In some parts of the world there are large deserts. There are no trees and no water there. Travelers must
take food and water with them. The only animal that can walk through the desert is the camel. It can go
without food or water for a long time and it can carry heavy things. People call the camel "the ship of the
desert". The camel's humps (驼峰) hold fat, and its stomach (胃) holds water in twelve deep pockets. Each
pocket has a mouth which closes, and the food does not mix (混合) with the water. When the camel wants
some water, it can get it out of the pockets. The camel's food is grass and leaves of trees.
