【正确答案】 D

【答案解析】[听力原文]
   Potato chips in Japan are being sold for 6 times their normal price. This is after the country's main manufacturer stopped sales due to a potato shortage. Storms and floods and its main potato growing region last year caused the worst harvest in more than 3 decades. Local media reports suggest Cal-bee and its main rival Koike-ya are halting almost 50 products.
   "We don't know when we'll be able to restart," a company spokesman said. Snack lovers are panic buying and many supermarket shelves are bare. Japanese laws limit the amount of imported potatoes that can be used in Japanese-made products. Japan says fear of disease is its main reason to block fresh imports. It still only allows potatoes from selected US states. This is only at certain times and on condition that they are processed at factories based near Japanese ports.
   But global warming has raised the possibility that domestic produce could be seriously affected by rare weather events more often.
   What problem is Japan facing?
本题问日本正面临什么问题。新闻开篇即指出，当前薯片在日本的售价是其正常售价的6倍，随后补充提到，日本主要生产商因为土豆短缺(due to a potato shortage)停止销售薯片之后，这种情况才发生。据此可知，日本当前面临的问题包括土豆短缺、主要生产商停售、薯片售价极高等问题。D“土豆供应不足”与新闻所述相符，Insufficient potato supply是对录音原词a potato shortage的同义替换。
   A“土豆种植量减少”在录音中未提及，排除。B“严重依赖进口”中的import复现了录音原词，但录音明确提到日本法律限制进口土豆(limit the amount of imported potatoes)，B与录音内容相矛盾，故排除。C“植物病害泛滥”利用录音原词disease制造干扰，根据录音可知，日本阻止土豆进口的主要原因是害怕病害；此外，录音中既没提到是哪种病害，也没有说明病害泛滥，故排除。
