问题     Women are considered "heavy drinkers" if they have eight or more drinks a week, according to the Centres for Disease Control and Prevention. Men can have 14. At 15, you, my friend, are a "heavy drinker" in the eyes of the CDC.
    One in 10 deaths among adults between the ages of 20 and 64 are due to excessive alcohol con sumption, the CDC says in a report released Wednesday. That means some 80,000 people die a year as a result of drinking too much. The majority of those are men—about 70%.
    Do you consider yourself a light, moderate or heavy drinker? Health agencies have these definitions to help you understand when your drinking may become a health problem.
    "The definition of ’heavy drinker’ has evolved over the last 20 years and it is based on scien tific evidence about the harmful consequences of drinking too much," says George F. Koob, director of the National Institute on Alcohol Abuse and Alcoholism, who has sat on the committees that create those definitions.
    The definition on NIAAA’ s website of "heavy" or "at-risk" drinking is the same as the CDC’ s. But the National Survey on Drug Use and Health has another. They say "heavy use" is "five or more drinks on the same occasion, on each of five or more days in the past 30 days."
    "It’s imprecise and not quantitative. I try to avoid using terms like ’heavy’, ’light’ and ’moderate’ for that reason in my publications," says Dr. Arthur Klatsky who has been studying alcohol and its impact on humans for decades. "The problem is everyone always wants to know if they fit into one of those categories."
    Heavy drinking can lead to chronic diseases, including problems with your liver, and throat. It can lead to high blood pressure, psychological problems. It even puts you at an increased risk for becoming a victim of violence. And of course you ultimately risk becoming an alcoholic.
    Klatsky says the pattern of when you drink is just as important to your health as the total number. Abstaining much of the week and then having all seven drinks on Saturday is also bad for your health.
    Studies show the mortality rate for people who drink moderately on a daily basis is actually lower than those who don’t indulge. There are health benefits to a lower level of drinking.
Why Dr. Arthur Klatsky didn’t use terms like "heavy", "light" and "moderate" in his publications?
选项 A、They are neither precise nor quantitative.
B、They are misleading.
C、They are too general.
D、They are not specific.
答案A
解析 推断题。根据题干中的Dr．Arthur Klatsky可以定位到文中It’s imprecise and not quantitative．I try to avoid using terms like‘heavy’，‘light’and‘moderate’for that reason in my publications(我一般在我的出版物中试着避免使用‘重度“中度’和‘轻度’这些术语，因为它们不精确，难以量化)。可知他不用这些术语的原因是它们不精确，不能量化。因此，正确答案是A。
