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.

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.

If you want to learn anything at school, you need to listen to your teachers. Unfortunately, millions of kids can’t hear what their teachers are saying. And it’s not because these students are goofing off. Often, it’s the room’s fault. Building architecture and building design can create echo(回声)-filled classrooms that make hearing difficult.
Children with hearing impairments（损伤）suffer most from noisy classrooms. They sometimes can’t hear questions that other students ask in class. Compared with kids with healthy hearing, they have a harder time picking up new vocabulary words by hearing them in talking.
Even kids with normal hearing have a harder time in the classroom when there’s too much noise. Younger children in particular have trouble separating important sounds – like a teacher’s voice – from background noise. Kids with learning disabilities and speech impediments（障碍）and kids for whom English is a second language also have a harder time learning in noisy situations.
In recent years, scientists who study sound have been asking schools to reduce background noise, which may include loud air-conditioners and pipes. They’re also targeting outdoor noises, such as highway traffic. Noise reduction is a big deal. Why? Because quieter classrooms might make you smarter by letting you hear your lessons better.
“It’s so obvious that we should have quiet rooms that allow for access to the lesson,” says Dan Ostergren, a hearing scientist. “Sometimes it surprises me that we spend so much time discussing this topic. I just want to go. Why is this hard for anyone to grasp?”
