    People spend almost a third of their lives doing one thing—sleeping. Every year, there is a day for people around the world to celebrate the {#blank#}1{#/blank#} (important) of good and healthy sleep—World Sleep Day.

    Sleep is like food for the brain. Healthy sleep helps the body and brain grow and develop. People of different ages need different amounts of sleep. It is said that eight hours per night {#blank#}2{#/blank#} (consider) the average amount of sleep. For students aged 10 to 17, a healthy amount is about eight to nine hours per night. However, last year, the China Youth and Children Research Center {#blank#}3{#/blank#} (report) that about four {#blank#}4{#/blank#} (five) of middle school students didn't get enough sleep. For some students, they want to sleep early, but they keep {#blank#}5{#/blank#} (worry) about their schoolwork and can't fall {#blank#}6{#/blank#} (sleep) quickly. A lack (缺乏) of sleep can greatly affect (影响) a person's life. Students who don't get enough sleep may get poor grades. They cannot pay attention in class or do well in sports.

    {#blank#}7{#/blank#} (solve) this kind of problem, scientists advise that students should have {#blank#}8{#/blank#} (little) schoolwork and more time to sleep. There are some other ways to help people get enough sleep, such as {#blank#}9{#/blank#} (take) a 20-minute nap (午睡) during the day, trying to go to sleep earlier and so on . Good sleeping habits are also {#blank#}10{#/blank#} (help). For example, try to go to sleep and wake up at the same time every day, even on weekends and during the day.

    Peter was the best table tennis player in his school and hardly ever lost a match. He hated losing anything. When he {#blank#}1{#/blank#} (win), he would feel really good. If he lost, he would feel terrible. It seemed to Peter that losing was the {#blank#}2{#/blank#} (bad) thing in the world.

    A new kid, Albert, came to Peter's school. He was good at table tennis, too. Soon there would be a match {#blank#}3{#/blank#} Peter and Albert. Peter worked hard to get ready for the match, but Albert didn't seem {#blank#}4{#/blank#} (think) much of it. When the match began, Albert was a real player. There was always a smile on his face, while Peter looked serious all the time. Peter thought it was so important to win the match {#blank#}5{#/blank#} he even wanted to cheat(作弊), but he lost in the end.

    "You played very well, Peter. I think we can play again sometime," said Albert. But Peter didn't feel happy and couldn't fall {#blank#}6{#/blank#} (sleep) that night.

    One day, Peter saw Albert playing basketball. {#blank#}7{#/blank#} he lost again and again, the happy smile never left his face. Peter found Albert was great at table tennis， but bad at basketball. However, he enjoyed {#blank#}8{#/blank#} of them.

    Whether he won or lost the game, Albert enjoyed it. Peter came to realize that enjoying a game was much more important than winning or {#blank#}9{#/blank#} (lose) it. He felt {#blank#}10{#/blank#} (happy) than ever before.
