问题                         Sprint Wants Your IPhone
    Remember the map wars between AT&T Wireless and Verizon Wireless? Sprint Nextel thought it looked like great fun, and it’s joined the fracas with a direct-attack ad of its own.
    A new Sprint ad shows two young dudes lounging on a park bench—or rather, one guy lounges while the other is frantically battling his cell phone. That phone turns out to be an Apple iPhone, and as it turns out, the more relaxed guy, Matt, can help his buddy out.
    "My friend Steve’s iPhone is cool, but it’s limited to AT&T’s 3G speeds," he says. "So I’m gonna use the Overdrive 4G mobile hotspot to make it up to 10 times faster. While that’s happening, I’m gonna enjoy this tasty snack." He pulls out a Sprint-connected portable Wi-Fi hotspot and—of course—a tasty apple, and Steve’s 3G troubles are over.
    Cue the legal fireworks. If AT&T got incensed over Verizon using AT&T’s own 3G coverage maps as a weapon, you have to think that this no-nonsense critique of the AT& T network will cause some aggravation as well.
    Verizon could at least back its claims with some solid data, even if AT&T’s spotty coverage has reportedly improved since then. Sprint is picking cherries to climb the Apple tree here. That "10 times the speed" claim rests on a worst-case 3G connection and the most positive 4G data Sprint can muster on its own network. "Triple the speed" might be closer to the truth on average.
    Besides, Sprint’s 4G network has only opened up in 33 cities so far, with a heavy Midwestern concentration. Major population centres like San Francisco and New York, where AT&T’s network quality has drawn the most fury so far, are not covered at all—so Matt’s clever solution wouldn’t help Steve at all in most cases. Sprint’s own coverage information will make that very clear if you try to order an Overdrive gadget.
    With iPhones, iPads, and Google Androids flooding the market, all the major service providers need to figure out how to handle heavy Web use and streaming video for previously unheard-of millions of customers nationwide. This Sprint trinket and the accompanying ad campaign seems designed to steal iPhone users from AT&T, but Sprint isn’t really ready to take most of them on anyway.
    By the time Sprint has covered most of the country, chances are that Verizon and AT&T have gotten their own 4G installations in gear. After the undisputed failure of the Palm Pre smartphone, Android handsets look like better ammunition for Sprint’s war against the Big Two than the 4G network is.
Matt’s clever solution wouldn’t help Steve at all in most cases, because

选项 A、Sprint’s 4G network has only opened in Midwestern area.
B、AT&T’s network has covered most of the area.
C、The coverage of Sprint’s network is so limited.

答案C

解析 题干意为:Matt的妙招在大多数情况下不能解决Steve的难题,原因是什么。A项意为:Sprint的4G网络仅在中西部地区开通,B项意为:AT&T的网络已经覆盖了大多数地区,C项意为:Sprint公司的网络覆盖率很有限。原文第六段第一行提到:“Sprint公司的4G网络到目前仅在33座城市开通,而且主要集中在中西部地区。”由此可推知其他地区的个别城市也有其网络服务,故A项错误,由仅在33座城市有服务可知C项正确。第六段第二行指出:“AT&T公司的网络在主要的人口中心,如旧金山和纽约,受到人们的抨击,但是(Sprint公司)没有覆盖到这些地区”,在此文中只交待了AT&T公司在这些城市有业务,但是没有说明其是否在大多数地区有业务,故B项错误,故答案为C。
