题目内容：

Last week, about 600 teenagers in the US imagined a future changed by technology in which their lessons are taught by robots and they learn about celebrities and alien languages. They believe they will use jet packs, and hoverboards (旋转飞盘), as everyday transport.

All the participants (参加者) of the survey are teenagers born into the Internet age. The study is to show how the first cyber (与电脑有关的) 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 interchangeable microchips (微型芯片) so that one person can teach all subjects.

More than one in two believe hoverboarding will be popular, while one-third say that wearing rocket boots will be their favourite activity. Another third think jet packs will be popular. Nearly 30 percent think football and bike-riding will remain popular.

When it comes to the courses, they think future generations will be learning about robot building (63 percent), alien languages (47 percent), celebrities (26 percent) and R&B music (22 percent).

Children will wear virtual reality helmets (可视头盔) to bring lessons to life, say 40 percent, while over 20 percent believe they will not need lessons because microchips put in their head will send relevant (相关的) information into the brain.

Matt Whyman, adviser to the chief medical officer on youth issues at American Online, said, “The kids seem very aware of the liberating qualities of technology.”
