单选题It might be supposed that greater efficiency could be achieved if several people worked together to solve a problem than if only one individual works on it. Although groups often may increase the motivation of their members to deal with problems, there are conflicts arising among members of a group. Problem solving needs the presence of an effective leader who not only provides direction, but also permits the orderly, constructive expression of different opinions; much of the leader"s effort may be devoted to resolving differences. Success in problem solving also depends on the distribution of ability within a group. Although groups may reach a greater number of correct solutions, or may require less time to discover an answer, their efficiency is typically lower than that achieved by skilled individuals working alone. In brainstorming, a problem is presented to a group of people who then proceed to offer whatever they can think of. Theoretically these unrestricted suggestions increase the probability that at least some better solutions will appear. Nevertheless, studies show that when individuals work alone under similar conditions, performance tends to proceed more efficiently than it does in groups. Under special circumstances, however, a group may solve problems more effectively than a competent individual does. Group members may contribute different resources to a solution that no individual can achieve alone. Sometimes social demands may require group agreement on a single issue, as in making national economic or military policies under the governments. When only one among several solutions is correct, even if a group requires more time, it has a higher probability of identifying the right one than does an individual alone.

单选题Next to Sir Andrew in the clubroom sits Captain Sentry, a gentleman of great courage, good understanding, but invincible modesty. He is one of those that deserve very well, but are very awkward at putting their talents within the observation of such as should take notice of them. He was some years a captain, and behaved himself with great gallantry in several engagements and at several sieges; but having a small estate of his own, and being next heir to Sir Roger, he has quitted a way of life in which no man can rise suitably to his merit, who is not something of a courtier as well as a soldier. I have heard him often lament that in a profession where merit is placed in so conspicuous a view, impudence should get the better of modesty. When he had talked to this purpose, I never heard him make a sour expression, but frankly confess that he left the world because he was not fit for it. A strict honesty, and an even regular behavior, are in themselves obstacles to him that must press through crowds, who endeavour at the same end with himself, the favor of a commander. He will, however, in his way of talk excuse generals for not disposing according to men's deserts, or inquiring into it; for, says he, that the great man who has a mind to help me, has as many to, break through to come at me, as I have to come at him: therefore he will conclude that the man who would make a figure, especially in a military way, must get over all false modesty, and assist his patron against the importunity of other pretenders, by a proper assurance in his own vindication. He says it is a civil cowardice to be backward in asserting what you ought to expect, as it is a military fear to be slow in attacking when it is your duty. With this candour does the gentleman speak of himself and others. The same frankness runs through all his conversation. The military part of his life has furnished him with many adventures, in the relation of which he is very agreeable to the company; for he is never overbearing, though accustomed to command men in the utmost degree below him; nor ever too obsequious, from a habit of obeying men highly above him.

单选题As the twentieth century began, the importance of formal education in the United States increased. The frontier had mostly disappeared and by 1910 most Americans lived in towns and cities. Industrialization and the bureaucratization of economic life combined with a new emphasis upon credentials and expertise to make schooling increasingly important for economic and social mobility. Increasingly, too, schools were viewed as the most important means of integrating immigrants into American society. The arrival of a great wave of southern and eastern European immigrants at the turn of the century coincided with and contributed to an enormous expansion of formal schooling. By 1920 schooling to age fourteen or beyond was compulsory in most states, and the school year was greatly lengthened. Kindergartens, vacation schools, extracurricular activities, and vocational education and counseling extended the influence of public schools over the lives of students, many of whom in the larger industrial cities were the children of immigrants. Classes for adult immigrants were sponsored by public schools, corporations, unions, churches, settlement houses, and other agencies. Reformers early in the twentieth century suggested that education programs should suit the needs of specific population. Immigrant women were one such population. Schools tried to educate young women so they could occupy productive places in the urban industrial economy, and one place many educators considered appropriate for women was the home.

单选题With human footprints on the moon, radio telescopes listening for messages from alien creatures who may or may not exist, technicians looking for celestial and planetary sources of energy to support our civilization, orbiting telescopes" data hinting at planetary systems around other stars, and political groups trying to figure our how to save humanity from nuclear warfare that would damage life and eliminate on a planet-wide scale, an astronomy book published today enters a world different from the one that greeted books a generation age. Astronomy has broadened to involve our basic circumstances and our mysterious future in the universe. With eclipses and space missions broadcast live, and with NASA, Europe, and Russia planning and building permanent space stations, astronomy offers adventure for all people, an outward exploratory thrust may one day be seen as an alternative to mindless consumerism, ideological bickering, and wars to control dwindling resources on a closed, finite Earth. Today"s astronomy students not only seek an up-to-date summary of astronomical facts: they ask, as people have asked for ages, about our basic relations to the rest of the universe. They may study astronomy partly to seek points of contact between science and other human endeavors, philosophy, history, politics, environmental action, even the arts and religion. Science fiction writers and special effect artists on recent films help today"s students realize that unseen worlds of space are real places--not abstract concepts. Today"s students are citizens of a more real, more vast cosmos than conceptualized by students of a decade age. In designing this edition, the Wadsworh editors and I have tried to respond to these developments. Rather than jumping at the start into murky waters of cosmology, I have begun with the viewpoint of ancient people on Earth and worked outward across the universe. This method of organization automatically (if loosely) reflects the order of humanity"s discoveries about astronomy and provides a unifying theme of increasing distance and scale.

单选题{{B}}Directions:{{/B}} Answer all questions based on the information in the passages below.{{B}}Passage One{{/B}} Let us assume, for the moment, that labor is not prepared to work for a lower money-wage and that a reduction in the existing level of money-wages would lead, through strikes or otherwise, to a withdrawal from the labor market of labor which is now employed. Does it follow from this that the existing level of real wages accurately measures the marginal disutility of labor? Not necessarily. For, although a reduction in the existing money-wage would lead to a withdrawal of labor, it does not follow that a fall in the value of the existing money-wage in terms of wage-goods would do so, if it were due to a rise in the price of the latter. In other words, it may be the case that within a certain range the demand of labor is for a minimum money-wage and not for a minimum real wage. The classical school has tacitly assumed that this would involve no significant change in their theory. But this is not so. For if the supply of labor is not a function of real wages as its sole variable, their argument breaks down entirely and leaves the question of what the actual employment will be quite indeterminate. They do not seem to have realized that. Unless the supply of labor is a function of real wages alone, their supply curve for labor will shift bodily with every movement of prices. Thus their method is tied up with their very special assumptions, and cannot be accepted to deal with the more general case. Now ordinary experience tells us, beyond doubt, that a situation where labor stipulates (within limits) for a money-wage rather than a real wage, so far from being a mere possibility, is the normal case. Whilst workers will usually resist a reduction of money-wages, it is not their practice to withdraw their labor whenever there is a rise in the price of wage-goods. It is sometimes said that it would be illogical for labor to resist a reduction of money-wages but not to resist a reduction of real wages. For reasons given below, this might not be so illogical as it appears at first; and, as we shall see later, fortunately so. But, whether logical or illogical, experience shows that this is how labor in fact behaves. Moreover, the contention that the unemployment which characterizes a depression is due to a refusal by labor to accept a reduction of money-wages is not clearly supported by the facts. It is not very plausible to assert that unemployment in the United States in 1932 was due either to labor obstinately refusing to accept a reduction of money-wages or to its obstinately demanding a real wage beyond what the productivity of the economic machine was capable of furnishing. Wide variations are experienced in the volume of employment without any apparent change either in the minimum real demands of labor or in its productivity. Labor is not more truculent in the depression than in the boom.... far from it. Nor is its physical productivity less. These facts from experience are a prima facie ground for questioning the adequacy of the classical analysis.

单选题When I was walking down the street the other day, I happened to notice a small brown leather wallet lying on the sidewalk. I picked it up and opened it to see if I could find out the owner's name. There was nothing inside it except some change and an old photograph-a picture of a woman and a young gift about twelve years old, who looked like the woman's daughter. I put the photograph back and took the wallet to the police station, where I handed it to the desk sergeant. Before I left, the sergeant took down my name and address in case the owner might want to write and thank me. That evening I went to have dinner with my aunt and uncle. They had also invited a young woman so that there would be four people at the table. Her face was familiar. I was quite sure that we had not met before, but I couldn' t remember where I had seen her. In the course of conversation, however, the young woman happened to mention that she had lost her wallet that afternoon. All at once I realized where I had seen her. She was the young girl in the photograph, although she was now much older. She was very surprised, of course, when I was able to describe her wallet to her. Then I explained that I had recognized her from the photograph I had found in the wallet. My uncle insisted on going to the police station immediately to claim the wallet. As the police sergeant handed it over, he said that it was amazing that I had not only found the wallet, but also the person who had lost it.
