学期的一至三周内学生中一些症状会明显增多,应引起注意。它主要表现在下肢关节扭伤和肌肉拉伤增多;其次是患感冒、咽炎、发烧等常见疾病的人数增多;另外,还表现在学生精力不充沛,上课注意力不易集中,纪律松懈等。推究其原因可发现:随着电视机的普及、生活条件的改善,假期中学生户外体育活动减少,从而导致体质下降,适应能力降低。另外,假期中电视看到很晚,养成早晨睡懒觉的坏习惯;开学后仍贪恋电视,早晨虽勉强起床,但精力不充沛,上课注意力不易集中,影响学习。
Within one to three weeks of the semester, some of the students’ symptoms will increase significantly and should be noticed. It is mainly manifested in the increase of lower limb joint sprains and muscle strains; followed by the increase in the number of common cold, pharyngitis, fever and other common diseases; In addition, it also shows that students are not full of energy, school attention is not easy to concentrate, loose discipline and so on. The reason for the investigation can be found: With the popularization of televisions and improvement of living conditions, outdoor sports activities for middle school students are reduced during holidays, resulting in a decrease in physical fitness and a decrease in adaptability. In addition, during the holiday season, the TV saw late and developed the bad habit of sleeping late in the morning. After starting school, she still fell in love with the TV. Although she barely got up in the morning, her energy was not sufficient, and her concentration in class was not easy to concentrate on learning.
