问题     America is changing its eating habits. As medical evidence mounts that we are indeed what we eat, consuming a healthier diet has become almost a national passion in the United States. The food-for-fitness phenomenon began in the late ’70s when a U.S. Senate Committee on nutrition reached grim conclusion that six out of the ten leading causes of death — such as heart disease, cancer, and stroke — might be linked to diet. The government issued dietary guidelines advising Americans to eat a variety of foods, maintain proper weight, and limit intake of fat, salt, sugar, and alcohol.
    For most Americans, what to eat is a matter of personal choice, rather than one of supply. An excellent nationwide food distribution system assures that fresh produce is readily available in all parts of the country, regardless of the season. Taking advantage of this abundance(充足), many people are forsaking traditional meat-and-potatoes fare(饮食)in favor of lighter meals of salads, fruits, and vegetables.
    The single most dramatic change in the American diet has been a reduction in consumption of animal fat, which is thought to increase the risk of heart disease and may contribute to the high U.S. incidence of breast and colon cancer. Margarine(a fatty solid butter substitute)and vegetable oils have replaced butter and lard(i.e. white fat from pigs that is used in cooking)in many homes, and half of all milk now drunk in the United States is low-fat. Fish and poultry(i.e. birds such as chickens and ducks kept on farms in order to produce meat)are increasingly popular sources of protein as consumption of red meat declines. The food industry has responded to concern about fat by producing leaner cuts of meat and cholesterol-free(不含胆固醇的)substitutes for eggs.
    One of the most significant trends in the American way of eating is the healthful change in restaurant food. "One of every two meals in the United States is eaten outside the home," says Donna Watson, President of the American Dietetic Association. "Restaurants are making special efforts to provide low-fat, low-salt, and low-calorie items." Salad bars, loaded with fresh greens and raw fruits and vegetables, are found everywhere, even alongside the burgers and French fries in fast-food restaurants.
    Most important, the focus on prudent diet has led to an unprecedented national quest for a healthier life style. Americans are smoking less, exercising more, and experimenting with new ways to conquer stress. Eating sensibly, they have discovered, is only one important route to good health.
What does the author say about the choice of food in the U.S.?
选项 A、People have more choices when fruits and vegetables are in season.
B、People prefer traditional foods to food which are very low in fat.
C、People tend to choose salads because vegetables are more readily available.
D、People can choose what they want thanks to the sufficient supply of food.
答案D
解析 第2段首句提到，对大多数美国人来说，吃什么是个人选择的问题，而不是供应的问题。由此可以推断，美国食物供应很充足，人们可以根据自己的爱好想吃什么就吃什么，故答案为D)。第2段第2句提到，一个很好的全国食品分配系统确保了新鲜的产品在全国各地都很容易获得，不受季节影响，A)与之矛盾，故排除。第2段第3句提到，很多人放弃传统的肉和土豆的饮食，选择沙拉、水果、蔬菜这些更清淡的饭菜，B)与之矛盾，故排除。人们选择沙拉并不是因为蔬菜更容易获得，故排除C)。
