One of the first men to produce designs for aircraft was Leonardo da Vinci, an Italian artist who lived in the fifteenth century. However, it was not until the eighteenth century that people began to fly, or perhaps it would be better to say float, across the countryside in balloons. The first hot-air balloon was made in April 1783 by the Montgolfier brothers in France.In the following years many flights were made by balloon. Some of the flights were for pleasure and others were for delivering mail and for military purposes, such as observation and even bombing. However, in the late nineteenth century, airships superseded balloons as a form of transport.Airships came after balloons. The first powered and manned flight was made by a Frenchman, Giffard, in September 1852. His airship, powered by steam, traveled twenty-seven kilometers from Paris to Trappes at a speed of eight kilometers per hour. However the days of the airship were numbered as the aero plane became increasingly safe and popular.ExerciseDirections: Listen to the passage and write down the gist and the key words that help you decide.1.This passage is about the early history of flying.2.The key words are designs, an Italian artist, fifteenth century, eighteenthcentury, fly, float, balloons, hot-air balloon, April 1783, airships, September 1852, aeroplane.Section Two Listening ComprehensionPart 1 DialogueBuying a CarA: Good morning, can I help you?B: Yes, I'm interested in buying a car.A: Have you anything in mind?B: Not really.A: What price are youthinking of?B: Not more than £13,500.A: Let's see now ...

The starts were all made from a point on the level sand about 200 feet west of our camp, which is located a quarter of a mile north of the Kill Devil sand hill, in Dare County, North Carolina.The wind at the time of the flights had a velocity* of 27 miles an hour at 10a.m., and 24 miles an hour at noon, as recorded by the anemometer* at the Kitty Hawk Weather Bureau Station.The flights were directly against the wind. Each time the machine started from the level ground by its own power alone with no assistance from gravity or any other source whatever.After a run of about 40 feet along a monorail* track, which held the machine 8 inches (20 centimeters) from the ground, it rose from the track and under the direction of the operator climbed upward on an inclined course till a height of 8 or 10 feet from the ground was reached, after which the course was kept as near horizontal as the wind gusts and the limited skill of the operator would permit.Into the teeth of a December gale the "Flyer" made its way forward with a speed of 10 miles an hour over the ground and 30 to 35 miles an hour through the air.It had previously been decided that for reasons of personal safety these first trials should be made as close to the ground as possible. The height chosen was sufficient for maneuvering* in so gusty a wind and with no previous acquaintance with the conduct of the machine and its controlling mechanisms. Consequently the first flight was short.The succeeding flights rapidly increased in length and at the fourth trial a flight of 59 seconds was made, in which time the machine flew a little more than half a mile through the air and a distance of 852 feet over the ground.The landing was due to a slight error of judgment on the part of the aviator. After passing over a little hummock* of sand, in attempting to bring the machine down to the desired height, the operator turned the rudder* too far, and the machine turned downward more quickly than had been expected. The reverse movement of the rudder was a fraction of a second too late to prevent the machine from touching the ground and thus ending the flight.As winter was already well set in, we should have postponed the trials to a more favorable season, but we were determined to know whether the machine possessed sufficient power to fly, sufficient strength to withstand the shocks of landings and sufficient capacity of control to make flight safe in boisterous* winds, as well as in calm air.Exercise A Pre-listening QuestionOrville Wright (1871-1948), American aeronautical engineer, famous for his role in the first controlled, powered flight in a heavier-than-air machine and for his participation in the design of the aircraft's control system. Wright worked closely with his brother, Wilbur Wright (1867-1912), American aeronautical engineer, in designing and flying the Wright airplane.During the years 1900, 1901, 1902, and 1903, the two brothers developed the first effective airplane. At Kitty Hawk, North Carolina, on December 17, 1903, Orville Wright made the first successful flight of a piloted, heavier-than-air, self-propelled craft, called the Flyer. The third Flyer, which the Wrightsconstructed in 1905, was the world's first fully practical airplane. It could bank, turn, circle, make figure eights, and remain in the air for as long as the fuel lasted, up to half an hour on occasion.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

Before his victory here, he had missed the halfway cuts in five straight tournaments. He hopes he can again find his form during the next four days, as he is currently 132nd on the money list.The player who is number-one on golf's money list and in the world rankings, American Tiger Woods, decided to skip this event after winningthe rain-delayed Memorial Open in (Dublin) Ohio on Monday.Compatriot* Jeff Sluman says even Tiger has to take periodic breaks.He's unbelievable. He's got an opportunity, as I said even a couple years ago, if he stays healthy and does the right things, he can maybe be the best golfer of all time, and he's showing right now what he can do. The kid is just a fabulous, fabulous player, but he can't play every week."Eight of the past 10 Kemper Open winners are in this year's field of 156 golfers, who are vying for three million dollars in prize money.

To get here, the Maryland Terrapins had to beat three teams with great basketball traditions: Kentucky, Connecticut and Kansas.Now they face another, Indiana. while Maryland was one of the four top seeds in this 65-team tournament, the Indiana Hoosiers* were a fifth seed, and virtually no one expected them to reach the title game*. But they knocked off defending champion Duke in the third round, and in the semifinals they upset Oklahoma.Maryland coach Gary Williams knows it will take a solid effort to win. "Any team that's gotten to where Indiana has gotten, you don't look at their record. You look at how they're playing now, how they play. Any time a team plays team defense like they do, they have a chance to beat anybody. That's what concerns me the most, their ability to play together as a unit, because a lot of times you can play with anybody when you play that close together like they do."Indiana has 27 wins and 11 defeats this season. The last time a team won the national championship with as many as 11 losses was Kansas in 1988. Maryland has a school record of 31 wins against only 4 losses.

He would keep his dirigible tied to a gas lamp post in front of his Parisapartment and during the day he'd fly to go shopping or to visit friends.2. Since his was the first public flight in the world, he was hailed as theinventor of the airplane all over Europe.3. But to bring up the Wright brothers with a Brazilian is bound to elicit anavalanche of arguments as to why their flight didn't count.4. His flight did meet the criteria: He took off unassisted, publicly flew apredetermined length and then landed safely.5. By the time the Brazilian got around to his maiden flight the Wrightbrothers had already flown numerous times, including one flight inwhich they flew 39 kilometers.Ask anyone in Brazil who invented the airplane, and they will say Alberto Santos-Dumont, a bon vivant as well-known for his aerial prowess as he was for his dandyish* dress and place in the high-society life of Belle Epoque Paris.As Paul Hoffman recounts in his biography Wings of Madness, the eccentric* Brazilian was the only person in his day to own a flying machine."He would keep his dirigible* tied to a gas lamp post in front of his Paris apartment at the Champs Elysees, and every night he would fly to Maxim's for dinner. During the day he'd fly to go shopping or to visit friends," Hoffman said.It was on November 12, 1906, when Santos-Dumont flew a kite-like contraption* with boxy wings called the 14-Bis some 220 meters on the outskirts of Paris. Since his was the first public flight in the world, he was hailed as the inventor of the airplane all over Europe.It was only later that Orville and Wilbur Wright proved they had beaten Santos-Dumont at Kitty Hawk, North Carolina, three years earlier.But to bring up the Wright brothers with a Brazilian is bound to elicit* anavalanche of arguments as to why their flight didn't count."It's one of the biggest frauds* in history," scoffs Wagner Diogo, a taxidriver in Rio de Janeiro."No one saw it, and they used a catapult* to launch the airplane."The debate centers on the definition of flight.Henrique Lins de Barros, a Brazilian physicist and Santos-Dumont expert, argues that the Wright brothers' flight did not fulfill the conditions that had been set up at the time to distinguish a true flight from a prolonged hop.Santos-Dumont's flight did meet the criteria: He took off unassisted, publicly flew a predetermined length and then landed safely."If we understand what the criteria were at the end of the 19th century, the Wright brothers simply did not fill any of the prerequisites," said Lins de Barros.Brazilians claim that the Wrights launched their Flyer in 1903 with a catapult or at an incline, disqualifying it from being a true airplane.Even Santos-Dumont experts like Lins de Barros concede* this is wrong. He says that the steady winds at Kitty Hawk were crucial for the Flyer's takeoff, disqualifying the flight because it probably could not lift off on its own.Peter Jakab, chairman of the aeronautics division at the US National Air and Space Museum in / Washington, says such claims are preposterous*.By the time Santos-Dumont got around to his maiden flight the Wrightbrothers had already flown numerous times, including one flight in which they flew 39 kilometers.Even in France the Wrights are considered to have flown beforeSantos-Dumont, says Claude Carlier, director of the French Center for the History of Aeronautics and Space.By rounding the Eiffel Tower in a motorized dirigible in .190 I,Santos-Dumont helped prove that air travel could be controlled.Exercise A Pre-listening QuestionAlberto Santos-Dumont was a wealthy Brazilian aviation pioneer who came to Paris, France, at the age of 18 to live and study. He attempted his first balloon ascent in 1897 and had his first successful ascent in 1898. He began to construct dirigible airships powered with gasoline-powered engines in 1898 and built and flew fourteen of the small dirigibles. In 1901, he flew his hydrogen-filled airship from St. Cloud, around the Eiffel Tower, and back to St. Cloud. It was the first such flight and won him the Deutsch Prize and a prize from the Brazilian government. In 1902, he attempted to cross the Mediterranean in an airship but crashed into the sea. In 1909, he produced his "Demoiselle" or "Grasshopper" monoplane, the precursor to the modern light plane.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

You know I was born in Lausanne*, Switzerland; myfather was Swiss-French Swiss and my mother was American,so, of course, we spoke both languages at home and I grew upbilingual. Then, of course, I learnt German at school - inSwitzerland that's normal. And because I was already fluent inEnglish, my second language at school was Italian. So I had areal head start (有利的开端)!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you? Suzanne: Urn, I was native speaker standard in French and English, but I'd become a bit rusty* in German and my Italian was onlyschool standard. I decided the best option was to study in theUK, and I did Hispanic Studies at university, studying Spanishand Portuguese, with some Italian, and living in Manchester.Then I went to live in Brazil for two years, teaching English. Interviewer: So by this time you must have been fluent in six languages? Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became prettygood!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to aninterpreters' school and then got a job in the United Nationswhen I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday,got a job and stayed for two years, which was when I learntJapanese.Interviewer: That's amazing! And now you're back at the United Nations?Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague - some in Prague, some in Austria andSwitzerland, and I took a "sabbatical*" to work in Japan. Theyneed people who can understand Japanese. But, yes, I've beenback with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese - it's so different from all the others.So I'll spend another two or three years here with the UNfull-time, during which time I hope to get a substantialpromotion, then I think I'll go back and learn Korean, orperhaps Chinese, and Thai - I'd love to learn Thai. And then,perhaps an Indian language. Whatever, I want to be fluent inanother three or four languages before 45.ExerciseDirections: Listen to the dialogue and decide whether the following statements are true (T) or false (F).l.T 2.F 3.F 4.F 5.T 6.F 7.T 8.T 9.

FPart 2 PassageThe Clyde RiverRunning through one of Britain's biggest manufacturing centers, Glasgow, the Clyde River* was poisoned for more than a century bythe fetid* byproducts of industry.The waterway bore the brunt of(首当其冲)Glasgow's economic success during the Industrial Revolution and beyond, as pollution and chemicals destroyed its fish and wildlife populations and brewed smells whose memory still makes residents wince*. Now, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a riverthat was once one of Britain's filthiest.The Clyde River Foundation surveyed fish populations last autumnat 69 sites in the Clyde and its tributaries, and found salmon in sevenof the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last year's survey was the first to show they've come back in healthy numbers.Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are pictured on its official coat of arms.The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system inrecent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the Industrial Revolution that began in the late 1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles andchemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation and rough streets.

He says the nine chemicals that have joined the list of Persistent Organic Pollutants, or POPS, are extremely harmful to the environment and to health.The newly targeted chemicals include products that are widely used in pesticides and flame-retardants, and in a number of other commercial uses, such as a treatment for head lice.These nine toxic chemicals will join the Stockholm Convention's original list of 12 Persistent Organic Pollutants, referred to as the "dirty dozen."The pollutants are especially dangerous because they cross boundaries and travel long distances, from the Equator to the Arctic. They persist in the atmosphere and take many years, often decades, to degrade into less dangerous forms.They pose great risks to the environment and human health, especially to young people, farmers, pregnant women and the unborn.Exercise A Directions: Listen to the news item and complete the summary.This news item is about a ban of nine of the world’s most hazardous chemicals.Exercise BDirections: Listen to the news again and complete the followingpassage.UN environment Program Executive welcomed the agreement to ban the production of nine of the world’s most hazardous chemicals that are extremely harmful to the environment and to health.

A major conference in Copenhagen at the end of the year will focus on ways to mitigate the worst affects of global warming.WMO Secretary-General Michel Jarraud (世界气象组织秘书长贾侯)says countries must have the tools to adapt to a changing climate. They must be able to respond to a world that is likely to experience more extreme weather events, such as floods and hurricanes.Jarraud notes farmers in certain parts of the world will have to adapt to a dryer climate. He says they might have to modify irrigation systems or consider growing crops that do not require much rain.He says global warming is likely to increase the intensity and frequency of extreme weather events. Therefore, better and more timely information on these phenomena are essential to make decisions on climate variability and change. To do this, he says, weather observation networks must be strengthened.The WMO chief says climate change is a global problem. And, everyone needs everyone else to solve this problem. He says even the biggest, richest countries cannot do it alone.

An unexpected discoveryat the southern end of the reef has provided some rare good news for researchers.Researchers found that coral in the Keppel Islands off Queensland, which was damaged by bleaching in 2006 and then smothered by seaweed that overgrew the reef, has managed to repair itself.Experts say to see reefs bounce back from mass coral bleaching in less than a decade is highly unusual.Like other coral systems, the Great Barrier Reef is facing a range of environmental threats. Scientists say their capacity to recovery from damage inflicted by warmer waters, for example, will be critical to its future health.The Great Barrier Reef is one of Australia's premier tourist attractions.

Ban Ki-moon has said it was the biggest climate change demonstration ever attempted. Mr. Ban urged people everywhere to pressure their governments to take decisive action to cut carbon pollution.Organizers are hoping that up to a billion people from small villages in Namibia to sprawling cities in Asia will participate in an international effort to cut greenhouse gas emissions, which many scientists blame for a warming climate.One of the architects of Earth Hour, Andy Ridley from the conservation group World Wildlife Fund (WWF), says the current financial meltdown should not be used as an excuse to delay environmental reforms."The global economic crisis has proved that we are a global community, so when America goes bad, we all go bad and climate change is going to be on a scale that is way, way beyond our global economic crisis at the moment and we need to put in place the measures to a) slow that down and ideally halt it, b) be ready for economies thatwill have to change. So, the longer we procrastinate the more we pay the penalty so we need to move quickly," he said.Earth Hour was started by environmentalists in Sydney in 2007. It encourages households, businesses and governments to switch off all non-essential lights for 60 minutes in a show of unified concern for the health and future of the planet.In two years, the event has become a large global movement and its aim is to create an enormous wave of public pressure that will influence delegates at a meeting in Copenhagen later this year, which hopes to establish a new U.N. climate treaty.However, critics of Earth Hour have insisted it is simply a symbolic gesture that will not affect significant environmental change.The event will officially begin on the international dateline in the remote Chatham Islands southeast of New Zealand and will conclude in Hawaii.Exercise A: Directions: Listen to the news report and complete the summary.This news report is about a global event known as Earth Hour.Exercise BDirections: Listen to the news again and complete the following sentences.1.Scotland's Edinburgh Castle, the Bird's Nest stadium in Beijing andthe pyramids in Egypt will join the Sydney Opera House in d imming their lights as part of Earth Hour.2.Ban Ki-moon has said it was the biggest climate changedemonstration ever attempted.anizers are hoping that up to a billion people will participate in aninternational effort to cut greenhouse gas emissions, which many scientists blame for a warming climate.4.Andy Ridley, One of the architects of Earth Hour, says the currentfinancial meltdown should not be used as an excuse to delay environmental reforms.5.In two years, the event has become a large global movement and itsaim is to create an enormous wave of public pressure that will influence delegates at a meeting in Copenhagen later this year.Part 2 PassageLab produces shape-shifting fruits and vegetables Many fruits and vegetables we know almost as much by their shape as by their color or taste. Bananas are long and curved. Onions are round. But what if you could alter the familiar shape? Would a square tomato still be a tomato?Scientists are learning how to change the shape of fruits and vegetables so they can be harvested or processed more efficiently, or maybe just to reduce waste in the kitchen. It can be done to some extentwith traditional hybrid techniques. And as we hear from reporter Julie Grant, it can also be done by flipping a genetic switch.Ester van der Knaap steps gingerly around the greenhouse. We're at the Ohio State Agricultural Research and Development Center in Wooster. Van Der Knaap points out short, round tomatoes - and some odd-looking long, thin ones.V AN DER KNAAP: "That's one gene. One gene can make that difference."Van der Knaap's team discovered that gene and isolated it. They call it the SUN gene. And they've been able to clone it in tomatoes.Van der Knaap's research could lead to square-shapes - something she thinks the tomato industry might like. Square tomatoes fit into packages better. And, overall, square tomatoes might be easier to work with than the common round tomatoes.So far money for her research has come from the National Science Foundation - not big ag.Designer fruit shapes are gaining popularity.People have been cross-breeding tomatoes to make the shapes they want for a long time. But this is not the same thing.Dick Alford is a chef and professor of hospitality management at the University of Akron [Ohio].The difference between what his brother and lots of other folks havebeen doing and what van der Knaap is doing is the difference between cross-breeding and locating a specific gene that affects the shape of tomatoes.Chef Alford watches students as they cut yellow crookneck squash and carrots.They're trying to make uniform, symmetrical shapes out of curvy and pointed vegetables.

If you could get a tomato as long as a cucumber, where you could get 20 or 30 slices out of them, it would be great."In a country that loves hamburgers, Van der Knaap has heard that request before. But the long, thin tomato hasn't worked out just yet. She says there's more genetics to be studied.“Once we know all the genes responsible for making different shapes in tomatoes”, Van der Knaap says, “ we'll have a better idea of what controls the shape of other crops, such peppers, cucumbers and gourds.

Thus Social Security is a logical place to start answering the question: Can we afford to continue this trend of retiring ever earlier and living longer?The Social Security Administration projected income and expense for the Social Security fund from 2000 to 2050. The figures for both income-tax revenues and benefits paid out are sobering*. It highlights the coming deficits in a system on which so many Americans depend for at least a part of their livelihood during retirement.The gap between revenue and expense arises because of demographic shifts. The aging of the Baby Boomers and life-extending medical advances combine to create an imbalance in the Social Security system as designed.The system was established in 1935 and was intended as an insurance policy against a poverty-ridden old age, a not uncommon fate for the elderly during the first decades of the 20th century.The Social Security system has been expanded many times since its inception*. It now covers workers, disabled persons, and the dependents of each. The system also adjusts benefits for inflation annually.In the 1930s, life expectancy in the US was 59.7 years; many people never reached the age of retirement. In 2001, life expectancy was 77.6 years; most people today live for quite a while on Golden Pond*. We're living longer and drawing from the Social Security fund for more years with each passing generation. The declining age of retirement only exacerbates* this trend.In simple terms, if the number of those paying into the fund drops as the number of those drawing from it rises, an imbalance is sure to develop in the future.Barring any restructuring of the system beforehand, Social Security expenses will exceed revenues in the year 2015. At that point the system will begin to use reserves to meet its obligations. According to the Social Security Administration estimates, these reserves will carry the system through the mid-2030s. At that point, if not sooner, one of two things will need to be done: (1) The Social Security tax rate willneed to be increased, or (2) Benefits paid out wij1 need to be reduced. The second solution may involve extending the retirement age to 70 or an even older age. Since none of these options is politically palatable (the elderly have the highest voting rate), it remains to be seen which will be implemented - most likely some combination of the two.Since 3 out of every 10 Americans aged 65 or older depend on Social Security payments for 90% or more of their income (and 3 out of 5 depend on Social Security for 50% or more of their income) we must ask an important question: Are those of us now in our 30s and 40s planning on an alternative or supplemental retirement income?A: Pre-listening QuestionActually, it is a government scheme that provides economic assistance to those people faced with sickness, unemployment, maternity and retirement, etc. In this case, the cost is paid entirely out of taxation. If the cost is met wholly or partly from contributions paid by employers to the state, the scheme is usually called national insurance.B: Sentence DictationDirections: Listen to some sentences and write them down.

Last month in London, its leaders pledged $1 trillion to the IMF for loans and other assistance to help cushion the developing world from the effects of the global financial crisisBut some questions remain. Activists say, for example, that the G-20 promised $100 billion for multi-lateral institutions like the African and Asian Development Banks, but did not specify where the money would come from.They also want clarification on how proposals made by the G-20 would work. One is the issuing of $250 billion worth of the IMF reserve currency, called Special Drawing Rights, or SDRs, to nations needing funding against the effects of the global financial downturn. It is estimated that nearly $19 billion would go to low income countries under the plan and $60 billion to middle income countries like Mexico and Brazil.SDRs, which are worth about $1.50 can be exchanged for the leading currencies, including the dollar, the euro and the yen.The IMF would distribute SDRs to states according to the size of their voting shares within the institution.This news item is about the G-20’s financing aid for developing countries and activists’ doubt.B: Directions: Listen to the news again and complete the following passage.Activists say that the G-20promised $100 billion for institutions like the African and Asian Development Banks, but did not specify where the money would come from.Also they want to know how proposals made by the G-20 would work.

Central banks and governments fought back with massive cash injections, financial rescue packages and stimulus programs, but success in containing the crisis was far from assured.The global economy is expected to show a 1.1 percent drop in output for 2009, following a five percent expansion in 2007 and three percent growth in 2008.The past year has seen sharp spikes in unemployment, which peaked at 10.2 percent in the United States, 9.8 percent in Europe, 9 percent in Brazil and 5.7 percent in Japan.But a turnaround is underway, according to U.S. Treasury Secretary Timothy Geithner“The U.S. economy and the world economy a re now growing again. Businesses are starting to invest again, consumers are now spending, business and consumer confidence has improved, global trade is now expanding at an encouraging pace."But analysts warn that perils remain, and badly needed financial reforms in the United States and elsewhere have yet to be implementedPolicymakers must also decide when to wind down unprecedented levels of government stimulus and financial support. Those measures were deemed necessary in the face of an economic crisis, but can spark inflation if sustained for too long.The global economic downturn struck advanced industrialized nations particularly hard, providing an opening for rising economic powers like India and China to shine on the world stage.For many nations, the passing of the financial crisis means attention must be refocused on long-term problems that preceded the global recession. In the United States, massive government debt continues to grow at a time when an aging population is placing ever-greater demands on social welfare programs.In much of the developing world, such as in Kenya, other challenges must be tackled.Unlike in past economic rebounds, the United States is not in a position to drive global growth.Analysts say global economic growth will likely be powered by rapid expansion in countries like China and India, with contributions also coming from lesser developed nations.A: Directions: Listen to the news item and complete the summary.This news item is about the global economic upturn after the financial crisis.B: Directions: Listen to the dialogue and decide whether the following statements are true (T) or false (F).

His landmark book on evolution, On the Origin of Species, was published 150 years ago, and it's still considered perhaps the most important science book ever.In his book, Darwin described the idea of natural selection - species change and evolve, and organisms with characteristics more suitable to survival are more likely to reproduce. His ideas upended a 19th century world where most people believed that plants and animals always had their present form, and always would.His theory of evolution, as it's sometimes called, itself evolved over more than two decades, beginning with a five-year sea voyage aboard a British survey ship called the Beagle, where he served as naturalist, collecting specimens and observing exotic plants and animals.To get a larger picture of Charles Darwin the man and scientist, we're joined by an anthropologist who has written about Darwin and natural selection. We reached Mr. Milner at his home in New York.Charles Darwin was the son of two generations of English country physicians. He was born a naturalist, he said. When he was a little kid he loved poking under rocks, looking for fossils and bird's nests, making collections. His father shipped him off to medical school when he was 16 to be a doctor, like the rest of his family. But he couldn't stand the sight of blood.So then his father said, why don't you be a clergyman? So he was studying at Cambridge to be a churchman. But he could not get rid of this love he had for nature and trying to understand the birds and the beasts. And so when an offer came through one of his professors to be the ship's naturalist on a surveying ship, H.M.S. Beagle, that was going to do a five-year voyage around the world, he got permission to go, and he said, that was the start of my real life, that was the start of my real education.“So he sailed on the Beagle, which skirted around the coast of South America among other places in its journey over five years starting in 1831, and was there someplace along the line a "eureka moment" for Charles Darwin?”“Yeah, he had a eureka moment, but it had nothing to do with evolution.”“What was it that he saw during his voyage on the Beagle that firmed up for him the concept of natural selection?”“Well, Darwin, first of all, he was a collector on that ship. He collected thousands of specimens of rocks, fossils, insects, and birds. And he started to see patterns. He began to get the idea that all of life is related, and this is probably even more important than the idea of natural selection. The great tree of life. Darwin saw that we're all netted together, all living things are our cousins, and that's the foundation of evolutionary biology with or without natural selection.“Well, it's a pretty radical concept.”A: pre-listeningCharles Darwin (12 February 1809-19 April 1882) was an English naturalist who established that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a process that he called natural selection. He published his theory with compelling evidence for evolution in his 1859 book on the origin of species. The scientific community and much of the general public came to accept evolution as a fact in his lifetime, but it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed that natural selection was the basic mechanism of evolution. In modified form, Darwin’s scientific discovery is the unifying theory of the life sciences, explaining the diversity of life. B: sentence Dictation1. His ideas upended a 19th century world where most people believed that plants and animals always had their present form, and always would.2. His theory of evolution, as it's sometimes called, itself evolved over more thantwo decades, beginning with a five-year sea voyage aboard a British survey ship.3. So he was studying at Cambridge to be a churchman. But he could not get rid of this love he had for nature and trying to understand the birds and the beasts.4. When an offer came through one of his professors to be the ship's naturalist ona surveying ship, H.M.S. Beagle, that was going to do a five-year voyage around the world, he got permission to go.5.

You know I was born in Lausanne*, Switzerland; myfather was Swiss-French Swiss and my mother was American,so, of course, we spoke both languages at home and I grew upbilingual. Then, of course, I learnt German at school - inSwitzerland that's normal. And because I was already fluent inEnglish, my second language at school was Italian. So I had areal head start (有利的开端)!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you? Suzanne: Urn, I was native speaker standard in French and English, butI'd become a bit rusty* in German and my Italian was onlyschool standard. I decided the best option was to study in theUK, and I did Hispanic Studies at university, studying Spanishand Portuguese, with some Italian, and living in Manchester.Then I went to live in Brazil for two years, teaching English. Interviewer: So by this time you must have been fluent in six languages? Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became prettygood!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to aninterpreters' school and then got a job in the United Nationswhen I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday,got a job and stayed for two years, which was when I learntJapanese.Interviewer: That's amazing! And now you're back at the United Nations? Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague - some in Prague, some in Austria andSwitzerland, and I took a "sabbatical*" to work in Japan. Theyneed people who can understand Japanese. But, yes, I've beenback with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese - it's so different from all the others.So I'll spend another two or three years here with the UNfull-time, during which time I hope to get a substantialpromotion, then I think I'll go back and learn Korean, orperhaps Chinese, and Thai - I'd love to learn Thai. And then,perhaps an Indian language.

Now, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a riverthat was once one of Britain's filthiest.The Clyde River Foundation surveyed fish populations last autumnat 69 sites in the Clyde and its tributaries, and found salmon in sevenof the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last year's survey was the first to show they've come back in healthy numbers.Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are picturedon its official coat of arms.The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the Industrial Revolution that began in the late1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation and rough streets. More recently, its art museums and nightlife have helped drive an economic comeback that has turned the city into a popular tourist destination.Exercise A Pre-listening QuestionRivers are important to humans because they supply fresh drinking water, serve as home for important fishes, and provide transportation routes.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

An unexpected discovery at the southern end of the reef has provided some rare good news for researchers.Researchers found that coral in the Keppel Islands off Queensland, which was damaged by bleaching in 2006 and then smothered by seaweed that overgrew the reef, has managed to repair itself.Experts say to see reefs bounce back from mass coral bleaching in less than a decade is highly unusual.Like other coral systems, the Great Barrier Reef is facing a range ofenvironmental threats. Scientists say their capacity to recovery from damage inflicted by warmer waters, for example, will be critical to its future health.The Great Barrier Reef is one of Australia's premier tourist attractions.

Ban Ki-moon has said it was the biggest climate change demonstration ever attempted. Mr. Ban urged people everywhere to pressure their governments to take decisive action to cut carbon pollution.Organizers are hoping that up to a billion people from small villages in Namibia to sprawling cities in Asia will participate in an international effort to cut greenhouse gas emissions, which many scientists blame for a warming climate.One of the architects of Earth Hour, Andy Ridley from the conservation group World Wildlife Fund (WWF), says the current financial meltdown should not be used as an excuse to delay environmental reforms."The global economic crisis has proved that we are a global community, so when America goes bad, we all go bad and climate change is going to be on a scale that is way, way beyond our global economic crisis at the moment and we need to put in place the measures to a) slow that down and ideally halt it, b) be ready for economies that will have to change. So, the longer we procrastinate the more we pay the penalty so we need to move quickly," he said.Earth Hour was started by environmentalists in Sydney in 2007. It encourages households, businesses and governments to switch off all non-essential lights for 60 minutes in a show of unified concern for thehealth and future of the planet.In two years, the event has become a large global movement and its aim is to create an enormous wave of public pressure that will influence delegates at a meeting in Copenhagen later this year, which hopes to establish a new U.N. climate treaty.However, critics of Earth Hour have insisted it is simply a symbolic gesture that will not affect significant environmental change.The event will officially begin on the international dateline in the remote Chatham Islands southeast of New Zealand and will conclude in Hawaii.Exercise A: Directions: Listen to the news report and complete the summary.This news report is about a global event known as Earth Hour.Exercise BDirections: Listen to the news again and complete the following sentences.1.Scotland's Edinburgh Castle, the Bird's Nest stadium in Beijing andthe pyramids in Egypt will join the Sydney Opera House in d imming their lights as part of Earth Hour.2.Ban Ki-moon has said it was the biggest climate changedemonstration ever attempted.anizers are hoping that up to a billion people will participate in aninternational effort to cut greenhouse gas emissions, which many scientists blame for a warming climate.4.Andy Ridley, One of the architects of Earth Hour, says the currentfinancial meltdown should not be used as an excuse to delay environmental reforms.5.In two years, the event has become a large global movement and itsaim is to create an enormous wave of public pressure that will influence delegates at a meeting in Copenhagen later this year.Part 2 PassageLab produces shape-shifting fruits and vegetables Many fruits and vegetables we know almost as much by their shape as by their color or taste. Bananas are long and curved. Onions are round. But what if you could alter the familiar shape? Would a square tomato still be a tomato?Scientists are learning how to change the shape of fruits and vegetables so they can be harvested or processed more efficiently, or maybe just to reduce waste in the kitchen. It can be done to some extent with traditional hybrid techniques. And as we hear from reporter Julie Grant, it can also be done by flipping a genetic switch.Ester van der Knaap steps gingerly around the greenhouse.

But the long, thin tomato hasn't worked out just yet. She says there's more genetics to be studied.“Once we know all the genes responsible for making different shapes in tomatoes”, Van der Knaap says, “ we'll have a better idea of what controls the shape of other crops, such peppers, cucumbers and gourds.

Among the first inhabitants of Alaska and Canada were the Eskimos. They lived along the coasts and rivers of the Bering Sea and the Arctic Ocean. They fished, hunted and lived in small earth shelters and igloos to protect themselves from the cold. They used trained huskies to draw their sleds across the ice.Eskimo igloos are made from snow blocks built around skin tents. Inside they are warm but they are smoky and smelly from burning blubber, the fat from whales and seals. However, nowadays most Eskimos live in modern houses.Exercise:1. D2. B3. A 6. B7. C8. D4. A5.

Three weeks later, it was still on the market. I became a busy housekeeper. Every room had to be kept tidy, and dishes had to be washed and put away when u sed. Then one day the doorbell rang unexpectedly at 8 a.m. Sleepily, I open ed the door and saw our agent standing there with a couple from New York.“They had no time to call,” he explained, “because the couple had to c atch a plane home.”The three people made their way past the dirty breakfast dishes on the k itchen table and into a bedroom with unmade beds. As I went into the bath room to comb my hair, I heard the man say something to his wife. Then th ey both laughed.Two days later, the agent phoned to tell me that the couple had bought the house. He also told me that the couple said to him: “That house has a warm feeling, just like ours.”Section Four: Supplementary ExercisePart 1—Listening ComprehensionPassage 1 Hotel Reservation TipsHere is how to help you find what you are looking for:As always, the earlier you make your booking the more chance you have of finding hotels with a wider range of rooms to choose from. There is also a chance of your getting a room that make your budget.The earlier you book your room, the more chance you have of finding available rooms. Booking early means you can get a better chance of finding the type of room you want. If you have a budget, booking early gives you the chance of finding what you want within it as you are given more options.The search database searches for your criteria using a city name, a 3-letter city code or a 3-letter airport code. DO not enter airport, state or country name.If you know the 3-letter code of the city you want to stay in or the 3-letter code of an airport located in the city you want to stay in, use it for the search. This reduces the chance of the search result giving you a list of cities with the same name or with names that sound like the specified name you search for. If you do not know the 3-letter code of the city or airport and wish to use it, you can obtain the code using our Decoder, the last column on the search result display List. From “Destination” tells you how far and towards which direction the hotel is located from your destination.Everyone makes spelling mistakes. Check that you have typed the correct spelling for your search. Also remember that we use the common names for locations. If unsure about which name you should use for a particular place, use the common, English name. If you still have problems, call us, or search using the Decoder.The cost for rooms displayed on the results page is the cheapest cost of the rooms per night in the corresponding hotel. Some hotels have separate weekend rates which can be cheaper or more expensive than the weekly rate.

The study is part of an attempt by the federal g overnment to help Americans lose weight. American health officials say tha t more than half of all adults in the United States weigh too much. They say these Americans are likely to develop serious health problems.Americans spend thousands of millions of dollars on books, pills and pr ograms to help them lose weight. However, many people do not know muc h about the health effects of weight loss diets.The Agriculture Department examined earlier scientific studies of popul ar diets. The new government report found that many popular diets can he lp people lose weight. However, it said losing weight is not the same as prev enting weight gain.The report said that traditional diets may be the best way to lose weight and keep the weight off. These diets include eating foods moderated in fats and high in carbohydrates. Foods high in carbohydrates include bread, corn , potatoes and rice.The report confirms that dieters can lose weight by limiting what they e at. It said any diet that limits food to about 1,500 calories a day produces we ight loss.The report says traditional weight loss programs have the best scientific evidence to support their health claims and rates of success. These program s suggest eating no more than thirty percent of calories as fat. They suggest limiting protein to about twenty percent. And, they say dieters should eat m ore fruits, vegetables and carbohydrates.The report adds that only a few diets help to lower blood pressure and harmful cholesterol levels. The traditional diets showed some of the best im provements in blood cholesterol levels and in blood sugar control.Several diet experts agreed with the new report’s findings. They said more studies are needed to measure the safety and effectiveness of different diets.The American government already has a list of dietary suggestions. It s ays the best way to control weight is to exercise and eat lots of whole grains, fruits and vegetables.Exercise:T, F, T, F, F, T, T, T, F, TPart 2-- Oral WorkFor many years, T-shirts were simple short-sleeved undershirts for men and boys.

One of the first men to produce designs for aircraft was Leonardo da Vinci, an Italian artist who lived in the fifteenth century. However, it was not until the eighteenth century that people began to fly, or perhaps it would be better to say float, across the countryside in balloons. The first hot-air balloon was made in April 1783 by the Montgolfier brothers in France.In the following years many flights were made by balloon. Some of the flights were for pleasure and others were for delivering mail and for military purposes, such as observation and even bombing. However, in the late nineteenth century, airships superseded balloons as a form of transport.Airships came after balloons. The first powered and manned flight was made by a Frenchman, Giffard, in September 1852. His airship, powered by steam, traveled twenty-seven kilometers from Paris to Trappes at a speed of eight kilometers per hour. However the days of the airship were numbered as the aero plane became increasingly safe and popular.ExerciseDirections: Listen to the passage and write down the gist and the key words that help you decide.1.This passage is about the early history of flying.2.The key words are designs, an Italian artist, fifteenth century, eighteenthcentury, fly, float, balloons, hot-air balloon, April 1783, airships, September 1852, aeroplane.Section Two Listening ComprehensionPart 1 DialogueBuying a CarA: Good morning, can I help you?B: Yes, I'm interested in buying a car.A: Have you anything in mind?B: Not really.A: What price are youthinking of?B: Not more than £13,500.A: Let's see now ...

The starts were all made from a point on the level sand about 200 feet west of our camp, which is located a quarter of a mile north of the Kill Devil sand hill, in Dare County, North Carolina.The wind at the time of the flights had a velocity* of 27 miles an hour at 10a.m., and 24 miles an hour at noon, as recorded by the anemometer* at the Kitty Hawk Weather Bureau Station.The flights were directly against the wind. Each time the machine started from the level ground by its own power alone with no assistance from gravity or any other source whatever.After a run of about 40 feet along a monorail* track, which held the machine 8 inches (20 centimeters) from the ground, it rose from the track and under the direction of the operator climbed upward on an inclined course till a height of 8 or 10 feet from the ground was reached, after which the course was kept as near horizontal as the wind gusts and the limited skill of the operator would permit.Into the teeth of a December gale the "Flyer" made its way forward with a speed of 10 miles an hour over the ground and 30 to 35 miles an hour through the air.It had previously been decided that for reasons of personal safety these first trials should be made as close to the ground as possible. The height chosen was sufficient for maneuvering* in so gusty a wind and with no previous acquaintance with the conduct of the machine and its controlling mechanisms. Consequently the first flight was short.The succeeding flights rapidly increased in length and at the fourth trial a flight of 59 seconds was made, in which time the machine flew a little more than half a mile through the air and a distance of 852 feet over the ground.The landing was due to a slight error of judgment on the part of the aviator. After passing over a little hummock* of sand, in attempting to bring the machine down to the desired height, the operator turned the rudder* too far, and the machine turned downward more quickly than had been expected. The reverse movement of the rudder was a fraction of a second too late to prevent the machine from touching the ground and thus ending the flight.As winter was already well set in, we should have postponed the trials to a more favorable season, but we were determined to know whether the machine possessed sufficient power to fly, sufficient strength to withstand the shocks of landings and sufficient capacity of control to make flight safe in boisterous* winds, as well as in calm air.Exercise A Pre-listening QuestionOrville Wright (1871-1948), American aeronautical engineer, famous for his role in the first controlled, powered flight in a heavier-than-air machine and for his participation in the design of the aircraft's control system. Wright worked closely with his brother, Wilbur Wright (1867-1912), American aeronautical engineer, in designing and flying the Wright airplane.During the years 1900, 1901, 1902, and 1903, the two brothers developed the first effective airplane. At Kitty Hawk, North Carolina, on December 17, 1903, Orville Wright made the first successful flight of a piloted, heavier-than-air, self-propelled craft, called the Flyer. The third Flyer, which the Wrightsconstructed in 1905, was the world's first fully practical airplane. It could bank, turn, circle, make figure eights, and remain in the air for as long as the fuel lasted, up to half an hour on occasion.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

He would keep his dirigible tied to a gas lamp post in front of his Parisapartment and during the day he'd fly to go shopping or to visit friends.2. Since his was the first public flight in the world, he was hailed as theinventor of the airplane all over Europe.3. But to bring up the Wright brothers with a Brazilian is bound to elicit anavalanche of arguments as to why their flight didn't count.4. His flight did meet the criteria: He took off unassisted, publicly flew apredetermined length and then landed safely.5. By the time the Brazilian got around to his maiden flight the Wrightbrothers had already flown numerous times, including one flight inwhich they flew 39 kilometers.Ask anyone in Brazil who invented the airplane, and they will say Alberto Santos-Dumont, a bon vivant as well-known for his aerial prowess as he was for his dandyish* dress and place in the high-society life of Belle Epoque Paris.As Paul Hoffman recounts in his biography Wings of Madness, the eccentric* Brazilian was the only person in his day to own a flying machine."He would keep his dirigible* tied to a gas lamp post in front of his Paris apartment at the Champs Elysees, and every night he would fly to Maxim's for dinner. During the day he'd fly to go shopping or to visit friends," Hoffman said.It was on November 12, 1906, when Santos-Dumont flew a kite-like contraption* with boxy wings called the 14-Bis some 220 meters on the outskirts of Paris. Since his was the first public flight in the world, he was hailed as the inventor of the airplane all over Europe.It was only later that Orville and Wilbur Wright proved they had beaten Santos-Dumont at Kitty Hawk, North Carolina, three years earlier.But to bring up the Wright brothers with a Brazilian is bound to elicit* anavalanche of arguments as to why their flight didn't count."It's one of the biggest frauds* in history," scoffs Wagner Diogo, a taxidriver in Rio de Janeiro."No one saw it, and they used a catapult* to launch the airplane."The debate centers on the definition of flight.Henrique Lins de Barros, a Brazilian physicist and Santos-Dumont expert, argues that the Wright brothers' flight did not fulfill the conditions that had been set up at the time to distinguish a true flight from a prolonged hop.Santos-Dumont's flight did meet the criteria: He took off unassisted, publicly flew a predetermined length and then landed safely."If we understand what the criteria were at the end of the 19th century, the Wright brothers simply did not fill any of the prerequisites," said Lins de Barros.Brazilians claim that the Wrights launched their Flyer in 1903 with a catapult or at an incline, disqualifying it from being a true airplane.Even Santos-Dumont experts like Lins de Barros concede* this is wrong. He says that the steady winds at Kitty Hawk were crucial for the Flyer's takeoff, disqualifying the flight because it probably could not lift off on its own.Peter Jakab, chairman of the aeronautics division at the US National Air and Space Museum in / Washington, says such claims are preposterous*.By the time Santos-Dumont got around to his maiden flight the Wrightbrothers had already flown numerous times, including one flight in which they flew 39 kilometers.Even in France the Wrights are considered to have flown beforeSantos-Dumont, says Claude Carlier, director of the French Center for the History of Aeronautics and Space.By rounding the Eiffel Tower in a motorized dirigible in .190 I,Santos-Dumont helped prove that air travel could be controlled.Exercise A Pre-listening QuestionAlberto Santos-Dumont was a wealthy Brazilian aviation pioneer who came to Paris, France, at the age of 18 to live and study. He attempted his first balloon ascent in 1897 and had his first successful ascent in 1898. He began to construct dirigible airships powered with gasoline-powered engines in 1898 and built and flew fourteen of the small dirigibles. In 1901, he flew his hydrogen-filled airship from St. Cloud, around the Eiffel Tower, and back to St. Cloud. It was the first such flight and won him the Deutsch Prize and a prize from the Brazilian government. In 1902, he attempted to cross the Mediterranean in an airship but crashed into the sea. In 1909, he produced his "Demoiselle" or "Grasshopper" monoplane, the precursor to the modern light plane.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

You know I was born in Lausanne*, Switzerland; myfather was Swiss-French Swiss and my mother was American,so, of course, we spoke both languages at home and I grew upbilingual. Then, of course, I learnt German at school - inSwitzerland that's normal. And because I was already fluent inEnglish, my second language at school was Italian. So I had areal head start (有利的开端)!Interviewer: So that's ... one, two, three, four - you had learnt four languages by the time you left school? How fluent were you? Suzanne: Urn, I was native speaker standard in French and English, butI'd become a bit rusty* in German and my Italian was onlyschool standard. I decided the best option was to study in theUK, and I did Hispanic Studies at university, studying Spanishand Portuguese, with some Italian, and living in Manchester.Then I went to live in Brazil for two years, teaching English. Interviewer: So by this time you must have been fluent in six languages? Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became prettygood!Interviewer: And then what did you do?Suzanne: When I was 25 I came back to Switzerland, went to aninterpreters' school and then got a job in the United Nationswhen I was 28.Interviewer: And you've been there ever since?Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987and that was where I learnt Czech.Interviewer: And the eighth language?Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday,got a job and stayed for two years, which was when I learntJapanese.Interviewer: That's amazing! And now you're back at the United Nations? Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague - some in Prague, some in Austria andSwitzerland, and I took a "sabbatical*" to work in Japan. Theyneed people who can understand Japanese. But, yes, I've beenback with them full-time for two years now.Interviewer: And your plans for the future?Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese - it's so different from all the others.So I'll spend another two or three years here with the UNfull-time, during which time I hope to get a substantialpromotion, then I think I'll go back and learn Korean, orperhaps Chinese, and Thai - I'd love to learn Thai. And then,perhaps an Indian language. Whatever, I want to be fluent inanother three or four languages before 45.ExerciseDirections: Listen to the dialogue and decide whether the following statements are true (T) or false (F).l.T 2.F 3.F 4.F 5.T 6.F 7.T 8.T 9.

Now, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life.For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a riverthat was once one of Britain's filthiest.The Clyde River Foundation surveyed fish populations last autumnat 69 sites in the Clyde and its tributaries, and found salmon in sevenof the nine major tributaries.The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last year's survey was the first to show they've come back in healthy numbers.Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are picturedon its official coat of arms.The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive.The decline of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution.The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air.With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlantic, the Clyde comeback is a rare bit of good news for Scotland's fish lovers.Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history.The river's depth and navigability helped make Glasgow an important center for importing tobacco, sugar and cotton from the Americas starting in the 1600s. Later, during the Industrial Revolution that began in the late1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers.The mills and factories that lined the Clyde made steel, textiles and chemicals, tanned leather and even produced candy and brewed alcohol.When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation and rough streets. More recently, its art museums and nightlife have helped drive an economic comeback that has turned the city into a popular tourist destination.Exercise A Pre-listening QuestionRivers are important to humans because they supply fresh drinking water, serve as home for important fishes, and provide transportation routes.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

An unexpected discovery at the southern end of the reef has provided some rare good news for researchers.Researchers found that coral in the Keppel Islands off Queensland, which was damaged by bleaching in 2006 and then smothered by seaweed that overgrew the reef, has managed to repair itself.Experts say to see reefs bounce back from mass coral bleaching in less than a decade is highly unusual.Like other coral systems, the Great Barrier Reef is facing a range ofenvironmental threats. Scientists say their capacity to recovery from damage inflicted by warmer waters, for example, will be critical to its future health.The Great Barrier Reef is one of Australia's premier tourist attractions.

Ban Ki-moon has said it was the biggest climate change demonstration ever attempted. Mr. Ban urged people everywhere to pressure their governments to take decisive action to cut carbon pollution.Organizers are hoping that up to a billion people from small villages in Namibia to sprawling cities in Asia will participate in an international effort to cut greenhouse gas emissions, which many scientists blame for a warming climate.One of the architects of Earth Hour, Andy Ridley from the conservation group World Wildlife Fund (WWF), says the current financial meltdown should not be used as an excuse to delay environmental reforms."The global economic crisis has proved that we are a global community, so when America goes bad, we all go bad and climate change is going to be on a scale that is way, way beyond our global economic crisis at the moment and we need to put in place the measures to a) slow that down and ideally halt it, b) be ready for economies that will have to change. So, the longer we procrastinate the more we pay the penalty so we need to move quickly," he said.Earth Hour was started by environmentalists in Sydney in 2007. It encourages households, businesses and governments to switch off all non-essential lights for 60 minutes in a show of unified concern for thehealth and future of the planet.In two years, the event has become a large global movement and its aim is to create an enormous wave of public pressure that will influence delegates at a meeting in Copenhagen later this year, which hopes to establish a new U.N. climate treaty.However, critics of Earth Hour have insisted it is simply a symbolic gesture that will not affect significant environmental change.The event will officially begin on the international dateline in the remote Chatham Islands southeast of New Zealand and will conclude in Hawaii.Exercise A: Directions: Listen to the news report and complete the summary.This news report is about a global event known as Earth Hour.Exercise BDirections: Listen to the news again and complete the following sentences.1.Scotland's Edinburgh Castle, the Bird's Nest stadium in Beijing andthe pyramids in Egypt will join the Sydney Opera House in d imming their lights as part of Earth Hour.2.Ban Ki-moon has said it was the biggest climate changedemonstration ever attempted.anizers are hoping that up to a billion people will participate in aninternational effort to cut greenhouse gas emissions, which many scientists blame for a warming climate.4.Andy Ridley, One of the architects of Earth Hour, says the currentfinancial meltdown should not be used as an excuse to delay environmental reforms.5.In two years, the event has become a large global movement and itsaim is to create an enormous wave of public pressure that will influence delegates at a meeting in Copenhagen later this year.Part 2 PassageLab produces shape-shifting fruits and vegetables Many fruits and vegetables we know almost as much by their shape as by their color or taste. Bananas are long and curved. Onions are round. But what if you could alter the familiar shape? Would a square tomato still be a tomato?Scientists are learning how to change the shape of fruits and vegetables so they can be harvested or processed more efficiently, or maybe just to reduce waste in the kitchen. It can be done to some extent with traditional hybrid techniques. And as we hear from reporter Julie Grant, it can also be done by flipping a genetic switch.Ester van der Knaap steps gingerly around the greenhouse. We're at the Ohio State Agricultural Research and Development Center in Wooster.Van Der Knaap points out short, round tomatoes - and some odd-looking long, thin ones.V AN DER KNAAP: "That's one gene. One gene can make that difference."Van der Knaap's team discovered that gene and isolated it. They call it the SUN gene. And they've been able to clone it in tomatoes.Van der Knaap's research could lead to square-shapes - something she thinks the tomato industry might like. Square tomatoes fit into packages better. And, overall, square tomatoes might be easier to work with than the common round tomatoes.So far money for her research has come from the National Science Foundation - not big ag.Designer fruit shapes are gaining popularity.People have been cross-breeding tomatoes to make the shapes they want for a long time. But this is not the same thing.Dick Alford is a chef and professor of hospitality management at the University of Akron [Ohio].The difference between what his brother and lots of other folks have been doing and what van der Knaap is doing is the difference between cross-breeding and locating a specific gene that affects the shape of tomatoes.Chef Alford watches students as they cut yellow crookneck squashand carrots.They're trying to make uniform, symmetrical shapes out of curvy and pointed vegetables.

If you could get a tomato as long as a cucumber, where you could get 20 or 30 slices out of them, it would be great."In a country that loves hamburgers, Van der Knaap has heard that request before. But the long, thin tomato hasn't worked out just yet. She says there's more genetics to be studied.“Once we know all the genes responsible for making different shapes in tomatoes”, Van der Knaap says, “ we'll have a better idea of what controls the shape of other crops, such peppers, cucumbers and gourds.

One of the first men to produce designs for aircraft was Leonardo da Vinci, an Italian artist who lived in the fifteenth century. However, it was not until the eighteenth century that people began to fly, or perhaps it would be better to say float, across the countryside in balloons. The first hot-air balloon was made in April 1783 by the Montgolfier brothers in France.In the following years many flights were made by balloon. Some of the flights were for pleasure and others were for delivering mail and for military purposes, such as observation and even bombing. However, in the late nineteenth century, airships superseded balloons as a form of transport.Airships came after balloons. The first powered and manned flight was made by a Frenchman, Giffard, in September 1852. His airship, powered by steam, traveled twenty-seven kilometers from Paris to Trappes at a speed of eight kilometers per hour. However the days of the airship were numbered as the aero plane became increasingly safe and popular.ExerciseDirections: Listen to the passage and write down the gist and the key words that help you decide.1.This passage is about the early history of flying.2.The key words are designs, an Italian artist, fifteenth century, eighteenthcentury, fly, float, balloons, hot-air balloon, April 1783, airships, September 1852, aeroplane.Section Two Listening ComprehensionPart 1 DialogueBuying a CarA: Good morning, can I help you?B: Yes, I'm interested in buying a car.A: Have you anything in mind?B: Not really.A: What price are youthinking of?B: Not more than £13,500.A: Let's see now ...

The starts were all made from a point on the level sand about 200 feet west of our camp, which is located a quarter of a mile north of the Kill Devil sand hill, in Dare County, North Carolina.The wind at the time of the flights had a velocity* of 27 miles an hour at 10a.m., and 24 miles an hour at noon, as recorded by the anemometer* at the Kitty Hawk Weather Bureau Station.The flights were directly against the wind. Each time the machine started from the level ground by its own power alone with no assistance from gravity or any other source whatever.After a run of about 40 feet along a monorail* track, which held the machine 8 inches (20 centimeters) from the ground, it rose from the track and under the direction of the operator climbed upward on an inclined course till a height of 8 or 10 feet from the ground was reached, after which the course was kept as near horizontal as the wind gusts and the limited skill of the operator would permit.Into the teeth of a December gale the "Flyer" made its way forward with a speed of 10 miles an hour over the ground and 30 to 35 miles an hour through the air.It had previously been decided that for reasons of personal safety these first trials should be made as close to the ground as possible. The height chosen was sufficient for maneuvering* in so gusty a wind and with no previous acquaintance with the conduct of the machine and its controlling mechanisms. Consequently the first flight was short.The succeeding flights rapidly increased in length and at the fourth trial a flight of 59 seconds was made, in which time the machine flew a little more than half a mile through the air and a distance of 852 feet over the ground.The landing was due to a slight error of judgment on the part of the aviator. After passing over a little hummock* of sand, in attempting to bring the machine down to the desired height, the operator turned the rudder* too far, and the machine turned downward more quickly than had been expected. The reverse movement of the rudder was a fraction of a second too late to prevent the machine from touching the ground and thus ending the flight.As winter was already well set in, we should have postponed the trials to a more favorable season, but we were determined to know whether the machine possessed sufficient power to fly, sufficient strength to withstand the shocks of landings and sufficient capacity of control to make flight safe in boisterous* winds, as well as in calm air.Exercise A Pre-listening QuestionOrville Wright (1871-1948), American aeronautical engineer, famous for his role in the first controlled, powered flight in a heavier-than-air machine and for his participation in the design of the aircraft's control system. Wright worked closely with his brother, Wilbur Wright (1867-1912), American aeronautical engineer, in designing and flying the Wright airplane.During the years 1900, 1901, 1902, and 1903, the two brothers developed the first effective airplane. At Kitty Hawk, North Carolina, on December 17, 1903, Orville Wright made the first successful flight of a piloted, heavier-than-air, self-propelled craft, called the Flyer. The third Flyer, which the Wrightsconstructed in 1905, was the world's first fully practical airplane. It could bank, turn, circle, make figure eights, and remain in the air for as long as the fuel lasted, up to half an hour on occasion.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

To get here, the Maryland Terrapins had to beat three teams with great basketball traditions: Kentucky, Connecticut and Kansas.Now they face another, Indiana. while Maryland was one of the four top seeds in this 65-team tournament, the Indiana Hoosiers* were a fifth seed, and virtually no one expected them to reach the title game*. But they knocked off defending champion Duke in the third round, and in the semifinals they upset Oklahoma.Maryland coach Gary Williams knows it will take a solid effort to win. "Any team that's gotten to where Indiana has gotten, you don't look at their record. You look at how they're playing now, how they play. Any time a team plays team defense like they do, they have a chance to beat anybody. That's what concerns me the most, their ability to play together as a unit, because a lot of times you can play with anybody when you play that close together like they do."Indiana has 27 wins and 11 defeats this season. The last time a team won the national championship with as many as 11 losses was Kansas in 1988. Maryland has a school record of 31 wins against only 4 losses.

He would keep his dirigible tied to a gas lamp post in front of his Parisapartment and during the day he'd fly to go shopping or to visit friends.2. Since his was the first public flight in the world, he was hailed as theinventor of the airplane all over Europe.3. But to bring up the Wright brothers with a Brazilian is bound to elicit anavalanche of arguments as to why their flight didn't count.4. His flight did meet the criteria: He took off unassisted, publicly flew apredetermined length and then landed safely.5. By the time the Brazilian got around to his maiden flight the Wrightbrothers had already flown numerous times, including one flight inwhich they flew 39 kilometers.Ask anyone in Brazil who invented the airplane, and they will say Alberto Santos-Dumont, a bon vivant as well-known for his aerial prowess as he was for his dandyish* dress and place in the high-society life of Belle Epoque Paris.As Paul Hoffman recounts in his biography Wings of Madness, the eccentric* Brazilian was the only person in his day to own a flying machine."He would keep his dirigible* tied to a gas lamp post in front of his Paris apartment at the Champs Elysees, and every night he would fly to Maxim's for dinner. During the day he'd fly to go shopping or to visit friends," Hoffman said.It was on November 12, 1906, when Santos-Dumont flew a kite-like contraption* with boxy wings called the 14-Bis some 220 meters on the outskirts of Paris. Since his was the first public flight in the world, he was hailed as the inventor of the airplane all over Europe.It was only later that Orville and Wilbur Wright proved they had beaten Santos-Dumont at Kitty Hawk, North Carolina, three years earlier.But to bring up the Wright brothers with a Brazilian is bound to elicit* anavalanche of arguments as to why their flight didn't count."It's one of the biggest frauds* in history," scoffs Wagner Diogo, a taxidriver in Rio de Janeiro."No one saw it, and they used a catapult* to launch the airplane."The debate centers on the definition of flight.Henrique Lins de Barros, a Brazilian physicist and Santos-Dumont expert, argues that the Wright brothers' flight did not fulfill the conditions that had been set up at the time to distinguish a true flight from a prolonged hop.Santos-Dumont's flight did meet the criteria: He took off unassisted, publicly flew a predetermined length and then landed safely."If we understand what the criteria were at the end of the 19th century, the Wright brothers simply did not fill any of the prerequisites," said Lins de Barros.Brazilians claim that the Wrights launched their Flyer in 1903 with a catapult or at an incline, disqualifying it from being a true airplane.Even Santos-Dumont experts like Lins de Barros concede* this is wrong. He says that the steady winds at Kitty Hawk were crucial for the Flyer's takeoff, disqualifying the flight because it probably could not lift off on its own.Peter Jakab, chairman of the aeronautics division at the US National Air and Space Museum in / Washington, says such claims are preposterous*.By the time Santos-Dumont got around to his maiden flight the Wrightbrothers had already flown numerous times, including one flight in which they flew 39 kilometers.Even in France the Wrights are considered to have flown beforeSantos-Dumont, says Claude Carlier, director of the French Center for the History of Aeronautics and Space.By rounding the Eiffel Tower in a motorized dirigible in .190 I,Santos-Dumont helped prove that air travel could be controlled.Exercise A Pre-listening QuestionAlberto Santos-Dumont was a wealthy Brazilian aviation pioneer who came to Paris, France, at the age of 18 to live and study. He attempted his first balloon ascent in 1897 and had his first successful ascent in 1898. He began to construct dirigible airships powered with gasoline-powered engines in 1898 and built and flew fourteen of the small dirigibles. In 1901, he flew his hydrogen-filled airship from St. Cloud, around the Eiffel Tower, and back to St. Cloud. It was the first such flight and won him the Deutsch Prize and a prize from the Brazilian government. In 1902, he attempted to cross the Mediterranean in an airship but crashed into the sea. In 1909, he produced his "Demoiselle" or "Grasshopper" monoplane, the precursor to the modern light plane.Exercise B Sentence DictationDirections: Listen to some sentences and write them down.

No hard evidence exists to support that tale, but in any case, by the sixth Awards Presentation in 1934, a Hollywood columnist used the name in his column.3. Walt Disney was honored with one full-size and seven miniature statuettes on behalf of his animated feature Snow White and the Seven Dwarfs.4. If the statuettes don't meet strict quality control standards, they are immediately cut in half and melted down.5.The large boxes are shipped to the Academy offices via air express, with no identifiable markings.The Oscar statuette, designed by MGM's* chief art director Cedric Gibbons, depicts* a knight holding a crusader's* sword, standing on a reel of film with five spokes, signifying the original branches of the Academy: Actors, Writers, Directors, Producers, and Technicians.Born in 1928, years would pass before the Academy Award of Merit was officially named "Oscar". Industry insiders and members of the press called the award "the Academy statuette", "the golden trophy" or "the statue of merit". The entertainment trade paper, Weekly Variety, even attempted to popularize "the iron man". The term never stuck.A popular story has been that an Academy librarian and eventual executive director, Margaret Herrick, thought the statuette resembled her uncle Oscar and said so, and that as a result the Academy staff began referring to it as Oscar.No hard evidence exists to support that tale, but in any case, by the sixth Awards Presentation in 1934, Hollywood columnist Sidney Skolsky used the name in his column in reference to Katharine Hepburn's first Best Actress win. The Academy itself didn't use the nickname officially until 1939.Since its conception, the Oscar statuette has met exacting uniform standards - with a few notable exceptions. In the 1930s, juvenile players received miniature replicas* of the statuette。
