Chapter 1: EARLY AMERICA
THE FIRST AMERICANS
At the height of the Ice Age, between 34,000 and 30,000 B.C., much of the world’s water was locked up in vast continental ice sheets. As a result, the Bering Sea was hundreds of meters below its current level, and a land bridge, known as Beringia, emerged between Asia and North America. At its peak, Beringia is thought to have been some 1,500 kilometers wide.

在冰河时代的高峰期，即公元前34000年至30000年之间，世界上大部分的水都被锁在巨大的大陆冰原中。因此，白令海比现在的水位低了几百米，亚洲和北美之间出现了一座陆桥，即白令亚。在其巅峰时期，白令亚被认为有大约1500公里宽。这里是一片湿润无树的苔原，上面布满了草木和植物，吸引了早期人类为生存而猎取的大型动物….

本书为英文版，92页，由于是给英语二语习得者的书，写作风格和托福的文章很像，言简意赅的介绍了美国的发展历史，值得细读！
