The theory and function of acupuncture.A21. A week ago / Parkinson’s disease.2. A natural defense mechanism3. The death of brain cells4. Meeting patients’ psychological needs produces physical health benefits.5. Side effects / cut back on medication.1. The world’s leading transplant surgeon, Dr Christo pher Bernard, has carried out one of the most difficult brain tissue transplants yet attempted. 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 suffering from 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.2. 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.3. 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.4. 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 inclinically 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.5. 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 by inserting 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/Part IV1. NHS’(英国国民健康保险制度) greater focus on prevention1. a gimmick2. a: increased screening2. proper timetablee.g. heart disease, stroke, cancer 3. treatmentb: the most vulnerable4. private healthcarec: more widely available听力原文：It seems that politicians around the world are thinking about the health of their countries. While in China, Chen Zhu has announced his plans for a universal health service and reform across health services, Gordon Brown, the UK Prime Minister, ahs also announced he is planning to make some changes in our heath service.The crux of Mr. Brown’s propos als are related to giving the NHS （National Health Service）a greater focus on prevention, rather than just curing patients.He is planning to introduce increased screening for common diseases such as heart disease, strokes, and cancer, for example breast cancer. In Britain there are 200,000 deaths a year from heart attacks and strokes, many of which might have been avoided if the condition had been known about.Initially, the diagnostic tests will be available fro those who are most vulnerable, or most likely to have the disease, but later on the Prime Minister claims that they will be more widely available. One example is a plan to offer all men over 65 an ultrasound test to check for problems with the main artery, a condition which kills 3,000 men a year.The opposition have criticized Mr Brown’s proposals, saying that they are just a gimmick, and claiming that there is no proper timetable for thechanges. They also say that Mr. Brown is reducing the money available for the treatment of certain conditions while putting more money towards testing for them.The NHS was founded in 1948, and is paid for by taxation. The idea is that the rich pa more towards the health service than the poor. However in recent years there has been a great increase in the use of private healthcare.Many people who can afford it choose to pay for medical care, often because it can be quicker, although the doctors and hospitals are often the same!! NHS waiting lists for operations can be very long, so people can jump the queue by paying for their operation.英语专业学生经典的听力材料Unit 8 ArchitecturePart I Warming upB1.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. The original palace dates from 1527, and it was extended and added to over the next four centuries. It was first used as a public art gallery in 1793. In 1981, theChinese-American architect Ieoh Ming Pei was commissioned to redevelop the public part of the Louvre and create more space for reception areas and services. He designed the famous Glass Pyramid, which serves as the main entrance to the building, leading underground to the museum and art gallery. The Pyramid is 21 meters high and 33 meters wide, and uses a combination of steel tubes, cables and sheet glass. It was completed in 1988, and quickly became a major tourist attraction in its own right.B21. She likes the Louvre Pyramid because of the transparency, and it has a light effect.2. She likes the Louvre Pyramid for its contrast of shapes. It emphasizesthe beauty of the Louvre.3. She thinks the right thing is to put something so contradictory to the Louvre. They stand in dialogue with each other and they don't try to complement each other.4. She thinks it would have been the biggest mistake to try to build something similar to the Louvre.Tapescript:I like the Louvre Pyramid because of its transparency, because you can just look through it, and it has a very light effect. It is not heavy and it is made of glass, and so it looks like a light object. And I like it for its contrast of shapes, because it is such a contrast to the Louvre building that in fact it doesn't interfere with the beauty of the Louvre, but it even, it emphasizes the beauty of the Louvre. And in the evening when this pyramid is lighted, it's just a source of light to put the Louvre into a new light. And this has for me also a symbolic meaning. And it is such an unexpected shape in this urban context, just to use a traditional shape of a pyramid built in new materials with new technologies, high-tech, and so on, that it is a completely surprising effect. So that people get shocked by it or they like it, but there is nobody who would be uninvolved or who could just pass and not notice this building. So it's something you have to look at. And I think this is also very important in building, and creating something in the cities, and exactly for example close to these historicalbuildings which are such a... they are so sensitive topics that nobody dares to touch them. I think the right thing is really to put something so contradictory to it that they stand in dialogue with each other and they don't even try to complement each other. Because it would have been the biggest mistake to try to build something similar to the Louvre, to put a building which would copy the Louvre, because it would just mean that we don't live in continuity, the architecture doesn't continue its history, but it would mean that architecture stands still on the level of the 17th century, and that would be a lie.Part II eco-conscious constructionAThe world’s first eco-city /off the coastAgricultural land /half a million /$1.3 billion /a sustainability consultantSustainable developmentA more ecologically friendly model /minimize impact on nature /solar and wind power /power and fertilizers /electric cars英语专业学生经典的听力材料Unit 11 TourismPart IA1. resort3. Golden Mile4. stag and hen partiesThe south coast 1. its pier with theaters / restaurants 2.shoppingSouthwest 1. scenery2.warmer climate2. British surfing1. Blackpool2. South CornwellTranscript:Most visitors to the UK come here expecting the rain and miserable weather for which the country is famous. However, when summer finally does arrive, the British people like nothing more than packing their trunks and swimming costumes and heading for the coast. The UK is, after all, an island, and with 12,400 km of coastline to explore. Any visitor to the UK will be spoilt for choice. Here are some of the more famous resorts that you could expect to visit on a rip to BritainBlackpool, in the northwest of England, is the most visited resort in the UK. Each year around 6.5 to 7 million people come to enjoy the mile of sandy beaches, the 158 m Blackpool Tower and the 11 km-long Golden Mile, where there are entertainments, pubs, ice rinks and even a zoo. A firm family favorite, it has also become a popular destination for stag and hen parties.At the other end of the country on the south coast you can find Brighton. Until 1786, Brighton was a sleepy village. Then the future King George IV decided to build a residence there, and over the years Brighton grew into the large, cosmopolitan center it is now.A part from the beaches, Brighton is famous for its pier. On the pier there are theaters, entertainments and restaurants. Brighton is also fantastic for shopping.If you fancy traveling a little further, why not go to Cornwell inn the far southwest the UK? South Cornwell offers miles of sandy beaches andbeautiful scenery. The climate here is warmer than the rest of Britain and you can even find plan trees.For a bit more excitement, go to North Cornwell. The scenery here is more dramatic, and the beaches are famous for their powerful waves. As a result, North Cornwell has become the home f British surfing.One word of warning though, if you are using the roads in the UK on bank holidays or during school holidays, you can expect long traffic jams on the motorways. It might be better to take the train.Part IIAExcessive visitors (averaged 50,000 during golden weeks)Cultural relics in the museumAn electronic ticket checking system1). Real time record of the number of visitors inside the museum2). Maximum reception capacityThe flow of touristsTranscript:Troubled by excessive visitors, the Palace Museum or Forbidden Cityin Beijing will adopt an electronic ticket checking system and make the control of the flow of tourists. The new system will keep a real time record of the number of visitors inside the museum, and inform the ticket office to hold ticket sales onc e the number exceeds the musuem’s maximum reception capacity. The Palace Museum, on of the most comprehensive Chinese museums, in terms of history and art, was established on the foundation of the palace that was the ritual center during two dynasties, the Ming and the Qing, and their collection of treasures. It has topped the must-see list of almost every visitor to the capital city. In recent years, the number of daily visitors to the Palace Museum averaged 50,000 during golden weeks, the week-long national holidays observed three times a year in China. Superfluous tourists have caused damage to cultural relics in the museum.。

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'sstruggling 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 measuresput 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 reduceits 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 issued temporary bans on the import of all animal produce from EU countries.BForeign exchange rates:1 dollar = 1.733 German marks= 126.9 Japanese yen1 pound =1.624 dollarsShare IndexDow Jones up 6,783 (+45) London’s 100 up 4,390 (+20)Nikkie closed2.

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 P arkinson’s disease. A portion of the patient’s adrenal gland was implanted into a part of the patient’s brain, an operation whichhaspreviously 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 themajor 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 thoughtsabout 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 associatedwith 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 by insertingneedles 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 engineering artificial 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 sayswhile 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 andthey'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 ontheir 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 basicmolecule 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 intelligenceand body strength. The discovery of the DNA molecule also paved the wayfor many of today’scutting-edge sciences, including genetic engineering, acontroversial 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 ....

Genes are located on chromosomes that in turn reside in every cell in arrangements similar to the alternately colored rungs on a ladder. The sequence of genetic rungs produces the chemical instructions the cells need in order to build and run the human body.

And British papers report the latest trend when you meet someone in a bar is to get their number, go home, and google them. Yes that gorgeous girl or guy you met the other night is probably patrolling a search engine right now to check you out. 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 Internetsites with a 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 asIntel'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. ) usingthe same programLaugh out loud.A2online / popular / take off / signing up / by / make up obvious / disadvantage / bright / voice conversations / swap / funny When 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 1.6billion 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 as you. 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 andlocation(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-minded people.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 millionvisitors per month. Myspace claims to have 95 million members with500,000 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 aneasy way to hook up with people who share your interest.Briana Dougherty, a 25-year-old MySpace devotee, told us, “It’s a casual wa y to stay in contact without appearing weird. ” it seems thatmany 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 atthe heart of the community. Indeed, most aspiring musicians in the UK upload their songs to the site, and with good reason: unsignedartists, 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 byfiling 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 bandsput 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 publicbuildings. 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 powerof the Austrian army. Massive crystal chandeliers reflect in thewall 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 copper urns(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.

To succeed in life, a man must learn to develop such qualities in himself asindustry, persistence, confidence, and strong willpower. Here I would like to dwell alittle on the first two.Undoubtedly, hard work is the key to success. Take Peter G. Beidler for example. Having chosen teaching as his career, Professor Beidler made a great effort to meet the challenges of the profession. Day after day he stayed up late preparing his lectures,even when his eyes became swollen for lack of sleep. His subsequent success as ateacher was borne out by the fact that he was named The Professor of the Year in 1983. Obviously his success has had a great deal to do with hard work.Persistence is another important factor leading to the realization of one's goal in life. Once we have set a goal for ourselves, we must not depart from our course untilwe reach it. The mother in Unit 5 is a case in point. She refused to give up in the faceof all the challenges in life. Instead, she persisted in improving herself. In the end, she became a reporter with a local newspaper. Clearly persistence helped to make herdream come true.。

UNIT 8Section One Tactics for ListeningPart 1 Spot DictationOnce upon a time，all- or almost all—businesses were (1) greedy and rapacious，sparing a thought for their （2）workers or the environment only in order to （3）work out how to exploit them。

They discovered the idea that companies should not exist only to make a profit but to (7) serve society。

The amount of water taken from rivers for commercial use is to be cut and farmers will be compensated.2. The disappearance and deformity of amphibians such as frogs and sala manders from rain forests and mountain lakes worldwide has attracted wi de-spread scientific attention over the last decade. Now a new study says reptile species including turtles, snakes, and alligators are in even greater tro uble. Twice as many reptiles as amphibians, or some 100 species, are curr ently listed as endangered by the World Conservation Union. The study s ays habitat loss and degradation, pollution, disease, climate change, and o ver-collection for food, pets and drugs are the major threat to reptiles.3. Four regional governors from Columbia, on a visit to Washington, have sharply criticized an American-backed aerial offensive to eradicate thousands of hectares of illegal coke and poppy plantations.

He says it is a mistake “to confuse the vibrancy of the virt ual world with the increasingly troubled state of the real world.”“We give the earth an annual physical, and this book is the result of that a nnual physical. We check its vital signs. And almost all those vital signs, whether it‟s the number of species, whether it‟s the stability of climate, w hether it‟s the number of species, whether it‟s the stability of climate, wh ether it‟s the health of coral reefs, all those trends show deterioration.” Lester Brown says other warning signs are rising temperatures, falling wa ter tables, melting glaciers, shrinking forests and collapsing fisheries. He says the major environmental challenges in the 21st century will be to sta bilize both climate and world population growth.Worldwatch Institute President Lester Brown also points out initiatives b y multinational corporations to seek energy alternatives.

One hundred and fifty experts aro und the world will discuss the water situation at a conference beginning Monday in Geneva.A top official from the World Meteorological Organization Arthur Askew says that by the year 2025, almost 1 billion people could be living in area s suffering from a scarcity of water. He says the number could double by the middle of the next century. Mr Askew says one area with serious wate r problems is the Middle East. But he says officials in the area are already working on ways to deal with the situation.Experts say water shortage problems also could develop in parts of Africa and western Asia as well as northeastern China, western and southern In dia, large parts of Pakistan and Mexico, and parts of the Pacific coast of t he United States and South America. Mr Askew says there‟s a moral obli gation to treat water as a precious resource and a need to realize that large amounts of water are used often wastefully in food production and manuf acturing.“All commodities have used water in their production and you must be a ware therefore that if you‟re importing food from one country to another you are in fact importing part of the water resources of that country.” Mr Askew also says water shortages lead to a conflict between rural and urba n demands.“In many regions of the world, the water crisis is not coming because of human consumption directly for potable water, for drinking, or for sanitar y purposes, it‟s coming for agriculture. And in general about 80 percent o f the water, which is consumed, i. e., is extracted from the rivers or from underground resources and is not returned, is for agriculture. And there‟s considerable pressure now on the agricultural sectors to see if they cannot use that water ore efficiently.Mr Askew says it‟s estimated that a person needs about 5 liters of water a day to survive, and a person needs about 5 liters of water a day to survive, and a person lives comfortably with about 50 liters a day. But he says peo ple in many countries are using 500 liters of water each day. He says way s must be found to reduce such overuse before it‟s too late.Part III City recyclingA a. 2 b. 4 c. 3 d. 1B1.130,000 / 80%2. Plastic / glass / tin cans / newspapers3.

Because of that, more communities are encouraging their residents to rec ycle, to set aside certain materials that won‟t go to the landfill. One area t hat‟s met the recycling challenge head-on, is the southeast City of Charlotte, North Carolina. In just a few years, its recycling program has become one of the country‟s most successful. Catherine Smith lives in one of the 130,000 eligible recycling househol ds in Charlotte, North Carolina. Nearly 80 percent of the households parti cipate in the program. Each week, Smith goes to her front porch and fills her red plastic bin with recyclables. “You‟ve got any plastic containers m arked one or two. You‟ve got any glass. They also recycle tin cans and ne wspapers. So all of that can go in the curbside pick-up bin.”“Well, this is the easy part. Then someone, ah, driving a Charlotte Mec klenburg …Recycle Now‟ truck comes and, usually, at some point—tomorrow or Friday—and they pick it up at curbside. And that‟s it.”From there, Smith‟s cans, bottles, and newspapers are taken to oneof the community‟s recycling centers. The City of Charlotte actually cont racts with a private company to process the recyclables.This plant is operated by a company called FCR. The recycling trucks pull into FCR each weekday morning to drop off the used material. Inside, the processing center at FCR is bustling with activity. One of the first thin gs you notice in the 26,000-square-foot facility is a huge mound of materials called the “commingle area.” B asically, it‟s a big pile of assorted trash. There are forklifts transporting g arbage, and people sorting through it. Paula Hoffman is education coordin ator at FCR. She conducts tours of the plant for more than one thousand p eople a month.“The aluminum cans, the number one and number two plastic container s, the spiral cans, the glass bottles and jars are all mixed together into a hu ge pile. And…we are receiving about 100 tons a day, which is 200,000 po unds, so you can imagine how many bottles and cans are in that pile.”“Can we walk around a little bit?”“As you can see, the bottles and cans are riding up the conveyor belt, a nd they‟ll end up on a sorting station, where there are twelve workers that will hand-sort the bottles and cans and other containers. As you can see, from the sorting station, they drop their material down a chute into a large container below. The sorting station is on a raised platform.” Across from the sor ters and the commingle area is a mound ofnewspaper. Of the material brought to FCR, three quarters of it is newspri nt. It rides a separate conveyor belt, is checked, and is compacted into bal es, 11 to 12 hundred pounds each. Back in the quiet of FCR‟s auditorium, Paula Hoffman describes what happens to the sorted and processed recyc lables the company receives from Catherine Smith and the thousands of o ther area residents. Hoffman says they‟re sold to other companies that the n make them into different products.“Your food and beverage glass containers are always made into new fo od and beverage glass containers. Your aluminum beverage cans are, the biggest percentage of the time, made into new aluminum beverage cans. Twenty five percent of all beverage, Coca-Cola, Pepsi bottles are now made into new Pepsi or Coke bottles. Howeve r, a certain percentage is also made into other products such as the fuzz o n a tennis ball, carpeting…your number two plastic…a lot of it‟s made in to plastic wood.”Charlotte, the surrounding county, and FCR are glad to add new recycl ables to their program as long as there‟s a need for the recycled material.From its high participation rate to the quality end product, Charlotte‟s rec ycling program is considered one of the top five in the nation.But ultimately, the success of the Charlotte area recycling program can be traced to the curbsides of the many individual citizens who, like Catherine Smith, are active participants in program.Unit 3 World News: Economic DevelopmentsPart I Warming upA1.

Central Bank governors from more than a dozen countries have been meeting 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.

How are the 100 companies distributed?46 in the United States, 54 in Europe and Japan.4. Why were none of the Internet-related firms included in the list? Because most of the Internet-related firms have little or no profits so far. Tapescripts:For the second year in a row, the General Electric Corporation is ranked number one in an annual survey of the 100 most powerful corporations in the world.The survey, compiled and published by Forbes business magazine, shows General Electric of the United States ranked number one, followed in second and third place by the U.S. banking and financial services giantsCitigroup and Bank of America. In fourth and fifth place are the British-based HSBC Banking Company and Daimler-Chrysler, the German-American auto-company. The companies are ranked with a composite formula, which includes total sales, profits, assets and market capitalization, or the total value of its (their) stock. What the magazine calls its "Super 100 Global" list are 46 companies based in the United States and 54 in Europe and Japan.Mike Ozanian, the Forbes editor who compiled the list, says there is a growing trend of international mergers and acquisitions, citing companies such as Daimler-Chrysler and BP-Amoco, the Anglo-American Oil Company. Mr. Ozanian says that despite the huge capitalizations of many Internet-related firms, none were included because most have little, if any, profits -- at least not yet.BSummary:This news report gives us a general picture of the U.S. stock market. It also presents some analysts' views on the market.Statements:1. The Dow Jones Industrial Average went up less than one percent, to 10,546.2. An analyst said that sales growth at Intel could be stronger than expected.3. Retail stocks gained on stronger-than-expected sales because of the Thanksgiving holiday shopping season.4. Sales of existing homes fell a steep 3.9% in October, their second monthly decline.5. According to investment strategist Alan Skrainka, this is a very good entry point for a long-term investor to get into the market. Tapescript:U.S. stock prices were mixed on Monday, with the "blue-chips" in a rally mode. But volume was only moderate after a holiday-shortened week last week, showing lingering uncertainty among investors.The Dow Jones Industrial Average went up 75 points, less than one percent, to 10,546. The S & P 500 Index gained 7 points. But the NASDAQ Composite backed off an early rally, taking a loss of almost one percent on weakness in selected technology stocks.The Dow Industrials actually got a boost from their technology components. Shares of Intel traded higher after an analyst said sales growth at the leading computer chip-maker could be stronger than expected. Microsoft stock also edged higher.Retail stocks gained on stronger-than-expected sales over the Thanksgiving weekend, as the holiday shopping season got underway. However, analysts caution the retail picture is still clouded because many stores offered bargains to attract shoppers. Experts worry that higher oilprices and interest rates will make this a less than merry Christmas season for U.S. merchants.The latest on the U.S. economy points to slower growth. Sales of existing homes fell a steep 3.9 percent in October, their second monthly decline. Many analysts think uncertainty over the economy makes it increasingly likely that the major stock averages will close lower for the year.

The focus of the party was the planting of a single tree, the first of 20 million to be planted in 40 Californian cities over the next decade. The tree planting campaign is an attempt to deflate what’s been called the Greenhouse Effect. Scientists believe that the earth is getting warmer because of an accumulation of carbon dioxide in the air. Trees take carbon dioxide out of the air.Martin Rosen is the director of the Trust for Public Land, the organizationthat is coordination the stat-wide tree plating effort. “Time is not neutral. We are so rapidly depleting the atmosphere, we are so rapidly changing the climate, that unless we start now the situation may well become irreversible.”Some movie stars were on hand for the tree planting ceremony. Actor Peter Cyote served as the master of ceremonies. “Unless the environmental movement comes into everybody’s life, in real simple activities, it’s not going to work. Planting a tree is real simple. So I wanted to participate in something that was really accessible to the citizen, just to everyday people, to children. So that as citizens we can do a lot.”After Peter Cyote introduced a few speakers and a couple of songs were sung, the ceremony moved over to a corner of the park where a group of youngsters planted a Copper Beech tree.Isobel Wade is the state coordinator for Campaign California Re-Leaf. Wade says the tree plantings are important because they will help clean up the carbon dioxide in the atmosphere, improve the environment and make neighborhoods more attractive, but Isobel Wade cautions it isn’t enough. “It’s one step in a combination of things. The other kinds of things that we can all be doing are being much more conscious about how we use energy in our home, whether we’re buying—ah—fuel efficient cars and products, whether we’re using Styrofoam when we don’t have to be, --ah—whether we’re turning off light bulbs when we—ah—leave the room—um—and just a variety of personal actions like recycling that we need to start thinking about and doing more.”Isobel Wade also says she’d love to see everyone in California’s urban arrears take the time to plant one tree and take care of the ones that are already growing.Key B1.planting single tree2.deflate Greenhouse Effect/ take CO23.real simple activities/ accessible to people/ citizens/ do a lot4.clean up CO2/ improve environment/ neighborhoods attractive5. a variety of personal actionsPart IIIWhen you go to the supermarket, can you resist using plastic bags For lot of us, probably won’t. What you eat out Can you guarantee not to use any plastic tableware And how about if someone asks you; can you recommend a replacement for plastic products Don’t say paper! Here is a new solution; biodegradable plastic!As everyone knows, plastic is a big environmental headache although it brings us much convenience. Like plastic bags, plastic food containers, and plastic tableware. But it is perhaps the most harmful of all our garbage because it does not easily break down in nature.A researcher form the Chinese Academy of Sciences, Ji Junhui says he and his colleagues have found a better solution.“When the PBS in the biodegradable plastic comes in contact with microorganismsor enzymes, the plastic structure will degrade into smaller pieces, and finally it turns into water and carbon dioxide. This is how the break-down process works.”PBS is a chemical component that is the key to this new biodegradable plastic. It can help the plastic degrade into non-polluting elements, so the broken-down plastic fragments can be absorbed by soil and water.PBS is not an entirely new product, however, this China-made biodegradable plastic is safer and more heat-resistant. According to Ji Jun-hui, testing has shown that 90% of this new biodegradable plastic can be degraded within 90 days. And it even takes a shorter period of time if it is buried in a dump rather than exposed to the air.Usually, biodegradable plastic food containers made in other countries will melt when the temperature reaches 60 degree Celsius, while the Chinese product can retain its shape in up to 100 degrees.However, Ji Junhui says his-tech products often come at a higher price.“PBS product is a bit more expensive than ordinary plastic. Taking a plastic bowl as an example, the PBS bowl can be 20% more expensive than the current plastic bowl we use.”Some hotels and restaurants in Shanghai have already started using the new PBS biodegradable plastic food containers, and the product will be popularized in Beijing as well as in other big cities.It will play a role in the 2008 Olympic Games. Besides in the production of plastic food containers and tableware for the Games, PBS biodegradable plastic will also be used to make road signs, team cheering equipment like horns and mini flags, as well as trash bags, umbrellas and eyeglass frames.Probably in the near future, we will really be able to say “farewell” to plastic pollution.Key:OutlineI. headachenot easily bread downII.

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 dollar is trading at one German mark seventy-three point three and at 126.9 Japanese yen. The pound buys one dollar sixty-two point four. In New York, the Dow Share Index closed 45 higher at 6,783. EarlierLondon's 100 Share Index ended 20 higher at 4,390. In Tokyo, the Nikkei Share Index is closed for a holiday.2. The Dow Jones Industrial Average closed up 96 points at 10,116. The Standard and Poor's 500 Index gained 6 points to close at 1,254. But the NASDAQ Index lost 1.5% as high technology and Internet stocks were battered.3. Right now the Dow is down another 66 points at 8,094; the NASDAQ Composite down 3 points at 1,662. Turning to Europe's major markets: London stocks were hit by a wave of profit taking after five straight record closes; the FT 100 Index down 36 points; Paris seeing losses as well, the CAC quarante down 33 points or 1%; and Frankfurt's DAX also fell 1% after briefly moving into record territory.4. The Hang Seng Index closed down 89 points at 3,521. The turnover was 7.71 billion dollars. Now look at the ten most active stocks. Cable and Wireless HKT up 45 cents, HSBC holdings down 50 cents, Hutchison down 50 cents, Shanglongkai Property up $2.25, and China Telecom down $1.50, Chang Kong up 25 cents, Pacific Century Cyberworlds down 10 cents, CCT Telecom down 27.5 cents, New World Cyberspace down 7.5 cents, and Hanong Holdings down 25 cents. The Hang Seng Index future for November and December were all down. Hong Kong gold closed at 2,670 Hong Kong dollars, and London gold is trading at 289 U.S. dollars.5. Consumer electronics maker Philips Electronics reported a lower than expected profit for last year. The company made about $2.4 billion, more than $300 million below estimates.

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.

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 ....

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.

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.

The original palace dates from 1527, and it was extended and added to over the next four centuries. It was first used as a public art gallery in 1793. In 1981, the Chinese-American architect Ieoh Ming Pei was commissioned to redevelop the public part of the Louvre and create more space for reception areas and services. He designed the famous Glass Pyramid, which serves as the main entrance to the building, leading underground to the museum and art gallery. The Pyramid is 21 meters high and 33 meters wide, and uses a combination of steel tubes, cables and sheet glass. It wascompleted in 1988,and quickly became a major tourist attraction in its own right.B21. She likes the Louvre Pyramid because of the transparency, and it has a light effect.2. She likes the Louvre Pyramid for its contrast of shapes. It emphasizes the beauty of the Louvre.3. She thinks the right thing is to put something so contradictory to the Louvre. They stand in dialogue with each other and they don't try to complement each other.4. She thinks it would have been the biggest mistake to try to build something similar to the Louvre.Tapescript:I like the Louvre Pyramid because of its transparency, because you canjust look through it, and it has a very light effect. It is not heavy and it is made of glass, and so it looks like a light object. And I like it for its contrast of shapes, because it is such a contrast to the Louvre building that in fact it doesn't interfere with the beauty of the Louvre, but it even, it emphasizes the beauty of the Louvre. And in the evening when this pyramid is lighted, it's just a source of light to put the Louvre into a new light. And this has for me also a symbolic meaning. And it is such an unexpected shape in this urban context, just to use a traditional shape of a pyramid built in new materials with new technologies, high-tech, and so on, that it is a completely surprising effect. So that people get shocked by it or they like it, but there is nobody who would be uninvolved or who could just pass and not notice this building. So it's something you have to look at. And I think this is also very important in building, and creating something in the cities, and exactly for example close to these historical buildings which are such a... they are so sensitive topics that nobody dares to touch them. I think the right thing is really to put something so contradictory to it that they stand in dialogue with each other and they don't even try to complement each other. Because it would have been the biggest mistake to try to build something similar to the Louvre, to put a building which would copy the Louvre, because it would just mean that we don't live in continuity, the architecture doesn't continue its history, but it would mean that architecture stands still on the level of the 17thcentury, and that would be a lie.Ecology 生态学ecological system 生态系统Consultant 顾问Model 模式Minimize 减小，减少Part II eco-conscious constructionAThe world’s first eco-city /off the coastAgricultural land /half a million /$1.3 billion /a sustainability consultantSustainable developmentA more ecologically friendly model /minimize impact on nature /solar and wind power /power and fertilizers /electric carsB1.1. a dream-house which is sustainable by the environment ----- an environmentally-sustainable dream-house2. windows that face south -- south-facing windows3. a kitchen that is well lit -- a well-lit kitchen4. paint that is based on milk or uses milk as a base ---- milk-based paint5. solutions which are beneficial to the environment -- environmentally-beneficial solutionsTapescript.1.

The approach is being spearheaded by a quiet revolution in the eco-conscious construction business. Colorado Public Radio's Peter Jones recently visited a building site near Boulder andbrings us this report.J: Architect Jim Logan is building his environmentally sustainable dream-house at the site of a former commune a few miles north of Boulder. Logan has incorporated nearly every aspect of a modern eco-conscious design. As you drive onto the small farm property, you're immediately struck by a series of large south-facing windows. Walk through the well-lit kitchen, and you'll see that even the north side of the building has a passive solar component.L: Every room in this house has a window that faces south, regardless of where it's located, so all the rooms in the house have both day-lighting, which means that there's ample light coming in high into the room so that we don't need to use electric lights during the day, and also have south-facing glass that provides solar heat.J: As a result, Logan's house will have neither a furnace nor air-conditioning. For hot water, he'll tee an active solar heater. But efficient use of the sun is only one of the building's many eco-conscious features.L: The outside walls -- if you include a foot of adobe, a foot of insulation, and another foot of adobe- are three feet thick.J: The so-called super-insulation is required to store the solar heat, but Logan is also using thermal mass, or dirt, to keep the house both warm in the winter and cool in the summer.J: In all facets of construction, Logan is emphasizing both biodegradable building products and nontoxic materials. He's using milk-based paint, for example, and relatively little of that.L: This room and the inside of this room- virtually all the finishes did not need to be painted. The ceiling is made out of galvanized metal and the walls are plaster. Painting is a fairly un-environmental act in that it is something that involves chemistry, it involves doing it over and over many times in the lifetime of the building.J: And don't look for any carpeting in Logan's house.L: Well even if carpet is made from recycled material, it still can't be recycled the second time currently, so carpet virtually always gets thrown away. Also, most carpet gives off volatile organic compounds.J: Initially, Logan will get all his water from a well. The house won't be connected to a city water system. But he says the roof has gutters and will eventually collect rainwater for general use. Logan is paying $75 a square foot to build his house, and estimates environmental features added 10 - 15% to the up-front costs. But he says he'll save money in the long run. L: In many cases, many environmentally-beneficial solutions pay for themselves in as little as 6 or 7 or 8 months. A low-flow showerhead in most situations will pay for itself in a month.Part III Tomorrow's houseA.1. What is home automation? In your opinion, what are some of the things that could be examples of home automation?2. What are some of the main interests in creating automated houses?3. Can home automation offer benefits and lifestyle improvements for elderly and disabled people? Imagine how.B.Safety:Security systems that detect fires, gas and water leaks, intruders, unwelcome guests, etc.Security systems that limit home access to specific times of the day and tell you which doors and windows are openEnergy-efficiency:Lights that turn themselves off when you leave a roomSensors that help open skylights, turn on ceiling fans and close the draperies when the house reaches a certain temperature ConvenienceAppliances that tell you when something is wrong with them Security system, spa, lights, CD player, garage door, thermostat, stereo, etc. that can be controlled while in the house or remotely from a touch-tone phone or computer and modemLifestyle improvements for elderly and disabled people: voicecommand, infrared remote control, etc.Tapescript:Current advances in home automation offer homeowners convenience, security, energy savings and a lot of gee-whiz technology.With a fully automated home, you'd be able to pick up your phone, call your house and instruct it to disarm the security system, start the spa, turn up the lights and coax classical music from the compact disc player. While you were at it, you could also open the garage door or set the thermostat to a pleasant 70 degrees.Sound intriguing? How about lights that turn themselves off when you leave a room? A stereo that quiets itself when the phone rings? Or appliances that tell you when something is wrong with them?Although most home automation systems now on the market are expensive and available only in new homes, within the next two years you can expect an explosion of products that transform homes into architectural geniuses.By all accounts, the time is right for houses to become "smart." During the last decade, consumers have readily accepted such technological wonders as microwave ovens, fax machines and cellular phones. Our cars use microprocessors, automated tellers abound, and virtually everyone has access to a personal computer. The interest in home automation, however, is not born out of a desire to create a space-age home. It stemsfrom a genuine interest in ways to make houses safe, energy-efficient and more comfortable.Take security, for example. If there is a fire, an automated house will detect it, turn off the gas, close the dampers in the ventilation system, turn on the lights, unlock the doors, set off an alarm and call the fire department. More advanced systems might even tell you where the fire is and through which room you should escape.In the case of an intruder, a triggered motion detector can turn on floodlights in the yard and instruct your stereo to queue up the sound of a barking dog.Or say you want to avoid unwelcome guests. By mounting a video camera at the front door, you can view visitors on a TV screen. Automated security systems can also detect gas and water leaks, limit home access to specific times of the day and tell you which doors and windows are open when you activate the system.With Home Manager, one of several automation systems on the market, you can warm up the master bedroom, kitchen and bathroom in the morning before the alarm goes off. Or you can program it to keep the nursery at a constant temperature. In midsummer, you can even instruct sensors in the house to open skylights, turn on ceiling fans and close the draperies when the house reaches a certain temperature.All of these functions can be controlled while in the house or remotelyfrom a touch-tone phone or computer and modem.In addition, home automation offers tremendous lifestyle improvements for elderly and disabled people. For those who cannot push a button or flip a switch, a voice command can be used to activate security cameras, turn up the stereo volume or drop the room temperature a few degrees. The click of an infra: red remote control could turn on the oven, close the blinds or open the door.So what is home automation, exactly? In short, it's actually a combination of several things including microprocessors, enhanced power line transmission, computer chips, telephone and cable wiring, infrared sensors and radio frequency waves.Fortunately, the manufacturers that are developing these automated products understand that consumers don't care how something works as much as they care that it does work and is easy to operate.。

The focus of the party was the planting of a single tree, the first of 20 million to be planted in 40 Californian cities over the next decade. The tree planting campaign is an attempt to deflate what’s been called the Greenhouse Effect. Scientists believe that the earth is getting warmer because of an accumulation of carbon dioxide in the air. Trees take carbon dioxide out of the air.Martin Rosen is the director of the Trust for Public Land, the organization that is coordination the stat-wide tree plating effort. “Time is not neutral. We are so rapidly depleting the atmosphere, we are so rapidly changing the climate, that unless we start now the situation may well become irreversible.”Some movie stars were on hand for the tree planting ceremony. Actor Peter Cyote served as the master of ceremonies. “Unless the environmental movement comes into everybody’s life, in real simple activities, it’s not going to work. Planting a tree is real simple. So I wanted toparticipate in something that was really accessible to the citizen, just to everyday people, to children. So that as citizens we can do a lot.”After Peter Cyote introduced a few speakers and a couple of songs were sung, the ceremony moved over to a corner of the park where a group of youngsters planted a Copper Beech tree.Isobel Wade is the state coordinator for Campaign California Re-Leaf. Wade says the tree plantings are important because they will help clean up the carbon dioxide in the atmosphere, improve the environment and make neighborhoods more attractive, but Isobel Wade cautions it isn’t enough. “It’s one step in a combination of things. The other kinds of things that we can all be doing are being much more conscious about how we use energy in our home, whether we’re buying—ah—fuel efficient cars and products, whether we’re using Styrofoam when we don’t have to be, --ah—whether we’re turning off light bulbs when we—ah—leave the room—um—and just a variety of personal actions like recycling that we need to start thinking about and doing more.”Isobel Wade also says she’d love to see everyone in California’s urban arrears take the time to plant one tree and take care of the ones that are already growing.Key B1.planting single tree2.deflate Greenhouse Effect/ take CO23.real simple activities/ accessible to people/ citizens/ do a lot4.clean up CO2/ improve environment/ neighborhoods attractive5. a variety of personal actionsPart IIIWhen you go to the supermarket, can you resist using plastic bags For lot of us, probably won’t. What you eat out Can you guarantee not to use any plastic tableware And how about if someone asks you; can you recommend a replacement for plastic products Don’t say paper! Here is a new solution; biodegradable plastic!As everyone knows, plastic is a big environmental headache although it brings us much convenience. Like plastic bags, plastic food containers, and plastic tableware. But it is perhaps the most harmful of all our garbage because it does not easily break down in nature.A researcher form the Chinese Academy of Sciences, Ji Junhui says he and his colleagues have found a better solution.“When the PBS in the biodegradable plastic comes in contact with microorganisms or enzymes, the plastic structure will degrade into smaller pieces, and finally it turns into water and carbon dioxide. This is how the break-down process works.”PBS is a chemical component that is the key to this new biodegradable plastic. It can help the plastic degrade into non-polluting elements, so the broken-down plastic fragments can be absorbed by soil and water.PBS is not an entirely new product, however, this China-made biodegradable plastic is safer and more heat-resistant. According to Ji Jun-hui, testing has shown that 90% of this new biodegradable plastic can be degraded within 90 days. And it even takes a shorter period of time if it is buried in a dump rather than exposed to the air.Usually, biodegradable plastic food containers made in other countries will melt when thetemperature reaches 60 degree Celsius, while the Chinese product can retain its shape in up to 100 degrees.However, Ji Junhui says his-tech products often come at a higher price.“PBS product is a bit more expensive than ordinary plastic. Taking a plastic bowl as an example, the PBS bowl can be 20% more expensive than the current plastic bowl we use.”Some hotels and restaurants in Shanghai have already started using the new PBS biodegradable plastic food containers, and the product will be popularized in Beijing as well as in other big cities.It will play a role in the 2008 Olympic Games. Besides in the production of plastic food containers and tableware for the Games, PBS biodegradable plastic will also be used to make road signs, team cheering equipment like horns and mini flags, as well as trash bags, umbrellas and eyeglass frames.Probably in the near future, we will really be able to say “farewell” to plastic pollution.Key:OutlineI. headachenot easily bread downII.

Siemens is developing a cordless video telephone that includes a tiny camera and a high-resolution pixel color display. It can transmit at around 64 kilobits --- more than six times faster than current data transmission rates for mobile phones. Using an earpiece, callers hold the phones at arm’s length to maintain visual contact. Alternatively, the phone can be pointed at something else to allow the person on the other end to view it.2. Callwave, a start-up Internet telephone company based in Santa Barbara, California, has launched an Internet Answering Machine, free software that willanswer calls even when the user is on the Internet using the same telephone line. IAM, available at , takes massages and forwards them to the user, who can choose to listen instantly or save them for later.3. The Philip Genie, a lightweight mobile phone, can be operated by uttering a single word. When you type a name into the Genie’s keypad, the system asks whether you would like to assign a voice-dial tag to that name. Through “yes” or “no” prompts, the Genie compiles a list of up to 10 voice tags. The next time you want to call a person listed as one of these tags, just say that person’s name or a relevant code word.4. Ericsson’s iPulse software solution promises realtime messaging with family, friends and colleagues over any type of opt-in, opt-out system to protect privacy, users can see whether people who have agreed to be on a personal buddy list are currently online --- and where they are physically located. And as yet unnamed European phone company will be the first to launch the service in the next few weeks.5. American firm Palm Computing, part of 3Com, has released its Palm Ⅶ. Palm Computing has created a fast Internet messaging service for the Palm Ⅶbybuilding the Personal Query Assistant, a service allowing access to specially cut-down Internet sites which provide data such as flight schedules, sports scores,weather forecasts and news headlines. The device will be able to handle transactions like booking cinema tickets or making online stock trades.6. Motorola is working on a concept called the iRadio that will integrate music and personalized Internet services on a dash-board device. The iRadio could be programmed with the listening preferences of various family members, for example, so that it automatically finds the station that plays the desired music --- regardless of the car’s location. It could also alert the driver when the car is running low on fuel and then provide directions to the nearest gas station belonging to the driver’s preferred chain. The iRadio could also monitor selected stock prices and provide early warnings on the latest traffic jams, plusconvenient escape routes.7. New devices, such as Nokia’s 9110 Communicator, a combination of phone and Personal Digital Assistant, are almost ready on the market. But some customers feel the key-board and screen are too small and too complex for comfort. To get around these problems, Nokia’s 7110 mobile phone has a larger screen and is operated by a tracking ball in addition to a keyboard. The phone has a market among young people, who tend to send more text messages than they make mobile phone calls because text is less expensive.Part ⅡExperience with telephonesA. key words:amenity①Something that contributes to physical or material comfort舒适：使人身体或物质上感到舒适的事物②A feature that increases attractiveness or value, especially of a piece of real estate or a geographic location生活福利设施；便利设施：能够增加吸引力或价值的事物，特别是不动产或地理位置Vocabulary:PreteenBeing a child especially between the ages of 9 and 12; preadolescent青春期前的儿童：主要指9岁到12岁之间的儿童；接近青春期的儿童gizmoA mechanical device or part whose name is forgotten or unknown; a gadget机械装置，小物件：忘记了名字或不知道名称的机械装置或零件；新玩意儿hologramThe pattern produced on a photosensitive medium that has been exposed by holography and then photographically developed.全息图，综合衍射图：在感光材料上得到的图案，用全息照相术曝光，然后再用摄影术冲洗envisionTo picture in the mind; imagine想象：脑海中的图象；想象sleekSmooth and lustrous as if polished; glossy光滑的：象打磨过一样平滑而有光泽的；光滑OutlineⅠ. Estimated popularity of cellular phonesamong teenagersA. 5% of teenagers owning a cellular phoneB. 28% of parents with teenagers planning to buy a cell phone for their child within a yearⅡ. Different answers to the questions ofwhy this new teen accessory is neededA. Parents: an expansion of their protective eyeB. Teenagers: a gift of freedomⅢ. Impact of cellular phones on teenagerhabitsA. Spending more time on the phoneB. Being out of the house more oftenC. Staying in car when picking someone upⅣ. Price and calling plansA. Price: between $90 and $250B. Calling plans:1. Typical: $30 for 300 minutes2. Prepaid calling cards: $25, $50 or $753. Family calling plan: $50 a monthfor two lines of service and 200 minutes, and free calls between family membersTapescript:Cellular phones, once the toy of the rich business executive, are becoming a standard amenity for many teenagers and even preteens. The phones are marketed aggressively to a young audience, with gizmos such as alien holograms and toy kittens that hang off antennas and light up with each ring.Industry experts estimate that 5 percent of teenagers own a cellular phone, and one recent survey by a market research group found that 28 percent of parents with teenagers plan to buy a cell phone for their child within a year.But on the question of why this new teenaccessory is needed, the two generations are at opposite ends. Parents envision it as an expansion of their protective eye. Can’t locate the wandering teen? Just dial. Teenagers, on the other hand, see the cell phones as a gift of freedom, a device that instantly connects them to their friends, to every party an to the very latest piece of gossip.Many teenagers agreed that wearing cell phones has changed several of their habits. In addition to spending more time on the phone, they’re also out of the house more often. They find out from friends about last-minute get-togethers they otherwise would miss. Some said they no longer step out of their cars when picking someone up. Why bother ringing the doorbell when you can dial?Beepers became popular about a decade ago and raised some of the same issues between parents and their children. Butteenagers find the cell phones much more convenient. They’re also becoming particular about what kind of phone they have. Small and sleek is preferred, and the phone with a keypad that flips open is very cool.Most parents said these side effects are a price they’re willing to pay.Most cellular phones cost between $90 and $250, and the typical calling plan is $30 for 300 minutes. To tap into the teenager market, companies are selling prepaid calling cards for $25, $50 or $75. Most companies also have introduced family calling plans where teenagers and their parents pay about $50 a month for two lines of service and 200 minutes, and the calls between family members are free.Girls are getting the phones more than boys, mostly because parents tend to worry more about their daughters’ safety. But the trend is spreading to boys as well.B. key words:Vocabulary:Miracle Flakes for KidsCall BlockCall TraceAnonymous Call RejectionIdenta Ring Service1. What is the most annoying thing according to Mr. Rooney?People always call to make a sale when he’s busy doing something else.2. What is his suggestion to deal with the sales calls?Every time someone calls to sell something, the telephone company will automatically break in with its own announcement: “Mr. Rooney has a one-dollar charge for a sales call. If you wish to accept this charge, press star. If you don’t wish to pay, please hang up.”Tapescript:I make my living being annoyed by things, so I suppose I ought to thank those people who call to make a sale when I’m busy doing something else because nothing is more annoying. You know what I mean.“Yeah, OK. Hello!”“Hello, Mr. Rooney.”“What?”“This is a courtesy call. I’m not going to sell you anything.”“I was trying to call you today on behalfof Miracle Flakes for Kids, good day to you!”“There’s absolutely no application fees or anything like that, so you start saving money the first day.”“And no, I’m not trying to sell you any vocations.”The other day I had an idea that might be a solution to this problem we all have. It’s been a huge change in the last few years in our whole telephone system. Telephones have changed, companies have changed, and they’re all competing with each other an offering all sorts of new services.Here’s a telephone company brochure. It lists all these things that a phone company can do for you. Call Block, Call Trace, Anonymous Call Rejection, Identa Ring Service. They can do anything. So here is my idea: The phone company can do all those things, why don’t they do this: they know who the companies are, that are in thebusiness of calling the whole world to sell us something, so every time one of them calls, to sell something, the telephone company will automatically break in with its own announcement: “Mr. Rooney has a one-dollar charge for a sales call. If you wish to accept this charge, press star. If you don’t wish to pay, please hang up.”Part ⅢThe future of the phonekey words:multi-functional多功能的Vocabulary:convergeTo tend toward or approach an intersecting point会聚：趋向或靠拢于某一交叉点：slotA narrow opening; a groove or slit狭槽，缝：狭窄的开口；槽或狭长的裂缝：eg. a slot for coins in a vending machine; a mail slot自动售货机上的投币口；投信口intercomAn electronic intercommunication system, as between two rooms.内部通话系统：电子内部通信系统，如两个房间间的prismA transparent body of this form, often of glass and usually with triangular ends, usedfor separating white light passed through it into a spectrum or for reflecting beams of light棱镜：这种形状的透明体，多为玻璃制成，通常两端为三角形，用来分解穿过柱体的白光，使光束发生色散或用来反射光线Subscriber Identification Module (SIM)用户识别模块Deutsche Bank德国银行OutlineⅠ. The new era of personal communications--- a multi-functional communicator Main feature: capable of transmitting and receiving sound, video, images, data and textⅡ. The functions of phones in the futureA. TalkingB. Sending and receiving emailC. Taking part in video conferences anytime, anywhereD. Absorbing many of the key functions of the desktop computerE. New personalized services1. Trading stocks2. Gambling3. Shopping4. Buying theater and airline ticketsⅢ. Telecommunications revolutionA. developing mobile banking servicesB. Receiving all forms of electronic communication through a single deviceC. Receiving incoming TV images and other messages while on the moveD. Mobile videophones overtaking TV as the major source of visual informationTapescript:The mobile phone is set to become one of the central technologies of the 21st century. Within a few years, the mobile phone will evolve into a multi-functional communicator capable of transmitting and receiving not only sound, but also video, still images, data and text. A whole new era of personal communications is on the way.Thanks in part to the growth of wirelessnetworks, the telephone is converging with the personal computer and the television. Soon lightweight phones outfitted with high-resolution screens will be connected to satellites enabling people to talk, send and receive email, or take part in video conferences anytime, anywhere. These phones might also absorb many of the key functions of the desktop computer. Mobile devices are expected to be ideal for some of the new personalized services that are becoming available via the Internet, such as trading stocks, gambling, shopping and buying theater and airline tickets.The telecommunications revolution is already taking shape around the globe. In Europe, mobile phones are already being used for electronic commerce. Most phones contain a Subscriber Identification Module card to identify a user to the phone network. But the card could also facilitate limited financial transactions. Deutsche Bank andNokia, for example, are working together to develop mobile banking services. Some manufacturers plan to upgrade the SIM card to an all-in-one personal identification credit card.Another approach is to add a slot to mobile phones for a second smart card designed for mobile e-commerce. These cards could be used to make payments over the Internet or to pay for things like public transportation, movie tickets or drinks at a bar.It will soon be possible to receive almost all forms of electronic communication through a single device, most likely in a three-in-one phone that serves as a cordless at home, a cell phone on the road and an intercom at work. “The mobile phone will become increasingly multi-functional,” says Brughardt Scha-llenberger, vice president for technology and innovation at Siemens Information and Consumer Products inMunich. “Fingerprint technology and advanced speech recognition will ensure that only one or two authorized users will be able to operate it.”Images will be just as important as sound to the future of mobile communications. At British Tele-com’s research laboratories near Ipswich, England, engineers are evaluating how a tiny screen fitted to the side-frame of a pair of ordinary glasses can be linked to the human eye. The micro-PC is carried in a shoulder bag and connected to a tiny screen in the glass frame. The PC accepts incoming data in standard TV format via an aerial and converts it into PC format images. The image on the screen is reflected onto the human eye via a prism fitted onto the lens.A person wearing such glasses could be on the move while staying tuned in to incoming TV images, websites, video conferencing links or email messages.Some even suggest that mobile videophones could overtake television as the major source of visual information, giving the phrase “something to phone home about” a whole new meaning.。
