1. The Age of Superstuff The Stone Age. The Iron Age. Entire epochs have been named for materials. So what to call the decades ahead? The choice will be tough. Consider: high-fidelity loudspeakers made of transparent plastic film. Windshields that tint with the flip of a switch. Cars that never rust－running on highways without potholes. Replacement hip joints that meld with natural bone. Materials science is bursting with new, practical discoveries, led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the pictures; from houses and cars to cook pots and artificial teeth, the world will someday be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science. 2. 互联网 国际互联网最初是美国国防部建立的一个试验性网络，现在涵盖了世界范围内的2000多万台计算机，估计每年还要增加50万台。它提供电子邮件、数以千计的简报式新闻以及各种数据库服务。你可以用电子邮件把问候语与电视图像、声音、数据等压缩在一起。更重要的是，它通过大量信息量的数据交换促进人们之间的合作。人们已经进行了在互联网现场传输声音和图像的实验。互联网的庞大规模使它有望成为信息高速公路的主干线。但为了支持越来越多的用户和多媒体应用，必须增加频带宽度，这是信息高速公路的核心技术问题。 Internet Internet, originally established as an experimental network for the U.S. Defense Department, now spans more than 20 million computers worldwide, with an estimated 500,000 increase every year. It offers electronic mail, thousands of bulletin board-type news-groups and a variety of database services. The electronic mail allows you to encapsulate your greeting with video images and sound as well as data. More importantly, it enhances collaborative working through an information-rich exchange of data. Experiments on transmitting live audio and video over the Internet have also been conducted. The sheer size of the Internet makes it a candidate for the backbone of the Information Superhighway. But in order to support the growing number of users and the multimedia applications, the available bandwidth will have to increase dramatically, which is the technical problem at the core of the Information Superhighway. 青岛滨海学院精
