哎,问题真是越来越多了,请各位nn们留住脚步,再帮我分析一道题目吧~OG12    360页中,the explanation they consider most plausible is behacioral differences between extinct and present day carnivores--in particular, more contact beteen the teeth of predators and the bones of prey due to more thorough consumption of carcasses by the extinct epecies. such thorough carcass consumption consumption implies to the researchers either that prey abailablity 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. 这两句是什么关系呢?平行? 递进?是不是都属于explanation about finding啊??  我真的是栽进去了· -- by 会员 sinya566287 (2009/11/5 11:07:33)
这篇文章先告诉我们一个考古发现:The breakagefrequencies in the extinct species were strikinglyhigher than those in the present-day species 说灭绝了的动物的牙齿骨折的概率比现代动物要高 底下一段便要对这个现象进行解释。。。巴拉巴拉说了一大堆bias的问题就是为了就是为了说明要排除这样那样的偏差。。(啰里八嗦的就是为了表现他的严谨性)接着说排除了以上这些,那最合理的解释就是行为上的差异了。。。破折号后面对这个差异进行了解释。。最后一句话如果要说跟前面一句什么关系的话应该说是递进吧,也可以理解为一种补充。。考古发现-->more thorough consumption of carcasses-->prey availability was low |
