问题     Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated.  Advocates of organic foods — a term whose meaning varies greatly — frequently proclaim that such products are safer and more nutritious than others.
    The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and from the basis for folklore.
    Almost daily the public is besieged by claims for "no aging" diets, new vitamins, and other wonder foods. These are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains, and the like.
    One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is a real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
What is the author’s attitude toward the claims made by advocates of health foods?
选项 A、Very enthusiastic.
B、Somewhat favorable.
C、Neutral.
D、Skeptical.
答案D
解析 观点理解题。做这样的题需要从文中找出能反映作者思想感情的线索词。如这篇文章中有"being debated"(第1段第2句)，第2段的however一词引出相反意见，紧接着Although，cost more...so...real cause for concern...道出自己的看法，因此不难判断出作者持的是怀疑态度，故口“怀疑的”正确。
