随生活水平的逐年提高,越来越多的人成了“城里人”,青少年也离乡土越来越远,自然课中的植物知识对生活在钢筋水泥中的学生,也变得更加陌生。为了让学生在上有关植物的课时能有些感性认识,自然老师不妨与市场上越来越丰富的蔬菜瓜果挂钩。 With the improvement of living standards, more and more people become “urban people” and young people are getting farther and farther away from hometown. The knowledge of plants in natural classes becomes more unfamiliar to students living in reinforced concrete . In order to allow students to have some perceptual knowledge of the classes of plants, natural teachers may wish to link with the increasingly rich fruits and vegetables on the market.
