阅读理解     More than 20 years ago, a skeleton called Little Foot turned up in a South African cave. The nearly complete skeleton was a member of the human family. Now researchers have freed most of the skeleton from its stony shell and analyzed the fossils (化石) and they say 3.67-million-years-old Little Foot belonged to a unique species.     Researcher Ronald Clarke and his colleagues think Little Foot belonged to A. Prometheus (普罗米修斯南猿). Clarke works at the university of the Witwatersrand in Johannesburg South Africa. He studies fossilized humans and our relatives. Their foundings, published in four papers, have suggested the species A.Prometheus might have existed. Clarke has believed in that species for more than a decade, he found the first Little Foot's remains in a storage box of fossils in 1994. People began digging out the rest of the skeleton in 1997.     Many other researchers instead argue that Little Foot likely belonged to a different species, which is known as A.africanus (南方古猿非洲种). Researcher Raymond Dart first identified A.africanus in 1924. He was studying the skull (头颅骨) of an ancient youngster called the Taung Child. Since then, people have turned up hundreds more A. africanus fossils in South African caves. Those include Sterkfontein, where Little Foot was found.     The braincase is the part of the skull that holds the brain. And researchers found a partial braincase that Dart thought belonged to a different species in Makapansgat, one of those other caves. In 1948, Dart called this other species A. Prometheus, but he changed his mind after 1955. Instead, he said that braincase and another fossil at Makapansgat belonged to A.africanus. There was no A. Prometheus after all, he concluded.     Clarke and his colleagues want to bring back the rejected species. They say Little Foot's distinctive skeleton, an adult female that is at least 90 percent complete, is solid evidence for it. （1） Which of the following beliefs did Ronald Clarke hold? A . A.Prometheus wasn't a human species. B . Little Foot didn't belonged to the human family. C . Little Foot was one member of A.Prometheus. D . A.Prometheus lived over four million years ago. （2） What can we learn about A. Prometheus? A . There wasn't much evidence of it. B . Its fossil were first discovered in 1948. C . It's a species that's believed to have existed. D . The Taung Child wasn't its first known member. （3） What's Dart's most probable attitude toward the existence of A. Prometheus now? A . Uncertain B . Supportive C . Uninterested D . Disapproving （4） What is the best title for the text? A . The Skeleton Little Foot Causing a Big Debate. B . Two New Human Species Accidentally Discovered. C . More Human Fossils Being Dug Up In Sterkfonte in. D . Little Foot From Makapansgat Drawing New Attention. 答案： C C D A
