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 . " 1. Compared with their Millennial e lders, the iGeneration kids ________. A) communicate with others by high-t e ch methods continually B) prefer a virtual life to a real one C) are e quipped with more modern digital techniques D) know more about technology than their elders 2 . Why did Larry Rosen name the new generation as iGeneration? A) Because this generation is featured by the use of high-tech devices. B) Because this g eneration stresses an individualized style of life. C) Because it is the author himself who has discovered the new generation. D) Be c aus e this g eneration shares a common mindset. 3. What can we learn about the iGeneration according to Rosen? A) The generation is crazy about inventing and creating new things. B) Everything must be adapted to the peculiar need of the generation . C) The generation catches up with the development of technology. D) High-tech products such as wireless devices go with the generation. 4 . Rosen's findings suggest that technolog y_______. A) has an obvious effect on the function of the iGeneration's brains B) has greatly affected the iGeneration's behavior and academic performance C) has no significantly negative effect on the brains of the iGeneration to be wired D) has caused serious distraction problems for the iGcneration, affecting their daily performance 5. According to the passage, education has to _______. A) adapt itself to the need of the new generation B) use more technologies to cater for the iGeneration C) risk its system to some extent for the iGeneration D) be conducted online for the iGeneration's individualized need
