问题     A New website from the U.S. Department of Agriculture(USDA)shows that 10 percent of the country is now a "food desert." The Food Desert Locator is an online map highlighting thousands of areas where, the USDA says, low-income families have little or no access to healthy fresh food. First identified in Scotland in the 1990s, food deserts have come to symbolize urban decay. They suggest images of endless fast-food restaurants and convenience stores serving fatty, sugary junk food to overweight customers who have never tasted a Brussels sprout.
    Accordingly, Michelle Obama announced a $400m Healthy Food Financing Initiative last year with the aim of eliminating food deserts nationwide by 2017. Official figures for the number of people living in food deserts already show a decline, from 23.5m in 2009 to 13.5m at the launch of the website. Although this might on the face of it suggest that the initiative is off to a superb start, sadly it does not in fact represent a single additional banana bought or soda escaped. This is because in America, the definition of a food desert is any census area where at least 20 percent of inhabitants are below the poverty line and 33 percent live more than a mile from a supermarket. By simply extending the cutoff in rural areas to ten miles, the USDA managed to rescue 10m people from desert life.
    Some academics would go further, calling the appearance of many food deserts nothing but a mirage. Research by the Centre for Public Health Nutrition at the University of Washington found that only 15 percent of people shopped for food within their own census area. Critics also note that focusing on supermarkets means that the USDA ignores tens of thousands of larger and smaller retailers, farmers’ markets and roadside greengrocers, many of which are excellent sources of fresh food. Together, they account for more than half of the country’s trillion-dollar retail food market.
    A visit to Renton, a depressed suburb of Seattle, demonstrates the problem. The town sits directly in the middle of a USDA food desert stretching miles in every direction. Yet it is home to a roadside stand serving organic fruit and vegetables, a health-food shop packed with nutritious grains and a superstore that researchers found attracts flocks of shoppers from well outside the desert.
According to the USDA, food deserts______.
选项 A、tend to be found in poor rural areas
B、refer to the places with a food shortage
C、are directly related to urban poverty
D、are the direct cause of overweight
答案C
解析 第一段介绍了什么是“食物沙漠”。这一概念源自苏格兰，代表着城市的衰落。美国的定义就是指低收人家庭很少或没有机会食用健康新鲜食物的地区。所以“食物沙漠”与城市中的贫困是直接相关的。
