Why an electronic book？ Computers can store a ton of data and their laptop companions make all that information portable. True enough. But laptops(便携式电脑) and similar portable information de vices 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.
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.
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. Be cause the information is in electronic form, it can be easily manipulated.
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.
According to the passage, which book is the only book you'll ever need？
A．Americans like sports and sports reveal much about the changing ethnic structure of the United States
B．A single volume.
C．New Age tome.
D．An electronic book.

The Web Lifestyle
If you asked people today why they used the telephone to communicate with their friends or why they turned to the television for entertainment, they would look at you as if you were crazy. We don't think a- bout a telephone or a television or a car as being oddities. These things have become such an integral part of life that they are no longer noticed, let alone remarked upon.
In the same way, within a decade no one will notice the Web. It will just be there an integral part of life. It will be a reflex to turn to the Web for shopping, education, entertainment and communication, just as it is natural today to pick up the telephone to talk to someone.
There is incredible interest in the Web. Yet it is still in its infancy. The technology and the speed of response are about to leap forward. This will move more and more people to the Web as part of their everyday lives. Eventually, everyone's business card will have an electronic, tail address. Every lawyer, every doctor and every, business—from large to small—will be connected.
In the United States elections, people now turn to the Internet to see real-time results. The Pathfinder mission to Mars and the problems with the Mir space station drew millions of people to the VI kb for more up -to- date detail than were available elsewhere.
A change like this is often generational. Older people have to learn something new outside their everyday experiences, while kids who grow up with a new technology simply treat it as given. College campuses in particular are providing the ingredients to generate the critical mass for a Web-ready culture.
Today in the United States, there are over 22 million adults using the Web, about half of whom access the Internet at least once a day. Meanwhile, the variety of activities on the Web is broadening at an amazing rate. There is almost no topic for which you cannot find fairly interesting material on the Web. Many of these sites are getting excellent traffic flow. Want to buy a dog？ Or sell a share？ Or order a car？ Use the Internet. Where are we going to get the time to live with the Web？ In some instances, people will actually save time because the Web will make doing things more efficient than in the past. Being able to get information about a major purchase, for example. Or finding out how much your used car is worth. Or what is your cheapest way of getting to Florida. That is very easy to find on the Web, even today. In other instances, people will trade the time they now spend reading the paper, or watching television, for information or entertainment they will find on the computer screen. Americans, particularly young ones, will spend less time in front of a television screen, more on the Web.
One great benefit of the Web is that it allows us to move information online that now resides in paper form. Several states in America are using the Web in a profound way. You can apply for various permits or submit applications for business licenses. Some states are putting up listings of jobs—not just state government jobs, but all the jobs available in the state. I believe, over time, that all the information that governments print, and all those paper forms they now have, will be moved on to the Internet. Electronic commerce notches up month-by-month too. It is difficult to measure, because a lot of electronic commerce involves existing buyers and sellers who are simply moving paper-based transactions to the Web. That is not new business. Microsoft, for example, purchases millions of dollars of PCs online instead of by paper. How- ever, that is not a fundamental change; it has just improved the efficiency of an existing process. The biggest impact has occurred where electronic commerce matches buyers and sellers who would not previously have found each other. When you go to a book site and find an obscure book that you never woul

Electric Tales—21st Century Books
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
A．The Bible.
B．A single volume.
C．New Age tome.
D．An electronic book.
第10题
OPEN-OUTCRY trading (公开叫价交易) is supposed to be a quaint, outdated practice, rapidly being replaced by sleeker, cheaper electronic systems. Try telling that to the New York Mercantile Exchange (NYMEX), the world's largest commodities exchange. On November 1st the NYMEX opened an open-outcry pit in Dublin to handle Brent crude futures (布伦特原油期贷), the benchmark contract for pricing two-thirds of the world's oil.
The NYMEX is trying to snatch liquidity from London's International Petroleum Exchange (IPE), which trades the most Brent contracts; the New York exchange has hitherto concentrated on West Texas Intermediate, an American benchmark grade. The new pit is a response to the IPE's efforts to modernize. On the same day as NYMEX traders started shouting Brent prices in Dublin, the IPE did away with its morning open-outcry session: Now such trades must be electronic, or done in the pit after lunch.
The New York exchange claims that customers, such as hedge funds or energy companies, prefer open-outcry because it allows for more liquidity. Although most other exchanges are heading in the opposite direction, in commodity markets such as the NYMEX, pressure from "locals" self-employed traders is helping to prop up open-outcry, although some reckon that customers pay up to five times as much as with electronic systems. Even the IPE has no plans to abolish its floor. Only last month it signed a lease, lasting until 2011, for its trading floor in London.
Dublin's new pit is "showing promise", says Rob Laughlin, a trader with Man Financial, despite a few technical glitches. On its first day it handled 5,726 lots of Brent (each lot, or contract, is 1,000 barrels), over a third of the volume in the IPE's new morning electronic session. By the year's end, predicts Mr. Laughlin, it should be clear whether the venture will be viable. It would stand a better chance if it moved to London. It may yet: It started in Ireland because regulatory approval could be obtained faster there than in Britain.
Ultimately, having both exchanges offering similar contracts will be unsustainable. Stealing liquidity from an established market leader, as the NYMEX is trying to do, is a hard task. Eurex, Europe's largest futures exchange, set up shop in Chicago this year, intending to grab American Treasury-bond contracts from the Chicago Board of Trade. It has made little headway. And the NYMEX has dabbled in Brent contracts before, without success.
Given the importance of liquidity in exchanges, why do the IPE and the NYMEX not band together？ There have been merger talks before., and something might yet happen. Some say that the freewheeling NYMEX and the more staid IPE could never mix. For now, in any case, the two exchanges will slug it out across the Irish Sea as well as across the Atlantic.
Which of the following is NOT true about open-outcry trading？
A．It is obsolete compared with electronic systems.
B．It concerns more about liquidity.
C．It is less costly than electronic systems.
D．It is impossible to be abolished entirely in a short term.
