选项A 错，因为录音说的是Bowe Bergdahl被交给美方特种部队，用以交换 被拘押在美国Guantanamo Bay监狱的5 名阿富汗人，而不是说他是被拘押的阿富汗人。选 项 B 错，因为录音中完全没有关于他的具体身份与职位的介绍。选项C错，因为录音说的是人们认为（ He is believed）他自从2009年 6 月被扣为人质，这 当然是说他被阿富汗人抓捕，而不是被美国人抓捕。正确选项D 在录音中的对应内容是 He will be transferred to the main U.S. base in Afghanistan，即他将被转送到美军在阿富汗的主要基地。

[重点难点]
理解 handed over, in exchange for 和 transferred to 的意义。

[录音原文]
U.S. Sergeant Bowe Bergdahl was handed over to U.S. Special Forces in exchange for the release of five Afghan detainees from the U.S. prison at Guantanamo Bay. He is believed to have been held hostage since June 2009. He will be transferred to the main U.S. base in Afghanistan for medical evaluation, and then be moved to the U.S.
