一篇任务型 Did you sleep the day away on March 21?Well
you should have done that because it was World Sleeping Day.This is the one day of the year when people around the world care about their sleep and ask themselves a lot of questions about sleep.
Why do we need sleep?Nobody as yet can give a perfect answer to this question.However,tests have shown that lack(缺少)of sleep over about four weeks leads to a strong drop in body temperature,great weight loss and finally sickness.
Different people need different amounts of sleep.Eight hours a night is considered the average amount of sleep.For teenagers the least number of sleeping hours advised by doctors are ten hours for primary school students,nine for junior highs and eight for senior highs.
Some people seem to get along just fine with very little sleep at night.Leading American scientist Thomas Edison said that sleep was a waste of time.He did,however,take naps during the day.On the other hand.Albert Einstein,another great scientist,said he needed at least ten hours' sleep a night.
Here are some of the most useful suggestions,for a good night's sleep:
Go to bed at the same time.
Use your bed only to sleep.
Don't exercise in the evening.
Keep the bedroom dark and quiet．
Drink a glass of milk before sleep.
Stop looking at the watch while you can't sleep!

你是否把三月二十一日睡过去了?你应该那样做,因为那天是世界睡眠日.每年的这一天,世界各地的人们都关心自己的睡眠（问题）并问自己有关睡眠的许多问题.
我们为什么需要睡觉?至今没有人能给出完美的答案.测试表明：超过四周以上缺少睡眠能导致体温大幅下降、体重大幅减轻并最终导致生病.
不同的人需要的睡眠时间各不相同.八小时睡眠是平均值.对青少年来说,医生建议小学生每天至少睡十个小时,初中生睡九个小时,高中生睡八个小时.
有些人晚上睡得极少也过得去.美国科学带头人托马斯 爱迪生认为睡觉是对时间的浪费.然而,他在白天经常小睡一下.另一方面,另一个伟大的科学家阿尔伯特 爱因斯坦说他每天晚上至少需要睡十个小时.
以下是对良好睡眠质量的一些有用的建议：
每天在同一时间段睡觉
床只做睡觉之用

by the way ,you are so mean.so many translations and no extra scores!ps,counting sheep will do no good to Chinese to help us sleep since it will not remind us "sleep".it only works when we say sheep in English .Since "sleep"and "sheep"have the similar pronouciation and say sheep will do some positive implication to ourselves .just like hypnosism.
