【BBC地球脉动】雄伟高山 18

英语自学网

A giant panda nurses a tiny week old baby. Her tender cleaning wards off infection. She won't leave this cave for three weeks, not while her cub is so utterly helpless. Progress is slow for milk produced on a diet of bamboo is wretchedly poor. Four weeks old and the cub is still blind. Its eyes do not fully open until three months after birth, but the chances of the cub reaching adulthood are slim. The struggle of a giant panda mother to raise her cub is a touching symbol of the precariousness of life in the mountains. On the highest summits of our planet nothing can live permanently. The highest peak of all, Mount Everest, five and a half miles above sea level and still rising - the roof of our world.一只大熊猫正在给一只一周大的幼仔喂奶。它温柔地给小宝宝清洁，防止宝宝染病。它一连3周都不会离开。因为小宝宝太小太弱了。小宝宝长得很慢，因为竹子的营养非常少。4周过去了，小家伙还没有睁开眼睛。它要等到3个月以后才能完全睁眼，熊猫幼仔的存活率很低。母熊猫艰难喂养幼仔的动人过程充分发映出山地生活的艰难。在我们这个星球最高的山峰上，没有生物能够在那里长期生存。世界最高峰珠穆朗玛峰还在上升。它是世界的屋脊。
