问题 How much does the World Bank suppose to spend in facing the agricultural challenges?
A UN agency says there are major funding gaps in efforts to help the agricultural sector adapt to climate change. The Food and Agriculture Organization, the FAO, says this could affect food security. The warning comes as the UN Climate Change Conference continues in Cancun, Mexico.
    The World Bank estimates it will cost about $2.5 billion a year—for the next 40 years-to help agriculture in developing countries adapt to climate change. Other estimates say costs could run as high as $14 billion a year.
    However, the FAO says, "Available financing mechanisms are substantially insufficient to meet the climate change and food security challenges faced by the agricultural sector." This, despite the fact that the FAO says there are many examples of how agriculture can become more.

选项 A、$14 billion.
B、$40 billion.
C、$2.5 billion.
D、$25 billion.

答案C

解析 数字细节题。新闻中指出,世界银行估计在今后的40年时间里协助发展中国家的农业适应气候变化,每年得花费25个亿。而有些人认为每年的费用将高达140亿。本题是数字题,听音时可边看数字边选择。A项中的14是其他人的估计,B项40是需要耗费的时间,D项中的25是干扰项。故正确答案是C。
