问题     On a more mundane (世俗的) level, third-generation mobile telephones, despite all the delays and the billions squandered on 3G licenses by telecom firms, are still expected to offer consumer highspeed, always-on mobile internet access, complete with video, in the next few years. Rapidly proliferating "wi-fi" (无线局域网) networks already offer wireless access on a local basis. Tiny tracking chips called radio-frequency identification devices are being used as passports. Soon they will be small, powerful and cheap enough to be implanted into everything. Sensors of every kind, including video cameras, should also become much smaller and cheaper. Forrester Research, a technology consultancy, predicts that 14 billion such devices will be connected to the internet by 2005.
    How rapidly such new technology is introduced will depend on a number of factors—the state of the economy, the supply of investment capital and the appetite of consumers for new products or services! Fortunes will be made and lost many times over. But whatever happens, the power of computing and communications looks set to continue to grow, and its price to fall, at a steady rate for the next few decades. That will make it possible, at least in rich countries, to record most human interactions, wherever and whenever they take place, and to store and analyze this ocean of data at low cost.
    For the sake of argument, this survey will assume that we are heading towards a networked society of ubiquitous (到处存在的), mobile communication capable of constant monitoring. Whether this arrives in 20, 30 or 40 years does not really matter. The point is that the destination seems not merely possible, but probable, so it is not too soon to ask: What do we want this technology to do?
    The internet has already thrown up a host of legal and political problems, but these are only a small foretaste of the dilemmas—about privacy, security, intellectual property and the nature of government itself—that will have to be faced over the coming decades. The debate has already begun. This survey will outline some of main issues, and speculate on the way they are likely to go.
At present, a radio-frequency identification device enables people to _____.
选项 A、get small, powerful and cheap passports
B、get wireless access to the "wi-fi" networks
C、get smaller and cheaper sensors of every kind
D、get wireless internet access complete with video
答案B
解析 第1段第3句中的谓语和表语成份表明“无线电频率识别装置”充当“通行证”，结合该段第2句就可以推断出，passport指的就是使用无线网络的通行证，即：有了这种“无线电频率识别装置”，就等于可以连接到无线局域网上，由此可见，B为本题答案。
