(24-25高二下·甘肃·期末)Astronauts do a lot to prepare for the many things that can go wrong during space travel. But they can’t be experts in everything. That’s why NASA is testing to see if robots can fill in some of the gaps.
A robot MIRA took an important step in that direction. Scientists succeeded in testing the robot’s ability to perform operations while on the International Space Station (ISS). And what’s more, they controlled the robot remotely from Earth.
The robot was designed by a Lincoln, Nebraska-based company called Virtual Incision. Robots have long been used in surgery, but MIRA is the first miniature version of robotic-assisted surgery technology in development. The company said it’s about 1,000 times lighter than previous technologies, making it ideal for space travel where every pound matters.
The goal of the experiment was to see if and how MIRA’s surgical capabilities would be affected by zero gravity. It attempted to perform a series of surgical tasks on simulated(模拟) human tissue while aboard the ISS, remotely controlled by six researchers in Lincoln, Nebraska. The robot performed a dissection(解剖) task common in surgeries, using its left hand to create tension in the tissue and its right to dissect the tissue with scissors.
Researchers reported that the robot was able to successfully complete the task. As to the question of how zero gravity affects the robot’s surgical skills, they said it would take a few weeks or months before results were sent back to Earth.
One goal of the research is to develop technology that could one day allow doctors to perform surgeries on astronauts remotely from Earth. It could also have a big impact on Earth, helping those who don’t have access to a surgeon get the help they need.
1.What is the function of Paragraph 1?
A.To present a phenomenon. B.To introduce the topic.

D.Robots Took the Place of doctors in Surgeries
(24-25高二下·黑龙江大庆·期末)For over 1,800 years, doctors have used silk to sew wounds. Now, biomedical engineers are using it to make different types of medical implants (植入物).
Doctors like silk for a variety of reasons. First, silk is a natural material that will break down in the body over time. So any implanted parts made of silk don’t have to be removed by surgery. Plus, not many people are sensitive to it.
The materials currently used to make silk parts are made of proteins called silk fibroin. They are typically dissolved (溶解) in water until needed. But like all proteins, silk proteins can break down over time. Besides, all that water adds a lot of weight and volume to the silk materials as they’re stored, which makes those materials expensive to ship from place to place.
David Kaplan from Tutts University and his colleagues set out to solve those problems. First, they put the silk proteins into salt. Next, they added water to the mixture. They then added a chemical called liquid nitrogen. Afterward, they put the icy mix into a place where the air pressure was very low. That combination of very low temperature and pressure caused water to disappear. Finally, the researchers turned the freeze-dried material into a powder.
Powdered silk could help make really strong medical implants (such as the tools used to hold a broken bone together), which is a great breakthrough in the medical field. Besides, being biocompatible (生物相容的) is just the icing on the cake. It enables powdered silk to have another possible use: putting drugs into the implants. The implants could slowly release a drug over time. That way, patients might not need to take pills or get painful injections.
Powdered silk is easy to work with, too. It is chemically stable and can last up to two years on the shelf. Plus, it’s lightweight because a lot of the water has been removed. So it doesn’t cost as much to ship the material.
1.Why do doctors like silk?
A.Its long history. B.Its rich variety. C.Its affordable price. D.Its outstanding nature.
2.What function does liquid nitrogen serve in David’s research?
A.To separate salt from the mixture. B.To produce low temperature.
C.To keep the low pressure. D.To make a mixture.
3.What does the underlined part “the icing on the cake” in paragraph 5 mean?
A.A piece of cake. B.Another bonus. C.A coincidence. D.A tendency.
4.What does the text mainly focus on?
A.The benefits of powdered silk.
B.Silk’s wide applications in our life.
C.The process of making medical implants.
D.A unique way of turning silk into medical materials.
(24-25高二下·辽宁大连·期末)Can you imagine a house made from mushrooms? What benefits could such a material offer compared to traditional building materials?
In the development of sustainable construction, Czech researchers and architects have showcased a building made primarily from mycelia (菌丝). The innovative house named Samorost is 3.5-meter-tall and 7-meter-long, using 1,800 kilograms of mycelia. Samorost is designed to serve as both a functional structure and a striking example of how mycelia can be used to replace traditional, fossil-fuel-based materials like polystyrene (聚苯乙烯) for environmental benefits.
The mycelia used in the construction of Samorost are made from the root system of a species of mushroom, known for its durability (耐用性) and strength. Mycelia, when combined with natural, renewable materials such as wood, become a lightweight yet durable building material. Besides, unlike polystyrene, mycelia are biodegradable and produce significantly lower CO₂ emissions during, production. Additionally, mycelia have numerous potential applications in construction, such as being used as structural components like walls. As the material is both fire-resistant and highly customizable, mycelia can be used for furniture or supporting walls.
However, experts caution that while mycelia show promise, their widespread use in construction may take time. According to Katerina Sysova, an architect at the Czech Technical University, mycelia are not yet suited for every application, such as external building materials in multi - story buildings, where wet atmosphere could compromise their performance.
Still, with growing support from the European Union’s sustainability initiatives and increasing demand for environmentally friendly solutions, mycelia - based construction could become the mainstream in the coming years.

(24-25高二下·四川成都·期末)Scientists have discovered a new technique by which light can be bent around corners, inspired by the way clouds scatter (散射) sunlight. This type of light-bending could lead to improvements in many fields such as medical imaging and electronics cooling.
Daniele Faccio at the University of Glasgow, UK, and his workmates say they are shocked that this type of light scattering wasn’t noticed before. It works on the same basis as clouds, snow and other white materials that absorb light: once photons (光子) hit the surface of such a material, they are scattered in all directions.
“The light goes around and tries to get in,” says Faccio. “And eventually what happens is that it just gets reflected back because it can’t get in. This is this scattering.”
To copy this process, the team 3D printed objects from a special white material while leaving thin tunnels (通路) within. When light is shone at the material, it travels into these tunnels and is scattered — just as light is on snow or clouds. However, instead of scattering randomly in every direction, the photons are directed to return to the tunnels by the material. The team put this to use, creating a range of objects that control light in an organised way. The researchers say their material improves light transmission much better than those without the same tunnels, and also allows it to be directed around curves.
This method of light-bending could make use of existing tunnels of some special materials to provide new ways to carry out medical imaging. Faccio says the exact same way also works to direct heat and neutrons, and could therefore also find use in a range of engineering applications such as cooling systems.

(24-25高二下·辽宁·期末)A team of researchers in China has found a way to bring dead lithium-ion (锂) batteries back to life, potentially reducing both the amount of waste that’s quickly piling up from spent electric vehicle (EV) batteries and the need to produce as many new ones.
The amount of spent lithium-ion batteries that need to deal with is expected to rise sharply from an estimate of 900,000 metric tons this year to 20.5 million metric tons by 2040, according to a report released by the United Nations Development Program last September. So Gao, a chemist at Fudan University in Shanghai and his colleagues wanted to find a molecule (分子) that could refill a dead cell by adding it with lithium ions.
The researchers used an artificial intelligence model trained on the rules of chemistry. They fed it a database of electrochemical reactions and had it look for molecules that would meet their requirements, such as dissolving well in an electrolyte (电解质) solution and being relatively cheap to produce. The model recommended three candidates, and the team identified one of them, a salt called lithium trifluoromethanesulfinate (LiSO2CF3), as ideal.
Gao and his colleagues found that the chemical mixture could significantly extend the lifetime of a lithium iron phosphate (LFP) battery cell. An LFP battery that powers an EV can typically be charged and then discharged about 2,000 times before it is considered “dead” (when its capacity is below the 80 percent mark). By adding the electrolyte whenever the battery neared that threshold, the team was able to restore most of the cell’s capacity each time — and it carried on working almost as well as a new battery. By the end of the experiment, the cell regained 96 percent capacity after nearly 12,000 charge-discharge cycles.
A follow-up experiment showed the method also worked on NMC (nickel, manganese and cobalt) lithium-ion batteries, Gao says.
Fudan University is currently working with China-based battery-material maker to commercialize the method. Gao imagines a widespread system of “battery-boosting stations” where EV owners will be able to bring dead power sources to be fixed.

(24-25高二下·内蒙古呼和浩特·期末)Have you ever struggled with a task because two arms just weren’t enough? If so, you might like a new device that can really lend a helping hand. You wear this robotic arm, and then control it with the muscle you use to breathe.
Currently, the robotic arm is worn in the middle of your chest, but it can also be placed above your shoulders or at your side, depending on what you want to do with it. Engineer Giulia Dominijanni, part of a team at the Swiss Federal Institute of Technology in Lausanne (École Polytechnique Fédérale de Lausanne, EPFL), helped create the device.
In the past, robotic arms were designed to replace lost arms, with brain signals controlling them. This new device allows users to control an extra arm while still using their real arms. For this reason, the team designed it to be controlled by breathing.
The robotic arm can sense the movement of your diaphragm (膈膜), the muscle that helps you breathe. When you breathe in, the robotic arm stretches; when you breathe out, it retracts (缩回). Breathing normally keeps the arm in the same position.
Before making the actual arm, the EPFL team created a virtual reality (VR) model. Volunteers learned to control this virtual third arm using breath sensors. The tests showed that people could easily look around and talk while using the arm.
After successful VR tests, the team built a simple robotic arm that functions like the virtual one. Early tests showed that users could comfortably operate the extra arm alongside their own arms.
However, researchers are still exploring how well people can control this robotic arm without affecting the use of their natural arms. Jacob George, a director at the University of Utah’s robotics center, notes, “When you’re adding something new on your body, it’s unclear how much the brain can do with that. But in time it becomes possible to control the new arm well.” And scientists at EPFL believe that understanding this could benefit those with disabilities or people recovering from injuries.
1.How do EPFL’s robotic arms differ from previous ones?
A.They feature affordable prices. B.They are operated by breathing.
C.They can deal with our health issues. D.They are controlled by brain signals.
2.Why did the EPFL team create a VR model?
A.To test the newly-invented arm’s actual function. B.To figure out how the robotic arm work.
C.To attract more volunteers. D.To cut its production cost.
3.What is Jacob’s attitude to the robotic arm?
A.Uncaring. B.Doubtful. C.Positive. D.Unclear.
4.Which can be a suitable title for the text?
A.A New Device that Can Really Help Scientists
B.The Effect of Robotic Technology on People’s Life
C.Tips on How to Use an Extra Arm
D.Robotics Gives Us an Extra Arm
(24-25高二下·贵州六盘水·期末)Within the next 3-5 years, advanced humanoid robots will transform elderly care by providing both physical support and emotional companionship. Professor Liu Lizheng of Fudan University emphasizes that robots must achieve high functional intelligence and genuine emotional interaction to make old people feel cared for, not just assisted.
The “Guanghua No.1” robot, developed by Liu’s team, has made it. Standing 165cm tall and weighing 62kg, it walks upright and expresses 21 distinct emotions, including joy, anger, and sorrow, through its animated face. This robot’s ability to understand emotions, which is important for building trust, comes from three years of research that combines body movement science, computer technology, and large data systems. It employs a system inspired by the human brain and a reward method similar to how the brain uses dopamine (多巴胺), allowing it to recognize and react to people’s feelings in a human-like way.
Physically, the robot prioritizes safety and accuracy. Equipped with intelligent joints and a layered body-brain model, it performs delicate tasks like assisting seniors to rise from bed or move to the bathroom. Unlike household robots, caregiver robots assist fragile users. “If collision risks arise, it must carry out protective actions instantly,” Liu stresses. The robot continuously learns household routines through observation, adapting to individual preferences in cooking, cleaning, or mobility support.
Global demand drives this innovation. Countries facing severe aging populations have shown strong interest in Guanghua No.1, which communicates in six languages. China currently leads this field, with multiple teams developing solutions for a shared challenge: sustainable elderly care.
Robots like Guanghua No.1 represent more than technology — they offer tireless, personalized care combining physical assistance and emotional warmth. As the world’s population changes, these new technologies may change how we respect older people by giving all-day help without getting tired.
1.How does Guanghua No.1 express its emotions?
A.Through animated facial expressions.
B.By reacting based on dopamine-like rewards.
C.Through upright walking and body gestures.
D.By using a system inspired by computer technology.
2.Why does the author mention “household robots” in the passage 3?
A.To give an example. B.To make a comparison.
C.To introduce a new topic. D.To provide an explanation.
3.What can be inferred from the passage about the future of elderly care?
A.Elderly people will no longer need human care.
B.Robots will no longer need to learn household routines.
C.Elderly people may receive 24-hour care from robots.
D.Caregiver robots will fully replace household robots soon.
4.From which section of a magazine is this passage most probably taken?
A.Health and Fitness. B.Science and Technology.
C.Culture and History. D.Sports and Entertainment.
(24-25高二下·河南商丘·期末)A fully soft, 3D-printed robot that operates without any electronics has been developed by engineers at the University of California, San Diego. Led by mechanical engineer Yichen Zhai, the team created an insect-inspired robot with six flexible legs that moves completely using air from a container. Remarkably, the entire robot is printed as one single piece from plastic, a process taking about two and a half days.
Unlike conventional robots needing electricity, this innovation relies on air pressure. Because of this design, the robot is waterproof, as demonstrated when it successfully walked through beach shallows during testing.
The six-legged design provides excellent stability on rough surfaces. When moving, three legs step while the other three remain grounded, preventing the robot from tipping over easily. Perla Maiolino, a soft robotics expert at the University of Oxford, finds the design “quite interesting”, highlighting its unique single-material, single-piece construction unlike typical multi-part constructed robots.
This electronics-free approach holds significant promise for future applications. Such robots could potentially work in dangerous environments where electronics fail or pose risks, such as underwater, in mines, or even in space. They represent a step towards free-standing robots usable in tough conditions without power wires.
However, the current model has limitations. Its speed is only about 4 centimeters per second — faster than a snail but slower than a turtle — and it can only operate for 80 seconds on an air container. It also moves only in a straight line and cannot yet turn or avoid barriers. Zhai’s team is actively working on a faster version and aims to develop a turning system, potentially using controlled airflow to move around like a simple self-driving device.
While not yet ready for demanding tasks, Zhai emphasizes the robot’s current accessibility. “The robot is like a toy,” be says. Being cheaply and easily 3D printable means “If people love it, they can make it. That’s enough.”
1.What is a key feature of the robot?
A.It requires complex tools to build. B.It is printed as a single plastic piece.
C.It has electronic sensors for movement. D.It uses multiple materials for flexibility.
2.What is Perla Maiolino’s attitude towards the robot’s design?
A.Doubtful. B.Unconcerned. C.Critical. D.Positive.
3.What aspect of the robot is expected to be improved in future research?
A.Its structural complexity. B.Its ability to avoid barriers.
C.Its data processing capacity. D.Its use of electronic parts.
4.Which of the following is the best title for the text?
A.A 3D-Printed Robot with Four Legs B.The Advantages of Air-Powered Robots
C.The Speed and Limitations of a Soft Robot D.An Air-Powered Robot Without Electronics

(2025·福建泉州·模拟预测)Flying roast chickens, hot coffee, milk, and bread will drop from the air into Queensland backyards in a world-first drone delivery trial expected to start within weeks.
A company called Wing made public its new Australian drone service, extending its reach from an early trial in Canberra, making Australia the first country in the world to use home delivery drones in two areas.
James Ryan Burgess, the company’s CEO, said the drone services were likely to extend into more areas in the future, with the country picked as a testbed for drone services worldwide.
Wing’s latest drone project will see “tens of drones” deliver goods to houses in Queensland. In its Early Flyer program, people would be able to order a number of goods, with drone delivery offered free and within just minutes of placing an order. Its Canberra record for preparing and delivering a coffee stood at just three minutes.
Mr. Burgess said the company chose Queensland’s Logan area because of its growing population and a large number of young families. But he said Wing would take to the skies in other parts of Australia in the future as many Australians wanted to try the technology and safety regulators were open to testing it.
“This will be the most modern drone delivery service in Australia but it’s also the best in the world,” he said. “Australia will always have our most modern drone technology, and we will take what we learn in Australia and use it around the world.”
Wing delivery drones commonly fly at a height of 60m, Mr. Burgess said, could carry up to 1.5kg of goods, and lower packages to areas in front or backyards.
Civil Aviation Safety Authority spokesman Peter Gibson said he hoped the regulator would allow Wing to fly its drones in Logan shortly, as the company had already shown its technology was safe in Canberra trials over the past two years.
1.Why did Wing choose Queensland’s Logan area?
A.There are many backyards there.
B.People are open to drone delivery.
C.An increasing number of young people live there.
D.The population of Logan is larger than that of others.
2.What can we infer about drone delivery service?
A.It is efficient and safe in Logan.
B.The weight of delivered goods is limited.
C.Wing has extended the service into many areas.
D.It is the most modern drone delivery service in the world.
3.What do Peter Gibson’s words in the last paragraph show?
A.His expectation. B.His prediction. C.His Humor. D.His concern.
4.What is the best title for the text?
A.The Early Trial of Drone Delivery B.The Development of Drone Delivery
C.Drones are the Future of Food Delivery D.Lunch and Coffee Orders can Fly in the Sky
(2025·江西新余·模拟预测)Scientists from UNSW Sydney have developed a groundbreaking method to tackle the common problem of “forever chemicals” in water. These chemicals, known scientifically as polyfluoroalkyl substances (PFAS), are difficult to break down, causing significant environmental and health risks. The new method involves a novel catalyst (催化剂) system that promises a more efficient and sustainable solution, for breaking down these compounds.
PFAS are widely used in various industries due to their resistance to heat, water, and oil. They’re found in products such as cookware, food packaging and clothing. Their widespread use has led to global pollution of water sources and soil. A study has shown that almost half of America tap water is polluted with alarming levels of PFAS, raising concerns about their environmental and health impacts. PFAS are called “forever chemicals” because their stable chemical structure makes them resistant to degradation. That means they persist in the environment and accumulate in the human body, potentially leading to harmful health outcomes.
Current methods to remove PFAS from water such as activated carbon absorption have significant deficiencies. Activated carbon can absorb PFAS but requires burning to destroy the chemicals, which is environmentally harmful. Oxidizing agents can break down PFAS into smaller, more persistent structures, complicating the removal process. These methods are inefficient and not environmentally friendly, highlighting the need for better solutions.
The catalyst system developed by Dr. Jun Sun can break the strong carbon-fluoride (强碳氟键) bonds in PFAS, using nano zero-valent metals (纳米零价金属) combined with a catalyst inspired by the structure of vitamin B12. The system was tested on common PFAS compounds like branched PFOS, showing impressive results.
Dr. Sun explained, “The new system we’ve developed shows successful PFAS measures to solve water pollution in the lab, which we hope to eventually test at larger scales.” Within five hours, the new method achieved a 7% breakdown of PFAS, significantly outperforming existing B12-based catalysts, which managed less than 8% breakdown in the same period.
While further research is needed before the method can be applied on a large scale, the team is optimistic. They plan to conduct more tests and explore integrating the catalyst into electro-chemical cells for broader application.
1.What do we know about PFAS?
A.They are common chemicals.
B.They are harmless compounds.
C.They are widely used in agriculture.
D.They damage the earth in many aspects.
2.Which of the following can replace the underlined word “deficiencies” in Paragraph 3?
A.Strength. B.Shortcoming. C.Difference. D.Diversity.
3.What is the team’s plan for the future of the new method?
A.To find other substitutes of PFAS.
B.To apply it on a large scale immediately.
C.To test it more before putting it to use widely.
D.To develop new chemicals having similar features.
4.What is the main point of the passage?
A.“ Forever chemicals” in water can be broken down.
B.A catalyst system is saving human from disasters.
C.Polluted water will be safe to drink in the future.
D.PFAS can be used in more industries in future.

(24-25高二下·黑龙江大庆·期末)For over 1,800 years, doctors have used silk to sew wounds. Now, biomedical engineers are using it to make different types of medical implants (植入物).
Doctors like silk for a variety of reasons. First, silk is a natural material that will break down in the body over time. So any implanted parts made of silk don’t have to be removed by surgery. Plus, not many people are sensitive to it.
The materials currently used to make silk parts are made of proteins called silk fibroin. They are typically dissolved (溶解) in water until needed. But like all proteins, silk proteins can break down over time. Besides, all that water adds a lot of weight and volume to the silk materials as they’re stored, which makes those materials expensive to ship from place to place.
David Kaplan from Tutts University and his colleagues set out to solve those problems. First, they put the silk proteins into salt. Next, they added water to the mixture. They then added a chemical called liquid nitrogen. Afterward, they put the icy mix into a place where the air pressure was very low. That combination of very low temperature and pressure caused water to disappear. Finally, the researchers turned the freeze-dried material into a powder.
Powdered silk could help make really strong medical implants (such as the tools used to hold a broken bone together), which is a great breakthrough in the medical field. Besides, being biocompatible (生物相容的) is just the icing on the cake. It enables powdered silk to have another possible use: putting drugs into the implants. The implants could slowly release a drug over time. That way, patients might not need to take pills or get painful injections.
Powdered silk is easy to work with, too. It is chemically stable and can last up to two years on the shelf. Plus, it’s lightweight because a lot of the water has been removed. So it doesn’t cost as much to ship the material.
1.Why do doctors like silk?
A.Its long history. B.Its rich variety. C.Its affordable price. D.Its outstanding nature.
2.What function does liquid nitrogen serve in David’s research?
A.To separate salt from the mixture. B.To produce low temperature.
C.To keep the low pressure. D.To make a mixture.
3.What does the underlined part “the icing on the cake” in paragraph 5 mean?
A.A piece of cake. B.Another bonus. C.A coincidence. D.A tendency.

【导语】本文是一篇说明文。文章主要介绍了研究人员如何将丝绸转化为粉末状医疗材料,并详细阐述了这种方法的优势及其潜在应用。
1.细节理解题。根据第二段“Doctors like silk for a variety of reasons. First, silk is a natural material that will break down in the body over time. So any implanted parts made of silk don’t have to be removed by surgery. Plus, not many people are sensitive to it.(医生们喜欢丝绸有很多原因。首先,丝绸是一种天然材料,会随着时间的推移在体内分解。因此,任何用丝绸制成的植入部件都不需要通过手术移除。另外,对它过敏的人不多)”可知,医生喜欢丝绸是因为它是一种天然材料,会随时间在体内分解,不需要手术移除,且很多人对其不过敏,这些都是丝绸的优秀特性。故选D项。
2.细节理解题。根据第四段“Next, they added water to the mixture. They then added a chemical called liquid nitrogen. Afterward, they put the icy mix into a place where the air pressure was very low. That combination of very low temperature and pressure caused water to disappear.(接下来,他们向混合物中加水。然后,他们加入了一种叫做液氮的化学物质。之后,他们把冰冷的混合物放进一个气压很低的地方。极低的温度和压力的组合使水消失了)”可知,液氮的作用是产生极低的温度,以便与低压结合使水消失。故选B项。
3.词句猜测题。根据第五段“Powdered silk could help make really strong medical implants (such as the tools used to hold a broken bone together), which is a great breakthrough in the medical field.

4.主旨大意题。通读全文,结合第一段“For over 1,400 years, doctors have used silk to sew wounds. Now, biomedical engineers are using it to make different types of medical implants (植入物).(1400多年来,医生们一直用丝绸来缝合伤口。现在,生物医学工程师正在用它来制造不同类型的医疗植入物)”以及下文内容可知,本文主要介绍了研究人员如何将丝绸转化为粉末状医疗材料,并详细阐述了这种方法的优势及其潜在应用。故选D项。
(24-25高二下·辽宁大连·期末)Can you imagine a house made from mushrooms? What benefits could such a material offer compared to traditional building materials?
In the development of sustainable construction, Czech researchers and architects have showcased a building made primarily from mycelia (菌丝). The innovative house named Samorost is 3.5-meter-tall and 7-meter-long, using 1,800 kilograms of mycelia. Samorost is designed to serve as both a functional structure and a striking example of how mycelia can be used to replace traditional, fossil-fuel-based materials like polystyrene (聚苯乙烯) for environmental benefits.
The mycelia used in the construction of Samorost are made from the root system of a species of mushroom, known for its durability (耐用性) and strength. Mycelia, when combined with natural, renewable materials such as wood, become a lightweight yet durable building material. Besides, unlike polystyrene, mycelia are biodegradable and produce significantly lower CO₂ emissions during, production. Additionally, mycelia have numerous potential applications in construction, such as being used as structural components like walls. As the material is both fire-resistant and highly customizable, mycelia can be used for furniture or supporting walls.
However, experts caution that while mycelia show promise, their widespread use in construction may take time. According to Katerina Sysova, an architect at the Czech Technical University, mycelia are not yet suited for every application, such as external building materials in multi - story buildings, where wet atmosphere could compromise their performance.
Still, with growing support from the European Union’s sustainability initiatives and increasing demand for environmentally friendly solutions, mycelia - based construction could become the mainstream in the coming years.

(24-25高二下·四川成都·期末)Scientists have discovered a new technique by which light can be bent around corners, inspired by the way clouds scatter (散射) sunlight. This type of light-bending could lead to improvements in many fields such as medical imaging and electronics cooling.
Daniele Faccio at the University of Glasgow, UK, and his workmates say they are shocked that this type of light scattering wasn’t noticed before. It works on the same basis as clouds, snow and other white materials that absorb light: once photons (光子) hit the surface of such a material, they are scattered in all directions.
“The light goes around and tries to get in,” says Faccio. “And eventually what happens is that it just gets reflected back because it can’t get in. This is this scattering.”
To copy this process, the team 3D printed objects from a special white material while leaving thin tunnels (通路) within. When light is shone at the material, it travels into these tunnels and is scattered — just as light is on snow or clouds. However, instead of scattering randomly in every direction, the photons are directed to return to the tunnels by the material. The team put this to use, creating a range of objects that control light in an organised way. The researchers say their material improves light transmission much better than those without the same tunnels, and also allows it to be directed around curves.
This method of light-bending could make use of existing tunnels of some special materials to provide new ways to carry out medical imaging. Faccio says the exact same way also works to direct heat and neutrons, and could therefore also find use in a range of engineering applications such as cooling systems.
1.What inspired the discovery of the technique?
A.How light travels. B.How clouds scatter sunlight.
C.The relevant studies. D.The features of white materials.

(24-25高二下·辽宁·期末)A team of researchers in China has found a way to bring dead lithium-ion (锂) batteries back to life, potentially reducing both the amount of waste that’s quickly piling up from spent electric vehicle (EV) batteries and the need to produce as many new ones.
The amount of spent lithium-ion batteries that need to deal with is expected to rise sharply from an estimate of 900,000 metric tons this year to 20.5 million metric tons by 2040, according to a report released by the United Nations Development Program last September. So Gao, a chemist at Fudan University in Shanghai and his colleagues wanted to find a molecule (分子) that could refill a dead cell by adding it with lithium ions.
The researchers used an artificial intelligence model trained on the rules of chemistry. They fed it a database of electrochemical reactions and had it look for molecules that would meet their requirements, such as dissolving well in an electrolyte (电解质) solution and being relatively cheap to produce. The model recommended three candidates, and the team identified one of them, a salt called lithium trifluoromethanesulfinate (LiSO2CF3), as ideal.
Gao and his colleagues found that the chemical mixture could significantly extend the lifetime of a lithium iron phosphate (LFP) battery cell. An LFP battery that powers an EV can typically be charged and then discharged about 2,000 times before it is considered “dead” (when its capacity is below the 80 percent mark). By adding the electrolyte whenever the battery neared that threshold, the team was able to restore most of the cell’s capacity each time — and it carried on working almost as well as a new battery. By the end of the experiment, the cell regained 96 percent capacity after nearly 12,000 charge-discharge cycles.
A follow-up experiment showed the method also worked on NMC (nickel, manganese and cobalt) lithium-ion batteries, Gao says.
Fudan University is currently working with China-based battery-material maker to commercialize the method. Gao imagines a widespread system of “battery-boosting stations” where EV owners will be able to bring dead power sources to be fixed.

(24-25高二下·内蒙古呼和浩特·期末)Have you ever struggled with a task because two arms just weren’t enough? If so, you might like a new device that can really lend a helping hand. You wear this robotic arm, and then control it with the muscle you use to breathe.
Currently, the robotic arm is worn in the middle of your chest, but it can also be placed above your shoulders or at your side, depending on what you want to do with it. Engineer Giulia Dominijanni, part of a team at the Swiss Federal Institute of Technology in Lausanne (École Polytechnique Fédérale de Lausanne, EPFL), helped create the device.
In the past, robotic arms were designed to replace lost arms, with brain signals controlling them. This new device allows users to control an extra arm while still using their real arms. For this reason, the team designed it to be controlled by breathing.
The robotic arm can sense the movement of your diaphragm (膈膜), the muscle that helps you breathe. When you breathe in, the robotic arm stretches; when you breathe out, it retracts (缩回). Breathing normally keeps the arm in the same position.
Before making the actual arm, the EPFL team created a virtual reality (VR) model. Volunteers learned to control this virtual third arm using breath sensors. The tests showed that people could easily look around and talk while using the arm.
After successful VR tests, the team built a simple robotic arm that functions like the virtual one. Early tests showed that users could comfortably operate the extra arm alongside their own arms.
However, researchers are still exploring how well people can control this robotic arm without affecting the use of their natural arms. Jacob George, a director at the University of Utah’s robotics center, notes, “When you’re adding something new on your body, it’s unclear how much the brain can do with that. But in time it becomes possible to control the new arm well.” And scientists at EPFL believe that understanding this could benefit those with disabilities or people recovering from injuries.
1.How do EPFL’s robotic arms differ from previous ones?
A.They feature affordable prices. B.They are operated by breathing.
C.They can deal with our health issues. D.They are controlled by brain signals.
2.Why did the EPFL team create a VR model?
A.To test the newly-invented arm’s actual function. B.To figure out how the robotic arm work.
C.To attract more volunteers. D.To cut its production cost.
3.What is Jacob’s attitude to the robotic arm?
A.Uncaring. B.Doubtful. C.Positive. D.Unclear.
4.Which can be a suitable title for the text?
A.A New Device that Can Really Help Scientists

(24-25高二下·贵州六盘水·期末)Within the next 3-5 years, advanced humanoid robots will transform elderly care by providing both physical support and emotional companionship. Professor Liu Lizheng of Fudan University emphasizes that robots must achieve high functional intelligence and genuine emotional interaction to make old people feel cared for, not just assisted.
The “Guanghua No.1” robot, developed by Liu’s team, has made it. Standing 165cm tall and weighing 62kg, it walks upright and expresses 21 distinct emotions, including joy, anger, and sorrow, through its animated face. This robot’s ability to understand emotions, which is important for building trust, comes from three years of research that combines body movement science, computer technology, and large data systems. It employs a system inspired by the human brain and a reward method similar to how the brain uses dopamine (多巴胺), allowing it to recognize and react to people’s feelings in a human-like way.
Physically, the robot prioritizes safety and accuracy. Equipped with intelligent joints and a layered body-brain model, it performs delicate tasks like assisting seniors to rise from bed or move to the bathroom. Unlike household robots, caregiver robots assist fragile users. “If collision risks arise, it must carry out protective actions instantly,” Liu stresses. The robot continuously learns household routines through observation, adapting to individual preferences in cooking, cleaning, or mobility support.
Global demand drives this innovation. Countries facing severe aging populations have shown strong interest in Guanghua No.1, which communicates in six languages. China currently leads this field, with multiple teams developing solutions for a shared challenge: sustainable elderly care.
Robots like Guanghua No.1 represent more than technology — they offer tireless, personalized care combining physical assistance and emotional warmth. As the world’s population changes, these new technologies may change how we respect older people by giving all-day help without getting tired.
1.How does Guanghua No.1 express its emotions?
A.Through animated facial expressions.
B.By reacting based on dopamine-like rewards.
C.Through upright walking and body gestures.
D.By using a system inspired by computer technology.
2.Why does the author mention “household robots” in the passage 3?
A.To give an example. B.To make a comparison.
C.To introduce a new topic. D.To provide an explanation.
3.What can be inferred from the passage about the future of elderly care?
A.Elderly people will no longer need human care.
B.Robots will no longer need to learn household routines.
C.Elderly people may receive 24-hour care from robots.
D.Caregiver robots will fully replace household robots soon.
4.From which section of a magazine is this passage most probably taken?

(24-25高二下·河南商丘·期末)A fully soft, 3D-printed robot that operates without any electronics has been developed by engineers at the University of California, San Diego. Led by mechanical engineer Yichen Zhai, the team created an insect-inspired robot with six flexible legs that moves completely using air from a container. Remarkably, the entire robot is printed as one single piece from plastic, a process taking about two and a half days.
Unlike conventional robots needing electricity, this innovation relies on air pressure. Because of this design, the robot is waterproof, as demonstrated when it successfully walked through beach shallows during testing.
The six-legged design provides excellent stability on rough surfaces. When moving, three legs step while the other three remain grounded, preventing the robot from tipping over easily. Perla Maiolino, a soft robotics expert at the University of Oxford, finds the design “quite interesting”, highlighting its unique single-material, single-piece construction unlike typical multi-part constructed robots.
This electronics-free approach holds significant promise for future applications. Such robots could potentially work in dangerous environments where electronics fail or pose risks, such as underwater, in mines, or even in space. They represent a step towards free-standing robots usable in tough conditions without power wires.
However, the current model has limitations. Its speed is only about 4 centimeters per second — faster than a snail but slower than a turtle — and it can only operate for 80 seconds on an air container. It also moves only in a straight line and cannot yet turn or avoid barriers. Zhai’s team is actively working on a faster version and aims to develop a turning system, potentially using controlled airflow to move around like a simple self-driving device.
While not yet ready for demanding tasks, Zhai emphasizes the robot’s current accessibility. “The robot is like a toy,” be says. Being cheaply and easily 3D printable means “If people love it, they can make it. That’s enough.”
1.What is a key feature of the robot?
A.It requires complex tools to build. B.It is printed as a single plastic piece.
C.It has electronic sensors for movement. D.It uses multiple materials for flexibility.
2.What is Perla Maiolino’s attitude towards the robot’s design?

重难语篇提升练
(2025·福建泉州·模拟预测)Flying roast chickens, hot coffee, milk, and bread will drop from the air into Queensland backyards in a world-first drone delivery trial expected to start within weeks.
A company called Wing made public its new Australian drone service, extending its reach from an early trial in Canberra, making Australia the first country in the world to use home delivery drones in two areas.
James Ryan Burgess, the company’s CEO, said the drone services were likely to extend into more areas in the future, with the country picked as a testbed for drone services worldwide.
Wing’s latest drone project will see “tens of drones” deliver goods to houses in Queensland. In its Early Flyer program, people would be able to order a number of goods, with drone delivery offered free and within just minutes of placing an order. Its Canberra record for preparing and delivering a coffee stood at just three minutes.
Mr. Burgess said the company chose Queensland’s Logan area because of its growing population and a large number of young families. But he said Wing would take to the skies in other parts of Australia in the future as many Australians wanted to try the technology and safety regulators were open to testing it.
“This will be the most modern drone delivery service in Australia but it’s also the best in the world,” he said. “Australia will always have our most modern drone technology, and we will take what we learn in Australia and use it around the world.”
Wing delivery drones commonly fly at a height of 60m, Mr. Burgess said, could carry up to 1.5kg of goods, and lower packages to areas in front or backyards.
Civil Aviation Safety Authority spokesman Peter Gibson said he hoped the regulator would allow Wing to fly its drones in Logan shortly, as the company had already shown its technology was safe in Canberra trials over the past two years.
1.Why did Wing choose Queensland’s Logan area?
A.There are many backyards there.
B.People are open to drone delivery.
C.An increasing number of young people live there.
D.The population of Logan is larger than that of others.
2.What can we infer about drone delivery service?
A.It is efficient and safe in Logan.
B.The weight of delivered goods is limited.
C.Wing has extended the service into many areas.
D.It is the most modern drone delivery service in the world.
3.What do Peter Gibson’s words in the last paragraph show?
A.His expectation. B.His prediction. C.His Humor. D.His concern.
4.What is the best title for the text?
A.The Early Trial of Drone Delivery B.The Development of Drone Delivery
C.Drones are the Future of Food Delivery D.Lunch and Coffee Orders can Fly in the Sky
【答案】1.C 2.B 3.A 4.D

4.主旨大意题。根据第一段“Flying roast chickens, hot coffee, milk, and bread will drop from the air into Queensland backyards in a world-first drone delivery trial expected to start within weeks.(在未来几周内即将开展的一项全球首创的无人机送货试验中,烤鸡、热咖啡、牛奶和面包将从空中降落在昆士兰州的居民后院)”结合文章主要说明了Wing公司将在澳大利亚昆士兰州开展全球首个无人机配送试验,配送食品等,可知D选项“午餐和咖啡订单能够‘飞’上天空”最符合文章标题。故选D。
(2025·江西新余·模拟预测)Scientists from UNSW Sydney have developed a groundbreaking method to tackle the common problem of “forever chemicals” in water. These chemicals, known scientifically as polyfluoroalkyl substances (PFAS), are difficult to break down, causing significant environmental and health risks. The new method involves a novel catalyst (催化剂) system that promises a more efficient and sustainable solution, for breaking down these compounds.
PFAS are widely used in various industries due to their resistance to heat, water, and oil. They’re found in products such as cookware, food packaging and clothing. Their widespread use has led to global pollution of water sources and soil. A study has shown that almost half of America tap water is polluted with alarming levels of PFAS, raising concerns about their environmental and health impacts. PFAS are called “forever chemicals” because their stable chemical structure makes them resistant to degradation. That means they persist in the environment and accumulate in the human body, potentially leading to harmful health outcomes.
Current methods to remove PFAS from water such as activated carbon absorption have significant deficiencies. Activated carbon can absorb PFAS but requires burning to destroy the chemicals, which is environmentally harmful. Oxidizing agents can break down PFAS into smaller, more persistent structures, complicating the removal process. These methods are inefficient and not environmentally friendly, highlighting the need for better solutions.
The catalyst system developed by Dr. Jun Sun can break the strong carbon-fluoride (强碳氟键) bonds in PFAS, using nano zero-valent metals (纳米零价金属) combined with a catalyst inspired by the structure of vitamin B12. The system was tested on common PFAS compounds like branched PFOS, showing impressive results.
Dr. Sun explained, “The new system we’ve developed shows successful PFAS measures to solve water pollution in the lab, which we hope to eventually test at larger scales.” Within five hours, the new method achieved a 7% breakdown of PFAS, significantly outperforming existing B12-based catalysts, which managed less than 8% breakdown in the same period.
While further research is needed before the method can be applied on a large scale, the team is optimistic. They plan to conduct more tests and explore integrating the catalyst into electro-chemical cells for broader application.
1.What do we know about PFAS?
A.They are common chemicals.
B.They are harmless compounds.
C.They are widely used in agriculture.
D.They damage the earth in many aspects.
2.Which of the following can replace the underlined word “deficiencies” in Paragraph 3?
A.Strength. B.Shortcoming. C.Difference. D.Diversity.
3.What is the team’s plan for the future of the new method?
A.To find other substitutes of PFAS.
B.To apply it on a large scale immediately.
C.To test it more before putting it to use widely.
D.To develop new chemicals having similar features.
4.What is the main point of the passage?
A.“ Forever chemicals” in water can be broken down.
B.A catalyst system is saving human from disasters.
C.Polluted water will be safe to drink in the future.
D.PFAS can be used in more industries in future.
