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.
58.What were doctors mainly concerned about in the past？
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.
in a space level (i.e. the complement of a mark) for one element period. This element is called the start bit and has a duration of T seconds. The transmitter then sends the character, l bit at a time, by placing each successive bit on the line for a duration of T seconds, until all bits have been transmitted. Then a single parity bit is calculated by the transmitter and sent after the data bits. Finally, the transmitter sends a stop bit at a mark level (i.e. the same level as the idle state) for one or two bit periods. Now the transmitter may send another character whenever it wishes.
At the receiving end of an asynchronous serial data link, the receiver continually monitors the line looking for a start bit. Once the start bit has been detected, the receiver waits until the end of the start bit and then samples the next N bits at their centers, using a clock generated locally by the receiver. As each incoming bit is sampled, it is used to construct a new character. When the received character has been assembled, its parity is calculated and compared with the received parity bit following the character. If they are not equal, a parity error flag is set to indicate a transmission error.

D.another character
(4).At the receiving end of an asynchronous serial data link, the receiver().
A.does not monitor the start bit
B.waits until the beginning of the start bit
C.samples the start bit at its center

听力原文： Accidents are caused; they don't just happen. The reason may be easy to see: an overloaded tray, a shelf out of reach, a patch of ice on the road. But more often than not there is a chain of events leading up to the misfortune—frustration, tiredness, or just bad temper—that show what the accident really is, a sort of attack on oneself.
Road accidents, for example, happen frequently after a family quarrel, and we all know people who are accident-prone, so often at odds with themselves and the world that they seem to cause accidents for themselves and others.
By definition, an accident is something you cannot predict to avoid, and the idea which used to be current, that the majority of road accidents are caused by a minority of criminally careless drivers, is not supported by insurance statistics. These show that most accidents involve ordinary motorists in a moment of carelessness or thoughtlessness.
It is not always clear, either, what sort of conditions made people more likely to have an accident. For instance, the law requires all factories to take safety precautions and most companies have safety committees to make sure that the regulations are observed, but still, every day in Britain, some fifty thousand men and women are absent from work due to accidents. These accidents are largely the result of human error or misjudgment—noise and fatigue, boredom or worry are possible factors which contribute to this. Doctors who work in factories have found that those who drink too much, usually people, who have a high anxiety level, run three times the normal risk of accidents at work.

A．External conditions.
B．People's internal conditions influenced by physical or mental factors.

听力原文： An airline is an organization which provides aviation services for passengers and cargo. It owns or leases airlines for reasons of mutual benefits. The scale and scope of airline companies range from those with a single airplane carrying mail or cargo, to full service international airlines operating many hundreds of airplanes of various types. Airline services can be categorized as intercontinental, intra-continental, regional or domestic and may be operated as scheduled service or charters. These variations in the types of airline companies, their operating scope, and the routes they serve, make analysis of the airline industry complex. But one thing is certain: The industry is heavily influenced by the market now. In the past 50 years or so, the general trend of ownership bas gone from government-owned or government-supported to independent, for profit companies. This is a result of the government permitting greater freedom. This trend is not yet consistent across all airlines in all regions. The demand for air travel services depends on other things: needs for cargo transportation, business passenger demand, leisure passenger demand, which are all influenced by macroeconomic activity in the market. These trends are highly seasonal, and often depend on day-of-week, or time-of-day. The industry is cyclical. Four or five years of poor performance are followed by five or six years of gradual improvement in performance.

A．The market plays an important role in airline service.
B．It introduces the history of the aviation service.
C．It describes airline companies.
D．It introduces the scale and scope of airline companies.
Reception of communication is achieved by our senses. Sight, hearing and touch play the most important roles. Smell and taste play very limited roles. [30] Examples of visual communication are gesture and imitation. Although both frequently accompany speech, there are systems that rely solely on sight, such as those used by deaf and dumb persons. Another means of communicating visually is by signals of fire, smoke, flags or flashing lights. Feelings may be simply communicated by touch such as by handshaking, although a highly-developed system of handshaking disables blind, deaf, and dumb persons to communicate intelligently. Whistling to someone, clapping hands in a theater, and other forms of communication by sound rely upon the ear as a receiver. The most fully developed form. of auditory communication is, of course, the spoken language.
[31] The means of communication mentioned so far have two features in common: they last only a short time, and the persons involved must be relatively close to each other. Therefore, all are restricted in time and space.
(30)
A．Communication actually takes place when the message is received.
B．There are more means of receiving than of sending communications.
C．Reception of communication involves use of the senses.
D．It is hard to organize by typing the means of sending communication.

To whom it may concern,
As my watch (model: 5M43-0B19, S/N: 6D8256) was clearly in need of repair, I recently took it to the Lexington Repair Center where the defective components in the watches are repaired. To my surprise, my request for the repairs to be billed to your company was declined in spite of the fact that there are still three years remaining in the coverage period. As there are no other authorized service centers in my area, I decided to pay for the repairs myself.
The following are the charges billed by the service center:
Parts:
New mainspring...........$23
New hour hand.............$8
New battery...................$5
Labor.............................$34
Total..............................$70
Showing prices including tax
I have included a copy of the receipt I got for the repairs and a copy of my warranty certificate. Please let me know if you need any additional information.
