dangerous sports activities
around the world more and more people are taking part in dangerous sports activities. of course,there have always been people who have looked for adventure those who have climbed unknown parts of the world or sailed in small boats across the greatest oceans. now,however, there are people who seek an immediate thrill, a risky activity, which may only last a few minutes or even seconds.
bungee jumping is a good example of such an activity.you jump from a high place 200 meters above the ground with an elastic rope tied to your feet. you fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. it is estimated that two million people around the world have now tried bungee jumping.
why do people take part in such activities as these?some psychologists suggest that it is because life in modern societies has become safe and boring. in ancient times,people's lives were constantly under threat. they had to go out and hunt for food. diseases could not easily be cured, and there was a continuous battle for survival.
nowadays, according to many people, life offers little excitement. they live and work in comparatively safe environments;they buy food in shops;there are doctors and hospitals to look after them if they become iii. it is necessary for some of these people to seek danger in activities such as bungee jumping.
危险运动
世界上正有越来越多的人加入到危险运动中来。 当然，世上一直都有寻找刺激的人 他们攀越不为人知的高山，驾艇横跨大洋。但是如今，人们开始寻找转瞬即来的刺激，有时这些冒险的活动仅能持续几分钟，甚至几秒钟。
蹦极就是这种活动的一个很好的例子。人从距离地面200米的高处蹦下，以高达150公里的时速下落.脚上捆着的弹性绳保护着你以免撞上地面。据估计世界上已有两百万人体验过蹦极跳了。
为什么人们会投入到这些运动中来呢?一些心理学家指出，这是因为现代社会的生活过于安全而乏味。而在古代，由于人们的生活常常处在各式各样的危险之下，人们不得不出去打猎以获取食物。一旦生病就很难治疗，人们为了生存而不懈地斗争。
对于很多人来说，现在的生活太过死气沉沉。 大家生活、工作在相当安全的环境中。他们在商店购物；一旦生病，医生和医院会为他们提供很好的照顾。在蹦极这样的活动中寻找刺激成为了一些人必然的选择。
