Do you sleep eight hours every night？In fact，more than 300 million Chinese don't have enough sleep. （1）About 85% of the teenagers sleep less than six hours every night.Why does this happen？First，teenagers don't get enough sleep because of heavy schoolwork. （2）他們每天必須花大量時(shí)間完成作業(yè)。But after long hours' study，some of them may find it is difficult to fall asleep quickly when they finally lie on bed.A study showed that 43%of the young people take medicine（吃藥） to help them sleep. （3）"Although I know it is not good to take medicine，I have no better ways." said Su，a 14-year-old middle school student.
    Besides，overuse of electronic devices（電子設(shè)備） and lack of（缺乏） exercise also make difference.Many students see using the Internet as way to relax，（4）但是放松的最好方式是通過(guò)鍛煉。The overuse of the Internet will only bring more serious problems to both their mind and body.（5）Everyone should know the importance of getting enough sleep.Taking medicine helps sometimes，but parents should try to find out why their children have sleep problems and help them out as soon as possible.
