单选题{{B}}Passage 6{{/B}} What do the extraordinarily successful companies have in common? To find out, we looked for operations. We know that correlations are not always reliable; nevertheless, in the 27 survivors, our group saw four shared personality traits that could explain their longevity (长寿). {{U}}Conservatism in financing.{{/U}} The companies did not risk their capital gratuitously (无缘无故地). They understood the meaning of money in an old-fashioned way; they knew the usefulness of spare cash in the kitty. Money in hand allowed them to snap up (抓住) options when their competitors could not. They did not have to convince third-party financiers of the attractiveness of opportunities they wanted to pursue. Money in the kitty allowed them to govern their growth and evolution. {{U}}Sensitivity to the world around them.{{/U}} Whether they had built their fortunes on knowledge or on natural resources, the living companies in our study were able to adapt themselves to changes in the world around them. As wars, depressions, technologies, and politics surged and ebbed (潮起潮落), they always seemed to excel at keeping their feelers out, staying attuned to whatever was going on. For information, they sometimes relied on packets carried over vast distances by portage and ship, yet they managed to react in a timely fashion to whatever news they received. They were good at learning and adapting. {{U}}Awareness of their identity.{{/U}} No matter how broadly diversified the companies were, their employees all felt like parts of a whole. Lord Cole, chairman of Unilever in the 1960s, for example, saw the company as a fleet of ships. Each ship was independent, but the whole fleet was greater than the sum of its parts. The feeling of belonging to an organization and identifying with its achievements is often dismissed softly, but case histories repeatedly show that a sense of community is essential for long-term survival. Managers in the living companies we studied were chosen mostly from within, and all considered themselves to be stewards of a longstanding enterprise. Their top priority was keeping the institution at least as healthy as it had been when they took over. {{U}}Tolerance of new ideas.{{/U}} The long-lived companies in our study tolerated activities in the margin: experiments and eccentricities that stretched their understanding. They recognized that new businesses may be entirely unrelated to existing businesses and that the act of starting a business need to be centrally controlled. W. R. Grace, from its very beginning, encouraged autonomous experimentation. The company was founded in 1854 by an Irish immigrant in Peru and traded in guano, a natural fertilizer, before it moved into sugar and tin. Eventually, the company established Pan American Airways. Today it is primarily a chemical company, although it is also the leading provider of kidney dialysis (透析) services in the United States. By definition, a company that survives for more than a century exists in a world it cannot hope to control. Multinational companies are similar to the long-surviving companies of our study in that way. The world of a multinational is very large and stretches across many cultures. That world is inherently less stable and more difficult to influence than a confined national habitat. Multinationals must be willing to change in order to succeed. These four traits form the essential character of companies that have functioned successfully for hundreds of years. Given this basic personality, what priorities do the managers of living companies set for themselves and their employees?

单选题{{B}}Passage 2{{/B}} As one works with color in a practical or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile changeable thing depending to a large extent on the relationship of the color to other colors seen simultaneously. It is not fixed in its relation to the direct stimulus which creates it. On the other hand, the properties of surfaces that give rise to color do not seem to change greatly under a wide variety of illumination colors, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be due in large part to the mechanism of color adaptation mentioned earlier. When the eye is fixed on a colored area, there is an immediate readjustment of the sensitivity of the eye to color in and around the area viewed. This readjustment does not immediately affect the color seen but usually does affect the next area to which the gaze is shifted. The longer the time of viewing, the higher the intensity, and the larger the area, the greater the effect will be in terms of its persistence in the succeeding viewing situation. As indicated by the work of Wright and Shouted, it appears that, at least for a first approximation, full adaptation takes place over a very brief time if the adapting source is moderately bright and the eye has been in relative darkness just previously. As the stimulus is allowed to act, however, the effect becomes more persistent in the sense that it takes the eye longer to regain its sensitivity to lower intensities. The net result is that, if the eye is so exposed and then the gaze is transferred to an area of lower intensity, the loss of sensitivity produced by the first area will still be present and appear as an "afterimage" superimposed on the second. The effect not only is present over the actual area causing the "local adaptation" but also spreads with decreasing strength to adjoining areas of the eye to produce "lateral adaptation." Also, because of the persistence of the effect if the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors, the adaptation will tend to become uniform over the whole eye.

单选题The other problem that arises from the employment of women is that of the working wife. It has two aspects: that of the wife who is more of a success than her husband and that of the wife who must rely heavily on her husband for help with domestic tasks. There are various ways in which the impact of the first difficulty can be reduced. Provided that husband and wife are not in the same or directly comparable lines of work, the harsh fact of her greater success can be obscured by a genial conspiracy to reject a purely monetary measure of achievement as intolerably crude. Where there are ranks, it is best if the couple work in different fields so that the husband can find some special reason for the superiority of the lowest figure in his to the most elevated in his wife"s. A problem that affects a much larger number of working wives is the need to reallocate domestic tasks if there are children. In The Road to Wigan Pier George Orwell wrote of the unemployed of the Lancashire coalfields. "Practically never.., in a working- class home, will you see the man doing a stroke of the housework. Unemployment has not changed this convention, which on the face of it seems a little unfair. The man is idle from morning to night but the woman is as busy as ever—more so, indeed, because she has to manage with less money. Yet so far as my experience goes the women do not protest. They feel that a man would lose his manhood if, merely because he was out of work, he developed in a "Mary Ann". " It is over the care of young children that this re-allocation of duties becomes really significant. For this, unlike the cooking of fish fingers or the making of beds, is an inescapably time-consuming occupation, and time is what the fully employed wife has no more to spare of than her husband. The male initiative in courtship is a pretty indiscriminate affair, something that is tried on with any remotely plausible woman who comes within range and, of course, with all degrees of tentativeness. What decides the issue of whether a genuine courtship is going to get under way is the woman"s response. If she shows interest the engines of persuasion are set in movement. The truth is that in courtship society gives women the real power while pretending to give it to men. What does seem clear is that the more men and women are together, at work and away from it, the more the comprehensive amorousness of men towards women will have to go, despite all its past evolutionary services. For it is this that makes inferiority at work abrasive and, more indirectly, makes domestic work seem unmanly, if there is to be an equalizing redistribution of economic and domestic tasks between men and women there must be a compensating redistribution of the erotic initiative. If women will no longer let us beat them, they must allow us to join them as the blushing recipients of flowers and chocolates.

单选题Violin prodigies, I learned, have come in distinct waves from distinct regions. Most of the great performers in the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe, I asked Isaac Stern, one of the world's greatest violinists the reason for this phenomenon. "It is very clear," he told me, "They were all Jews (犹太人) and Jews at the time were severely oppressed and ill-treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage." As a result, every Jewish parent's dream was to have a child in the music school because it was a passport to the West. Another element in the emergence of prodigies, I found, is a society that values excellence in a certain field to nurture (培育) talent. Nowadays, the most nurturing societies seem to be in the Far East. "In Japan, a most competitive society, with stronger discipline than ours." says Isaac Stem, children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War Ⅱ, that music not only became part of their daily lives, but it became a discipline as well. The Koreans and Chinese as we know, are just as highly motivated as the Japanese. That's a good thing, because even prodigies must work hard. Next to hard work, biological inheritance plays an important role in the making of a prodigy. J. S. Bach, for example, was the top of several generations of musicians, and four of his sons had significant careers in music.
