单选题Who's Really Addicting You to Technology? A. 'Nearly everyone I know is addicted in some measure to the Internet,' wrote Tony Schwartz in The New York Times. It's a common complaint these days. A steady stream of similar headlines accuse the Net and its offspring apps, social media sites and online games of addicting us to distraction. B. There's little doubt that nearly everyone who comes in contact with the Net has difficulty disconnecting. Many of us, like Schwartz, struggle to stay focused on tasks that require more concentration than it takes to post a status update. As one person ironically put it in the comments section of Schwartz's online article, 'As I was reading this very excellent article, I stopped at least half a dozen times to check my email.' C. There's something different about this technology: it is both invasive and persuasive. But who's at fault for its overuse? To find solutions, it's important to understand what we're dealing with. There are four parties conspiring to keep you connected: the tech, your boss, your friends and you. D. The technologies themselves, and their makers, are the easiest suspects to blame for our diminishing attention spans. Nicholas Carr, author of The Shallows: What the Internet Is Doing to Our Brains, wrote, 'The net is designed to be an interruption system, a machine geared to dividing attention.' E. Online services like Facebook, Twitter and the like, are called out as masters of manipulation—making products so good that people can't stop using them. After studying these products for several years, I wrote a book about how they do it. I learned it all starts with the business model. Since these services rely on advertising revenue, the more frequently you use them, the more money they make. It's no wonder these companies employ teams of people focused on engineering their services to be as engaging as possible. These products aren't habit-forming by chance; it's by design. They have an incentive to keep us hooked. F. However, as good as these services are, there are simple steps we can take to keep them at bay. For example, we can change how often we receive the distracting notifications that trigger our urge to check. According to Adam Marchick, CEO of mobile marketing company Kahuna, less than 15 percent of smartphone users ever bother to adjust their notification settings—meaning the remaining 85 percent of us default to the app makers' every preset trigger. Google and Apple have made it far too difficult to adjust these settings so it's up to us to take steps to ensure we set these triggers to suit our own needs, not the needs of the app makers'. G. While companies like Facebook harvest attention to generate revenue from advertisers, other technologies have no such agenda. Take email, for example. This system couldn't care less how often you use it. Yet to many, email is the most habit-forming medium of all. We check email at all hours of the day—we're obsessed. But why? Because that's what the boss wants. For almost all white-collar jobs, email is the primary tool of corporate communication. A slow response to a message could hurt not only your reputation but also your livelihood. H. Your friends are also responsible for the addiction. Think about this familiar scene. People gathered around a table, enjoying food and each other's company. There's laughter and a bit of kidding. Then, during an interval in the conversation, someone takes out their phone to check who knows what. Barely anyone notices and no one says a thing. I. Now, imagine the same dinner, but instead of checking their phone, the person belches (打嗝)—loudly. Everyone notices. Unless the meal takes place in a beer house, this is considered bad manners. The impolite act violates the basic rules of etiquette. One has to wonder: why don't we apply the same social norms to checking phones during meals, meetings and conversations as we do to other antisocial behaviors? Somehow, we accept it and say nothing when someone offends. J. The reality is, taking one's phone out at the wrong time is worse than belching because, unlike other minor offense, checking tech is contagious. Once one person looks at their phone, other people feel compelled to do the same, starting a chain reaction. The more people are on their phones, the fewer people are talking until finally you're the only one left not reading email or checking Twitter. From a societal perspective, phone checking is less like belching in public and more like another bad habit. Our phones are like cigarettes—something to do when we're anxious, bored or when our fingers need something to toy with. Seeing others enjoy a smoke, or sneak a quick glance, is too tempting to resist and soon everyone is doing it. K. The technology, your boss, and your friends, all influence how often you find yourself using (or overusing) these gadgets. But there's still someone who deserves scrutiny—the person holding the phone. L. I have a confession. Even though I study habit-forming technology for a living, disconnecting is not easy for me. I'm online far more than I'd like. Like Schwartz and so many others, l often find myself distracted and off task. I wanted to know why so I began self-monitoring to try to understand my behavior. That's when I discovered an uncomfortable truth. I use technology as an escape. When I'm doing something I'd rather not do, or when I'm someplace I'd rather not be, I use my phone to port myself elsewhere. I found that this ability to instantly shift my attention was often a good thing, like when passing time on public transportation. But frequently my tech use was not so benign. When I faced difficult work, like thinking through an article idea or editing the same draft for the hundredth time, for example, a more sinister screen would draw me in. I could easily escape discomfort, temporarily, by answering email or browsing the web under the pretense of so-called 'research.' Though I desperately wanted to lay blame elsewhere, I finally had to admit that my bad habits had less to do with new-age technology and more to do with old-fashioned procrastination (拖延). M. It's easy to blame technology for being so distracting, but distraction is nothing new. Aristotle and Socrates debated the nature of 'akrasia'—our tendency to do things against our interests. If we're honest with ourselves, tech is just another way to occupy our time and minds. If we weren't on our devices, we'd likely do something similarly unproductive. N. Personal technology is indeed more engaging than ever, and there's no doubt companies are engineering their products and services to be more compelling and attractive. But would we want it any other way? The intended result of making something better is that people use it more. That's not necessarily a problem, that's progress. O. These improvements don't mean we shouldn't attempt to control our use of technology. In order to make sure it doesn't control us, we should come to terms with the fact that it's more than the technology itself that's responsible for our habits. Our workplace culture, social norms and individual behaviors all play a part. To put technology in its place, we must be conscious not only of how technology is changing, but also of how it is changing us.

单选题Researchers from the Shaare Zedek Medical Center and Bar-Ilan University just released a report explaining how a new type of eye drop 27 with 'nanoparticles' could replace the need for glasses or contacts. It's a bit 28 and requires a brief doctor visit, but it apparently works like a charm. The three-step process starts with a 29 of the individual's eye refraction (屈光度), which can be performed with a smartphone. Then, doctors create a very specific laser pattern which is applied to the eye for less than one second. The laser creates tiny 30 in the surface of the cornea. Lastly, special eye drops are applied. 'These nanoparticles go into the shallow ablated patterns generated on the surface of the cornea,' Zeev Zalevsky explained to Digital Trends. 'They change the refraction index inside of those patterns. This corrects the 31 problem the user has. The process of correction can be done at home without the need of a medical doctor.' The procedure is less 32 than traditional laser eye surgery in that it only affects the exterior of the eye and does not require an extensive procedure. However, because the 33 to the eye are so minor, the tiny etchings in the cornea eventually heal themselves and vision 34 degrades. The researchers believe the positive effects of the treatment will last one to two months. Heading to the eye doctor for a reapplication of the laser every two months sounds pretty 35 , but the technology is still in its infancy. Going forward, the researchers are planning additional testing and hope to have something 36 a commercial product available within the next two years.
