英语听力：自然百科 博茨瓦纳

 Botswana lies in the arid（不毛的，贫瘠的） basins of southern Africa, much of it within the Kalahari（喀拉哈里沙漠） Desert. But in the north, there is an immense oasis（绿洲） called the Okavango Delta¹. Created by the floodwaters of the Okavango River, this inland delta spreads over 6,500 square miles. It attracts a wealth of animal life.

 

Some are specialized² for this waterlogged environment. Hippos bask³ in the sun. Crocodiles wait for the unwary. Lechwe graze in the shallows. These river antelopes⁴ have evolved elongated（细长的） hooves（hoof的复数，蹄） that help them sprint⁵ over marshy⁶ ground. Other animals, more suited for the open savanna⁷, must make do with getting their feet wet.

 

Elephants seem to enjoy themselves wallowing（打滚） in the mud, while cheetahs⁸（猎豹） grudgingly（吝惜地） enter the water in search of prey⁹. Africa’s wild dogs have adjusted well to the Okavango's environment. They'll hunt in wet or dry climates, day or night. They spot a group of lechwe（驴羚）, but the lechwe spot them. The chase is on.

 

The lechwe are too quick. The dogs soon give up. The cheetahs meanwhile manage to drive their prey onto drier land. They would eat well today. For other animals, there are ample opportunities ahead to eat, to grow and to live in the vibrant¹⁰ bounty¹¹ of the Okavango Delta.
