Just as the trends of the 1980s were difficult to predict, so, too, are the forces that will drive the industry in the 1990s. But by looking at the trends of today, people are able to predict what the industry may look like in the new decade.
Hardware will become a commodity while software and service will account for a greater share of computer companies' revenue, say market watchers. And growth in sales of special systems will come to a halt in the '90s.
As more computer systems are based on such emerging standards as the Unix operating system, customers can pick and choose the best components from different vendors rather than relying on one supplier for complete computer systems. That will accelerate demand for service--rather than products--from vendors. It's the service, the support and the software that add all the value. The move to distributed computers linked by local area networks is increasingly becoming an alternative to centralized computers. A survey of 50 Fortune 1000 companies found that 72 per cent were replacing their minicomputers with personal computer networks. Some trends in the peripherals (外部设备) arena in the next decade are obvious--smaller, quicker, more features. But manufacturers of monitors, printers and disk drives will be looking beyond the computer industry toward future markets that hold vast sales potential.
The automobile industry, for example, holds promise for peripherals vendors. It's very likely in the next five to ten years we'll see vehicles targeted at business executives with printers and fax (传真) machine capabilities built in.
The main idea of the passage is about ______.
A.the trends of the 1990s in computer industry
B.the accelerating demands for software and service
C.computers industry's close link with auto-industry
D.the trends in the peripherals arena in the next decade

听力原文:M: Hello, Prof. Dianna, you wanted to see me? W: Oh, yes, Frank. Thanks for coming. It's about your work as a teaching assistant. I've just read your evaluations, the ones the students filled out toward the end of the semester.
M: Yes...? Well, how were they?
W: Would you like to take a look? Out of a possible score of five, you got a four point eight. That's very high, Frank.
M: Well, what a pleasant surprise.
W: When we see such a high score, we generally try to keep the Teaching Assistant on a little longer and perhaps even ask them to cover more classes. What do you say, Frank? Would you like this?
M: I sure would, but I don't know if I can. Next fall will be my last semester of coursework for my master's and I'll be very busy doing re search on my thesis. Could I have a few days to think about it?
W: Certainly, I wouldn't want you to fall behind in your course-work, but I do think you should consider getting more experience in the class room. You seem to have a real gift.
M: Thanks for your praise, Professor.
W: Let me know by the beginning of next week, will you?
M: Sure thing. I'll drop by again on Monday or Tuesday.

Just as Roman gladiators drank the blood of foes to gain strength, modem Olympians have infused the blood of their own to gain endurance. Blood doping, which tainted the triumphs of some Olympians, has at last been banned.
Blood doping, in short, means withdrawal of one unit of a little more of blood from an athlete's system about four to six weeks before a competition. The blood is then stored in a frozen state while the body replenished the lost blood through natural processes. The extracted blood is unfrozen and then pumped back into the athlete's system just before the competition. This increases the body's hemoglobin count, hereby increasing the capacity for oxygen delivery and raising the level of endurance.
A recent colloquium on the ethics of blood doping, summarized in The Physician and Sports Medicine, cited eases of runners getting blood transfusions so they could run fast enough to qualify for Boston Marathon and of blood doping in dog and horse racing.
Blood doping may be surprisingly common among world-class endurance athletes, especially cyclists and runners. Blood doping is cheating and it is now banned by the International Olympic Committee, but it is still impossible to test, and till sure checks are found, one can only count on the personal ethics of the sportspersons concerned.
Does blood doping really work? Buick et al. and Williams et al. have made some studies in the laboratory. In one study, 11 highly trained male track athletes underwent extensive treadmill testing before and alter phlebotomy with re-infusion of 900mi of antilogous freeze-preserved red cells. The blood doping increased the mean hemoglobin concentration 8% (from 15.1% to 16.3% gnm/100ml) , maximal oxygen consumption 5% , and running time to exhaustion 35%. In another study, 12 experienced male distance runners who received 920ml of antilogous blood had a mean 7% increase in hemoglobin concentration and a mean 45-second improvement in time on a 5-mile treadmill run, compared with results after they received 920m1 saline. In the third study, 9 male college students who received two units antilogous blood had a significant increase in hemoglobin concentration and maximal oxygen consumption on a cycle ergo-meter.
It is reasonable to conclude that blood doping does work when properly performed in the laboratory. But does it work in the field?
The problem in determining if blood doping works in the field is that almost all the reports are anecdotal. Whether it works or not, blood doping as it was done for the U.S. Olympic cyclists is to be condemned. Three of the cyclists developed flu-like symptoms 36 hours after transfusion, and one of them, when asked about blood doping, said, "Yeah, I did it. I got sick and it ruined me for the Olympics." To be sure, some of the cyclists who blood-doped won medals, but so did some who refused blood doping. Likewise, not all Olympians who admitted to blood doping were medal winners: an Italian runner who blood-doped for the marathon said he ran poorly and the national cross-country team alleged to have blood-doped ran poorly. In short, one cannot tell from anecdotal reports whether or not blood doping works in the field.
Which of the following statements best expresses the main idea of the passage?
A.Blood doping does afford athletes a competitive advantage though it is not quite safe.
B.Blood doping works in the laboratory, but there is no evidence to show it works in the field.
C.Blood doping is becoming increasingly common in the world of sports.
D.Athletes who Blood-dope for endurance can perform. better than others.

Saying they can no longer ignore the rising prices of health care, some of the most influential medical groups in the nation are recommending that doctors weigh the costs, not just the effectiveness of treatment, as they make decisions about patient care.
The shift, little noticed outside the medical establishment but already controversial inside it, suggests that doctors are starting to redefine their roles, from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent.
In practical terms, the new guidelines being developed could result in doctors choosing one drug over another for cost reasons or even deciding that a particular treatment-at the end of life, for example-is too expensive. In the extreme, some critics have said that making treatment decisions based on cost is a form. of rationing.
Traditionally, guidelines have heavily influenced the practice of medicine, and the latest ones are expected to make doctors more conscious of the economic consequences of their decisions, even though there’s no obligation to follow them. Medical society guidelines are also used by insurance companies to help determine reimbursement(报销)policies.
Some doctors see a potential conflict in trying to be both providers of patient care and financial overseers.
"There should be forces in society who should be concerned about the budget, but they shouldn’t be functioning simultaneously as doctors," said Dr. Martin Samuels at a Boston hospital. He said doctors risked losing the trust of patients if they told patients, "I’m not going to do what I think is best for you because I think it’s bad for the healthcare budget in Massachusetts."
Doctors can face some grim trade-offs. Studies have shown, for example, that two drugs are about equally effective in treating macular degeneration, an eye disease. But one costs $50 a dose and the other close to $2,000. Medicare could save hundreds of millions of dollars a year if everyone used the cheaper drug. Avastin, instead of the costlier one, Lucentis.
But the Food and Drug Administration has not approved Avastin for use in the eye, and using it rather than the alternative, Lucentis, might carry an additional, although slight, safety risk. Should doctors consider Medicare’s budget in deciding what to use?
"I think ethically(在道德层面上)we are just worried about the patient in front of us and not trying to save money for the insurance industry or society as a whole," said Dr. Donald Jensen.
Still, some analysts say that there’s a role for doctors to play in cost analysis because not many others are doing so. "In some ways," said Dr. Daniel Sulmasy, "it represents a failure of wider society to take up the issue."
57.What do some most influential medical groups recommend doctors do?
A.Reflect on the responsibilities they are supposed to take.
B.Pay more attention to the effectiveness of their treatments.
C.Take costs into account when making treatment decisions.
D.Readjust their practice in view of the cuts in health care.

A.Specific medicines to be used.
B.Professional advancement.
C.Effects of medical treatment.
D.Patients’ trust.
59.What may the new guidelines being developed lead to?
A.The redefining of doctors’ roles.
B.Conflicts between doctors and patients.
C.Overuse of less effective medicines.
D.The prolonging of patients’ suffering.
60.What risk do doctors see in their dual role as patient care providers and financial overseers?
A.They may be involved in a conflict of interest.
B.They may be forced to divide their attention.
C.They may have to use less effective drugs.
D.They may lose the respect of patients.
61.What do some experts say about doctors’ involvement in medical cost analysis?
A.It may add to doctors’ already heavy workloads.
B.It will help to save money for society as a whole.
C.It results from society’s failure to tackle the problem.
D.It raises doctors’ awareness of their social responsibilities.
