A serious threat to farmers in many parts of the world is erosion. Erosion occurs if a large area of land is cleared of trees and is then badly treated by the farmers. The rain and winds may gradually wash away, or blow away much of the topsoil. When this happens, crops of wheat or corn become weaker and weaker until nothing grows well. If erosion continues, it will turn good land into a desert.

　　　 In the past, when erosion appeared, farmers sometimes moved to a new place to farm. Sometimes they could not move, but continued to try to grow food in the unhealthy soil. This caused them to sink into poverty. Soon some people realized that there was little rich, fertile soil in the world, government began to try to stop erosion.

　　　 One of the first experiments to stop erosion began in the United States in 1933．The experiment was carried out in the area of the Tennessee River. Floods and bad farming in this area had ruined(毁坏)land that had once been rich. As a result, most of the people living around the Tennessee River were very poor.

　　　 The government built big dams across the river and stored the water for use during the dry season when there was no rain. The government workers also helped farmers to fertilize their soil and to learn new farming methods which could stop erosion.

　　　 At the beginning, the farmers were not interested. But soon, good healthy crops began to appear on the land where new methods where used. 　Ten years after the extremely prosperous, the great success of this experiment had led similar projects in the other parts of the world.

Sometimes teens need to have some time away from their families. They may want to move out of the family for a while. Many parents will say no to this demand. But experts say it might be a good idea to let your teens live with a friend or relative.

“It was the break I need at the time,” said Richard Lerner. He is talking about the time he spent living with his grandmother when he was 15.

“It allowed me to be a different person than I was with my parents,” Lerner said. He now heads the Institute for Children, Youth and Families at Michigan State University.

Experts say teens living away from their families can test new ways of thinking and getting along with people. They may see new solutions to problems.

This is different from running away , the experts stress. Runaways are often fleeing(逃避) serious problems.

If there is conflict(冲突) at home, having a teen live elsewhere can benefit other family members. It gives everyone space to develop better relationships.

Some teens who wants some time away from family to attend a structured summer program. Others live for a while with a relative or with the family of a friend.

Joseph Kett teaches history at the University of Virginia in Charlottesville. He says living at home until the late ten years has become the norm(标准、规范) only in recent times.

“In the 17^th century, children were often sent to live in other people’s home when they were about 10 or 11,” he said.

Peter Sheras teaches education at the University of Virginia. He said parents should listen when a child wants to move out. They should try to find out why the child wants some time away. Often, parents can help the child find a safe place to stay during that time. In other cases, they can meet the child’s needs at home.
