问题     Doctors are researching the health benefits of red wine, specifically the apparently wondrous powers of resveratrol, a polyphenol that is found in the skin of grapes and is thought to prevent illness and promote longevity. This wasn’t the first time "60 Minutes" trumpeting the virtues of red wine; in 1991, it called attention to the so-called French Paradox, which assumed that the low rate of heart disease in France, despite a national diet gloriously abundant in rich foods, was due to the country’s huge consumption of red wine. That report fanned an obsessive interest in the nutritional and therapeutic properties of wine. This seems to be a particularly American fixation, and it raises an intriguing question: Why are we—Americans—so anxious to find justifications for drinking wine beyond the fact that it tastes good and we like it?
    Obviously, scientists aren’t investigating wine’s physiological impact because they are camouflage for the wine industry and want to encourage Americans to drink; the research is being pursued and the results disseminated because it appears that there really is a link between red wine and well-being. It is now widely recognized that moderate red wine consumption—generally defined as one or two 5-ounce glasses a day for women and two or three for men, drunk with food—increases HDL cholesterol, the "good" cholesterol that removes fatty deposits from arteries. In addition, scientists have determined that the flavonoids in red wine have an anticoagulant effect that can help prevent blood clots leading to heart attacks.
    Resveratrol is also said to have a role in preventing clots and is believed to inhibit the production of LDL cholesterol—the bad kind. Resveratrol seems to be the omnipotent ingredient in red wine— a "vascular pipe-cleaner," as Dr. Christoph Westphal and Harvard biochemist David Sinclair put it, whose research suggests that resveratrol can delay the aging process and prevent many gerontological diseases. A few years ago, scientists reported that resveratrol may discourage the onset of one such illness, Alzheimer’s. It is also claimed that this antioxidant can boost stamina, reduce lung inflammation stemming from chronic pulmonary disease, and help prevent cancer. In the fall of 2008, University of Pittsburgh scientists even reported that resveratrol might offer some protection against radiation poisoning.
By mentioning the French Paradox, the author intends to______.
选项 A、prove the polyphenol in red wine can prevent illness and promote longevity
B、demonstrate a program has paid attention to the value of red wine long before
C、state Americans have an obsessive interest in red wine’s benefit
D、explain the reason for Americans’ fixation for red wine’s function
答案B
解析 属信息推断题。选项A属于无关干扰，利用原文第一句关键词捏造信息，从文中无法推知，故错误。选项C和D均犯了答非所问的错误，两个选项中的内容确实符合原文，但并非作者提到这个报告的意图，故错误。作者的真正意图可在第二句中找到答案，作者表示《60分钟》这个栏目已经不是第一次宣传红酒的价值了，因此可知选项B符合题意。
