In the stomach contents of specimens of Coelophysis (a small, long-necked dinosaur) are bones from juvenile animals of the same species. At one time, these were thought to represent embryonic animals, suggesting that this small dinosaur gave birth to live young rather than laying eggs. Further research indicated that the juvenile dinosaurs were too large and too well-developed to be prehatched young. In addition, the juveniles inside the body cavity were of different sizes. All the evidence points to the conclusion that these are the remains of prey items and that, as an adult, Coelophysis was at least in part a cannibal.
According to paragraph 5, all of the following support the claim that the adult Coelophysis sometimes ate young Coelophysis EXCEPT ________.
选项
A、Juveniles found in the body cavities of adults were too advanced in their development to be embryos.
B、Juveniles of different sizes were found in the body cavity of the same adult.
C、Juveniles found in the body cavities of adults were too large to be embryos.
D、Juveniles found in the body cavities of adults were in unhatched eggs.
答案
D
解析
题目问哪项不是成体腔骨龙(Coelophysis)有时会吃幼体腔骨龙的证据。首先看选项,找出选项的关键信息。由于四项的主语都是Juveniles,因此,选项最主要抓的是这些幼龙有所区别的特征。A项的关键信息为too advanced…to be embryos“过于发达,不可能还是胚胎状态”;B项的关键信息为different sizes were found m the same adult“在同一成体腔骨龙体内发现了不同体型的幼龙”;C项的关键信息为too large to be embryos“体型过大,不可能仍为胚胎状态”;D项的关键信息为in unhatched eggs “仍未被孵化出来”。了解到选项的关键信息后,带着这些信息来读这一段。第1、2句给出了背景信息:人们在成体腔骨龙的体内发现了幼体腔骨龙的骨头,因此,腔骨龙一度被认为是通过胎生而不是卵生来繁衍的,然后第3、4句提出证据,证明为什么说成体腔骨龙有时会吃幼体腔骨龙,而第5句得出结论。第3句中的too large and too well-developed分别对应C项和A项;第4句中的were 0f different,sizes对应B项。因此,A、B、C三项均符合原文说法,D项的信息在文中没有被提及,答案为D项。
