　　Bungee Jumping

　　Around the world more and more people are taking part in dangerous sports and activities.Of course，there have always been people who have looked for adventure-those who have climbed the highest mountain，explored unknown parts of the world or sailed in small boats across the greatest ocean.Now，however，there are people who seek an immediate thrill from a risky activity which may only last a few minutes or even seconds.

　　I would consider bungee jumping to be a good example of such an activity.You jump from a high place(perhaps a bridge or a hot­air balloon)200 meters above the ground with an elastic rope tied to

　　 your ankles.You fall at up to 150 kilometers an hour.It is estimated that 2 million people around the world have now tried bungee jumping.Other activities which most people would say are as risky as bungee jumping involve jumping from tall buildings and diving into the sea from the top of high cliffs.
