　　April Fools' Special: History's Hoaxes

　　Happy April Fools' Day. To mark the occasion, National Geographic News has compiled a list of some of the more memorable hoaxes in recent history. They are the lies, darned(可恨的) lies, and whoppers(弥天大谎)that have been perpetrated on the gullible(易受骗的)and unsuspecting to fulfill that age-old desire held by some to put the joke on others.

　　Internet Hoaxes

　　The Internet has given birth to a proliferation(增殖)of hoaxes. E-mail inboxes are bombarded on an almost daily basis with messages warning of terrible computer viruses that cause users to delete benign(良性)chunks of data from their hard drives, or of credit card scams that entice the naive to give all their personal information, including passwords and bank account details, to identity thieves. Other e-mails give rise to wry(歪曲的)chuckles, which is where this list begins.

　　Ban Dihydrogen Monoxide(一氧化二氢)

　　City officials in Aliso Viejo, California, were so concerned about the dangers of dihydrogen monoxide that they scheduled a vote last month on whether to ban foam(泡沫)cups from city-sponsored events after they learned the chemical was used in foam-cup production.

　　Officials called off the vote after learning that dihydrogen monoxide is the scientific term for water.

　　"It's embarrassing," city manager David J. Norman told the Associated Press. "We had a paralegal(律师助手)who did bad research."

　　Indeed, the paralegal had fallen victim to an official-looking Web site touting the dangers of dihydrogen monoxide. An e-mail originally authored in 1990 by Eric Lechner, then a graduate student at the University of California, Santa Cruz, claimed that dihydrogen monoxide "is used as an industrial solvent and coolant, and is used in the production of Styrofoam(聚苯乙烯泡沫塑料)."

　　Other dangers pranksters(爱开玩笑的人)associated with the chemical included accelerated corrosion and rusting, severe burns, and death from inhalation.

　　Versions of the e-mail continue to circulate today, and several Web sites, including that of the Coalition to Ban DHMO, warn, tongue-in-cheek, of water's dangers.

　　Alabama Changes Value of Pi

　　The April 1998 newsletter put out by New Mexicans for science and Reason contains an article titled "Alabama Legislature Lays Siege to Pi". It was penned by April Holiday of the Associmated Press (sic) and told the story of how the Alabama state legislature voted to change the value of the mathematical constant Pi from 3.14159 to the round number of 3.

　　The ersatz(假的)news story was written by Los Alamos National Laboratory physicist Mark Boslough to parody(滑稽地模仿)legislative and school board attacks on the teaching of evolution in New Mexico.

　　At Boslough's suggestion, Dave Thomas, the president of New Mexicans for science and Reason, posted the article in its entirety to the Internet newsgroup Talk. Origins on April 1. (The newsgroup hosts a lively debate on creation vs. evolution.) Later that evening Thomas posted a full confession to the hoax. He thought he had put all rumors to bed.

　　But to Thomas's surprise, however, several newsgroup readers forwarded the article to friends and posted it on other newsgroups.

　　When Thomas checked in on the story a few weeks later, he was surprised to learn that it had spread like wildfire. The telltale signs of the article's satirical intent, such as the April 1 date and misspelled "Associmated Press" dateline, had been replaced or deleted.

　　Alabama legislators were bombarded with calls protesting the law. The legislators explained that the news was a hoax. There was not and never had been such a law.

　　TV and Newspaper Hoaxes

　　Before the advent of the Internet, and even today, traditional media outlets such as newspapers, radio, and television, have sometimes hoaxed their audiences. The deceptions run the gamut from purported natural disasters to wishful news.

　　Swiss Spaghetti (意大利式细面条) Harvest

　　Alex Boese, curator of the Museum of Hoaxes, a regularly updated Web site that also appeared in book form in November 2002, said one of his favorite hoaxes remains one perpetrated by the British Broadcasting Company.

　　On April 1, 1957, the BBC aired a report on the television news show Panorama about the bumper spaghetti harvest in southern Switzerland.

　　Viewers watched Swiss farmers pull pasta off spaghetti trees as the show's anchor, Richard Dimbleby, attributed the bountiful harvest to the mild winter and the disappearance of the spaghetti weevil.

　　The broadcaster detailed the ins and outs of the life of the spaghetti farmer and anticipated questions about how spaghetti grows on trees. Thousands of people believed the report and called the BBC to inquire about growing their own spaghetti trees, to which the BBC replied, "Place a sprig of spaghetti in a tin of tomato sauce and hope for the best."

　　"It was a great satirical effect about British society," Boese said. "British society really was like that at that time. The British have a tendency to be a bit insulated(绝缘的) and do not know that much about the rest of Europe."

　　Taco Liberty Bell

　　On April 1, 1996, readers in five major U.S. cities opened their newspapers to learn from a full page announcement that the Taco Bell Corporation had purchased the Liberty Bell from the U.S. government. The announcement reported that the company was relocating the historic bell from Philadelphia, Pennsylvania, to Irvine, California. The move, the corporation said in the advertisement, was part of an "effort to help the national debt".

　　Hundreds of other newspapers and television shows ran stories related to the press release on the matter put out by Taco Bell's public relations firm, PainePR. Outraged citizens called the Liberty Bell National Historic Park in Philadelphia to express their disgust. A few hours later the public relations firm released another press announcement stating that the stunt was a hoax.

　　White House press secretary Mike McCurry got into the act when he remarked that the government would also be "selling the Lincoln Memorial to Ford Motor Company and renaming it the Lincoln-Mercury Memorial".

　　Crop Circles

　　Strange, circular formations began to appear in the fields of southern England in the mid-1970s, bringing busloads of curious onlookers, media representatives, and believers in the paranormal out to the countryside for a look.

　　A sometimes vitriolic(讽刺的)debate on their origins has since ensued(跟着发生), and the curious formations have spread around the world, becoming more and more elaborate as the years go by.

　　Some people consider the crop formations to be the greatest works of modern art to emerge from the 20th century, while others are convinced they are signs of extraterrestrial communications or landing sites of UFOs.

　　The debate rages even today, although in 1991 Doug Bower and Dave Chorley, two elderly men from Wiltshire County, came forward and claimed responsibility for the crop circles that appeared there over the preceding 20 years. The pair made the circles by pushing down nearly ripe crops with a wooden plank suspended from a rope.

　　Moon Landing—a Hoax?

　　Ever since NASA sent astronauts to the moon between 1969 and 1972, skeptics have questioned whether the Apollo missions were real or simply a ploy to one-up(领先)the Soviet Union during the Cold War. The debate resurfaced and reached crescendo levels in February 2001, when For television aired a program called Conspiracy Theory: Did We Land on the Moon?

　　Guests on the show argued that NASA did not have the technology to land on the moon. Anxious to win the space race, NASA acted out the Apollo program in movie studios, they said. The conspiracy theorists pointed out that the pictures transmitted from the moon do not include stars and that the flag the Americans planted on the moon is waving, even though there is though to be no breeze on the moon.

　　NASA quickly refuted these claims in a series of press releases, stating that any photographer would know it is difficult to capture something very bright and very dim on the same piece of film. Since the photographers wanted to capture the astronauts striding across the lunar surface in their sunlit space suits, the background stars were too faint to see.

　　As for the flag, NASA said that the astronauts were turning it back and forth to get in firmly planted in the lunar soil, which made it wave.

　　1. Some people have the age-old desire to put the joke on others.

　　2. According to the passage, the only form of Internet hoaxes is e-mail hoax.

　　3. Dihydrogen monoxide is a very dangerous chemical, which is often used as an industrial solvent.

　　4. Dihydrogen monoxide can accelerate corrosion and rusting, and cause sever burns and even death from inhalation.

　　5. The reason why the ersatz news that Alabama changed the value of Pi spread wildly was that ________ forwarded the article to friends and posted it on other newsgroups.

　　6. Traditional media outlets such as ________ may still hoax their audiences nowadays.

　　7. According to Boese, many people believed the report of Swiss spaghetti harvest because the British did not know ________.

　　8. According to a hoax announcement, the Taco Bell Corporation bough the Liberty Bell and moved it to Irvine to help ________.

　　9. The crop circles were thought to be the greatest works of modern art, the signs of ________ or landing sites of UFOs.

　　10. Some people thought that NASA acted out the Apollo program in movie studios partially because the pictures transmitted from the moon do not include ________.

Part IV Reading Comprehension (Reading in Depth) (25 minutes)

　　Section A

　　Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words on Answer Sheet 2.

　　Questions 47 to 51 are based on the following passage.

　　Wild ducks and other migratory(迁移的) birds could be important carriers of deadly bird flu, researchers say. Even so, the infectious-disease experts say there is no solid basis for killing wild birds to protect poultry and minimize the risk of human infection.

　　The European team investigating the global spread of the H5N1 strain of avian influenza(禽流感)says certain duck species may be infecting wild bird populations. Geese and wading birds are also possible vectors(带菌者)of the virus, the team says.

　　The team's study was led by Björn Olsen of Umea University in Sweden. Olsen runs Europe's largest wild-bird flu monitoring program.

　　Studies have shown that influenza viruses in lake water, generally passed via bird feces(粪), can stay infectious for up to 30 days. The migration or feeding behavior of dabbling ducks could at least partially explain the spread of the H5N1 strain of bird flu, the researchers add.

　　This group of duck species includes mallards, teal, pintails, and others that feed at or near the surface, where viruses in water are most likely to be picked up. Perhaps as a result, dabblers have the highest known rates of avian influenza infection, the study says. For instance, nearly 13 percent of mallards tested positive for bird flu. Other species tested include the American black duck (18.1 percent), blue-winged teal (11.5 percent), and northern pintail (11.2 percent).

　　However, bird flu viruses appear to exist in ducks in a low-pathogenic form, meaning infection doesn't usually lead to severe illness and death.

　　"Dabbling ducks are for sure the prime hosts for low pathogenic viruses," said study co-author Ron Fouchier, a virologist at the Erasmus Medical Center in Rotterdam, Netherlands. "But the big question is, how much of our knowledge about these viruses can we translate to high-pathogenic viruses such as the H5N1 strain of bird flu?"

　　In poultry avian viruses can mutate(变异)into more virulent influenza strains, including H5N1. If this mutated virus then finds its way back into wild populations, the birds could then spread the disease through migration.

　　Some scientists have argued that wild birds infected with HN51 would be too ill to migrate. Swans, for instance, appear to be particularly vulnerable to the strain. "Swans apparently drop dead quite easily, but they are unlikely to be the vector because they are not going to fly very far if they are dead," Fouchier said.

　　But the study team says that some birds that have been purposely infected for the sake of research show that wild birds can survive H5N1. "For some reason H5N1 has adapted so it no longer kills dabbling ducks," Fouchier said. This means the ducks may be able to spread the virus over a wide area.

　　The study team says migratory geese may also be vectors, because they often graze in huge flocks, a practice that could encourage transmission.

　　Migrating ducks, the researchers add, "could provide an intercontinental bridge" for bird flu to North America, which has not yet had any known cases of H5N1.

　　47. According to the author, what may be the possible carriers of bird flu?

　　48. The main sources of influenza viruses in lake water are ________, which may stay infectious for up to 30 days.

　　49. By saying "bird flu viruses appear to exist in ducks in a low-pathogenic form" (Para. 6), the author suggests that infection ________.

　　50. On what condition can the birds spread the influenza through migration?

　　51. According to the study team, ________ is a practice that can encourage transmission of the bird flu.

　　Section B

　　Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked [A], [B], [C] and [D]. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the center.

　　Passage One

　　Questions 52 to 56 are based on the following passage.

　　For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human inter-living, long enough to set back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument.

　　Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets on the issue of nuclear energy. "Give it back," say some of the voices, "It doesn't really work, we've tried it and it doesn't work. Go back three hundred years and start again on something else less chancy for the race of man."

　　The principle discoveries in this century, taking all in all, are the glimpses of the depth of our ignorance of nature. Things that used to seem clear and rational, and matters of absolute certainty-Newtonian mechanics, for example-have slipped through our fingers; and we are left with a new set of gigantic puzzles, cosmic uncertainties, and ambiguities. Some of the laws of physics are amended every few years; some are canceled outright; some undergo revised versions of legislative intent as if they were acts of Congress.

　　Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear: the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today's imagining.

　　It is not just that there is more to do, there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves.

　　52. What CANNOT be inferred from the first paragraph?

　　[A] Scientific experiments in the past three hundred years have produced many valuable items.

　　[B] For three hundred years there have been people holding a hostile attitude toward science.

　　[C] Modern civilization depends on science so man supports scientific progress unanimously.

　　[D] Some people think three hundred years is not long enough to set back for critical appraisal of scientific method.

　　53. The principle discovery in this century shows ________.

　　[A] man has overthrown Newton's laws of physics

　　[B] man has solved a new set of gigantic puzzles

　　[C] man has lost many scientific discoveries

　　[D] man has given up some of the once accepted theories

　　54. Now scientists have found in the past few years ________.

　　[A] the exposure of DNA to the public is unnecessary

　　[B] the tiny cell in DNA is a neat little machine

　　[C] man knows nothing about DNA

　　[D] man has much to learn about DNA

　　55. The writer's main purpose in writing the passage is to say that ________.

　　[A] science is just at its beginning

　　[B] science has greatly improved man's life

　　[C] science has made profound progress

　　[D] science has done too little to human beings

　　56. The writer's attitude towards science is ________.

　　[A] critical [B] approving [C] neutral [D] regretful

　　Passage Two

　　Questions 57 to 61 are based on the following passage.

　　Here amid the steel and concrete canyons, green grass grows. A hawthorn tree(山楂树) stands in new soil, and freshly dug plants bend in the wind.

　　But Chicago City Hall here seems an unlikely spot for a garden of any variety—especially 20,000 square feet of gardens—on its roof.

　　As one of a handful of similar projects around the country, the garden is part of a $1.5 million demonstration projected by the city to reduce its "urban heat islands", said William Abolt, the commissioner of the Department of Environment.

　　Heat islands-dark surfaces in the city, like rooftops-soak up heat. The retention can bake a building, making it stubborn to cooling.

　　The roof of City Hall, a 90-year-old gray stone landmark on LaSalle Street in the heart of downtown, has been known to reach temperature substantially hotter than the actual temperature on the street below.

　　The garden will provide greenery and shade. "And that," said the city officials, "will save the city dollars on those blistering summer days." The project savings from cooling is about $4,000 a year on a new roof whose life span is about 50 percent longer than that of a traditional roof.

　　The sprawling open-air rooftop garden is being carefully built on a multi-tiered bed of special soil, polystyrene, egg-carton-shaped cones and "waterproof membrane" mall to keep the roof from leaking, or caving under the normal combined weight of soil, rain and plant life.

　　The design calls for soil depths of 4 inches to 18 inches. When the last plants and seedlings are buried and the last bit of compost is laid, the garden will have circular brick stepping-stones winding up to hills.

　　"The primary focus of what we want to do was to establish this laboratory on the top of City Hall to get people involved and understanding their impact on the environment and how the little things can make an impact on the quality of life", Mr. Abolt said, adding that the plants also help to clear the air.

　　Rooftop gardens, in places where concrete jungles have erased plants and trees, are not new, not even in Chicago. Arms of greenery dangling over terraces or sprouting from rooftops, common in Europe, are becoming more so in the United States as people become increasingly conscious about the environment.

　　Richard M. Daley, who urged the environmental department to look into the project after noticing rooftop gardens in Hamburg, Germany a few years ago, has praised the garden as the first of its kind on a public building in the country.

　　It will hold thousands of plants in more than 150 species-wild onion and butterfly weed, sky-blue aster and buffalo grass-to provide data on what species adapt best. Small plants requiring shallow soil depths were chiefly selected.

　　57. The rooftop garden project ________.

　　[A] is common and popular in the country

　　[B] is a demonstration project and costs the city government 1.5 million dollars

　　[C] will make the ordinary cooling down of the city in summer unnecessary

　　[D] aims at getting people involved and understanding their impact on the environment

　　58. What can we learn about the City Hall?

　　[A] It was built ninety years ago and is the most outstanding feature in the center of the city.

　　[B] It is originally proper to build a garden on the top of the City Hall.

　　[C] The temperature on its top is a little bit lower than that on the street below.

　　[D] It is the first building in America to have a garden on it.

　　59. Which of the following statements is TRUE?

　　[A] Every year, Chicago spends about $ 4,000 on cooling the city.

　　[B] The design of the garden on the City Hall specially takes into consideration the weight the roof can stand.

　　[C] The Mayor urged the environmental department to look into rooftop gardens in Hamburg and build similar ones in America.

　　[D] Heat islands mainly refer to those dark-colored rooftops which receive and retain heat and will not easily release the heat.

　　60. Why should the rooftop garden be built on the top of City Hall other than on any other buildings?

　　[A] Because the City Hall is large.

　　[B] Because the mayor had urged the environmental department to do so.

　　[C] Because it can make people understand their impact on environment better through a public building.

　　[D] Because the experts just want to make the City Hall a convenient laboratory.

　　61. The word "substantially" (Line 2, Para. 5) most likely means ________.

　　[A] a little bit [B] in fact [C] materially [D] considerably

　Part V Error Correction (15 minutes)

参考答案及详解

Part I Writing

　　Salary or Interest

　　Upon graduation, virtually all college students will confront the problem of choosing their careers. It is truly a tough choice. Students’ opinions differ greatly on this issue. Some hold that priority should be given to their interest in the job, but others take the attitude that salary is the most critical factor influencing their career choices.

　　As for myself, I prefer the latter view. A well-paid job exerts a tremendous fascination on a great number of people, with no exception to me. Although it might be impossible to measure the value of one’s job in terms of money, salary counts most when I choose my future career. In my view, our career choices largely depend on how and where we have been brought up. I come from a poor urban family and my parents are both laid-off workers. In order to finance my tuition, they have been working hard over the past four years. As the only son in my family, I have to shoulder the burden of supporting my family.

　　In short, salary is the first consideration in my choice of career.

　　58. A 细节题。由文章第五段可知，市政厅的屋顶有90年的历史，即市政厅建于90年前，且是市中心最著名的建筑，所以A正确。第二段第一句中的an unlikely spot否定了B项中的originally proper。根据第五段可排除C，根据第十段not new可排除D。

　　59. B 推断题。由文章第七段可知，市政厅屋顶花园是精心建造而成的，可以避免屋顶渗漏，或是在土、雨和植物相混合的重量之下坍塌，由此可知，屋顶花园的设计充分考虑到了屋顶能承受的重量，所以B正确。

　　60. C 细节题。由文章第九段可知，在市政厅大楼上修建屋顶花园主要是为了让人们了解自己对环境的影响，所以C正确。虽然该段也提到了laboratory，但指的是让人们了解自己对环境的影响的“实验室”，而并不是真正做实验的实验室，故排除D。

　　61. D 语义题。被考查词在句中用于修饰比较级hotter，分析句意可知，此处应表示强调，突出屋顶的温度要比街上的温度高出很多，选项中只有D(相当大地)最符合。A(一点)，B(实际上)，C(本质上地)均应排除。

Part V Error Correction

　　62. after→before

　　根据上下文逻辑，此处显然指孩子学会说话之前的听力，而非之后，故将after改为before。

　　63. like→as

　　like和as都有“像”的意思，但是此处要求填人一个具有“作为”之意的单词，故将like改为as。

　　64. in→by

　　此处应为表示方式的借词，故用by，意为“以某种方式”。

　　65. 1ead→leads

　　此处句子的主语是attempt，而不是动词前面的words，所以要用单数第三人称的形式，将lead改为leads。

　　66. 在they前增加that

　　it是句子的形式主语，they enjoy making noises才是句子的逻辑主语，由于是主语从句，故引导词that是不能省略的。

　　67. noise→noises

　　one or two按照复数对待，所以后面是noises。

　　68. particular→particularly

　　修饰形容词indicative应该使用副词particularly。

　　69. can→cannot

　　根据上下文，此处应为否定，故使用cannot。

　　70. making→made

　　此处指“发出的声音和说的话”，sound和make间是被动关系，故使用过去分词作定语。

　　71. 在point后加at

　　定语从句的关系代词指代先行词point，可是从句中缺少的是状语，因此在which前加上介词at，那么at which在句子中作地点状语。

　　Part VI Translation

　　72. was the best thing that could have ever happened to me

　　“发生在我身上的……事情”可译为以“事情”为先行词的定语从句，其时态应为一般现在完成时。因先行词的限定词为形容词最高级best，因此关系代词应为that而不是which;;“(事情等)发生在某人身上”可用happen to sb.来表示。

　　73. he(should)be sent to hospital at once

　　“送”可以直接译为send，此处没有明确的施动者，因此要用被动语态;该句符合it’s necessary that+(should)do的结构，主语从句的谓语应为(should)be sent to hospital;“马上”可译为at once或immediately，故此处还可译为he(should)be sent to hospital immediately。

　　74. so that you can stay conscious daily of what you’ve got from others

　　结合给出的中英文可知，“这样”表示的是一种因果关系，可译为so that;“注意到”可译为stay conscious of;“每天”可译为daily置于谓语和宾语之间，也可译为each day置于句末，故此处还可译为so that you can stay conscious of what you’ve got from others each day。

　　75. he agreed with my decision and decided to carry out that plan

　　分析句子结构，所译部分应为suggest的宾语从句。“赞成”应译为agree with sb./sth.，“执行”应译为carry out。suggest在表示“建议”时，其宾语从句的谓语要用“should+动词原形”的形式，而此处意为“暗示”，宾语从句的谓语与主句时态保持一致即可，应为agreed with…and decided to…。

　　76. can we expect our country to take a new face

　　分析句子结构可知，所译部分应为完整的句子。给出的英文中，only修饰的介词短语with combined efforts位于句首，因此所译句子需部分倒装。“期望”可以译为expect sb./sth. to do sth.，“有新的面貌”可以译为take a new face。
