9.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.
But the scientists say many children have missed out on 4,500hours 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!

分析 多达65%的孩子们没有足够多的睡眠,这可能导致他们在学校里紧张、反应迟钝"研究人员说.
那么年青人每天晚上应该睡多长时间呢?答案是8到10个小时.如果你晚上没有得到足够的睡眠,你第二天将没有充足的能量.
但研究者说许多孩子到了七岁时已经错过了4500个小时的睡眠时间.他们说孩子们没有充足睡眠,是因为他们在自己的房间有电视和电脑,繁忙的父母晚上没有给年幼的孩子读一些东西.传统的"睡前故事"可以帮助孩子放松和更好入睡.孩子在自己的卧室看电视电脑就有可能没睡好觉,并且睡眠时间少于八小时.甚至少睡一个小时就意味着孩子们在学校做的更少一点.
德国科学家认为在你熟睡的时候,你的大脑仍在工作.证明他们是正确的,他们分两组人来解决一个难题.一组人去睡觉,另一组人保持清醒.结果呢?在睡觉的人解决问题更快,说明当人们都睡着时它们的大脑一直试图找到答案.所以,确保你今晚有足够的睡眠,明天你会处于最佳状态!
