关于“种间和种内关系”问题,在学习达尔文主义基础当中,几乎已成为大家共同的争论问题,但是在课本上对这问题的说明,联系到林木之间的具体例子说得很少,同时也比较简单,据我所体会:一般中学生对于这方面的了解还很模糊,很少能理解到林木之间的关系是经过“自然选择”“系统发育”的过程而形成一种适应性的结果.现在为了在这方面能帮助同学们进一步了解“种间和种内关系”问题,我愿结合课程内容加以补充说明,藉供教材的参考资料,并希老师同学们予以指正. The issue of “interspecific and intraspecific relations” has almost become a common issue of debate among all learners on the basis of learning Darwinism. However, there are few specific examples linking textbooks to this issue and linking them to trees and trees. At the same time, it is also relatively simple. As far as I understand it, most middle school students are still very vague about this. They seldom understand that the relationship between trees is a kind of adaptability through the process of “natural selection” and “systematic development” As a result, I would like to help students learn more about “interspecific and intraspecific relations” in this respect. I would like to supplement the contents of the course with references to teaching materials and teachers and students.
