What is a good education? Is it one that covers as much as possible of human history and a
chievements, past and present? Or ode that gives graduates the ability to find employment promptly when they leave school? Is it a broad education or a specialized one? Should it provide students with a vast collection of facts, or merely train them to think? Should a future engineer gain only the knowledge that will enable him to do his job properly, or would a richer background improve his professional ability as well as his personal life? The debate goes on and on, with good arguments on both sides.

In the eighteenth and the nineteenth centuries. the question was not even worth asking. A good education was, of course, a broad one based on the humanities. An educated man knew “something about everything”. He was familiar with the great deeds and the great ideas of the past. He had read extensively;he was able to use his own language correctly and often elegantly. He could join in any conversation about plants, planets, painters, or politics. He was at ease in the world, and he knew that his education would open to him any career that he might want to try. Even if he was mostly interested in literature, he had some knowledge of the sciences and the techniques of his time。

From childhood to old age, we all use language as a means of broadening our knowledge of o
urselves and the world about us. When humans first【61】, they were like newborn children unable to use this【62】tool. Yet once language developed, the possibilities for human kinds future【63】and cultural growth increased.

Many linguists believe that evolution is【64】for our ability to produce and use language. They【65】that our highly evolve brain provides us【66】an innate language ability not found in lower【67】. Proponents of this innateness theory say that our【68】for language is inborn, but that language itself develops gradually,【69】a function of the growth of brain during childhood. Therefore there are critical【70】times for language development.

Current【71】of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable.【72】, more and more schools are discovering that foreign languages are best taught in【73】grades. Young children often can learn several languages by being【74】to them, while adults have a much harder rime learning another language once the【75】of their first language have become firmly fixed.

【76】some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been【77】from other human beings don't possess language. This demonstrates that【78】with other human beings is necessary for proper language development. Some linguists that this is even more basic to human language【79】than any innate capabilities. These theorists view language as imitative, learned behavior.【80】, children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

A.generated

B.evolved

C.born

Once they are more than a month old, babies seem to learn readily. Moreover, solving a pro
blem or discovering the relationship between their own actions and an event in the external world seems to have its own rewards for infants.

The pleasure involved in such an experience seemed obvious in one study of two-to-four- month-old infants who were given a chance to control a yellow-and-green mobile. One of these mobiles was suspended above each infant, who play in a crib (小床) with a ribbon attached to one ankle. The other end of the ribbon was attached to the hook from which the mobile was suspended. As the infants moved about, waving their arms and kicking their legs, they learned to connect the motion of one leg with the bobbing(跳动) of the mobile. As they smiled and gurgled(咯咯的笑) at the moving mobile, the infants began to kick the leg attached to the mobile forcefully and precisely and only that leg. Apparently, they enjoyed controlling the mobile, for they would continue for as long as 45 minutes.

Nor is this pleasure in mastery limited to infants. In an experiment with fifth and sixth graders, the children were asked to solve some word puzzles that varied in difficulty. The youngsters smiled more, and reported far more pleasure, when they solved a difficult puzzle than any easy one. The implication is that human beings of any age-from infancy to old age- derive pleasure from intellectual mastery.

In the experiment, the infants ______.

A.kicked their legs randomly all the time

B.kicked the leg controlling the mobile most of the time

C.attached the colorful ribbons to their own legs

D.felt very tired and lost their interest soon
