2、can seem like a fad that has all the durability of CB radios or Duran Duran, but theyre important early signs of a new era of technology that will drive investment and innovation for years. Tech companies are pushing out waves of wearable technology products all of them clumsy and none of them yet r
3、eally catching on. Samsung is excitedly hawking its Galaxy Gear smart watch, and Google, Apple, Qualcomm(高通公司 ), and others are expected to come out with competing versions. Google Glass gets lots of gee-whiz attention, and every other day, someone new introduces a fitness tracker, a GPS kid-monitor
4、ing bracelet, or yeah, seriously interactive underwear. These are all part of a powerful trend: Over the past 40 years, digital technology has consistently moved from far away to close to us. Go back long enough, and computers the size of Buicks stayed in the back rooms of big companies. Most people
5、 never touched them. By the late 1970s, technology started moving to office desks first as terminals connected to those hidden computers, and then as early personal computers. The next stage: We wanted digital technology in our homes, so we bought desktop PCs. A “portable“ computer in the mid-1980s,
6、 like the first Compaq, was the size of a carry-on suitcase and about as easy to lug as John Goodman. But by the 1990s, laptops got better and smaller, for the first time liberating digital technology from a place and attaching it more to a person. Now we want our technology with us all the time. Th
7、is era of the smartphone and tablet began with the iPhone in 2007. The “with us“ era is accelerating even now: IBM announced that its making its powerful Watson computing the technology that beat humans on Jeopardy! available in the cloud, so it can be accessed by consumers on a smart device. In tec
8、hnologys inexorable march from far away to close to us, and now with us, there are only three places left for it to go: on us, all around us, and then in us. “Wearable is the next paradigm shift, “ says Philippe Kahn, who invented the camera phone and today is developing innards for wearable tech. “
9、We are going to see a lot of innovation in wearable in the next seven years, by 2020. “ Hard to know which products will catch on. Glasses are an obvious way to wear a screen, but most people dont want to look like a tech geek(极客 ). The masses might get interested if Google Glass can be invisibly bu
10、ilt into hot-looking frames. A start-up called Telepathy is developing a slim arm that holds a microprojector that shoots images back to your eye. Another concept is to build a device with a tiny projector that suspends text or images out in front of you, like a heads-up display. 1 According to the

( D) Because its frame is invisible. 3 Simply walking through an unfamiliar neighborhood can make you feel more paranoid(
14、疑神疑鬼的 )and lower your trust in others. In a study published in the journal PeerJ, student volunteers who spent less than an hour in a more dangerous neighborhood showed significant changes in some of their social perceptions. The researchers goal was to investigate the relationship between lower inc
15、ome neighborhoods and reduced trust and poor mental health. While the association is well known, the scientists, from Newcastle University in the UK, wanted to determine whether the connection was due to people reacting to the environment around them, or because those who are generally less trusting
16、 were more likely to live in troubled areas. Prior research showed that kids who grew up in such neighborhoods were less likely to graduate from high school and more likely to develop stress that can lead to depression. The study took 50 students, sent half of them to a low income, high crime neighb
17、orhood and the other half to an affluent neighborhood with little crime. Before the students ventured into their respective areas, the researchers interviewed the neighborhood residents and found that residents of the high-crime neighborhood harbored more feelings of paranoia(多疑 )and lower levels of
18、 social trust compared to the residents of the other neighborhood. The students in the study were not from either neighborhood, and did not know what the study was about. They were dropped off by a taxi and told to deliver envelopes containing a packet of questions to a list of residential addresses
19、. They spent 45 minutes walking around their assigned neighborhood distributing the envelopes. When the students returned, the researchers surveyed them about their experience, their feelings of trust, and their feelings of paranoia. Despite the short amount of time they spent in the neighborhoods,
20、the students picked up the prevailing social attitudes of the residents living in those environments; those who went to the more dangerous neighborhood scored higher on measures of paranoia and lower on measures of trust compared to the other group, just as the residents had. Not only that, but thei
21、r levels of reported paranoia and trust were indistinguishable from the residents who spent years living there. That came as an intriguing surprise to other experts. Ingrid Gould Ellen, the director of the Urban Planning Program at New York University Wagner Graduate School of Public Service, studie
22、s how the make-up of neighborhoods can impact the attitudes and interactions of people who live in them. In her research, she and her colleagues found that kids who live on blocks where violent crimes occurred the week before they took a standardized test performed worse on those tests than students
23、 from similar backgrounds who were not exposed to a violent crime in their neighborhood before their exam. But the fact that the paranoia and lack of trust set in after just a short time in the more troubled neighborhood suggested how powerful the influence of these environments can be. “In the case
24、 of this UK study, it seems unlikely that study participants were actually exposed to crime during their brief visits. But somehow the physical cr social cues in the neighborhood suggested to them that these were unsafe areas, “ says Ellen. 4 According to Paragraph 3, which of the following statemen
