Can you imagine riding around the streets of your hometown on a skateboard without wheels? In the late 1980s, film director Robert Zemeckis showed a skateboard floating above the ground in his movie Back To The Future Part II. Now, an American company, Arx Pax, has moved the idea for such a device from a futuristic dream to reality. The new product operates on the same rules that govern magnetism.________________________ 你能想象到在家乡附近的街道踩上一款没有轮子的滑板吗?在20世纪80年代末期,电影导演罗伯特`泽米吉斯(Robert Zemeckis)在他的电影<回到未来 2>中呈现了一款漂浮在地面的滑板. 美国Arx Pax公司现在已经将这种设备理念从未来梦想变成了现实.这种新产品根据磁性原理来工作.______________________
