Do you know why you sleep? You may think it’s because you’re tired. Or perhaps you’ve been told sleep is good for you. Yet no one knows exactly why or how people sleep.
Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes each, sleepers’ eyes made rapid movements, as if they were watching something. He called these periods REM sleep, for Rapid Eye Movement. Periods when sleepers’ eyes did not move he called non-REM sleep.
Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers’ pulses(脉搏)went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, REM sleep is a time when the body is hard at work. Scientists still don’t know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time in REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day’s garbage.
One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most major car accidents happen during the early morning hours, when people are sleepiest.

If you’re into sports, you’ve seen it happen—tennis players jump over the net to shake hands after a hard match; football players exchange clothes after 90 minutes of knocking each other around; even boxers touch gloves at the beginning of each round. Players in every event, from spelling bees  to golf, act in this way. It’s all part of sportsmanship, a great tradition in sport and competition. It means playing and being calm all through the match.
Everyone feels great when they win. In the last few years, you might see some players celebrate a goal with a long victory dance or talk big about their ability. However, it’s always hard for people to say in public that they made a bad play. Good sportsmanship is what they really need. It’s the golden rule of sports.
Good sportsmanship means that you play by the rules, talk politely to everyone during games and stay cool even when you lose the game. At the school sports meeting, for example, it’s more important for you to know how to work as part of a team and cheer your teammates on. That may help you enjoy more success at your future work. In competition—as in life—you may not always win, but believe me, sportsmanship will help you get through, and there is always the next match.

Long long ago a man went to India and he had never been there before. When he got there, he saw a lot of fruit, but much of it was expensive because they couldn’t grow much because there was little water. Finally he saw a big basket of some very red and long fruit. And it was the cheapest in the shop.

So he went up and asked, “How much each kilo?”and the shop keeper said, “Two rupees(卢比). ”Two rupees in India was nothing. So he bought a whole kilogram of the fruit and started eating it. But after he ate some of it:oh, my god!His eyes watered, his mouth watered and burnt, and his face became red. He jumped up and down, saying, “Ah!Ah!Ah!”

But he still continued to eat the fruit!Some people who were looking at him shook their heads and said, “You’re crazy, man. Those are chilies(辣椒)!You can’t eat so many!People use them as a condiment, but only a little bit to put into food for taste. You can’t just eat them like that. ”But the silly man said, “No, I can’t stop!I paid money for them, and now I’ll eat them up. It’s my money!”

And you think that man was silly, right?We sometimes do a lot of things like that. We spend money, time or effort doing something. And even though it’s been a long time, hard experience tells us it won’t work, and we know there’s no more hope, we still continue just because we’ve put money, time, effort and love in to it. Just like the man who ate the chilies and felt so bad but couldn’t stop because he didn’t want to waste the money he’d paid.

So even if you’ve lost something, let it go and move on. That’s better than continuing to lose.

1.The man chose to buy the red and long fruit only because  .

A.he hadn’t eaten it before                B.he was hungry

3.Which of the following sentence is TRUE?

A.The man went to India to buy fruit.

B.The man didn’t want to waste money.

C.The man bought the fruit because it was expensive.

D.India can grow a lot of fruit.

4.From the passage, we can learn that_________.
