问题     Some years ago two nutrition experts went grocery shopping. For a dollar, Adam Drewnowski and S. E. Specter could purchase 1,200 calories of potato chips or cookies or just 250 calories worth of carrots. This price difference did not spring into existence by force of any natural laws but largely because of antiquated agricultural policies. Public money is working at cross-purposes: backing an overabundance of unhealthful calories that are flooding our supermarkets and restaurants, while also battling obesity and the myriad illnesses that go with it. It is time to align our farm policies with our health policies.
    In past years farm subsidies have been a third rail of American politics—never to be touched. But their price tag, both direct and indirect, has now brought them back into the debate and created an imperative for change. Conditions such as heart disease, diabetes and arthritis are strongly correlated with excess poundage and run up medical bills of nearly $ 150 billion every year. The government has poured billions of dollars into dietary campaigns.
    Agricultural subsidies undercut those efforts by skewing the market in favor of unhealthful calories. Much of the food we have to choose from—and how much it costs—is determined by the 2008 farm bill. Federal support for agriculture, begun in earnest during the Great Depression, was originally intended as a temporary lifeline to farmers, paying them extra when crop prices were low. Nearly eight decades later the benefits flow primarily to large commodity producers of corn and soy, which are as profitable as ever.
    The current farm bill gives some $ 4. 9 billion a year in automatic payments to growers of such commodity crops as corn and soy, thus driving down prices for corn, corn-based products and corn-fed meats. Cows that are raised on corn, rather than grass, make meat that is higher in calories and contains more omega-6 fatty acids and fewer omega-3 fatty acids—a dangerous ratio that has been linked to heart disease.
    Cheap corn has also become a staple in highly processed foods, from sweetened breakfast cereals to soft drinks, that have been linked to an increase in the rate of type 2 diabetes, a condition that currently affects more than one in 12 American adults. Between 1985 and 2010 the price of beverages sweetened with high-fructose corn syrup dropped 24 percent. Over the same period the price of fresh fruits and vegetables rose 39 percent. For families on a budget, the price difference can be decisive in their food choices.
    There is no dearth of policy options. Research groups recommend leveling the playing field by extending subsidies and insurance programs more widely to fruit and vegetable producers. The government can also use its own purchasing power, through school lunch programs and institutional buying decisions, to fill people’s plates with healthy choices. The imperative, however, is clear; any new farm bill should at the very least remove the current perverse incentives for people to eat unhealthily.
Which of the following statement is true according to paragraphs 4 and 5?
选项 A、Type 2 diabetes relate more to highly processed diets than to minimally processed ones.
B、Omega-6 fatty acids are more correlated to heart disease than omega-3 fatty acids.
C、Corn-fed meats contains less calories than grass-fed meats.
D、Fruits and vegetables are in greater demand than corn and soy.
答案B
解析 [A]选项的误区在于对第五段首句的曲解。该句整体说明“谷物的深加工食品与2型糖尿病患病率的增长关系密切”，强调的是“多食谷物制品对健康不利”，并未涉及“深加工食品与粗加工食品”的差异，故选项错误。[C]选项是对第四段第二句的反向干扰：该句说明“谷饲肉类所含热量高于草饲肉类”。[D]选项的误区在于，考生可能会根据第五段第二、三句内容“谷物价格下降而果蔬价格大幅上涨”得出结论“果蔬需求量大于谷物”。但这种价格的差异足由不合理的农业补贴政策所导致的，并不能客观地反映市场的供求关系，因此无法判断果蔬和谷物的需求量哪个更大。
