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.

单选题 We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. One might say, "Did Jerry care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend?" Or "Did he envy my luck?" "And Paul — why didn't I pick up that he was friendly just because I had a car?" When we look back, doubts like these can make us feel bad. But when we look back, it's too late. Why are we wrong about our friends or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone says to you, "You're a lucky dog." Is he really on your side? If he says, "You're a lucky guy" or "You're a lucky gal," that's being friendly. But if he says, "You are a lucky dog." There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the dog he put you down a little. What he may be saying is that he doesn't think you deserve your luck. "Just think of all the things you have to be thanking for" is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you have not got a date for Saturday night. How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says square with his tone of voice, his posture, the look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake. Therefore, when you hear someone saying, please try to know what he really means. Don't just listen to what he says with your ears but feel the words he uses with your head. In this way, you may make less mistakes.

单选题 {{B}}My Views on Gambling{{/B}} Most of life is a gamble. Very many of the things we do involve taking some risk in order to achieve a satisfactory result. We undertake a new job with no idea of the more indirect consequences of our action. Marriage is certainly a gamble and so is the bringing into existence of children, who could prove sad liabilities. A journey, a business transaction, even a chance remark may result immediately or ultimately in tragedy. Perpetually we gamble-against life, destiny, chance, the unknown, call the invisible opponent what we will. Human survival and progress indicate that usually we win. So the gambling instinct must be an elemental one. Taking risks to achieve something is a characteristic of all forms of life, including humanity. As soon as man acquired property, the challenge he habitually issued to destiny found an additional expression in a human contest. Early may well have staked his flint axe, his bearskin, his wife, in the hope of adding to his possessions. The acquirement of desirable but nonessential commodities must have increased his scope enormously, while the risk of complete disaster lessened. So long as man was gambling against destiny, the odds were usually in his favor, especially when he used commonsense. But as the methods of gambling multiplied, the chances of success decreased. A wager against one person offered on average even chances and no third party profited by the transaction. But as soon as commercialized city life developed, mass gambling become common. Thousands of people now compete for large prizes, but with only minute chances of success, while the organizers of gambling concerns enjoy big profits with, in some cases, no risk at all. Few clients of the betting shops, football pools, state lotteries, bingo sessions, even charity raffles, realize fully the flimsiness of their chances and the fact that without fantastic luck they are certain to lose rather than gain. Little irreparable harm results for the normal individual. That big business profits from the satisfaction of a human instinct is a common enough phenomenon. The average wage-earner, who leads a colorless existence, devotes a small percentage of his earnings to keeping alive with extraordinary constancy the dream of achieving some magic change in his life. Gambling is in most cases a non-toxic drug against boredom and apathy and may well preserve good temper, patience and optimism in dreary circumstances. A sudden windfall may unbalance a weaker, less intelligent person and even ruin his life. And the line of something for nothing as an ideal evokes criticism from the more rigidly upright representatives of the community. But few of us have the right to condemn as few of us can say we never gamble-even it is only investing a few pence a week in the firm's football sweep or the church bazaar "lucky dip." Trouble develops, however, when any human instinct or appetite becomes overdeveloped. Moderate drinking produces few harmful effects but drunkenness and alcoholism can have terrible consequences. With an unlucky combination of temperament and circumstances, gambling can only become an obsession, almost a form of insanity, resulting in the loss not only of a man's property but of his self-respect and his conscience. Far worse are the sufferings of his dependants, deprived of material comfort and condemned to watching his deterioration and hopelessness. They share none of his feverish excitement or the exhilaration of his rare success. The fact that he does not wish to be cured makes psychological treatment of the gambling addict almost impossible. He will use any means, including stealing, to enable him to carry on. It might be possible to pay what salary he can earn to his wife for the family maintenance but this is clearly no solution. Nothing-education, home environment, other interest, wise discouragement-is likely to restrain the obsessed gambler and even when it is he alone who suffers the consequences, his disease is a cruel one, resulting in a wasted, unhappy life. Even in the case of the more physically harmful of human indulgences, repressive legislation often merely increases the damage by causing more vicious activities designed to perpetuate the indulgence in secret. On the whole, though negative, gambling is no vice within reasonable limits. It would still exist in an ideal society. The most we can hope for is control over exaggerated profits resulting from its business exploitation, far more attention and research devoted to the unhappy gambling addict and the type of education which will encourage an interest in so many other constructive activities that gambling itself will lose its fascination as an opiate to a dreary existence. It could be regarded as an occasional mildly exciting game, never to be taken very seriously.
