How much sleep do we need? We are all different. A baby needs 16 hours of sleep every day. Children of 6 to 12 years of age need an average(平均)of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep. An adult needs an average of 7 to 8 hours a day. There are some people who need only 3 hours of sleep; others need 10 hours of sleep. After the age of 50, the average sleep time goes down to 6.5 hours a day. We need less sleep as we get older.
About one in three Americans has a problem with sleep. Many of these people cannot fall asleep. The name for this problem is insomnia. Some people say, “I didn’t sleep all night.” But that’s not really true. They may sleep lightly and wake up several times. In the morning, they only remember the time they were awake, so they think they were awake all night.
This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make themselves sleep. Benjamin Franklin had four beds. He moved from one to the other to fall asleep. Mark Twain had a different way. He lay on his side across the end of the bed!

At 9 a.m. on October 15, 2003, our country launched (发射) its first manned (有人的) space-ship, Shenzhou V, into space at Jiuquan Satellite Launch Center in Gansu Province. It took Yang Liwei and his spaceship about 21 hours to circle the earth 14 times. Yang Liwei is China’s first astronaut. He comes from Liaoning Province, and he has been an air force pilot(飞行员) since 1983. He was chosen from 14 pilots after many difficult tests.
The life of an astronaut is hard to imagine for many people. To put on a space suit takes 15 minutes with the help of others. Sleeping in space is not easy, either. He has to sleep in a special sleeping bag on the wall because there is no gravity. Yang can eat chicken and rice. It’s especially made to eat in space but it doesn’t taste nice.
“I’m feeling very good in space, and it looks wonderful here,” said Yang, “I have looked at our beautiful earth and I have recorded all that I have seen here.”
China has become the third country in the world to send a person into space after the former Soviet Union(前苏联) and the United States. China is now planning its next launch. Shenzhou VI will be into space within(在……之内) the next years, it may take three astronauts. We are all proud of our motherland.
