 Once a luxury only the rich could buy, they soon became a treasure everyone could enjoy.

Reading unlocks knowledge and imagination, but this was a world 41 to the blind. In the early 1800s, about 1% of the population was blind, and they faced 42 lives and discrimination. Louis Braille was not born 43 . As a curious three-year-old in France, he 44 injured his eye with a sharp tool while playing. An infection spread, 45 him completely blind. His parents taught him the alphabet (字母) using nails—pounded into wood 46 letters—so he could feel the shapes with his fingers. At age 10, Louis entered the Royal Institute for Blind Youth. Students there 47 using books with raised letters, a slow and difficult process. Louis had always been 48 a simpler method of reading and writing. A(n) 49 came when he learned about a “night writing” code used by soldiers, which used dots and dashes (破折号). 50 , Louis spent years simplifying this idea. He 51 a new system using just six raised dots arranged in different patterns to 52 each letter, with each pattern matching one letter. These tiny dots could express all information. This 53 and elegant system, now known as Braille, was completed by the time he was 15. With the help of a friend who built a machine to press the 54 onto paper, Louis was finally able to write a letter to his mother. His 55 opened up the world of reading and writing for blind people everywhere. 41．A．exposed B．dangerous C．closed D．familiar 42．A．limited B．silent C．comfortable D．independent 43．A．deaf B．blind C．clever D．talented 44．A．eventually B．consequently C．unwillingly D．accidentally 45．A．keeping B．pushing C．allowing D．leaving 46．A．in the shape of B．in place of C．by means of D．with the help of 47．A．communicated B．enjoyed C．read D．memorized 48．A．using B．seeking C．checking D．learning 49．A．breakthrough B．alternative C．message D．challenge 50．A．Puzzled B．Touched C．Admired D．Inspired 51．A．joined up with B．put up with C．came up with D．caught up with 52．A．replace B．represent C．repeat D．remove 53．A．popular B．random C．common D．simple 54．A．texts B．dots C．marks D．lines 55．A．invention B．instruction C．distribution D．discovery 第二节（共10小题：每小题1. 5分, 满分15分） 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。 A groundbreaking achievement in transportation technology 56 (report) recently from China.

His favorite scientific tool had broken, and replacing it required a large amount of money. His mother politely said, “If you want it, you will have to earn it yourself.” So, Sheldon started what he called “The Money Project” — using science to do the everyday job of delivering newspapers. As he had planned, Sheldon’s method was special. He spent days doing research. He studied the weight of the newspaper, planned the best delivery route using maps, and even found the best throwing angle for each house. His planning board was covered in notes and drawings, looking more like a complex puzzle than a simple job plan. On his first Monday, he left home with his prepared basket. The first challenge appeared immediately: the family bicycle was too large for him. After three failed attempts to ride it, he decided to walk, pulling the basket of newspapers behind him. But the basket was so heavy that he soon felt too tired to continue. He quickly thought of a solution. Using an old board, four wheels from broken toys, and some rope, he built a simple homemade cart. Now he could pull the papers easily. Then, the weather, Sheldon had assumed clear weather, turned out different from his forecasts. A light rain began to fall. Sheldon immediately covered the newspaper basket with the plastic he had prepared. This simple action prevented what could have been a real problem. Despite these little episodes (小插曲), his first deliveries were perfect, and he felt pleased. The final challenge came at 17th Elm Street. His goal was the welcome mat, but a large, sleeping dog was lying right on top of it. Sheldon knew getting closer was too dangerous. From where he stood, he could not throw the paper properly. He stood still, his carefully made plan falling apart before this unexpected problem. 注意： 1. 续写词数应为150个左右； 2. 请按如下格式在答题卡的相应位置作答。 After a moment of panic, Sheldon’s scientific mind took over. ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Weeks later, “The Money Project” finally paid off. _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2 / 13 1 / 13 学科网（北京）股份有限公司 $ 2025-2026学年高二英语选择性必修第三册单元自测（湖南专用） Unit 2·培优卷 学校:___________班级：___________姓名：___________分数：___________ （时间：120分钟，满分：150分） 注意事项： 1. 答卷前，考生务必将自己的姓名、准考证号填写在答题卡上。 2. 回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上，写在本试卷上无效。 3. 考试结束后，将本试卷和答题卡一并交回。 第一部分 听力(共两节，满分30分) 做题时，先将答案标在试卷上。录音内容结束后，你将有两分钟的时间将试卷上的答案转涂到答题卡上。 第一节(共5小题;每小题1.5分，满分1.5分) 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话读两遍。 1．When did Philo Farnsworth develop his original idea of sending pictures through the air?

Born in the United States to Nigerian parents, Jessica grew up experiencing two different cultures. This unique background inspired her to think about global challenges in new ways. At just 19 years old, while studying mechanical engineering (机械工程) in college, Jessica and her classmates brainstormed a groundbreaking idea: a soccer ball that could produce electricity. The idea for this invention came during a family trip to the countryside of Nigeria, where she saw firsthand how families struggled without regular electricity. The Soccket Ball, a name combining “soccer” and “socket”, looks like any other soccer ball, but it has a special feature. As you play with it, the ball captures the energy from being kicked and rolled. After a game, this energy can power small devices like LED lights. For many families without regular electricity, this invention can make a big difference. Despite gaining strong support from global organizations and media attention, the product faced unexpected difficulties after its launch. Many users reported that the balls broke or stopped working within a few months, failing to live up to the promised three years of use life. The problems led to criticism from users and negative headlines, putting pressure on Uncharted Play, the company Jessica founded. The team openly admitted that they hadn’t expected the equipment to be so damaged by rough play in the country and promised to revise the design with stronger materials and improved internal parts. Despite these setbacks, Jessica and her team at Uncharted Play continued to work on energy solutions. Their latest invention, a portable jump rope that generates electricity, builds on the Soccket’s success with a more durable, lightweight design. Designed for both children and adults, the jump rope can power small devices like phones or flashlights, expanding the reach of their mission. Jessica’s key goal remains unchanged: to provide clean, renewable energy to people around the world, where electricity shortage limits education, health, and economic opportunities. Her journey proves that even simple, fun activities — like playing soccer or jumping rope — can be transformed into powerful tools to address pressing global affairs. 24．What inspired Jessica to invent the Soccket Ball? A．The energy shortage problem she noticed. B．Her mechanical engineering studies. C．Her unique cross-cultural background. D．Her trip to America with her family. 25．Why did the Soccket Ball disappoint users? A．It performed with high costs. B．It was uncomfortable to play with. C．It can only power small devices. D．It didn’t last as long as expected. 26．What does the underlined word “setbacks” in paragraph 4 mean? A．Challenges. B．Improvements. C．Failures. D．Disadvantages. 27．Which of the following words can best describe Jessica? A．Creative and polite. B．Gifted and selfless. C．Outgoing and careful. D．Ambitious and responsible. 【答案】24．A 25．D 26．A 27．D 【导语】本文是一篇记叙文。本文讲述了发明家杰西卡·马修斯发明能发电的足球和跳绳，为缺电地区提供清洁能源，面对产品挫折仍坚持创新的故事，展现了她的责任感与创造力。    24．细节理解题。根据第2段中“The idea for this invention came during a family trip to the countryside of Nigeria, where she saw firsthand how families struggled without regular electricity.(这项发明的灵感源于一次去尼日利亚乡村的家庭旅行，在那里她亲眼目睹了没有稳定电力供应的家庭生活得多么艰难)”可知，是她亲眼看到的电力短缺问题启发她发明了发电足球。故选A。 25．细节理解题。根据第3段中“Many users reported that the balls broke or stopped working within a few months, failing to live up to the promised three years of use life.(许多用户反馈，这种球在使用几个月后就损坏或无法使用了，没能达到承诺的三年使用寿命)”可知，这款足球让用户失望的原因是使用寿命没有达到预期。故选D。 26．词句猜测题。根据第3段中“The problems led to criticism from users and negative headlines, putting pressure on Uncharted Play, the company Jessica founded.(这些问题引发了用户的批评和负面新闻报道，给杰西卡创办的Uncharted Play公司带来了压力)”，结合第4段开头“Despite these setbacks, Jessica and her team at Uncharted Play continued to work on energy solutions.(尽管有这些……，杰西卡和她在Uncharted Play公司的团队仍继续致力于能源解决方案的研发)”可知，“setbacks”指的是前文提到的产品故障引发的一系列难题，与“Challenges”含义相近。故选A。 27．推理判断题。根据第2段中“Jessica and her classmates brainstormed a groundbreaking idea: a soccer ball that could produce electricity.(杰西卡和同学们集思广益，想出了一个具有开创性的点子：一款可以发电的足球)”以及第4段中“Jessica’s key goal remains unchanged: to provide clean, renewable energy to people around the world, where electricity shortage limits education, health, and economic opportunities.(杰西卡的核心目标始终未变：为全球那些因电力短缺而限制了教育、医疗和经济机会的人们提供清洁的可再生能源)”可知，杰西卡富有创造力，且心怀帮助他人的远大志向与责任感。故选D。 C A wildfire spreads rapidly through dry bushes and grass toward a group of nearby homes in the hills surrounding a Los Angeles suburb. The plants and decorative landscaping around the first house quickly catch fire, but the house itself remains unharmed, holding firm against the flames. Any small sparks that flicker up along its walls die out almost immediately. What’s surprising is that there are no firefighters or fire extinguishers in sight—yet the house stays safe. The secret is that the flames are being put out by sound waves. This kind of fire control using sound, called acoustic fire suppression, may soon become an important tool in fighting wildfires. To understand how this technology works, we first need to know the basic requirements for a fire to burn. For a fire to keep burning, it needs three key things: heat, fuel, and oxygen. If any one of these is taken away, the fire will stop. Sound waves put out fires by pushing oxygen molecules(分子) away from the fuel, making it impossible for the fire to get the air it needs to keep burning. Jeff Bruder, an engineer who once did energy research at NASA, co-founded a company called Sonic Fire Tech to develop a machine that uses this principle. Bruder explains that the machine makes oxygen move so fast that the fire can’t use it, which stops the burning process effectively. The company has already shown that their device can put out fires from as far as 25 feet away. Using sound to fight fires isn’t a new idea—American research groups and universities have been studying this method for more than ten years. However, Albert Simioni, an expert in fire safety, notes that the main difficulty is making this technology work on a larger scale without producing harmful noise. Sonic Fire Tech has solved this problem by using low-frequency sound waves. While earlier research used sound waves between 30 and 60 hertz (赫兹), Sonic’s device uses waves that are 20 hertz or lower. These low-frequency waves can’t be heard by humans and can travel much farther than higher-pitched sound waves. This technology is especially useful because many homes catch fire during wildfires when small burning pieces of wood (called “embers”） blow into attic vents (阁楼通风口). Sonic’s system uses an electric motor to drive a moving component that creates the sound waves. These waves then travel through metal pipes installed on the roof and under the edges of the house, reaching the vents to stop embers from starting fires inside. 28．What can we infer from the first paragraph about the unharmed house? A．It was built with special fire-resistant materials. B．It was protected by an unusual fire-fighting method. C．The wildfire was too weak to damage it. D．All flammable things were removed in advance. 29．What is the basic working principle of acoustic fire suppression? A．It cuts off the fire’s oxygen supply. B．It reduces the temperature around the fire. C．It prevents the fire from moving fast. D．It creates a barrier to block the fire. 30．Why does Sonic Fire Tech use low-frequency sound waves? A．They are easier to create with simple electric motors. B．They have been fully tested by research institutions. C．They are the only sound waves that can put out fires. D．They can cover larger areas and avoid harmful noise. 31．What is the author’s main purpose in writing this passage? A．To warn people about the danger of wildfires in suburban areas. B．To compare different ways of fighting wildfires in modern times. C．To introduce an innovative sound-based fire-fighting technology. D．To explain the history of sound wave research in fire control. 【答案】28．B 29．A 30．D 31．C 【导语】本文是一篇说明文。主要介绍一种利用声波灭火的创新技术，包括其工作原理、优势及实际应用前景。 28．推理判断题。根据第一段“What’s surprising is that there are no firefighters or fire extinguishers in sight—yet the house stays safe. (令人惊讶的是，现场看不到消防员和灭火器，但房子却安然无恙)”，以及第二段“The secret is that the flames are being put out by sound waves. (其中的奥秘在于，火焰是被声波扑灭的)”可知，房子没有受损是因为采用了声波灭火这种非同寻常的防火方法。故选B项。 29．细节理解题。根据第三段中的“Sound waves put out fires by pushing oxygen molecules away from the fuel, making it impossible for the fire to get the air it needs to keep burning.

Sonic Fire Tech has solved this problem by using low-frequency sound waves (主要难点在于让这项技术大规模应用且不产生有害噪音。声波消防技术公司通过使用低频声波解决了这个问题)”和“These low-frequency waves can’t be heard by humans and can travel much farther than higher-pitched sound waves. (这些低频声波人类听不到，且传播距离比高频声波远得多)”可知，该公司使用低频声波的原因是其能覆盖更大范围且不会产生有害噪音。故选D项。 31．推理判断题。通读全文，文章以洛杉矶郊区一栋在野火中安然无恙的房子为切入点，引出声波灭火技术，随后介绍该技术的工作原理、发展难点及解决方案。短文的目的是介绍一种创新的声波灭火技术。故选C项。 D In Canada, it often feels as though the year is divided into just two seasons: winter and construction. From repairing sidewalks and roadways to building houses and apartments, nearly all of this work relies on cement (水泥), the essential material in concrete. However, producing cement has a major environmental impact, accounting for roughly eight to ten percent of global greenhouse gas (GHG) release. Researchers at the University of Saskatchewan’s (USask) College of Engineering are investigating whether part of the cement used in concrete could be replaced with biochar (生物炭) to create a more sustainable alternative. Biochar is a fine, carbon-rich material made by burning plant waste in low oxygen. “We reuse agricultural plant wastes like dry grass or crops,” says USask PhD student Ravi Patel. “Normally, this waste is left in fields.” Besides cutting cement use, biochar traps carbon from plants. Patel’s team tested how biochar affects concrete's strength and durability. The researchers mixed concrete with different biochar amounts, and first tested samples for real-world stress and wear. Afterward, they analyzed the material’s microstructure at USask’s Canadian Light Source. Their results showed that biochar-enhanced concrete was stronger and less porous (多孔的) than concrete made with higher amounts of cement. Next, the team will assess how well the biochar-enhanced concrete performs over the longer term. “In  our research, we have studied the new concrete for 56 days,” says Patel. “But we need to check this concrete strength after 1 — 2 years, because the structures are going to stay here for 50 — 70 years. We need to understand the long-term behavior of how the biochar helps to improve the strength properties.” The project could lead to several improvements in the construction industry: concrete production could be more environmentally friendly, using plant waste that otherwise would go to the landfill, and help concrete last longer. “As a researcher, we want to give back to our society, our environment,” says Patel. “It feels really good to get a positive result so that we can actually help address climate change.” 32．Why does the author mention “two seasons” in Canada? A．To describe climate features. B．To stress high cement demand. C．To show environmental issues. D．To explain seasonal changes. 33．What does Patel’s team discover through the test? A．High biochar reduces concrete durability. B．Concrete with more cement is less porous. C．Biochar improves concrete’s strength. D．More cement makes concrete work better. 34．What will the researchers do next? A．Reduce the cost of biochar production. B．Promote the new concrete in construction. C．Attempt other uses of plant waste materials. D．Study the new concrete’s long-term performance. 35．What is the main value of the research project? A．It saves energy in construction. B．It solves seasonal construction limits. C．It helps handle construction waste. D．It offers a more sustainable solution. 【答案】32．B 33．C 34．D 35．D 【导语】本文是一篇说明文。文章主要介绍了加拿大萨斯喀彻温大学工程学院的研究人员正在研究能否用生物炭替代混凝土中的部分水泥，以创造更可持续的替代品，阐述了研究过程、成果及未来计划和该研究项目的价值。 32．推理判断题。根据第一段“In Canada, it often feels as though the year is divided into just two seasons: winter and construction. From repairing sidewalks and roadways to building houses and apartments, nearly all of this work relies on cement (水泥), the essential material in concrete.(在加拿大，人们常常觉得一年只有两个季节：冬季和施工季。从修理人行道和道路到建造房屋和公寓，几乎所有这些工作都依赖于水泥，水泥是混凝土的基本材料。)”可推知，作者提到加拿大的“两个季节”是为了强调对水泥的高需求。故选B项。 33．细节理解题。根据第四段中的“Their results showed that biochar-enhanced concrete was stronger and less porous (多孔的) than concrete made with higher amounts of cement.(他们的结果显示，与用大量水泥制成的混凝土相比，生物炭增强的混凝土更强，孔隙更少。)”可知，Patel的团队通过测试发现生物炭提高了混凝土的强度。故选C项。 34．细节理解题。根据第五段中的“Next, the team will assess how well the biochar-enhanced concrete performs over the longer term.(接下来，该团队将评估生物炭增强混凝土在较长时间内的性能。)”可知，研究人员下一步将研究新混凝土的长期性能。故选D项。 35．推理判断题。根据第二段“However, producing cement has a major environmental impact, accounting for roughly eight to ten percent of global greenhouse gas (GHG) release. Researchers at the University of Saskatchewan’s (USask) College of Engineering are investigating whether part of the cement used in concrete could be replaced with biochar (生物炭) to create a more sustainable alternative.(然而，水泥生产对环境有重大影响，约占全球温室气体排放量的8%至10%。萨斯喀彻温大学（USask）工程学院的研究人员正在研究能否用生物炭替代混凝土中的部分水泥，以创造更可持续的替代品。)”以及最后一段中的“The project could lead to several improvements in the construction industry: concrete production could be more environmentally friendly, using plant waste that otherwise would go to the landfill, and help concrete last longer.(该项目可能会给建筑业带来几项改进：混凝土生产可以更环保，使用原本会被送往垃圾填埋场的植物废弃物，并有助于延长混凝土的寿命。)”可推知，该研究项目的主要价值是它提供了一个更可持续的解决方案。故选D项。 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Long, long ago people couldn’t write and they had no books. But they had stories. People learned the stories by heart and taught new ones to one another. Sometimes it was hard to remember them all. 36 The ancient Egyptians wrote their stories on something made from papyrus (纸莎草)  plants. People in other places learned to use papyrus from the Egyptians. 37 So parchment (羊皮纸), made from goatskin, later took its place. In ancient China books looked a little different. At that time, people there used ink to write on bamboo or silk. And then they invented paper. Made of trees, paper was easier and cheaper to make than papyrus or parchment. 38 Paper-making later spread to the West, but there was a big problem with these early books. Every single one had to be copied and written by hand. 39 They carved (雕刻) a page of words into a piece of wood or stone. They could then print the page by spreading ink on the wood or stone and putting it against paper. But it wasn’t until a German printer invented movable, metal letters that books became fast and easy to make. The letters could be used to print copy after copy, and the letters put together again and again to print different pages of words. 40 Once a luxury only the rich could buy, they soon became a treasure everyone could enjoy. A．But papyrus grew mainly in Egypt. B．It took years to finish making just one book. C．Finally books could be printed by the thousands. D．Things grew a little easier when writing was invented. E．Its surface was smoother and better for writing on too. F．Books in the West didn’t change for a long time after that. G．The Chinese were the first to think of a way to speed things up a little. 【答案】36．D 37．A 38．E 39．G 40．C 【导语】本文是一篇说明文。文章按时间顺序介绍了书籍载体的演变历史，从口耳相传到文字记录，再到埃及纸莎草纸、中国竹简、丝绸与纸、以及欧洲羊皮纸的相继使用，最后重点讲述了中国雕版印刷术的发明如何使书籍得以大规模、快速地生产，从而普及开来。 36．上文“Long, long ago people couldn’t write and they had no books. But they had stories. People learned the stories by heart and taught new ones to one another. Sometimes it was hard to remember them all. (很久很久以前，人们不会写字，也没有书。但他们有故事。人们用心记住故事并互相教授新的。有时很难记住所有的故事)”描述了文字发明前，人们依靠记忆和口述传承故事的困难。D选项“Things grew a little easier when writing was invented. (当文字被发明时，情况变得稍微容易了一些)”承接上文，明确指出“文字的发明”是解决上述困难的关键转折点。下文开始讲述古埃及人在“纸莎草”上书写故事，正是对“writing was invented”之后情况的具体展开。D选项起到了从“史前”过渡到“有文字记录历史”的作用。故选D项。 37．上文“People in other places learned to use papyrus from the Egyptians. (其他地方的人们向埃及人学会了使用纸莎草纸)”指出纸莎草纸的使用传播到了埃及以外的地区。A选项“But papyrus grew mainly in Egypt. (但是纸莎草主要生长在埃及)”与上文构成转折关系，指出了纸莎草纸推广面临的一个根本性限制：其原材料(纸莎草)的地域局限性。下文“So parchment (羊皮纸), made from goatskin, later took its place. (所以，用山羊皮制成的羊皮纸后来取代了它)”则顺理成章地说明了由于纸莎草原材料短缺(主要在埃及)，人们找到了替代品——羊皮纸。A选项解释了为何需要寻找“parchment”这一替代品，是逻辑链条中的关键一环。故选A项。 38．上文“Made of trees, paper was easier and cheaper to make than papyrus or parchment. (由树木制成，纸比纸莎草纸或羊皮纸更容易且更便宜制造)”介绍了纸相对于前两种材料的优点(易得、便宜)。E选项“Its surface was smoother and better for writing on too. (它的表面也更光滑，更适合书写)”通过“too (也)”这个递进词，进一步补充了纸的另一个优点——书写体验更好。这里的“Its surface”指代的就是上文提到的“paper (纸)”的表面。该选项使对纸的优点描述更加全面。下文“Paper-making later spread to the West, but there was a big problem with these early books. (造纸术后来传播到西方，但这些早期书籍有一个大问题)”则转向讨论纸普及后书籍制作的另一个瓶颈，E选项的补充与下文形成顺畅的语义衔接。故选E项。 39．下文“They carved (雕刻) a page of words into a piece of wood or stone. They could then print the page by spreading ink on the wood or stone and putting it against paper. (他们将一页文字雕刻在一块木头或石头上。然后他们可以通过在木头或石头上涂上墨水并将其压在纸上来印刷这一页)”详细描述了一种早期的印刷技术(雕版印刷)。G选项“The Chinese were the first to think of a way to speed things up a little. (中国人最先想到一个方法来稍微加快速度)”位于段首，作为总起句，点明本段要介绍的是中国人发明的、旨在加速书籍生产的方法。下文的雕版印刷正是对“a way to speed things up”的具体说明。上下文形成“总括-详解”的关系，且G选项中的“The Chinese”与下文的“They”形成指代关系。故选G项。 40．上文“But it wasn’t until a German printer invented movable, metal letters that books became fast and easy to make. The letters could be used to print copy after copy, and the letters put together again and again to print different pages of words. (但直到一位德国印刷工人发明了可移动的金属活字，书籍才变得快速且易于制作。这些活字可以用来印刷一份又一份副本，并且可以反复组合来印刷不同页的文字)”介绍了活字印刷术的发明及其带来的革命性变化(快速、批量、可重复使用)。C选项“Finally books could be printed by the thousands. (最终，书籍可以成千上万地印刷了)”是对上文活字印刷术效果的总结和升华，用“by the thousands”生动地描绘了书籍生产从手工复制到工业化规模印刷的巨大飞跃。下文“Once a luxury only the rich could buy, they soon became a treasure everyone could enjoy. (曾经是只有富人才能购买的奢侈品，它们很快变成了人人都能享受的珍宝)”则是在C选项的基础上，进一步阐述书籍大规模生产带来的社会影响——普及化。C选项是连接技术革新与社会影响之间的关键句。故选C项。 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 The invention of the printing press made books widely available, which expanded education and knowledge. Reading unlocks knowledge and imagination, but this was a world 41 to the blind. In the early 1800s, about 1% of the population was blind, and they faced 42 lives and discrimination. Louis Braille was not born 43 . As a curious three-year-old in France, he 44 injured his eye with a sharp tool while playing. An infection spread, 45 him completely blind. His parents taught him the alphabet (字母) using nails—pounded into wood 46 letters—so he could feel the shapes with his fingers. At age 10, Louis entered the Royal Institute for Blind Youth. Students there 47 using books with raised letters, a slow and difficult process. Louis had always been 48 a simpler method of reading and writing. A(n) 49 came when he learned about a “night writing” code used by soldiers, which used dots and dashes (破折号). 50 , Louis spent years simplifying this idea. He 51 a new system using just six raised dots arranged in different patterns to 52 each letter, with each pattern matching one letter. These tiny dots could express all information. This 53 and elegant system, now known as Braille, was completed by the time he was 15. With the help of a friend who built a machine to press the 54 onto paper, Louis was finally able to write a letter to his mother. His 55 opened up the world of reading and writing for blind people everywhere. 41．A．exposed B．dangerous C．closed D．familiar 42．A．limited B．silent C．comfortable D．independent 43．A．deaf B．blind C．clever D．talented 44．A．eventually B．consequently C．unwillingly D．accidentally 45．A．keeping B．pushing C．allowing D．leaving 46．A．in the shape of B．in place of C．by means of D．with the help of 47．A．communicated B．enjoyed C．read D．memorized 48．A．using B．seeking C．checking D．learning 49．A．breakthrough B．alternative C．message D．challenge 50．A．Puzzled B．Touched C．Admired D．Inspired 51．A．joined up with B．put up with C．came up with D．caught up with 52．A．replace B．represent C．repeat D．remove 53．A．popular B．random C．common D．simple 54．A．texts B．dots C．marks D．lines 55．A．invention B．instruction C．distribution D．discovery 【答案】 41．C 42．A 43．B 44．D 45．D 46．A 47．C 48．B 49．A 50．D 51．C 52．B 53．D 54．B 55．A 【导语】本文是一篇记叙文，主要讲的是布莱叶盲文的发明过程及其对盲人阅读和写作领域的革命性影响。 41．考查形容词词义辨析。句意：阅读能够开启知识与想象的大门，但对于盲人来说，这个世界是封闭的。A. exposed暴露的；B. dangerous危险的；C. closed关闭的；D. familiar熟悉的。根据上文“Reading”和下文“to the blind”可知，盲人看不见，所以他们读不了书，知识的世界对他们来说是关闭的。故选C。 42．考查形容词词义辨析。句意：在19世纪初，大约1%的人口是盲人，他们面临着有限的生活和歧视。A. limited有限的；B. silent沉默的；C. comfortable舒适的；D. independent独立的。根据“and discrimination”以及后文描述盲人生活的不便等内容可知，盲人面临的生活是有限的，有很多限制。故选A。 43．考查形容词词义辨析。句意：Louis Braille并非天生失明。A. deaf聋的；B. blind失明的；C. clever聪明的；D. talented有天赋的。根据后文“injured his eye with a sharp tool while playing”描述他受伤后失明可知，这里说他不是生来就失明。故选B。 44．考查副词词义辨析。句意：在他三岁那年，当时好奇心旺盛的他在法国玩耍时不小心用一把锋利的工具弄伤了自己的眼睛。A. eventually最终；B. consequently因此；C. unwillingly不情愿地；D. accidentally意外地。根据下文“injured his eye with a sharp tool while playing”可知，是在玩耍时意外受伤。故选D。 45．考查动词词义辨析。句意：感染扩散，使他完全失明。A. keeping保持；B. pushing推；C. allowing允许；D. leaving使……处于（某种状态）。根据“An infection spread”可知，感染扩散导致他完全失明，“leave sb. + adj.”表示“使某人处于某种状态”。故选D。 46．考查介词短语辨析。句意：他的父母用钉在木头上的呈字母形状的钉子教他字母表，这样他就可以用手指感受形状。A. in the shape of呈……形状；B. in place of代替；C. by means of通过……方式；D. with the help of在……的帮助下。根据上文“nails—pounded into wood”以及“letters”可知，钉子是呈字母形状钉在木头上的。故选A。 47．考查动词词义辨析。句意：那里的学生阅读用凸起字母写成的书，这是一个缓慢而困难的过程。A. communicated交流；B. enjoyed享受；C. read阅读；D. memorized记忆。根据“using books with raised letters”可知，是用凸起字母的书进行阅读。故选C。 48．考查动词词义辨析。句意：路易斯一直在寻找更简单的读写方法。A. using使用；B. seeking寻找；C. checking检查；D. learning学习。根据“a simpler method of reading and writing”可知，是一直在寻找更简单的方法。故选B。 49．考查名词词义辨析。句意：当他了解到士兵使用的一种“夜间书写”密码时，有了突破，这种密码使用点和破折号。A. breakthrough突破；B. alternative替代品；C. message信息；D. challenge挑战。根据后文“Louis spent years simplifying this idea”他简化这种密码创造出新的系统可知，这里说有了突破。故选A。 50．考查形容词词义辨析。句意：受此启发，路易斯花了数年时间简化这个想法。A.

His favorite scientific tool had broken, and replacing it required a large amount of money. His mother politely said, “If you want it, you will have to earn it yourself.” So, Sheldon started what he called “The Money Project” — using science to do the everyday job of delivering newspapers. As he had planned, Sheldon’s method was special. He spent days doing research. He studied the weight of the newspaper, planned the best delivery route using maps, and even found the best throwing angle for each house. His planning board was covered in notes and drawings, looking more like a complex puzzle than a simple job plan. On his first Monday, he left home with his prepared basket. The first challenge appeared immediately: the family bicycle was too large for him. After three failed attempts to ride it, he decided to walk, pulling the basket of newspapers behind him. But the basket was so heavy that he soon felt too tired to continue. He quickly thought of a solution. Using an old board, four wheels from broken toys, and some rope, he built a simple homemade cart. Now he could pull the papers easily. Then, the weather, Sheldon had assumed clear weather, turned out different from his forecasts. A light rain began to fall. Sheldon immediately covered the newspaper basket with the plastic he had prepared. This simple action prevented what could have been a real problem. Despite these little episodes (小插曲), his first deliveries were perfect, and he felt pleased. The final challenge came at 17th Elm Street. His goal was the welcome mat, but a large, sleeping dog was lying right on top of it. Sheldon knew getting closer was too dangerous. From where he stood, he could not throw the paper properly. He stood still, his carefully made plan falling apart before this unexpected problem. 注意： 1. 续写词数应为150个左右； 2. 请按如下格式在答题卡的相应位置作答。 After a moment of panic, Sheldon’s scientific mind took over. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Weeks later, “The Money Project” finally paid off. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】     After a moment of panic, Sheldon’s scientific mind took over. Noticing the low fence beside the steps, he quickly calculated the distance and the required throwing angle. He rolled the newspaper into a tight tube. With a precise underhand throw, he sent the paper sliding smoothly along the fence. It traveled in a perfect bend around the sleeping dog and came to rest right at the front door. A small smile appeared on his face as he continued his route, the crisis expertly solved through physics.     Weeks later, “The Money Project” finally paid off. Sheldon placed his carefully saved money on the counter, receiving the long-wanted scientific tool. His mother’s eyes met his, shining with pride.

Born in the United States to Nigerian parents, Jessica grew up experiencing two different cultures. This unique background inspired her to think about global challenges in new ways. At just 19 years old, while studying mechanical engineering (机械工程) in college, Jessica and her classmates brainstormed a groundbreaking idea: a soccer ball that could produce electricity. The idea for this invention came during a family trip to the countryside of Nigeria, where she saw firsthand how families struggled without regular electricity. The Soccket Ball, a name combining “soccer” and “socket”, looks like any other soccer ball, but it has a special feature. As you play with it, the ball captures the energy from being kicked and rolled. After a game, this energy can power small devices like LED lights. For many families without regular electricity, this invention can make a big difference. Despite gaining strong support from global organizations and media attention, the product faced unexpected difficulties after its launch. Many users reported that the balls broke or stopped working within a few months, failing to live up to the promised three years of use life. The problems led to criticism from users and negative headlines, putting pressure on Uncharted Play, the company Jessica founded. The team openly admitted that they hadn’t expected the equipment to be so damaged by rough play in the country and promised to revise the design with stronger materials and improved internal parts. Despite these setbacks, Jessica and her team at Uncharted Play continued to work on energy solutions. Their latest invention, a portable jump rope that generates electricity, builds on the Soccket’s success with a more durable, lightweight design. Designed for both children and adults, the jump rope can power small devices like phones or flashlights, expanding the reach of their mission. Jessica’s key goal remains unchanged: to provide clean, renewable energy to people around the world, where electricity shortage limits education, health, and economic opportunities. Her journey proves that even simple, fun activities — like playing soccer or jumping rope — can be transformed into powerful tools to address pressing global affairs. 24．What inspired Jessica to invent the Soccket Ball? A．The energy shortage problem she noticed. B．Her mechanical engineering studies. C．Her unique cross-cultural background. D．Her trip to America with her family. 25．Why did the Soccket Ball disappoint users? A．It performed with high costs. B．It was uncomfortable to play with. C．It can only power small devices. D．It didn’t last as long as expected. 26．What does the underlined word “setbacks” in paragraph 4 mean? A．Challenges. B．Improvements. C．Failures. D．Disadvantages. 27．Which of the following words can best describe Jessica? A．Creative and polite. B．Gifted and selfless. C．Outgoing and careful. D．Ambitious and responsible. C A wildfire spreads rapidly through dry bushes and grass toward a group of nearby homes in the hills surrounding a Los Angeles suburb. The plants and decorative landscaping around the first house quickly catch fire, but the house itself remains unharmed, holding firm against the flames. Any small sparks that flicker up along its walls die out almost immediately. What’s surprising is that there are no firefighters or fire extinguishers in sight—yet the house stays safe. The secret is that the flames are being put out by sound waves. This kind of fire control using sound, called acoustic fire suppression, may soon become an important tool in fighting wildfires. To understand how this technology works, we first need to know the basic requirements for a fire to burn. For a fire to keep burning, it needs three key things: heat, fuel, and oxygen. If any one of these is taken away, the fire will stop. Sound waves put out fires by pushing oxygen molecules(分子) away from the fuel, making it impossible for the fire to get the air it needs to keep burning. Jeff Bruder, an engineer who once did energy research at NASA, co-founded a company called Sonic Fire Tech to develop a machine that uses this principle. Bruder explains that the machine makes oxygen move so fast that the fire can’t use it, which stops the burning process effectively. The company has already shown that their device can put out fires from as far as 25 feet away. Using sound to fight fires isn’t a new idea—American research groups and universities have been studying this method for more than ten years. However, Albert Simioni, an expert in fire safety, notes that the main difficulty is making this technology work on a larger scale without producing harmful noise. Sonic Fire Tech has solved this problem by using low-frequency sound waves. While earlier research used sound waves between 30 and 60 hertz (赫兹), Sonic’s device uses waves that are 20 hertz or lower. These low-frequency waves can’t be heard by humans and can travel much farther than higher-pitched sound waves. This technology is especially useful because many homes catch fire during wildfires when small burning pieces of wood (called “embers”） blow into attic vents (阁楼通风口). Sonic’s system uses an electric motor to drive a moving component that creates the sound waves. These waves then travel through metal pipes installed on the roof and under the edges of the house, reaching the vents to stop embers from starting fires inside. 28．What can we infer from the first paragraph about the unharmed house? A．It was built with special fire-resistant materials. B．It was protected by an unusual fire-fighting method. C．The wildfire was too weak to damage it. D．All flammable things were removed in advance. 29．What is the basic working principle of acoustic fire suppression? A．It cuts off the fire’s oxygen supply. B．It reduces the temperature around the fire. C．It prevents the fire from moving fast. D．It creates a barrier to block the fire. 30．Why does Sonic Fire Tech use low-frequency sound waves? A．They are easier to create with simple electric motors. B．They have been fully tested by research institutions. C．They are the only sound waves that can put out fires. D．They can cover larger areas and avoid harmful noise. 31．What is the author’s main purpose in writing this passage? A．To warn people about the danger of wildfires in suburban areas. B．To compare different ways of fighting wildfires in modern times. C．To introduce an innovative sound-based fire-fighting technology. D．To explain the history of sound wave research in fire control. D In Canada, it often feels as though the year is divided into just two seasons: winter and construction. From repairing sidewalks and roadways to building houses and apartments, nearly all of this work relies on cement (水泥), the essential material in concrete. However, producing cement has a major environmental impact, accounting for roughly eight to ten percent of global greenhouse gas (GHG) release. Researchers at the University of Saskatchewan’s (USask) College of Engineering are investigating whether part of the cement used in concrete could be replaced with biochar (生物炭) to create a more sustainable alternative. Biochar is a fine, carbon-rich material made by burning plant waste in low oxygen. “We reuse agricultural plant wastes like dry grass or crops,” says USask PhD student Ravi Patel. “Normally, this waste is left in fields.” Besides cutting cement use, biochar traps carbon from plants. Patel’s team tested how biochar affects concrete's strength and durability. The researchers mixed concrete with different biochar amounts, and first tested samples for real-world stress and wear. Afterward, they analyzed the material’s microstructure at USask’s Canadian Light Source. Their results showed that biochar-enhanced concrete was stronger and less porous (多孔的) than concrete made with higher amounts of cement. Next, the team will assess how well the biochar-enhanced concrete performs over the longer term. “In  our research, we have studied the new concrete for 56 days,” says Patel. “But we need to check this concrete strength after 1 — 2 years, because the structures are going to stay here for 50 — 70 years. We need to understand the long-term behavior of how the biochar helps to improve the strength properties.” The project could lead to several improvements in the construction industry: concrete production could be more environmentally friendly, using plant waste that otherwise would go to the landfill, and help concrete last longer. “As a researcher, we want to give back to our society, our environment,” says Patel. “It feels really good to get a positive result so that we can actually help address climate change.” 32．Why does the author mention “two seasons” in Canada? A．To describe climate features. B．To stress high cement demand. C．To show environmental issues. D．To explain seasonal changes. 33．What does Patel’s team discover through the test? A．High biochar reduces concrete durability. B．Concrete with more cement is less porous. C．Biochar improves concrete’s strength. D．More cement makes concrete work better. 34．What will the researchers do next? A．Reduce the cost of biochar production. B．Promote the new concrete in construction. C．Attempt other uses of plant waste materials. D．Study the new concrete’s long-term performance. 35．What is the main value of the research project? A．It saves energy in construction. B．It solves seasonal construction limits. C．It helps handle construction waste. D．It offers a more sustainable solution. 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Long, long ago people couldn’t write and they had no books. But they had stories. People learned the stories by heart and taught new ones to one another. Sometimes it was hard to remember them all. 36 The ancient Egyptians wrote their stories on something made from papyrus (纸莎草)  plants. People in other places learned to use papyrus from the Egyptians. 37 So parchment (羊皮纸), made from goatskin, later took its place. In ancient China books looked a little different. At that time, people there used ink to write on bamboo or silk. And then they invented paper. Made of trees, paper was easier and cheaper to make than papyrus or parchment. 38 Paper-making later spread to the West, but there was a big problem with these early books. Every single one had to be copied and written by hand. 39 They carved (雕刻) a page of words into a piece of wood or stone. They could then print the page by spreading ink on the wood or stone and putting it against paper. But it wasn’t until a German printer invented movable, metal letters that books became fast and easy to make. The letters could be used to print copy after copy, and the letters put together again and again to print different pages of words. 40 Once a luxury only the rich could buy, they soon became a treasure everyone could enjoy. A．But papyrus grew mainly in Egypt. B．It took years to finish making just one book. C．Finally books could be printed by the thousands. D．Things grew a little easier when writing was invented. E．Its surface was smoother and better for writing on too. F．Books in the West didn’t change for a long time after that. G．The Chinese were the first to think of a way to speed things up a little. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 The invention of the printing press made books widely available, which expanded education and knowledge. Reading unlocks knowledge and imagination, but this was a world 41 to the blind. In the early 1800s, about 1% of the population was blind, and they faced 42 lives and discrimination. Louis Braille was not born 43 . As a curious three-year-old in France, he 44 injured his eye with a sharp tool while playing. An infection spread, 45 him completely blind. His parents taught him the alphabet (字母) using nails—pounded into wood 46 letters—so he could feel the shapes with his fingers. At age 10, Louis entered the Royal Institute for Blind Youth. Students there 47 using books with raised letters, a slow and difficult process. Louis had always been 48 a simpler method of reading and writing. A(n) 49 came when he learned about a “night writing” code used by soldiers, which used dots and dashes (破折号). 50 , Louis spent years simplifying this idea. He 51 a new system using just six raised dots arranged in different patterns to 52 each letter, with each pattern matching one letter. These tiny dots could express all information. This 53 and elegant system, now known as Braille, was completed by the time he was 15. With the help of a friend who built a machine to press the 54 onto paper, Louis was finally able to write a letter to his mother. His 55 opened up the world of reading and writing for blind people everywhere. 41．A．exposed B．dangerous C．closed D．familiar 42．A．limited B．silent C．comfortable D．independent 43．A．deaf B．blind C．clever D．talented 44．A．eventually B．consequently C．unwillingly D．accidentally 45．A．keeping B．pushing C．allowing D．leaving 46．A．in the shape of B．in place of C．by means of D．with the help of 47．A．communicated B．enjoyed C．read D．memorized 48．A．using B．seeking C．checking D．learning 49．A．breakthrough B．alternative C．message D．challenge 50．A．Puzzled B．Touched C．Admired D．Inspired 51．A．joined up with B．put up with C．came up with D．caught up with 52．A．replace B．represent C．repeat D．remove 53．A．popular B．random C．common D．simple 54．A．texts B．dots C．marks D．lines 55．A．invention B．instruction C．distribution D．discovery 第二节（共10小题：每小题1. 5分, 满分15分） 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。 A groundbreaking achievement in transportation technology 56 (report) recently from China.

His favorite scientific tool had broken, and replacing it required a large amount of money. His mother politely said, “If you want it, you will have to earn it yourself.” So, Sheldon started what he called “The Money Project” — using science to do the everyday job of delivering newspapers. As he had planned, Sheldon’s method was special. He spent days doing research. He studied the weight of the newspaper, planned the best delivery route using maps, and even found the best throwing angle for each house. His planning board was covered in notes and drawings, looking more like a complex puzzle than a simple job plan. On his first Monday, he left home with his prepared basket. The first challenge appeared immediately: the family bicycle was too large for him. After three failed attempts to ride it, he decided to walk, pulling the basket of newspapers behind him. But the basket was so heavy that he soon felt too tired to continue. He quickly thought of a solution. Using an old board, four wheels from broken toys, and some rope, he built a simple homemade cart. Now he could pull the papers easily. Then, the weather, Sheldon had assumed clear weather, turned out different from his forecasts. A light rain began to fall. Sheldon immediately covered the newspaper basket with the plastic he had prepared. This simple action prevented what could have been a real problem. Despite these little episodes (小插曲), his first deliveries were perfect, and he felt pleased. The final challenge came at 17th Elm Street. His goal was the welcome mat, but a large, sleeping dog was lying right on top of it. Sheldon knew getting closer was too dangerous. From where he stood, he could not throw the paper properly. He stood still, his carefully made plan falling apart before this unexpected problem. 注意： 1. 续写词数应为150个左右； 2. 请按如下格式在答题卡的相应位置作答。 After a moment of panic, Sheldon’s scientific mind took over. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Weeks later, “The Money Project” finally paid off. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 第1页 共4页 ◎ 第2页 共4页 第1页 共4页 ◎ 第2页 共4页 学科网（北京）股份有限公司 $
