16、ncept, it is only necessary to understand the differ ence between marketing and selling. Not too many years ago, most industries concentrated primarily on the efficient production of goods, and then relied on “persuasive salesman ship“ to move as much of these goods as possible. Such production and
17、selling focuses on the needs of the seller to produce goods and then convert them into money.Marketing, on the other hand, focuses on the wants of consumers. It begins with first analyzing the preferences and demands of consumers and then producing goods that will satisfy them. This eye-on-the-consu
18、mer approach is known as the marketing concept, which simply means that instead of trying to sell whatever 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 about making it according to consumer demand.This concept does n
19、ot imply that consumer satisfaction is given priority over profit in a company. There are always two sides to every business activity-the firm and the custom- erand each must be satisfied before trade occurs. Successful merchants and producers, however, recognize that the surest route to profit is t
20、hrough understanding customers. This concept has been recognized in such slogans as “Have It Your Way. “ and “Youre the Boss. “ A good example of the importance of satisfying the consumer presented itself in mid 1985, when Coca-Cola changed the flavor of its drink. The non-acceptance of the new flav
21、or by a significant portion of the public brought about a prompt restoration of the Clas sic Coke, which was then marketed alongside the new. King Customer ruled!（分数：5.00）(1).A good knowledge of the difference between marketing and selling leads to_.（分数：1.00）A.the efficient production of goodsB.a pe
22、rfect command of salesmanshipC.a basic command of the marketing conceptD.the conversion of goods into money(2).Not too long ago, industries focused on_.（分数：1.00）A.producing and selling goodsB.the needs and wants of customersC.the selling of new productsD.moving goods to the market(3).The very core o
23、f marketing lies in_.（分数：1.00）A.all understanding of consumer needsB.the efficient movement of goodsC.developing new wants for consumer goodsD.making goods readily available to customers(4).A successful business deal can take place only when_.（分数：1.00）A.the customer is satisfied at the expense of th
24、e companyB.a company makes a big profitC.consumer satisfaction and company profit are given equal importanceD.priority is given to the requirements of the customer(5).The last sentence of the passage suggests that_.（分数：1.00）A.the consumer should be allowed to do things his own wayB.the consumer shou
25、ld be treated like a kingC.the consumer should have the final say in the selling of any productD.the consumer should be advised on what to buy2For several years, scientists have been testing a substance called interferon (干扰素), a potential wonder drug that is proving to be effective in treating a va
26、riety of ailments, in cluding virus infections, bacteria infections, and tumors. To date, the new drug has pro voked no negative reaction of sufficient significance to discourage its use. But in spite of its success, last year only one gram was produced in the entire world.The reason for the scarcit
27、y lies in the structure of interferon. A species of specific pro tein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting whi
28、te blood cells with a virus. For tunately, it is so powerful that the amount given each patient per injection is very small.Unlike antibiotics, interferon does not attack germs directly. Instead, it makes unaf fected cells resistant to infection, and prevents the multiplication of viruses within cel
29、ls.As you might conclude, one of the most dramatic uses of interferon has been in the treatment of cancer. Dr. Hans Strander, research physician at Swedens famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who has und
30、ergone surgical procedures for advanced cancer, half were given interferon. The survival rate over a three-year period was 70 percent among those who were treated with interferon as compared with only 10 to 30 percent among those who have received the conventional treatments.In the United States, a
31、large-scale project supported by the American Cancer Society is now underway. If the experiment is successful, interferon could become one of the grea test medical discoveries of our time.（分数：5.00）(1).In what way does interferon differ from antibiotics?（分数：1.00）A.Interferon has serious side effects,
32、 whereas antibiotics do not.B.Interferon is available in large supply, whereas antibiotics are not.C.Antibiotics are very effective, while interferon is not.D.Antibiotics kill germs by attacking them directly, while interferon does not.(2).What effect does interferon have on infection?（分数：1.00）A.It
33、provokes a negative reaction.B.It keeps healthy cells from becoming infected.C.It causes healthy cells to grow.D.It attacks viruses.(3).Interferon is produced by_.（分数：1.00）A.infecting viruses, bacteria, and tumors with a drugB.infecting proteins with a virusC.infecting white blood cells with a virus
34、D.infecting viruses with proteins(4).Interferon has not been widely used because it is_.（分数：1.00）A.still very dangerousB.not yet available in the United StatesC.difficult to produce in large quantitiesD.not effective for human beings(5).Which of the following is true of the results of Dr. Stranders
35、experiments?（分数：1.00）A.Both interferon and conventional treatments should be used to ensure the survival of the patients.B.At the end of three years, only ten to thirty percent of the patients who had not received interferon died.C.Only the patients who received interferon survived.D.Most of the pat
36、ients who were treated with interferon survive3The biosphere is the name biologists give to the sort of skin on the surface of this planet that is inhabitable by living organisms. Most land creatures occupy only the interface between the atmosphere and the land; birds extend their range for a few hu
37、ndred feet into the atmosphere; burrowing invertebrates (无脊椎动物) such as earthworms may reach a few yards into the soil but rarely penetrate farther unless, it has been recently disturbed by men. Fish cover a wider range, from just beneath the surface of the sea to those depths of greater than a mile
38、 inhabited by specialized creatures. Fungi (真菌) and bacteria are plentiful in the atmosphere to a height of about half a mile, blown there by winds from the lower air. Balloon exploration of the stratosphere (同温层) as long ago as 1936 indicated that moulds and bacteria could be found at heights of se
39、veral miles, recently the USAs National Aeronautics and Space Administration has detected them, in decreasing numbers, at heights up to eighteen miles. They are pretty sparse at such levels, about one for every two thousand cubic feet, compared with 50 to 100 per cubic foot at two to six miles (the
40、usual altitude of jet aircraft), and they are almost certainly in an inactive state. Marine bacteria have been detected at the bottom of the deep Pacific trench, sometimes as deep as seven miles; they are certainly not inactive. Living microbes have also been obtained on land from cores of rock dril
41、led (while prospecting for oil) at depths of as much as 1,200 feet. Thus we can say, disregarding the exploits of astronauts, that the biosphere has a maximum thickness of about twenty-five miles. Active living processes occur only within a compass of about seven miles, in the sea, on land and in th
42、e lower atmosphere, but the majority of living creatures live within a zone of a hundred feet or so. If this planet were sealed down to the size of an orange, the biosphere, at its extreme width, would occupy the thickness of the orange-colored skin, excluding the pith.In this tiny zone of our plane
43、t take place the multitude of chemical and biological activ ities that we call life. The way in which living creatures interact with each other, depend on each other or compete with each other, has fascinated thinkers since the beginning of recorded history. Living things exist in a fine balance whi
44、ch is often taken for granted be cause, from a practical point of view, things could not be otherwise. Yet it is a source of continual amazement to scientists because of its intricacy and delicacy. The balance of na ture is obvious most often when it is disturbed. Yet even here it can seem remarkabl
45、e how quickly it readjusts itself to a new balance after a disturbance. The science of ecologythe study of the interaction of organisms with their environmenthas grown up to deal with the minutiae of the balance of nature.（分数：5.00）(1).According to the passage, the “biosphere“ is the layer on the ear
46、ths surface_.（分数：1.00）A.where the atmosphere meets the seaB.in which birds, fish and animals would dieC.in which plant and animal life can existD.in which earthworms and other invertebrates can live(2).The writer states that fungi and bacteria_.（分数：1.00）A.are only found below the normal altitude of

Con strains become internalized and children begin to weigh from within the validity of their promptings (敦促) . But their tendency to be self-critical, to develop a code of their own, depe
