单选题These days we hear a lot of nonsense about the "great classless society". The idea that the twentieth century is the age of the common man has become one of the great cliches of our time. The same old arguments are put forward in evidence. Here are some of them: monarchy as a system of government has been completely discredited. The monarchies that survive have been deprived of all political power. Inherited wealth has been savagely reduced by taxation and, in time, the great fortunes will disappear altogether. In a number of countries the victory has been complete. The people rule; the great millennium has become a political reality. But has it? Close examination doesn't bear out the claim. It is a fallacy to suppose that all men are equal and that society will be leveled out if you provide everybody with the same educational opportunities. It is debatable whether you can ever provide everyone with the same educational opportunities, but that is another question. The fact is that nature dispenses brains and ability with a total disregard for the principle of equality. The old rules of the jungle, "survival of the fittest" , and "might is right" are still with us. The spread of education has destroyed the old class system and created a new one. Rewards are based on merit. For "aristocracy" read " meritocracy" ; in other respects, society remains unaltered: the class system is rigidly maintained. Genuine ability, animal cunning, skill, the knack of seizing opportunities, all bring material rewards. And what is the first thing people do when they become rich? They use their wealth to secure the best possible opportunities for their children, to give them " a good start in life". For all the lip service we pay to the idea of equality, we do not consider this wrong in the western world. Private schools which offer unfair advantages over state schools are not banned because one of the principles in a democracy is that people should be free to choose how they will educate their children. In this way, the new meritocracy can perpetuate itself to a certain extent; an able child from a wealthy home can succeed far more rapidly than his poorer counterpart. Wealth is also used indiscriminately to further political ends. It would be almost impossible to become the leader of a democracy without massive financial backing. Money is as powerful a weapon as ever it was. In societies wholly dedicated to the principle of social equality, privileged private education is forbidden. But even here people are rewarded according to their abilities. In fact, so great is the need for skilled workers that the least able may be neglected. Bright children are carefully and expensively trained to become future rulers. In the end, all political ideologies boil down to the same thing: class divisions persist whether you are ruled by a feudal king or an educated peasant.

单选题{{B}}Passage Five{{/B}} Psychologists take opposing views of how external rewards, from warm praise to cold cash, affect motivation and creativity. Behaviorists, who study the relation between actions and their consequences, argue that rewards can improve performance at work and school. Cognitive researchers, who study; various aspects of mental life, maintain that rewards often destroy creativity by encouraging dependence on approval and gifts from others. The latter view has gained many supporters, especially among educators. But the careful use of small monetary rewards sparks creativity in grade-school children, suggesting that properly presented inducements indeed aid inventiveness, according to a study in the June Journal of Personality and Social Psychology. "If kids know they're working for a reward and can focus on a relatively challenging task, they show the most creativity," says Robert Eisenberger of the University of Delaware in Newark, "But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards." A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Eisenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore failing grades. In earlier grades, the use of so-called token economies, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims.

单选题Tourism develops culture. It broadens the thinking of the traveler and leads to culture 1 between the hosts and guests from far-off places. This can benefit the locals, since tourists bring culture 2 them. Tourism may help to preserve indigenous customs, 3 traditional shows, parades, celebrations and festivals are put on for tourists.

On the other hand, tourism often contributes to the disappearance of local traditions and folklore. Churches, temples and similar places of worship are 6 as tourist attractions.
