Various animals are respected and even worshipped(崇拜)in different cultures．In Hinduism, for example, cows are valued for their gentle nature．However, in ancient Egypt, crocodiles(鳄鱼) were regarded as living representations of the god Sobek．During the serious drought in the 15th century, the Mossi were led to an undiscovered pond by the crocodiles．This not only allowed the Mossi to survive, but also led to the founding of the village Bazoulé．As the villagers owe their survival to the crocodiles, they now care for and live side by side with them．The villagers even bury the crocodiles and hold funerals for them after their death．The crocodiles are not only regarded as protectors of Bazoulé，but also fortune-tellers that give best wishes to the villagers．It seems that the worship of the crocodiles has paid off．For over 70 years, there has never been a death from a crocodile attack in Bazoulé．It’s normal for women to wash theirclothes in the water and gather plants nearby．And it is also normal to see children playing around the water where the crocodiles live．Naturally, this strange relationship between the villagers and crocodiles has attracted a lot of attention．Tourists from all over the world come to the village, hoping to catch sight of this unlikely bond between humans and crocodiles．Visitors have the opportunity to buy a chicken, with which they can attract the crocodiles out of the water．You can pose for pictures, and if you’re brave enough, you can sit on a crocodile’s back just like the local children usually do．The village is trying to develop its tourism, but unfortunately, it was found to be threatened by global warming．Lower annual rainfall means that the pond will vanish one day．Perhaps the legends are true, and when this happens，the crocodiles will lead the Mossi to a new water source．本文是一篇说明文。
