Fire, scientists agree, helped give rise to a successful, thriving human population by providing heat for cooking and protection from the cold.
But they don’t agree【C1】______when humans began using fire. Some researchers argue that it【C2】______more than a million years ago when early humans【C3】______their way to Europe from Africa, and【C4】______say it happened much later. Now, a new study reveals that humans did not【C5】______fire until about 400 000 years ago.
Two archaeologists(考古学家)in the US report their【C6】______in the current issue of the Proceedings of the National Academy of Sciences. They looked at excavation(发掘)reports and studies from 141 sites in Europe that were【C7】______1.2 million and 35 000 years old. They think there is no clear evidence of【C8】______fire use until about 400 000 years ago. In Africa,【C9】______there are several sites where there was evidence of fire, those may have been【C10】______fires that occurred in the African grassland.【C11】______, there are also sites older than 400 000 years in Europe that indicate the【C12】______of humans, with the oldest, in Spain, more than a million years old.

But some researchers【C17】______that it is still a puzzling explanation and it still【C18】______some serious thinking about how【C19】______the human being could have survived on a seasonally【C20】______food supply despite having small teeth and small guts. Up to now, no one has solved this problem yet. [br] 【C11】
选项
A、Furthermore
B、Therefore
C、Meanwhile
D、However
答案
D
解析
上文指出虽然新的研究表明人类用火最早可以推到40万年前,但是从下文得知,在欧洲出现了几处早于这个时间的火的遗址,所以前后是一种转折关系,因此选However。Furthermore“此外,而且”,表示递进关系;Therefore“于是,因此”,表示顺承关系;Meanwhile“与此同时”。表示并列关系。
