青少年是国家的未来,民族的希望,是社会主义革命和建设事业的接班人,因此不仅要求他们要有高尚的品德和渊博的科学知识,还要求他们具备健康的体魄。可是,大量的调查材料证实,近年来,我国广大青少年学生的体质状况和健康水平大大下降,特别是身高、体重,患近视眼的情况尤为严重。 Adolescents are the future of the country, the hope of the nation and successors to the cause of socialist revolution and construction. Therefore, they are required not only to have noble moral character and profound scientific knowledge, but also to require them to have a healthy body. However, a large number of survey data confirm that in recent years, the majority of young students in our country have greatly reduced their physique and health. In particular, height, weight and suffering from myopia are particularly serious.
