问题     Scientists Johan Feenstra and Rob Hayes think they’ve figured out how a process called electrowetting can make paper that can do anything a videoscreen does. So far, though, all they’ve got to show for their efforts is a tiny piece of e-paper one centimeter square—only 225 pixels, or picture elements. That won’t be nearly enough for headlines and news videos. The only hint of the technology’s potential is a laptop presentation the inventors have set up. It features Professor Snape, Harry Potter’s teacher, holding an electronic newspaper with an embedded video clip. " That’s what we want," says Hayes.
    They’re likely to get it. Late last month in Tokyo, Sony took an important leap in this direction by introducing Librie, an e-book reader. Although it’s available only in black and white, Librie has the most important characteristic of paper: it reflects natural light. That means it can be read on sunny days or viewed from any angle. You can even choose your own font size. Is this finally the beginning of the end of paper?
    The answer is closer to "yes" than you may think. The holdup so far has been user-unfriendly screens, but now e-paper no longer relies on back-lit displays. A reflective display is easy on the eyes, with twice the contrast of computer screens and up to six times the brightness. It uses power only when changing the page, so a battery can last 300 hours. Several firms are competing for leadership. The Philip’s display on Librie uses technology from Massachusetts-based E-Ink Corp. An electric charge moves either black or white capsules to the surface of the page in patterns that form images. Gyricon Media uses rotating balls with one black side and one white side for signs and billboards. Other companies are focusing on improvements in liquid-crystal displays.     The next challenge is to add color. One option for books would be a simple color filter, but that would block two thirds of the light. Guofu Zhou, who runs the E-Ink project for Philips, thinks products with colored ink can be ready for the market within seven years. He’s now focusing on e-paper that can display 16 or more gradations of gray, which would come in handy in medical imaging or to display black-and-white photographs at home.
    Labs around the world are also racing to design a robust yet flexible backing. Philips researchers are working on a technology for laminating E-Ink on a plastic layer instead of glass, which would then roll into a pen-sized tube. A flexible product for mobile phones and digital cameras can be ready in three to five years.  
The greatest advance that Librie has is that______.
选项 A、it is about the size of a paperback
B、it will be a great success in market
C、it works just like a real book
D、it equals many books in content
答案C
解析 推断题。由题干中的Librie定位至第二段第二句：索尼公司取得了重大进步，它推出了一种电子书籍阅读器Librie。接着对其功能进行介绍：虽然Librie是黑白的，但是它具有纸质书籍的最重要的特性——反射自然光。这最终意味着你可以在晴天，或从任何角度阅读。因为Librie具有了与一般纸质书籍一样的最重要的特性，由此可以推断[C]正确。该段倒数第二句提到You can even choose your own fontsize，这里是说读者可以选择书上字体的大小，但并未对Librie的尺寸进行说明，[A]“与平装本书籍大小一样”没有依据，故排除。文中并未对Librie的市场前景进行预测，也没有提到该阅读器的容量，因此排除[B]和[D]。
