The Reverse Bungee  反向高空彈跳,一起衝上天吧!

  The mechanics of bungee jumping are well known. The jumper, wearing a harness attached to a long, elastic cable, leaps from a platform high above the ground. As the jumper plunges _(1)_, his or her fall is slowed by the springy bungee cable, which causes the jumper to bounce up and down like a yo-yo before being lowered gently to the ground.
  A reverse bungee operates on the same principle, but turns it on its head. _(2)_ the bungee jumper starts high, the reverse bungee riders start on a ground-level platform. The riders are strapped into a capsule _(3)_ by elastic cables between two telescopic towers. The capsule is held to the platform by an electromagnetic switch, and the riders lie back and watch the towers _(4)_ higher and higher, which stretches the bungee cords.
  When the towers have reached their _(5)_ heights and the cables are at their tightest, the ride operator flips a switch to release the capsule. Like a rocket being launched, the riders and capsule are hurled skyward _(6)_ speeds close to 200km/h before being stopped by the twin bungee cords. Once the trip ends, gravity _(7)_ and the riders fall back down to Earth and are stopped again by the elastic cords before hitting the ground. After a minute or two of bouncing, the riders are lowered towards the ground, shaken, but often wanting another ride.
