单选题 In Plato's Utopia, there are three classes: the common people, the soldiers, and the guardians chosen by the legislator. The main problem, as Plato perceives, is to insure that the guardians shall carry out the intention of the legislator. For this purpose the first thing he proposes is education. Education is divided into two parts, music and gymnastics. Each has a wider meaning than at present: "music" means everything that is in the province of the muses, and "gymnastics" means everything concerned with physical training fitness. "Music" is almost as wide as what is now called "culture", and "gymnastics" is somewhat wider than what "athletics" mean in the modern sense. Culture is to be devoted to making men gentlemen, in the sense which, largely owing to Plato, is familiar in England. The Athens of his day was, in one respect, analogous to England in the nineteenth century: there was in each an aristocracy enjoying wealth and social prestige, but having no monopoly of political power; and in each the aristocracy had to secure as much power as it could by means of impressive behavior. In Plato's Utopia, however, the aristocracy rules were unchecked. Gravity, decorum and courage seem to be the qualities mainly to be cultivated in education. There is to be a rigid censorship from very early years over the literature to which the young have access and the music they are allowed to hear. Mothers and nurses are to tell their children only authorized stories. Also, there is a censorship of music. The Lydian and Ionian harmonies are to be forbidden, the first because it expresses sorrow, the second because it is relaxed. Only the Dorian (for courage) and the Phrygian (for temperance) are to be allowed. Permissible rhythms must be simple, and such as are expressive of a courageous and harmonious life. As for gymnastics, the training of the body is to be very austere. No one is to eat fish, or meat cooked otherwise than roasted, and there must be no sauces or candies. People brought up on his regimen, he says, will have no need of doctors. Gymnastics applies to the training of mind as well. Up to a certain age, the young are to see no ugliness or vice. But at a suitable moment, they must be exposed to "enchantments", both in the shape of terrors that must not terrify, and of bad pleasures that must not seduce the will. Only after they have withstood these tests will they be judged fit to be guardians.

单选题1 From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has in creased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of them, women and chil dren on the roads. Man versus the motor-car! It is a never-ending battle which man is los ing. Thousand of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen. It has been rightly said that when a man is sitting behind a steering wheel, his car be comes the extension of his personality. There is no doubt that the motor-car often brings out a man's very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind steering wheels. They swear, they are ill-mannered and aggressive, willful as two-year-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving. The surprising thing is that the society smiles so gently on the motorist and seems to forgive his behavior. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes noth ing more than a statistic, to be conveniently forgotten. It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some of the things that might be done. The driving test should be standardized and made far more diffi cult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person's driving ability. Present drinking and driving laws (where they exist ) should be made much stricter. Maximum and minimum speed lim its should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and perform ance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as too severe if it results in reducing the annual toll of human life. After all, the world is for human beings, not or motor-cars.

单选题A hundred years ago it was assumed and scientifically "proved" by economists that the laws of society make it necessary to have a vast army of poor and jobless people in order to keep the economy going. today, hardly anybody would dare to voice the principle. It is generally accepted that nobody should be excluded from the wealth of the nation, either by the law of nature or by those of society. The opinions are outdated, which were current a hundred years ago, that the poor owed their conditions to their ignorance, lack of responsibility. In all western industrialized countries, a system of insurance has been introduced which guarantees everyone a minimum of subsistence in case of unemployment, sickness and old age. I would go one step further and argue that, even if these conditions are not present, in other words, one can claim this substance minimum without having to have any "reason". I would suggest, however, that it should be limited to a definite period of time, let's say two years, so as to avoid the encouragement of an abnormal attitude which refuses any kind of social obligation. This may sound like a fantastic proposal, but so, I think, our insurance system would have sounded to people a hundred years ago. The main objection to such a scheme would be that if each person were entitled to receive minimum support, people would not work. This assumption rests on the fallacy of the inherent laziness. In human nature, actually, aside from abnormally lazy people, there would be very few who would not want to earn more than the minimum, and who would prefer to do nothing rather than work. However, the suspicions against a system of guaranteed subsistence minimum are not groundless from the standpoint of those who want to use ownership capital for the purpose of forcing others to accept the work conditions they offer. If nobody were forced to accept work in order not to starve, work would be sufficiently interesting and attractive in order to induce one to accept it. Freedom of contract is possible only if both parties are free to accept and reject if; in the present capitalist system this is not the case. But such a system would not only be the beginning of real freedom of contract between employers and employees, its principal advantage would be the improvement of freedom in interpersonal relationships in every sphere of daily life.
