    (3) [The village of Maref in Alaska voted on Tuesday to move to the state’s mainland.] The move is due to global warming and rising sea levels. Most of the village’s 169 registered voters took part in the town hall meeting. They decided in a vote of 89 to 78 to move from their land on Sarichef Island, near the Arctic Circle. Maref Council Secretary Donna Barr said the vote was largely symbolic. It will be costly financially to the community. “About 15 years ago, they estimated the cost at $180 million. I would figure it’s much higher now,” Barr said. (4) [“We don’t see the move happening in our lifetime because of the funding.”] The village’s roughly 650 residents have seen warming temperatures melt sea ice and permanently frozen land. This has resulted in houses falling into the water. At least 31 villages in Alaska face “immediate threats” due to climate change, the Government Accountability Office reported in 2009.

4. Why did Donna Barr say they wouldn’t see the plan carried out any time soon?（唐娜·巴尔为什么说他们可能无法看到计划很快得以落实？）

解析：B。录音中巴尔表示，大约在15年前他们就估算过，迁移要花费1.8亿美元。现在的费用要高得多。由于资金的问题，我们在有生之年可能都无法看到迁移实现。B项符合题意，为正确答案。

错项排除：录音中没有提及迁移所需的时间以及是否需要最后的批准，故排除A项和C项。录音中提到，投票结果是89比78决定迁移，也就是说89票赞成、78票反对，的确有一些村民反对迁移，但并没有说迁移是因为村民的反对而不能实行，故D项错误。
