1 . In a world-record effort to help save a valuable sea creature, Australian scientists have released hundreds of baby seahorses into the wild. The tiny seahorses are endangered, and the scientists hope the new seahorses will help their numbers grow.
Seahorses get their name because they look a bit like horses. They aren’t great swimmers, even though they’re fish. They often use their tails to hold onto something in the water. They mostly live in warm, shallow waters around the world. They are often found in coral reefs, in beds of seagrass, and areas where rivers empty into the sea. Seahorses form an important part of the ocean’s food chain. They eat tiny sea creatures and are eaten by bigger sea animals.
Many kinds of seahorses are often threatened by the human actions. Sometimes they’re caught and sold as pets. They are also caught by accident when people are trying to catch other fish.
To begin the project, scientists collected three pregnant seahorses in January. Those seahorses were brought back to the aquarium (水族馆) in Sydney. After the babies were born, the scientists kept them there for five months, feeding the baby seahorses shrimps (小虾) to help them grow strong. Scientist Mitchell Brennan says, “They don’t have a stomach, so they have to eat constantly.”
About a month before the young seahorses were released, the scientists created eight underwater “hotels” for them. The hotels look like cages, providing a safe place for the seahorses to develop. Putting the hotels into the sea early allowed the cages to be covered with small sea life that can help provide food for the seahorses.
This is the fifth time the scientists have released seahorses into the area, and this time was a record. Around 380 seahorses were released. The researchers put tiny tags (标记) under the skin of many of the seahorses to help track them in the future.

2 . Time is running out for coral reefs as the climate gets hotter. So scientists are searching the globe for corals that are better at enduring heat, Now, new research shows how those “super corals” can survive: less roommate drama.
Reefs depend on a crucial partnership between the corals and the algae (海藻) that live in the corals’ tissue, The algae make food for the corals using sunlight and in exchange, get a nice spot to live. But when oceans heat up, that relationship goes bad, and the corals kick the algae out, Without their roommates, corals can die, turning a ghostly white, bleached (白化) color.
Still, some corals seem to resist bleaching better than others, A new study shows that those corals depend on algae that are better at tolerating heat. Researchers hope that pinpointing these abilities will help develop new conservation tools to preserve the world’s reefs as temperatures rise. About 1/4 of all marine life rely on coral reefs in some way, along with half 1 billion people around the world also depend on reefs for their food and livelihoods.
“Heat stress can kill a lot of corals really fast,” says Kate Quigley, a research scientist at James Cook University and the Minderoo Foundation in Australia. “I hope that nature does have some mechanisms to get us through the next few years while we get our act together.”
While the hope is that those algae could also aid in reef conservation in the future, researcher Patrick Buerger says it’s likely that it wouldn’t help all coral species. And even the toughest corals can only endure so much. Currently, the world is on track for just under 3degrees Celsius of warming by 2100, a level that would wipe out nearly all coral reefs.
“The action has to be on climate change,” he says. “This is a short-term solution that might buy some time for corals to adapt. But the main focus has to be on climate. There’s not a silver bullet to the problem.”

4 . Wildlife conservation is the practice of protecting plant and animal species and their habitats. As part of the world’s ecosystems, wildlife provides balance and stability to nature’s processes. Wildlife conservation is aimed to ensure the survival of these species and educate people on living sustainably with other species.
The number of people has grown to more than eight billion today, and it continues to rapidly grow. The economic growth endangers the habitats and existence of various types of wildlife around the world, particularly animals and plants that may be displaced for land development, or used for food or other human purposes. This threat is at top of the list and means natural resources are being consumed faster than ever by the billions of people on the planet. The introduction of invasive species from other parts of the world is another threat to wildlife. Other threats include climate change, pollution, fishing and hunting.
International organizations like the World Wildlife Fund, Conservation International, Wildlife Conservation Society and the United Nations work to support global animal and habitat conservation on many different fronts. They work with the government to establish and protect public lands, like national parks and wildlife protection areas. They help write legislation(法规), such as the Endangered Species Act(ESA)of 1973 in the United States, to protect various species. They work with law enforcement to charge those with wildlife crimes. They also promote biodiversity to support the growing human population while preserving existing species and habitats.
National Geographic Explorers, like conservation biologists Camille Coudrat and Titus Adhola, are working to slow the extinction of global species and protect global biodiversity and habitats. Environmental filmmakers and photographers, like Thomas P. Peschak, are essential to conservation efforts as well, documenting and bringing attention to endangered wildlife all over the world.

5 . Our two-year investigation into caged (关在笼中) tigers in America sent us through 32 US states—with some truly shocking experiences. But as the deadline neared, I still needed a powerful and hopeful image.
When we began our reporting in 2017—Sharon, writing; me taking photos; and our son, NickRuggia, filming—more tigers likely lived in cages in the US than remained in the wild. The number ranged from 5,000 to 10,000, but without strict government oversight, no one knew for sure.
Roadside zoos that allowed tourists to take pictures of young tigers were the main cause of what’s been called a US tiger crisis (危机). Caged cats often ended up in the illegal wildlife trade. Young tigers, parted from their mothers at birth, were fed poorly and touched by hundreds of people. When they grew too big and dangerous to pet at around 12 weeks, young tigers were put on show, or simply disappeared.
While we documented the unpleasant part of this industry, we also wanted to show the good life these impressive animals could have. With two weeks left before my deadline, I headed to the Wild Animal Sanctuary near Denver, where well-cared cats walked freely in their habitat.
There I met Clay, Daniel, and Enzo, three of 39 tigers rescued from an animal park in Oklahoma. These nearly grown cats raced beside our car, which I’d seen only in the wild. It was a hot July day and soon two of the cats jumped into a pool to cool off. The third rested beside them on the ground. I crossed the road to take a picture of them. Then quietly, I came up close, trying not to disturb (打扰) them. I had the shot.

6 . Though you may not know it, about half a billion people worldwide depend on the ecosystems created and supported by corals. And with climate change threatening their survival, marine scientist Enric Sala had an idea that might have seemed impossible.
“We wanted to get into a time machine, go back hundreds of years and actually see a coral reef like they used to be everywhere, before we started exploiting (开发) them, polluting them and killing them all over the world,” Sala said.
The idea was made possible during an expedition that Sala led in 2009. The team travelled to a corner of the South Pacific Ocean and found some untouched reefs.
His team presented their findings to officials in the island country of Kiribati. Then the Kiribati government took steps to protect the waters from fishing and other human activities, but between 2015 and 2016, record levels of ocean warming killed half the coral reefs the team had found.
After hearing that news, they lost hope for the health of coral reefs. But the study continued, and last year, they went in for another dive. Despite the reported conditions, Sala and his team found that the reefs had somehow restored themselves, filled with life and color once more. This resurrection is something that Sala says can be traced to two key factors.
The first is, thankfully, half of the corals had not died, as was previously thought. Despite the rise in temperatures, there were enough surviving corals left behind to help reproduce the reefs.
The second factor is the Kiribati government’s decision to fully protect those waters. “There’s abundant fish species. They eat all the algae (海藻) that would smother (窒息) the corals, making it possible for the corals to come back,” Sala explained.
For him and his team, the rebirth if the coral reefs in Kiribati is a beacon of hope among so much pessimism (悲观主义) surrounding the future of reefs.

7 . We usually divide a year into four seasons. However, in Traditional Chinese Medicine (TCM) theory, there are five seasons — spring, summer, late summer, fall, and winter. Each of the five has many features which guide us to change our habits to keep the balance between our body and the external environment.
Winter in TCM
The ancient Chinese believed that winter is the Yin “阴” season in nature.
In TCM theory, winter is a season to feed ourselves both spiritually and physically. Activities in the season have a turn inwards. For example, we can do more writing, reading and other soul-nourishing (滋养灵魂的) activities. Although energetic exercise should be avoided, it’s important to keep our body healthy with gentle exercise, especially outdoor activities, in which we can get fresh air and sunlight. In addition, we should also go to bed earlier to save more energy.
Foods for winter
The principle of harmony between what we eat and the season is based on hundreds of years of experience in TCM. It suggests that we embrace locally-grown and seasonable foods, which is the way nature intends us to eat. During the winter, there are many foods beneficial to us.
Moods in winter
According to TCM theory, stress, depression and unresolved anger can also weaken our immune system, allowing external factors to affect our body in winter.
| A．Activities in winter |
| B．Exercises in winter |
| C．Most of them naturally grow in this season |
| D．It is inactive, cold and dark, which makes us slow down. |
| E．If you exercise properly in winter, you can enjoy yourself. |
| F．Everyone can enjoy winter if they live and exercise appropriately. |
| G．So, keeping a good mood is especially important in this cold season. |

9 . Boston Marathon runners in recent years may have seen a smiling furry face around the two-mile mark. It’s Spencer, the therapy (治疗) dog, who became known as an unofficial mascot (吉祥物) for the marathon, He’s shown up on the sidelines every year since 2015—rain or shine.
One particularly rainy marathon catapulted Spencer’s fame, In 2018, his owner, Richard Powers, decided to put a bright yellow rain coat on the dog, making him stand out even more than he usually does. Photos of Spencer, who holds a “Boston Strong” flag in his mouth, went viral, and he became an inspiration to runners and onlookers alike, During the marathon, some runners stop in their tracks to take selfies with the dog-the line sometimes growing to 20 runners long.
But in 2020, Spencer was diagnosed with a tumor (肿瘤). His owner was worried, but Spencer is a fighter. He got the care he needed and survived. In 2021, he was back on the course and it was really kind of a miracle and that really hit home to a lot of people.
Unfortunately, Spencer caught another tumor—this one cancerous—and Spencer began chemotherapy. Powers didn’t think his beloved dog would make it out to the marathon of 2022. “Miraculously, he’s still here with us and an even bigger miracle, he was strong enough to go to the marathon,” he said.
After recovering, Spencer was back to work—not just at the marathon—but as a therapy dog, alongside his companion, Penny, who is also a golden therapy dog. Powers takes his two therapy dogs around to schools, hospitals and senior living centers.
“He’s a gift to us and we’re very lucky to have him. He’s too good so we want to share him with as many people as we possibly can. He does make a difference,” Powers said.

10 . Humans have always been working Earth’s land, and they also have always been studying and hoping to work the land of Mars one day.
Planetary scientist Abhilash Ramachandran at the Lunar and Planetary Science Conference reported that Martian dirt may have all the necessary nutrients for growing rice, one of humankind’s most important foods. However, he emphasizes that the plant may need a bit of help to survive in perchlorate (高氯酸盐), a chemical that can be harmful to plants and has been detected on the surface of Mars.
Ramachandran says they want to send humans to Mars, but they cannot take everything there, especially food. He thinks it’s going to be expensive, but growing rice there would be ideal.
Ramachandran and his colleagues grew rice plants in a Martian soil simulant (模拟物). They also grew rice in pure potting mix as well as several mixtures of the potting mix and soil simulant. All pots were watered once or twice a day. The team found rice plants did grow in the artistic dirt of Mars. However, the plants developed slighter shoots and thinner roots than the plants that grew from the potting mix and hybrid soils. The researchers also tried growing rice in soil with added perchlorate. They sourced some rice varieties—modified to stand environmental stressors like drought—and grew them in Mars-like dirt with and without perchlorate. No rice plants grew in a concentration of 3 g of perchlorate per kilogram of soil. But when the concentration was just I g per kilogram, one of the rice varieties grew both a shoot and a root, while another managed to grow a root.
The findings are encouraging, suggesting that by changing to improve with one successful modified gene, humans might eventually be able to develop a rice cultivar suitable for Mars.
