1 . A new study reveals that pigeons (鸽子) can tackle some problems just like artificial intelligence, enabling them to solve difficult tasks that might challenge humans. Previous research has theorized that pigeons employ a problem-solving strategy, involving a trial-and- error approach, which is similar to the approach used in AI models but differs from humans’ reliance on selective attention and rule use. To examine it, Brandon Turner, a psychology professor at the Ohio State University, and his colleagues conducted the new study.
In the study, the pigeons were presented with various visual images, including lines of different widths and angles, and different types of rings. The pigeons had to peck (啄) a button on the right or left to indicate the category to which the image belonged. If they got it correct, they received food; if they were wrong, they received nothing. Results showed that, through trial and error, the pigeons improved their accuracy in categorization tasks, increasing their correct choices from about 55% to 95%.
Researchers believed pigeons used associative learning, which is linking two phenomena with each other. For example, it is easy to understand the link. between “water” and “wet”. “Associative learning is frequently assumed to be far too primitive to. explain complex visual categorization like what we saw the pigeons do,” Turner said. But that’s exactly what the researchers found.
The researchers’ AI model tackled the same tasks using just the two simple mechanisms that pigeons were assumed to use: associative learning and error correction. And, like the pigeons, the AI model learned to make the right predictions to significantly increase the number of correct answers. For humans, the challenge when given tasks like those given to pigeons is that they would try to come up with rules that could make the task easier. But in this case, there were no rules, which upsets humans.
What’s interesting, though, is that pigeons use this method of learning that is very similar to AI designed by humans, Turner said. “We celebrate how smart we are that we designed artificial intelligence: at the same time, we regard pigeons as not clever animals,” he said.

4 . The environmental practices of big businesses are shaped by a fundamental fact that offends our sense of justice. A business may maximize the amount of money it makes by damaging the environment and hurting people. When government regulation is effective, and the public is environmentally aware, environmentally clean big businesses may out-compete dirty ones, but the reverse is likely to be true if government regulation is ineffective and the public doesn’t care.
It is easy to blame a business for helping itself by hurting other people. But blaming alone is unlikely to produce change. It ignores the fact that businesses are not charities but profit-making companies, and they are under obligation to maximize profits for shareholders by legal means.
Our blaming of businesses also ignores the ultimate responsibility of the public for creating the conditions that let a business profit through destructive environmental policies. In the long run, it is the public, either directly or through its politicians, that has the power to make such destructive policies unprofitable and illegal, and to make sustainable environmental policies profitable.
The public can do that by accusing businesses of harming them. The public may also make their opinion felt by choosing to buy sustainably harvested products; by preferring their governments to award valuable contracts to businesses with a good environmental track record; and by pressing their governments to pass and enforce laws and regulations requiring good environmental practices.
In turn, big businesses can exert powerful pressure on any suppliers that might ignore public or government pressure. For instance, after the US public became concerned about the spread of a disease, transmitted to humans through infected meat, the US government introduced rules demanding that the meat industry abandon practices associated with the risk of the disease spreading. But the meat packers refused to follow these, claiming that they would be too expensive to obey. However, when a fast-food company made the same demands after customer purchases of its hamburgers dropped, the meat industry followed immediately. The public’s task is therefore to identify which links in the supply chain are sensitive to public pressure.
Some readers may be disappointed or outraged that I place the ultimate responsibility for business practices harming the public on the public itself. I also believe that the public must accept the necessity for higher prices for products to cover the added costs of sound environmental practices. My views may seem to ignore the belief that businesses should act in accordance with moral principles even if this leads to a reduction in their profits. But I think we have to recognize that, throughout human history, government regulation has arisen precisely because it was found that not only did moral principles need to be made explicit, they also needed to be enforced.
My conclusion is not a moralistic one about who is right or wrong, admirable or selfish. I believe that changes in public attitudes are essential for changes in businesses’ environmental practices.

5 . Have you noticed how evenings cool off more in rural areas than they do in cities? Urban areas also tend to get hotter during the day than any nearby areas with lots of greenery.
It’s mainly caused by the difference in materials that cover the ground in urban areas and the countryside. In the country, evaporation(蒸发)of water from soil and the leaves of plants helps to cool the air.
Dark colours are another problem. Dark objects absorb all wavelengths of light, making the temperature increase more noticeably. In contrast, white objects reflect all wavelengths of light energy.
But cities don’t have to be so hot. Some cities have lightened their streets. This is done by covering black asphalt streets, parking lots, and dark roofs with a more reflective gray coating.
Having more green spaces also helps. Plants serve as a natural air conditioner. They catch heat, release vapour(蒸汽)into the air, and take away heat, contributing to cooler, fresher cities.
| A．Cities also produce more heat than suburban areas. |
| B．The higher the temperature, the shorter the wavelength. |
| C．This phenomenon is known as the urban heat-island effect. |
| D．So it will not be transformed into heat which makes the air hot. |
| E．Changes in building materials have a minimal effect on city temperatures. |
| F．Much of the soil in cities, by contrast, has been covered with roads and buildings. |
| G．These changes can decrease air temperatures dramatically, especially in summer. |

Sam was a junior high school student. He lived in a community in Charlotte and usually had little exposure to country life. So much of what he knew about plants came from text-books. Sam was a kind-hearted person. He longed for a chance to explore nature and he wanted to do his part to beautify the world.
Finally, the opportunity came. On Arbor Day (植树节), his class organized a trip to a local village to plant trees. Sam was excited about it and couldn’t wait to tell his mom the good news. So the next day, Sam and his mom went to buy some tools for planting trees, including a shovel(铲), a bucket, gloves and so on.
On the day of the event, Sam and his classmates arrived early at the starting point. It was a beautiful day and everyone looked particularly happy. With the tools in hand, Sam got into the bus with everyone else and headed off to their destination.
As soon as they reached the village, all the students were divided into three teams by their teacher. One team was responsible for planting the trees, one team for shovelling the soil and one team for watering the trees. At the teacher’s command, everyone started to do their job.
However, it was the first time that many of the students had taken part in planting trees, so they had no idea about how to start. Of course, Sam was one of them. Fortunately, their teacher was a middle-aged man from the countryside who had some knowledge of planting trees. In order to set an example to the students, the teacher started to plant trees himself. After watching the teacher plant the trees, everyone also became busy. Before long, they planted hundreds of trees. Sam watched very carefully, not wanting to miss any of the details. Finally, Sam learned how to plant trees by himself and felt happy.

9 . Beavers(海狸), like humans, change their surroundings to fit their needs. Known as nature’s engineers, they tear trees down to build homes to live in and dams to raise water levels for protection from enemies. Dams also slow water’s flow while blocking sediment(沉积物)that would otherwise flow downstream. The resulting wetlands often attract wildlife diversity where none had existed. There are challenges, though. Beaver dams sometimes cause flooding, and most people prefer trees alive and upright.
Communities face a delicate balancing act, learning to coexist with beavers. Last winter, many people enjoying Winston Path became beaver fans as one furry family transformed Swallow Pond into an oasis for birds, frogs, turtles and deer.
Yet such activity caused concern. As beavers worked, they raised water levels about five feet. The increased depth allows beavers to survive underwater if the pond ices over. But county officials were concerned about how higher water would affect the soil bank supporting Winston Path.
To find a good balance between protecting the path and the beavers, the county introduced a“ beaver baffle”— a pond leveler.Beavers often rush to fill holes in their dams.Baffles stabilize water levels by creating a hidden exit for high water to escape through the dam, unnoticed by the beavers.
People love the beavers but they also love the mature trees. Recently, Catherine Jones,18, organized a tree-caging event — putting wire cloth around large tree trunks to discourage beavers from biting them. It also protects people from injury due to random trees falling.“We cover the trees we don’t want them to eat, while planting periodically others they like,“said Jones.“We need-to learn to give up a little of our wants to share the Earth’s resources.”
Swallow Pond’s 2023 project will restore proper water depth and improve wildlife habitat without creating problems for the path. The balancing act continues.

10 . The number of weather-related disasters has increased by five times over the past 50 years, the latest report by the World Meteorological (气象) Organization (WMO) said on September. However, thanks to improved early warning systems and disaster management, the number of death from these hazards (危险) has been almost three times less.
According to the WMO, from 1970 to 2019, weather, climate and water hazards accounted for 50 percent of all disasters. Among the top 10 hazards that led to the largest loss of human life during this period were droughts, storms, floods and extreme temperatures. However, deaths fell from over 50, 000 in the 1970s to less than 20, 000 in the 2010s.
“Weather, climate and water extremes are increasing and will become more frequent and severe in many parts of the world as a result of climate change,” says WMO Secretary-General Petteri Taalas.
“That means more heat waves, drought and forest fires such as those we have observed recently in Europe and North America. We have more water vapor in the atmosphere, which is worsening extreme rainfall and deadly flooding. The warming of the oceans has affected the frequency and area of existence of the most intense tropical storms.”
“Economic losses are increasing as exposure increases. But behind the statistics lies a message of hope. Improved multi-hazard early warning systems have led to a significant reduction in deaths. Quite simply, we are better than ever before at saving lives,” Taalas said.
