张教授：智人是一种早期人种。最近在百万年前的智人遗址发现了烧焦的羚羊骨头碎片的化石。这说明人类在自己进化的早期就已经知道用火来烧肉了。李研究员：但是在同样的地方也同时发现了被烧焦的智人骨头碎片的化石。以下哪项最可能是李研究员所要说明的?（ ）A．百万年前森林大火的发生概率要远高于现代B．百万年前的智人不可能掌握取火用火的技能C．上述被发现的羚羊骨头不是被人控制的火烧焦的D．羚羊并不是智人所喜欢的食物

迄今为止，年代最久远的智人遗骸在非洲出现，距今大约20万年。据此，
很多科学家认为，人类起源于非洲，现代人的直系祖先——智人在约20
万年前于非洲完成进化后，然后在约15万年到20万年前，慢慢向北迁徙，
穿越中东到达欧洲和亚洲，逐步迁徙至世界其他地方。以下哪项如果为真，
最能反驳上述科学家的观点?A:现代智人，生活在旧石器时代晚期，大约距今4万年至1万年。我国境内，许多地方都有晚期智人化石或者文化遗址发现，地点数以百计
B: 在南美洲的一处考古发掘中，人们发现生活于大约17万年前的智人头骨化石
C: 智人具备了个体之间能够相互沟通、制定计划、解决种种困难问题的那种非凡的能力
D:在以色列特拉维夫以东12千米的Qesem洞穴中发现了8颗40万年前的智人牙齿，这是科学家迄今为止在全球发现的年代最为久远的智人遗骸

Passage Four
Thediscovery of a dwarfed（矮个子）"humanbeing"who lived in Flores,Indonesia,up to 18,000 years ago is changingthe way we think about the human family.This"Flores Human"was threefoot tall and her brain was smaller than that of the average chimp（黑猩猩）,yet she and her relatives apparently lived fully human lives.They seem to have made tools,worked together to find food and cook it,andperhaps even burried their dead with ceremony.
It was a major surprise to find tools associated with the newhuman family member.The tools are like those formerly seen only with Europeanfossils（化石）from our own species;Homo sapiens（智人）;and the oldest of them were made 9,400 years ago.Homo sapiens isthought to have arrived in the island about 4,000 years ago,much too late tobe responsible for the tools.If this tiny human made the tools,then theinside structure（结构）of its brain must have been morelike 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 ofHomo erectus（直立人,）.When creatures are separated in regionswith rare resources but few enemies,being big is a disadvantage,and evolutiontends to shrink them,a process known as island dwarfing.Could naturalselection make a human smaller while keeping--even improving--mental ability?Quite possibly,believes Christopher Wills of the University of California.
Has the"Flores Human"even shown the ability oflanguage?"I find it difficult to imagine that people could make tools,use fire,and kill large animals without fairly advanced communication,"Wills says.Did"Flores Human"possess the basic components of humanculture--such as the burying of the dead with ceremony?Emiliano Bruner of theItalian Institute points out that Indonesia′s hot,wet environment is bad forfossilization.It is reasonable to assume,he says,that the 18,000-year-oldbones of the most complete Flores woman were well-preserved because she wasburied with special care.
According to the passage,"Flores Human"__A.lived a partly human life
B.was a branch of Homo sapiens
C.used tools before Homo sapiens arrived
D.had a brain as large as a commonchimp's
