以下是引用lemonee在2003-9-12 10:15:00的发言: 4. Some anthropologists study modern-day societies of foragers in an effort to learn about our ancient ancestors who were also foragers. A flaw in this strategy is that forager societies are extremely varied. Indeed, any forager society with which anthropologists are familiar has had considerable contact with modern nonforager societies.
真确答案是a。做是作对了,可觉得不踏实。 第一句话是fact .第二句是conclusion. 第三句是support conclusion. 可让我想不明白的是considerable contact with modern nonforager societies.的作用 请哪位指点!谢谢
同问。 最后一句话的作用是什么??? |
