But, before we start, Id like to mention a few things your text doesnt go into. Its interesting to note

7、that insurance has existed in some form for a very long time. The earliest insurance policies were what we called bottomry contracts. They provided shipping protection for merchants as far back as 3000 B.C. In general, the contracts were often no more than verbal agreements. They granted loans to me

8、rchants with the understanding that if a particular shipment of goods was lost at sea, the loan didnt have to be repaid. Interest on the loans varied according to how risky it was to transport the goods. During periods of heavy piracy at sea, for example, the amount of interest and the cost of the p

9、olicy went up considerably. So, you can see how insurance helped encourage international trade. Even the most cautious merchants became willing to risk shipping their goods over long distances, not to mention in hazardous weather conditions when they had this kind of protection available. Generally

10、speaking, the basic form of an insurance Policy has been pretty much the same since the Middle Ages. There are four points that were salient then and remain paramount in all policies today. These were outlined in chapter six and will serve as the basis for the rest of todays discussion. Can anyone t

11、ell me what one of those points might be?我希望你们已经阅读了有关保险的指定章节，所以你们对今天的讨论是有准备的。但是，在我们开始前，我想说你们课文里没有的几件事。有趣的是，保险已经以某些形式存在很久了。最开始的保险政策是冒险借贷契约。公元前3000年，它们提供商人海运保护。一般来说，契约通常是口头协议。他们授予商人们贷款，如果装运物品在海里丢失了，贷款就不用还了。贷款利息的不同取决于运输货物的风险。在海盗行为严重的时期，比如，利息总额和政策的价格上升了很多。所以，你可以看到保险是如何帮助促进国际贸易的。即使是最谨慎的商人也开始想去承担长距离运输货物的风

12、险，更不用说当恶劣的天气条件时他们有这种保护。一般来说，保险政策的基本形式从中世纪起就几乎一样。在所有政策里，有四个方面是显著和重要的。这些在第六章中都概括了并且会是今天其余的讨论。有人能告诉我其中的一个方面是什么吗？3Located at the NASA Research Center in Iowa is a 5,000-gallon vat of water, and inside the tank is an underwater treadmill designed by Dava Newman, an aerospace engineer. For four years Newm

13、an observed scuba divers as they simulated walking on the Moon and on Mars on her underwater moving belt. She wanted to discover how the gravity of the Moon and of Mars would affect human movement. To do this, Newman attached weights to the divers and then lowered them into the tank and onto the tre

14、admill. These weights were carefully adjusted so that the divers could experience underwater the gravity of the Moon and of Mars as they walked on the treadmill. Newman concluded that walking on Mars will probably be easier than walking on the Moon. The Moon has less gravity than Mars does, so at lu

15、nar gravity, the divers struggled to keep their balance and walked awkwardly. But at Martian gravity, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmill, the divers took longer, graceful stri

16、des until they comfortably settled into an even quicker pace. Newman also noted that at Martian gravity, the divers needed less oxygen. The data Newman collected will help in the future design of Martian space suits. Compared to lunar space suits, Martian space suits will require smaller air tanks;

17、and, to allow for freer movement, the elbow and knee areas of the space suits will also be altered.NASA的调查中心在IOWA有一个可容5000加仑水的大容器，内部有一个由航空宇宙工程师Dava Newman设计的水下踏车。四年来，Newman一直观察潜水者在她的水下传送带上的模仿在月球和火星上的行走。她想知道月球和火星的重力是如何影响人类的活动的。为了做到这些，Newman给潜水者加了一些重量，然后把他们放入水中，放到脚踏车上。这些重量是谨慎调整过的，因此。潜水者在脚踏车上时可以感受到月球或火

18、星上的重力作用。Newman推断在火星上的行走易于在月球上的行走，月球的重力小于火星，所以在月球重力的作用下，潜水者要努力保持平衡并且走路更笨拙一些。在火星的重力作用下，潜水者有更多的牵引力和稳定性，并且可以轻松达到1.5英里/小时的步速。随着Newman逐渐给脚踏车加速，潜水者步幅更大，动作更优美，直到他们达到一个更快步速。Newman也注意到在火星重力作用下，潜水者需要的氧气更少。Newman收集到的资料将有助于未来火星空间服的设计。与月球服相比，火星服将有更小的空气罐，而且，为了保证更自由的行动，火星服的肘部与膝部的空间也会被改变。4Welcome to Everglades Natio

19、nal Park. The Everglades is a watery plain covered with saw grass thats home to numerous species of plants and wildlife. At one and a half million acres, its too big to see it all today, but this tour will offer you a good sampling. Our tour bus will stop first at Taylor Slough. This is a good place

20、 to start because its home to many of the plants and animals typically associated with the Everglades. Youll see many exotic birds and, of course, our world famous alligators. Dont worry, theres a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe dist

21、ance. The boardwalk is high enough to give you a great view of the saw grass prairie. From there well head to some other marshy and even jungle like areas that feature wonderful tropical plant life. For those of you whod like a closer view of the saw grass prairie, you might consider renting a canoe

22、 sometime during your visit here. However, dont do this unless you have a very good sense of direction and can negotiate your way through tall grass. Wed hate to have to come looking for you. You have the good fortune of being here in the winterthe best time of year to visit. During the spring and s

23、ummer, the mosquitoes will just about eat you alive! Right now theyre not so bothersome, but youll still want to use an insect repellent.欢迎来到大沼泽地国家公园。沼泽地是一个被克拉莎草覆盖的潮湿的平原并且是很多野生物种的家园。今天看完全部的150万英亩太多了，但是这个旅行会给你提供一个很好的采样。我们的旅行公共汽车的第一站是Taylor Slough。这是一个好地方因为这是很多与沼泽地相关的动物和植物的家。你可以看到很多异国的鸟，当然，还有世界闻名的短吻鳄。

24、不用担心，这里有一个在沼泽地上方的小道，所以你可以从一个安全的距离看到底下在水里的动物。这个小道也是足够高的让你看到克拉莎草大草原。从那里我们会前往其他的有着奇妙的热带植物，如同沼泽般和丛林般的地方。对于你们中那些想近距离观察克拉莎草大草原的人，在旅游途中，你可以考虑借一个独木舟。但是，除非你有很好的方向感并且可以顺利通过高大的草丛，不然不要做。我们痛恨去找你。你们有着很好的运气在冬季来到这里旅游的最佳季节。在春天和夏天，蚊子会活活把你吃掉。现在它们并不是很麻烦，但你还是会需要一个驱虫剂的。5Thank you. Its great to see so many of you interest

25、ed in this series on Survival in Outer Space. Please excuse the cameras; were being videotaped for the local TV stations. Tonight Im going to talk about the most basic aspect of survivalthe space suit. When most of you imagine an astronaut, thats probably the first thing that comes to mind, right? W

26、ell, without space suits, it would not be possible for us to survive in space. For example, outer space is a vacuumtheres no gravity or air pressure; without protection, a body would explode. Whats more, wed cook in the sun or freeze in the shade with temperatures ranging from a toasty 300 degrees a

27、bove to a cool 300 degrees below zero Fahrenheit. The space suit that NASA has developed is truly a marvel. This photo enlargement here is a life-size image of an actual space suit worn by astronauts on the last space shuttle mission. This part is the torso. Its made of seven extremely durable layer

28、s. This thick insulation protects against temperature extremes and radiation. Next is what they call a bladder of oxygen thats an inflatable sac, filled with oxygen, to simulate atmospheric pressure. This bladder presses against the body with the same force as the Earths atmosphere at sea level. The

29、 innermost layers provide liquid cooling and ventilation. Despite all the layers, the suit is flexible, allowing free movement so we can work. Another really sophisticated part of the space suit is the helmet. I brought one along to show you. Can I have a volunteer come and demonstrate?谢谢。看到你们这么多人都对

30、“外太空生存”感兴趣真好。请不要介意摄像机，我们在给当地的电视台录像。今晚我要讲一讲在外太空生存的最基本的方面太空衣。当你们大部分人想象到一个宇航员时，太空衣是最先在脑海中出现的，对不对？没有太空衣，我们就不可能在外太空生存。比如说，外太空就像一个真空那里没有重力或者空气压力。没有保护，身体会爆炸。而且，在温度从暖烘烘的300华氏度到冰冷的零下300华氏度的变化下，我们会在太阳里被烤熟或者在背阴处冻结。NASA研制的太空服是一个真正的十分灵巧的东西。这个放大的照片是一个和实物一样大小的图像，反映的是在上一次航天飞机的任务中，宇航员穿着真正的太空衣。这个部分是身体躯干。它是由7个非常耐用的层制作

31、的。粗的绝缘材料保护温度末端和辐射。下一个是他们叫做氧气“囊”的充气囊。它里面充满了氧气，模仿大气压力。这个囊对身体的压力和地球大气层对海平线的压力一样。最里面的层提供液体冷却和通风。尽管有这些层，太空衣很灵活，允许自由的运动，所以我们可以工作。另一个太空衣很复杂的部分是头盔。我带了一个来给你们看。有没有志愿者想上来展示一下吗？6Good evening. My name is Pam Jones, and on behalf of the Modern Dance club, Id like to welcome you to tonights program. The club is pl

32、eased to present the TV version of The Catherine Wheel, Twyla Tharps rock ballet. This video version of the ballet has been even more successful with audiences than the original theater production. It includes some animation, slow motion, and stop-action freezes that really help the audience understand the dance. The title of the piece refers to Saint Catherine, who died on a wheel in 307 A.D. Nowadays, a Catherine wheel is also a kind of firework. It looks something like a pinwheel. Anyway, the dance is certainly full of fireworks! Youll see how Twyla Tharp explores one familys atte
