标题: CR: 史前人类迁徙 考古 [打印本页] 作者: iivion 时间: 2009-12-2 22:44 标题: CR: 史前人类迁徙 考古 我也不知道是不是原题，也不知道有人发过没，大家确认下一下哈： The first people to inhabit North America came from Asia. Scientists hypothesized that these people traveled across a now-submerged landmass that connected the two continents until 14,000 years ago, depending for food only on animals they hunted as they travelled. Recent discoveries have led to the new hypothesis that the first people came by bost along the southern shore of the landmass, eating fish and sea mammals. which of the following, if true, most strength the new hypothesis? A. the landmass connecting North America and Asia extended very far to the north.(无关项 B.In Europe, maritime culture 。。（无关） c. people living in Asia at the time the two countries were connected hunted land for food.( support the old hypothesis） D the landmass was so bitterly cold that its vegetation would have been too sparse to support animals.(support new hypothesis) E. 无关项作者: jenny1989 时间: 2009-12-2 22:51
谢谢LZ的提供考古啦 可是D选项和原狗狗作者提供得好像不大一样 大家也看看吧 科学家hypothesize that史前人类被推断是从北美大陆连接的部分从亚洲迁徙到了南美;在迁徙的路线中有鱼和猎物.问以下那个最能support such hypothesis. 选：那些迁徙的人类can catch the fish and hunt the game for food. OLD JJ 1. 就是讲亚洲人迁移到美洲?(不记得),有一个时期海洋里,冰川结合在一起,他们可以在那个时间迁移,而且有一些出土的化石证明有可以位他们提供食物的化石,例如三文鱼什么的,问评价 1)有研究证明这些人已经掌握了获取那些食物的技能 同意 2) 分析一下亚洲和美洲的基因.
