Some people are thinking about it. They are involved in a project to save objects in a container that is not to be opened until New Yearns Day 1,000 years form now・ The container is a time capsule.The idea for this time capsule came from the people at the New York Times newspaper. So it is called the Times capsule・ The papers and objects to be put in it are to help people in the year 3000 understand about life in the world today. First, a container was needed to keep the materials safe. So the newspaper invited 48 architects and designers from around the world to take part in a design competition. An architect from Spain Santiago Caltravo won. His winning design is a shiny steel container. It has one and one half cubic meters of space inside・ It is shaped like a flower with eight separate parts・ Mr. Caltravo says he wanted the container to be beautiful yet create a feeling of mystery. Some of the things that will be placed in the Times capsule have been chosen. They are being shown along with the Times capsule at the American Museum of Natural History in New York City.Among the objects arc six magazines published by the New York Times which described the last 1,000 years, a recording of the sounds of life in New York City made at 9:09 in the morning of the 9th day of the 9th month of 1999, pictures taken of what some people in New York were doing at that same time, a small container of fresh water from a river in Brazil, and an American military medal, a ceremonial chair from Zimbabwe, a beanie baby doll popular with collectors, Marlboro cigarettes・ Other things will be chosen to represent life at the present time. Visitors to the museum can use two computers to enter their own suggestions・ The objects chosen by a special committee will be placed in the capsule before it is closed in April.Then the large steel container will be moved to its permanent home outside the entrance of the Natural History Museum.Although the Times capsule is not to be opened for 1,000 years, it should not be forgotten. A guard will be paid to watch over it and remind people of why it is important. The creators of the project hope the guard duty will be passed on from person to person through the next ten centuries.Part III A1 ・ actions / present / responsibility recognize create/ imposed fate/ forces2.diagnosis and treatment textbooks interactive questions / alternative results/ affect3.brainwaves/ check out/ busy, tired brain activityscalp/ performing well too tired/ computer analysis monitorTape script:1.Your 21st centuryThe future will not determine itself. The future is determined by the actions of the present day. Edward Cornish, the editor of The Futurist magazine published by the World Future Society,says, “The responsibility we have for the future begins when we recognize that we ourselves create the future一that the future is not something imposed upon us by fate or other forces beyond our control/5 2.Your 21s, century doctorMore and more doctors will use computers for medical diagnosis and treatment.You will visit your doctor, and find that he uses a computer screen and visual infonnation about your condition instead of his textbooks・Computers in your home will enable you to answer interactive questions about your health and show the alternative results which will affect you if you act in a certain way.3 ・ Your 21st century brainYour brainwaves may be used to check out whether you are busy, tired, or doing your work properly.Psychologist Arthur F. Kramer, at the University of Illinois, tested volunteers working on arithmetic problems. He found that he could predict their performance from the strength of the brain's electrical activity. This is measured through the scalp.The future? Bosses could measure brain activity through the scalp and tell whether a worker is performing well, working hard, or too tired to do the job properly. Ongoing computer analysis could tell whether a worker, such as an air traffic controller, is seeing all the activity they have to monitor clearly eno ugh ・B・ forecast and assignment/ tourism 1.56 billion 1.18 billion 0.38 billion717 million 46% 397 million 25% 282 million18% 4.1% >5%Tape script:WTO long-term forecast tourism 2020 visionTourism 2020 Vision is the World Tourism Organization^ long-term forecast and assessment of the development of tourism up to the first 20 years of the new millcnnium.WTO's Tourism 2020 Vision forecasts that international arrivals are expected to reach over 1.56 billion by the year 2020.

One looks forward to the day when the motor-car has been replaced by some less dangerous means of transport.Item eightPetroleum has been important since ancient times・ In Latin, the name means "rock oil： Petroleum is a fossil fuel. The liquid comes from the remains of plants and animals that died millions of years ago. These remains were buried deep below levels of rock over time and under great pressure・ This geological process created complex molecules of hydrogen and carbon. Oil can also contain other elements. Crude oil, or unprocessed petroleum, is called sour when it contains a lot of sulfur, an impurity・ Sour crude requires more refining than sweet crude, which is often more valuable.Item nineIn September of 2000, world leaders set eight goals for bringing millions of people out of poverty.

Central Bank governors from more than a dozen countries have beenmeeting in Hong Kong today. One subject they likely discussed is the outlook for the global economy because of the U. S. slowdown and Japan's struggling recovery. Another topic they may have discussed is how to strengthen financial markets in emerging economies in Asia and elsewhere.2. A United Nations' report says the worldwide total of foreign investment grew by nearly 40% last year to more than 600 billion dollars. The report by the UN Conference on Trade and Development, UNCTAD says most of it took place between developed countries as big companies took one another over.3. The United States House of Representatives has approved a cut in income tax rates, the first part of a package of tax cutting measures put forward by President Bush. The income tax reductions will amount to nearly 1 trillion dollars over ten years.4. The world's largest maker of computer chips, Intel, has announced job cuts after a fall in demand for its products. Intel said it expected its revenue in the first quarter of this year to fall by a quarter than the same period last year. The California-based company plans to reduce its 85,000-strong work force by 5,000.5. The European Union has imposed further restrictions on the movement of live-stock after a case of foot-and-mouth disease was confirmed in France. The United States and Canada have issuedtemporary bans on the import of all animal produce from EU countries.

The South African surgeon has succeeded in transplanting tissues into the human brain in what is thought to be the first operation of its kind. The surgery was performed a week ago on a patient sufferingfrom Parkinson’s disease. A portion of the patient’s adrenal gland was implanted into a part of the patient’s brain, an operation which has previously been performed only on rats and monkeys. Approximately a third of all people develop cancer at one point in their lives. Chemotherapy has its limitations, but it is one of the major treatment options. Some American scientists have discovered they can increase the effectiveness of chemotherapy by inhibiting a natural defense mechanism employed by cancer cells.Glaucoma is responsible for blindness in an estimated 67 million people around the world. Until now, treatments have focused exclusively on the eyes. But that may change in the next few year, following the discovery that glaucoma involves the death of brain cells.New research shows that the simple act of writing down thoughts about a stressful event can help people with chronic illnesses improve their health. This is the first study to show that writing can result in clinically meaningful outcomes for chronically-ill patients. The study adds to the growing amount of scientific literature suggesting that meeting patient’s psychological needs produces physical health benefits.Traditional Chinese medicine says that good health is associated with the balance of Qi. Qi can be hindered or helped by yang and yin. According to traditional theory, the goal of acupuncture is to promote the flow of qi by keeping yin and yang in balance ---- and this is done byinserting needles at various points along primary channels and meridians that crisscross the body. One of the key benefits of acupuncture is that it has few, if any, side-effects; and that when used with standard drug treatment --- in anesthesia, for example --- it allows physicians to cut back on medication, delivering the same level of benefit with fewer negative effects/Bgene / instructions / characteristic / DNA / inserts / another / organism / genetically modified organism / genetic engineeringartificial fertilizers / pest control / food / farming / artificial fertilizers / halfGenetic material / unrelated / another species / animal /plant / going acrossanimals / cows, goats and pigs / genetically changed / pharmaceutical drugs / farmingNovel / 1797-1851/ scientist / subhuman / destroying / creation that ends up destroying the creator.Unit 6Part I Warming upA1.1.

But a research team has found a new use for it. A bulletproof vest made of silk was put to the test at a shooting range in Thailand. After several rounds of gunfire, the vest was examined. The bullets were stuck in the first layer of fifteen pieces of silk. A member of the research team says while silk threads may be soft, they can be used to produce a stronger yarn than copper threads, the material used in regular bulletproof vests.2. American and Japanese researchers say they are a step closer to predicting severe weather in and around the Indian Ocean. Researchers have analyzed weather data from the region over the past 40 years and they've discovered a strong connection between extreme weather and conditions in the ocean. A BBC science correspondent says the findings could make it easier to predict droughts or, indeed, periods of heavy rainfall.3. The world chess champion Garry Kasparov began a match against the rest of the world on the Internet. Kasparov made his first move with a meter-high pawn before an audience of chess fans at a park in New York. The move was immediately posted on a special website set up by the Microsoft corporation. Visitors to the site have 24 hours to vote on their counter move helped by a team of young chess experts who will suggest strategies.4. Few scientific advances of this or any millennium can rival insignificance the discovery of the structure of DNA, the basic molecule of life. Knowledge of the structure of DNA helps explains many things, including genetic mutation and , through it, evolution. Understanding its code has helped to unlock the mechanics of inherited disease, as well as beneficial biological traits such as intelligence and body strength. The discovery of the DNA molecule also paved the way for many of today’s cutting-edge sciences, including genetic engineering, a controversial branch of knowledge that raises new ethical and moral questions that are certain to be with us far into the next millennium.5. Some say it's hard to find good help these days, but a Japanese electronics firm thinks it's found the answer. It's a robot that talks and understands orders. The robot from NEC can record and send video mail through the Internet and switch on TVs and VCRs. And if it's becoming a bit warm for you, one simple command and the robot will switch on the air conditioner.B.2. lightning patronizingX rays EnthusiasticLaser BoredYeast Friendly / intimateFriction Loudly but neutralRecycling PatientlyTapescript:1 ....

So don't even think of trying to tell them you're a famous footballer or brain surgeon or television presenter.2. The jamming, earlier this month, of several popular Internet sites witha flood of crippling messages sent a wakeup call to those involved with electronic or e-commerce. One recent suggestion is to form an industry-wide group to share information about security issues. High-tech executives want to make a coordinated effort to ensure that the Internet becomes a safe place to conduct business.3. Now home to some 800 million pages--a figure that's doubling each year- searching the Internet can be like looking for a needle in a haystack. But Oslo-based Fast Search& Transfer (FAST) has developed a search engine (www. alltheweb, com) capable of scanning more than 200 million pages. FAST is working on a mega-search engine that searches "all the web, all the time."4. This week, the Intel corporation held its semi-annual Developer Forumin Palm Springs, California. The gathering draws more than 2,000 hardware and software developers from around the world. Intel executives opened the event with a demonstration of a high-speed chip, code-named "Williamette." The chip, designed to power personal computers, has a speed of one point five gigahertz, making it almost twice as fast as Intel's popular Pentium III chip which runs at 800 megahertz.5. An online VCR seems like a bright idea but it's been quickly rendered non-functional by the copyright lawyers. Not for the first time, the Hollywood studios objected to re-transmitting network television shows, in this case for users to watch via the web. Programs were being made available for visitors to save remotely or record for subsequent viewing via Windows Media Player.Part II New Ways to communicateA1When a friend is online1.6milion3,000you can only contact someone (on the same network as you. ) using the same programLaugh out loud.A2online / popular / take off / signing up / by / make upobvious / disadvantage / bright / voice conversations / swap / funnyWhen you meet someone for the first time，do you ask their ASL? Do you LOL if they come out with something funny, and say CU L8er when you finish the conversation? If you know what I’m talking about, then you are probably already a user of instant messaging, or IM.The idea behind IM is simple. A program on your computer tells you when a friend is online. You can then send a message to your friend, who can type a reply instantly. To do this, you need an IM program. Worldwide, AIM, the instant messaging service provided by AOL, is by far the most popular. It has 195 million users who send about 1.6 billion messages every day. ICQ, which is owned by AOL, has about 140 million messengers, and MSN and Windows IM make up about 75 million users. The advantage over e-mail is that with instant messaging you know you’re likely to get a reply. IM is already hugely popular in the USA, where people spend five times more time online than in Europe. However, IM is starting to take off in the UK, with over 3,000 people signing up to MSN Messenger alone every day.While the plus points of IM are obvious, there is one very important disadvantage: you can only contact someone on the same network asyou. If your friend is using AIM, and you are using MSN, you cannot talk to each other. This makes IM less useful than it should be. Imagine if you couldn’t send an e-mail form hotmail to yahoo. However, things look like they’ll change soon.In general, the future looks bright for IM. Lots of programs also allow you to have voice conversations, video conferencing ---- this means you can see the other person using a webcam ---- and also let you swap pictures, music and other files.So, perhaps we’ll all soon be asking someone’s age, sex and location (ASL), and laughing out loud (LOL) when they say something funny. See you later (CU L8er).B:1. FFTTFHow do you meet new people, make new friends, or find out about the latest bands? Here in the UK young people have traditionally done their socializing in bars, pubs and clubs.However there is a new generation growing up that finds it easier to manage their social lives on the net, using free websites like MySpace, Bebo or MSN Spaces.Welcome to the social networking website ---- a place where you can present yourself to the digital community and meet other like-mindedpeople.The most successful social networking website in the UK is . as of July 2006, MySpace is the world’s fourth most popular English-language website, attracting almost 3 million visitors per month. Myspace claims to have 95 million members with 500,000 new members joining the community each week.So how has it become to successful? Perhaps its secret is in its simplicity. Each new member can build their own page simply --- uploading photos, videos and MP3 files. Then they describe themselves, listing their likes, dislikes, favorite bands, relationship status, etc. it’s an easy way to hook up with people who share your interest.Briana Dougherty, a 25-year-old MySpace devotee, told us, “It’s a casual way to stay in contact without appearing weird. ” it seems that many people do not feel comfortable giving out their phone number or personal e-mail address to new acquaintances but are perfectly happy to trade MySpace profilesWhile socializing is the key to MySpace’s success, love of music is at the heart of the community. Indeed, most aspiring musicians in the UK upload their songs to the site, and with good reason: unsigned artists, Arctic Monkeys and Lilly Allen created such a buzz on the site that they were offered recording contracts and scored number one hits.Social network sites could be a great place to practice your English.Why not give it a try? You can tell us about your experience by filing in the new comments form at the top of the screen.Statements:Most young people in the UK make new friends at work.Yahoo and Google are social networking sites.MySpace is one of the top five English-language websites.New bands put their music on the web for people to listen to.Users of social networks usually pay for the service.Unit 8 ArchitecturePart I Warming upA.Tapescript:For hundreds of years, it has been an imperial capital of Europe. Its rulers raided the Western world to enrich the coffers of the empire. They spent their wealth on magnificent palaces and grand public buildings. They built an opera house that rivals any in Europe. They founded great museums and libraries. They constructed massive, ornate government buildings. And they raised opulent palaces for themselves. A tour of Vienna is a tour of these monuments to excess.Take Schonbrunn Palace, for instance. The Palace's Million Room, namedafter the cost of the decorations -- 1 million guilders, is a Rococo masterpiece. Inset in the paneling are 260 rare miniatures of Indo-Persian heritage. The frames are real gold leaf, and the paneling is precious wood.The Great Gallery, modeled after a room in Versailles near Paris, has 35-foot ceilings graced with giant frescoes（壁画）boasting of the power of the Austrian army. Massive crystal chandeliers reflect in the wall of mirrors, trimmed in gold leaf.The list of other sights to see in Vienna is long. St. Stephen's Cathedral dominates the skyline of Old Town, the medieval section of the city. Its main spire soars 450 feet into the sky, and the top can be reached by climbing 343 steps. The cathedral' was begun in the 12th century.In the catacombs（陵墓）beneath the cathedral are copperurns（骨灰坛）containing the intestines of deceased Habsburgs. Their bodies are in ornate caskets（棺材）in the Imperial Burial Vaults in the Kapuziner Church a few blocks away, and can be visited.The Old Town is a fascinating place to walk. Most of the narrow streets have been turned into pedestrian malls lined with shops, coffeehouses and restaurants. In one section, the original Roman ruins under the streets can be seen by going to an underground museum. The Natural History Museum and the Museum of Fine Arts occupy matching buildings on Maria Theresa Plaza, a small square across fromthe Hofburg. Hofburg is the Habsburg’s in-town palace. It is big, with 2,600 rooms, but not ornate. Hofburg is a jumble of buildings constructed at different times and in different styles, from Baroque, Gothic and Classical to Renaissance and Rococo. Its oldest parts date from the 13th century, but most were built from the 1700s on.B1.The Palais du Louvre:Location: heart of ParisBeginning year of construction: 1527Time when first used as a public art gallery: 1793The Louvre Pyramid:Designer: Ieoh Ming PeiUse: the main entrance to the Palais du LouvreHeight: 21mWidth: 33mMaterials: steel tubes, cables, sheet glassYear of completion: 1988Tapescript:The Palais du Louvre stands at the heart of Paris, and houses one of the world's greatest collections of works of art.

That may be an impossible question to answer. There are different meanings of the words “most popular.”●One way to measure the popularity of a sport is by the number of people who pay to watchit played by professional teams. Experts say the most popular American sport by that measure is baseball. Each professional baseball team plays 162 games every season.●Or the popularity of a sport can be measured by the number of people who watch games onthe television or listen on the radio. Then the answer might be American football.●And the popularity of a sport could be measured by the number of people who play thesport instead of just watch it.

Squeeze your fists tightly in front of your chest.Now push your elbows back –keep your head up! And relax…feet together, and put your hands on your hips. Now bend your knees and stretch your arms out in front of you. Hold that position – now up. Stretch your arms to the sides at shoulder height, palms up. Rotate your arms in small circles – that’s right – and now the other way. Now stand with your hands clasped behind your neck and your legs apart. Bend over to the left, slowly, but as far as you can.

I mean, I’ve heard other people say they’ve gone to football matches and there’s been absolutely no trouble in the terraces at all. And people have been… sat there, you know, quite happy, opposing teams next to each other.J: Oh but it obviously does happen a lot. I mean, you see it on the news.

By 2004, the Paralympic games in Athens had almost 4,000 athletes from 136 countries.Athletes may have physical or mental limitations; they may be blind or in wheelchairs. Yet sometimes they perform better than athletes without disabilities.Wheelchair tennis is a popular sport. So is basketball. In fact, there are more than 100 professional teams playing wheelchair basketball.Special wheelchairs for athletes are lightweight and designed for quick moves. For people who want to go really fast in their chairs, there is a power wheelchair racing association.In the state of Utah there is a place called the national ability center. It teaches all kinds of sports to people with all kinds of physical and mental disabilities. It even gives friends and family members a chance to try a sport as if they were disabled.A reporter from the Washington post wanted to know what it would be like for a blind person to use a climbing wall. So, protected by a safety line, the newspaper reporter closed his eyes and started to feel for places to put his hands and feet. Trainers on the ground urged him on; “take your time. You can do it.” Finally he reached the top.At the national ability center people can learn to ride horses and mountain bikes. They can try winter mountain sports, and learn scuba（水肺）diving and other water activities. The center also prepares athletes for the Paralympics.For disabled people interested in yoga, there are special stretching exercises. Matthew Sanford knows about these. He has been in a wheelchair ever since a car accident when he lost the ability to move his legs. He was thirteen years old at the time. That was almost thirty years ago.Matthew Sanford says he has had two lives: one before he was thirteen and the other after. Ha had to learn to live a new reality. For many years, he was told to build up the strength in his arms and forget about his legs.But he says yoga enabled him to reconnect with the thirteen-year-old boy who loved his body. He says the exercises and special breathing of yoga let him connect his body and mind again. Now Matthew Sanford teaches yoga at his studio in the state of Minnesota. He also travels to talk to people about living with a disability. He says feeling connected to our body is a powerful part of living-whether we have a disability or not.Today there are more and more choices of entertainment for people with disabilities.Theaters may offer wireless earphones to make the sound louder for people with limited hearing. Some provide a visual interpreter to describe a performance or a play fro a person who is blind or has limited sight.And some movie theaters offer a new device（设备）called Mopix, for Motion Picture Access. For a person unable to hear the movie, it shows the words the actors are saying. For a person unable to see the movie, it provides a spoken description of what is happening.Unit 7Part I Section AIt's a pleasant 73 degrees here. For those of you traveling tomorrow, here is a quick look at the weather for cities around the world. In Amsterdam it should be clear tomorrow with a high 82 and a low of 70. Athens is also expected to be clear with a high 80 and a low of 70. Bangkok will be cloudy with a high 90 and a low of 75. We also expect Beijing to be cloudy with a high 96 and a low of 64. In Bogota you'll need your raincoats with rain expected and a high of only 56. At night the temperature will go down to 48. It will also rain in Cairo but much warmer with a high 93 and a low of 73. Dublin will be cloudy, as it often is at this time of year, with a high 75 and a low of 55. Istanbul will be clear with a high 86 and a low of 70 while in Moscow the weather will be cloudy and on the cool side with temperatures only reaching a high 66 and going down to 48 at night. If you don't want hot weather, stay away from New Delhi, where the temperature is expected to reach a high 112 under cloudy skies and go down to a not very comfortable low of 80. For a beautiful day go to Warsaw, where the skies will be clear and the temperature a pleasant 79 degrees going down to 59 in the evening. And that's it for weather around the world.Section BA--Stranger One B--Stranger TwoConversation 1A: Excuse me. Can you tell me where the nearest bank is?B: The nearest bank...

School 10. ParkingRoad SignsThese are some of the signs that you see on the roads of the Great Britain.Number one is a sign with the number thirty on it. When drivers see this sign they must not go at more than thirty miles an hour. We see this sign when we get to parts of the country where thereare many houses and other buildings,for example, when we are getting near a town. Thirty miles an hour is the speed limit.Number two is the sign for the end of the speed limit. We are out of the town now and may go at more than thirty miles an hour.Number three a sign that we are near a cross-road, that is, a place where two roads cross. We must drive carefully.Number four a sign that there is a bend in the road. Again, we must drive slowly and carefully. Number five a sign that there is another road coming in from the right. This road joins our road; there is a road junction at this place.Number six a sign that there is a hill and number seven a sign that the road gets narrow. Drivers must go slowly and carefully.Number eight shows us a gate. There is a level crossing. This is a place where a railway crosses the road. The road and the railway are at the same level. There is no bridge. A level crossing is a dangerous place. Careful drivers stop or go very slowly. Is the gate across the road open or shut? Is there a train coming?Number nine has the word "school" on it. This is a sign that there is a school at the side of the street or road. Perhaps there are children going to school or leaving school. So drivers must look carefully and go slowly until they are past the school building.Number ten is a sign with the letter p on it. The letter p is for "Parking". A parking place is a place where drivers may leave their cars. If the driver of a car wants to leave his car and go to the shops, he looks for this sign. Then he knows that he may leave his car there.Part IISection A last month / oil / the environment / cars, buses, motorized bicycles / another kind of fuel / hybrids and vehicles that use other kinds of fuels than oilSection B1. electricity/ natural gas or propane2. walking, biking, using public transportation systems3. a. changes in the world climateb. air pollutionc. health problemsEnergy saving vehiclesˈvi:əkl were part of the Green Transportation Festival in Washington D.C., last month. The vehicles are designed to reduce America's dependence on oil and help the environment. The festival takes place in several American cities.There are exhibits of cars, buses, motorized机动化bicycles at the festivals. Most of them use little gas or use another kind of fuel such as biodiesel生物柴油, electricity, hydrogen化氢, natural gas or propane丙烷. People are also urged to consider simpler ways of getting around, such as walking, biking, using public transportation systems. Personal transportation vehicles, called scooters英小型摩托车,are also gaining interest. These methods all avoid or reduce the use of gasoline and diesel柴油机fuel, which are made from oil.Individuals, students and carmakers took part in the festival. They wanted to show people what their so-called "green" vehicles could do. Teams of students competed for prizes.The United States has less than five percent of the world's population. But it uses abouttwenty-five percent of the world's oil.More than half of the nation's oil is imported进口. Most of it goes to transportation.But festival organizers say progress in technology is making it possible for Americans to reduce their dependence on oil for transportation. That is because the kinds of energy-saving vehicles are increasing. Hybrid．．．．．．混合vehicles, for example, combine a gasoline engine and an electric motor. There are thousands on the road today. They can reduce gasoline use by as much as fifty percent. Festival organizers say that efforts to reduce oil imports in the United States would also have important environmental and public health benefits. The burning of oil as fuel is responsible for a large share of he gases blamed for changes in he world climate. When gasoline is burned in cars, it also pollutes the air. This leads to breathing problems, cancer and other health problems. Organizer say that strong public demand for hybrids and vehicles that use kinds of fuels could force carmakers to produce more such vehicles. That is the goal of the Green Transportation Festival.Part IIISection A this week/ road users / the number of road accidents / take basic measures / seat belts / focus more on road safety / safer roads / traffic-free play areaSection B Children playing in the street / Young and inexperienced car drivers / badly designed / badly maintained / road users / the rulesThe United Nations has opened the world's first Road Safety Week this week in a bid to raise safety awareness among road users and to reduce the number of car accidents. This week aimed especially at young people.&&& Latest figures at the World health organization showed that road accidents are now the biggest cause of deaths among young people aged between 10 and 24. Every year almost 400,000 young people die in road accidents although the type of road accidents varies. In Africa, which has the highest proportion 比率of deaths, those killed are frequently children playing in the street because they have nowhere to go. In Asia, where two-wheel's transport is common, young people are more often involved in motor-cycle accidents. While in Europe and the United States, most victims are young and inexperienced car drivers. &&& Doctor Attian Krug at the World Health Organization says a first step to saving these lives would be to recognize that road deaths are preventable."Road traffic crashes can, to certain extent, be predicted. We know that if road is badly designed, if a car is badly maintained, of if drivers, or road users in general, don't know the rules, there's going to be crashes. We know also that we can act on these different elements of the road safety system to prevent those crashes."UN Road Safety Week aims to encourage young people to take basic measures such as wearing seat belts and car helmets but it also wants governments to focus more on road safety too by designing safer roads and building traffic-free play area for children. &&&"It's a good investment投资," the UN says, "because road traffic accidents currently cost over 500 million dollars a year. They are not just a waste of young lives by an obstacle to development." Part IVSection A 1. increasing gridlock / urgent measures to promote mass transit systems 2.

This was the warning Tuesday from transport analysts分析家during a regional conference in Bangkok on sustainable可持续的transportation and air quality. &&& More than 100 transport specialists from 10 countries at the conference say the solution lies in providing better public transportation systems to lure 吸引car owners away from driving. Heather Allen, a manager with the International Association of Public Transport, says Asian cities need to stress transport systems over private car use."At the moment, I think anywhere in the world, the energy issue is very firmly on the table and the energy efficiency of public transport." She said. "Our experience and our research shows that on average you can go twice as far using public transport as you can with a private individual car."&&&Asia's love affair强烈爱好with the car appears very strong. In India, car sales in September were up almost 10 percent, while in China vehicle sales were up 33 percent from a year ago to 354,000 units. Both countries have booming economies and growing middle classes.But experts say such growth aggravated 加重the problems of increasingly crowded cities.Axel Friedrich from Germany's Federal Environmental Agency says such growth cannot be sustained维持as traffic snarls混乱increase in cities. Also, he says, more private cars aggravate pollution problems and increase economic costs because workers and cargo 货物get stuck on jammed roads.Transport analysts say that new systems such as underground railways are often too expensive and provide low returns to investors or governments.The most efficient systems and fastest to implement手段are bus systems. But Mr. Firedrich says governments often face local political and business interests when trying to put in place such efficient, low-cost transport systems.Unit 8 Trends in EconomicsPart IA.1.$25,000,000,0002.$161,000,0003.$37,000,000,000/ 28,000,000,000 dollars / $ 24,000,000,0004.30,000,0005.$1,000,000,0006. 5.5%/7.5%7.550/ 7%8.0.25% , 4.75%, 4.5%B.1. increasing their protest s against rising fuel prices2. a meeting of African nations3. the Czech Republic/ by early 2003/ a conference of EU members4.

Mr. Phelps is a professor of economics at Columbia University in New York City. The Royal Swedish Academy of Sciences honored Mr. Phelps for his work in macroeconomics. That is the study of large forces that affect economies at the national or international level.Mr. Phelps correctly identified the relationship between unemployment and inflation. Since the 1930s, policymakers in many nations dealt with unemployment in the same way. They would let inflation increase to create jobs.For example, they would make credit贷款easier to get. As a result, people would buy more goods. Business would hire workers to meet growing demand, forcing prices up. For many years, policymakers accepted that reducing unemployment required higher inflation.Mr. Phelps found that inflation did temporarily increase employment. But he discovered that, over the long term, inflation hurt job creation. His ideas were proved by economic conditions in America in the 1970s. That period was known for “stagflation停滞性通货膨涨having high unemployment and high inflation at the same time.”Edmund Phelps also found that if employers expect low inflation in the future, they are more likely to hire workers.Today, economic policy experts believe the best way to create job is to fight inflation.Mr. Phelps also studied national savings over long periods of time. Common sense suggests that a very high savings rate is best. But, Mr. Phelps showed that national savings rates can be too high. He argued that saving too much limited demand in the present, which could slow growth.The best savings rate is not so high that it limits demand in the present. And it is not so low that it limits growth and investment in the future. Still, he argued that governments should take action to raise national savings.Edmund Phelps did much of his research in macroeconomics during the late 1960s and early 1970s. His work continues to influence economists. And it has helped change policy at central banks, which now consider fighting inflation a main goal.Part III A.1. noisy place/ bell/ lighted messages/ computers/ talk on the telephone/ shout/ run around2. experts/ salespeople/ buy & sell shares of companies3. shares4. a list of stocks sold on the New York Stock Exchange5. prices/ go down6. prices/ go up7. a company that does not earn enough profit8. a sharp increase in the value of a stock/ something wonderful that happens unexpectedlyB.1. in 1837 in a newspaper in Illinois2. old story/ sold the skin of a bear/ before caught it3. a long connection/ bulls and bears/ in sports/ popular years ago/ England4. fish/ turn over on their backs/ die5.

This noisy place is a stock exchange. Here experts, salespeople called brokers, buy and sell shares of companies. The shares are known as stocks. People who own stock in a company own part of that company. People pay brokers to buy and sell stocks for them. If a company earns money, its stock increases in value. If the company does not earn money, the stock decreases in value. Brokers and investors carefully watch for any changes on the big board. That is the name given to a list of stocks sold on the New York Stock Exchanges. The first written use of the word with that meaning was in a newspaper in Illinois in 1837. It said, “The sales on the board were $ 1,700 in American gold.” Investors and brokers watch the big board to see if the stock market is a bull market or a bear market. In a bear market, prices go down. In a bull market, prices go up. Investors in a bear market promise to sell a stock in the future at a set price, but the investor does not own the stock yet. He or she waits to buy it when the price ducks. The meaning of a bear market is thought to come from an old story about a man who sold the skin of a bear before he caught the bear.
