1 . A five-year-old dog named Kelsey has been praised as a hero for helping to save the life of her owner who slipped in the snow and broke his neck.
The man, Bob, was alone when he left his farmhouse on New Year’s Eve to collect firewood.Expecting a journey of only several meters, Bob was wearing just long johns (衬裤), a shirt and slippers when he went outside, although the temperature was around -4℃.
After the accident, he was unable to move in the snow. Fortunately, Kelsey came to his assistance.
“I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10:30 p. m.,” Bob explained. “By the next morning, my voice was gone and I couldn’t yell for help, but Kelsey didn’t stop barking.”
Kelsey’s companion kept him warm by lying on top of him. She licked his face and hands to keep him awake. “Kelsey kept barking but never left my side,” Bob recalled. “I knew I couldn’t give up and that it was my choice to stay alive.”
Bob spent 20 hours in the freezing cold. When he finally lost consciousness, his dog kept barking. Finally, hearing the barking, Bob’s neighbor discovered him at 6:30 p. m. on New Year’s Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21℃. However, doctors were surprised to find that he didn’t have any frostbite (冻疮). They believed it was because of Kelsey’s determination to keep him warm. Dr. Chaim Colen, the doctor who treated Bob, said, “His dog really saved him.He was very fortunate.”
Bob said he was very grateful to both Dr. Colen and his Kelsey. “They saved my life. They are truly heroes!”

3 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

5 . At Sho Farm in northern Vermont, farmers Melissa Hoffman and Shawn Smith work hand in hand with the land and its inhabitants, and among them are hundreds of ducks. The ducks at Sho Farm are not being raised to be killed for food. Rather, they are naturally involved in farming operations, helping to manage pests and add fertilizer (肥料) to the soil.
In the beginning, Hoffman, who has a background in organic farming and ecology action, worked with ecologists and biologists to survey the plants and wildlife all around the area. This was “to understand who was living here, so that everything we did was in relationship to the life already here,” he says.
So, at Sho Farm, focus is placed on living harmoniously alongside other life and working with traditional ecological knowledge. Food is seen not as a commodity (商品) but as a relationship with land and life.
The methods of food production at Sho Farm, as well as the farmers’ philosophy of working with rather than against nature, are in sharp contrast to most modern agricultural systems. And that’s the point. “We’ve been talking a lot about the broken food system and the consequences of it to the environment, to wildlife, to the animals in animal agriculture and to human health,” says Hoffman, adding that it’s not just the food system that’s broken. “It’s the relationship between humans, non-human animals, land and nature.”
The ducks play a vital, integrated role on the farm, explains Hoffman, by naturally providing pest control, fertilizer and (fuel-free) land maintenance (维护), just as by-products of their existence. “We noticed where we summered groups of ducks and parts of the food system that were not doing very well. The following year, the food system was efficiently improved,” he says.
It’s a symbiotic relationship that works well. “Animals don’t have to be part of a farm in a commodity sense. They can be part of the farm as a partner,” Hoffman says. “They are wonderful partners.”

6 . When she first started learning about the climate change from one of her elders,Fawn Sharp was invited on a helicopter flight over the Olympic Mountains to survey the Mount Anderson glacier.But the glacier was gone,melted by the warming climate.Sharp had a deep sense of loss when she discovered the glacier wasn’t there anymore.
Loss is a growing issue for people working and living on the front lines of climate change.And that gave Jennifer Wren Atkinson,a full-time lecturer at the University of Washington Bothell,US,an idea for a class.
This term,she taught students on the Bothell campus about the emotional burdens of environmental studies.She used the experiences of Native American tribes(部落),scientists and activists,and asked her 24 students to face the reality that there is no easy fix—that “this is such an intractable problem that they’re going to be dealing with it for the rest of their lives”.
Student Cody Dillon used to be a climate science skeptic(怀疑论者).Then he did his own reading and research,and changed his mind.
Dillon wasn’t going into environmental work—he was a computer-science major.Yet,the potential for a worldwide environmental catastrophe seemed so real to him five years ago that he quit his job and became a full-time volunteer for an environmental group that worked on restoration(恢复) projects.
Six months into the work,he decided that Atkinson’s class was just what he was looking for—a place where he could discuss his concerns about a changing climate.
Atkinson said she hoped the class helped her students prepare themselves for the amount of environmental loss that will happen over their lifetimes.
“We are already changing the planet—so many species are going to be lost,displaced or massively impacted,” she said.“The future isn’t going to be what they imagined.”
1. Why did the author mention the case of Fawn Sharp?A.To lay a basis for Fawn Sharp’s further research. |

B.It made him realize a planet-wide climate disaster would happen. |
C.It encouraged him to be more involved in environmental protection. |
D.It discouraged him to work on restoration projects for the environment. |
7 . A month after Hurricane Katrina, I returned home in New Orleans. There lay my house, reduced to waist high ruins, smelly and dirty.
Before the trip, I’d had my car fixed. When the office employee of the garage was writing up the bill, she noticed my Louisiana license plate. “You from New Orleans?” she asked. I said I was. “No charge,” she said, and firmly shook her head when I reached for my wallet. The next day I went for a haircut, and the same thing happened.
As my wife was studying in Florida, we decided to move there and tried to find a rental house that we could afford while also paying off a mortgage (抵押贷款) on our ruined house. We looked at many places, but none was satisfactory. We’d begun to accept that we’d have to live in extremely reduced circumstances for a while, when I got a very curious e-mail from a James Kennedy in California. He’d read some pieces I’d written about our sufferings for Slate, the online magazine, and wanted to give us (“no conditions attached”) a new house across the lake from New Orleans.
It sounded too good to be true, but I replied, thanking him for his exceptional generosity, that we had no plans to go back. Then a poet at the University of Florida offered to let his house to me while he went to England on his one-year paid leave. The rent was rather reasonable. I mentioned the poet’s offer to James Kennedy, and the next day he sent a check covering our entire rent for eight months.
Throughout this painful experience, the kindness of strangers has done much to bring back my faith in humanity. It’s almost worth losing your worldly possessions to be reminded that people are really nice when given half a chance.

8 . Rainbow-coloured rubbish is the colourful waste created by a Swedish city with an unusual recycling(回收利用) system. Like many cities in Sweden , Eskilstuna has an excellent recycling record . It met the EU's 2020 target of recycling 50% of waste many years ago.
Almost everyone who lives here follows strict recycling rules at home. People are expected to sort their household waste into seven separate categories, including food, textiles, cartons and metal. But what really makes the system stand out is the bright colour code.
The reason for this becomes clear at the city's recycling plant. The bags arrive all mixed up because they're collected altogether, once two weeks from outside people's houses. But thanks to those bright colours, scanners can choose the bags and separate them without difficulty. The food waste in green bags is processed on site into mud to make biogas, which powers the city's buses. One of the benefits of this method of recycling is that there is less cross-pollution,so more of the recycled waste can actually be used to make new things.
Like the rest of Sweden, Eskilstuna is devoted to sending zero waste from its citizens to landfill. Waste that cannot be recycled is burnt at a local plant to generate electricity. This reduces dependence on fossil fuels like coal and oil , but does create greenhouse gases .
As countries around the world try to improve their recycling systems, some may look to Eskilstuna as an example to follow-as long as they think they can persuade their citizens to get busy sorting rubbish at home .
1. Why are bright colours used in Eskilstuna's recycling system?A.To reach the target of recycling 50% of waste. |
B.To reduce the citizens' burden of sorting rubbish. |

9 . In the 12th century, physician Ibn Zuhr conducted some animal research to assess the surgical procedures that could be applied to humans. Since then, animal testing has been considered the most efficient way to develop new drugs. New medical treatments and drugs are tested on animals first to determine their effectiveness or safety levels before they are finally tested on humans. However, it remains controversial whether it is morally right or wrong to use animals for experiments.
The use of animals for medical purposes is seen to be necessary by many scientists. Researchers usually begin their trials using rats. If the tests are successful, further tests are done on monkeys before using human beings. For testing, such tiered(分层的) rounds are important because they reduce the level of error and negative side effects. Some argue that animal testing has contributed to many life-saving cures and treatments and there is no adequate alternative to testing on a living, whole-body system. Moreover, there are regulations for animal testing that limit the misuse of animals during research. They serve as evidence that animals are well taken care of and treated well instead of being intentionally harmed.
However, some other experts and animal welfare groups have opposed such practice, considering it as inhumane(不人道的) and claiming it should be banned. According to Humane Society International, animals used in experiments are commonly subjected to force-feeding, radiation exposure, operations to deliberately cause damage and frightening situations to create depression and anxiety. They also hold the view that animals are very different from human beings and therefore are poor test subjects. Drugs that pass animal tests are not necessarily safe. Animal tests on the arthritis (关节炎) drug Vioxx showed it would have a protective effect on the hearts of mice, yet the drug went on to cause about 27,000 heart attacks before being pulled back from the market.
It’s safe to say that using animals for tests will continue to be debated in many years to come. Despite the benefits of animal testing, some of the concerns need to be addressed with adequate regulations to ensure that animals are treated humanely.

10 . Located in the Indian Ocean,the Maldives(马尔代夫) are among the most beautiful islands in the world,with white sandy beaches,clear water,and amazing coral reefs(珊瑚礁).The country depends on tourism,fishing,and shipping.But the rising sea level and the carbon pollution causing warming oceans are threatening(威胁) their existence.
The Maldives have asked for international help.They are a tiny country.The World Bank,the United States,the European Union,and many other groups have offered money to develop safeguards against climate change.
To protect the islands,the Maldives have built sea walls and increased the elevation(海拔) of important buildings and services such as the two international airports,which lie just 165 feet from the coastline.
They’re also building up islands such as the Hulhumale.The new island is surrounded by 9-foot sea walls.More than 40,000 people live there.The plan is to house 240,000,providing new opportunities for jobs.The goal is an excellent planned community with sustainable housing and buildings sensitive to the environment and needs of the people.
The government will move people living on smaller,lower-lying islands to the new built-up islands.The new islands offer free houses,new schools,health hospitals,fresh water,and waste treatment.Depending on tourism,the country hopes to build 50 more tourist islands.
“Climate change is happening,but we are not leaving the Maldives to the sea,” said Environment Minister Thoriq Ibrahim.The Maldives will protect their islands,people and tourism with new islands and ongoing island development against the rising sea level.
