Questions 1 to 5 are based on the following passage. They're still kids, and althou g h there's a lot that the experts don't y er know about them. one thing they do agree on is that what kids use and expect from their world has changed rapidly. And it's all because of technology . To the psyc h ologists, sociologists, and generational and media e x perts who study them , their digital gear sets this new group apart, e ven from their tech-s avv y ( 精通科技的 ) Millennial e lders . They want to be constantly connect e d and available in a way even their older siblings don't quite get. These differences ma y appear slight , but they si g nal an all-encompa s sing sens i bility that some say marks the dawning of a new generation . The contrast between Millennials and this younger group was so e vident to psychologist Larry Rosen of Califor n ia State University that he has declared the birth of a new generation in a new book , Rewired : Understanding the iGener a tion and the Way The y L ea rn , out next month. Rosen sa y s the tech-dominated life experience of those born since the e arly 1990s is so different from the Millennials he wrot e about in his 2007 book that they warrant th e distinction of a new generation, which he has dub b ed the "iG e neration". The technolo g y is the easiest way to s e e it , but it's also a mindset , and the mindset goes with the little 'i', which I'm taking to stand for 'individualized'," Rosen sa y s. "Ever y thing is defined and individualized to 'me'. My music choices are defined to 'me'. What I watch on TV any instant is defied to 'm e ' . " He sa y s the iGeneration includes today's teens and middle-schoolers. but it's too soon to tell about e lementary-school ages and younger Rosen says the iGeneration believes anything is possible. "If the y can think of it , somebody probably has or will invent it , " he sa y s. "The y expect innovation." They have high expectations that whatever they want or can use "will be able to be tailor e d to their own needs and wishes and desires". Rosen says portability is key. The y are inseparable from their wir e less devices , which allow them to text as well a s talk, so they can be constantly connected — even in class, where cellphones are supposedly banned . Many researchers are trying to determine whether technology somehow causes the brains of young people to be wired diff e ren t ly. "The y should be distracted and should perform more poorly than they do , " Rosen says. “But findin g s show teens survive distractions much better than we would predict b y their age and their brain development. " Bec ause these kids are more immersed and at younger ages , Rosen says , the educational system has to change significantly. “The growth curve on the use of technology with children is exponential ( 指数的 ), and we run the risk of being out of step with this generation as far as how they learn and how they think , " Roscn sa ys. “We have to g ive them options because they want their world individualized .
