Since we value life above other things, the greatest risk for most people is the risk of death. Yet life itself, to the best of our knowledge, is ultimately limited. The key word here is “ultimately”. Since we hope to live a lot longer, we easily overlook the routine and long-range risks associated with being human, and concentrate instead on other sorts of risks. We rarely think about the chances of death, disability, or disaster, or try to predict the times of their occurrence. Walking across the street in many cities is more dangerous than riding an airplane across an ocean, but many people give no thought to the former and have great fear of the latter. People eagerly do dangerous things for recreation that they would rarely do at work, such as scaling a steep mountain or skiing rapidly down it. Young people are especially willing to take foolish chances for the sheer joy of doing so, or because they discount the probability of adverse outcomes. Yet they should probably be much more careful than their elders, since they have longer life expectancies remaining and thus have more at stake.Other things we value include health, safety, money, property, relationships and happiness. There are risks attached to the loss of any of these. Hypochondriacs exaggerate the risks of ill health or injury. Ironically the precautions taken to promote health and safety may add to a hypochondriacs perception of the risks involved. A wise investor takes calculated risks with money, and tries to choose reasonable risks over unreasonable ones. A compulsive gambler, on the other hand, is so addicted to risk that there is little thought of the loss that inevitably follows from gambling indefinitely against the odds. So risk itself may at times be perceived as a reward.Optimists and pessimists have opposite attitudes toward risk. Extreme optimists always expect the best. Therefore they try to maximize gain. More cautious optimists may try to maximize the minimum gain. Extreme pessimists always expect the worst. Therefore they come to expect the maximum loss. More moderate pessimists may try to maximize the minimum loss. The science of cost-benefit analysis studies these and other strategies for managing risk. So does actuarial science (保险计算科学), with special emphasis on the risks of death, injury, or illness.One way to manage risk in ordinary life is through rational planning. By considering alternatives and balancing the greatest or most likely risks against the greatest or most likely rewards, we can often make better decisions and give greater consideration to long-term outcomes. By always having a contingency plan in case our main plan fails, we can usually avoid catastrophes. But planning takes effort, and we must balance this effort against the pleasure of doing things spontaneously because they are not very important or not very risky, and plan other things carefully because they are very important or very risky.

Thats natural.2. Which activity is riskier?STEP ONEThe following is a list of the activities from the riskiest to the safest:rock climbing skydiving driving a motorcycle being a 65-year-old man skiing flying in an airplane driving a car working on a farm STEP THREEI prefer to do rock-climbing. I know its a risky sport but I really want to challenge myself and see how I can use my muscles and brain to do a tough job. You may ask why I like this risky sport while there are so many safer ones to test my strength and determination. I was born in a mountain area and Ive been enjoying mountain climbing since my childhood. I always feel excited while climbing a mountain, and rock-climbing is even more exciting. Its true rock-climbing is full of dangers, but life itself is full of dangers too. With modern equipment and our brains, we can prevent serious accidents and minor injuries wont hurt us too much. I dont think I would like any of the activities listed. Actually I dont like sports. As far back as I can recall, my childhood was spent in hospital. In other words, I was in poor health for a long time. When other children in the neighborhood began their training in sports, I had to go to hospital and take medicine to survive. In that case, I wasnt allowed to play outdoors most of the time. In addition to my physical weakness, Im cautious by nature. I dont like to take any risks in my life. Anyway, Im an excellent chess player. My father taught me how to play chess and bought several books about chess to improve my skill. So chess is something I enjoy most. 3. Why Would People Like to Take Risks?Sample:I am really impressed by these quotes. They tell us that life is full of risks. As Ali put it, he who is not courageous enough to take risks will accomplish nothing in life. So taking risks is an essential part of growth and progress. If we look at some famous people we know, obviously they are all good risk takers. In addition to making achievements, some people take risks to enjoy a new experience and to challenge themselves. They want to look like a courageous guy or a strong person. Taking risks will make them feel more confident and competent. They also want to enjoy the excitement in risk taking because their lives are otherwise too peaceful and comfortable.Part Two READING-CENTERED ACTIVITIESIn-Class ReadingPre-ReadingSampleThe three riskiest things I do in a normal day: ride my bicycle in heavy traffic; run down stairs; do scientific experiments.Passage ReadingWords, Phrases and Grammatical Points1. risk关于risk的词组有很多：at risk 处于危险之中e.g. I) The disease is spreading, and all children under five are at risk. II) Heart disease can be avoided if people at risk take medical advice.at the risk of 冒的危险e.g. I) He saved my life at the risk of losing his own. II) At the risk of offending you, I must tell you that I disapprove of your behavior.run the risk of 冒的危险e.g. I) I dont want to run the risk of meeting George.

Group Discussion1) I think airplanes are safer.2) Perhaps because airplane crashes are almost always fatal. If you are in an airplane crash, you will die most probably, but you might not be killed in a car accident. Even though fewer people die in air crash than in car accidents, people feel far less secure in the air than on the ground. We are still more used to cars than airplanes.Vocabulary Practice1. 1) sensiblesensible: having or showing good sense; reasonablesensitive: easily hurt, upset, or offended by things that people say2) relativerelevant: directly connected with the subject or problem being discussed or consideredrelative: considered in relation or proportion to somebody/something else; comparative3) mechanismmachine: 机器mechanism: a structure of working parts functioning together to produce an effect4) requiresrequire: need somethingrequest: ask for something politely or formally5) eliminatereduce: make something smaller in size, number, degree, price, etc.eliminate: completely get rid of something that is unnecessary or unwanted6) crashcrash: a breaking to pieces especially by or as if by collisioncollision: an accident in which two or more people or vehicles hit each other while moving in different directions2.1) character 2) end up 3) Rarely 4) casual 5) risky 6) all manner of 7) inform 8) sensible 9) definitively3. 1) On the strength of 2) all manner of 3) feed on 4) reduceto 5) end up 6) associated with 7) focus on 8) turned to 9) participate in 10) involved in课外阅读参考译文Passage I健康威胁1 民意调查一再告诉我们，美国人最为担心的就是他们的健康，其次才是环境问题。这是完全可以理解的，因为身体健康显然比生病要好。美国人现在对健康如此关注，是有点令人吃惊，因为他们目前比以往任何时候都要健康得多。许多曾令人恐惧的疾病现在或者已经彻底根除，或者已得到控制。尽管艾滋病是个显著的例外，但是现在几乎没有什么新的能置许多人于死地的疾病出现，以取代那些已被根除的疾病。2 然而，健康以及对健康的各种威胁，仍然是人们永久关注的问题。毕竟，如果目前的趋势无法制止的话，我们中将有不止一半（57）的人将死于心脏病或是癌症。3 将威胁健康的危险，特别是致命的危险，进行比较时，有一个主要的问题，就是这些危险的紧迫性有很大差异。例如艾滋病，如果你染上的话，很可能几年后就死亡。然而，由吸烟或辐射诱发的癌症，也许要经过20至30年的时间其灾难性的后果才会出现。因此，在对健康的各种危险做出选择时，务必要考虑进行冒险与承受其后果之间的时间间隔。4 那些一心要“今朝有酒今朝醉”的人们，往往对潜伏期较长的危害不放在心上。尽管这是一种目光短浅的行为，但不理会滞后期长的危险，重视近期危险还是有道理的。毕竟，如果我们真的面临选择，是去做今天就可能使我们丧命的事，还是去做20年后才可能使我们丧命的事，我们往往会两害相比取其轻。5 对待这类问题有种常用的计算方法，就是考虑可能少活的年数（YPLL）。其意思是，对一个25岁的人来说，去做一件使自己五年后丧生的事要比做一件40年后丧生的事“代价高昂”得多。二者同样都具有危险因素即最终因从事某事而导致死亡的可能性相同但是，会马上引起伤害的危险，要比一个很长时间不需付出代价的危险要昂贵得多。在第一种情形下，他的正常寿命减少了约45年，而在第二种情形下，减少了约5年。以这种角度看问题必然会对威胁健康的许多因素进行重新评估。例如，心脏病是夺去美国人性命的头号杀手，远远超过癌症或中风。然而，老年人患心脏病的比例大大超出了年轻人。相比之下，癌症的死亡人数虽然要少于心脏病的死亡人数，但患癌症的人群比较年轻。所以，尽管心脏病死亡率要大，但癌症损失的YPLL要比心脏病多。具体来讲，与心脏病相比，癌症让人大约多损失了25的YPLL（如果我们将YPLL定义为65岁以前寿命缩短的年头）。6 YPLL这一概念，尽管人们对它还有争议，却对保健经济学有着重要影响。人们经常争辩说，用于医学研究攻克疾病的资金应该按每种疾病死亡人数的多少来分配。因此，一些人士抨击将大量资金用于艾滋病研究。他们认为与其它致命的疾病如心脏病和癌症相比，艾滋病得到了不成比例的高额资助。该批评没有考虑到这样一个事实：由于艾滋病的主要受害者为二三十岁的年轻人，尽管每年只造成20,000人死亡该数字本身也不小了但是艾滋病引起的YPLL要大得多，远比简单的死亡人数更值得我们重视。换句话说，找到治疗艾滋病的方法，将可能增加每位潜在的艾滋病患者25至30年的寿命。找到治疗心脏病的方法，虽然可能拯救更多人的生命，但对每位受害者来说只能增加平均5到10年的寿命。7 对一种危险的严重程度的估算会有差异，这要看我们是关注它所引起的死亡人数还是它所导致的YPLL的多少。有些差异很令人吃惊。比如，如果我们只算引起的死亡人数的话，与癌症和心脏病相比，意外死亡就显得无足轻重。然而，一旦我们关注所损失的YPLL，意外事故却赫然位居美国杀手榜的榜首。这些数据显示，我们不仅要探究危险程度的大小，而且要探究危险什么时候要我们付出代价。在其它因素都相等的情况下，危险所导致的损害或死亡来得越快，人们就越应该回避这种危险。Passage II寻求刺激者1 “简单的冒险”已成为一种新兴的假日娱乐项目。如今在西方每逢节假日，游客都有很多旅游胜地和娱乐项目可以选择。但同时大多数旅行代理商都认为传统的海滩度假已不再时髦，越来越多的人在寻找新的娱乐项目。2 英国林顿库柏旅行社的彼得伊文思解释说：“我们绝大多数顾客都喜欢冒险性的活动。沙滩度假已经是过去的事情了，人们对此已不再觉得希奇了。我们目前正在努力做的就是开发新颖而又刺激的活动项目。”3 像彼得伊文思这样的旅行代理商提供的活动内容丰富，从漂流非洲赞比西河，直到攀登世界最高峰。尽管这样，仍有一些游客还觉得不够刺激。于是他们转向了所谓的“极限运动”，诸如“空中冲浪”（与水上冲浪相似，但在自由落体跳伞过程中进行）、“极限自由滑雪”（从悬崖顶滑下来）。4 这些运动主要的魅力在于它们有伤亡的风险。布伦丹柯纳是一位驻华盛顿的记者，一直关注极限运动的兴起。他认为这种运动确实存在风险。风险的严重程度各不相同，可能是市内危险运动如穿直立式旱冰鞋溜冰引起的手腕骨折等创伤，也可能严重到丧失生命那些热衷于进行低空跳伞这类高风险运动的人会有这种危险。5 柯纳介绍说：“低空跳伞是指乘降落伞从固定的物体，比如摩天大楼，或河流的峡谷顶上往下跳。我看到过一些关于这项运动的数据，大约每700次低空跳伞中就有一次是致命的。相比之下，传统的跳伞运动每90,000次才有一次是致命的。”6 很多人还没有做好充分准备就去尝试高风险运动，这使得情况更糟糕。例如，攀登高山成了近几年越来越流行的一项运动，可是很多人似乎并不了解其中的风险。去年夏天，欧洲最高的阿尔卑斯山脉有90多个登山者遇难，其中有一天就死了12人。今年夏天，攀登事故的死亡人数估计仍会居高不下。这并不是因为山脉本身变得越来越危险了，而是由于更多的攀登者没有足够的经验和必要的设备。比如去年就有报道说，有登山者只穿着短裤和网球鞋就试图徒步穿过冰河，在他们当中只有十分之一的人配有合格的登山向导。7 那么，为什么有越来越多的人想冒险和体验危险呢？部分原因是近年来冒险的机会急剧增加。现在的旅游公司几乎可以把游客带到世界上任何地方，从珠穆朗玛峰到南极。在国内，公司排着队向人们提供体验危险的机会。例如，现在在世界各地的城市里，你都会看到一种叫蹦极跳的运动。人们只要用一根有弹性的绳索拴住脚腕，就可以把自己从高高的塔顶抛下去。8 杰罗姆斯梅尔是英国新近一家极限运动杂志的编辑，他认为这些运动虽然危险性高，却能帮助人们拓展视野。“越来越多的人愿意进行这项活动，是因为这是体验人生的捷径，”他说。“他们付了钱就能体验到那种因分泌肾上腺素而产生的兴奋，这是一般人在正常情况下无法体验的。而且我认为极限运动还可以使人们逃避朝九晚五的生活方式,而过着这种平淡生活的人不在少数。”9 布伦丹 柯纳同意这种说法。他认为极限运动在美国之所以盛行是人们对自己过于安逸舒适的生活的反动。10 “我们生活在人类历史上法律诉讼最多的时代。为了防止有人受到起诉，金属攀登架和秋千被搬出了孩子们的操场。如今的美国生活充满了各种各样的规章制度，以保证尽可能地安全。”11 柯纳认为过于强调安全性是与美国的冒险精神相违背的。美国自早期的拓荒者开始就崇尚冒险，这种精神一直可以在电影里看到。“看看我们的好莱坞电影，里面有各种各样的动作明星。当人们环视周围枯燥的郊区环境时，不禁要问哪儿有适合我的刺激和惊险啊？。”12 而且心理学家们也赞同此观点。他们相信人们的生活中需要一点刺激。英国设菲尔德大学心理学教授巴里 冈特解释道：13 “从根本上说，追求新鲜事物是人的基本需求，人们时不时地会想要冒一点险，以便在应对周围的环境时感到更得心应手。”14 寻找挑战以证明自己勇气和胆量的欲望似乎显示了典型的阳刚之气，但是，虽然极限运动的主要倡导者和支持者是年轻小伙子，该运动也吸引了女性。15 不仅仅是旅行社一直在充分利用人们对冒险运动的向往。软饮料的生产商百事公司也把极限运动的理念，结合到了最近的广告中，宣传的对象就是年轻人。百事公司英国市场的经理西蒙 洛登认为利用危险体育做广告能在年轻人中引起共鸣。16 “充分享受生活，享受今天，是Pepsi Max饮料的全部理念。极限运动真正实现了这个愿望。不管年轻人是否真的从事这项运动，但至少能够使他们心生向往，说：是的，我愿意这样做。况且，从极限运动中我们享受到了怎样的飘飘欲仙的感觉啊那是真正的飘飘欲仙！”Part Three FURTHER DEVELOPMENT1.

Leaving two young children alone in the woods is unwisesomething unexpected could happen to them. And if you drown, they might never be found.Possibility 2: Letting the 14-year-old boy go alone to try to find the right path is very foolish. He could fall and hurt himself or he could get lost and get very frightened.Possibility 3: Not moving and spending the night in the forest is also risky. The temperature might drop, you might be very cold and you still might not be found the next day.All three possibilities are full of risks. But, if you are a very good swimmer and you are fairly confident that there are houses on the other side of the lake, then Possibility 1 would be a fairly safe choice. If you are quite confident that people might start looking for you in daylight, then Possibility 3 might be a safe choice. If you huddle close together, you will be able to keep warm. Getting sleep or rest will help conserve your energy.3. Personal SafetySamples1) Ways of describing numbers: Motor vehicle accidents account for the largest percentage (59.0%) of all accidental deaths, followed by falls, which make up almost 15% of the accidental deaths. Only about 2.5% of all accidental deaths are caused by firearms.2) Suggested ways of preventing accidents: reduce the speed limit; make less powerful cars; never ride a motorcycle without wearing a helmet and protective gear;never go swimming alone and be careful not to swim in dangerous areas; wear a life jacket if you are not a good swimmer;constantly check electric wires and replace old ones;keep poisons out of the reach of children; ban all firearms; wear a safety belt while driving.4. Staging a Talk ShowSample Host: Good Evening, everybody. Welcome to our Talk Show Program this week. Tonight we have three guest speakers from XXX University to discuss the rise of extreme sports and their popularity among college students. Now risky sports like bungee jumping, skiing, base jumping, rock climbing, mountaineering are no longer new to them. Participating in these sports is a growing trend. As we know, some students get injured and some have even lost their lives. So many people begin to ask whether it is worthwhile for college students to take these risks. We
