What's the life in the desert（沙漠）like? You may think there is only sand（沙子） in the desert of the world, but it's not true. In the desert, there is a little rain, but it's not enough for most plants. Still we can see some plants live in the desert.
There is water in some places of the desert. We call these places oases. In the oases, there are villages and towns. People grow many kinds of plants in the fields there. People also live outside the oases. They have camels（骆驼）and other animals. These animals do not need much water. The animals are useful to the desert people in many ways. They eat the meat and drink the milk of the animals. They use the camels for carrying water, food and something else（其他的）. The desert people have to keep moving from place to place. They must always look for grass or desert plants for the animals. When there is no more food for their animals, they move to another place. The desert people are friendly. They want to help the people in trouble（陷入困境）and give them food and water.
