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.
The underlined word in Paragraph 2 refers to______.

选项 A、experts
B、faking
C、influence
D、researching

答案B

解析 属词义推断题。单词所在句提到:科学家们不是在研究红酒的生理影响,他们为了让美国人多喝红酒,是在为红酒产业…。因此可知,他们不是真正地在做研究,而是为红酒产业假装做研究,目的就是为了让美国人多喝、多购买红酒,故选项B符合题意。选项A(专家)、选项C(影响)、选项D(研究)均不符合题意。
