Bored at school now?  How do you think it will look in the future? Last week, about 600 teenagers in the U.S. imagined a future changed by technology in which their lessons are taught by robots and they learn about celebrities (名人)and alien(外星人)languages.
According to a survey published last week by the U.S. ,Internet service provider American Online(AOL), only one in 100 thinks that in the future they will walk from home to school; the rest believe they will use jet packs, and hover boards(滑板) as everyday transport.
All the participants(参与者)of the survey are teenagers born into the Internet age. The study is to show how the first cyber (网络的)generation dream about a future life created by advanced technology.
Most believe there will still be schools to go to, but that technology will play an increasingly important role in learning. The 600 teens surveyed think there will still be teachers, but 37 percent imagine them to be robots. Some 24 percent believe that teachers will still be human but they will have inter-changeable microchips so that one person can teach all subjects.
More than one in two believe hover boarding will be popular, while one-third say that wearing rocket boots will be their favorite activity. Another third think jet packs will be popular. Nearly 30 percent think playing football and bike-riding will remain popular.
When it comes to the curriculum(课程), they think future generations will be learning about robot building(63 percent), alien languages(47 percent) celebrities(26 percent) and R’n’B music(22 percent).
Children will wear virtual(虚拟的)reality helmets(头盔) to bring lessons to life, say 40 percent, while over 20 percent believe they will not need lessons because microchips implanted(植入)in their head will send relevant information into the brain. Matt Whyman, adviser to the chief medical officer on youth issues of AOL, said: “ The kids seem very aware of the liberation qualities of technology.”
