五、(2025·南京市鼓楼区部分学校期中)阅读理解。〔人与自然——自然生态〕
Sunshine, beaches and coconuts(椰子)—these are why people usually go to Hainan. But more than a good place for travellers and foodies, it's also a wonderland of plants and animals.
Hainan Tropical Rainforest National Park has well-kept tropical rainforests. President Xi Jinping visited it in April 2022. The national park covers an area of 4,269 square kilometres. More than 95 percent of the park is forest and the park is also home to 3,653 species(种) of vascular(维管的) plants and 540 species of terrestrial vertebrates(陆栖脊椎动物).
The park is the only home of the endangered primate(灵长目动物)—the Hainan gibbon(长臂猿). It's an uncommon species. Hainan gibbons look like monkeys, but have no tails. They live in the trees almost all their lives. Every morning, they whistle loudly to mark their territory(领地). They eat fruits and leaves from different plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China's achievements in environmental protection.
Not just a sweet home to animals, the park is a "live museum" of amazing plants. More than 400 kinds of plants grow only in Hainan. The Cycas hainanensis(海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, Cycas hainanensis plants over 10 years old blossom(开花) and bear fruit almost every year, thanks to the warm and wet weather.
With so many plants and animals, the biodiversity index(指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable(可比较的) to that of the Amazon rainforest in Brazil. That's why people call the park a treasure for both China and the world.
