LZ8.23考的，碰到的第三篇差不多就是就是下面这篇，两屏多，LZ只看了个大概，是我做的最不好的一篇，五个问题细节观点主旨高亮“the last meal”都考到了，记忆深刻，但由于看的模糊没能及时奉上机经，今天网上一搜再一看。。。竟然就是它
题目（暗示主旨吧）：The last supper of the hominids establishes the times they lived at the sites
正文：
In the French cave of Arago, an international team of scientists has analyzed the dental wear of the fossils of herbivorous animals hunted by Homo heidelbergensis. It is the first time that an analytical method has allowed the establishment of the length of human occupations at archaeological sites. The key is the last food that these hominids consumed.（这一段文中不是这么说的，或许没说，大家当背景资料了解）
For many years, the mobility of the groups of hominids and how long they spent in caves or outdoors has been a subject of discussion among scientists. Now, an international team headed by researchers from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) in Tarragona has based its studies on the dental fossils of animals hunted by hominidsin order to determinethe vegetation in the environment and the way of life of Homo heidelbergensis（一种古人类吧）.
注意我标记的字，如果我没记错的话，这差不多就是第一段。。。
以上内容重点在于：展示了这项研究的手段（黑体字）
Florent Rivals is the main author and a researcher from the Catalan Institute for Research and Advanced Studies (ICREA), attached to the IPHES in Tarragona. "For the first time, a method has been put forward which allows us to establish the relative length of the human occupations at archaeological sites as, up until now, it was difficult to ascertain the difference between, for example, a single long-term occupation and a succession of shorter seasonal occupations in the same place", he explained to SINC.
（红背景的字文中绝对出现了！其余不确定）
以上段落重点在于：辨别 在同一地点的a single long-term occupation（长期居住） 和 shorter seasonal occupation（季节性居住）是这个研究的目的
In the study, recently published in the Journal of Human Evolution, the researchers analyze the dental wear of the ungulates (herbivorous mammals) caused by microscopic particles of opaline silica in plants. These marks appear when eating takes place and erase the previous ones. This is why they are so useful.
黄背景的文中也出现了，展示了具体研究的方法和研究内容
Thanks to the "last supper phenomenon", the scientists have been able to analyze the last food consumed by animals such as the Eurasian wild horse (Equus ferus), the mouflon (Ovis ammon antiqua) and the reindeer (Rangifer tarandus). "This method allows us to confirm the seasonal nature of the occupation", Rivals added. According to the team, the microwear of the teeth is sensitive to seasonal changes in the diet.
LZ觉得上面这一段差不多就是原文。。。the last food（好像是meal来着）高亮了
The application has allowed the researchers to estimate the length of the occupation of the site from the Lower Paleolithic Age in the cave of Arago (France) by the number of marks on the fossils and, therefore, the variation in the diet of several species of herbivores, as "each season presented food resources which were limited and different in the environment", the paleontologist clarified
嗯，上面这一段差不多是文章的最后一段了，Lower Paleolithic Age记忆深刻。。。
后面这些内容不去定出现类没有，也贴上来大家看看
High and low periods of occupation
After confirming the hypothesis in present-day animals whose age and date of death was known to the scientists, the researchers demonstrated that, if a group of animals is seen during a specific season (a short-term occupation), the signs of dental wear undergo little variation. But if the occupation lasts several seasons, the dental marks are more diverse.
"If the animals are hunted during long periods of occupation, more variable dental wear would be expected", Rivals declared. In the case of the French cave of Arago, the study of the dental wear confirms that it was occupied in different ways. "With this method, we were able to prove that at the site, which belonged to Homo heidelbergensis, there is evidence of differing mobility, as there were highly mobile groups and others with little mobility", the scientist confirmed.
The Spanish and German researchers have combined this application with multidisciplinary studies of archaeological sites in order to apply it to other settlements of the Mid-Paleolithic Age such as Payre (France), Taubach (Germany) and Abric Romani (Spain).
就是这些，基本上就是考试原文了，可能多一些，希望对大家有用。下面附上链接，网页上的字太小了就是。。。
