1、华中科技大学考博英语真题答案考试时间 2014年3月22日星期六 下午2:00-5:00 原创作者qq 347952582Since Would War II considerable advances have been made in the area of health-care services. These include better access to health care (particularly for the poor and minorities), improvements in physical plants, and increased numbers of p
2、hysicians and other health personnel. All have played a part in the recent improvement in life expectancy (life expectancy: n.平均寿命(=expectation of life). But there is mounting criticism of the large remaining gaps in access, unbridled cost inflation, the further fragmentation of service, excessive i
3、ndulgence in wasteful high-technology “gadgeteering,” and a breakdown in doctor-patient relationships. In recent years (in recent years: 最近几年中) proposed panaceas and new programs, small and large, have proliferated at a feverish pace and disappointments multiply at almost the same rate. This has led
4、 to an increased pessimism“everything has been tried and nothing works”which sometimes borders on cynicism or even nihilism.It is true that the automatic “pass through” of rapidly spiraling costs (spiraling costs: 螺旋式上升的费用) to government and insurance carriers, which was set in a publicized environm
5、ent of “the richest nation in the world,” produced for a time (for a time: adv.暂时, 一度) a sense of unlimited resources and allowed to develop a mood whereby every practitioner and institution could “do his own thing” without undue concern for the “Medical Commons.” The practice of full-cost reimburse
6、ment encouraged capital investment and now the industry is overcapitalized. Many cities have hundreds of excess hospital beds; hospitals have proliferated a superabundance of high-technology equipment; and structural ostentation and luxury were the order of the day (order of the day: 议程,流行的事物,风尚). I
7、n any given day, one-fourth of all community beds are vacant; expensive equipment is underused or, worse, used unnecessarily. Capital investment brings rapidly rising operating costs (operating costs: 生产费用,营业成本).Yet, in part, this pessimism derives from expecting too much of health care. It must be
8、realized that care is, for most people, a painful experience, often accompanied by fear and unwelcome results. Although there is vast room for improvement, health care will always retain some unpleasantness and frustration. Moreover, the capacities of medical science are limited. Humpty Dumpty (一经损坏
9、无法修复的东西) cannot always be put back together again. Too many physicians are reluctant to admit their limitations to patients; too many patients and families are unwilling to accept such realities. Nor is it true that everything has been tried and nothing works, as shown by the prepaid group practice
10、plans of the Kaiser Foundation and at Puget Sound. In the main (in the main: adv.大体上), however, such undertakings have been drowned by a veritable flood of public and private moneys which have supported and encouraged the continuation of conventional practices and subsidized their shortcomings on a
11、massive, almost unrestricted scale. Except for the most idealistic and dedicated, there were no incentives to seek change or to practice self-restraint or frugality. In this atmosphere, it is not fair to condemn as failures all attempted experiments; it may be more accurate to say many never had a f
12、air trial.1. The author implies that the Kaiser Foundation and Puget Sound plans (lines 47-48) differed from other plans by(A) encouraging capital investment(B) requiring physicians to treat the poor(C) providing incentives for cost control(D) employing only dedicated and idealistic doctors(C)(E) re
13、lying primarily on public funding2. The author mentions all of the following as consequences of full-cost reimbursement EXCEPT(A) rising operating costs(B) underused hospital facilities(C) overcapitalization(D) overreliance on expensive equipment(E)(E) lack of services for minorities3. The tone of t
14、he passage can best be described as(A) light-hearted and amused(B) objective but concerned(C) detached and unconcerned(D) cautious but sincere(B)(E) enthusiastic and enlightened4. According to the author, the “pessimism” mentioned at line 35 is partly attributable to the fact that(A) there has been
15、little real improvement in health-care services(B) expectations about health-care services are sometimes unrealistic(C) large segments of the population find it impossible to get access to health-care services(D) advances in technology have made health care service unaffordable(B)(E) doctors are now
16、 less concerned with patient care5. The author cites the prepaid plans in lines 46-48 as(A) counterexamples to the claim that nothing has worked(B) examples of health-care plans that were over-funded(C) evidence that health-care services are fragmented(D) proof of the theory that no plan has been su
17、ccessful(A)(E) experiments that yielded disappointing results6. It can be inferred that the sentence “Humpty Dumpty cannot always be put back together again” means that(A) the cost of health-care services will not decline(B) some people should not become doctors(C) medical care is not really essenti
18、al to good health(D) illness is often unpleasant and even painful(E)(E) medical science cannot cure every ill7. With which of the following descriptions of the system for the delivery of health-care services would the author most likely agree?(A) It is biased in favor of doctors and against patients
19、.(B) It is highly fragmented and completely ineffective(C) It has not embraced new technology rapidly enough(D) It is generally effective but can be improved(D)(E) It discourages people from seeking medical care8. Which of the following best describes the logical structure of the selection?(A) The t
20、hird paragraph is intended as a refutation of the first and second paragraphs.(B) The second and third paragraphs explain and put into perspective the points made in the first paragraph.(C) The second and third paragraphs explain and put into perspective the points made in the first paragraph.(D) Th
21、e first paragraph describes a problem, and the second and third paragraphs present two horns of a dilemma.(C)(E) The first paragraph describes a problem, the second its causes, and the third a possible solution.9. The authors primary concern is to(A) criticize physicians and health-care administrato
22、rs for investing in technologically advanced equipment(B) examine some problems affecting delivery of health-care services and assess their severity(C) defend the medical community from charges that health-care has not improved since World War II(D) analyze the reasons for the health-care industrys
23、inability to provide quality care to all segments of the population(B)(E) describe the peculiar economic features of the health-care industry that are the causes of spiraling medical costs1. C2. E3. B4. B5. A6. E7. D8. C9. B10. Behavior is one of two general responses available to endothermic (endot
24、hermic: adj.吸热(性)的,动温血的) (warm-blooded) species for the regulation of body temperature, the other being innate (reflexive) mechanisms of heat production and heat loss. Human beings rely primarily on the first to provide a hospitable thermal microclimate (microclimate: n.气小气候(指森林、城市、洞穴等局部地区的气候) for t
25、hemselves, in which the transfer of heat between the body and the environment is accomplished with minimal involvement of innate mechanisms of heat production and loss. Thermoregulatory (thermoregulatory: adj.体温调节的,保持(一定)体温的) behavior anticipates hyperthermia, and the organism adjusts its behavior t
26、o avoid becoming hyperthermic: it removes layers of clothing, it goes for a cool swim, etc. The organism can also respond to changes in the temperature of the body core, as is the case during exercise; but such responses result from the direct stimulation of thermoreceptors distributed widely within
27、 the central nervous system (central nervous system: n. 中枢神经系统), and the ability of these mechanisms to help the organism adjust to gross changes in its environment is limited.Until recently it was assumed that organisms respond to microwave radiation in the same way that they respond to temperature
28、 changes caused by other forms of radiation. After all, the argument runs, microwaves are radiation and heat body tissues. This theory ignores the fact that the stimulus to a behavioral response is normally a temperature change that occurs at the surface of the organism. The thermoreceptors that pro
29、mpt behavioral changes are located within the first millimeter of the skins surface, but the energy of a microwave field (microwave field: 超高频场, 微波场) may be selectively deposited in deep tissues, effectively bypassing these thermoreceptors, particularly if the field is at near-resonant frequencies.
30、The resulting temperature profile (temperature profile: 温度曲线图, 温度轮廓) may well be a kind of reverse thermal gradient in which the deep tissues are warmed more than those of the surface. Since the heat is not conducted outward to the surface to stimulate the appropriate receptors, the organism does no
31、t “appreciate” this stimulation in the same way that it “appreciates” heating and cooling of the skin. In theory (in theory: 理论上), the internal organs of a human being or an animal could be quite literally cooked well-done (well-done: adj.做得好的, 完全煮熟的) before the animal even realizes that the balance
32、 of its thermomicroclimate has been disturbed.Until a few years ago, microwave irradiations at equivalent plane-wave power densities of about 100 mW/cm2 were considered unequivocally to produce “thermal” effects; irradiations within the range of 10 to 100 mW/cm2 might or might not produce “thermal” effects; while effects observed at power densities below 10 mW/cm2 were assumed to be “nonthermal” in nature. Experiments have shown this to be an oversimplification, and a recent report suggests that fields as weak as 1 mW/cm2 can
