    It may be the last book you’ll ever buy. And certainly, from a practical standpoint, it will be the only book you’ll ever need. No, It’s not the Bible or some New Age tome promising enlightenment—although it would let you carry around both texts simultaneously. It’s an electronic book—a single volume that could contain a library of information or, if your tastes run toward what’s current, every title on today’s best-seller list. And when you’re done with those, you could refill it with new titles.
    Why an electronic book? Computers can store a ton of data and their laptop companions make all that information portable. True enough. But laptops and similar portable information devices require a lot of power—and heavy batteries—to keep their LCD screens operating. And LCDs are not easy to read in the bright light of the sun.
    The fact is, when it comes to portability, easy viewing, and low power requirements, it’s hard to beat plain old paper.
    So let’s make the ink electronic.
    That’s the deceptively simple premise behind a project currently coming to fruition at the Massachusetts Institute of Technology. Some hurdles mostly having to do with large-scale manufacturing—remain, so it will be a few years before you see an electronic book for sale in stores. But the basic technology already exists, developed at the Institute’s Media Lab by a team led by physicist Joe Jacobson.
    Simply put, each paper page in an electronic book is coated with millions of microscopic particles encased in tiny capsules. Each of these microcapsules can respond independently to an electrical charge: Particles within the capsule moving to the rear appear dark while those moving toward the front look white. The direction in which the particles move depends upon whether a negative (dark) or positive (white) charge is applied. Each microcapsule is about 40 microns in size (that’s a little less than half the thickness of a human hair ).
    The number of microcapsules used on a given page is enormous. For instance, about 1,000 microcapsules might be used to create the letter “A” on this page. “The smaller the size of the letter the more micro-capsules you use,” says Jacobson, “thereby improving resolution.” The target is to have a “paper display” with a resolution higher than that offered by today’s computer screens. More than static letters is at stake. Theoretically, the microcapsules could be programmed to “flip” rapidly between dark and white states, providing, for example, a sense of motion in a diagram showing how a car works.
    Thanks to electronic ink, the book essentially typesets itself, receiving instructions for each page via electronics housed in the spine. From a power standpoint, this process makes the electronic book very efficient. Unlike an LCD screen, which uses power all the time, energy is no longer needed to view the electronic book’s pages once they are typeset. Only a small battery would be required, as opposed to the large ones needed to power laptop computers and their LCDs.
    Convenience, though, is still the main attraction—and that means more than simple portability. Because the information is in electronic form, it can be easily manipulated. You could, for instance, make the type larger for easier reading. Or you could make notes in the margin with a stylus, your observations being stored on tiny, removable flash-memory cards in the spine.
    It’s likely that electronic books will come pre-loaded with a selection of titles. New titles could be made available through flash-memory cards, for example. Jacobson, though, thinks the Internet will be the delivery method: of choice. Imagine browsing through an online bookstore like http://www.Amazon.com. and downloading a novel into your electronic book via the modem in its spine. Transmitting Moby Dick would take about a minute. You could download a few titles, so you’ll have a few good reads to choose from while you’re relaxing at the beach. If your first choice is not to your liking, a new title becomes available at the push of a button.
    Jacobson thinks an electronic book will be affordable—around $200 for a basic read-only model to about $400 for one that would record your margin scribbles. Some hurdles remain, though, before you can take an electronic book with you anywhere. Paper is produced in long sheets, and Jacobson is still working on the best method to integrate electronic ink into that process. To avoid having to use thousands of tiny wires on each page, the ink itself must be conductive. Such ink was recently demonstrated in the lab but has yet to be produced in volume. “Essentially,” notes Jacobson, “we’re trying to print chips.”
    Jacobson is confident, however, that this can be done on a large scale. If Jacobson succeeds, he will have made the book for the 21st century.
选项 A、The Bible.
B、A single volume.
C、New Age tome.
D、An electronic book.
答案 D
解析 本题是一道细节题。你将需要的惟一一本书是什么?不同的人会有不同的回答，因此必须根据文章来选择答案。A项圣经，B项单卷书，C项新时代巨著，D项电子书，这四个答案在文章第一段中都被提到，但是...from a practical standpoint，it will be the only book you’ll ever need.No.It’s not the Bible or some New Age tome...It’s an electronic book--a single volume that...(从实用观点看，这将是你需要的惟一的一本书。不过，这不是《圣经》，也不是新时代巨著……，这是一本电子书--一本单卷书……)由此不难判断出正确答案应为D项。
