问题     One of the most contentious issues in the vast literature about alcohol consumption has been the consistent finding that those who don’ t drink tend to die sooner than those who do. The standard Alcoholics Anonymous(匿名戒酒互助会)explanation for this finding is that many of those who show up as abstainers(戒酒者)in such research are actually former hard-core drunks who had already incurred health problems associated with drinking.
    But a new paper in the journal Alcoholism: Clinical and Experimental Research suggests that—for reasons that aren’t entirely clear—abstaining from alcohol does tend to increase one’ s risk of dying, even when you exclude former problem drinkers. The most shocking part is abstainers’ mortality rates are higher than those of heavy drinkers.
    Moderate drinking, which is defined as one to three drinks per day, is associated with the lowest mortality rates in alcohol studies. Moderate alcohol use(especially when the beverage of choice is red wine)is thought to improve heart health.
    But why would abstaining from alcohol lead to a shorter life? It’s true that those who abstain from alcohol tend to be from lower socioeconomic classes, since drinking can be expensive. And people of lower socioeconomic status have more life stressors— job and child-care worries that might not only keep them from the bottle but also cause stress-related illness over long periods.(They also don’t get the stress-reducing benefits of a drink or two after work.)
    But even after controlling for nearly all imaginable variables—socioeconomic status, level of physical activity, number of close friends, quality of social support and so on—the researchers(a six-member team led by psychologist Charles Holahan of the University of Texas at Austin)found that over a 20-year period, mortality rates were highest for those who were not current drinkers, regardless of whether they used to be alcoholics, second highest for heavy drinkers and lowest for moderate drinkers.
What do we know from the new paper in the journal Alcoholism: Clinical and Experimental Research?
选项 A、Abstaining from alcohol can lead to a happier life.
B、The mortality rate of former problem drinkers is the highest.
C、Researchers have explained the reason why abstainers face high risk of dying.
D、Comparing with the abstainers, heavy drinkers are at a lower risk of dying.
答案D
解析 细节题。短文第二段最后一句指出abstainers’mortality rates are higherthan those of heavy drinkers即戒酒者的死亡率高于酗酒者。故答案D正确。
