单选题October 20, 2006 Mr. Joe Fernandez 1385 Midland Ave Detroit, Michigan Dear Mr. Fernandez, As the president, I am proud to announce that this Friday marks the 30th anniversary of our long an successful running country club. This, of course, calls for a night of celebration. And for this reason, we have reserved the Grand Hall at the Falcon Hotel this Friday at 7:00 p.m. for a night of fine dining an dancing. On this special evening, the newest members of our club will get an opportunity to listen to the thoughts of our older members and exchange ideas in an informal atmosphere. The newest members, who will be carrying on our tradition, should hear what the older members have to say. Further, the food will be superb. I have a chance to dine at the hotel several times in the past in other functions, and it was the food that convinced me to hold our event there. I am quite certain that all of our members will share my feeling. Anyhow, I am looking forward to this Friday when all of our members can let loose and have some fun. Therefor, this is a letter to officially invite you and your spouse or significant other to join us on this memorable evening. Please let us know if you can't attend. Yours sincerely, Jeff Connelly

单选题From: David Johnson To: Eric Anderson Hello, Eric. Thanks for your email. First, I'd like to say how pleased I was to hear that your company accepted our bid to design your new ad campaign. We will be using a subcontractor to handle all of the printing for this campaign, including pamphlets and signs. In the past, we have used a company called Quality Press. It is a subsidiary of Printco, and is quite reliable. I will send you a list of their estimated costs, along with a spreadsheet outlining the revision to our proposed schedule. Also, I have assigned one of our staff members to assemble a task for that will be in charge of consumer research for this project. Her name is Karen Lopez and she's a specialist in market trends. She will be mailing you a packet containing a summary of our preliminary market research later today. David Johnson

单选题 I was blind, but I was ashamed of it if it was known. I refused to use a white stick and hated asking for help. After all, I was a teenager girl, and I couldn't bear people to look at me and think I was not like them. I must have been a terrible danger on the roads, coming across me wandering through the traffic, motorists probably would have to step rapidly on their brakes. Apart from that, there were all sorts of disasters that used to occur on the way to and from work. One evening, I got off the bus about halfway home where I had to change buses, and as usual I ran into something. "I'm awfully sorry," I said and stepped forward only to run into it again. When it happened a third time, I realized I had been apologizing to a lamppost. This was just one of the stupid things that constantly happened to me. So I carried on and found the bus stop, which was a request stop, where the bus wouldn't stop unless passengers wanted to get on or off. No one else was there and I had to try to guess if the bus had arrived. Generally in this situation, because I hated showing I was blind by asking for help, I tried to guess at the sound. Sometimes I would stop a big lorry and stand there feeling stupid as it drew away. In the end, I usually managed to swallow my pride and ask someone at the stop for help. But on this particular evening no one joined me at the stop; It seemed that everyone had suddenly decided not to travel by bus. Of course I heard plenty of buses pass, or I thought I did. But because I had given up stopping them for fear of making a fool of myself, I let them all go by. I stood there alone for half an hour without stopping one. Then I gave up. I decided to walk on to the next stop.

单选题To paraphrase 18th-century statesman Edmund Burke, "all that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from or is animals—no meat, no fur, no medicines, Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don"t worry, scientists will find some way of using computers." Such well-meaning people just don"t understand. Scientists must communicate their message to the public in a compassionate, understandable way—in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother"s hip replacement, a father"s bypass operation, a baby"s vaccinations, and even a pet"s shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.

单选题The health-care economy is replete with unusual and even unique economic relationships．One of the least understood involves the peculiar roles of producer or“provider”and purchaser or“consumer”in the typical doctor-patient relationship，in most sectors of the economy，it is theseller who attempts to attract a potential buyer with various inducements of price，quality，andutility，and it is the buyer who makes the decision．Where circumstances permit the buyer nochoice because there is effectively only one seller and the product is relatively essential，government usually asserts monopoly and places the industry under price and other regulations．Neither of these conditions prevails in most of the health-care industry．In the health-care industry，the doctor-patient relationship is the mirror image of the ordinaryrelationship between producer and consumer．Once an individual has chosen to see a physician andeven then there may be no real choice--it is the physician who usually makes all significantpurchasing decisions：whether the patient should return“next Wednesday”．whether X-rays areneeded，whether drugs should be prescribed，et@C@It is a rare and sophisticated patient who willchallenge such professional decisions or raise in advance questions about price，especially when theailment is regarded as serious．This is particularly significant in relation to hospital care．The physician must certify the needfor hospitalization，determine what procedures will be performed，and announce when the patientmay be discharge@D@The patient may be consulted about some of these decisions，but in the main itis the doctor’S judgments that are final．Little wonder then that in the systems of the hospital it isthe physician who is the real“consumer”．As a consequence，the medical staff represents the“power center”in hospital policy and decision-making，not the administration．Although usually there are in this situation four identifiable participants-the physician，thehospital，the patient，and the payer(generally an insurance carrier or government)—the physicianmakes the essential decisions for all of them．The hospital becomes an extension of the physician；the payer generally meets most of the real bills generated by the physician／hospital；and for themost part the patient plays a passive role．In routine or minor illnesses，or just plain worries，thepatient’s options are，of course，much greater with respect to use and price．In illnesses that are ofsome significance，however，such choices tend to evaporate，and it is for these illnesses that thebulk of the health-care dollar is spent．We estimate that about 75-80 percent of health-careexpenditures are determined by physicians，not patients．For this reason，economy measuresdirected at patients or the general public are relatively ineffective．

单选题While it is generally agreed that the power of large companies extends beyond the economic sphere, this influence is difficult to measure in any objective way. The processes of business entail at least some effort to ensure the sympathetic enactment and enforcement of legislation, since costs and earnings are affected by tax rates and government regulations. Companies and business groups send agents to local and national capitals and use such vehicles as advertising to enlist support for policies that they favor. Although, in many countries, companies may not legally contribute directly to candidates running for public office, their executives and stockholders may do so as individuals. Companies may, however, make payments to influence peddlers and contribute to committees working to pass or defeat legislative proposals. In practical terms, many lawmakers look upon companies as part of their constituency, although, if their districts depend on local plants, these lawmakers may be concerned more with preserving jobs than with protecting company profits. In any case, limited-liability companies are central institutions in society; it would be unrealistic to expect them to remain aloof from the political process that affects their operations, performance, and principles. The decisions made by company managements have ramifications throughout society. In effect, companies can decide which parts of the country or even which parts of the world will prosper and which will decline by choosing where to locate their plants and other installations. The giant companies not only decide what to produce but also help to instill in their customers a desire for the amenities that the companies make available. To the extent that large firms provide employment, their personnel requirements determine the curricula of schools and universities. For these reasons, individuals' aspirations and dissatisfactions are likely to be influenced by large companies. This does not mean that large business firms can influence the public in any way they choose; it is simply that they are the only institutions available to perform certain functions. Automobiles, typewriters, frozen food, and electric toasters must come from company auspices if they are to be provided at all. Understanding this dependence as a given, companies tend to create an environment congenial to the conduct of their business.
