瞧!这就是美国加利福尼亚青年罗热·希凯伊发明的公路“雪撬”运动。这项运动简单易行,只需一块厚木板,下面安几个小轮子即可,既无方向盘又无刹车闸,也无任何保护装置。运动员躺在木板上,沿着公路大斜坡往下滑,最高速度可达每小时120公里。如果想停下来,只有一个办法:人坐起来并用双脚接触地面以减速。这项运动十分危险,但却很富于刺激。希凯伊已42次受伤,但仍没能阻止他继续探险 Los Angeles: This is the “Sled” road race invented by Rohstyskey, a young California man. The sport is simple and easy: just a piece of plank, just a few small wheels below, no steering wheel, no brakes and no protection. Athletes lying on the board, along the highway down a large slope, the maximum speed of up to 120 kilometers per hour. If you want to stop, there is only one way: people sit up and touch the ground with both feet to slow down. The sport is dangerous but very exciting.
