1 . Birders get nervous when they see landscapes covered in wind turbines (涡轮机). When the wind gets going, their blades (叶片) can turn around at well over 200km per hour. It is easy to imagine careless birds getting cut into pieces and wind turbines do indeed kill at least some birds. But a new analysis of American data suggests the numbers are negligible, and have little impact on bird populations.

Erik Katovich, an economist at the University of Geneva, made use of the Christmas BirdCount, a citizen-science project run by the National Audubon Society. Volunteers count birds they spot over Christmas, and the society gathers the numbers. He assumed, reasonably, that if wind turbines harmed bird populations, the numbers seen in the Christmas Bird Count would drop in places where new turbines had been built. Combining bird population and species maps with the locations and construction dates of all wind turbines, he found building turbines had no noticeable effect on bird populations.

Instead of limiting his analysis to wind power alone, he also examined oil-and-gas extraction (开采), which has boomed in America over the past couple of decades. Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon. When drilling happened in migration centers, feeding grounds or breeding locations, bird numbers instead dropped by 25%.

Wind power, in other words, not only produces far less planet-heating carbon dioxide and methane than do fossil fuels. It appears to be significantly less damaging to wildlife, too. Yet that is not the impression you would get from reading the news. Dr Katovich found 173 stories in major American news media reporting the supposed negative effects that wind turbines had on birds in 2020, compared with only 46 stories discussing the effects of oil-and-gas wells.

2 . People have always believed that nature is good for health and happiness. According to scientific studies, being in nature makes people less stressed. In a recent experiment in Japan, one group of people were asked to walk through a forest while another group had to walk through a busy city.     1    . However, researchers found that after the walks, the people who had walked in the forest had better moods, less anxiety and even lower blood pressure. So the experiment showed that it was being in nature that helped people feel less stressed, not just the walk.

Gregory Bratman from Stanford University in the United States found in experiments that a walk in nature could have important cognitive (认知) benefits, improving a person’s memory and creativity.     2    . Teachers find that when children are enjoying the natural world, their awareness and creativity are improved, along with their reasoning and observational skills.

Why does being in nature bring so many benefits for us?     3    , so we have an instinctive (本能的) love for it. Even just looking out of the window at a beautiful tree can help us feel less stressed.

Scientists also think that being in nature helps our brain recover from a lot of activities that we usually do during the day such as working on math problems or using our cell phone.     4     — putting all our attention into one thing, which can make us feel tired. But when we are outside, we use undirected attention. We see an interesting cloud or a beautiful flower, and our attention moves quickly and easily from one thing to another. So being in nature gives our brains the chance to rest.

    5    . For many of us, nature is something we can enjoy just by walking out of our door. So enjoy the nature around you!

A．The walks were equally long and hard

B．Regular workouts are surprisingly helpful

C．One idea is that human beings come from nature

D．Nature’s benefits have been scientifically confirmed

E．In these activities, we use a lot of directed attention

F．Being in nature increases people’s mental health as well

G．We can see this in schools where outdoor learning has been introduced

3 . Architects often spend months or even years perfecting a design to express their ideas more clearly, convey additional information, or outline the right proportions for a building. However, the urgent issue of climate change is placing new demands on their work. For example, in July, Super Typhoon Doksuri battered China, affecting more than 2.66 million people in Fujian Province alone.

Green architecture that conserves energy and reduces carbon dioxide emissions offers a solution, and concerted efforts have been made in diverse research fields over the past three decades to minimize heat loss. In addition, new buildings have to be tailored to the needs of people’s lifestyles.

Ren Jun, a professor at Tianjin University’s School of Architecture, who designed the first near-zero energy house in China in December 2019, said, “You can construct low-energy, environmentally-friendly houses, but if the interior design and environmental quality don’t meet residents’ requirements, these properties won’t be suitable to live in.”

The near-zero energy house, located-in Banbidian village in Beijing’s southern district of Daxing, won the International Design Award in the United States in January last year. The 400-square-meter property, which stands at the entrance to the village, runs on solar power gathered from rooftop panels, with the addition of a small amount of power from the grid (电网).

Ren said the first obstacle to conserving energy in the property was heat retention, which he attempted to achieve by keeping the indoor temperature at a certain level. The property is divided into five areas: a solar garden in the front yard, a central lounge, a water courtyard, a sponge zone, and a back room. For the exterior walls, Ren used three types of insulation (隔热层), including plastic foam, each about 25 centimeters thick.

Ren also looked for ways to deal with emissions at the house. He decided to install a ventilator, which pipes air that is polluted and replaces it with fresh air from outside in every room at the property.

Ren said it would take three to five years before more ultralow or near-zero energy buildings appeared in Chinese cities.

5 . In the Seychelles archipelago (塞舌尔群岛) in East Africa, flooding and erosion (侵蚀) caused by rising sea level pose an incoming threat to the country’s many low-lying islands. At the same time its mangrove forests (红树林), which serve as a vital aspect against these impacts, are disappearing: Approximately 70% of Seychelles mangroves have been destroyed since the late 1700s due to human-driven development and agriculture as well as soil erosion from sea-level rise.

Today the Seychelles Government is working with local community leaders to restore the mangroves, and not just for protection against rising sealevel. Research shows that these forests can store about 2.5 million tonnes of CO₂ (equal to taking 500,000 cars off the road for a year), directly helping to fight climate change. They also provide a breeding ground for fisheries, a sector that contributes one-fifth of the country’s GDP, benefiting local communities’ livelihood and helping to protect the islands’ lively biodiversity (多样性).

While the concept of using nature to benefit both lives and lands is by no means new, global interest in “nature-based solutions” has skyrocketed in recent years. Many now see nature-based solutions as a key approach for addressing not only climate change but a range of social, environmental and economic challenges—from biodiversity loss, food security and air pollution to disease control and declining local economies.

Yet there remains widespread debate about what exactly constitutes a nature-based solution as well as how to best include these strategies into broader climate and conservation efforts. This indetermination has contributed to significant under-investment: It’s estimated that to limit temperature rise to below 1.5 degrees C (degrees F), hold back biodiversity loss and control land degradation (恶化), annual investments in nature-based approaches must be three times by 2030.

As nature-based solutions continue to rise on the global agenda, building a more consistent understanding around the concept and its implications will be key to raising support for effective, extensive solutions that benefit both people and the planet.

8 . Vast lands of America are dominated by corn, nearly 100macres of it, stretching from Ohio to the Dakotas. What once was forest today produces the corn that feeds people, cattle and, when made into ethanol (乙醇), cars.

Now, the nation’s airlines want to power their planes with corn, too. United Airlines signed a deal with a Nebraska ethanol company to buy enough sustainable fuel, to power 50,000 flights a year. The government could decide on its tax incentives (税收激励) for the industry as soon as December. “Mark my words, the next 20 years, corn farmers are going to provide 95% of all the sustainable airline fuel,” President Biden said in July.

The airlines’ ambitious goal would likely require nearly doubling ethanol production, which airlines say, with great expectation, would decrease their greenhouse gas emissions. If they succeed, it could transform America’s Corn Belt, stimulating farmers and ethanol producers, but potentially further damaging one of the nation’s most important resources: groundwater.

Corn requires a lot of water to grow and it can take hundreds of gallons to produce a single gallon of ethanol. But as airlines take the idea of ethanol, the vital groundwater faces serious risks. “We’re on track to massively increase water usage without any real sense of how sensitive our groundwater is,” said Jeffrey Broberg, who is concerned about groundwater in Minnesota, a major corn state.

The Department of Energy said in a statement that “water use is a critical part of the conversation surrounding bio-energy sustainability”. It pointed to a 2022 department study that concluded that the United States could significantly reduce pressure on groundwater by shifting fuel production away from water-intensive crops like corn, instead growing more crops that don’t require irrigation (灌溉), like various types of straw, grasses and trees. Hopefully, a better approach will be soon studied and adopted.

9 . For the history of life on Earth, organisms have relied on the light of the sun, moon, and stars to find their way and schedule their lives. While the beginning of electric lighting in the late 19th century may have benefited humans, it has caused problems in the natural world. Among the impacts of artificial light at night(ALAN), light pollution lures migrating birds to cities with shocking consequences, contributes to the alarming decline in insect populations, and convinces sea turtle babies to amble(缓行)away from the water instead of towards it.

Now, a new study from the University of Plymouth adds another disappointing finding about how ALAN is affecting the creatures with whom we share the planet: Light pollution from coastal cities can trick corals(珊瑚)into reproducing outside of the optimum times when they would normally reproduce.

Using a combination of light pollution data and spawning(产卵)observations, researchers were able to show for the first time that corals exposed to ALAN are spawning one to three days earlier and closer to the full moon compared to those on unlit corals. “That shift may reduce the survival and fertilization success of gametes(配子)and genetic connectivity between nearby lit and unlit coral systems,” they explain.

“Corals are among the most biodiverse, economically important, and threatened ecosystems on the planet,” write the authors of the study.

“Climate change has led to mass bleaching(褪色)events. Habitat destruction, fisheries, and pollution have reduced corals substantially since the 1950s,” they write, adding, “The complete loss of corals is anticipated over the next 100 years.”

If we want to reduce the harm ALAN is causing, we could perhaps look to delay the switching-on of night-time lighting in coastal regions to ensure the natural dark period between sunset and moonrise when coral reproduction remains undisturbed.

10 . Think about what you like to wear on the weekend. There’s a good chance that you like to put on a pair of blue jeans（牛仔裤）. At any moment, about half of the world’s population is wearing jeans. But according to a new study, our love for jeans may be bad for earth. The cloth used to make jeans might be putting some sea animals in danger. Every time we wash our jeans, small bits of it will flow out of our washing machines and into the world’s rivers, lakes and sea.

You might wonder: isn’t the cloth made of something natural? How can it become a danger to nature? Well, when making jeans, the cloth is treated with many types of man-made chemicals. Scientists aren’t yet sure how the chemicals（化学品） in the cloth might harm animals.

In the study, the scientists also washed jeans to see how many bits of the cloth on average each pair would drop per wash. The answer was worrying: about 50,000. Not all of them make their way into the environment. Wastewater treatment plants hold back 83 to 99 percent of them. This may sound pretty good. However, one percent of 50,000 are still 500 per wash. Now think about the number of jeans around the world and the times each of them gets washed. As a result, a large amount of the cloth still gets into the environment.

Does this mean we shouldn’t wear jeans? Probably not. “We need to buy fewer clothes and only wash them when we truly need to do it,” says Sam Athey, one of the scientists. “You don’t need to wash your jeans after having worn them only a few times.”

1. What does the underlined word “it” in paragraph 1 refer to?

A．The danger.

B．The cloth.

C．The earth.

D．The sea animal.
