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 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 to these chemicals, ff 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, anti 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 over long periods of time, and that file 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 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 sighs are easy to cure
D、people tend to overlook hidden dangers caused by pesticide
答案
B
解析
从文章的最后一句话中的worst,我们可以断定潜伏的敌人才是最危险的。所以选B。
