请结合实际分析以下案例：
教师在上《植物的叶》一课教学时，除了通过实验让学生知道绿叶在太阳光的照射下有制造养料的作用外，主要讲清了下面的知识点：(1)光合作用需要绿叶、阳光、水、二氧化碳，缺一不可；(2)光合作用要吸收二氧化碳和水，制造有机养料，呼出氧气；(3)有机养料和氧气是人和动物所需要的；(4)人和动物在新陈代谢时呼出二氧化碳，为植物的光合作用提供了原料；(5)植物和动物的生长都离不开太阳等。学生从这些知识中认识到植物与动物之间的，动物、植物与空气、水、太阳之间的关系是非常密切的，从而认识到自然界是相互联系、相互制约的。
试说明以上这个案例体现了哪一条教学原则，它对于教师在教学过程中贯彻这一原则有哪些具体的要求

Children are a relatively modem invention. Until a few hundred years ago they look like adult, wearing grown-up clothes and grown-up expressions, performing grown-up tasks. Children did not exist because the family as we know it had not evolved.
Children today not only exist; they have taken over in no place more than in America, and at no time more than now. It is always Kids Country here. Our civilization is child-centered, child-obsessed. A kid’s body is our physical ideal. In Kids Country we do not permit middle-aged. Thirty is promoted over 50, but 30 knows that soon his time to be overtaken will come.
We are the first society in which parents expect to learn from their children. Such a topsy-turvy situation has come to abort at least in part because, unlike the rest of the world, ours is an immigrant society, and for immigrants the only hope is in the kids. In the Old Country, that is, Europe, hope was in the father, and how much wealth he could accumulate and pass along to his children. In the growth pattern of America and its ever- expanding frontier, the young man was ever advised to GO WEST; the father was ever inheriting from his son. Kids Country may be the inevitable result.
Kids Country is not at all bad. America is the greatest country in the world to grow up in because it is Kids Country. We not only wear kids clothes and eat kids food; we dream kids dreams and make them come tree. It was, after all, a boys’ game to go to the moon.
If in the old days children did not exist, it seems equally true today that adults, as a class, have begun to disappear, condemning all of us to remain boys and girls forever, jogging and doing push-ups against eternity.

A．young people are reluctant to go
B．people may possibly get wealthy
