1 . The black cloud rising every day at sunset in the Chihuahuan Desert went largely ignored for thousands of years. Native Americans noticed it, but did not track its source. Cowboys thought the cloud was smoke pouring from the earth, and avoided it.
In June of 1901, however, a teenage cowboy named Jim White happened to see the large, black cloud. He was curious and went to investigate. Instead of finding a volcano, as he had imagined, he discovered something equally amazing. It was a big mass of bats. Two days later, he returned with a lantern to explore further. It took him so long that his lantern went out. He managed to refill it with just enough oil to find his way back to the entrance.
The next time Jim White went to the cave, he brought a friend and supplies. They explored for three days and returned with descriptions that were so fantastic that few people believed them. The cowboys on nearby farms and the people in the tiny town of Carlsbad treated Jim’s stories as tall tales and nothing more.
After years of exploring the caves and finding no one to believe his stories, Jim White decided to create his own tourist attraction. He established trails (路线) along the paths he had found. One day in 1915, two men asked Jim for a tour. After seeing the caves, the men returned with a professional photographer named Ray V. Davis. Local doubts were finally put to rest by the photographs of the hidden beauty that Jim had discovered. All 13 locals of Carlsbad finally took a tour of the caves, which came to be known as Carlsbad Caverns.
In 1923, the government sent an official named Robert Holly to tour the caves. Later that year, the caves were stated a national monument (古迹), and in 1930 they became a national park. Jim White lived to see the Carlsbad Caverns become world-famous. Today, tourists can hike to and tour some of the 100 known caves in this huge natural wonder, thanks to the cowboy from New Mexico.

3 . John “Charlie” Veron-widely known as “the Godfather of Coral Reef (珊瑚礁)”-is a celebrated expert who has personally discovered nearly a quarter of the world’s coral species and has spent the past 45 years diving Australia’s Great Barrier Reef. But now the 73-year-old is raising the alarm about its future. The Great Barrier Reef, one of the natural wonders, is 2, 300 kilometers long and is the only living organism that can be seen from space. It is considered a World Treasure Site due to its biodiversity (生物多样性)with 30 species of whales, dolphins and sharks. Within the reef itself, there are also a number of tiny organisms and fishes.
However, its health is threatened. After the recent mass bleaching (白化)events, Veron dived in many areas of the Great Barrier Reef to see the damage for himself. “I was seeing and feeling it and it was absolutely shocking, ” he says.
Veron says the mass bleaching events in the past few years-and the possibility of losing one of nature’s greatest treasures-were a wake-up call for the world in the wider battle against climate change, which, together with the rising sea temperature, is considered the greatest threats to the reef.
Fortunately, earlier this year, the Australian government announced nearly 400 million dollars in new funding towards scientific projects designed to help the reef.
There has been criticism in Australia about the slow process for the funding. “It won’t be wasted, though,”Veron says. “As scientists will be able to create a sort of seed bank to protect the species until the climate is good enough to rebuild the reef. What the scientists hope to do is to help nature along a bit after the big carbon dioxide increase is over and it starts to come down.”

6 . It’s safe to say Yellowstone National Park is still looking good at the ripe old age of 150. The park, which stretches into Wyoming, Montana, and Idaho, is known for its unique natural scenery, bountiful wildlife, and deep history. It also helped usher (引领) in the broader national park movement in the U.S., according to Chuck Sams, the director of the National Park Service.
“We now celebrate something much bigger than the park itself —the beginning of the national park idea, an idea that spread through the country and around the world, inspiring governments to protect natural and cultural treasures ‘for the benefit and enjoyment of the people,’” he said in a statement.
Yellowstone is home to the largest concentration of mammals in the lower 48 states. Bears, wolves, coyotes, moose, and a large population of small animals can be found in the park. It’s also the only place in the U.S. where bison (野牛) have lived continuously since prehistoric limes. It was looking risky for a period in the 1900s, when die animal was hunted down from a previous high of tens of thousands to less than two dozen. This bison conservation effort continues to this day.
Yellowstone shut its gates in March 2020 due to coronavirus concerns and remained closed for nearly two months. But the park broke attendance records after it reopened. The park reported 4.9 million recreation visits in 2021 — up 28% from 2020 and making it the busiest year on record, July 2021 was die most-visited month in Yellowstone’s history and the first lime visitation exceeded l million visits in a single month. It’s Yellowstone’s natural beauty and deep history that brings millions of visitors each year.
“Yellowstone’s 150th anniversary will be an important moment in time for the world,” said Yellowstone Superintendent Cam Sholly. “It’s an opportunity for us to reflect on the lessons of the old days while focusing our efforts to strengthen Yellowstone and our many partnerships for the future.”

9 . Humans are responsible for 25% to 40% more of the total share of methane emissions(甲烷排放)than previously estimated, according to a new study in Nature.
Methane is one of the most powerful and effective greenhouse gases: about 28 times more effective than carbon dioxide at trapping heat in the atmosphere. It's responsible for about a quarter of global warming. It's produced naturally by animals, volcanoes, and wetlands, but it's also a byproduct of oil and gas production. It's this last form of methane that the study focused on.
Researchers used ice core measurements from Greenland from 1750 to 2013, plus previous data from Antarctica. They melted the ice to let the small quantities of ancient air trapped inside come out. These act a bit like time capsules,allowing us to learn about the methane in the atmosphere at the time. They used carbon-14, which comes from living things, as a substitute(替代物)to determine whether the methane they found came from biological sources. Until 1870, around the time when we started using fossil(化石)fuels, almost all methane came from these sources. After that, there was a rise in methane that didn't have any carbon-14, from ancient fossil sources in which carbon-14 had disappeared. That allowed the researchers to compare natural methane with methane caused by human activity.
If more methane is created by humans, there's an even bigger opportunity to control how much we release. Methane stays in the atmosphere for only a decade(compared with 200 years for carbon dioxide). So efforts to cut methane, which mostly comes from the production and transportation of gas and oil, could bring great benefit right away.
1. Which methane source does the study focus on?| A．Animals. | B．Wetlands. | C．Volcanoes. | D．Fossil fuels. |
| A．Methane comes mainly from animals and wetlands. |
| B．There is more methane than carbon dioxide in the air. |
| C．Fossil fuels have been used about a century and a half. |
| D．Methane will remain permanently in the atmosphere. |
| A．Optimistic. | B．Skeptical. | C．Disappointed. | D．Unconcermed |
| A．Fossil Fuels Cause Global Pollution |
| B．Humans Produce More Methane than We Thought |
| C．Methane Is the Biggest Cause for Global Warming |
| D．Carbon Dioxide Has Less Impact on Climate than Methane |
