    When people talk about the future, we like to think that we will be able to drive out of our garages and take to the skies in our own personal flying car. The advantages are obvious. Some people predict this technology {#blank#}1{#/blank#} complete freedom of movement. We could fly at 480 kilometres per hour,{#blank#}2{#/blank#}traffic lights, busy roads and speeding tickets. However, some people point to the disadvantages of flying cars. They say that there are certain to be problems with traffic control. Another big problem is engine{#blank#}3{#/blank#}. What will happen if the car goes wrong? Also, if they become popular, there is {#blank#}4{#/blank#} to be another big problem: air traffic jam. So we may find flying cars {#blank#}5{#/blank#} with more than a few problems if they are to get off the ground!

    They're still kids, and although there's a lot that the experts don't yet know about them, one thing they do agree on is that what the kids use and expect from their world has changed rapidly. And it's all because of technology.

    To the psychologists, sociologists, and media experts who study them, their digital devices set this new group {#blank#}1{#/blank#}, even from their Millennial (千禧年的) elders, who are quite familiar with technology. They want to be constantly connected and available in a way even their older brothers and sisters don't quite get. These differences may seem slight, but they{#blank#}2{#/blank#} the appearance of a new generation.

    The {#blank#}3{#/blank#} between Millennialelders and this younger group was so evident to psychologist Larry Rosen that he has {#blank#}4{#/blank#} the birth of a new generation in a new book, Rewired: Understanding the ingeneration and the Way They Learn, out next month. Rosen says the technically {#blank#}5{#/blank#} life experience of those born since the early 1990s is so different from the Millennial elders he wrote about in his 2007 book, Me, MySpace and I: Parenting the Net Generation, that they distinguishthemselves as a new generation, which he hasgiven them the nickname of "ingeneration".

    Rosen says portability is the key. They are{#blank#}6{#/blank#}from their wireless devices which allow them to text as well as talk, so they can be constantly connected—even in class, where cell phones are {#blank#}7{#/blank#} banned.

    Many researchers are trying to determine whether technology somehow causes the brains of young people to be wired differently. "They should be distracted and should perform more poorly than they do," Rosen says. "But findings show teens {#blank#}8{#/blank#} distractions much better than we would predict by their age and their brain development."

    Because these kids are more devoted to technology at younger ages, Rosen says, the educational system has to change {#blank#}9{#/blank#} .

    "The growth on the use of technology with children is very rapid, and we run the risk of being out of step with this generation as far as how they learn and how they think. We have to give them options because they want their world {#blank#}10{#/blank#} ," Rosen says.
