一、必要性1.学生的身体需要随着我国生活水平的不断提高,青少年进入青春期的时间已比上世纪提前了很多,从过去的女孩13周岁、男孩14周岁到现在的女孩10———11周岁、男孩12———13周岁,按国家九年义务教育的规定,小学的入学年龄必须要满足7周岁以上,这样在加上6年小学的教育,绝大部分学生都已进入青春期,随着青春期的提前到来,不仅身体的整体结构提早发育,性器官也在同步的发育,女孩开始出现月经而男孩也开始出现遗精的生理现象,对此,学生很有必要了解这方面的知识,为将来的身体健康打下良好的基础。
I. Necessity 1. The physical needs of students With the continuous improvement of the standard of living in our country, the time for adolescents to enter adolescence has advanced much earlier than that of the previous century. From the past, the girl was 13 years old, the boy was 14 years old and the girl now is 10— 11 years old, boys 12-13 years old, according to the national nine-year compulsory education requirements, primary school entrance age must meet 7 years of age or more, so in addition to six years of primary school education, the vast majority of students have entered adolescence, With the advent of puberty, not only the overall structure of the body develops early, but also the sexual organs develop simultaneously. Girls begin to experience menstruation and boys begin to appear physiological phenomena of nocturnal emission. In this regard, it is necessary for students to understand this knowledge. Future physical health lays a good foundation.
