单选题While the history of technology can be traced along many lines, one of the most intriguing (引人入胜的) development is that photo technology, the technology of light. From the prehistoric invention of fire to laser beams (激光束)and fiber optics(光纤) , light has continually occupied the minds of inventors. "Their inventions fall into two groups-, the use of light to aid vision and, more interestingly, the use of light for purposes of communication. The use of light for communication is one of the major directions that technology has taken ever since the middle of the nineteenth century. From still (静态的) photography to movies to television ( with a development from black-and-white to color imagery in each) , photo technology has had a great effect upon mass communication and mass education. Unlike the printed word, visual images have more impact because they are more immediate; They copy reality in a way that the printed word cannot. Unlike letter shapes, they are not abstract; unlike words, they require no symbolic interpretation by the mind. Combined with the widespread and uniform spreading of such images, phototechnology affects the thinking of vast audiences and shapes their view of reality. As the number of commercially available television channels grows, the viewer's freedom of choice increases, but so does the burden of that choice.

单选题Warren Buffett, who on May 3rd hosts the folksy extravaganza that is Berkshire Hathaway"s annual shareholders" meeting, is an icon of American capitalism. At 83, he also embodies a striking demographic trend: for highly skilled people to go on working well into what was once thought to be old age. Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well-off and the unskilled poor that is slicing through all age groups. Rapid innovation has raised the incomes of the highly skilled while squeezing those of the unskilled. Those at the top are working longer hours each year than those at the bottom. And the Well-qualified are extending their working lives, compared with those of less-educated people. The consequences, for individuals and society, are profound. But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled. Employment rates are falling among younger unskilled people, whereas older skilled folk are working longer. The divide is most extreme in America, where well-educated baby-boomers are putting off retirement while many less-skilled younger people have dropped out of the workforce. Policy is partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectancy, combined with the replacement of generous defined-benefit pension plans with stingier defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive than their predecessors. Technological change may well reinforce that shift: the skills that complement computers, from management expertise to creativity, do not necessarily decline with age. This trend will benefit not just fortunate oldies but also, in some ways, society as a whole. Government budgets will be in better shape, as high earners pay taxes for longer. Rich countries with lots of well-educated older people will find the burden of ageing easier to bear than other places. At the other end of the social scale, however, things look grim. Nor are all the effects on the economy beneficial. Wealthy old people will accumulate more savings, which will weaken demand. Inequality will increase and a growing share of wealth will eventually be transferred to the next generation via inheritance, entrenching the division between winners and losers still further.

单选题Like fine food, good writing is something we approach with pleasure and enjoy from the first taste to the last. And good writers, like good cooks, do not suddenly appear full-blown. Quite the contrary, just as the cook has to undergo an intensive training, mastering the skills of his trade, the writer must sit at his desk and devote long hours to achieving a style in his writing, whatever its purpose—school work, matters of business, or purely social communication. You may be sure that the more painstaking the effort, the more effective the writing, and the more rewarding. There are still some remote places in the world where you might find a public scribe to do your business or social writing for you, for a fee. There are a few managers who are lucky enough to have the service of that rare kind of secretary who can take care of all sorts of letter writing with no more than a quick note to work from. But for most of us, if there is any writing to be done, we have to do it ourselves. We have to write school papers, business papers or home papers. We are constantly called on to put words to paper. It would be difficult to count the number of such words, messages, letters, and reports put into the mails or delivered by hand, but the daily figure must be enormous. What is more, everyone who writes expects, or at least hopes, that his writing will be read. We want to arouse (引起) and hold the interest of the readers. We want whatever we write to be read, from first word to last, not just thrown into some "letters-to-be-read" file or into a wastepaper basket. This is the reason we bend our efforts toward learning and practicing the skills of interesting, effective writing.
