　　"No," Andrew said.

　　"Then what about one dollar?" the old woman asked. "I can buy an orange."

He heard the two men behind him, getting nearer, and at the same time he heard a voice in his ear. It told him to go to the right, and he did so. He ran on and on and came to a small hotel.

Today the forests have almost gone. But too many trees are still being cut down. There is a lot of sand left. China doesn't want to follow the U. S. A.'s example. So China has built a new Great Wall across the northern part of China, This time, it is a "Great Green Wall" of trees, millions of trees. The Great Green Wall is 7,000 kilometers long, and between 400 and 1,700 kilometers wide. The Green Wall will stop the wind from blowing the earth away.
