Thanks to the GPS, the apps on your phone have long been able to determine your general location. But what if they could do so with enough precision that a supermarket, say, could tempt you with digital coupons depending on whether you were hovering near the white bread or the bagels? It may sound far-fetched, but there"s a good chance the technology is already built into your iPhone or Android device. All it takes for retailers to tap into it are small, inexpensive transmitters called beacons. Here"s how it works: using Bluetooth technology, handsets can pinpoint their position to within as little as 2cm by receiving signals from the beacons stores install. Apple"s version of the concept is called iBeacon; it"s in use at its own stores and is being tested by Macy"s, American Eagle, Safeway, the National Football League and Major League Baseball. Companies can then use your location to pelt(连续攻击)you with special offers or simply monitor your movements. But just as with GPS, they won"t see you unless you"ve installed their apps and granted them access. By melding your physical position with facts they"ve already collected about you from rewards programs, brick-and-mortar businesses can finally get the potentially profitable insight into your shopping habits that online merchants now take for granted. The possibilities go beyond coupons. PayPal is readying a beacon that will let consumers pay for goods without swiping a card or removing a phone from their pocket. Doug Thompson of industry site Beekn. net predicts the technology will become an everyday reality by year"s end. But don"t look for stores or venues to call attention to the devices. " People won"t know these beacons are there," he says. "They"ll just know their app has suddenly become smarter. "

单选题 The GPS on your phone can______.

单选题 According to the second paragraph, which one of the following is true?

【正确答案】 C

【答案解析】解析：选项[A]对应最后一句：Apple’s version of the concept is called iBeacon；it’s in use atits own stores and is being tested by Macy’s，American Eagle，Safeway，the National FootballLeague and Major League Baseball．该句明确指出它在苹果自己的店内投入使用，而不是该项说的应用于新的手机中，故该项错误。选项[B]对应首句：It may sound far—fetched，but there’s agood chance the technology is already built into your iPhone or Android device．其中，it指代上文提到的“精确定位”，即该项的precise location，该句的“there’s a good chance很有可能”与该项的“remote遥远”明显相反，故该项错误。选项[C]对应该段第三句：Here’s how it works：usingBluetooth technology，handsets can pinpoint their position to within as little as 2 cm by receiving sig—nals from the beacons stores install．该句大意为：手机可以通过接收“信号器”发出的信号精确定位，误差仅有2厘米。通过该句话的理解可以判断选项[C]是正确的。选项[D]对应该段第二句：All it takes for retailers to tap into it are small，inexpensive transmitters called beacons．其中该项的“hard-to-reach难以获得”一词是无中生有，故该项错误。综上所述，答案为选项[C]。

单选题 Precise location may be used to______.

【正确答案】 D

【答案解析】解析：根据题干中的precise location以及出题顺序定位到第三段。第三段首句提出：Com—panies can then use your location to pelt you with special offers or simply monitor your movements．答案来自该句location之后的to pelt you with special offers or simply monito your movements。其中pelt you with special offers与[D]项vend special commodities to customers表述相符。而[A]和[B]两项属于无中生有；选项[C]不是该题对应的答案。综上所述，答案为选项[D]。

单选题 The phrase " brick-and-mortar businesses"(Para 3, Line 4)is relative and closest to______.

【正确答案】 B

【答案解析】解析：该题考查的是brick-and-mortar businesses这一词组，而上下文出现了许多名词词组都有可能与其相关，我们即使看不懂brick—and—mortar，至少知道businesses意为“生意，企业”。而这个词与四个备选项中哪个最接近，这是非常容易判断的。显然不可能等于pro-grams，insight或者habits，而是等同于stores。故判断选项[B]为答案。

单选题 PayPal is preparing a beacon that will______.

【正确答案】 C

【答案解析】解析：根据题干定位到最后一段第二句：PayPal is readying a beacon that will let consumerspay for goods without swiping a card or removing a phone from their pocket．答案在于that后面的内容。其中“will let consumers pay for goods without swiping a card or removing a phone from theirpocket”意为“让消费者无需刷卡或者从口袋中取出手机就能够付款”，与选项[C]“让消费者更方便地付款”表述一致。故选项[C]为答案。
