3 . Students at St. Stanislaus High School in Mississippi are among the volunteers along US coasts raising oysters (牡蛎) to help restore, or repair weakened reefs (礁). Oyster reefs are an important part of coastal environments. Each oyster cleans 95 to 190 liters of water a day. The reefs provide living space for shrimp, crabs and fish. They also protect coastlines. In the states of Maryland, Virginia, Mississippi, and Alabama, now there are more than 1,000 oyster gardens. Most of them are in wire cages hanging from private ports.
Colin Wood, one student looking after the St. Stanislaus garden, said he was excited by the hands-on work. “I didn’t realize oysters had a big influence on the environment. And 50,000 to 55,000 adult oysters grown here each year go to reefs in Mobile Bay,” he said.
In the 1950s, an average of 37,400 tons of oysters were taken yearly from partly salty waters in the US. But US oyster harvests fell sharply in the 1990s. Data showed the cause of the drop could be overharvesting, pollution, pests and other problems. Then oyster gardening started.
Oyster gardening uses many of the same methods as farming. Farmers around the country grow oysters near the surface of water. Oysters develop much faster where the water holds more food they eat and enemies can be more easily removed. But the oysters are not being grown to be eaten. Oyster gardens get pulled from the water every seven to ten days. The time out of the water is used to clear out small animals, keep oysters from growing through the wires, and dry and clean off plant-life growing on the wires.
Bob Stokes, the director of the Galveston Bay Foundation in Texas, says, “Oyster gardening is as much about education as it is restoration.”

4 . 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!”

5 . Animals, including humans, feel sound as well as hear it, and some of the most meaningful communication happens at frequencies (频率) that people can’t hear. Elephants, for example, use these low-frequency sounds to, among other things, find family or a mate across long distances. Whales do it, too.
But you don’t have to weigh a ton to make a sound. In fact, you don’t have to be bigger than a pea. Consider, for example, the tree-hopper, a curious little animal that lives on the stems (茎) of the leaves. University of Missouri biologist Rex Cocroft has spent much of his time listening closely to tree-hoppers with his team.
The team discovers that all the sounds being heard from tree-hoppers are produced by males. They do it by vibrating (振动) their abdomens (腹部) to make a wide variety of strange sounds. There is almost no airborne sound produced with these vibrational sounds. Cocroft explained, “If a tree-hopper were to stand on your finger and produce a sound, you would feel the vibration but hear no sound.”
They showed that some sounds, not surprisingly, seem to be aimed at attracting females. And some are aimed at other males.
Cocroft explained, “When two males meet each other, or when they are mate-searching on a branch, we’re hearing ‘purring, bdddddrrrr…’ sounds that males give.” Normally, a person couldn’t hear any of this, because the sound travels along the stem, inside it. And that’s how other tree-hoppers detect it.
Cocroft said tree-hoppers have very sensitive legs. And they stand around on stems, which are good at spreading vibrations. So they just use what nature gives them to communicate with each other.
“They have so many different forms of social behavior and grouping,” Cocroft explained. “And once there are animals living in groups, then there will be all sorts of interesting possibilities for communication.”

6 . Every year the start of the Atlantic hurricane season is another reminder for Margarite August that she still doesn’t have a roof.
The 70-year-old retired teacher’s home on the small Caribbean island nation of Dominica was mostly wiped out by hurricane Maria six years ago.
Six years after hurricane Maria, Dominicans like Margarite August still haven’t been able to rehabilitate their homes.
August is not alone. Since Maria, the government of Dominica has built 7,000 new homes—about a quarter of its housing stock-with materials to fight another Category 5 hurricane. They’ve also relocated two communities. But an untold number of the island’s 70,000 or so residents are like August, rebuilding their homes in any way they can afford.
Hurricane Maria is often referred to as a once-in-a-lifetime disaster. Scientists put much of the blame on warming ocean temperatures that could make frequent (频繁的) storms like it.
Maria damaged a terrible 95% of Dominica’s housing stock and 226% of the nation’s GDP. Before the storm, the country’s economy had long struggled since its independence from Great Britain in 1978. Unlike its more famous touristy neighbors along the chain of eastern Caribbean islands it lies on, Dominica is more known for its rugged mountains and jungles (丛林) than white sandy beaches.
The jungle mountains that crash down to the coast are beautiful but disasters visit easily. “I don’t think anybody ever got over Maria,” says Christine John of the Dominica Red Cross. “There are a lot of persons today—if it just starts to rain outside, they get anxious.”

7 . In today’s world, almost everyone knows that air pollution and water pollution are harmful to people’s health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too.
People who work and live under noisy conditions usually become deaf. Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave (织) cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old persons, for these young people like to listen to pop music and most of pop music is a kind of noise. Besides, noise produced by jet planes or machines will make people’s life difficult and unpleasant, or even make people ill or even drive them mad.
It is said that a continuous noise of over 85 decibels (分贝) can cause deafness. Now the governments in many countries have made laws to control noise and make it less than 85 decibels.
In China, the government is trying to solve not only air and water pollution problems but also noise pollution problems.

G.Most injuries happen when people inside buildings try to get out. |
10 . Marine life (海洋生物) in Florida Keys is negatively influenced by two forces: human activity and climate change. The former involves fishing, tourism and diving while the latter causes a large increase in intense hurricanes. Fortunately, when the researchers of Florida Museum of Natural History started looking for sea urchins (海胆) on the ocean floor off the coast of Florida Keys in the summer of 2020, they uncovered their population had relatively been stable since the 1960s.
The researchers visited 27 sites along a 20-mile stretch of coast near Florida Keys looking for tracks that reflected the presence of burrowing echinoids (穴居海胆类动物). “The findings that burrowing echinoids have been highly resilient (有适应力的) against climate change and environmental pollution over the last 60 years was a huge discovery for us.” said study co-author Tobias Grun.
Grun said, “However, we know little about their current distribution, population size, and health. The reason is not the lack of interest by the scientific community but lies in that fieldwork is very expensive.”
As the climate crisis progresses, it’s important to understand why some marine creatures are more resilient in bearing the impacts of a worsening environment than others. Grun said, “Evolution may be at play. Some marine animals are very opportunistic. They can tolerate a wide range of abiotic factors like pH, temperature, and salinity, to name a few.”
Grun added, “At this point, our data show that burrowing echinoids are more resilient than many other marine species and are doing comparatively well. That does not mean that we can push our luck and keep going the way we are right now. Our study provides some hope that these creatures are resilient, but much more work is needed to translate our findings into a larger scale. The reasons for their resilience are also widely unknown.”
