1 . As AI becomes popular, researchers have noticed its influence on the environment. Training an AI system requires huge computing power and electricity, and the resulting CO₂ emissions (排放) are one way AI affects the environment. But its environmental effect is more than its carbon (碳)footprint.

Jesse Dodge, a scientist at the Allen Institute, says, "The influence of Al systems is going to be from their applications, not the cost of training them." David Rolnick, a computer scientist at McGill University, compares AI to a hammer (锤子) “The main effect of a hammer is what is being hammered,” he says, "not what is in the hammer." Just like a hammer which can either destroy things or build a house, Al can hurt or help the environment.

In 2019, ExxonMobil, an oil company, said it would use Microsoft’s app Azure. With the Al technology, it would increase its production and create billions of dollars. This means Microsoft's AI is directly contributing to greenhouse gas emissions. This is not the only AI application that could be environmentally harmful. AI behind the ads that jump out on Instagram or Facebook pages pushes customers to spend more on products like clothes. This in turn causes more emissions through more production and delivery.

But on the other side of the coin, there are AI applications that can help deal with environmental problems, such as the destruction caused by hurricanes. One such application is xView2, a program started by a U. S. organization. It can recognize buildings damaged and people trapped in natural disasters, reducing danger and saving time for rescuers.

AI could be a valuable tool in the fight against climate change—if the Al industry can reduce its harmful climate effects. "Both AI and climate rules have roles to play." Rolnick says. When creating Al rules, he suggests considering its applications, emissions, and other production costs. Further, Dodge adds that those AI professionals should help set up some value systems to limit the technology's use.

1. Where does the effect of AI systems on the environment come from according to Dodge?

A．The popularity of AI.	B．The emissions of CO2.
C．The way of applying AI.	D．The cost of AI training.

2. How does the writer develop Paragraph 4?

3 . On a recent sunny day, 13,000 chickens roam over Larry Brown’s 40 windswept acres in Shiner, Texas. Some rest in the shade of a parked car. Others drink water with the cows. This all seems random, but it’s by design, part of what the $6.1 billion U.S. egg industry bets will be its next big thing: climate-friendly eggs.

These eggs, which are making their debut now on shelves for as much as $8 a dozen, are still labeled organic and animal-friendly, but they’re also from birds that live on farms using regenerative agriculture — special techniques to cultivate rich soils that can trap greenhouse gases. Such eggs could be marketed as helping to fight climate change.

“I’m excited about our progress,” says Brown, who harvests eggs for Denver-based NestFresh Eggs and is adding more cover crops that draw worms and crickets for the chickens to eat. The birds’ waste then fertilizes fields. Such improvements “allow our hens to forage for high-quality natural feed that will be good for the land, the hens, and the eggs that we supply to our customers.”

The egg industry’s push is the first major test of whether animal products from regenerative farms can become the next premium offering. In barely more than a decade, organic eggs went from being dismissed as a niche product in natural foods stores to being sold at Walmart. More recently there were similar doubts about probiotics and plant-based meats, but both have exploded into major supermarket categories. If the sustainable-egg rollout is successful, it could open the floodgates for regenerative beef, broccoli, and beyond.

Regenerative products could be a hard sell, because the concept is tough to define quickly, says Julie Stanton, associate professor of agricultural economics at Pennsylvania State University Brandywine. Such farming also brings minimal, if any, improvement to the food products (though some producers say their eggs have more protein).

The industry is betting that the same consumers paying more for premium attributes such as free-range, non-GMO, and pasture-raised eggs will embrace sustainability. Surveys show that younger generations are more concerned about climate change, and some of the success of plant- based meat can be chalked up to shoppers wanting to signal their desire to protect the environment. Young adults “really care about the planet,” says John Brunnquell, president of Egg Innovations. “They are absolutely altering the food chain beyond what I think even they understand what they’re doing.”

For voyager and green promoter Zhai Mo, the 504-day non-stop voyage to the Arctic Ocean has stimulated his concern about the climate and awareness of his responsibilities.

Navigating more than 28,000 nautical miles (51,856 kilometers) in harsh conditions, Zhai, a (n)     1     Chinese explorer, returned to Shanghai on his aluminum sailboat on Nov 17, along with two crew members, becoming the first man to successfully circle, both ways, the Arctic Ocean without stop. “This non-stop Arctic Ocean circle route can be said to be     2    . We     3     both the northeast and northwest routes while previous explorers only chose one route. This is a self-challenge and transcendence in the history of human navigation,” the 54-year-old says.

Zhai undertook this task as an ambassador of the Chinese navigation science and marine public welfare, and also the ForNature Campaign of the United Nations Development Program. He set sail on June 30 last year to raise public awareness of global warming, climate change and land     4    . During the trip, he crossed the East China Sea, the Western Pacific, the Bering Strait, the Chukchi Sea, the East Siberian Sea and the Beaufort Sea. He saw dolphins, whales, walruses, sea lions and seals, as well as shoals of cod and wolf fishes.

“When we passed through the Northwest Pacific Ocean on our way back, we encountered three typhoons within a week, which     5     happened in the past,” Zhai recalls.

Zhai didn’t see any floating ice during his one-week voyage in the Kara Sea while the previous meteorological data showed ice there.

“My own experience tells me that climate     6     is obvious now,” Zhai says.

The voyage, to enter the Arctic Ocean from the Bering Strait before making a round trip returning to Shanghai, was planned to take four months, but the return schedule was delayed for more than a year. “As soon as we entered the Bering Strait, we encountered a polar cyclone. A large number of ice floes and icebergs were blown to the coast. However, the Arctic Ocean can only be     7     near land, so we had been carefully crossing between ice floes and icebergs for a long time and the speed was only 1 to 3 knots,” Zhai says. But for Zhai, the most difficult part of the whole voyage was around 75 degrees north. The Arctic Ocean is known as the “dead channel”, Zhai says, adding that the location where the Titanic went down was on his route and dotted with countless icebergs. After entering the iceberg region, Zhai navigated the sailboat while the two crew members went on watch to report on the menacing ice. Despite the precaution, the boat hit an iceberg near Greenland, causing water seepage below the waterline that had to be dealt with. Meanwhile, compasses and electronic goods on the boat failed because of the magnetic field. “I had never encountered this situation in sailing before,” says Zhai.     8    , he took a fiber optic compass specially used for high latitude navigation, and managed to leave this area with visual aids. In addition to ice floes and icebergs, Zhai and his team also faced severe tests such as heavy fog, strong winds and huge waves. When sailing through the Chukchi Sea, the boat navigated around a large area of ice floes and heavy fog resulting in visibility of no more than 10 meters. They spent nearly 11 hours to get just 50 nautical miles. “We tried to leave as soon as possible during our voyage in the Arctic Ocean,” he says, adding that there was a constant danger of being trapped by the ice.

Zhai was attracted by sailing when holding an art exhibition abroad in 2000. In 2007, he got a second-hand sailboat with simple supplies, such as instant noodles, pancakes and potatoes, and started his voyage trip around the world.

After that 35,000-nautical-mile voyage, Zhai     9     an Arctic Ocean journey. “Navigation is a comprehensive     10    . You should know not only astronomy but also geography. You also need to be a carpenter, fitter, hammerer and painter, and should be able to survive in a harsh, outdoor environment,” Zhai says.

He adds that he hopes more young people would participate in navigation, to promote and publicize the ocean awareness and navigation spirit. He is preparing for the third voyage trip around the world next year or the year after that. “Antarctica is also a very big challenge. I hope to explore more unknowns, and I also want to launch a transoceanic sailing competition.”

Last week I visited a small village to see the brown bears, what come to the villages at night to look at food. I waited with some tourist. As it grew dark, we see the huge black shapes of the bears. Those clever bears knew where to go for its dinner: the rubbish where there was lots of food people have thrown away. Although it’s wonderful to see the bears in the village, but it can only mean one thing: their habitat is disappearing. They would prefer to stay hiding in the mountain forests, but the trees have cut down for firewood. However, they cannot find enough food any more.

8 . Masses of ocean plastic are providing artificial habitat (栖息地) for otherwise coastal species, according to a new study published in Nature Communications. The study’s authors observed floating water bottles, old toothbrushes and waste fishing nets. The possibility exists that species may be evolving to better adapt to life on plastic.

A decade ago, marine researchers believed coastal species could not survive a trip across the inhospitable open ocean. Yet Japan’s 2011 tsunami (海啸), which sent some 300 species of Asian marine life riding floating plastic garbage onto North American shores, disproved that assumption.

Ocean plastic is “creating opportunities for coastal species’ biogeography to greatly expand beyond what we previously thought was possible”, Linsey Haram, a researcher and co-author of the study, said in a report.

The concept of species-covered plastic may sound like the story of ocean species’ victory in spite of human pollution. But that’s not quite the case, explains Juan José Alava, PhD, an expert at the University of British Columbia. In addition to transporting non-native species to new habitats where they may become invasive and destructive, the plastic is “basically an ecological trap”, says Alava. “That’s because small species on the floating structure may attract bigger animals to come for food. When these creatures enter garbage areas for food, they run a high risk of eating and/or becoming caught in plastic and dying.”

While scientists have found some types of bacteria (细菌) are able to break down plastic, thereby cleaning up garbage, it’s unlikely that the marine animals will have any such effect. “The 2021 UN report was clear that the increasing plastic pollution is putting the health of all the world’s oceans and seas at risk,” says Alava.
