Chinese writing is one of the world's greatest writing systems． It is more w（1） in use than alphabetic（字母的） writing systems． More than half of the world's books are written in Chinese， including historical writings and novels， along with writings on government and law．
At the beginning， written Chinese was a picture﹣based 1 （2） ． It dates back several thousand years to the u（3） of animal bones and shells on which symbols were carved （刻） by ancient Chinese people．Some of the ancient symbols can still be seen in t （4） _ hanzi．
By the Shang Dynasty， these symbols had become a well﹣developed writing system．Over the years， the system developed into different forms， as it was a time when people were d（5）
geographically， leading to different dialects（方言） and characters． This， however， c（6） under Emperor Qishihuang of the Qin Dynasty．
Emperor Qinshihuang united（统一）the seven major states into one country where the Chinese writing system began to develop in one direction． That writing system was of great i（7） in
uniting the Chinese people and culture． Even today， no matter where Chinese people live or what
dialect they speak， they can all still c（8） in writing． Written Chinese has also become an important method to c （9） China's present with its past． People in modern times can read the classic works which were written by Chinese in ancient times．
Today， Chinese writing system is still an important part of Chinese culture， As China plays a g（10） role in the world， an increasing number of international students are beginning to appreciate（ 欣赏） China's culture through this amazing language． Written Chinese spreads Chinese culture wherever it goes．
Though times have changed， falling asleep in class is still a common occurrence（常事）among teenagers．
Why do students sometimes fall asleep in class？ An obvious reason is lack of sleep． However， there are also causes for getting too little sleep．
Homework is a daily occurrence for most students， one that can take three
to four hours per night． A teenager who wants to be able to take part in
any activity besides homework must stay up late to fit everything in． Club
activities， sports， computer﹣game playing， and TV viewing，for example，all contribute to （促成） teens having less time for both homework and sleep．Sometimes teens lack sleep because of after﹣school jobs that are taken on to earn extra money for college， family expenses， or simply for clothes．
Physical problems are another factor that can cause students to fall alseep in class． For example，
insomnia， which may keep a student up at night， causing exhaustion（疲惫不堪）during class hours，
is a serious problem that may require medical attention． Medical evidence also supports the idea that each person has a body clock that helps to decide his or her sleep pattern． Unluckily， these body clocks do not always work according to school timetables．
The effects of falling asleep in class can be quite serious． First of all， sleeping in class is not a good way to endear（使受喜爱） yourself to teachers． In addition， it is highly possible that other students may make jokes about those who sleep in class． However， the most harmful effect of sleeping in class is missing out on important points． In the long run， sleepers may end up failing classes．
Since teens are probably not going to deal with the problem， falling asleep in class will probably remain an all﹣too﹣common occurrence． It will continue until more teens find a way to balance their personal and social lives with school and work， while still finding enough time to sleep．
