问题     Are wine drinkers healthier than beer drinkers? If that is the case, it may have less to do with their choice of drink than with what they eat with it.
    A new study found that shoppers who bought wine in supermarkets were much more likely to buy healthy foods like olives and low-fat cheese than beer buyers, who were more in favour of things like chips. Studies have linked a moderate amount of alcohol use with better health, and this is especially true when it comes to wine, which has components that may help prevent cancer and cardiovascular (心 血管的) disease. Still, it is possible that whatever health benefits wine drinkers enjoy actually result from overall better diets, some studies have suggested.
    The problem for researchers has been getting an accurate reading on people’s diets in general and alcohol use in particular. Those being surveyed often understate their alcohol use and overstate their consumption of healthy foods. So for this study, the researchers tracked the sale of wine and beer over a six-month period at 98 supermarkets, and then looked at what kinds of food the shoppers bought. One auther, Dr. Morten Gronbaek, said the researchers had expected to find differences in buying patterns, but not to the extent that they did.
    There are other reasons wine drinkers may be healthier than beer drinkers, the researchers said. Wine tends to be drunk with food, and in smaller amounts, they noted, possibly affecting how the body metabolizes (使新陈代谢) it. And wine drinkers tend to be better educated and better off financially than beer drinkers, factors that would also help account for their better health.
Researchers failed to get an accurate reading on people’s diets in general because______.
选项 A、people tend to overstate the consumption of foods
B、people tend to understate the alcohol use
C、people have different buying patterns
D、people have different dietary habits
答案B
解析 本题为细节题。本题是问研究人员没能得到大多数人准确的食谱的原因。从文中第三段“…overstate their consumption of healthy foods．”可以得知，选项A的“the consumption off oods”太笼统，应为“healthy foods”；选项B．的“understate the alcohol use”为正确答案。选项C．people have different buying patterns不是原因，而是调查的内容之一，但在实际调查中也没有达到预期的目标。选项D．people have different dietary habits则为—个事实，也不是原因。
