Up to 65% of children don't get as much sleep as they should do, and this can make them nervous and slower at school, scientists say.
So how long should young people sleep each night? The answer is between eight and ten hours. If you don't get enough sleep at night, you'll have less energy the next day.
①But the scientists say many children have missed out on 4, 500 hours of sleep by the time they are seven years old. They say that children miss sleep because they have TVs and computers in their rooms，and busy parents don't read to their younger children at night any more. The traditional "bedtime story" helps children to relax and fall asleep peacefully. Children with TVs and computers in their bedrooms are more likely to sleep badly, and to get less than eight hours' sleep. Even losing one hour's sleep a night can mean that children do less well at school.
German scientists think that your brain(大脑)keeps working while you are asleep.②To show that they were right，they gave two groups of people a problem to work out. One group went to sleep, and the other group stayed awake. The result? The people who slept worked out the answer
more quickly. This showed that their brains had been trying to find the answer while the people were asleep. So, make sure you get enough sleep tonight, and you'll be at your best tonight, and you'll be at your best tomorrow!

If you've ever stayed up late and then got up early the next day, you know what it's like to not get enough sleep. It's a very uncomfortable feeling. In fact, scientists have long believed that sleep is like food ——if we don't get enough of it, we might get sick or even die. But now they are starting to wonder just how much sleep we need.
Researchers from London recently did a study on fruit flies （果蝇）. They found that flies that slept for very short periods of time —— about 72minutes a day —— still lived about as long as flies that slept for longer time. One of the flies slept for just 4 minutes each day. This has led the researchers to wonder if sleep is less necessary than we thought before.
Humans are very different from fruit flies. Sleep is when our bodies do a lot of work, for example, repairing tissue（组织）and growing muscle （肌肉）.Sleeping allows our bodies to get a good rest.
But can we really die from not sleeping? No human has died so far from staying awake for too long. The world record for sleeplessness is held by Randy Gardner from the US, who stayed awake for 11 days and 24 minutes in 1964. However, Gardner did experience serious side effects （副作用）.
Scientists have not yet found any animals that don't sleep at all. Even animals that only sleep for short periods are not completely sleepless. This suggests that a short sleep is necessary, even in short-sleeping animals, according to a German scientist.
1.What does the study on fruit flies show?
A.Fruit flies sleep less than humans do.
B.Flies need 72 minutes of sleep every day.
C.Sleep is as necessary for animals as it is for humans.
D.Getting less sleep doesn't seem to influence how long flies live.
2.The purpose of Paragraph 3 is to________.
A.describe how much sleep humans need B.explain why sleep is important to humans
C.list the differences between humans and flies D.show the similarities between flies and humans
3.What do we know from the passage?
A.Sleep may not be so important as we think it is. B.Humans need more sleep than animals.
C.Sleeplessness can lead to death. D.Not all animals need sleep.
4.What’s the best title for the passage?
A.How Much Sleep? B.Die Without Sleep.
C.Wonders of Nature. D.Get Enough Sleep.

If you get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle （吹口哨）three times. Stop. Then shout or whistle three times again. Any signal（信号）for three times is a call for help.
Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house with branches（树枝. Make yourself a bed with leaves and grass.
When you need some water, you have to leave your little branch house to look for it. Don’t just walk away. Pick off small branches and drop them as you walk in order to go back again easily. When you are lost, the most important thing to do is to stay in one place.
