1 . Scientists in England are using two selfdirected water vehicles to explore the animal and plant life of the Celtic Sea.
The Celtic Sea is a body of water off the southern coast of Ireland. The area is known for its unusual sea life. Scientists want to know why sea creatures are so attracted to this part of the Atlantic Ocean.
One of the research vehicles is powered by batteries (电池). It collects information for the National Oceanography Center in Southampton, England, and the World Wildlife Fund. The vehicle’s low energy requirements permit it to stay floating on water for up to 30 days. Reports of what it finds in the Celtic Sea are sent by satellite.
Stephen Woodward is an engineer who helped design the vehicle. He says the vehicle has equipment that can discover small organisms called zooplankton (浮游动物) and fish. He adds that other sensing equipment measures water currents and other features of sea life. The vehicle also creates a map of the sea.
Another vehicle is powered by the sun and the wind.It can stay floating on water for months. The robotic vehicle sends information about the socalled biodiversity hotspots. A biodiversity hotspot is an area of an ocean that has a lot of plant and animal life activity.
Lavinia Suberg is one of the scientists studying the Celtic Sea. She says productive ocean areas, like the Celtic Sea, attract zooplankton. The zooplankton then attracts fish. She adds that areas with a large increase of fish often attract sea mammals and birds.
Using these robotic ocean vehicles greatly reduces the cost of exploring the sea with manned laboratories. Scientists can spend more time analyzing the collected information. They say the research will give them a better understanding of the needs of the Celtic Sea for future management and protection.

2 . Perhaps thousands of people have searched for a bronze chest full of gold and jewels hidden in the Rocky Mountains between Santa Fe and the Canadian border hidden by a millionaire adventurer. At least four people died in their search for the treasure.
But it's all over now. Fenn's Treasure has been found. The 89-year-old adventurer named Forrest Fenn, who created the treasure hunt, announced the news via his website. “I don't know the person who found it, but the poem in my book led him to the precise spot,” Fenn wrote. “The treasure was confirmed by a photograph the lucky finder sent me.”
Forrest Fenn, the man who started the hunt, lives in Santa Fe. He was a pilot in the Vietnam War and later accumulated his wealth as a dealer in art and antiques. Fenn was diagnosed(诊断) with cancer in 1988 and had planned to die peacefully in the woods with his treasure. But when his cancer became less serious, he changed his plan, eventually writing the poem that described his dream resting place, which is where he hid the treasure. The poem appeared in a memoir called The Thrill of the Chase. Fenn said that the chest wouldn't be found by accident; only a treasure hunter who correctly interpreted the clues(线索) would find it.
Several treasure hunters went missing while attempting to find the chest, including hunter Jeff Murphy and Mike Petersen, both of whom went missing in Yellowstone National Park in 2017. Fenn said that he had never been to the Yellowstone National Park, and that the treasure was not in a dangerous place. "It was in the thick forest of the Rocky Mountains and had not been moved from the spot where I hid it more than 10 years ago," Fenn wrote on his website. It is illegal to remove anything from a national park, which would cause trouble in legally claiming the treasure if it was found there.

3 . In 1998, people in Na Doi, a quiet village in northwest Thailand, noticed that their fish catches in the nearby Ngao River were declining. The fish they did manage to net were also getting smaller. Together, Na Doi’s 75 households decided to try a new solution: they would set aside a small stretch of river to be strictly off-limits to fishing.
The rules are usually simple: no fishing of any kind in an agreed-upon area marked by flags or signs. While freshwater reserves won’t solve everything, in places where fish populations are under pressure, they can give species much-needed breathing room to rebuild their numbers, ultimately making them better able to weather other environmental problems.
Na Doi was the second village in the Ngao River valley to adopt this pioneering approach to freshwater fisheries management. Since the late 1990s, at least 50 other villages there have done the same. As a whole, the entirely grassroots-led reserves have been surprisingly successful, according to findings recently published in Nature. Most importantly, the Thailand case provides probably the best real-world proof that fisheries reserves can benefit not just oceans, but freshwater, too
In 2012. Aaron Koning, then a doctoral student at the University of Wisconsin, began investigating the Ngao River valley reserves to see how widespread and successful they truly were. Koning found, not surprisingly, that older and bigger reserves were more successful, because they offered more time and space—including more kinds of habitat—in which to rebuild fish populations and re-establish rare species. But even reserves established in the last couple of years showed clear benefits from being spared intense fishing pressure. “Reserves that were located closer to a village tended to have an advantage,” Koning says, “probably because villagers were better able to enforce the rules.”
By comparing different systems and approaches around the world, Koning and his colleagues hope to identify common factors for success that could be tailored to diverse rivers and lakes.

4 . Every week in China, millions of people will sit in front of their TVs watching teenagers compete for the title Character Hero, which is a Chinese-style spelling bee. In this challenge, young competitors must write Chinese characters by hand. To prepare for the competition, the competitors usually spend months studying dictionaries.
Perhaps the show’s popularity should not be a surprise. Along with gunpowder and paper, many Chinese people consider the creation of Chinese calligraphy(书法) to be one of their primary contributions to civilization. Unfortunately, all over the country, Chinese people are forgetting how to write their own language without computerized help. Software on smart phones and computers allows users to type in the basic sound of the word using the Latin alphabet. The correct character is chosen from a list. The result? It’s possible to recognize characters without remembering how to write them.
But there’s still hope for the paint brush. China’s Education Ministry wants children to spend more time learning how to write.
In one Beijing primary school we visited, students practice calligraphy every day inside a specially decorated classroom with traditional Chinese paintings hanging on the walls. Soft music plays as a group of six-year-olds dip brush pens into black ink. They look up at the blackboard often to study their teacher’s examples before carefully attempting to reproduce those characters on thin rice paper. “If adults can survive without using handwriting, why bother to teach it now?” we ask the calligraphy teacher, Shen Bin. “The ability to write characters is part of Chinese tradition and culture,” she reasons. “Students must learn now so they don’t forget when they grow up.” says the teacher.
1. What can we learn about the Character Hero?| A．It’s open to people of all ages and all walks. |

5 . That morning, I dropped our eldest at kindergarten and returned home to let our two younger children play while I worked on my medical report. It was a wonderful chance to work from home, but it hit me that my career in hospital wasn't making a difference in anyone's life. I needed something that would stretch my limits and push me to grow. My career enabled me to work from home. I could work from home, and become a foster mother, providing safety for a child who needed it desperately.
On Monday morning. I picked up the phone and dialed the number I had Googled for the nearest Department of Children's Services. The man on the other end was receptive to my questions and explained the next step of training, involving eight weeks of classes designed to prepare and educate foster parents. We continued through all the classes, the home visits, background checks, and seemingly endless steps.
Five long months after we were approved, the phone rang. In the middle of the night, I woke my husband and rushed to East Tennessee Children's Hospital. Our placement was waiting for us in the emergency room, sick and lack of nutrition. It didn't take long for us to realize the full depth of her suffering. Six months later, her half-brother came to us by our request. We now had five children under our care.
On August 12, 2016, our family of seven walked into a small courtroom. The children's lawyer and social worker were there. With just a few words, our adoption was finalized. These two amazing children weren't going home, because they were already home. We are their forever family, and they are our forever children. We may not be able to change the entire world, but we have changed the world entirely for our new children.

6 . A new device works like a solar panel, except that it doesn't harvest energy from the sun. It absorbs energy from the cold night sky.
A prototype(原型)of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It also could power electronics in remote or low-resource areas that lack electricity.
The device makes use of the temperature difference between Earth and outer space.It then uses that difference to create electricity. As long as one side of it is cooler than the other, the generator can produce electricity.The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent(透明的)cover and surrounded with insulation(隔热材料)to keep out heat.The bottom of the generator is attached to an exposed aluminum plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.
Researchers tested a 20-centimeter prototype one clear December night in Stanford,California. The generator produced up to about 25 milliwatts of power per square meter of device. That was enough power to light a small light-emitting diode, or LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. To do that, the system might need more insulation around the cool top plate.
The device also could help power remote weather stations or other environmental devices,says Aaswath Raman. He is a materials scientist who worked on the device at the University of California, Los Angeles. This may be useful in polar regions that don't see sunlight for months at a time,Raman says. “If you have some low-power load and you need to power it through three months of darkness, this might be a way.”

7 . Do you like running enough to make it a habit? Tierney Wolfgram does; she has made running a lifelong career and isn't stopping.
In February, the 16-year-old from a high school, US, competed at the 2020 US Olympic Trials. She finished the marathon(42.195 km)with a time of 2:42:47 as the youngest competitor in the race and ranked 76th out of 390 runners. However, the cross-country(越野的)season was postponed to winter because of the COVID-19. So she jumped at the opportunity to train for another race-the Parkway Marathon in California. In November, Wolfgram broke the Women's American Junior marathon record with her time of 2:31:49. The old record was 2:34:32, which had stood since 1984.
“I'm completely stunned, ”said Wolfgram's coach. “I knew she was going to break it, but she really showed out！”
During the run, Wolfgram once hit a wall pretty hard, but she overcame it to finish. “I guess I can say I gave it my all, ”she told Runner's World. “When I finished, all I was thinking was I felt super happy,” Wolfgram said This was only her third marathon. In 2018, when Wolfgram was 15 years old, she ran her first marathon just because she wanted to see if she had the ability to do it. “I believed that I would get faster as the distances got longer. . . I'm still glad that I did it. ”
When preparing for that first marathon, she ran up to 120 miles per week. Although her parents didn't have any background in running, they helped Wolfgram train. At first, her dad would take her out in the morning and run about 13 miles. The distance would gradually increase each day. On top of her runs in the morning, she would do cross-country practice after school.
Now Wolfgram will consider attending the Olympics Games in 2024 after it's scheduled.

8 . With their large glass windows and clear views of the hospital’s newest arrivals, it’s hard to imagine hospitals without newborn nurseries. But how did this slightly unusual concept of putting babies on show come into being?
Well, they’re not really for putting babies on show. Firstly, they were created as an area for nurses to take care of all of the new babies, separate from their mothers. Newborn nurseries have been around pretty much since moms started having babies in hospitals. In the early 1900s, hospitals replaced homes as the primary place to give birth. Hospitals built delivery rooms, and those wards had nurseries with windows.
According to Smithsonian.com, a 1943 publication gave two main purposes for the nurseries. The first purpose was to allow the relatives to see the new babies. The windows, however, were to keep the babies safe and clean while they were being admired by relatives. And that sanitary concern is right and reasonable. Babies’ immune systems are not yet developed, which has to do with the frightening reason you should be careful about letting people kiss your new baby. However, the Smithsonian.com article does admit that solid walls would be even more effective at keeping bacteria and viruses out than windows. Not to mention they would be more cost-effective. So, yeah... the primary purpose is still to look at the cute babies. Some hospitals would offer individual viewings so that relatives could have some quality time with their new member. In the mid- to late twentieth century, these nursery viewings were often the first time fathers got to see their new babies.
Today, though, the nurseries mean a lot to many hospital visitors and family members. Dotti James claims that "the nursery window has become a destination for patients and families from other parts of the hospital experiencing a health crisis...Standing outside the nursery, seeing the babies...can give hope to families trying to deal successfully with something difficult." It’s pretty much a universal truth that healthy babies are an immediate mood booster(令人鼓舞的事情).

9 . 54-year-old Abdul has a special job. He has been working as a living statue (活体雕像) for over three decades, standing perfectly still for six hours a day and resisting people' s attempts to make him move or smile, anything that proves he is a living person.
Abdul, known as “India's Statue Man”, has been performing his daily routine ever since 1985, soon after getting a job as a security guard. His boss had recently traveled to the UK, where he was So impressed by the statue-like members of the Royal Guard outside Buckingham Palace that he wanted to do something similar back home. So he had his guards receive three months of training, where they would sit perfectly still for around four hours. They weren't allowed to talk or smile, eat, drink, or even shoo away a fly if it sat on their faces. In the end, Abdul proved the best of the group, So he got the strange job.
Abdul isn't the only person in the world acting as a living statue, but what makes him special is the fact that he can do it for as long as six hours without even blinking his eyes. Once, a $ 155 prize was put up for anyone who can make him move a muscle. But try as they might, no one has ever succeeded. Actually, Abdul tries to move about as much as he can in his spare time, and only eats healthy home-cooked food, to keep his body in shape. But he claims yoga has been the biggest help. In the 32 years, Abdul has become a famous person in India and other Asian countries. Many Bollywood stars have come to witness this living statue and try to finally make him move, but none have succeeded.
Abdul earns about 10,000 rupees ($ 156) a month, which is enough to support his family, but definitely not enough to encourage his children to follow in his footsteps. It's just too stressful and taxing on the body. “Despite all the hardship and health problems, I love my job and I am thankful to people for the love and respect they have showered on me” he says, “When the time comes, I want to die playing a statue.”

10 . On Saturday 24 August 1918, it was raining cats and dogs and thundering over a city called Sunderland on the northeast coast of England. The storm lasted for only about ten minutes. People were surprised to see that it was not just rainwater falling from the sky. There were fish falling down, too! People came out to find out what was happening. They could not believe their own eyes. There were thousands of fish — sand eels— lying on the ground. They were about seven centimeters long, and all were frozen solid.
Sand eels swim together in large groups, often in sandy water, and are often found in large numbers in the North Sea, which reaches out to the east of Sunderland. How was it possible for these sand eels to fall from the sky and land on Sunderland?
Scientists believed the heavy thunderstorm that afternoon may have caused a waterspout. Waterspouts can be formed when strong winds move quickly in a circle over water. They are so powerful; anything less than one meter in length can be taken into them and forced into the clouds. The clouds carry whatever has been taken into them for long distances — sometimes over 150 kilometers. It’s very cold up there and everything soon freezes solid.
For hundreds of years there have been reports of small animals being taken into the sky through waterspouts. In 2009, dead tadpoles rained down on the city of Nanao in Japan. In 2012, fifty kilos of prawns fell from the sky over Sri Lanka. In 2017, fish fell on the coastal city of Tampico In Mexico.
It must be a very strange experience to see fish raining down on you. It would probably hurt if one fell on your head! With climate change, global warming and many reports of terrible natural disasters, will the time ever come when it may really begin to rain cats and dogs?
