     More and more people around the world are joining in dangerous sports. Some people climbed the

highest mountains; some traveled into unknown parts of the world; some sailed small boats across the

largest sea. Now some people begin to look for new excitement.

     Bungee jumping (蹦极) and motorcycle racing  (摩托车赛) are  quite dangerous sports. Bungee

jumping only lasts a few minutes or even seconds. You jump from a high place, 200 meters above the

ground, and there is a  rubber  band (橡胶带子) tied to your legs. When you jump down, the rubber

band pulls you up. About 2,000,000 people around the world have tried bungee jumping.

     Why do people join in these dangerous sports? Some scientists say that it is because modern life

has become safe and it is not interesting. In the past, people lived in danger. They had to go out and

look for food, and life was like a fight but was interesting.

     Many people think that there is little excitement in life. They live and work in safe places, buy food

in shops, and there are doctors and hospitals to look after them if they become ill.
