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(彌天大謊)that have been perpetrated on the gullible(易受騙的)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(一氧化二氫)
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(律師助手)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(愛開玩笑的人)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 (意大利式細(xì)面條) 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(絕緣的) 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(諷刺的)debate on their origins has since ensued(跟著發(fā)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(領(lǐng)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(遷移的) 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(帶菌者)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(糞), 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(變異)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. Someof 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

[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(山楂樹) 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 VI Translation (5 minutes)

參考答案：
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.

59. B 推斷題。由文章第七段可知，市政廳屋頂花園是精心建造而成的，可以避免屋頂滲漏，或是在土、雨和植物相混合的重量之下坍塌，由此可知，屋頂花園的設(shè)計(jì)充分考慮到了屋頂能承受的重量，所以B正確。
60. C 細(xì)節(jié)題。由文章第九段可知，在市政廳大樓上修建屋頂花園主要是為了讓人們了解自己對環(huán)境的影響，所以C正確。雖然該段也提到了laboratory，但指的是讓人們了解自己對環(huán)境的影響的“實(shí)驗(yàn)室”，而并不是真正做實(shí)驗(yàn)的實(shí)驗(yàn)室，故排除D。
61. D 語義題。被考查詞在句中用于修飾比較級(jí)hotter，分析句意可知，此處應(yīng)表示強(qiáng)調(diào)，突出屋頂?shù)臏囟纫冉稚系臏囟雀叱龊芏�，選項(xiàng)中只有D(相當(dāng)大地)最符合。A(一點(diǎn))，B(實(shí)際上)，C(本質(zhì)上地)均應(yīng)排除。
Part VI Translation
72. was the best thing that could have ever happened to me
“發(fā)生在我身上的„„事情”可譯為以“事情”為先行詞的定語從句，其時(shí)態(tài)應(yīng)為一般現(xiàn)在完成時(shí)。因先行詞的限定詞為形容詞最高級(jí)best，因此關(guān)系代詞應(yīng)為that而不是which;;“(事情等)發(fā)生在某人身上”可用happen to sb.來表示。
73. he(should)be sent to hospital at once
“送”可以直接譯為send，此處沒有明確的施動(dòng)者，因此要用被動(dòng)語態(tài);該句符合it’s necessary that+(should)do的結(jié)構(gòu)，主語從句的謂語應(yīng)為(should)be sent to hospital;“馬上”可譯為at once或immediately，故此處還可譯為he(should)be sent to hospital immediately。
74. so that you can stay conscious daily of what you’ve got from others 結(jié)合給出的中英文可知，“這樣”表示的是一種因果關(guān)系，可譯為so that;“注意到”可譯為stay conscious of;“每天”可譯為daily置于謂語和賓語之間，也可譯為each day置于句末，故此處還可譯為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 分析句子結(jié)構(gòu)，所譯部分應(yīng)為suggest的賓語從句。“贊成”應(yīng)譯為agree with sb./sth.，“執(zhí)行”應(yīng)譯為carry out。suggest在表示“建議”時(shí)，其賓語從句的謂語要用“should+動(dòng)詞原形”的形式，而此處意為“暗示”，賓語從句的謂語與主句時(shí)態(tài)保持一致即可，應(yīng)為agreed with„and decided to„。
76. can we expect our country to take a new face
分析句子結(jié)構(gòu)可知，所譯部分應(yīng)為完整的句子。給出的英文中，only修飾的介詞短語with combined efforts位于句首，因此所譯句子需部分倒裝。“期望”可以譯為expect sb./sth. to do sth.，“有新的面貌”可以譯為take a new face。
