Watch a baby between six and nine months old,and you will observe the basic idea of geometry（几何学）being learned.Once the baby has mastered the idea that space is three dimensional（空间的）,it reaches out and begins grasping various things,that the ideas of sets and numbers are formed.So far,so good.But now an ominous development takes place.The nerver fibers in the brain separate themselves in such a way that the baby begins to hear sounds very exactly.Soon it picks up language.And it is then brought into direct communication with grown-ups.From this point on,it is usually downhill all the way for mathematics,because the child now becomes exposed to all the rubbish words and beliefs of the born.Nature,having done very well by the child to this point,having permitted it the luxury（奢侈）of thinking for itself for eighteen months,now gives it up to the unreasonable conventions（惯例）and beliefs of society.But at least the child knows something of geometry and peaceful days,no matter what vicissitudes（兴衰变迁）it may suffer later on.The main reservoir of mathematical ability in any society is thus possessed by children who are about two years old,children who have just learned to speak freely.
【小题1】What does the passage mainly discuss?A．The impact（影响）of language on mathematics.B．Children’s ability to learn languages.C．How basic ideas of physics are learned?D．Maths-learning strategies（策略）for babies.【小题2】According to the passage,which of the following activities would teach a baby about geometry?A．Picking up a wooden block.B．Recognizing the number 2.C．Saying a rubbish word.D．Looking at a distant word.【小题3】Which of the following conclusions is true according to the writer?A．The language ideas used in early education interrupt mathematical reasoning.B．It is hopeless to try to teach children mathematics after the age of two.C．Language teaching should join some mathematical formulas（公式）.D．Preschool education should emphasize society’s beliefs and conventions.A

(答案→)A 解析：【小题1】纵观全文可知。【小题2】见第一段第一、二句。【小题3】见文章最后一句。
