Camels keep fat in their humps. In the desert.there is not a lot of food. Camels use the fat in theirhumps for food, so they can survive for a long timewithout eating. As camels use the fat, their humps getsmaller.
In Egypt, camels have been used for long trips forover 3,000 years. It is really a long time!
中文大意
駱驼的驼峰里储藏着脂肪。在沙漠中没有充足的食物,骆驼就消耗驼峰里储藏的脂肪充当食物。这样,就算很长时间不吃东西,骆驼也不会饿死。当骆驼使用驼峰中的脂肪时,驼峰就会变得越来越小。
3000多年来,埃及人一直把骆驼当做长途旅行的交通工具。这真是有很长时间了。
