     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 (冒险) and those who have

climbed the highest mountains or explored unknown parts of the world. Now, however, there are

people who look for a quick pleasure from a dangerous activity, which may only last a few minutes or

even seconds.

     I think bungee jumping is a good example of such an activity. You jump from a high place (maybe a

bridge or a hot-air balloon) 200 meters above the ground with an elastic rope (弹力绳) to your ankles (踝). You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is said

that 2, 000, 000 people around the world have now tried bungee jumping. Most people think that other

activities, such as jumping from the tall buildings and diving into the sea from the top of high rocks are as

dangerous as bungee jumping.

     Why do people take part in such activities? Some scientists think it is because life in modern

societies has become safe and boring. Now life has little excitement. They buy food in shops and there

are doctors and hospitals to look after them if they are ill. The answer for some of these people is to

look for danger in activities as bungee jumping.
