According to legend, Aesculapius bore two daughters, Panacea and Hyegeia, who gave rise to dynasties of healers and hygienists. The schism (分离) remains today, in clinical training and in practice; and, because of the imperative nature of medical care and the subtlety of health care, the former has tended to dominate. Preventive medicine has as its primary objective the maintenance and promotion of health. It accomplishes this by controlling or manipulating environmental factors that affect health and disease. For example, in California presently there is serious suffering and substantial economic loss because of the failure to introduce controlled fluoridation (加氟作用) of public water supplies. Additionally, preventive medicine applies prophylactic (预防性的) measures against disease by such actions as immunization and specific nutritional measures. Third, it attempts to motivate people to adopt healthful lifestyles through education.
For the most part, curative medicine has as its primary objective the removal of disease from the patient. It provides diagnostic techniques to identify the presence and nature of the disease process. While these may be applied on a mass basis in an attempt to "screen" out persons with preclinical disease, they are usually applied after the patient appears with a complaint. Second, it applies treatment to the sick patient. In every case, this is, or should be, individualized according to the particular need of each patient. Third, it utilizes rehabilitation methodologies to return the treated patient to the best possible level of functioning.
While it is true that both preventive medicine and curative medicine require cadres of similarly trained personnel such as planners, administrators, and educators, the underlying delivery systems depend on quite distinctive professional personnel. The requirements for curative medicine call for clinically trained individuals who deal with patients on a one-to-one basis and whose training is based primarily on an understanding of the biological, pathological, and psychological processes that determine an individual’s health and disease status. The locus (地方)for this training is the laboratory and clinic. Preventive medicine, on the other hand, calls for a very broad spectrum of professional personnel, few of whom require clinical expertise. Since their actions apply either to environmental situations or to population groups, their training takes place in a different type of laboratory or in a community not necessarily associated with the clinical locus.
The economic differences between preventive medicine and curative medicine have been extensively discussed, perhaps most convincingly by Winslow in the monograph The Cost of Sickness and the Price of Health. Sickness is almost always a negative, nonproductive and harmful state. All resources expended to deal with sickness are therefore fundamentally economically unproductive. Health, on the other hand, has a very high value in our culture. To the extent that healthy members of the population are replaced by sick members, the economy is doubly burdened. Nevertheless, the per capita cost of preventive measures for specific diseases is generally far lower than the per capita cost of curative medicine applied to treatment of the same disease. Prominent examples are dental caries (蛀牙) , poliomyelitis(脊髓灰质炎 ) and phenylketonuria (苯丙酮尿) .
There is an imperative need to provide care for the sick person within a single medical care system, but there is no overriding reason why a linkage is necessary between the two components of a health care system, prevention and treatment. A national health and medical care program composed of semiautonomous systems for personal health care and medical care would have the advantage of clarifying objectives and strategies and of permitting a more equitable division of resources between prevention and cure.
It can be inferred that the author regards a program of controlled fluoridation of public water supplies as ______.

A. an unnecessary government program that wastes economic resources
B. a potentially valuable strategy of preventive medicine
C. a government policy that has relatively little effect on the health of a population
D. an important element of curative medicine

单项选择题
According to Landes, some countries are so poor mainly because [A] they tack work ethic. [B] they lack rationality. [C] they are scientifically backward. [D] they are victimized by colonists.
Although his analysis of Europeans expansion is almost nonexistent, Landes does not argue that Europeans were beneficent bearers of civilization to a benighted world. Rather, he relies on his own commonsense law: "When one group is strong enough to push another around and stands to gain by it, it will do so." In contrast to the new school of world historians, Landes believes that specific cultural values enabled technological advances that in turn made some Europeans strong enough to dominate people in other parts of the world. Europeans therefore proceeded to do so with great viciousness and cruelty. By focusing on their victimization in this process, Landes holds, some postcolonial states have wasted energy that could have been put into productive work and investment. If one could sum up Landes’s advice to these states in one sentence, it might be "Stop whining and get to work." This is particularly important, indeed hopeful, advice, he would argue, because success is not permanent. Advantages are not fixed, gains from trade are unequal, and different societies react differently to market signals. Therefore, not only is there hope for undeveloped countries, but developed countries have little cause to be complacent, because the current situation "will press hard" on them.
The thrust of studies like Landes’s is to identify those distinctive features of European civilization that lie behind Europe’s rise to power and the creation of modernity more generally. Other historians have placed a greater emphasis on such features as liberty, individualism, and Christianity. In a review essay, the art historian Craig Clunas listed some of the less well known linkages that have been proposed between Western culture and modernity, including the propensities to think quantitatively, enjoy pornography, and consume sugar. All such proposals assume the fundamental aptness of the question: What elements of Europeans civilization led to European success It is a short leap from this assumption to outright triumphalism. The paradigmatic book of this school is, of course, The End of History and the Last Man, in which Francis Fukuyama argues that after the collapse of Nazism in the twentieth century, the only remaining model for human organization in the industrial and communications ages is a combination of market economics and limited, pluralist, democratic government.
