1 . In shallow coastal waters of the Indian ocean, Dugong, a kind of sea cow, is in trouble. Environmental problems pose such a major threat to its survival that the International Union for Conservation of Nature (IUCN) upgraded the species’ extinction risk status(地位)to vulnerable (脆弱的).
Much worse, Dugongs are at risk of losing the protection of the Torres Strait Islanders, who have looked after them historically, hunting them for food sustainably and monitoring their numbers. These native people keep their biodiversity, and have deep knowledge about their environment. But these people are also threatened, in part because rising sea levels are making it difficult for them to live there.
This situation isn’t unique to Dugongs. A global analysis of 385 culturally important plant and animal species found 68 percent were both biologically vulnerable and at risk of losing their cultural protection.
The findings clearly illustrate that biology shouldn’t be the primary factor in shaping conservation policy,says anthropologist Victoria Reyes-García.When a culture declines,the species that are important to that culture are also threatened.“Lots of conservationists think we need to separate people from nature,” says Reyes-García. “But that strategy misses the caring relationship many cultural groups have with nature.”
One way to help shift conservation efforts is to give species a “bio-cultural status,”which would provide a fuller picture of their vulnerability. In the study, the team used a new way to determine a species’ risk of disappearing: the more a cultural group’s language use declines, the more that culture is threatened.The more a culture is threatened, the more culturally vulnerable its important species are. Researchers then combined a species’ cultural and biological vulnerability to arrive at its bio-cultural status. In the Dugong’s case, its bio-cultural status is endangered, meaning it is more at risk than its IUCN categorization suggests.
This new approach to conservation involves people that have historically cared for them. It can highlight when communities need support to continue their care. Scientists hope it will bring more efforts that recognize local communities’ rights and encourage their participation-taking advantage of humans’ connection with nature instead of creating more separation.

2 . With an abundance of sun and wind, Spain is positioning itself as Europe’s future leader in green hydrogen production to clean up heavy industries. But some energy experts express caution because this process relies on massive availability of zero-carbon electricity.
Green hydrogen is created when renewable energy sources power an electrical current that runs through water, separating its hydrogen and oxygen molecules (分子). The process doesn’t produce planet-warming carbon dioxide, but less than 0.1% of global hydrogen production is currently created in this way.
The separated hydrogen can be used in the production of steel, ammonia (氨) and chemical products, all of which require industrial processes that are harder to stop fossil fuels. Hydrogen also can be used as a transportation fuel, which could one day transform the highly polluting shipping and aviation sectors.
Spain’s large, windswept and thinly populated territory receives more than 2,500 hours of sunshine on average per year, providing ideal conditions for wind and solar energy, and therefore green hydrogen production.
“If you look at where hydrogen is going to be produced in Europe in the next million years, it’s in two countries, Spain and Portugal,” said Thierry Lepercq, the founder and president of HyDeal Ambition, an industry platform bringing together 30 companies. “Hydrogen is the new oil.”
Lepercq is working with companies like Spanish gas pipeline corporation Enagas and global steel giant ArcelorMittal to design an end-to-end model for hydrogen production, distribution and supply at a competitive price. Criticism has centered on green hydrogen’s higher cost compared with highly-polluting “gray hydrogen” drawn from natural gas. Lepercq argues that solar energy produced in Spain is priced low enough to compete.
Globally, Lepercq said, “Electricity is 20% of energy consumption. What about the 80% that is not electrified? ... You need to replace those fossil fuels. Not in 50 years’ time. You need to replace them now.”

3 . Not every architectural landmark is grand in scale, with splendid decorations, or amazing colors. Suzhou Gardens may just be the opposite.
When a group of monks during the Yuan Dynasty (1271-1368) first constructed Lion Grove Garden, they may have just wanted to enjoy a quiet place, hidden away from urban noise, while in the following centuries, this charming garden - most notable for its waterside rockeries resembling the shape of lions—has attracted a constant stream of celebrity guests, who have left a long list of poems, paintings and historical anecdotes (轶事).
In recent years, nine of the best-known classical gardens of Suzhou, including Lion Grove Garden, Humble Administrator’s Garden and Great Wave Pavilion, were registered into the World Heritage List. As UNESCO remarks, “Classical Chinese garden design, which seeks to recreate natural landscapes in miniature (缩略图), is nowhere better illustrated than in the nine gardens, which reflect the profound natural beauty in Chinese culture and inspire people to pursue harmony with the world.”
Nowadays, relevant administrations have been trying to restore the historical landscapes of Suzhou’s classical gardens. Consequently, last year, a new project was launched allowing tourists in small groups to reserve places to enter the garden in the early morning before the regular opening time. Their visit ended with them completing the last step in making a traditional folding fan, adding a poem about the garden on its surface. The experience was also regarded as a way to help people understand the wisdom, elegance and philosophical worldview of the ancient Chinese literati (文人).
The delicate beauty of the gardens still flows via the canals that snake across Suzhou. Hardly felt, their strength in shaping the city’s character seems to last forever.

4 . 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.

7 . On September 7, 1991, the costliest hailstorm (雹暴) in Canadian history hit Calgary’s southern suburbs. As a result, since 1996 a group of insurance companies have spent about $2 million per year on the Alberta Hail Suppression Project. Airplanes seed threatening storm cells with a chemical to make small ice crystals fall as rain before they can grow into dangerous hailstones. But farmers in east-central Alberta — downwind of the hail project flights — worry that precious moisture (水分) is being stolen from their thirsty land by the cloud seeding.
Norman Stienwand, who farms in that area, has been addressing public meetings on this issue for years. “Basically, the provincial government is letting the insurance companies protect the Calgary-Edmonton urban area from hail,” Mr. Stienwand says, “but they’re increasing drought risk as far east as Saskatchewan.”
The Alberta hail project is managed by Terry Krauss, a cloud physicist who works for Weather Modification Inc. of Fargo, North Dakota. “We affect only a very small percentage of the total moisture in the air, so we cannot be causing drought.” Dr. Krauss says. “In fact, we may be helping increase the moisture downwind by creating wetter ground.”
One doubter about the safety of cloud seeding is Chuck Doswell, a research scientist who just retired from the University of Oklahoma. “In 1999, I personally saw significant tornadoes form from a seeded storm cell in Kansas,” Dr. Doswell says. “Does cloud seeding create killer storms or reduce moisture downwind? No one really knows, of course, but the seeding goes on.”
Given the degree of doubt, Mr. Stienwand suggests, “It would be wise to stop cloud seeding.” In practice, doubt has had the opposite effect. Due to the lack of scientific proof concerning their impacts, no one has succeeded in winning a lawsuit against cloud-seeding companies. Hence, private climate engineering can proceed in relative legal safety.

8 . 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. |
9 . If anyone had told me three years ago that I would be spending most of my weekends camping, I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me.

I was, nevertheless, talked into going on another fun-filled holiday in the wilderness.
| A．This time there was no tent. |
| B．Things are going to be improved. |
| C．The trip they took me on was a rough one. |
| D．I was to learn a lot about camping since then, however. |
| E．I must say that I have certainly come to enjoy camping. |
| F．After the trip, my family became quite interested in camping. |
| G．There was no shade as the trees were no more than 3 feet tall. |
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.
