不得不想说了,当我再读读的时候我也觉得还是c好(在做这篇的时候也选的c,不过看到人家说是争议我也就没管了...为了练习所谓的逻辑分析能力提高对逻辑题的感觉..) 首先:anthropologist Shepard Krech points out that large animal species vanished even in areas where there is no evidence to demonstrate that Paleoindians hunted them. Nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption. SK这个人指出了没有证据去证明是P去hunt这些大型动物的,另外一方面也说不仅仅是大型动物,连那些一般人不会去consume的小动物也灭绝=======引申含义就是不同意人是动物灭绝的主要因素; 其次,Krech also contradicts Martin’s exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene SK这个人继续说了,M这个人没有考虑到气候因素,因为大范围的气候变化正好发生在那个特定的时候====引申就是widerspread climatic change是因素 我们来看b:New discoveries indicating that Paleoindians made use of the small animals, plants, and insects that became extinct 还是同意定语从句的错误,用了已经灭绝的小型生物的东西,不能削弱SK的观点; c:Additional evidence indicating that widespread climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras 过去都已经发生过了,没有造成影响,而非说后来的一次造成影响.不是强词夺理么? 另外楼主所举的那个例子我认为欠妥:原文的推理是卫生条件改善==>今年比去年得肠炎的少;A选项是说5年前建立了新的自来水厂.we should compare this year with last year, not this year with five years ago! |
