How to Do Fewer, Better Animal Experiments
For a nation of pet lovers, Britain conducts a surprising number of experiments on animals some 3 million a year. America appears to use fewer animals—just 1.1 million a year, according to official statistics, but that is an illusion. Unlike Britain’s government, American does not think rats and mice worth counting. Japan and China have even less comprehensive data than America, and animals used in research in those two countries are not protected to the same extent that they are in the West. Even so, academic centers supporting alternatives to animal testing have emerged in both places in recent years. In July China issued its first set of guidelines governing the use of animals in research.
In an ideal world, there would be no animal testing. It is expensive and can be of dubious scientific value, since different species often react differently to the same procedure. That is why many researchers are working on ways of reducing the number of animal experiments needed and of making those that still happen more effective. However, the transition is proved easier for some types of experiments than for others, as a group of researchers in the field discussed at the sixth World Congress on Alternatives and Animal Use in the Life Sciences, held last week in Tokyo.
The most important message from the congress was that things are going in the right direction. The number of animals used in experiments has fallen by half in the past 30 years, at least in those countries that record such things. There has also been a shift in the sort of animals used. Most of those employed today are rodents rather than dogs, cats, rabbits and monkeys. (That public opinion generally welcomes, this is, however, a good example of "cutist" prejudice for one specy over another: there is no reason to believe that rodents suffer less than other mammals.) Also, of the experiments that are still conducted, the majority are now concerned with developing and testing medicine rather than, say, checking how toxic cosmetics are. Of the animals involved each year in experiments that have to be reported to the European Commission, about 45% are used for medical and veterinary purposes and another 35% for basic biomedical research.
The cutist prejudice probably refers to the fact that____.
选项
A、pet animals are thought to suffer more in experiments
B、rodents are believed to react in the same way with humans
C、testing medicine is supposed to do more harm than testing cosmetics
D、what sort of animals to use is reckoned more crucial than whether to use them
答案
A
解析
题目问The cutist prejudice涉及什么事实。通过阅读文章可知,现在,做动物实验中,更多的使用啮齿动物,而不是猫、狗、兔子和猴子。人们存在的一个偏见是,啮齿动物在试验过程中所受痛苦会比其他动物小。第三段“That public opinion generally welcomes this is,however,a good example of“cutist”prejudice for one species over another:there is no reason to believe that rodents suffer less than other mammals.”所以,答案是A。
