Question 14 is based on the passage you have just heard.

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.”]

14. What does the speaker say about James Copeland’s trip to the Tarahumaras village?

解析：C。四个选项均为较难的形容词，推测本题很可能会用到视听一致原则。录音中提到，对科普兰来说，走进塔拉乌马拉人的世界是一项艰苦的工程（Entering the world of Tarahumaras has been a laborious project for Copeland）。其中laborious属于录音中的原词重现，故C项为正确答案。

错项排除：录音最后提到科普兰被村民之间的分享和关爱所触动，但并不能说明此次旅行是“不可预测的（unpredictable）”，A项过于牵强，故可排除。B项和D项在录音中都未提及，故排除。
