2 . The Vjosa River, one of the last wild rivers in Europe, has been declared a national park by the Albanian government, making it become the first wild river park on the continent.

Home to more than 1,000 animal and plant species, the river flows for 270 kilometers, from Greece, through Albania and into the Adriatic Sea. Giving the credit to no dams or other artificial barriers, it is rich in aquatic species and supports a large number of wildlife species, including otters, the endangered Egyptian vulture and the critically endangered Balkan lynx.

The wild river national park will include almost 13,000 acres of land, crossing most of the body of the country, with thousands of people living in its surroundings. The decision to establish the park is more important than people may realize. For years, the Vjosa’s fragile ecosystem has been under threat: at one point as many as 45 hydropower plants (水 电 站) were planned to build across the region. But thanks to the campaigning by environmental NGOs, the tiny Balkan nation was placed at the forefront of river protection.

Albania’s prime minister, Edi Rama, described the creation of the national park as a “truly historic moment” for nature as well as social and economic development. “Today we protect the only wild river in Europe once and for all,” he said. “This is about to change a mindset. Protecting an area does not mean that you make it in isolation from the economy.” He said national parks attract 20% more   tourists   compared with non-protected areas.

The park will cover the 118 miles of the Vjosa in Albania, three main tributaries (支流), and some land, including areas at risk of flooding. Phase II will add other tributaries. Unlike the IUCN's Wilderness Protected Areas, which limit the number of visitors, it will allow recreational tourism and some   other activities such as local fishing, particularly for 60,000 residents in the catchment.

“We hope it will inspire others to come together to protect the wild places we have left, in a meaningful way,” said Ryan Gellert, Patagonia’s CEO, adding that the park was proof that the “destruction of nature did not have to be the price of progress”.

3 . Set 40 kilometers northeast of the city of Ambatondrazaka, the Zahamena National Park's landscape consists of (……组成) valleys surrounded by a flowing mountain range.

It has an overall land coverage of 64, 300 hectares, but only 42, 000 hectares is open to the public due to strict conservation (环境保护) reasons. It receives an average yearly rainfall level of about 6 feet and experiences frequent rain showers even during the dry season between April and October.

One really interesting thing about the Zahamena National Park is that the unique territory of its highland has paved the way for the development of several ecosystems that exist at the same time in this park. This is the reason why the types of wildlife living in one area are different in another, which makes it quite exciting to explore.

This protected area is divided into two parts, with a separate piece of land in the middle where many small villages are situated. These villages are inhabited (居住) by the members of the Sihanaka and Betsimisaraka ethnic groups.

The Zahamena National Park gets its name from the local Zahana Mena tree, an uncommon type of hardwood that grows in the lower regions of this protected area. It is characterized by its resilient (坚韧的) wood that can be rather challenging to cut, join, shape and carve even with modern tools.

Established as a strict natural highland reserve in 1927 (and one of the first of its kind in all of Madagascar), the Zahamena National Park was officially given its national park status (地位) in 1997 and was eventually opened to the public. Due to its remarkable territory and unique biodiversity, this national park was later listed as a key part of the collective UNESCO World Heritage Site called the Rainforests of the Atsinanana in 2007.

4 . 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.

5 . The following properties which the World Heritage Committee has decided to include on the List of World Heritage are in danger according to Article 11 (4) of the Convention (公约).

9 . One girl is being praised for a letter of apology she wrote to the rangers (园林管理员) at the National Parks Service (NPS). She reportedly _________ a rock home. In expressing her _________, the girl also returned the rock to the park. Later the NPS shared the letter on their Facebook page.

“Dear Park Ranger, I _________ like Tom Branch Falls,” the girl, named Karina, began her letter. “I love it so much that I _________ to take a souvenir home.”

“So I took a rock. I’m _________, and I want to return it,” she said. The heartfelt letter _________ with a postscript (附言) of “also look at the back”—where the girl _________ a picture of Tom Branch Falls. _________ for Karina, the park rangers were _________ by her sincere apology and even __________ back.

“Dear Karina, thank you for returning the rock! It has made its way back to Tom Branch Falls. If every __________ took a rock home, that would __________ 11 million rocks would be gone from the park every year,” the park officials wrote in their Facebook post.

“Now that you know to leave __________ the way you find it, we hope you will help share this __________ with others,” the officials wrote. “It is always a __________ thing to give others the chance to discover something meaningful!”

10 . Scientists from the University of Texas at Austin have finally solved the mystery of a huge fossil(化石）that has been unlabeled and unidentified sitting at a Chilean museum for almost a decade. The relic which looks like a flat football, is the largest known soft-shelled egg from a marine reptile（海生爬行动物）that lived on the earth over 66 million years ago. Measuring more than 11 by 7 inches» it is also the second-largest egg belonging to any known animal, only behind the now-extinct elephant bird.

The rare fossil named " The Thing" was discovered inside a rock formation in Seymour Island off the coast of Antarctica in 2011 by a team of researchers including David Rubilar-Rogers. Over the years, the paleontologist（古生物学者）at Chile's National Museum of Natural History has showed the strange fossil to every geologist that came to the museum. However, no one was able to identify “The Thing's" origin until Julia Clarke» a professor at UT-Austin's Jackson School of Geosciences, visited in 2018.

“I showed it to her, and, after a few minutes, Julia told me it could be an egg!" Rubilar-Rogers said.

To confirm Clarke's suspect, Lucas Legendre, a student at UT-Austin who led the study, examined the fossil under a microscope. Sure enough, he found several layers of membrane（薄膜），confirming that the fossil was indeed a soft-shelled egg, similar to the obvious, quick-hatching eggs laid by some modern-day snakes. “The shell is very thin,” said Clarke.

The fossil's identification led to an even bigger mystery—what animal could have laid an egg this size? After considering several potential parents, the researchers concluded that the egg was laid by an ancient marine reptile like a masseur（沧龙）. The fact that the rock formation where the egg had been found had fossil evidence of baby masseurs and the offspring of other marine animals further strengthened their theory.
