听力原文： If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon. Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and bow the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain volumes of a thousand people of different jobs.
Computer technology helped the researchers to get most measurements of the volume of the front and side parts of the brains, which have something to do with intellect and feelings, and decide the human character. As we all know, the back part of the brain, which controls tasks like eating and breathing, does not contract with age.
Contraction of the front and side parts—as cells die off—was seen in some people in their thirties, but it was still not found in some sixty and seventy-year olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction—using the head.
The findings show that contraction of the brain begins sooner in people in the country than in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm worker, bus drivers and shop assistant.

Cheating is nothing new. But today, education and administrations are finding that instances of academic dishonesty on the part of students have become more frequent—and are less likely to be punished—than in the past. Cheating appears to have gained acceptance among good and poor students alike.
Why is student cheating on the rise？ No one really knows. Some blame the trend on a general loosening of moral values among today's youth. Others have attributed increased cheating to the fact that today's youth are far more pragmatic(实际的) than their idealistic predecessors. Whereas in the late sixties and early seventies, students were filled with visions about changing the world, today's students feel great pressure to conform. and succeed. In interviews with students at high schools and colleges around the country, both young men and women said that cheating had become easy. Some suggested they did it out of spite for teachers they, did not respect. Others looked at it as a game. Only if they were caught, some said, would they feel guilty. "People are competitive," said a second-year college student named Anna, from Chicago. "There's an underlying fear. If you don't do well, your life is going to be ruined. The pressure is not only from parents and friends but from yourself. To achieve. To succeed. It's almost as though we have to outdo other people to achieve our own goals."
Edward Wynne, editor of a magazine blames the rise in academic dishonesty on the schools. He claims that administrators and teachers have been too hesitant to take action. Dwight Huber, chairman of the English Department at Amarillo sees the matter differently, blaming the rise in cheating on the way students evaluated. "I would cheat if I felt I was being cheated," Mr. Huber said. He feels that as long as teachers give short-answer tests rather than essay questions and rate students by the number of facts they can memorize rather than by how well they can synthesize information, students will try to beat the system. "The concept of cheating is based on the false assumption that the system is legitimate and there is something wrong with the individuals who's doing it," he said. "That's too easy an answer. We've got to start looking at the system."
Educators are finding that students who cheat ______.
