单选题The organization known to the world as Interpol has sometimes been described as an outfit of chisel-jawed gimlet-eyed crime fighters who put their lives in jeopardy every working hour. Less flatteringly, Interpol has also been described as a huge filing cabinet, stuffed with clerks choking on their own statistics. As with most generalities, there is some truth in both statements. There are, certainly, some grim battlers of crime to be found working with Interpol. There are, just as surely, those drones shuffling mountains of paper whose cheeks are sallow from indoor life. Consider the charisma of the name alone: INTERPOL, the international police force. Continents leaped in a single bound, oceans crossed in the space of a breath, villains watched by eyes that never sleep. Surprisingly, a lot of it happens almost that way. Four groups coordinate and direct the activities of Interpol. One of them is the National Central Bureaus, or NCBs, bodies designated by the member nations to serve as their link with Interpol. These are the front-line troops, the action people. In the United States, the Treasury Departments the National Central Bureau. In the United Kingdom, it is Scotland Yard; the Questura in Italy and the Melbourne City Police in Australia. Because police organization varies from country, the NCBs were established to act as the one special group to handle Interpol chores and unsure maximum cooperation between nations. Each NCB is usually an official government body with police powers if a country has only one central police authority, that body becomes the National Centre Bureau. Of course, any service appointed as an NCB is bound to its nation's law and authority and retains its national title. Each NCB is connected by radio to the regional station for its geographic zone. The regional stations are connected to the Central Station in France. The radio network is versatile. Network stations can monitor the Central station or any regional station. Because of this messages can be broadcast to more than one station at a time. A coding system determines the urgency of each message so that those with high priority can be given precedence. Besides, other communication tools, such as radio-teleprinters and phototelegraphy equipment. Permit rapid transfers of fingerprints and photographs. Sometimes ever more advanced technology is employed. When the police all over the world were looking for a Canadian named George Leray, they turned to the Early Bird Satellite. Leray had led his gang on a daring holdup of a Montreal bank and gotten away with $ 4 million. Scotland Yard broadcast Leray's photo to the world by satellite. An American who saw the picture in Florida recognized Leray as a man who was living on a yacht in Fort Lauderdale under an assumed name. The police were alerted and arrested Leray.

单选题The long, wet summer here in the northeastern U.S. notwithstanding, there's a world shortage of pure, fresh water. As demand for water hits the limits of finite supply, potential conflicts are brewing between nations that share transboundary freshwater reserves. Many people ask why we cannot simply take it from the sea, using our sophisticated technology of desalinization. But a good water supply must be hygienically safe and pleasant tasting and water containing salt would corrode machinery used in manufacturing in addition to producing chemical impurities. Since more than 95% of our water sits in the salty seas, man is left to face the reality that most water on the surface of the earth is not available for us. One very feasible way of sustaining our supply of freshwater is to protect the ecology of our mountains. Mountains and water go together, a fact to which Secretary General Kofi Annan has drawn attention more than once. From 30% to 60% of downstream fresh water in humid areas and up to 95% in arid and semi-arid environments are supplied by mountains. Without interference nature has its own way of purifying water — even though chlorination and filtration are still necessary as a precaution. In a mountainous area, aeration, due to turbulent flow and waterfalls, causes an exchange of gases between the atmosphere and the water. Agriculture, industry, hydroelectric generators and homes that need water to drink and for domestic use depend on these resources and, thus, we must protect mountainous areas as a means of survival.

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 ( mostlytelevision) 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.
