问题     Watch a baby between six and nine months old, and you will observe the basic concepts of geometry being learned. Once the baby has mastered the idea that space is three-dimensional, it reaches out and begins grasping various kinds of objects. It is then, from perhaps nine to fifteen months, that the concepts of sets and numbers are formed. So far, so good. But now an ominous development takes place. The nerve fibers in the brain insulate themselves in such a way that the baby begins to hear sounds very precisely. Soon it picks up language, and it is then brought into direct communication with adults. From this point on, it is usually downhill all the way for mathematics, because the child now becomes exposed to all the nonsense words and beliefs of the community into which it has been so unfortunate as to have been born. Nature, having done very well by the child to this point, having permitted it the luxury of thinking for itself for eighteen months, now abandons it to the arbitrary conventions and beliefs of society. But at least the child knows something of geometry and numbers, and it will always retain some memory of the early halcyon days, no matter what vicissitudes it may suffer later on. The main reservoir of mathematical talent in any society is thus possessed by children who are about two years old, children who have just learned to speak fluently.  
What does the passage mainly discuss?
选项 A、How basic concepts of physics are learned.
B、Math-learning strategies for babies.
C、How basic concepts of physics are learned.
D、Math-learning strategies for babies.
答案A
解析 本文主要讨论语言对数学的影响。作者说，孩子在6个月到9个月的时候开始了解几何概念，从9个月到15个月的时候形成集合和数字的概念。但就在这个时候，大脑中的神经纤维相互分隔开来，婴儿开始准确地听见声音。孩子不久就学习语言，接着同成人直接交流，从这个时候起，孩子的数学开始走下坡路。
