问题     (46)We’re all too familiar with the concept of technology as a double-edged sword, and wire less is no exception. In fact, the back edge of this rapier is sharp enough to draw blood. Yes, the idea of shedding wires and cables is exhilarating: we can go anywhere and still maintain intimate con tact with our work, our loved ones and our real-time sports scores. (47)But the same persistent connectedness may well lead us toward a future in which our cell phones tag and track us like FedEx packages, sometimes when we’re not aware.
    To see how this might work, check out Worktrack, a product from a California "mobile services’’ company Aligo. The system is sold to employers who want to automate and verify digital time logs on their workers in the field. The first customers are in the heating and air-conditioning business. (48)Workers have GPS-equipped cell phones that locate precisely their positions to computers in the head office; therefore, their journey can be checked against the "Ceo Fence" their employers draw up, indicating the area where their work is situated.
    "If they’re not in the right area, they’re really not working, "says Aligo CEO Robent Smith. "A notification will come to the back office that they’re not where they should be". The system also tracks how fast the workers drive, so the employer can verify to insurance companies that no one is speeding. All of this is perfectly legal, of course, as employers have the right to monitor their workers.
    Worktrack is only one of a number of services devoted to tracking humans. (49)For example, parents use similar schemes to make sure their kids are safe, and many drivers are already allowing safety monitors to keep GPS records on their travels. Look for the practice to really explode as mobile-phone makers continue to incorporate GPS in their handsets.
    The prospect of being tracked "turns the freedom of mobile telephony upside down". (50)In fact, if information from the GPS signals is retained, it would be trivial to retain a log of an individual’s movements over a period of years. An even darker view is proposed by two academics who wrote a paper warning of the advent of "geoslavery." Its definition: "a practice in which one entity, the master, forcibly or stealthily monitors and exerts control over the physical location of another individual to routinely control time, location, speed and direction for each and every movement of the slave."

选项
答案事实上，如果全球定位系统的信号信息被保留，那么长时间地保留某个人的行动记录将变得毫无意义。
解析 本句为主从复合句，主干结构是"would be trivial to retain a log。if引导条件状语从句。翻译if引导的条件状语从句时，可以在主句之前补充"那么"使得语意连贯。主句中it为形式主语，后面的不定式为真正主语，翻译时应把不定式部分作为主语翻译到前面。
