问题     Here is a great irony of 21st century global health: while many hundreds of millions of people lack adequate food as a result of economic inequities, political corruption, or warfare, many hundreds of millions more are overweight to the point of increased risk of diet-related chronic diseases. Obesity is a worldwide phenomenon, affecting children as well as adults and forcing all but the poorest countries to divert scarce resources away from food security to take care of people with preventable heart disease and diabetes.
    To reverse the obesity epidemic, we must address the fundamental cause. Overweight comes from consuming more food energy than is expended in activity. The cause of this imbalance also is ironically improved prosperity. People use extra income to eat more and be less physically active. Market economies encourage this. They turn people with expendable income into consumers of aggressively marketed foods that are high in energy but low in nutritional value, and of cars, television sets, and computers that promote sedentary behavior. Gaining weight is good business. Food is particularly big business because everyone eats.
    Moreover, food is so overproduced that many countries especially the rich ones, have far more than they need — another irony. In the United States, to take an extreme example, most adults — of all ages, incomes, educational levels, and census categories — are overweight. The U. S. food supply provides 3800 kilocalories per person per day, nearly twice as much as required by many adults. Overabundant food forces companies to compete for sales through advertising, health claims, new products, larger portions, and campaigns directed towards children. Food marketing promotes weight gain. Indeed, it is difficult to think of any major industry that might benefit if people eat less food; certainly not the agriculture, food product, grocery, restaurant, diet, or drug industries. All flourish when people eat more, and all employ armies of lobbyists to discourage governments from doing anything to inhibit overeating.
To address the fundamental cause of the obesity epidemic, according to the passage, is______.
选项 A、to improve political and economic management
B、to cope with the energy imbalance issue
C、to combat diet-related chronic diseases
D、to increase investment in global health
答案B
解析 主旨题。本题题意是：“根据本段文字，谈论造成肥胖病的基本原因就是要对付能量不平衡问题。”因为本段文字频繁出现irony一词，并将贫穷与肥胖原因进行对照，可以判断作者是不满于能量不平衡的。所以选B。
