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." The phrase "brick-and-mortar businesses" (Para. 3) is relative and closest to ______.

调查报告是报告调查研究结果的一种专用文书，是作者有目的地对社会生活的某一事件、某一人物、某一现象、某一问题作深入细致的调查研究，然后用科学的方法进行分析研究而写成的书面报告。调查报告可以作为领导决策的依据，用来推广新生事物、先进典型，也可用来反映工作中存在的问题和揭示某一事件的真相。在实际工作中，调查报告是使用频率较高的一种事物文书。撰写调查报告的能力，被认为是从事相关工作的一项基本能力。不少人认为，调查报告的结构包括现状、原因、对策等部分，一定要写成篇幅很长的大文章才行，否则就可能表达不清楚。其实不然。有不少1000字左右的微型调查报告，很受读者欢迎，其作用并不比大篇幅的调查报告差。 一篇一千多字的调查报告，文风朴实，言简意赅，麻雀虽小，五脏俱全，把事情的原因、造成的危害、解决的办法表达得清清楚楚，使人一目了然。现在，有的调查报告穿靴戴帽，篇幅很长。把有限的信息淹没在冗长的文字里，使人不得要领，助长了不良文风，影响问题的解决。现代社会工作节奏快，汇报工作、反映情况力求信息准确，办法具体，简短明了。在保持一定信息量的前提下，应大力提倡撰写篇幅在千字左右、精悍短小、观点鲜明的微型调查报告。 在调查报告的撰写中，常见的一种现象就是叠床架屋、重复累赘。这些叠床架屋现象，其病因就是在遣词造句上欠缺精度和力度。如“最最坚决拥护”、“非常非常热爱”、“对重大问题要尽快查处”等等。这些都是______。
