【定位】根据题干中的higher-level可把考点定于最后一段。
【解析】细节题。根据最后一段的第l句，随着体育项目的全球化发展，人们作为体育比赛的消费者也有了更多的选择，因此对体育比赛的水平也有了越来越高的要求。所以人们实际上是把体育比赛当成了消费品，花了钱就希望买到最好的商品．B符合文意，为正确选项。
【点睛】此题可能会误选为D，但首先文章中并没有特别提到体育比赛的“精彩和吸引入”与高水平比赛的关系，另外选项本身的提法也有一定问题，因为很明显不是所有的,sports events都很精彩、很吸引人，所以D不正确。

Scientists have determined that Archaeopteryx, the earliest known bird, was definitely birdbrained, meaning no disrespect. Indeed, they consider the fossil's brain size decisive evidence that Archaeopteryx had what it took to fly.
The new research suggests, moreover, that birds probably started flying millions of years earlier than scientists previously thought. It is just that fossils of those fast flying birds-predecessors of Archaeopteryx-have never been found.
The researchers, at the Natural History Museum in London, based their findings on the first X-ray examination and reconstruction of the braincase and inner ear of a 147-million-year-old Archaeopteryx specimen. They found that in size, shape and volume, its brain was similar to that of the modem eagle or sparrow.
Measurements of the semicircular canals, the mechanism for balance inside the ear, showed that Archaeopteryx had the “neurological and structural adaptations necessary for flight," the scientists concluded.
Their research, involving an X-ray computed tomography scan, or C.T., of the fossil's braincase and inner ear, is described today in the journal Nature.
Previous studies of the feathered wing and tail of Archaeopteryx and its birdlike anatomy, including a pronounced wishbone, supported the prevailing view of experts that it was capable of some degree of powered flight. Archaeopteryx is considered a prime transitional species in the evolution of some reptiles, probably dinosaurs, into today's birds.
But the research team, led by Dr. Angela Milner, a paleontologist at the British museum, wrote that until their investigation of Archaeopteryx, "little was understood about the extent to which its brain and special senses were adapted for flight."
Dr. Milner said the new study not only established that Archaeopteryx was capable of "controlling the complex business of flying," but also showed "how much there is still to discover about when and how bird flight began."
In a statement issued by the museum, Dr. Milner said, "If flight was this advanced by the time Archaeopteryx was around, then were birds actually flying millions of years earlier than we'd previously thought?"What is the original meaning of "birdbrained" and what does it mean here in the first paragraph?

A．Naive; intelligen
B．Simple-minded; volan
C．Narrow-minded; navigationa
D．Stupid; adapted for fligh
