英语四级考试阅读模拟题(一)
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, 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,
farmworkers, and others exposed to sufficient quantities of
pesticides is 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 the danger to 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.

英语四级考试阅读模拟题答案
1.[B] 题干的句子是文章第1段第3句,这是一个带有插入语的简洁句,contrary在此表示跟part of nature相反,因此答案为B。 2.[D] 第2段最终一句提到,我们必需更加关注汲取少量杀虫剂的潜在后果,它们正在不知不觉地污染我们的世界。因此,对杀虫剂对环境的影响关注且担忧,D符合题意。
3.[A] 第2段第2句提到,杀虫剂使人突然发病或者死亡是很令人难受的亊,对于人口整体来说,人类对杀虫剂长期累计的潜在后果的熟悉不足,才是最严峻的问题,故选A。
4.[C] 依据第3段倒数第2句说的"对将来的灾难无动于衷是人的本性'以及最终一句说的大多数人只对有明显迹象的疾病予以关注'可知C正是人们忽视化学药物的潜在危害的缘由,故选C。
5.[D] Dubos博士话中"最可怕的敌人'指的是"杀虫剂引起的潜在危急',博士话中的slowly approach them unnoticed直接表明D正确。

Just seven years ago, the Jarvik-7 artificial heart was being
cheered as the model of humancreativeness. The sight of Barney
Clark-alive and conscious after trading his diseased heart fora
metal-and-plastic pump-convinced the press, the public and many
doctors that the futurehad arrived. It hadnt. After monitoring
production of the Jarvik-7, and reviewing its effects onthe 150 or
so patients (most of whom got the device as a temporary measure)
the U.S. Foodand Drug Administration concluded that the machine was
doing more to endanger lives thanto save them. Last week the agency
cancelled its earlier approval, effectively banning (禁止)the device.
The recall may hurt Symbion Inc., maker of the Jarvik-7, but
it wont end the request for anartificial heart. One problem with
the banned mode is that the tubes connecting it to anexternal power
source createda passage for infection. Inventors are now working
on newdevices that would be fully placed, along with atiny power
pack, in the patients chest. The firstsample products arent expected
for another 10 or 20 years. But some people are alreadyworrying that
theyll workand that Americas overextended healthcare programs will
