Pesticides (杀虫剂)
Why do pesticides(杀虫剂)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 gardens and woodlands silent and birdless. 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(暴露)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 are very sad and should not occur. For the population 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(积累的) over long periods of time, and that the danger to the individual may depend on the sum of the exposures received throughout his lifetime. For these very reasons the danger is easily ignored. It is human nature to shake off(摆脱) what may seem to us a threat of future disaster. "Men are naturally most impressed by diseases which have obvious signs", says a wise physician, Dr. Rene Dubos, "yet some of their worst enemies slowly approach them unnoticed. "
It can be concluded from Dr Dubos’ remarks that______.
选项
A、people find invisible diseases difficult to deal with
B、attacks by hidden enemies tend to be fatal
C、diseases with obvious signs are easy to cure
D、people tend to overlook hidden dangers caused by pesticides
答案
D
解析
本题考查考生的逻辑分析能力。考的是从瑞尼·杜博博士的话中可以推出的结论。瑞尼·杜博博士说,“人们对那些有明显症状的疾病印象最深,然而有些最可怕的敌人却在不知不觉中慢慢地来到了身边。”由此可见,杀虫剂等化学药品的剧毒作用是长期积累的结果,正因为如此,人们往往忽视它的慢性影响。所以,正确答案是D。
