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. "
Which of the following is closest in meaning to the sentence "Man is part of nature. " (Line 3~4, Para.1)?
选项
A、Man appears indifferent to what happens in nature.
B、Man acts as if he does not belong to nature.
C、Man can avoid the effects of environmental pollution.
D、Man can escape his responsibilities for environmental protection.
答案
B
解析
本题考查考生对特定语言的理解能力。考的是找出与所给句子Man,however much he may like to pretend the contrary,is part of nature. 意思相近的句子。解题的关键是正确理解原文句子的意思。在这里,however相当于no matter how,引导条件状语从句,这句话的意思是:人类不论怎样假装,仍是大自然的一部分。选项A人对自然界中发生的事情漠不关心,选项C人可以避免环境污染的后果,和选项D人可以推卸他对环境的责任,都与原句相差甚远。只有选项B人类进行各种各样的活动,好像他们不属于自然似的,与之相接近。所以, 正确答案是B。
