单选题The field of medicine has always attracted its share of quacks and charlatans—disreputable women and men with little or no medical knowledge who promise quick cures at cheap prices. The reasons why quackery thrives even in modern times are easy to find. To begin with, pain seems to be a chronic human condition. A person whose body or mind "hurts" will often pay any amount of money for the promise of relief. Second, even the best medical treatment cannot cure all the ills that beset men and women. People who mistrust or dislike the truths that their physicians tell them often turn to more sympathetic ears. Many people lack the training necessary to evaluate medical claims. Given the choice between (a) a reputable physician who says a cure for cancer will be long, expensive and may not work at all, and (b) a salesperson who says that several bottles of a secret formula "snake oil" will cure not only cancer but tuberculosis as well, some individuals will opt for "snake oil" Many "snake oil" remedies are highly laced with alcohol or narcotic drugs. Anyone who drinks them may get so drunk or stoned that they drown their pains in the rising tide of pleasant intoxication. Little wonder that "snake oil" is a popular cure-all for minor aches and hurts! But let there be no misunderstandings. A very few "home remedies" actually work. However, most remedies sold by quacks are not only useless, but often can be harmful as well.

单选题Lawrence Kohlberg Born in 1927, Lawrence Kohlberg spent three years as a junior engineer in the merchant marine before entering college. After those years at sea, he was ready to buckle down and push through the rigorous program at Chicago in record time. He completed the four-year B.A. Degree in 1949 after only two years' work. He clearly demonstrated a great capacity for academic scholarship, and it was natural for him to enroll as a Ph.D. candidate at the same university. He completed his doctorate in 1958; after two years for his undergraduate studies, it took him nine years for the Ph.D. He remarked wryly that it only proved you couldn't accurately predict human behavior in all cases. One of the major reasons for delay was his eventual topic, moral development in children and adolescents. A major portion of his doctoral work was in traditional area of clinical psychology and child development, including a traineeship at the famous Children's Hospital in Boston. A substantial part of his difficulty was that all the time he was learning the traditional theories, including psychoanalytic views, he found in himself a growing skepticism. He began to evolve an alternative set of ideas to explain how children develop moral reasoning. What started as a traditional thesis on the relationship between the superego (the Freudian term for conscience) and moral behavior was transformed into a remarkably original framework for moral development in stages. It is rare for a young Ph.D. candidate to produce truly new insights into human behavior theory. It was uniquely creative for his thesis to force almost a complete revision of moral development theory as well. With the completion of the thesis, finally, after nine years of work, he accepted an assistant professorship at the University of Chicago in 1962. Just six years later he was offered and accepted a full professorship at Harvard University and joined that faculty to form an innovative graduate program in human development. He was also awarded a special five-year Research Career Award by the National Institute of Mental Health to promote his longitudinal study on stages of moral development in adults as well as in children and adolescents. His major significance derives from the possible applications of the theory to promote psychologically healthy human beings. He is presently developing a series of intervention and teaching procedures that show promise of deliberately improving our level of moral judgment and moral maturity. If we are concerned about improving the quality of interpersonal human relationships, his work at present represents the most helpful insights and processes to help us attain that objective.

单选题Of all the areas of learning the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance ; another is the rise of despots like Hitler. Both examples also point up the fact that attitudes stem from experience. In one case the experience was direct and impressive; in the other it was indirect and cumulative. The Nazis were indoctrinated largely by the speeches they heard and the books they read. The classroom teacher in the elementary school is in a strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose word they respect. Another reason it is true is that pupils often delve somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who had previously acquired little knowledge of Mexico, his teacher's method of handling such a unit would greatly affect his attitude toward Mexicans. The media through which the teacher can develop wholesome attitudes are innumerable. Social studies (with special reference to races, creeds and nationalities) , science matters of health and safety, the very atmosphere of the classroom... these are a few of the fertile fields for the inculcation of proper emotional reactions. However. when children come to school with undesirable attitudes, it is unwise for the teacher to attempt to change their feelings by cajoling or scolding them. She can achieve the proper effect by helping them obtain constructive experiences. To illustrate, first grade pupils afraid of policemen will probably alter their attitudes after a classroom chat with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips. Finally, a teacher must constantly evaluate her own attitudes, because her influence can be deleterious if she has personal prejudices. This is especially true in respect to controversial issues and questions on which children should be encouraged to reach their own decisions as a result of objective analysis of all the facts.
