37-year-old Casey Ryan felt very comfortable in the mountains of the Willamette National Forest in Eugene, Oregon. He knew its roads and hiking trails well from his time as a volunteer in a roadside clean-up crew. These days, he was often there photographing wildlife, and he almost always had his lightweight drone(无人机) with him. It was one of his favorite cameras.
Though weather conditions weren’t great that morning, Ryan decided to go on a short hike with his friend. Snow was common and Ryan felt he knew the area well enough. Still, as they drove along, the roads became icy. Ryan thought he might turn back, but after a truck passed them coming from the opposite direction, he felt safe enough to keep going. The roads must still be passable in that direction, he reasoned.
But it wasn’t long before the two men came across a woman who was stranded(滞留) along the mountain road. Ryan and his friend stopped to help her. Ryan tried to line up his truck’s rope to pull the woman’s car out —and ended up stuck in the same place.
The three tried for hours to dig the cars out, but the sun was setting fast. The temperature was dropping and the snow was turning to ice blocks around the tires. It was impossible to dig out.
Thirty miles from the closest town, their phones had no signal in such a low-lying(低洼的)area. Their car radio and walkie-talkies couldn’t transmit any signal far enough. The three travelers prepared to spend the night in their cars. The hikers had survival gear(装备) and food to share, so they weren’t terribly worried.
It was Ryan’s friend who, jokingly perhaps, brought up a news report he had seen about a man using a drone to send roses to his girlfriend living on the 10th floor to make a proposal (求婚).

5 . Fly on a lamp on a summer evening and, within minutes, insects will begin to gather near the lamp. This behavior has given rise to a popular simile (比喻) that describes attraction: “like a moth (蛾) to a flame.” Though insects have been “drawn” toward bright light sources for a long time, scientists never truly understood why. Now, they may finally have an answer.
Insects aren’t attracted to artificial lights, according to a new paper published Tuesday in the journal Nature Communications. Rather, the glow (光) might be interfering with their natural sense of direction. The insects you see circling street lights, in other words, are likely lost.
The new finding depends on a theory about navigation. When insects fly, they can experience whole body acceleration up to five times greater than the acceleration caused by gravity. As such, it can be difficult for them to know which way is up and which way is down as they fly through the air.
The study authors suspect insects rely on the glow coming from stars, planets and the moon to reorient (定方向) themselves. For most of Earth’s history, the sky was the brightest source of light at night, so flying insects turned their bodies to make their backs face skyward. But then, artificial light entered the picture.
To reach these conclusions, scientists used high-resolution cameras to film insects flying around artificial lights in Costa Rica. They also attached tiny sensors to dragonflies and moths, then filmed motion-capture videos of them in flight. Together, these methods allowed researchers to slow down the insects’ normally fast pace and study their movements in greater detail. The footage showed insects turning their backs toward sources of artificial light — even at the price of crashing.
If the light’s above them, they might start orbiting it. When they fly directly over a light, they fly themselves upside down and that can lead to crashes. It really suggests that the moth is confused as to which way is up. After running some experiments, researchers determined that light shining straight down provided the least disruption to insects’ flight. Lights that pointed straight up, on the other hand, caused the most difficulties.

6 . Every year, about 15 billion trees are cut down to make way for agriculture, mining, logging. and urban expansion. Such mass deforestation has accelerated global warming and endangered the survival of millions of species. Though many nations, organizations, and even individuals have tried, no one could plant enough trees to make up for that loss — but some innovative entrepreneurs are working on a high-tech solution.
BioCarbon Engineering (BCE), a U.K.-based start-up, has developed a technique that could plant one billion trees per year. The method? Drones (无人机). Current tree-planting programs "are just not fast enough," said Irina Fedorenko, a co-founder of the company. "But our technology is automated, so we can scale up quite realistically and quite quickly."
First, a drone scans the land and develops a 3-D map of the area. Then, using the data from this "smart map", the team develops an algorithm (算法) for a unique planting pattern. A drone uses the algorithm to carry out the planting strategy. The drone flies about six feet above the ground, firing growing seeds at a speed that will get them under the soil. The species planted by drone has a better survival rate than helicopter spreading that's more commonly used. Some species even have survival rates nearly identical to hand planting.
With GPS and imaging technologies, experts agree that drones have become useful for accurately mapping large areas of land and measuring tree growth. But some scientists are more skeptical about their success as a planting technology to tackle deforestation on a large scale. After all, they only have so much range and battery life.
"Drones are good for measuring secondary growth and looking at where the forest is coming back, but you fight deforestation at a socioeconomic level," says Arturo Sanchez, director of the University of Alberta's Center for Earth Observation and Sciences. "The issue of climate change is not forest restoration, the issue is energy. It is controlling coal plants, power plants, automobile emissions. Planting trees is very important, but when you look at the distribution of CO₂ emissions, deforestation accounts for 10 to 15 percent. The rest is energy. That's what needs to be controlled."

7 . In a heartwarming display of community spirit, six student lacrosse (长曲棍球) players from Roslyn High School in New York have come together to make sports more accessible for people with disabilities. The initiative, dubbed" Lacrosse My Heart," was started by a group of teenagers who were inspired to create a more inclusive environment for their peers with disabilities.
The program focuses on adapting lacrosse, a popular sport in the area, to meet the needs of individuals with physical and cognitive disabilities. The students have designed specialized equipment and rules to ensure that everyone can participate, regardless of their abilities. For example, they have created larger goals and lighter balls to make scoring easier, and have implemented modifications such as allowing players to use their hands to catch and throw the ball. These adaptations have made the sport more accessible and enjoyable for all participants.
The program has gained significant support from the local community, with many schools and organizations donating resources and volunteering their time. The students have also received guidance from experts in adapted physical education, ensuring that the program is safe and enjoyable for all participants. This collaboration has helped to create a program that is both inclusive and beneficial for everyone involved.
One of the key aspects of Lacrosse My Heart is its emphasis on building relationships between able-bodied students and those with disabilities. The founders wanted to create an environment where kids with disabilities could feel included and build friendships with their peers. This approach has been successful, with participants reporting increased confidence and social skills.
Lacrosse My Heart is not only providing opportunities for individuals with disabilities to participate in sports but also promoting understanding and acceptance among young people. By creating a welcoming environment and adapting sports to meet individual needs, these high school students are breaking down barriers and fostering a sense of community that goes beyond the playing field. Their efforts are not only changing lives but also inspiring others to create more inclusive spaces for individuals with disabilities.

9 . Even minor changes in behavior can have a positive environmental impact. Therefore, it is suggested to remove or reduce single-use plastic bags from your shopping trips, because the bags break down slowly, causing them to linger in landfills. But how long does a plastic bag really stick around?
The Center for Biological Diversity estimates that it takes a bag roughly 1000 years to break down. The term “break down” is a little misleading, though. Plastic ends up photodegrading (光降解) from ultraviolet (紫外线) radiation because the majority of microorganisms cannot eat it. And even after the bags degrade, the micro-plastics they leave behind may still harm the environment.
While 1000 years seems long, it is only an estimate. Since the invention of plastic bags in the 1950s or so, humankind has never actually seen the substance break down in real time. Instead, scientists have adopted respirometry tests (呼吸运动测量法), which helps estimate the breakdown rate of an organic substance by measuring the CO2 that the microorganisms produce when breaking down the material. When an organic substance, such as food waste, is present, CO2 levels rise, which allows scientists to estimate the rate of breakdown. However, because plastic bags don’t produce any CO2,—microorganisms aren’t eating them, the bags are just sitting there. If buried in a landfill and sheltered from ultraviolet light, plastic bags will last a very long time.
Bags have an impact on the environment beyond just their removal. It takes fossil fuels to make bags; one estimate puts this amount at 12 million barrels (桶) of oil annually. And after a bag has served its purpose in a consumer’s hands, it may then enter the food chain for wildlife. Plastic that builds up along the food chain is consumed by creatures like birds and fish.
While reducing the use of plastic bags is a good idea, choosing a cloth bag might not be the habit that will help the environment the most. The carbon footprint left by the cloth bags must be countered by thousands of uses.

10 . Joyce Loaiza lives alone, but when returning to her apartment at a senior community, she often has a chat with a friendly female voice. The 81-year-old is among the first in the United States to receive the robot ElliQ made by Intuition Robotics, which has been the only device using artificial intelligence specifically designed to address loneliness of the old.
Looking like a small table light, the device has an eyeless, mouthless head. It remembers each user’s interests and their talks, helping create a special experience with each new discussion, which can be as deep as the meaning of life or as light as a small joke. “She’ll make comments like, ‘I would go outside if I had hands, but I can’t hold an umbrella,’” said Loaiza. ElliQ also plays music and provides spiritual sayings. It leads exercises, asks about the owner’s health, and gives reminders to take medicines and drink water. It can also support video calls and contact family, friends, or doctors in an emergency.
The average user interacts with ElliQ more than 30 times a day and more than 90 percent report lower levels of loneliness, Intuition Robotics CEO Dor Skuler said.
Brigham Young University professor Julianne Holt-Lunstad, who studies the effects of loneliness on health, worries that a device like ElliQ might have short-term helpful effects but it could make people less likely to seek human contact. She noted that the difficult feeling of loneliness should push people to reconnect socially.
Skuler and state officials agreed that ElliQ is not an alternative to human contact. But some older people cannot leave home or do not have many friends. Charlotte Taylor, director of an Area Agency on Aging, said Covid-19 left many older people more disconnected. Her agency has provided 300 ElliQs which, she believes, help the situation. She said, “People generally like her and she makes them smile.”
1. What can we infer from Loaiza’s comments on ElliQ?| A．It sometimes fails to be of any help. | B．It is humorous and has the human touch. |
| C．Some of its comments make no sense. | D．It shows an interest in the outside world. |
| A．Its inefficiency to ease loneliness. | B．Its failure to push people to reconnect. |
| C．Its potential for being addictive. | D．Its replacement for human interactions. |
| A．Novel. | B．Popular. | C．Satisfying. | D．Advanced. |
| A．Chatty Robot Helps Seniors Fight Loneliness | B．AI-based Device Is to Dominate Elders’ Life |
| C．ElliQ: a Revolutionary Innovation in AI Field | D．ElliQ: a Remarkable Assistant after Covid-19 |
