题目详解:在整篇文章中提供的事实和描述的方式，可以看出作者仅仅客观地叙述了整个事件，并没有附加任何评论观点，由此，可以判断与选项中的\含义相关。 Education is one of the key words of our time. A man without an education, many of us believe, is an unfortunate victim of unfortunate circumstances deprived of one of the greatest twenty-first century opportunities. Convinced of the importance of education, modern states \in institutions of learning to get back \in the form of a large group of enlightened young men and women who are potential leaders. Education, with its cycles of instruction so carefully worked out, punctuated by textbooks ---those purchasable wells of wisdom ---what would civilization be like without its benefits?

So much is certain: that we would have doctors and preachers, lawyers and defendants, marriages and births; but our spiritual outlook would be different. We would lay less stress on \and figures\and more on a good memory, on applied psychology, and on the capacity of a man to get along with his fellow citizens. If our educational system were fashioned after its bookless past we would have the most democratic form of \imaginable. Among the people whom we like to call savages all knowledge inherited by tradition is shared by all; it is taught to every member of the tribe so that in this respect everybody is equally equipped for life. It is the ideal condition of the \start\which only our most progressive forms of modem education try to regain. In primitive cultures the obligation to seek and to receive the traditional instruction is binding to all. There are no \－ if the term can be applied to peoples without a script---while our own compulsory school attendance became law in Germany in 1642, in France in 1806, and in England in 1967, and is still non- existent in a number of \nations. This shows how long it was before we deemed it necessary to make sure that all our children could share in the knowledge accumulated by the \few\during the past centuries.

Education in the wilderness is not a matter of monetary means. All are entitled to an equal start. There is none of the hurry which, in our society, often hampers the full development of a growing personality. There, a child grows up under the ever-present attention of his parents; therefore the jungles and the savages know of no \delinquency\No necessity of making a living away from home results in neglect of children, and no father is confronted with his inability to \an education for his child.

Where do pesticides fit into the picture of environmental disease? We have seen that they now pollute soil, water and food, that they have the power to make our streams fishless and our garden and woodlands silent and bird less. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world?

We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the pollution as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.

Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to the individual may depend on the sum of exposures received throughout his lifetime. For these very reasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. \are naturally most impressed by diseases which have obvious signs,\says a wise physician. Dr.ReneDubos, \some of their worst enemies slowly approach them unnoticed.\ ________________________________________
