1、第一篇 Captain Cook Arrow Legend库克船长箭传说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) no Cook in the Australian

2、 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 include

3、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 HawaiiThe 1egend of Cooks arrow began in 1824 (8) wh

4、en Hawaiian 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) fight with islanders. In the 1890s the arrow was given to the Australian Museum and the legend continued (10) until it came face

5、=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) likely made 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) surethat 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雪崩和它的安全 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 caus

8、ed 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. Terrain

9、 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)be

10、tween 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 , including

12、 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

14、型建筑It is an impossible task to select the most amazing wonders of the modem world since every year more _wonderful_ constructions appear. Here are three giant structures which are worthy of our _admiration_ although they may have been surpassed by some more recent wonders.The Petronas Twin TowersThe

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

16、can _architect_ Cesar Pelli designed the skyscrapers.Constructed of high-strength concrete, the building provides around 1，800 square metres of office space _on_ every floor. And it has a shopping centre and a concert hall at the base. Other _features_ of this impressive building include double-deck

17、er lifts, and glass and steel sunshades.The MiUau BridgeThe Millau Bridge was opened in 2004 in the Tam Valley，in southern France. _at_ the time it was built，it was the worlds highest bridge, _reaching_ over 340m at the highest point. The bridge is described as one of the most amazingly beautiful br

18、idges in the world. It was built to _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 _most_ extreme seismic and climatic conditions. Besides, it is guaranteed for 120 years!The Itaipu DamT

19、he 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 Parana, _which_ forms a natural border between Brazil and Paraguay. Started in 1975 and taking 16 years to complete, the construction was carried out as

20、a joint project between the two _countries_. The dam is well-known for both its electricity output and its size. In 1995 it produced 78% of Paraguays and 25% of Brazils _energy_ needs. In its construction, the _amount_ of iron and steel used was equivalent to over 300 Eiffel Towers. It is a _truly_

21、amazing wonder of engineering.第四篇 Animals “Sixth Sense” 动物的 第六个感觉 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. This phenomenon adds

22、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 are dead, not （4）

23、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 inland at Yala Natio

24、nal 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 proven,” said Matth

25、ew 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 certain （12）phenomenon,

26、 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 “sixth sense”-or

27、（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 Singing Alarms Coul

28、d Save the Blind歌唱警报可以解救盲人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 University of Leeds

29、, 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 that the alar

30、ms 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 their way out

31、 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 pinpointed more ea

32、sily 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 large grant fr

The car is fitted with a remote immobilizer and a radio signal from a control center miles away will ensure that once

34、 the thief switches the engine 1 off , he will not be able to start it again. For now, such devices 2 are only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and 3 should be av

35、ailable to ordinary cars in the UK 4 in two months. The idea goes like this. A control box fitted to the carincorporates 5 a miniature cellphone, a microprocessor and memory, and a GPS satellite positioning receiver. 6 If the car is stolen, a coded cellphone signal will tell the unit to block the ve

36、hicles engine management system and prevent the engine 7 being restarted. There are even plans for immobilizers 8 that shut down vehicles on the move, though there are fears over the safety implications of such a system. In the UK. an array of technical fixes is already making 9 life harder for car

37、thieves. “The pattern of vehicles crime has changed,” says Martyn Randall of Thatcham, a security research organization based in Berkshire that is funded in part 10 by the motor insurance industry. He says it would only take him a few minutes to 11 teach a novice how to steal a car, using a bare min

38、imum of tools. But only if the car is more than 10 years old. Modern cars are a far tougher proposition, as their engine management computer will not 12 allow them to start unless they receive a unique ID code beamed out by the ignition key. In the UK, technologies like this 13 have helped achieve a

39、 31 per cent drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars. Often by getting hold of the owners keys in a burglary. In 2000, 12 per cent of vehicles stolen in the UK were taken using the owners keys double the previous years fi

40、gure. Remote-controlled immobilization system would 14 put a major new obstacle in the criminals way by making such thefts pointless. A group that includes Thatcham, the police, insurance companies and security technology firms have developed standards for a system that could goon the market sooner

41、than the 15 customer expects.第七篇 An intelligent car一辆聪明的汽车Driving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all (1) these and can control a fast-moving car. But how does an intelligent car control itself?There is a virtual driver

42、in the smart car. This virtual driver has “eyes,”“brains”，“hands” and “feet”，too. The mini-cameras (2) on each side of the car are his “eyes,” which observe the road and conditions ahead of it. They watch the (3) traffic to the cars left and right. There is also a highly (4) automatic driving system

43、 in the car. It is the built-in computer, which is the virtual drivers “brain. ” His “brain” calculates the speeds of (5) other moving cars near it and analyzes their positions. Basing on this information, it chooses the right (6) path for the intelligent cars, and gives (7) instructions to the “han

44、ds”and “feets”to act accordingly. In this way, the virtual driver controls his car.What is the virtual drivers best advantage? He reacts (8) quickly. The mini-cameras are (9) sending images continuously to the “brain”. It (10) completes the processing of the images within 100 milliseconds. However,

45、the worlds best drier (11) at least needs one second to react. (12) Besides, when he takes action, he needs one more second.The virtual driver is really wonderful. He can reduce the accident (13) rate considerably on expressway. In this case. Can we let him have the wheel at any time and in any plac

46、e? Experts (14) warn that we cannot do that just yet. His ability to recognize things is still (15) limited. He can now only drive an intelligent car on expressways.第八篇 Why India Needs Its Dying Vultures 印度为什么需要濒临灭亡的秃鹰The vultures in question may look ugly and threatening, but the sudden sharp _ dec

47、line _ in three species of Indias vultures is producing alarm rather than celebration, and it presents the world with a new kind of environmental _ problem _ The dramatic decline in vulture numbers is causing widespread disruption to people living in the same areas as the _ birds _ . It is also caus

48、ing serious public health problems _ across _ the Indian sub-continent.While their reputation and appearance may be unpleasant to many Indians，vultures have_ long _played a very important role in keeping towns and villages all over India clean. It is_ because _they feed on dead cows. In India, cows

49、are sacred animals and are _ traditionally _ left in the open when they die in their thousands upon thousands every year.The disappearance of the vultures has _ led to _ an explosion in the numbers of wild dogs feeding on the remains of these dead animals. There are fears that rabies may _ increase

50、_ as a result. And this terrifying disease may ultimately affect humans in the region, since wild dogs are its main carriers. Rabies could also spread to other animal species, causing an even greater problem in the _ future _.The need for action is _ urgent _, so an emergency project has been launch

51、ed to _ find_ a solution to this serious vulture problem. Scientists are trying to identify the disease causing the birds，deaths and, if possible, develop a cure.Large-scale vulture _ deaths _ were first noticed at the end of the 1980s in India. A population survey at that time showed that the three

52、 species of vultures had declined _ by _ over 90 per cent. All three species are now listed as “critically endangered”. As most vultures lay only single eggs and _ take _ about five years to reach maturity, reversing their population decline will be a long and difficult exercise.第九篇Wonder Webs惊奇网络 S

53、pider webs are more than homes, and they are ingenious traps. And the worlds best web spinner may be the Golden Orb Weaver spider. The female Orb Weaver spins a web of fibers thin enough to be invisible to insect prey, yet (1)tough enough to snare a flying bird without breaking. The secret of the we

54、bs strength? A type of super-resilient (2)silk called dragline. When the female spider is ready to (3)weave the webs spokes and frame, she uses her legs to draw the airy thread out through a hollow nozzle in her belly. Dragline is not sticky, so the spider can race back and forth along (4)it to spin

55、 the webs trademark spiral.恒星英语论坛 Unlike some spiders that weave a new web every day, a Golden Orb Weaver (5)reuses her handiwork until it falls apart, sometimes not for two years. The silky thread is five times stronger than steel by weight and absorbs the force of an impact three times better than

56、 Kevlar, a high-strength human-made (6)material used in bullet-proof vests. And thanks to its high tensile strength, or the ability to resist breaking under the pulling force called tension, a single strand can stretch up to 40 percent longer than its original (7)length and snap back as well as new.

57、 No human-made fiber even comes (8)close . It is no (9)wonder manufacturers are clamoring for spider silk. In the consumer pipeline: High-performance fabrics for athletes and stockings that never run. Think parachute cords and suspension bridge cables. A steady (10)supply of spider silk would be wor

58、th billions of dollars but how to produce it? Harvesting silk on spider farms does not (11)work because the territorial arthropods have a tendency to devour their neighbors. Now, scientists at the biotechnology company Nexia are spinning artificial silk modeled after Golden Orb dragline. The (12)fir

59、st step: extract silk-making genes from the spiders. Next, implant the genes into goat egg cells. The nanny goats that grow from the eggs secrete dragline silk proteins in their (13)milk . “The young goats pass on the silk-making gene without (14)any help from us,” says Nexia president Jeffrey Turne

60、r. Nexia is still perfecting the spinning process, but they hope artificial spider silk will soon be snagging customers (15)as fast as the real thing snags bugs. 第十篇 Chicken Soup for the SoulChicken Soup for the Soul：Comfort Food Fights Loneliness Mashed potatoes, macaroni and cheese, may be bad for

61、 your arteries but according to a study in Psychological Science, theyre good for your heart and emotions The study focuses on “comfort food” and how it makes people feel For me personally ,food has always played a big role in my family,” says Jordan Troisi, a graduate student at the University of B

62、uffalo, and lead author on the studyThe study came out of the research program of his coauthor Shira GabrielIt has looked at non-human things that may affect human emotionsSome people reduce loneliness by bonding with their favorite TV show, building virtual relationships with a pop song singer or l

63、ooking at pictures of loved onesTroisi and Gabriel wondered if comfort food could have the same effect by making people think of their nearest and dearest. In one experiment, in order to make participants feel lonely, the researchers had them write for six minutes about a fight with someone close to

64、 themOthers were given an emotionally neutral writing assignment. Then, some people in each group wrote about the experience of eating a comfort food and others wrote about eating a new food Finally ,the researchers had participants complete questions about their levels of loneliness Writing about a

65、 fight with a close person made people feel lonelyBut people who were generally secure in their relationships would feel less lonely by writing about a comfort foodWe have found that comfort foods are consistently associated with those close to ussays TroisiThinking about or consuming these foods later then serves as a reminder of those close othersIn their essays on comfort food, many people wrote about the experience of eating food with family and friends. In another experiment, eating
