题干:作者对 amphibian extinctions
考作者态度,选项带入,排除法
A They have resulted primarily from human activities causing environmental degradation.
原文相反:n endangered population is always rare, almost always small, and, by definition, under constant threat of extinction even without a proximate cause in human activities.
B They could probably have been prevented if timely action had been taken to protect the habitats of amphibian species.
原文无涉及protect the habitats of amphibian species
C They should not come as a surprise, because amphibian populations generally have been declining for a number of years. 无涉及because之后内容
D They have probably been caused by a combination of chance events.
提到chance events,但是无涉及a combination of chance events
E They do not clearly constitute evidence of general environmental degradation.

关键词amphibian extinctions that have recently been reported,定位第一段。 第一段环境学家给出观点,第二段作者反驳观点。 A. 环境学家观点,错。 B. 为最后一段观点,但最后一段也没有提及habitats,错。 C. 为第二段观点。但第二段没有说是因为decline in population,只是说了population基数一直很小,没有体现decline,错。 D. 为第二段观点,但原文是may(有这个可能性但不一定),选项probably(大概率是,几乎肯定)夸大可能性,错。 E. 第一段环境学家给出的观点,作者第二段进行反驳。选项符合。

第一段环境学家说:人类活动→恶化→灭绝 但是作者分类讨论:辨析了Extinctions的灭绝有两种情况: 第一种是第二段提到的:本身物种就是endangered population,灭绝与人类活动无关。也就是说,不是人类活动导致,也就不是环境恶化导致的。(under constant threat of extinction even without a proximate cause in human activities) 第二种是第二段说的:不正常的population decline导致的灭绝,这种是因为环境变化导致的灭绝。(Persistent declines, especially in large populations, indicate a changed ecological context.) 结合这两种情况,作者就反驳了环境学家的观点一定是人类造成的环境恶化导致的灭亡。

选项:amphhibian extinctions do not constitute evidence of environmental degradation, 翻译:灭绝不是由环境恶化导致B=C。 文中:没有明说 两栖动物灭绝不是由环境恶化导致,但是有说:人类活动对灭绝不构成直接影响A不=C。 第一段又说:是人类活动导致的环境恶化A=B。

同义改写: It is indisputably true that there is simply not enough long-term scientific data on amphibian populations to enable researchers to identify real declines in amphibian populations.

题干文的是作者想法, 直接去第四段定位。
这就是一个同义改写“It is indisputably true that there is simply not enough long-term scientific data on amphibian populations to enable researchers to identify real declines in amphibian populations.“。

陷阱题,很多人忽视了题干里的that have recently been reported? 就直接根据extinctions去第2段找了。其实定位句在第1段。 reports of apparently drastic declines in amphibian populations and of extinctions of a number of the world’s endangered amphibian species.这里reports里的两块,包括题干里的the amphibian extinctions that have recently been reported都属于these declines,注意第2句话里的these指代词。所以要在declines in population找答案,而非在extinction里找。 这里的extinction和文章区分概念decline in population VS extinction不同,它属于decline的内容

author肯定是反驳environmentalists 观点的,所以对environmentalists 观点进行取反。 These declines, if real, may be signs of a general trend toward extinction, and many environmentalists have claimed that immediate environmental action is necessary to remedy this “amphibian crisis,” which, in their view, is an indicator of general and catastrophic environmental degradation due to human activity.

从文章整体来看,中间两端都是在介绍一些关于“物种减少”“物种灭绝”等的一些知识,真正在表明作者观点的是第一段和第四段。 如果不是很能理解上面这句话,建议全文翻译成中文再理解一下。

因为may在英文中是可能,可能由这个原因导致,也可能不是这个原因,表多种可能之一。而probably是指大概率的就是它了,别的原因没多大希望了。 这是有区别的!
