Paragliders wear a wing-shaped parachute, and some attach a frame harness with a motor that looks like a big fan.
伞式滑翔机穿翼形降落伞,有的还附加了装有外观为大扇形的马达的帧吊带.
They may take off from a tall cliff or snowy mountainside.
他们可能从高高的悬崖上或雪地的山坡上起飞.
Often, paragliders compete to see who can cover the greatest distance or make the best time along a specific airborne course.
通常,滑翔机会竞相寻找谁可以覆盖最远的距离,或者沿着特定的空中航道创造最佳时间.
They may take photos of reference points along the way to prove they passed a designated spot.
他们可以沿途取出参考点的照片来证明他们通过了指定地点.
Paragliders can stay in the air for hours at a time and travel great distances.
滑翔机一次可以在空中停留数小时,并远行.
