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.
But 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
were 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. To 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!

are those who not only get high marks, but also follow the rules and the behavior standards (标准) for
middle school students. Here are some of the new rules and standards.
Tell the truth. Have you ever copied someone else's work on an exam? If you have, then don't
do it again! That's not something an honest student should do. If you have played computer games for
two hours in your room, don't tell your parents you were doing homework.
Learn to be loving and caring. Good students love animals and care for other people.
Learn to work together with others. It would be more fun when more people work together. Did
you quarrel with your teammates when your basketball team lost? Only working together can make your
team stronger. Be friendly to the people you are with. Try to think of others, instead of only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Perhaps you'll
discover Earth Ⅱ someday. Don't look down on new ideas. Everyone's ideas are important. You
should welcome them, because new ideas make life better for everyone.
Use the Internet carefully. The Internet can be very useful for your studies. Some websites (网站)
on the Internet aren't for kids, so make sure to visit the Web pages that are good for you. You can
use the Web for fun or homework. Can't you find any good websites for children?

C. how they can get high marks
D. what is right and what is wrong
