今天再来温习一下做推理题的小方法哦。
★小方法★
1. 通读全文，领悟大意，理解文章结构层次及细节。
2. 选用排除法排除不符合原文细节的选项，剩下的就是要选择的最佳答案。
★小小练习★
The body that impacted Earth at the end of the Cretaceous period was a meteorite with a mass of more than a trillion tons and a diameter of at least 10 kilometers. Scientists first identified this impact in 1980 from the worldwide layer of sediment deposited from the dust cloud that enveloped the planet after the impact. This sediment layer is enriched in the rare metal iridium and other elements that are relatively abundant in a meteorite but very rare in the crust of Earth. Even diluted by the terrestrial material excavated from the crater, this component of meteorites is easily identified. By 1990 geologists had located the impact site itself in the Yucat region of Mexico. The crater, now deeply buried in sediment, was originally about 200 kilometers in diameter.
Which of the following can be inferred from paragraph 3 about the location of the meteorite impact in Mexico?
A. The location of the impact site in Mexico was kept secret by geologists from 1980 to 1990.
B. It was a well-known fact that the impact had occurred in the Yucat region.
C. Geologists knew that there had been an impact before they knew where it had occurred.
D. The Yucat region was chosen by geologists as the most probable impact site because of its climate.
答案：C
解析：该题问关于墨西哥的陨石撞击地点能推理出什么。定位原文到倒数第二句，基础较好的同学可能会注意到 “1990年之前地质学家找到了撞击地点本身在墨西哥的Yucat地区。”“本身”这个强调词给人一个问题：地质学家之前找到的是什么。带着这个疑问，基础好的同学会迅速找到1980年“科学家先根据全球范围普遍存在的一个地层确定了有这么一次撞击”，进而选出C选项。但是部分基础较薄弱的同学在读到定位区间的时候可能便没那么敏感，他们可能会选ABD中的任何一个而不会选择C。事实上，对于基础薄弱的同学来说，最准确的办法便是选项验证法。A说科学家保守秘密，文中没有任何暗示，没有依据则不选；B说撞击发生在此地区众所周知。没有事实依据，但也不能确定错误，不选；C说地质学家先知道撞击事件后发现撞击地点，去文章中一对，的确如此，入选。D说地质学家选取了该地区是因为它的气候，而文章中跟气候沾边的信息—哪怕温度啥的—都没有提，无事实依据，不选。
译文反白可见
译文：身体,影响了地球的白垩纪时期是一个陨星质量超过一万亿吨,直径至少10公里。科学家首次发现这种影响在1980年从全球层沉淀物形成的尘云,包围后的地球的影响。这种沉积物层是丰富的稀有金属铱和其他元素相对丰富的陨石中但非常罕见的地壳的地球。即使稀释的地面材料出土的火山口,这个组件的陨石很容易识别。到1990年,地质学家已经找到了影响站点本身在墨西哥Yucat地区。这个陨石坑,现在深深埋在沉积物,最初是直径约200公里。
