新教材是按照突出人与生物圈的密切关系的思路来设计的。由此可以看出“了解生物圈”这一章节对于整套教材之重要性。作为教师在教学中则应该认真体会这一重要性,在讲授时应该始终围绕生物和环境的整体性这条主线,做到形散而神不散。 The new textbook is designed to highlight the close relationship between people and the biosphere. From this we can see the importance of “Understanding the Biosphere” section for the entire teaching material. As a teacher, you should carefully understand this importance in teaching. When teaching, you should always focus on the main line of the integrity of biology and environment so that it can be shaped and dispersed.
