题文
阅读理解。 Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We
spend about a third (1/3) of our lives in sleep. That's about 121 days a year!
How much sleep do we need? We are all different. A baby needs 16 hours of sleep every day. Children
6 to 12 years old 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 night. 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 night.
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 of 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 times they were
awake (醒着), 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 them 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! 1. If you are thirteen years old, you need at least ______ hours of sleep.
