丹尼斯是美国野生动物保护协会的成员,为了搜集狼的资料,他走遍了大半个地球,见证了许多狼的故事。他在非洲草原就曾经目睹了一次狼和鬣狗交战的场面,至今难以忘怀。那是一个极度干旱的季节,在非洲草原许多动物因为缺少水和食物而死去了。生活在这里的鬣狗和狼也面临同样的问题 Dennis is a member of the Wildlife Conservation Society of the United States. In order to collect information on wolves, he traveled over most of the earth and witnessed the stories of many wolves. He once witnessed a battle between wolves and hyenas on the African grasslands. It has never been forgotten. It was an extremely dry season. Many animals in the African grasslands died because of lack of water and food. Dogs and wolves living here also face the same problem
