Passage Two

 听力原文

    (12) [The idea to study the American Indian tribe, Tarahumaras, came to James Copeland in 1984, when he discovered that very little research had been done on their language.] He contacted a tribe member through a social worker who worked with the tribesmen in Mexico. At first, the tribe member, named Gonzalez, was very reluctant to cooperate. He told Copeland that no amount of money could buy his language. But after Copeland explained to him what he intended to do with his research and how it would benefit the Tarahumaras, Gonzalez agreed to help. (13) [He took Copeland to his village and served as an intermediary.] Copeland says: “Thanks to him, the Tarahumaras understood what our mission was and started trusting us.” 

    (14) [Entering the world of the Tarahumaras has been a laborious project for Copeland.] To reach their homeland, he must drive two and a half days from Houston, Texas. He loads up his vehicle with goods that the tribesmen can’t easily get and gives the goods to them as a gesture of friendship. The Tarahumaras, who don’t believe in accumulating wealth, take the food and share it among themselves.

    For Copeland, the experience has not only been academically satisfying, but also has enriched his life in several ways. “I see people rejecting technology and living a very hard, traditional life, which offers me another notion about the meaning of progress in the western tradition,” he says. “I experience the simplicity of living in nature that I would otherwise only be able to read about. (15) [I see a lot of beauty in their sense of sharing and concern for each other.”]

13. How did Gonzalez help James Copeland?

解析：D。录音前半部分提到，冈萨雷斯同意帮忙。他把科普兰带到他的村子里，并当起了中间人的角色，D项与此内容相符，其中acted as an intermediary是对录音中served as an intermediary的同义替换，故D项为正确答案。

错项排除：录音中虽然提到了“语言”（languages）和“赠送礼物”（gives the goods to them），但“教授语言”（taught language）和“说服”（persuaded）在录音中并未体现，A项和B项是利用录音中的个别单词进行干扰，故均排除。C项中的one of his best friends在录音中未提及，故排除。
