  Topic   The following is a letter to the editor of an environmental magazine

  "The decline in the numbers of amphibians worldwide clearlyindicates the global pollution of water and air. Two studies ofamphibians in Yosemite National Park in California confirm myconclusion. In 1915 there were seven species of amphibians in the park,and there were abundant numbers of each species. However, in 1992 therewere only four species of amphibians observed in the park, and thenumbers of each species were drastically reduced. The decline inYosemite has been blamed on the introduction of trout into the park’swaters, which began in 1920 (trout are known to eat amphibian eggs).But the introduction of trout cannot be the real reason for theYosemite decline because it does not explain the worldwide decline."

  Sample Essay

  In this argument, the writer of the letter concludes that globalpollution of water and air has caused a decline in the number ofamphibians worldwide. To support his or her conclusion, the writercites the results of two studies, seventy-five years apart, thatpurportedly show that the number of amphibians in one park inCalifornia, Yosemite National Park, have drastically declined.Additionally, the writer casts aside a given reason for the decline,stating that the introduction of trout to the park (who are known toeat amphibian eggs) does not explain the worldwide decline in thenumber of amphibians. This argument defies simple logic and suffersfrom several critical fallacies.

  First of all, the argument is based on only two studies in onespecific part of the world, Yosemite National Park in California. It isimpossible to pinpoint a worldwide theory for the decline of amphibiansbased on any number of studies in only one specific location in theworld - the specific varieties of amphibians, geographical conditionsand other location specific variables prohibit such a sweepinggeneralization. One very specific location cannot be used as a modelfor all other locations, even within one particular country, let alonethe entire world. The writer provides no evidenced whatsoever thatlinks the Yosemite study with any purported effects anywhere else inthe global environment.

  Secondly, the two separate studies were done seventy-five yearsapart. There is no evidence that the two studies were conducted in asimilar manner over the same duration of time or even over the sameexact areas of Yosemite National Park, or that the exact same studymethods were used. For example, perhaps the first study lasted over anentire year and was conducted by twenty-five experts in amphibiousbiology, resulting in the finding of seven species of amphibians inabundant numbers. By contrast, perhaps the second study was conductedover a period of one week by a lone high school student as a schoolscience project. The writer offers no basis on which to compare the twostudies, leaving it open as to whether the two are truly comparable intheir breadth, scope and expertise.

  Finally, the writer notes that the decline in the amphibianpopulation has been blamed on the introduction of trout into the park’swaters in 1920, but then dismisses that argument on the purely speciousbasis that it does not explain the worldwide decline. This part of theargument blithely dismisses the very relevant fact that trout are knownto eat amphibian eggs. This attempt to "prove a negative" is the lastresort of those in search of some vain attempt to prove the truth ofthe matter that they are asserting. It is basically impossible to"prove a negative"; this is an attempt to shift the burden of proofback on to the nonbelievers of the argument. The global environmentalsituation and that of Yosemite National Park are not perfectlycorrelated, and the fact that the trout may very well be responsiblefor the decline cannot simply be dismissed without further proof.

  In summary, the writer fails to establish any causal relationshipbetween global air and water pollution and the decline of amphibiouslife worldwide. The evidence presented is extremely weak at best andnarrowly focuses on one tiny area of the globe, as well as puttingforward as proof two studies about which almost nothing is known. For astronger argument, the writer would need to directly put forth evidenceassociating air and water pollution with not only the decline atYosemite but also throughout other areas of the world.

  [题目]

  下述文字摘自一封致某环保杂志编辑的信函:

  "全球两栖动物数量的减少明显标志着全球性水与大气的污染。对加利福尼亚州约塞米蒂国家公园内两栖动物所作的两项研究可证实我的这一结论。1915年公园内有七个物种的两栖动物,每一物种都拥有丰富的种群数量。然而,1992年,在公园内所能观察到的两栖动物物种仅为四类,且每一物种的种群数量已骤然下降。约塞米蒂公园动物数量减少被归咎于始于1920年的将鲑鱼引入公园水域的做法(众所周知,鲑鱼喜食两栖动物所产的卵)。但鲑鱼的引入不可能成为约塞米蒂公园动物数量减少的真正原因,因为它无法来解释全球范围内的动物数量减少。"

  [范文正文]

  在本项论述中,信函作者的结论是,全球性水与大气污染已致使世界范围内两栖动物的数量减少。为了支持其论点,作者援引了两份时隔75年之久的研究结果,这两份结果据称可证明加利福尼亚州某一公园――即约塞米蒂国家公园――内两栖动物的数量窦酢4送猓?米髡咂部?硕?锸?考跎俚囊桓鲆阎??颍?率龅溃??儆阋?牍??据称,鲑鱼喜食两栖动物所产的卵)这一做法不足以解释世界范围内两栖动物数量上的减少。这一论点有悖于简单的逻辑,犯有一系列关键性的逻辑谬误。

  首先,该论点所依据的仅仅是世界上某一特定地点――即加利福尼亚州约塞米蒂国家公园――内的两份研究。围绕着两栖动物数量减少这一问题,如果仅以世界上一个特定的地点为样品,再多数量的研究也无法得出一种精确的、适用于全世界的理论。两栖动物的具体种类、地理状况以及其他因地点而特异的变数均不允许我们作出如此一概而论的总括。一个非常具体的地点不能用作一个代表所有其他地点的模型,即使在一个特定的国家内也不行,更不用说在整个世界范围内了。信函作者没有提供任何证据将约塞米蒂公园的研究与全球环境中任何其他一处地方的任何所宣称的效果联系起来。其次,所提及的那两项互为独立的研究时隔75年之久。没有证据可证明这两项研究是在相同的时间跨度内以相似的方式进行的,或是在约塞米蒂公园完全相同的地点进行的,或所使用的研究方法绝然相同。例如,第一项研究可能持续了整整一年之久,且是由两栖动物生物学领域的二十五位专家共同进行的。结果是发现了七大种类数目众多的两栖动物。相反,第二项研究可能是一位高中生孤身一人所做的学校的一个科学课题,仅为期一个星期。信函作者没有提供将此两项研究进行比较的基础,从而使两项研究在其广度、范围以及专业水准方面的可比性不得而知。最后,信函作者指出,两栖动物种群数量的减少,已被人归咎于1920年将鲑鱼引入公园水域这一做法,但紧接着又以该论据无法解释世界范围内动物数量减少这一似是而非的依据将该论据予以否认。信函作者论述中的这一部分漫不经心地将一个极为相关的事实弃置不顾,即众所周知,鲑鱼喜食两栖动物所产的卵。这种"prove a negative"的尝试往往是这样一类人所惯用的最后伎俩,他们竭力寻找某种徒劳的尝试,力图去证明他们所宣称的事物的真理。从根本上讲,"prove anegative"是不可能的。这样一种做法是试图将论证的负担重新转嫁给不相信该论据的人。全球的环境情形与约塞米蒂公园的情形并不绝然对应。鲑鱼极有可能造成了两栖动物数量减少这一事实在缺乏进一步证据的情况下是断不能轻易予以否认的。

  概括而言,信函作者没能在全球空气和水污染与世界范围内两栖生命数量减少之间建立起任何因果关系。该作者所拿出的证据充其量也是极为苍白无力的,狭隘地将焦点集中在世界的一片极小的区域上,作为证据而援引的两项研究几乎不能说明任何问题。欲使其论点更具力度,信函作者尚需摆出直接的证据,将水和空气污染不仅仅与约塞米蒂公园的两栖动物数量减少联系起来,而且也与世界其他地方的动物数量减少联系起来。
