12.Dinosaurs ruled the planet for millions of years,and they are generally believed to have gone extinct.But the reality is that modern versions of dinosaurs are all around us.Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.
According to Mark Norell,the director of the exhibit and an expert at the museum,it is based on new scientific evidence collected over the last two decades."I think this is really going to shake up the way people think of dinosaurs"Norell told reporters."One could argue that we still live in the age of dinosaurs."
The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds.It examines several properties that are shared between the two species,including feathers,complex brains,the shapes.And sizes of eggs,and the ability to fly.Birds today make nests,lay eggs and tend to babies.Fossil research shows that some dinosaurs also made nests and laid eggs.Also,birds have hollow(中空的)bones,which don't weigh much and allow birds to take more air into their lungs.These adaptations help with flight.Some dinosaurs had these properties as well.In addition,the exhibit shows that there are many similarities between the legs,claws; and feet of dinosaurs and birds.
Norell noted that the research behind this exhibit is the result of advanced scientific,techniques; and new technologies.For example researchers used a scanning (扫描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs.It combines with many X-rays to produce a 3D image."Modern technology tells us more than we thought we could ever know about the connections between dinosaurs and birds,"Norell said.

分析 科学家们一直在探索鸟类和恐龙之间的相似之处,新的研究表明恐龙和鸟类之间存在着很多的相似之处.
解答 32.D 主旨大意题.根据第一段最后一句Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.科学家们一直在探索鸟类和恐龙之间的相似之处;而新的研究表明,这两种动物是直接联系在一起的.可知本文主要讲恐龙与鸟类之间的联系,所以答案选D.
33.B 猜测词义题.根据后边的定语从句对这个词的解释that are shared between the two species,including feathers,complex brains,the shapes这两个物种共有的,包括羽毛,复杂的大脑,形状.这些都是动物的一些特征,character是名词"特征",所以答案选B.
34.B 细节理解题.根据These adaptations help with flight.Some dinosaurs had these properties as well.In addition,the exhibit shows that there are many similarities between the legs,claws; and feet of dinosaurs and birds.可见恐龙与鸟类不仅在腿、爪子和脚之间有许多相似之处,恐龙也有飞行的特征.birds have hollow(中空的)bones,鸟类的骨头是中空的,恐龙的骨头也有这种特征.所以答案选B.
35.C 细节理解题.根据前一句Norell noted that the research behind this exhibit is the result of advanced scientific,techniques; and new technologies诺雷尔指出,这背后表现出的研究是先进的科学、技术和新技术的结果;所以后文提到CT只是为了证明这项研究运用了先进的科技,所以答案选C.
