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.
Which of the following is one of the author’s points of view?
选项 A、Resveratrol can protect people from radiation poisoning.
B、Resveratrol can postpone aging process and prevent aging-related diseases.
C、Americans are particularly fascinated about the value of red wine.
D、The low rate of heart disease in France is owing to drinking red wine.
答案C
解析 属信息归纳题。选项A出现在文章最后一句，此观点是匹兹堡大学的科学家们提出的，并非作者观点，故错误。选项B出现在第三段第二句，是两位科学家的研究结果，也非作者观点，故错误。选线D出现在第一段，这个报告是《60分钟》栏目呼吁人们关注的，而作者并未对此观点做出评价，故错误。文章第一段第四句提到这种痴迷是美国人特有的，故选项C符合题意。
