我自己选的A，取非，好像也加强argument。版本1无解释的答案是A, 版本2有解释的答案D如下：

38. Amphibian populations are declining in numbers worldwide. Not coincidentally, the earth’s ozone layer has been continuously depleted throughout the last 50 years. Atmospheric ozone blocks UV-B, a type of ultraviolet radiation that is continuously produced by the sun, and which can damage genes. Because amphibians lack hair, hide, or feathers to shield them, they are particularly vulnerable to UV-B radiation. In addition, their gelatinous eggs lack the protection of leathery or hard shells. Thus, the primary cause of the declining amphibian population is the depletion of the ozone layer.

Each of the following, if true, would strengthen the argument EXCEPT:

A.   Of the various types of radiation blocked by atmospheric ozone, UV-B is the only type that can damage genes.
B.   Amphibian populations are declining far more rapidly than are the populations of non-amphibian species whose tissues and eggs have more natural protection from UV-B.
C.   Atmospheric ozone has been significantly depleted above all the areas of the world in which amphibian populations are declining.
D.   The natural habitat of amphibians has not become smaller over the past century.
E.   Amphibian populations have declined continuously for the last 50 years.

答案：D
思路：原文论述臭氧层的破坏造成UV-B辐射过量是导致两栖动物数量减少的主要原因。
A：支持说明为什么是UV-B而不是其他原因。
B：支持说明为什么UV-B会降低两栖动物的数量。
C：提供空间论据说明臭氧层受损和两栖动物数量减少的相关性。
D：中性评价。不Weaken也不Strengthen.
E：提供时间论据说明臭氧层受损和两栖动物数量减少的相关性。

A is right.

I think D is the right answer, because I can not find a reason to support the argument from D.

我选的也是A 感觉D又提到了另一个影响因素，没什么直接作用

sdcar2010 · 发表于 2012-3-2 10:58:59

The natural habitat of amphibians has not become smaller over the past century.

D) removed another possible reason to explain the phenoma of decreasing population. Thus, it is a strengthener since it is more likely what the author says is correct.

谢谢各位大牛，先回复再看

所以答案是A，网上通用的答案D为错？

Beilo · 发表于 2012-4-12 15:34:30

答案应该是A吧？！D实际上是排除他因，就是说数量减少不是由栖息地减少造成的，从而加强了论点吧……

同意！

D典型的加强型的 ... 排除他因就是对结论的支持
A不相关，对结论产生不了任何影响
