What is the significance of the newly discovered fossils? [br]
Chinese scientists have discovered fossils of a feathered, four-winged dinosaur, which they say give new clues to the origins of flight. The creature lived about one hundred and twenty-five million years ago and was less than a meter long. The creature couldn’t actually fly but would have used its four wings and long feathery tail to help it glide from tree to tree as flying squirrels do today. It’s relative of the dinosaur Micro-Raptor. The discovery could change ideas about how birds evolved. Most experts thought they came from dinosaurs that lived on the ground and developed feathery limbs, which they flapped so they could run faster. But this latest find supports an alternative theory that birds evolved from animals that lived in trees. This was first suggested around 1915, but there’s been little evidence to support it until now.
选项
A、The creature in fossils lived about 125 million years ago.
B、The creature in fossils had feather and four wings.
C、The creature in fossils was less than a meter long.
D、The creature in fossils could run faster than other dinosaurs.
答案
D
解析
细节判断题。选项中的各项表述的内容都在新闻中出现过,但是只有D项的内容是来源于以前大家的推测,认为鸟类起源于生活在陆地上的恐龙,它们的四肢后来长出了羽毛,这样它们拍打起来就能跑得更快。这点并不是所发现的化石提供的,是专家的推测,不能成为化石的特征,而其他项都是有科学依据的,因此选D项。
