Bungee jumping ( 蹦极 ) and motorcycle racing 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 ( 带子 ) tied to your legs. 【小题2】
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. 【小题3】 They had to go out and look for food, and life was like a fight but was interesting.
【小题4】 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.

【小题5】Which of the following is WRONG?A．People like to join in dangerous sports because they need excitement.B．Traveling into unknown parts of the world is not a dangerous sport.C．In bungee jumping, you jump down with a rubber band tied to your legs.D．In the past, people lived in danger because the living condition was poor.B

(答案→)B 解析：这篇短文说的是越来越多的人愿意去从事一些比较危险的运动，如爬最高的山，去世界上未知的地方旅行、划船过最大的海等。还特别提到了很受欢迎的一种运动---蹦极。作者分析了这种现象可能的原因。【小题1】句意：现在人们开始寻找新的刺激。根据这段内容可知，以前人们从事一些像爬山、旅行、航海这样的冒险运动，现在又开始寻找新刺激了。故选B。【小题2】句意：当你跳下来的时候，这个带子会把你拉上来。这里说的是蹦极这项运动，由上句there is a rubber band ( 带子 ) tied to your legs，结合文意可知选D。【小题3】句意：过去人们生活在危险中。这里是作者在分析这种现象的原因，过去人们的生活就像一场战斗，但却很刺激，现在的人们缺少了这种刺激，所以才通过参加一些危险的运动来寻找刺激。故选A。【小题4】句意：很多人觉得生活中令人感到刺激的事情太少了。根据这段文意可知，现在的人们生活的很安逸，工作、生活的地方很安全、商店里有食物、生病时医院了有医生，所以他们觉得刺激的事太少了。故选C。【小题5】根据文章第一段some traveled into unknown parts of the world可知，去世界上未知的地方旅行是一种危险的运动。故选B。
