| 第7题：Whether work should be placed among the causes of happiness or among the causes of unhappiness may perhaps be regarded as a doubtful question. There is certainly much work which is exceedingly weary and an excess of work is always very painful. I think, however, that, provided work is not excessive in amount, even the dullest work is to most people less painful than idleness. There are in work all grades, from mere relief of tedium up to the profoundest delights, according to the nature of the work and the abilities of the worker. Most of the work that most people have to do is not in itself interesting, but even such work has certain great advantages. To begin with, it fills a good many hours of the day without the need of deciding what one shall do. Most people, when they are left free to fill their own time according to their own choice, are at a loss to think of anything sufficiently pleasant to be worth doing.And whatever they decide, they are troubled by the feeling that something else would have been pleasanter. To be able to fill leisure intelligently is the last product of civilization, and at present very few people have reached this level. Moreover the exercise of choice is in itself tiresome.Except to people with unusual initiative it is positively agreeable to be told what to do at each hour of the day, provided the orders are not too unpleasant. Most of the idle rich suffer unspeakable boredom as the price of their freedom from toil.At times they may find relief by hunting big game inAfrica, or by flying round the world, but the number of such sensations is limited, especially after youth is past,Accordingly the more intelligent rich men work nearly as hard as if they were poor, while rich women for the most part keep themselves busy with innumerable trifles of those earth-shaking importance they are firmly persuadeD、 Work therefore is desirable, first and foremost, as a preventive of boredom, for the boredom that a man feels when he is doing necessary though uninteresting work is as nothing in comparison with the boredom that he feels when he has nothing to do with his days. With this advantage of work another is associated, namely that it makes holidays much more delicious when they come. Provided a man does not have to work so hard as to impair his vigor, he is likely to find far more zest in his free time than an idle man could possibly finD、 The second advantage of most paid work and of some unpaid work is that it gives chances of success and opportunities for ambition. In most work success is measured by income, and while our capitalistic society continues, this is inevitable. It is only where the best work is concerned that this measure ceases to be the natural one to apply. The desire than men feel to increase their income is quite as much a desire for success as for the extra comforts that a higher income can acquire. However dull work may be, it becomes bearable if it is a means of building up a reputation, whether in the world at large or only in one’s own circle. In the author’s opinion, what is the last product of civilization A、To make wise use of leisure. B．To be free from hard work. C．To keep oneself busy with trifles. D．To work to some extent. |

| 第13题：It is no longer just dirty blue-collar jobs in manufacturing that are being sucked offshore but also white-collar service jobs, which used to be considered safe from foreign competition. Telecoms charges have tumbled, allowing workers in far-flung locations to be connected cheaply to customers in the developed worlD、This has made it possible to offshore services that were once non-tradable. Morgan Stanley’s Mr. Roach has been drawing attention to the fact that the "global labour arbitrage" is moving rapidly to the better kinds of jobs. It is no longer just basic data processing and call centres that are being outsourced to low-wage countries, but also software programming, medical diagnostics, engineering design, law, accounting, finance and business consulting. These can now be delivered electronically from anywhere in the world, exposing skilled white-collar workers to greater competition. The standard retort to such arguments is that outsourcing abroad is too small to matter much. So far fewer than lmAmerican service-sector jobs have been lost to off-shoring. Forrester Research forecasts that by 2015 a total of 3.4m jobs in services will have moved abroad, but that is tiny compared with the 30m jobs destroyed and created inAmerica every year. The trouble is that such studies allow only for the sorts of jobs that are already being off-shored, when in reality the proportion of jobs that can be moved will rise as IT advances and education improves in emerging economies. AlanBlinder, an economist at Princeton University, believes that most economists are underestimating the disruptive effects of off-shoring, and that in future two to three times as many service jobs will be susceptible to off-shoring as in manufacturing. This would imply that at least 30% of all jobs might be at risk. In practice the number of jobs off-shored toChina or India is likely to remain fairly modest.Even so, the mere threat that they could be shifted will depress wages. Moreover, says Mr.Blinder, education offers no protection. Highly skilled accountants, radiologists or computer programmers now have to compete with electronically delivered competition from abroad, whereas humble taxi drivers, janitors and crane operators remain safe from off-shoring. This may help to explain why the real median wage ofAmerican graduates has fallen by 6% since 9000, a bigger decline than in average wages. In the 1980s and early 1990s, the pay gap between low-paid, low-skilled workers and high-paid, high-skilled Workers widened significantly.But since then, according to a study byDavidAutor, Lawrence Katz and Melissa Kearney, inAmerica,Britain and Germany workers at the bottom as well as at the top have done better than those in the middle-income group. Office cleaning cannot be done by workers in IndiA、It is the easily standardised skilled jobs in the middle, such as accounting, that are now being squeezed hardest.A、study byBradford Jensen and Lori Kletzer, at the Institute for InternationalEconomics in WashingtonD、 C、, confirms that workers in tradable services that are exposed to foreign competition tend to be more skilled than workers in non-tradable services and tradable manufacturing industries. According to the text, Forrester Research Prediction might be different if ______. [A] outsourcing abroad is large enough to matter much [B] the proportion of jobs that can be moved will rise [C] more comprehensive factors are taken into account [D] education improvement in emerging economies plays a role |
