2.OG的变体-鸟类是恐龙那道题 （缺原题）
类似有关鸟类和恐龙的题（by lestatwn）
V1：
Recently discovered fossil evidence casts doubt on the evolutionary theory that dinosaurs are more closely related to reptiles than to other classes of animals. Fossils show that some dinosaurs had hollow bones-a feature found today only in warm blooded creatures, such as birds, that have a high metabolic rates. Dinosaurs had well-developed senses of sight and hearing, which is not true of present-day cold blooded creatures like reptiles. The highly arched mouth roof of some dinosaurs would have permitted them to breathe while eating, as fast –breathing animals, such as birds, need to do.Today all fast-breathing animals are warm blooded. Finally, fossils reveal that many dinosaurs had a pattern of growth typical of warm-blooded animals.
The argument in the passage proceeds by
(A)Attempting to justify one position by demonstrating that an opposition is based on erroneous information.
(B)Establishing a general principle that it then uses to draw a conclusion
about a particular case
(C)Dismissing a claim made about the present on the basis of historical
evidence
(D)Assuming that if all members of a category have a certain property then all things with that property belong to the category
(E)Presenting evidence that a past phenomenon is more similar to one than the other of two present day
V2：
Paleontologists hypothesize that modern birds evolved from the family of dinosaurs that included Tyrannosaurus rex. This hypothesis would be strongly supported if evidence that dinosaurs from this family had a body covering resembling feathers could be found, but so far no such evidence has been found. Which of the following, if true, would most help the paleontologists explain why no evidence of feathered dinosaurs has yet been found?
1.Fossilized dinosaurs have shown many birdlike characteristics, such as bone structure and wing like arms.
2.If birds are in fact the descendants of dinosaurs, then it can be argued that the dinosaurs never really died out.
3.Flying dinosaurs such as the Pteranodon, which is not thought to have been related to modern birds, do not appear to have had feathers.
4.Soft tissues such as skin and feathers do not fossilize like bones, and therefore are far less likely to have left permanent evidence in the fossil record.
5.The thousands of dinosaur fossils excavated by paleontologists represent only a tiny fraction of the billions of dinosaurs that once lived.
