单选题For this part, you are required to write a composition on the topic Foods are overwhelmingly the most advertised group of all consumer products in the United States. Food products lead in expenditures for network and spot television advertisements, discount coupons, trading stamps, contests, and other forms of premium advertising. In other media- newspapers, magazines, newspaper supplements, billboards, and radio- food advertising expenditures rank near the top. Food manufacturers spend more on advertising than any other manufacturing group, and the nation's grocery stores rank first among all retailers. Throughout the 1970s, highly processed foods have accounted for the bulk of total advertising. Almost all coupons, electronic advertising, national printed media advertising, consumer premiums ( other than trading stamps) as well as most push promotion come from processed and packaged food products. In 1978, breakfast cereals, soft drinks, candy and other desserts, oils and salad dressings, coffee, and prepared foods accounted for only an estimated 20 percent of the consumer food dollar. Yet these items accounted for about one half of all media advertising. By contrast, highly perishable foods such as unprocessed meats, poultry, fish and eggs, fruits and vegetables, and dairy products accounted for over half of the consumer food-at-home dollar. Yet these products accounted for less than 8 percent of national media advertising in 1.978, and virtually no discount coupons. These products tend to be most heavily advertised by the retail sector in local newspapers, where they account for an estimated 40 percent of retail grocery newspaper ads. When measured against total food-at-home expenditures, total measured food advertising accounts for between 3 and 3.7 cents out of every dollar spent on food in the nation's grocery stores. A little less than one cent of this amount is accounted for by electronic advertising ( mostly television) while incentives account for 0.6 cents. The printed media accounts for 0.5 cents and about one-third of one cent is comprised of discount coupon redemptions. The estimate for the cost of push promotion ranges from 0.7 to 1.4 cents. This range is necessary because of the difficulty in separating non-promotional aspects of direct selling—transportation, technical, and other related services. Against this gross consumer cost must be weighed the joint products or services provided by advertising. In the case of electronic advertising, the consumer who views commercial television receives entertainment, while readers of magazines and newspapers receive reduced prices on these publication. The consumer pays directly for some premiums, but also receives nonfood merchandise as an incentive to purchase the product. The "benefits" must, therefore, be subtracted from the gross cost to the consumer to fully assess the net cost of advertising. Also significant are the impacts of advertising on food demand, nutrition, and competition among food manufacturers. The bulk of manufacturers advertising is concentrated on a small portion of consumer food products. Has advertising changed the consumption of these highly processed products relative to more perishable foods such as meats, produce, and dairy products? Has the nutritional content of U. S. food consumption been influenced by food advertising? Has competition among manufacturers and retailers been enhanced or weakened by advertising? These are important questions and warrant continued research.

单选题Among all the malignancies, lung cancer is the biggest killer; more than 100,000 Americans die of the disease. Giving up smoking is one of obvious ways to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by eating a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene. The finding, published in THE LANCET, is part of a long-range investigation of diet and disease. Since 1957, some American researchers have monitored the dietary habits and medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shekelle of St. Luke"s Medical Center, the researchers recently began to sort out the links between the subjects" dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offer some protection against lung cancer. The correlation seemed logical, explains Shekelle, since vitamin A is essential for the growth of the epithelial tissue that lines the airways of the lungs. Vegetables: But the earlier research did not distinguish between the two different forms of the vitamin. "Preformed" vitamin A, known as retinols found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples. In the study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A. But when they examined the data on carotene intake, they discovered a significant relationship. Among the 488 men who had the lowest level of carotene consumption, there were 14 cases of lung cancer; in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for long-time smokers—but to a lesser degree. Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balanced diet that includes goods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.
