今天看到practice#1-essay 18,跟glhelr的观点有些出入,遂拿出来讨论下,也不知道是不是有人发过。
A recent study has provided clues to predator-prey dynamics in the late Pleistocene era. Researchers compared the number of tooth fractures in present-day carnivores with tooth fractures in carnivores that lived 36,000 to 10,000 years ago and that were preserved in the Rancho La Brea tar pits in Los Angeles. The breakage frequencies in the extinct species were strikingly higher than those in the present-day species. In considering possible explanations for this finding, the researchers dismissed demographic bias because older individuals were not overrepresented in the fossil samples. They rejected preservational bias because a total absence of breakage in two extinct species demonstrated that the fractures were not the result of abrasion within the pits. They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data. The explanation they consider most plausible is behavioral differences between extinct and present-day carnivores--in particular, more contact between the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct species. Such thorough carcass consumption implies to the researchers either that prey availability was low, at least seasonally, or that there was intense competition over kills and a high rate of carcass theft due to relatively high predator densities.
文章的七经八脉: 一个最近的研究提供了在Pleistocene时期捕猎者与被捕者的动态关系----比较了现在的动物和以前的动物的牙齿毁坏程度----从前的动物更严重----驳斥了三个偏见----提出作者自己认为最合理的解释。 这篇文章总体的难度不大,主旨比较明确,第一段介绍,第二段议论,属于比较典型的GMAT文章。 ------------------------------------------------------------------------------------------------------- 以上是原文和原来的文章框架,想要讨论的有以下: 1、文章结构。 glhelr原来是说第二段是驳斥了三个偏见,并提出了作者自己认为最合理的解释,本人认为不妥,有以下evidence. 来看这三个bias: (1)......, the researchers dismissed demographic bias because..... (2)They rejected preservational bias because... 很显然,they在这里指代的是第一个bias中的主语the researchers; (3)They ruled out local bias because...很显然,they在这里指代的和第二个bias是一样的,是第一个bias中的主语the researchers; 那么最后文章纳入考虑的是什么explanation呢? 原文:"The explanation they consider most plausible is behavioral differences between extinct and present..." 这里explanation是被"they" take into consideration的,这个they指代的,很明显也是第一个bias中的主语the researchers。 所以文章结构中,glhelr所述驳斥了三个偏见,并提出作者自己认为最合理的解释,我认为应该是列出了研究学者们排除的三个可能性,而将一个比较有可能的作为对文章中的founding的explanation。
2、该文章的类型。 glhelr原来是说:“第一段介绍,第二段讨论”,我个人认为言下之意是说这篇文章是议论文。但是通读全文,其实并没有议论文的特征。 什么是议论文?定义:议论文是对某个问题或者某件事进行分析、评论并发表自己的观点、立场、态度、看法和主张的一种问题。三要素分别是:作者的论点,支持论点的论据,以及围绕论点,提出论据而进行的论证过程。 反观这篇文章,全篇仅仅是在介绍一个研究发现,并且阐述了researchers对这个发现的原因,并没有设计任何作者自己的论点,也没有支持论点的论据,更没有一个论证的过程。所以这篇是一篇说明文。 说明文的定义也一起附上:说明文是通过解释概念来说明事物的特征、本质及其规律,一般介绍事物的特征、形状、构造,解释事物的原理、含义、特点、演变经过等。
以上看法,欢迎大家讨论~~~ |
