问题      The Japanese and U. S. governments both studied the concept of "wired cities" using cable TV to deliver entertainment, information and educational services similar to those discussed today in the context of the digital revolution. On the basis of these hopes, the US government allowed the cable companies to set up local monopolies. In the event, these never delivered anything other than television with the understandable justification that user trials found minimal consumer interest in any of the other service, including interactive TV.
    What, then, is different this time?
    First, computers have become more powerful, cheaper, smaller, easier to use (although they still have a long way to go on this front) and more widely distributed, especially within businesses and especially in the U. S. Many of us now have personal computer (PCs) at home and also interact with computer technology in many other guises-games machines, automatic teller machines (ATMs) and the fifty microcomputers in a typical modern car.
    Second, the Internet. The Internet is a loose network of networks which enables PCs in most large organizations and many homes and small businesses (using a standard connection to a telephone line! to communicate with each other around the world at low cost. The Internet belongs to no one (although it uses telecommunication links which do)and has no central authority; it is really a set of "communication protocols", more like a language than a physical network, which means that any computer, whatever its internal language is, can communicate with any other. The Internet has existed for many years as an academic network, but took off as a mass application only in the mid-1990s. This was partly because of the invention of new software (the World Wide Web and "browsers") which made it easier to find useful information and move between different sites.
    The Internet exhibits a characteristic crucial for all successful communication networks: that their value to each member increases with the number of other members. The same happened with telephones and, more recently, fax machines: neither would be useful except as a status symbol if no one else had one. Once enough other people were on the Web, it became worthwhile for yet more people. In reality, despite all the talk of Websites, "surfing" and cyber-commerce, the main way most people(including the authors)use the Internet today is for electronic mail (e-mail)-typed messages and documents sent from one PC to another. The e-mail population reached" critical mass" in about the mid-1990s.  
With more people on the Web, ______.
选项 A、new surfing software needs to be developed
B、telephone will become more widely used
C、the Internet will become more widely used
D、the Internet will become a status symbol to evaluate people
答案C
解析 推断题。此题是问随着使用网络的人越来越多，会出现什么结果。最后一段提到人们目前使用 Internet的主要方式是收发电子邮件，其他用途如网上冲浪、电子商务使用得很少，Internet的前景很好。因此，C项最符合题意。
