问题     In promising to fuse media as diverse as television, telephone communication, video games, music and data transmission, , the era of digital convergence goes better than yesterday’s celebrated "information superhighway". Yet achieving this single technology is far from straightforward. There are currently three major television broadcast standards, and they are all incompatible with each other. But this is nothing compared to the many technologies supporting the Internet, each with a different bandwidth and physical media The prob lems faced in designing platforms and communication systems that will be accepted across the world can appear insuperable.
    Even once global standards are assured, however, a further obstacle lies in wait The Internet is plagued by long, erratic response times because it is a pull-technology, driven by patterns of user demands. Push technology, on the other hand, reverses the relationship: servers simply send information to passive users, as in television and radio. But if some form of combination between one-way television flow and interactive Internet is to be the basis of our future media, it is hard to see how it could be operated. Moreover, the problem of fusing Internet with television is also one of defining the services offered. Information, entertainment and relaxation appear at first to be quite different needs. Serious doubts remain over whether consumers will be interested in having to make the sort of mental effort associated with computing while also settling down in front of a sitcom.
    Besides the issue of consumer habits, infrastructure costs are set to be immense, and will have to be met by national states or the private sector before being passed on to users. Platforms do not necessarily have to be expensive. The mobile phone is a good example of how something that is technologically sophisticated can almost be given away, with its cost recovered through service charges. Users are then coerced through clever marketing to upgrade to newer phones with more features to reinforce their dependence.
    Whatever the outcome, it is obvious that technology will play an increasing part in our everyday lives. Beyond technology, digital convergence embraces the services, industrial practices and social behavior that form modern society. We have in our hands the technology to construct the most sophisticated machines ever built, but if they are unusable, simply because of their operating instructions, then recent lessons have taught us they will not survive. Whatever we design must be simple, reliable and useful. Perhaps this is where artificial intelligence will come in.
By digital convergence, the writer means______
选项 A、diversification of communication systems.
B、integrating a wide range of means of media.
C、adaptation of global standards to consumer habits.
D、detaching entertainment from communications.
答案B
解析 题干问：“讲到数字集成，作者的意思是……”。正确选项为B“集合了多种多样的媒体手段”，此题定位于全文的第一句即背景句，并且在最后一段作者又重新提及了这个观点，除此之外文中有许多概念如“combination”、“fuse”与这个概念相呼应。而选项A“通信系统的多样化”，选项C“让全球的标准适合于消费者的习惯”和选项D“把娱乐和通信分开”都不是这个概念在文章所有的含义。
