What is the significance of the newly discovered fossils?
Chinese scientists have discovered fossils of a feathered, four-winged dinosaur, which they say gives 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 a relative of the dinosaur Micro Raptor. The discovery could change ideas about how birds evolved. (26) 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、To provide new evidence of the bird’s evolution.
B、To give new clues to the origins of dinosaur.
C、To prove dinosaur and squirrel are relatives.
D、To support the idea of birds deriving from dinosaur.
答案
A
解析
主旨题。题目中的significance是“重大意义”的意思。事实上,新闻中的一开始就谈到“……他们称这为研究鸟类的起源提供了新的线索”。而且在后面讨论的就是鸟是从生活在地上的恐龙还是从生活在树上的动物进化而来的问题。因此,A为正确选项。
