问题     There is nothing like the joy of finding out that something sinful is actually good for you, whether it’s sex, chocolate or a glass of fine red wine—or, for that matter, beer, whisky or a satisfying aperitif. We’ve long heard exciting hints that red wine has unique benefits for the heart. But the same sunny reputation for heart health is now starting to shine on all liquor. " No matter where you look, the dominant alcoholic beverage is beneficial—whether it’s red wine in France and Italy, sake in Japan or beer in Germany," says Dr. Walter Willett, chair of nutrition at the Harvard School of Public Health.
    This has led researchers to an inescapable conclusion. As healthful as components of red wine may be, the primary benefit must come from ethanol itself. In short, it’s the alcohol, stupid. But don’t go overboard. Protection comes only with light to moderate intake—two drinks a day for men or a miserly one a day for women.
    The major benefit of alcohol seems to come from its ability to boost levels of HDL, the good cholesterol that helps keep arteries clear of plaque. Ethanol does that by signaling the liver to make more of a substance called Apo Al, the major protein in HDL. The effects can be striking. "Depending on the individual, you can get increases of 10 to 30 percent in HDL in a week," says Harvard epidemiologist Eric Rimm. Alcohol also makes blood less sticky and less likely to form clots that cause heart attacks and strokes. It also appears to have mild anti-inflammatory effects. And it enhances insulin sensitivity—which may explain why moderate alcohol consumption correlates with a lower incidence of type 2 diabetes.
    But alcohol is a dietary Jekyll and Hyde. Heavy intake can raise blood pressure, increase irregular heartbeat, and lead to heart failure. The most sobering news concerns cancer. A recent analysis of 156 studies found that as alcohol intake increases, so do risks of tumors in the mouth, and liver. Even moderate drinking can boost breast-cancer risk a small amount.
    Is moderate drinking worth the risks? For some people—pregnant women, people with liver disease or a history of alcoholism—the answer is no. But for most of us, the benefits will probably outweigh the hazards. Whether you sip wine, beer or spirits, your heart may thank you.  
According to Dr. Walter Willett, for good health, people could drink______.
选项 A、only red-wine
B、beer
C、some whisky
D、any alcohol
答案D
解析 细节题。根据题干中的Dr．Walter Willett定位至首段末句引语处，Walter指出：无论是法国或意大利的红酒、日本的米酒还是德国的啤酒，酒精饮料都是有益的。这是对前一句the same sunny reputationfor heart health is now starting to shine on all liquor的说明，故[D]为答案。红酒、啤酒和威士忌都是首句中提到的不同酒类，虽然对人体都有益，但不全面，因此排除其他三项。
