河北省邢台市第一中学2017-2018学年高二上学期英语第一次月考试卷
Feifei,an 11-year-old boy from Xuzhou,Jiangsu Province,suffered from a sudden acute eye disease which has almost led to blindness.The disease was caused by excessive（过度的）eye fatigue（疲劳）during the winter vacation, during which he played computer games for continuous 10 days and nights.
Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products. This is followed by a series of health problems,with the most typical case being myopia,or nearsightedness.
According to the latest research report released by the World Health Organization (WHO),the myopia rate among Chinese teenagers ranks first in the world—70 percent of high school and college students.The rate is nearly 40 percent in primary school students,while it is only 10 percent for their peers in the United States.
There are at least 10 million people in China with severe myopia,and they are likely to get pathological（病理性的）myopia in middle age.Pathological myopia can't be treated with glasses or surgery,and it is one of the biggest factors that lead to blindness,Xu Xun,director of the ophthalmology（眼科学）department at Shanghai General Hospital,pointed out.
Experts explain that two major factors lead to the high rate of myopia among Chinese people.One is high academic pressure,and the other one is excessive use of electronic devices over a long period of time.Genetics,on the other hand,are not the main reason,as only 20 percent of Chinese people had myopia in the 1960s.
"Teenagers are now faced with severe academic pressure,which means they often study without natural light. This increases their risk of becoming nearsighted,"Xu said.
Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process.
