Like many nature reserves in Kenya, Borana used to be a cattle ranch (牧场). For thousands of years, cows were     1     center of culture for the Maasai, Samburu, Pokot, and other local groups. When national parks and nature reserves began to     2     (establish) in the middle of the 20th century, these same groups found themselves prevented from grazing (放牧) their animals on land they had depended on for     3     (generation).

Borana now aims     4    (go) into partnership with its neighbors, with programs such as Mazingira Yetu     5     intend to promote environmental protection. Students from nearby communities can spend a day at the nature reserve, go on game drives     6     learn more about various land practices, including water storage, regenerative farming, and tree nurseries. The program was started in 2022, bringing 365 students to Borana, and it     7     (grow) to welcome more than 1, 100 students in 2023,

Borana put all profits (收益) into efforts like this one, and it has made a     8     (different): Last year, tourism produced over $1 million,    9     (lead) to the protection of 28 endangered species, the training of 114 workers, scholarships for 55 students, and drought relief to seven communities. Now there is a growing recognition that change doesn't happen alone, and that long-term efforts to protect wildlife require a     10    (share) purpose across communities and interests.

The day starts early for Zheng Baogang and his tree-planting team. At about 5 a.m., they are on their way to the site of     1     abandoned mine in Huzhou, Zhejiang province.

Since June, they have been working to restore the land to     2     (it)past natural glory. It is the most difficult reforestation project related to the former coal mines and stone quarries in the area in     3     Zheng has participated. The Huzhou mine was put into operation in the late 1980s     4     it is about 200 metres deep now. Today, the entire site for reclamation(开垦)is more than 200. 000 square metres.

    5     (wear)ropes and straps like mountaineers, Zheng and his team took     6     (step)down the cliff to loosen the compacted(压实的)soil and plant trees or grass seeds every day. In summer, the ground temperature can reach over 40°C, while in winter, it is     7     (extreme)cold.

Although the work is     8     (danger)and laborious, Zheng says it is rewarding to see the brown fields turning green. Estimated to be completed by the end of this month, the project will enter a two-year maintenance period     9     (restore)the area’s greenery.

In the past decade, Zheng     10     (help)with such work at over 60 former sites. Some sites are even reviving parklands.

Canada’s national parks are established     1     (protect) and present outstanding representative examples of natural landscapes. These wild places,     2     (locate) in every province and territory, range     3     mountains and plains to forests and lakes. National parks protect the habitats, wildlife and ecosystem     4     (diverse) representative of the natural regions.

Parks Canada is     5     (responsibility) for both protecting the ecosystems of these great natural areas and     6     (manage) them for visitors to understand, appreciate, and enjoy in a way     7     doesn’t compromise their integrity (完整). Parks Canada is working to maintain or restore the ecological integrity of national parks. Maintaining or restoring ecological integrity     8     (be) a challenging task that involves     9     good understanding of the nature of ecosystems and the stresses they face.     10     (addition), it requires cooperation among people whose actions influence the ecosystems.

Dogs may be man’s best friends, but let’s not forget that a faithful fetching stick is a dog’s another best friend if you don’t have a tennis ball at hand.

So when Andrew Taylor noticed that there    1    (be) a lack of good sticks at his local park, he    2     (immediate) determined to take matters into his own hands.

The 59-year-old dad    3    had been chopping (砍) off extra branches from some trees in his yard made a decision    4    (build) a “Stick Library” for all the local dogs.

After    5     (turn) the branches into several dozen conveniently-sized    6    (piece), he put them into a hand-crafted box    7    the words “Stick Library: Please Return” and brought it to the park.

Since Taylor and his daughter hosted a small neighborhood inauguration (开幕) party for the Stick Library, more than 50 dogs and their owners    8     (enjoy) a game of fetch with the sticks.

“As people started to arrive, there was a    9    (disbelieve) of how simple the idea was, but it’s one of those ideas no one had thought of,” said Taylor’s daughter Tayla Reece. “All the dog owners appreciate    10    , as they all have experienced the ‘good stick search’, which isn’t always fruitful. It’s an idea that just makes sense to them.”

During the World Elephant Day on Thursday, Chinese and foreign experts gathered in one online forum(论坛)     1     ( discuss) ways to protect elephants better based on the migration(迁徙) of 15 wild elephants in Southwest China's Yunnan Province. This shows how Chinese people care about the    2     ( protect) of these giant friends.

The 15 wild Asian elephants among    3     one male turned back in July finally returned to their habitat after touring for 17 months in Yunnan Province. The case was taken by the experts as a    4     ( success) example on how to protect and guide the migration of wild elephants.

Zhou Jinfeng, Secretary of the China Biodiversity Conservation and Green Development Foundation, mentioned an idea which focused    5     helping wild animals survive by     6     (reduce) the harm to nature and wildlife in our daily lives.

Zhang Chenglin, Deputy Director of the Beijing Zoo，who introduced some measures taken by Chinese zoos to take good care of elephants,     7     (say) that there were around 150 elephants living in zo0s around China.

“    8     ( human) and animals share nature. To protect elephants     9     (be) to protect our planet. Hope we can work with other countries to protect wild animals."     10     woman wrote on Sina Weibo on the World Elephant Day.

Compared to dogs, cats are usually believed     1    (be) less friendly to humans. However, a new study shows that cats bond to us just as     2    (strong)as dogs.

Researchers at Oregon State University, in the United States, invited the owners of 117 cats to take a test,     3     is often used to test the bonds dogs have with their human     4    (caretaker).

In the six-minute test, cat owners walked into an unfamiliar room with their pets. After two minutes, the owners left the room,     5    (leave) the cats alone, which caused the cats to feel     6    (stress). When the owners returned two minutes later, about two-thirds of the cats came to greet them. The cats then     7    (go) back looking around the room, but still returned to their owners now and then. These cats, the researchers said, saw their owners    8     a source of security in an unfamiliar place. “The more we find out about cats,     9    more we're seeing that they are     10    (society) creatures,” Kristyn Vitale, lead author of the study, said.

A new study found that nearly half of bald eagles    1    (test) across the United States show signs of repeated lead (铅) exposure. Researchers examined the blood, bones, feathers and liver tissue (肝脏组织) of l,210 eagles between 2010 and 20l8.

Lead is a poisonous substance     2     affects the nervous system and interferes (妨碍) with the normal function of nerve cells. Even in low amounts, lead can reduce bald eagles’ ability     3     (fly), hunt and reproduce. In high amounts, lead causes     4    (breathe) difficulty and death.

Bald eagles are one of America’s most celebrated conservation success stories. The birds       5    (remove) from the U. S. Endangered Species List in 2007. But scientists say that high lead levels are still     6     concern. Lead exposure also reduces their ability to face future difficulties, such as climate change or infectious diseases.

“Lead is available to these birds more than we     7    ( previous) thought,” said VinceSlabe, a research wildlife biologist at the nonprofit group Conservation Science Global.

The blood samples from live eagles in the new study were taken from birds trapped andstudied     8    other reasons. The bone, feather and liver samples came from eagles killed by vehicles, power lines or other causes.

The researchers also found higher levels of lead exposure in fall     9    winter. During these months, eagles eat animal remains left by hunters. These remains often contain many    10    (piece) of lead ammunition (弹药).
