Babies sleep about eighteen hours a day.Mrs. Thatcher and Napoleon both said they only needed to do it three or four hours a night.No one can live without sleep.But how much do we really need?
Research(研究)by the National Sleep Foundation in Washington says that we all need eight hours’ sleep every night.Scientists have found that people who sleep for less than six and a half hours a night are more often ill than people who sleep for eight hours.Going without sleep also increases(增加)the chance of serious illness.“Workaholics(工作狂)”who sleep for less than five hours often die young，and do less well at work.
The scientists found that adults(成年人)usually sleep for seven hours a night，with 32% sleeping less than six hours.
It also says that the idea that we need less sleep as we get older is completely untrue.“People have no idea how important sleep is to their lives.”Dr. Thomas Roth，director of the Foundation says.“Good health needs good sleep.”
“But not too much of it.”says Professor Jim Horne of Loughborough University,“sleep is like food and drink，”he believes，“you would always like to have a little bit more，but that doesn’t mean you need it.”Professor Horne studied a group of people who could spend as many hours as they wanted in bed，after ten hours they didn’t find it any easier to get up in the morning.And people who sleep for more than nine hours a night die younger than people who usually sleep for seven or eight!

Music is an international language. Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class，after class，and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street. Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports，the weather，politics，and activities of the American people. Most of the radio broadcast is music.
Popular music singers make much money. They make a CD or tape which radio stations use in every state. Once the popular singer is heard all over the country，young people buy his or her tape. Some of the money from these tapes comes to the singer. Wherever the singer goes，all the young people want to meet him or her. Now the singer has become a national star.
