问题     (1) Never in the history of the mobile phone has there been so much hype about a new technology ahead of its launch than there is with 5G. It seems that the mobile phone operators, handset manufacturers and equipment vendors are locked into a massive global game of one-upmanship, seeking to claim to be the first to achieve something groundbreaking with the technology. But the stakes are high—the mobile industry also desperately needs 5G, whether for new revenue sources, market share or to drive growth.
    (2) Since mobile phones first appeared in the mid-1980s, the industry has launched several new "generations" of network and technology. Those early "brick" phones of the 1980s were replaced by the 2G (1990s) GSM, digital and international roaming service. 3G (2000s) offered improved internet connectivity before 4G (2010s) delivered a truly broadband experience into our hands.
    (3) 5G is now the fifth generation, but despite considerable media attention and focus on its massively enhanced data capability, focusing on its speed alone is to miss the point of its significance.
    (4) So, what’s so special about 5G? Capacity and coverage won’t be immediately there at launch but more of both is expected in due course. For the user, 5G speeds will be a big draw, with quoted figures ranging from 100Mbps to 20Gbps. Naturally, this is being delivered in direct response to our seemingly insatiable appetite for more and more online content and, especially, video. But 5G won’t only revolutionize mobile handsets; it could also be an alternative way of providing broadband internet access to homes via Fixed Wireless Access. Then there is the delay, or latency, which defines the responsiveness of the network. For 4G, this is currently around 40 milliseconds. 5G, however, could reduce the latency to 10 milliseconds for enhanced Mobile Broadband (eMBB) applications. This won’t mean much to most people, but it could be critical for the useful development of specialist applications such as virtual reality and connected and self-driving vehicles, where even small delays can make a big difference.
    (5) Progress towards 5G has been rapid. Originally intended for commercial launch in 2020, 5G is already a year ahead of schedule. The first formal standards were approved in December 2017, handsets have emerged in the first quarter of 2019 and U. K. operators have announced commercial launch dates for mid-2019 onwards. But the pace of roll-out will be driven primarily by demand, and given the huge investments in 4G and earlier generation networks, 5G has to be paid for with real revenue.
    (6) So how can the service effectively be monetized? Ultimately, the problem is that 4G is good enough for most mobile customers. And given that most of the benefits of 5G to the operators are either hidden or of little direct benefit to everyday users, what value can be placed on simply having even higher download speeds?
    (7) The success of 5G is therefore going to be dependent on operators and their wholesale partners developing new markets that look beyond traditional consumers of mobile services. It may start with higher capacity for today’s services such as video, or improved functionality for tailored networks for campuses or business sites. Ultimately, however, the investors will have to think big—and look to industries behind connected vehicles, the Internet of Things and the other major technologies of the future. (本文选自 Newsweek) [br] Which of the following is the most appropriate title for the passage?
选项 A、The Outlook for 5G
B、The Advantages of 5G
C、The Speed of 5G
D、The benefit of 5G
答案 A
解析 主旨题本题考查的是在把握全文大意的基础上拟定文章标题。全文是对5G技术的一个梳理，先是提到了人们对它的热切关注，然后介绍了移动通信技术的发展历史，最后展望了5G技术的发展前景。总之，文章主要介绍了呼之欲出的5G技术，并对其前景进行展望，故答案为A。B、C和D均不能概括文章主旨，故排除。
