【正确答案】 B

【答案解析】[试题分析] 本题考查考生对文章细节内容的理解能力。
[详细解答] 在文章第二段中，一位探险家说到：“In order to get along reasonably well an Eskimo must have at the tip of his tongue a vocabulary of more than 10，000 words，”即与爱斯基摩人交谈，必须掌握一万个以上的爱斯基摩词汇，而实际情况是，白人说的并非真正的European language，而是“an intercourse between Eskimos and whites，a jargon similar to the pidgin English used in China， with a vocabulary of from 300 to 600 uninflected words，most of them derived from Eskimo but some derived from English，Danish， Spanish，Hawaiian and other languages．”因此我们可知，白人所说的European language的实际词汇量与真正的European language的词汇量相比要小得多，故选B。
