In 1620, about half the U.S.A. was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. China doesn’t want to copy the U.S.A.’s example. We’re planting more and more trees. We’ve built the “Great Green Wall” of trees across northern part of our country. The Great Green Wall is 7,000 kilometers long, and between 400 and 1,700 kilometers wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland in the south. More “Great Green Walls” are needed. Trees must be grown all over the world. Great Green Walls will make the world better.

Trees are useful to man in three important ways.
The first important way is that they provide(提供) man with food, wood and the other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It’s not easy for man to live on the earth, either.
The second important way is that trees give us shade(阴凉). On a hot summer day, people are eager(渴望) to have a rest under the tree after they have a long walk. You can imagine how important the shade of a tree is to man and animals.
The third important way is that trees help to prevent droughts and floods(防止干旱和洪水). However, in many parts of the world, man hasn’t realized the third way. They were cutting trees down in large numbers. In the end they find that they have lost the best friends they had.
