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.  
According to the passage, it is possible that e-paper______.
选项 A、will soon be commercialized and within reach
B、will be printed on paper with E-Ink
C、will replace the traditional paper
D、will be made of plastic layer instead of glass
答案A
解析 推断题。由于本题为全文最后一题，浏览各选项可看出，该题是对电子纸张前景的预测，因此答案最有可能在末段。该段指出：世界各地的实验室都在争先恐后地设计强大的可以通用的支持系统。飞利浦的研究者在研究一项技术，将电子墨水碾压在塑料层而不是玻璃层上，之后就卷成一个和笔差不多大的管子。而三到五年内我们就会看到能与手机和数码相机通用的产品。由此可以判断电子纸张前景美妙，不久之后就可以市场化，故[A]为答案。[B]是对电子纸张的字面曲解，与文中内容无关，故排除。文章只是在第二段末提到Is this finally the beginning of the end of paper?末段并未就此进行评论，[C]无依据，故排除。[D]是末段第二句中给出的细节内容，是已经采取的行动，不是对未来的预测，故排除。
