The questions of what children learn, and how they should learn it, is continually being debated and reheated. Nobody dares any longer to defend the old system, the parrot – fashion (way of learning by repeating what others say) of learning lessons, the grammar with a whip system，which was good enough for our grandparents．The theories of modern psychology have stepped into argue that we must understand the needs of children．Children are not just small adults；they are children who must be respected as such．

Well，you may say，this is as it should be，and a good idea．But think further．What happens?

‘Education’ becomes the responsibility not of teachers, but of psychologists．What happens then? Teachers worry too much about the psychological implications of their lessons，and forget about the subjects themselves．If a child dislikes a lesson，the teacher feels that it is his fault，not the child’s. So teachers worry whether history is ‘relevant’ to modem young children．And do they dare to recount stories about violent battles? Or will this make the children themselves violent? Can they tell their classes about children of different races，or will this encourage racial hatred? Why teach children to write grammatical sentences? Verbal expression is better．Sums? Arithmetic? No：real—life mathematical situations are more understandable．

You see．you can go too far．Influenced by educational theorists，who have nothing better to do than write books about their ideas，teachers leave their teacher—training colleges filled with grand，psychological ideas about children and their needs. They make complicated preparations and try out their ‘modern methods’ on the long – suffering children. Since one ‘modern method’ rapidly replaces another, the poor kids will have well been fed up by the time they leave school. frequently the modern methods are so complicated that they fail to be understood by the teachers, let alone the children; even more often, the relaxed discipline so necessary for the ‘informal’ feeling the class must have, prevents all but a handful of children from learning anything.

屠能在《孤立国》中提出的农业区位论认为，农业应以城市为中心，做如下分布（）

A、第1圈：自由农作圈，重要生产向城市供应的体积大、重量大、易腐烂、不适宜长途运输蔬菜、水果、牛奶等，实行高度集约经营。

第2圈：谷草农作圈：该圈面积大，生产谷物和畜产品。

第3圈：林业圈，生产木材，供城市做饭、取暖、建筑和家具。

第4圈：轮作农业圈：生产谷物和豆类，轮作以解决肥料不足问题。

第5圈：三圃农作圈：谷物—牧草—休闲三圃制，低投入，供应城市经过加工的畜产品和少量谷物。

第6圈：放牧草场圈：纯牧区，粗放经营，主要畜产品自给，少部分运往城市。
