阅读理解 　　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 oceans. Now, however, there are people who seek an immediate thrill from a dangerous sport 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 hot－air balloon) 200 meters above the ground with an elastic rope tied to your ankles. You fall at up to 150 kilometers an hour until the rope stops from hitting the ground. It is estimated that two million people around the world have tried bungee jumping. Other activities which most people would say are as dangerous as bungee jumping include jumping from tall buildings and diving into the sea from the top of high cliff. 　　Why do people take part in such activities as these?Some psychologists suggest that it is because life in modern society has become safe and boring. Not very long ago, people's lives were usually under threat. They had to go out and hunt for food; diseases could not easily be cured, and life was a continuous battle for survival. 　　Today, according to many people, life offers little excitement. They live and work in comparatively safe environments; they buy food in shops; and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to seek excitement in activities such as bungee jumping. 1．A suitable title for the text is ________. [　　] A．Dangerous sports: What and Why?
