Around the world more and more people are 1 dangerous sports and activities. Of course there have always been people who have 2 adventure—those who have climbed the 3 mountains, explored unknown parts of the world or 4 in small boats across the greatest oceans. Now, however, there are people who look for an immediate pleasure from a 5 activity which may only last a few minutes or even 6.
I would consider bungee jumping to be a good example of such an activity. You 7 from a high place about 200 meters above the ground with an elastic rope 8 to your ankles. You 9 at up to 150 kilometers an hour until the rope stops you from 10 the ground. It is said that 2 million people around the world have now 11 bungee jumping. Other activities, 12 most people would say are as dangerous as bungee jumping, 13 jumping from tall buildings and 14 into the sea from the top of high rocks.
Why do people take part in such activities as these? Some psychologists(心理学家) suggest that it is because life in 15 societies has become safe and boring. Not very long ago, people’s lives were constantly under 16. They had to go out and hunt for 17, and life was a continuous battle for survival.
Nowadays, according to many people, life offers 18 excitement. They live and work in relatively safe condition; they buy food in shops; and there are doctors and hospitals to 19 them if they become ill. The answer for some of these people is to 20 danger in activities such as bungee jumping.

答案：
(答案→)1-5BCBAD 6-10BABCD 11-15ABBCB 16-20CBBDA
解析：
1. B。从本段后面所举的例子来看，此处说的是越来越多的人正参加各种危险的运动。“从事”应说 go in for，故 C 不对。
2. C。上句说越来越多的人参加各种危险的运动，从 Of course 可推测此处说“也不乏有人参加冒险”。
3. B。从破折号来看，下文是通过例子来说明有人参加冒险活动。根据所举的几个例子来看，此处选 highest 才能与“冒险”这个主题相吻合，并与 explored unknown parts of the world 等语意一致。
4. A。从下面的 in small boats across the greatest oceans 看此处说的应是“乘船在大洋上航行”，故选用 sail。
5. D。此句中的however说明后面提到的运动与前面提到的不同，这里说的是有些人从持续时间很短的一项运动中得到瞬间快乐。从下文来看，作者认为 bungee 就属于这种运动，也是很危险的，故用 dangerous。
6. B。从前面的 …who look for an immediate pleasure 及 which may only last a few minutes or even… 等可推测，此处说的是这项运动持续时间短，显然 hours, days 和 years 不合语境。
7. A。从这一段开始介绍 bungee 运动。根据下文介绍的 from a high place about 200 meters above the ground 来看，该运动是从离地面大约 200米处望下跳。
8. B。在往下跳时，运动员的脚踝要系在绳子上，也就是要把绳子栓在脚踝上，所以用 tied。
9. C。从高处跳起，然后坠落下去，所以用 fall。
10. D。此处介绍的是系绳子的目的——不让你撞到地上。
11. A。根据下文看，世界上有很多人都已经尝试过蹦极这项运动。
12. B。此处应用 which 引导非限制性定语从句，which 指代前面提到的 other activities。
13. B。前面提到的 bungee 是从高处往地面跳，这里具体说从何处往下跳：一是从大楼往下跳，二是从高的岩石上往海面跳。故此处应用 include。
14. C。从下文的 into the sea 可看出是“跳水”，故用 diving。
15. B。从上下文来看，本文所介绍的活动是新兴的一项运动，也就是现代人所从事的活动，由此可推断此处选 modern，既说明“现代社会人们的生活很安全、枯燥”，故许多人从事这项运动来寻找刺激。
16. C。前面说现在人们生活舒适而乏味，与此相对照，此处说的是过去人们外出狩猎，生活就是持续的生存斗争，故此处应选 danger。
17. B。从 and life was a continuous battle for survival 等来看，此处说的是人们外出“猎取食物”，故用 food。
18. B。从后文可知“现在人们生活、工作在相对安全的环境下”，与狩猎相比，现代人的生活少了刺激，所以也就少了欢乐，故用 little。
19. D。从 if they become ill 知，此处说的是“当生病时有大夫等来照看他们”，故用 look after。
20. A。此句是总结全文的话。从整篇文章来看，此处说的是人们在刺激的运动中寻找危险。
