单选题To understand the marketing concept, it is only necessary to understand the difference between marketing and selling. Not too many years ago, most industries concentrated primarily on the 1 production of goods, and then 2 on "persuasive salesmanship" to move as much of these goods as possible. Such production and selling focuses on the needs of the seller to produce goods and then 3 them into money. Marketing, on the other hand, focuses on the wants of consumers. It begins with first analyzing the 4 and demands of consumers and then producing goods that will 5 them. This eye-on-the-consumer 6 is known as the marketing concept, which simply means that instead of trying to sell 7 is easiest to produce or buy for resale, the makers and dealers first try to find out what the consumer wants to buy and then go 8 making it available for purchase. Every 9 —design, production, distribution, promotion—is made according to consumer demand. This concept does not 10 that consumer satisfaction is given 11 over profit in a company. There are always two 12 to every business activity—the firm and the customer—and each must be satisfied before trade 13 .

This concept has been recognized in such slogans as "Have It Your Way", and "Your are the boss".

单选题Faith in medicine runs deep in America. We spend more per person on health care than any other nation. Whether we eat too much or exercise too little, whether we"re turning gray or feeling blue, we look to some pill or procedure to make us better. We assume that devoting ever more dollars to medicine will bring us longer, healthier lives. But there is mounting evidence that each new dollar we devote to the current health care system brings small and diminishing returns to public health. Today the United States spends more than $4 500 per person per year on health care. Costa Rica spends less than $ 300. Yet life expectancy at birth is nearly identical in both countries. Despite the highly publicized" longevity revolution," life expectancy among the elderly in the United States is hardly improving. Yes, we are an aging society, but primarily because of falling birthrates. Younger Americans, meanwhile, are far more likely to be disabled than they were 20 years ago. Most affected are people in their thirties, whose disability rates increased by nearly 130 percent, due primarily to overweight. Why has our huge investment in health care left us so unhealthy? Partly it is because so many promised" miracle cures," from Interferon to gene therapies, have proven to be ineffective or even dangerous. Partly it"s because health care dollars are so concentrated on the terminally ill and the very old that even when medical interventions "work,"" the gains to average life expectancy are small. And partly it is because of medical errors and adverse reaction to prescription drugs, which cause more deaths than motor vehicle accidents, breast cancer or AIDS. Each year roughly 200 000 seniors suffer fatal or life-threatening "adverse drug events" due to improper drug use or drug interaction. Why don"t Americans live any longer than Costa Ricans? Overwhelmingly, it"s because of differences in behavior. Americans exercise less, eat more, drive more, smoke more, and lead more socially isolated lives. Even at its best, modern medicine can do little to promote productive aging, because by the time most people come in contact with it their bodies are already compromised by stress, indulgent habits, environmental dangers and injuries.

单选题One of the most widely discussed subjects these days is. energy crisis. Automobile drivers cannot get gasoline; homeowners may not get enough heating oil; factories are (56) by a fuel shortage. The crisis has (57) questions about the large oil companies and windfall (58) . Critics of the oil industry charge that the major companies are getting richer because of the oil shortage. Shortage, of course, drives prices up. As oil prices rise, the critics say, the oil companies will make more money (windfall profits) without doing a thing to (59) the extra cash. "Windfall" profits are sudden unearned profits--profits made (60) luck, or some special turn of events. The word itself tells what "windfall" means--something blown down by the wind, such as trees, or fruit (61) from trees. But the word has taken on a special meaning. This meaning (getting something unearned) was first used in medieval England. This is (62) it started: at that time much of the land was in the hands of (63) barons. The rest of the people, commoners, lived and worked on their vast estates. They planted the seed, cared for the farm animals and harvested the crops. Not all the land, however, was used for farming. Every baron kept a large private forest for (64) deer and wild bear. When hungry, the people sometimes would kill the animals in the lord's forest for food. And there were times (65) they might cut down trees for fuel. So, strong laws were passed to protect the forests, and the animals. Violations were severely (66) . But there was one way people could get wood from the forest. If they found trees blown down by the wind ("windfall") they were free to take them for use as fuel in their homes. And that is the meaning that has come down to us--something good gotten by luck or (67) . The common people of old England, often hungry and cold, must often have prayed for a good strong wind. Critics today (68) that the oil industry has also been praying for something just like it --some political or military (69) that might produce a windfall--a rise in oil prices and profits. The oil companies deny that this is so. In Congress, critics of the oil companies have proposed a (70) on such profits. The debate on rising oil price will go on for some time, and most likely we will hear more and more about windfall profits.
