A fisherman I know named Joar Hesten called me late in April 2019. A white whale was swimming around his boat near the northern tip of Norway. It appeared to be wrapped in a tight strap (背带), and Hesten didn’t know what to do. White whales are usually found in pods in areas with ice and glaciers — rarely alone along the Norwegian coast. As a marine (海洋的) biologist, I knew that the strap needed to be removed as soon as possible.
We contacted the Norwegian Directorate of Fisheries Sea Surveillance Service. When inspector Jorgen Ree Wiig and his crew met with the fishing boat, the nearly 12-foot-long male eagerly engaged with them. He’d clearly been trained. The mystery deepened when Hesten got into the water to remove the strap. Attached to the strap was a camera mount (支架) with the words “Equipment St. Petersburg”.
A week after his discovery, Hvaldimir — the whale, followed a sailboat to Hammerfest harbor, about 25 miles from where he was first spotted. That’s where I photographed him in early May. I had traveled to Hammerfest to determine his physical condition. He was thin: He wasn’t eating on his own and seemed unlikely to survive in the wild. Later the authorities decided to feed him; his meals became daily tourist attractions in Hammerfest.
Training such a whale is expensive and time-consuming, yet no one claimed him. The Norwegian Police Security Service got on the case, and a German journalist used crowdsourcing to track the strap logo to an outdoor-equipment supplier in St Petersburg.
In June Hvaldimir left Hammerfest, in much better shape than when he arrived. Since then he has traveled along the coast of northern Norway, apparently feeding himself. Many people have opinions about what to do with Hvaldimir. Should the lone whale be placed in a dolphinarium (海豚馆), moved to a habitat, or just left to himself ? So far, he seems to be doing fine on his own.

【推荐1】Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive because of warming oceans from climate change.
Scientists studied epaulette sharks, which live off Australia and New Guinea. They found that warmer conditions sped up the sharks growing process. That meant the sharks were born earlier and very tired. The findings could be used in the study of other sharks, including those that give birth to live young.
The scientists studied 27 sharks. Some were raised in average summer water temperatures, about 27 degrees Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures. They also showed reduced energy levels.
Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies that look like decorations on some military clothing.
One study this year found that worldwide numbers of oceanic sharks and rays dropped more than 70 percent between1970 and 2018. Overfishing is a main concern,while climate change and pollution also threaten sharks.
Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia. She is the lead author of the epaulette shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong enough survive for long in the wild.
She added that if the sharks are born smaller than usual, they are probably going to have to start looking for food sooner — and they’re going to have less time to adjust to their surroundings.
The study should serve as a warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.

【推荐2】The United States Fish and Wildlife Service has identified 23 species it says are now extinct. Most of the species had been found in states in the southeastern U.S. Eleven species lived in Hawaii or Guam.
Perhaps the best-known species on the list is the ivory-billed woodpecker. There had been unconfirmed sightings of the bird over the past 20 years. That led to search operations in parts of Arkansas, Louisiana, Mississippi and Florida. But none of the woodpeckers were found.
Other species on the list had only been identified in the wild a few times and never seen again. One example is the flat pigtoe found in Alabama and Mississippi. In such cases, the species likely started disappearing shortly after being discovered.
In declaring a species extinct, the Fish and Wildlife Service removes it from its Endangered Species Act (ESA). The purpose of the ESA is to call attention to species with the greatest need for protection.
All 23 species were thought to have at least a small chance of survival when added to the ESA list. Only 11 species have been previously removed because of extinction in the nearly half-century since the ESA was signed into law.
The Fish and Wildlife Service warned that climate change, combined with other environmental pressures, could make such disappearances more common. As an example, it said nearly 3 billion birds have been lost in North America since 1970.
Cornell University bird biologist John Fitzpatrick is a leading figure in the hunt for the ivory-billed woodpecker. He told The Associated Press he thinks it was too early to declare the birds extinct. “Little is gained and much is lost,” he said of the declaration process.
Fitzpatrick led a 2005 study that claimed the woodpecker had been rediscovered in eastern Arkansas. He said removing a species from the ESA reduces public attention that is needed to help continue environmental protection efforts.

【推荐3】Legend has it that centuries ago, manatees (海牛) used to be mistaken for mermaids, so a sight last week at one Florida state park would have put ancient sailors in shock.
Blue Spring State Park is home to one of the largest winter gathering sites for manatees in Florida, and recently, the park reached a new record when the number of manatees spotted in one group was nearly 1,000.
Manatees typically flock to the park during the winter months. According to a Facebook post from the non-profit Save the Manatee Club, January 21 was one of the coldest mornings of the Florida winter season so far. The temperature of the St. Johns River, which Blue Spring sits on, was recorded at 14.9 ℃.
To survive the cold winter weather, manatees will seek out water that is typically warmer than 20 ℃. This is because despite their thick-looking bodies, the blubbery animal affectionately known as the sea cow only has “about an inch of fat and a very slow metabolism (新陈代谢), meaning they cannot easily stay warm,” says the state park.
Since their spring water remains at a constant 22.2 ℃, and is protected from human recreational activity, Blue Spring makes the perfect manatee shelter during the colder months. “What’s more, many manatees rely on artificial warm water sources from power plants, and these might be going off line in the near future. So having some of these manatees come to these natural warm water sites and finding them is really encouraging,” says Cora Berchem, a research associate and the director of multimedia at Save the Manatee Club.
According to the Florida Fish and Wildlife Conservation Commission, there are anywhere between about 7,000 to 11,000 manatees in Florida, which represents a large increase over the past 25 years.

【推荐1】A young man returns to his hometown of Colombia. He visits the house where he lived as a child. Here, he remembers the most important memories of his childhood. Standing in front of his old house, the young man makes an important decision. He says to himself, “I will start my life over again. I will become a writer.”
This man is world famous writer. Marquez.
Marquez was born on March 6, 1928. During his early life, Marquez’s grandmother and grandfather told him many stories. His grandmother would tell him legends as if they were real. Marquez says that his grandmother’s way of storytelling later influenced his own methods.

For the next few years, Marquez wrote for many different newspapers. And in 1955, he published his first book called “Leaf Storm”.
For many years, Marquez knew he wanted to write about his grandfather’s house in Colombia. To write this book, Marquez and his wife had to sell almost all of their possessions to survive. But their sacrifice (牺牲) was worth it. The book, “One Hundred Years of Solitude” was immediately successful. And this book created a path for Marquez’s future success.
In 1982, Marquez was given the Nobel Prize in Literature for his book “One Hundred Years of Solitude.” He was the first Colombian and the fourth Latin American to win a Nobel Prize for Literature.

【推荐3】My father was attached to gardening by birth. One of my earliest memories is following Dad barefoot around in the garden with both hands blackened from digging (挖) in the soil. The garden is a wonderland full of possibilities.
As Dad grew older, he still loved gardening. Even when he was diagnosed with cancer, he still planted all sorts of plants. Sometimes, I would come over to visit. and we would walk together in the garden. But then something changed. Like the weeds that took over his garden, the cancer grew rapidly in Dad. I stayed with Dad twenty-four hours a day and I found myself in all kinds of uncomfortable situations with Dad until I promised to look after the garden.
Though I had heard the words of the doctor, what really made me believe that Dad was dying was the state of his garden. That year, he only planted tomatoes. Too tired to weed them, he just tied them with strong strings (绳子) to the fence and let them be. It made me sad to see them ignored, so I would come over and water them once in a while, and remove the weeds. I still remember the day I picked the last tomato from the vine (藤). That day was one of the saddest I had ever experienced in my life.
Three years ago, I decided to plant my own garden. I decided I would start out with a few tomatoes. That morning when I moved to the garden, something caught the corner of my eyes and I had to smile. It was my eight-year-old son Nathan, standing barefoot in the soil, happily playing in the soil.

【推荐1】In January 2017, a series of fires in central Chile’s La Maue region burned down over 457,000 hectares (公顷) of forest, leaving behind nothing but burnt ground. Now, three border shepherd dogs(边境牧羊犬) are helping replant it by doing what they love most, running.
Das, Olivia, and Summer, three female border dogs have been working hard to bring the forest burnt by fire back to life since March. They are essentially running and playing, but their work is important. The dogs’ owner, 32-year-old Francisca Torres, takes them to various areas of burnt forest in her truck, equips them with special bags which she fills with seeds of local plants. Then the dogs are sent out to run around and spread as many seeds as they can. When they return, she rewards them with snacks, fills up their bags and sends them out on another run.
Torres, who trains the dogs not to attack any wild animal while on seed spreading tasks, thinks border shepherd dogs are perfectly suited for the job, because of their intelligence, energy and speed. They’ve learned that they have to empty their bags in order to receive their tasty reward when they return, and can cover much more ground than a human ever could. Every day, they can cover up to 30 kilometers and spread around eight kilograms of seeds, while a person on foot could only cover 3 kilometers. Most importantly, they love what they do.
Replanting the vast burned-down forest in just a few days will take years, but Torres hopes that her dogs will bring back enough plants for some of the animals to return. Torres has seen some fields that are now totally green thanks to the work of Summer, Olivia and Das. In some of 15 forests that the three border shepherd dogs have been responsible for, grass is coming back, and small trees are beginning to push through the burnt earth. Hopefully, enough seeds will come up soon for animals to come back.

Sport is not only physically challenging, but can also be mentally challenging. Criticism from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.
The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches’ criticisms to heart and find faults in themselves.
Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find faults with youngsters’ performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.
1. An effective way to prevent the burnout of young athletes is_____________.
A.to make sport less competitive |
B.to increase their sense of success |
C.to reduce their mental stress |
D.to make sport more challenging |
A.it can help them learn more about society |
B.it enables them to find faults in themselves |
C.it can provide them with valuable experiences |
D.it teaches them how to set realistic goals for themselves |
A.believing that criticism does good to their early development |
B.without realizing criticism may destroy their selfconfidence |

【推荐2】Kaitlin Woolley and Ayelet Fishbach report in Psychological Science that a meal taken “family-style” from a central plate can greatly improve the outcome of later negotiations.
Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity(短缺)and increase a feeling of competition. However, they also reasoned that it could instead lead people to become more aware of others' needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.
For the first test they included 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed corn chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began.
The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules.
The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster(in 8. 7rounds)than those who did not(13.2 rounds). A similar experiment was conducted with 104 participants and Goldfish crackers(饼干), this time negotiating an airline's route prices. The results were much the same, with the food-sharers negotiating successfully 63. 3% of the time and those who did not share doing so 42. 9%of the time.
