1、第一篇 Captain Cook Arrow Legend 库克船长弓箭的传说It was a great legend while it lasted，but DNA testing has (1) finally ended a two-century-old story of the Hawaiian arrow carved from the bone of British explorer Captain James Cook(2) who died in the Sandwich Islandsin 1779. “There is (3) noCook in the Austral

2、ian Museum，museum collection manager Jude Philip said not long ago in announcing the DNA evidence that the arrow was not made of CookS bone.But that will not stop the museum from continuing to display the arrow in its(4) exhibition，“Uncovered：Treasures of the Australian Museum,” which(5) does includ

3、e a feather cape presented to Cook by Hawaiian King Kalaniopuu in 1778. Cook was one of Britains great explorers and is credited with(6) discovering the“Great South Land，(7) now Australia, in 1 770.He was clubbed to death in the Sandwich Islands，now Hawaii。The 1egend of Cooks arrow began in 1824 (8)

4、 whenHawaiian King Kamehameha on his deathbed gave the arrow to William Adams，a London surgeon and relative of Cooks wife，saying it was made of Cooks bone after the fatal(9) fightwith islanders. In the 1890s the arrow was given to the Australian Museum and the legend continued (10) until it came fac

5、e=to-face with science. DNA testing by laboratories in Australia and New Zealand revealed the arrow was not made of Cooks bone but was more (11) likelymade of animal bone。said Philp. However, Cooks fans (12) refuse to give up hope that one Cook legend will prove true and that part of his remains wil

6、l still be uncovered.as they say there is evidence not a11 of Cooks body was (13) buried at sea in 1 779.“On this occasion technology has won，”said Cliff Thornton，president of the Captain Cook Society, in a (14) statement from Britain.“But I am (15) sure that one of these daysone of the Cook legends

7、 will prove to be true and it will happen one day. 第二篇 Avalanche and Its Safety雪崩和安全问题 An avalanche is a sudden and rapid flow of snow, often mixed with air and water, down a mountainside. Avalanches are (1) among the biggest dangers in the mountains for both life and property.All avalanches are cau

8、sed by an over-burden of material, typically snowpack, that is too massive and unstable for the slope (2) that supports it. Determining the critical load, the amount of over-burden which is (3)likely to cause an avalanche, (4) is a complex task involving the evaluation of a number of factors. Terrai

9、n slopes flatter than 25 degrees or steeper than 60 degrees typically have a low (5)risk of avalanche. Snow does not (6)gather significantly on steep slopes; also, snow does not (7)flow easily on flat slopes. Human-triggered avalanches have the greatest incidence when the snows angle of rest is (8)b

10、etween 35 and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees. The rule of thumb is: A slope that is (9) flat enough to hold snow but steep enough to ski has the potential to generate an avalanche, regardless of the angle. Additionally,

11、 avalanche risk increases with (10) use ; that is, the more a slope is disturbed by skiers, the more likely it is that an avalanche will occur. Due to the complexity of the subject, winter travelling in the backcountry is never 100% safe. Good avalanche safety is a continuous (11) process , includin

12、g route selection and examination of the snowpack, weather (12) conditions , and human factors. Several well-known good habits can also(13) reduce the risk. If local authorities issue avalanche risk reports, they should be considered and all warnings should be paid (14) attention to. Never follow in

13、 the tracks of others without your own evaluations; snow conditions are almost certain to have changed since they were made. Observe the terrain and note obvious avalanche paths where plants are （15）missing or damaged. Avoid traveling below others who might trigger an avalanche.第三篇Giant Structures巨型

14、建筑It is an impossible task to select the most amazing wonders of the modern world since every year more 1 wonderful constructions appear. Here are three giant structures which are worthy of our 2 admiration although they may have been surpassed by some more recent wonders.The Petronas Twin Towers1Th

15、e Petronas Towers were the tallest buildings in the world when they were completed in 1999. With a 3 height of 452 metres, the tall twin towers, like two thin pencils, dominate the city of Kuala Lumpur2. At the 41st floor, the towers are linked by a bridge, symbolizing a gateway to the city. The Ame

16、rican 4 architect Cesar Pelli designed the skyscrapers.Constructed of high-strength concrete, the building provides around l, 800 square metres of office space 5 on every floor. And it has a shopping centre and a concert hall at the base. Other 6 features of this impressive building include double-d

17、ecker lifts, and glass and steel sunshades.The Millau Bridge3The Millau Bridge was opened in 2004 in the Tarn Valley, in southern France. 7 At the time it was built, it was the worlds highest bridge, 8 reaching over 340m at the highest point. The bridge is described as one of the most amazingly beau

18、tiful bridges in the world. It was built to 9 relieve Millaus congestion problems. The congestion was then caused by traffic passing from Paris to Barcelona in Spain. The bridge was built to withstand the 10 most extreme seismic and climatic conditions. Besides, it is guaranteed for 120 years!The It

19、aipu Dam4 The Itaipu hydroelectric power plant is one of the largest constructions of its kind in the world. It consists of a series of dams across the River Parana5, 11 which forms a natural border betweenBrazil6 and Paraguay. Started in 1975 and taking 16 years to complete, the construction was ca

20、rried out as a joint project between the two 12 countries . The dam is well-known for both its electricity output and its size. In 1995 it produced 78% 0f Paraguays and 25% 0f Brazils 13 energy needs. In its construction, the 14 amount of iron and steel used was equivalent to over 300 Eiffel Towers8

21、. It is a 15 truly amazing wonder of engineering.第四篇 Animals “Sixth Sense” 动物的“第六感” A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, （1）however, seem to have escaped that terrible tsunami. Thi

22、s phenomenon adds weight to notions that I they possess a “sixth sense” for （2）disasters, experts said. Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean islands coast clearly （3）missed wild beasts, with no dead animals found. “No elephants

23、 are dead, not （4）even dead rabbit. I think animals can （5）sense disaster. They have a sixth sense. They know when things are happening.” H.D. Ratnayake, deputy director of Sri Lankas Wildlife Department, said about one month after the tsunami attack. The （6）waves washed floodwaters up to 2 miles in

24、land at Yala National Park in the ravaged southeast, Sri Lankas biggest wildlife （7）reserve and home to hundreds of wild elephants and several leopards. “There has been a lot of （8）apparent evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been p

25、roven,” said Matthew van Lierop an animal behavior（9）specialist at Johannesburg Zoo. “There have been no （10）specific studies because you cant really test it in a lab or field setting2,” he told Reuters. Other authorities concurred with this （11）assessment. “Wildlife seem to be able to pick up certa

26、in （12）phenomenon, especially birds there are many reports of birds detecting impending disasters,” said Clive Walker, who has written several books on African wildlife. Animals （13）certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal

27、 “sixth sense”-or （14）some other mythical power-is an enduring one3 which the evidence on Sri Lankas ravaged coast is likely to add to. The Romans saw owls （15）as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.第五篇 Si

28、nging Alarms Could Save the Blind 警报器救盲人If you cannot see, you may not be able to find your way out of a burning building - and that could be fatal. A company in Leeds could change all that （1）with directional sound alarms capable if guiding you to the exit.Sound Alert, a company （2）run by the Unive

29、rsity of Leeds, is installing the alarms in a residential home for （3）blind people in Sommerset and a resource centre for the blind in Cumbria.（4）The alarms produce a wide range of frequencies that enable the brain to determine where the （5）sound is coming from.Deborah Withington of Sound Alert says

30、 that the alarms use most of the frequencies that can be （6）heard by humans. “Its a burst of white noise （7）that people say sounds like static on the radio,”she says. “Its life-saving potential is great.”She conducted an experiment in which people were filmed by thermalimaging cameras trying to find

31、 their way out of a large （8）smoke-filled room. It （9）took them nearly four minutes to find the door （10）without a sound alarm, but only 15 seconds with one.Withington studies how the brain （11）processes sounds at the university. She says that the （12）source of a wide band of frequencies can be pinp

32、ointed more easily than the source of a narrow band. Alarms （13）based on the same concept have already been installed on emergency vehicles.The alarms will also include rising or falling frequencies to indicate whether people should go up （14）or down stairs. They were（15）developed with the aid of a

33、large grant from British Nuclear Fuels.库克船长弓箭的传说这本是个绝妙的传说，但DNA测试最终结束了这个长达两个世纪之久的古老故事。传说是关于一支据说是用1779年在桑伟奇群岛死去的英国探险家船长詹姆士库克的遗骨刻成的夏威夷弓箭。在不久前DNA 证据宣布该弓箭并非来自于库克船长的遗骨时，奥大利亚博物馆收藏经理尤大书菲利普说：“澳大利亚博物馆里并没有库克的遗骨。”但这并不能停止博物馆在展览会上展出弓箭。“考古发现：澳大利亚博物馆的宝藏”展览中的确还展示了一个在1778年夏威夷国王卡兰尼欧普送 给库克的一个羽毛斗篷。库克是英国最伟大探险家之一，他在1770年发

34、现了“南大陆”，也就是现在的澳大利亚。此后在桑伟奇群岛被棒击致死。库克弓箭传说始于1824年，当时夏威夷国王卡莫哈莫哈在弥留之际将弓箭赐给了库克妻子的亲戚，一名伦敦外科医生威廉正当斯，并告诉他弓箭是在那次致命殴打后用库克的遗骨做成的。在19世纪90年代，弓箭被交给澳大理亚博物馆。这个传说直到与科学直接接触才停止。据菲利普说，澳大利亚和新西兰的试验室的DNA测试证实弓箭并非取材于库克的遗骨，而更可能来自动物的骨头。但是，库克迷们却不肯放弃希望。他们期待库克传说之一将会被证明是正确，并且他人部分遗骨还会被发现。正如他们所说，有证据表明库克的遗骨并不是在1779年全都葬身大海了。库克船长协会的会长克

35、利夫托马森在一个来自英国的声明中说：“在这个问题上，科技取得了胜利。我坚信某一天库克传说之一将会被证明是真的。”雪崩和安全问题雪崩是雪掺杂着空气和水沿着山体突然迅猛地滑动造成的。雪崩是造成山区人们生命和财产安全的最大危险之一。所有雪崩都是由于物质的过渡负荷造成，通常是积雪堆积过厚，很不稳固，超出了山坡面的承载能力。要确定山坡的临界承载量，可能造成突然雪崩的负荷量是一项很复杂的任务，需要衡量多个因素。通常倾斜度小于25度，大于60度的山坡发生雪崩的危险要小一些。积雪不会在陡峭的山坡上大量堆积，同样也不会在平缓的山坡上快速滑动。当雪在静止状态下的角度在35_45度之间，最可能发生人为触发的雪崩。人

36、为引发雪崩的临界角度是38度，是最易人为引发雪崩的角度。常规经验是：一个平缓的足以堆积积雪，同时陡峭的适合人们滑雪的山坡，无论角度如何，都有可能产生雪崩。此外，雪崩的危险随着使用的增加而增加，换言之，滑雪者活动得越频繁，雪崩的可能性越大。由于雪崩研究的复杂性，冬天在人烟稀少的地区旅行从来不是百分之百的安全。很好地躲避雪崩，保持安全是一个连续的过程，包括选择路线、检查积雪、了解天气状况及其他人为因素。以下几个广为人知的好习惯也可以降低风险：如果当地权威部门发布了雪崩警报，你应当予以考虑，加以注意。绝不要不加审度，就立刻接受他人意见。积雪自形成的那时就几乎注定要发生变化。认真观察地形，注意明显的雪

37、崩路径：没有植物或植物被毁坏的地方。不要在那些可能引发雪崩的人或事物下面行走。巨型建筑挑选当今世界最神奇的奇观是一个不可能完成的任务。原因是每年都有新的更令人叹为观止的建筑出现。有这样三座巨大的建筑值得人们赞叹，尽管它们可能被某些最近建成的奇观所超越。第一座：国油双峰塔。国油双峰塔在1999年建成时是世界上最高的建筑物，高452米，高高的双塔就像两支细铅笔，高耸于吉隆坡市。在41层，两个塔由一座桥连接，象征着通向城市的大门。该建筑的设计者是美国建筑师Cesar Pelli。该建筑由高强度混凝土建成，每一层都有大约1800平方米的办公区域；在底部还有一个购物中心和一个音乐厅。该建筑的其他特色是双层电梯以及建材为玻璃和钢的遮阻阳篷。第二座：米约高架桥。米约高架桥位于法国南部的Tarn山谷，2004年建成通车。它是当时世界上最高的大桥，最高点超过340米。该桥被人们描写为“世界上最神奇最美丽的大桥之一”。它是为舒缓米约的交通拥挤所建。当时的拥挤是由从巴黎到西班牙的巴塞罗那的过往车辆太多所致。该桥可以承受强震和极端气候。另外，它可以使用120年! 第三座：伊泰普水电站。伊泰普水电站是同类建筑中最大的一个。它由横跨巴拉那河的一组大坝组成，成为巴西和巴拉圭的自然边境。该建筑
