三、还原信息
There are deserts in many countries. (1)
A
This is a serious problem because deserts destroy farms and land where animals live. When people cannot grow food or find animals to eat, they have to leave their homes. Wind can move sand away from deserts and into useful land. When there is no rain for a long time, plants die and deserts grow.
However, humans can also cause deserts to grow. One way is when people cause too much air pollution, which can make an area hotter. For example, cars and factories produce greenhouse gases that make the earth warmer. Hotter weather reduces rain as well. (2)
C

Besides, having many animals can harm the land. When large animals walk on the earth too much, they turn it into dust (灰尘). The wind blows the dust away. But trees can stop the dust from flying farther. (3)
B
When people cut down too many trees, less water stays in the ground, and the earth is destroyed.
(4)
E
So in order to stop deserts from growing, people must take action and think of ways to treat the land better. But what will the desert be like? We are all looking forward to its change.
A.In some places, deserts are growing.
B.Trees can also help hold water in the ground.
C.This makes the land dry and turns it into desert.
D.Animals without water will go crazy and hurt people.
E.All of these things can speed up (加速) the growth of deserts.
F.Deserts sometimes can be good for both animals and people.
