英语听力：自然百科 圣河之旅 The Nile尼罗河—13

Less than a 5th of people here have access to electricity. By damming the Nile, Ethiopia could become Africa’s biggest supplier, providing much needed power for homeS, schools, factories and hospitals. Ethiopia is not alone in wanting a great share of this life changing river. I followed the Blue Nile north to the flat arid⁴ landscape of Sudan. Here, temperature can reach 50 degrees Celsius⁵.

Blessed with the longest stretch of the Nile than any other countries, Sudan is using its waters to turn it into desert green.
