问题     The "paperless office" has earned a proud place on lists of technological promises that did not come to pass. Surely, though, the more modest goal of the carbon-paperless office is within the reach of mankind? Carbon paper allows two copies of a document to be made at once. Nowadays, a couple of keystrokes can do the same thing with a lot less fuss.
    Yet carbon paper persists. Forms still need to be filled out in a way that produces copies. This should not come as a surprise. Innovation tends to create new niches(合适的职业), rather than refill those that already exist. So technologies may become marginal, but they rarely go extinct. And today the little niches in which old technologies take refuge are ever more viable and accessible, thanks to the Internet and the fact that production no longer needs to be so mass; making small numbers of obscure items is growing easier.
    On top of that, a widespread technostalgia(技术怀旧)seeks to preserve all the ways people have ever done anything, simply because they are kind of neat. As a result technologies from all the way back to the stone age persist and even flourish in the modern world. According to What Technology Wants, a book by Kevin Kelly, one of the founders of Wired magazine, America’s flintknappers(燧石工)produce over a million new arrow and spear heads every year. One of the things technology wants, it seems, is to survive.
    Carbon paper, to the extent that it may have a desire for self-preservation, may also take comfort in the fact that, for all that this is a digital age, many similar products are hanging on, and even making comebacks. Indeed, digital technologies may prove to be more transient than their predecessors. They are based on the idea that the medium on which a file’s constituent 0s and 1s are stored doesn’t matter, and on Alan Turing’s insight that any computer can mimic any other, given memory enough and time. This suggests that new digital technologies should be able to wipe out their predecessors completely. And early digital technologies do seem to be vanishing. The music cassette is enjoying a little renaissance, its very faithlessness apparently part of its charm; but digital audio tape seems doomed.
    So revolutionary digital technologies may yet discard older ones to the dustbin. Perhaps this will be the case with a remarkable breakthrough in molecular(分子的)technology that could, in principle, store all the data ever recorded in a device that could fit in the back of a van. In this instance, it would not be a matter of the new extinguishing the old. Though it may never have been used for MP3s and PDFs before, DNA has been storing data for over three billion years. And it shows no sign of going extinct.
What can be inferred about digital technologies?
选项 A、Digital audio tape will be vanished because of its accuracy.
B、Digital technologies have been proved to outlive the old technologies.
C、Early digital technologies will never go extinct.
D、The future of digital technologies will be used for DNA research.
答案A
解析 推理判断题。本题考查对数字技术的理解。由定位句“音乐磁带正悄然成为复兴的潮流，失真特质似乎正是其魅力的一部分；但数字录音带似乎难逃消亡的厄运”可知．数字录音带似乎难逃消亡的厄运是由于其保真性，故答案为A)。该段第二句指出“事实上，数字技术的存在时间可能比之前的技术更加短暂”，而非存活得更久，故排除B)“数字技术要比旧的技术存在得更久”；C)“早期的数字技术永远都不会消亡”与该段倒数第二句“早期的数字技术似乎的确正在消失”不符，故排除；D)“数字技术在未来会被应用于DNA研究”原文并未提及，故排除。
