　　The discovery of a dwarfed (矮个的)"human being" who lived in Flores, Indonesia, up to 18,000 years ago is changing the way we think about the human family. This "Flores Human"wasthree foot tall and her brain was smaller than that of the average chimp(黑猩猩) ,yet she and herrelatives apparently lived fully human lives. They seem to have made tools, worked together to findfd and cook it, and perhaps even burried their dead with ceremony.

　　It was a major surprise to find tools associated with the new human family member. The tools arelike those formerly seen only with European fossils (化石)from our own species;Homo sapiens (智人) ;and the oldest of them were made 9,400 years ago. Homo sapiens is thought to have arrived inthe island about 4,000 years ago, much too late to be responsible for the tools. If this tiny humanmade the tools, then the inside structure (结构)of its brain must have been more like our own than a chimp's, despite being just a third the size of ours.

　　This "new human" was suspected to be a dwarfed branch of Homo erectus( 直立人). When crea-tures are separated in regions with rare resources but few enemies, being big is a disadvantage, andevolution tends to shrink them, a process known as island dwafng. Could natural selection make a hu-man smaller while keeping--even improving--mental ability? Quite possibly, believes ChristopherWills of the University of California.

　　Has the "Flores Human" even shown the ability of language? "I find it difficult to imagine thatpeople could make tools, use fire, and kill large animals without fairly advanced communication," Willssays. Did "Flores Human" possess the basic components of human culture--such as the burying of thedead with ceremony? Emiliano Bruner of the Italian Institute points out that Indonesia's hot,wet envi-ronment is bad for fossilization. It is reasonable to assume,he says,that the 18,000-year-old bones ofthe most complete Flores woman were well-preserved because she was buried with special care.

　　Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopesto watch dinosaurs in order to know how they lived and whether they were good parents. Instead, theyhave to search hard for information from dinosaurs' fossils (恐龙化石)because dinosaurs died outmillions of years ago.

　　It's very difficult for the scientists to reach an agreement because different results can be gotfrom the same fossils. Many fossils of the same kind of dinosaurs have been dug out from oneplace. They might have formed when an entire group of dinosaurs got stuck (陷人) all at once. Orthey might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and inthe second lived alone.

　　Though there are two different results, dinosaur scientists now generally agree tha~" at least somekinds of dinosaurs lived in big groups. "That's pretty much settled at this point," says Paul Sereno.A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear torun north and south, suggesting that they even moved long distances together.

　　As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest liv-ing relatives of dinosaurs--birds and crocodiles--for possible models. Birds give a lot of care to theiryoung, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sittingon their eggs and staying with their young suggest the parents were taking care of their babies, but westill cannot say that all dinosaurs did the same.

　　There is still a long way to go before the above questions could be answered. Dinosaur scientists

　　will have to find more proof to reach an agreement.

　　52Dinosaur scientists can get information directly by ____________ .

　　A.studying dinosaur fossilsB.examinipg modern animalsC.watching dinosaursD.using tel'es~opes

　　参考答案：A

　　参考解析：

　　根据第一段第二句研究恐龙化石可得到直接信息，故A项正确。

　　53What is pretty much settled according to Paul Sereno?

　　A.Half of the dinosaurs lived alone.B.Most dinosaurs moved long distances.C.Many dinosaurs settled in the north.D.Some dinosaurs lived in big groups.

　　参考答案：D

　　参考解析：

　　根据Paul Seren0所说的话可知that指的是上文提到的内容，再结合本段第一句话可判断D项正确。

　　54Dinosaur scientists can probably know whether dinosaurs were good parents by __________ .

　　A.watching many kinds of animalsB.studying dinosaurs' living relativesC.following the tracks left behindD.working on dug-out dinosaur eggs

　　参考答案：B

　　参考解析：

　　根据倒数第二段第一句的后半句可知B项正确。

　　55Which of the following is TRUE according to the 4th paragraph?

　　A.Birds hardly pay attention to their young.B.Baby crocodiles can look after themselves well.C.Some dinosaurs took care of their young.D.Birds and crocodiles take good care of their young.

　　参考答案：C

　　参考解析：

　　根据本段最后一句可知人们还不能确信所有的恐龙都会照顾它们的后代，由此可判断C项正确。
