The United 18th7.No more than three days8. To get the Israelis and Palestinians back to the negotiating table9. 4 / Bosnian war / genocide in Rwanda / violence in East Timor Tapescript:Forty-eight of the ( United Nations Human Rights Commission's) 53 member nations voted to hold the emergency meeting. The United States cast the sole dissenting vote and Canada abstained. Three other countries did not vote.The special meeting will begin October 18th and will last for no more than three days.UN spokeswoman Marie Heuze says one purpose of the meeting is to try to learn how the cycle of violence between Israelis and Palestinians can be stopped."When you have such a high-profile for a crisis which is so dangerous, not only for the people in Palestine and in Israel, but in the region, thereis a fear -- and this is probably why there was a large consensus on this meeting to discuss the issue -- because the situation in this part of the world is so volatile, so dangerous, so important to control that everybody thinks that they have something to contribute."MsHeuze says she thinks the United Nations and the international community as a whole can play a constructive role in the present situation1. I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult, or expensive to accomplish... But, in a very real sense, it will not be one man going to the moon. If we make this judgment affirmatively, it will be an entire nation ... I believe we should go to the moon. (John F. Kennedy 25/05/1961)2. As he said many times, in many parts of this nation, to those he touched and who sought to touch him: "Some men see things as they are and say 'Why?' I dream things that never were and say 'Why not?'" (Edward M. Kennedy 08/06/1968)3. I have a dream that one day on the red hills of Georgia, sons of former slaves and the sons of former slave-owners will be able to sit down together at the table of brotherhood. I have a dream that one day, even the State of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character. (Rev. Martin Luther King, Jr. 28/08/1963)4. America needs a full-time President and a full-time Congress. Particularly at this time, with problems we face at home and abroad. To continue to fight through the months ahead for my personal vindication would almost totally absorb the time and attention of both the President and the Congress in a period when our entire focus should be on the great issues of peace abroad and prosperity without inflation at home. (Richard M. Nixon 08/08/1974)5. Thank you for opening up your minds and your hearts, for seeing the possibility of what we could do together for our children and for our future here in this state and in our nation. I am profoundly grateful to all of you for giving me the chance to serve you. I will... I will do everything I can to be worthy of your faith and trust and to honor the powerful example of Senator Daniel Patrick Moynihan ... I promise you tonight that I will reach across party lines to bring progress for all of New York's families. Today we voted as Democrats and Republicans. Tomorrow we begin again as New Yorkers ....

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 oil prices 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. But investment strategist Alan Skrainka says the longer-term looks better. "No one can guess what will happen to the market over the next month. But over the long-term, we think the market looks very good. If you're a long-term investor, this is a very good entry point for getting into the market because this is what you've been waiting for. All the fear and uncertainty in the marketplace is setting us up for some very good values in the market."Part III Voice mail may cost company’s businessAJud Jessup (TakeCare HMO): …personalized service…”high service”…getting a recording…efficient…cost effective……individual problems….Stanley Plogue (Plogue Research): …a fourth…let out…voice mail system…given up…Sandy hale (Pacific Bell):…bottom line…costs…more efficient…customer service operations…a valuable tool.B1.

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 ofthe 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 intheir 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 millionpeople 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 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.5.Traditional Chinese medicine says that good health is associatedwith the balance of Qi. Qi can be hindered or helped by yang andyin. 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/B1.Instructions / characteristic / DNA / another / organism / geneticallymodified organism / genetic engineering2.Artificial fertilizers / pest control / food / farming / artificial fertilizers/ half3.Genetic material / unrelated / another species / animal /plant / goingacross4.Animals / cows, goats and pigs / genetically changed / pharmaceuticaldrugs / farming5.Novel / 1797-1851/ scientist / subhuman / destroying / creation thatends up destroying the creator.Part II（答案见听力原文中的红色部分）In North Beach in San Francisco, where some pretty super food gets served every night.。

I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult, or expensive to accomplish... But, in a very real sense, it will not be one man going to the moon. If we make this judgment affirmatively, it will be an entire nation ... I believe we should go to the moon. (John F. Kennedy 25/05/1961)2. As he said many times, in many parts of this nation, to those he touched and who sought to touch him: "Some men see things as they are and say 'Why?' I dream things that never were and say 'Why not?'" (Edward M. Kennedy 08/06/1968)3. I have a dream that one day on the red hills of Georgia, sons of former slaves and the sons of former slave-owners will be able to sit down together at the table of brotherhood. I have a dream that one day, even the State of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character. (Rev. Martin Luther King, Jr.28/08/1963)4. America needs a full-time President and a full-time Congress. Particularly at this time, with problems we face at home and abroad. To continue to fight through the months ahead for my personal vindication would almost totally absorb the time and attention of both the President and the Congress in a period when our entire focus should be on the great issues of peace abroad and prosperity without inflation at home.

Officials from the UN Human Rights Commission will discuss the agenda toward the meeting on Wednesday.This is only the fifth time the commission has gone into emergency meeting to deal with a crisis situation. Previous sessions dealt with the Bosnian war, the genocide in Rwanda, and the violence in East Timor.Questions:1. How many members are there in the UN Human Rights Commission?2.

As he said many times, in many parts of this nation, to those he touched and who sought to touch him: "Some men see things as they are and say 'Why?' I dream things that never were and say 'Why not?'" (Edward M. Kennedy 08/06/1968)3. I have a dream that one day on the red hills of Georgia, sons of former slaves and the sons of former slave-owners will be able to sit down together at the table of brotherhood. I have a dream that one day, even the State of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin, but by the content of their character. (Rev. Martin Luther King, Jr.28/08/1963)4. America needs a full-time President and a full-time Congress. Particularly at this time, with problems we face at home and abroad. To continue to fight through the months ahead for my personal vindication would almost totally absorb the time and attention of both the President and the Congress in a period when our entire focus should be on the great issues of peace abroad and prosperity without inflation at home.

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. 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 oflive-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.B1.Foreign exchange rates:1 dollar = 1.733 German marks= 126.9 Japanese yen1 pound =1.624 dollarsShare IndexElectronic Data Systems (4th quarter): $ 0.70 per share ( $ 0.02 up)Tapescripts:1.

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 giants Citigroup and Bank of America. In fourth and fifth place are the British-based HSBC Banking Company andDaimler-Chrysler, the German-American auto-company. The companies are ranked with a composite formula, which includes total sales, profits, assets and marketcapitalization, 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.

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 computerchip-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 oil prices 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. But investment strategist Alan Skrainka says the longer-term looks better."No one can guess what will happen to the market over the next month. But over the long-term, we think the market looks very good. If you're a long-term investor, this is a very good entry point for getting into the market because this is what you've been waiting for.

Cantaloupes, mangos and carrots contain cancer-fighting carotenoids. And berries are bursting with flavonoids and ellagic acid ---- antioxidants that protect against cancer, ulcers, and viruses. Natalie recommends organic. “Organic fruits and vegetables have shown not only to have lower pesticide toxicities and lower pesticide levels, but also now have been shown to have higher phytochemical content.”Don’t forget the fatty fish or flaxseed ---- both are excellent source of Omega 3 fatty acids that inhibit the growth of cancer cells and boost the immune system, olive oil, which may reduce breast, prostate, or colon cancer, and soy.“soy ha s protective effects for heart disease as well as osteoporosis, potentially.”And finally onions, garlic, and shallots.

Many reports, researchers at Harvard Medical School say the significant reduction in salt intake can cut the chances of heart disease and strokes by a quarter. Here is our health correspondent, Adam Brimelow.It’s long bee n known that cutting salt can reduce blood pressure. But there has been much less evidence of what it means for cardiovascular disease, including heart attacks and strokes. The Harvard team followed up people with borderline high blood pressure, who had taken in part in two salt reduction studies, typically cutting intake from 10 to 7 gram s a day. The risk of developing cardiovascular disease over the next decade or so was cut by a quarter compared with those who did not reduce their salt intake. And their chances of dying from cardiovascular disease fell by 5/1. In developed countries such as the United States and the UK, the average adult daily salt intake is about 10 grams. Much of this is already in the food that people buy, including processed foods and bread. Many experts say no one should have more than 3 grams. They say the best way to cut salt, is to get away from fast food, check labels and have plenty of fresh fruit and vegetable. Adam Brimelow reporting.Part III Medical emergency 911A( 3 ) a.

There are 49 hospitals that have 24-hour emergency departments. Nine of those hospitals are specially designated shock trauma centers, and there's a sophisticated communication center that links the state's ambulances, helicopters, and the hospitals."A serious accident happens. Pre-hospital staff --paramedics, emergency medical technicians--through a sophisticated communication system know where and when the accident happened, and they are summoned immediately to provide the initial, quick, life-saving care."That's Dr Philip Militello. He's head of trauma surgery for the state system. If you have a serious injury anywhere in Maryland, this systemwill get you the right treatment with the least delay. What kind of help do you need? Where's the closest hospital? Should you go by ambulance or by helicopter? The answers to these questions come through sophisticated communications. The system springs into action with a telephone call to 911, your local emergency number anywhere in the state."Fire and rescue.”'If you're injured, your call is forwarded to the fire department's emergency rescue service. Based on the information you give them, they send a radio call for the nearest available help."He has been shot. Hold on while I dispatch an ambulance."A man has shot himself. The nearest available shock trauma ambulance is twenty minutes away. But a paramedic supervisor with some emergency medical equipment in his car responds to the radio call and arrives on the scene within nine minutes. The supervisor, Lieutenant Mike Fahey, is a nationally certified paramedic. He quietly talks to the patient while he bandages the bullet hole. Finding the patient's blood pressure alarmingly low, he immediately starts intravenous blood plasma. His movements are deliberate and his voice is calm."Come in. Take control of the situation. Remain calm. Chaos is contagious, and so is the calm that you have. When the patient looks up at you and you're calm, then you're reassuring. Then they calm down."The paramedic ambulance with advanced life support equipment arrives twelve minutes later, and Fahey's patient is loaded on a stretcher, ready to go. But the patient is in shock. If he stays in shock, he has a poor chance of survival. Inside the ambulance, they start another line of plasma and apply medical anti-shock trousers.Those are rubberized trousers to squeeze the blood from the legs back to the brain and other vital organs. Through radio communication everyone has agreed to send him by ambulance to the regional shock trauma center. It's only six minutes by land; it's available; and the regional center is equipped for his particular injury."They're putting on the trousers now. As soon as they get that, they'll be able to start going down the highway. '"If we can get the patient to the trauma center within twenty minutes, we go by land. If it's going to be longer than twenty minutes, we try to go by air."Captain Linda Sterling. She's Mike Fahey's boss at the local emergency medical service. When one of her paramedics needs a medevac helicopter, the request goes quickly to the SYSCOM, the statewide System Communication Center.Three large screens dominate the darkenedroom at SYSCOM. The right screen shows which hospital can take what kind of injury. The center screen shows the location of all medevac helicopters. And the one on the left shows the helicopter landing pad at the main shock trauma center. SYSCOM operations chief Andy Polavski tells us what's happening."Part of the operation here is the SYSCOM operation: system communications. They serve as the coordinators of the medevac activity in the stat e. This is the dispatch point for the State Police helicopters and the U.S. Park Police helicopters."SYSCOM can also connect by radio any paramedic in the state with any hospital or any emergency specialist. In shock trauma injuries, minutes can mean life or death. Maryland's communication system saves precious time by connecting citizens, ambulances, helicopters, and hospitals. Dr R. Adams Cowley, founder of the system, said, "If I can get you and stop your bleeding and restore your blood pressure within an hour of your accident, then I can probably save your life. 'Part IV Keeping the country healthyPart IV1.NH S’(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, cancer3. 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 proposals 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 the changes. 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.生词：Brain tissueNatural defense mechanismPsychological needsSide effectMedicationArtificial fertilizers / pest controlMaterial species物种迷迭香百里香（麝香）姜黄类结肠、直肠球芽甘蓝柑橘属科石碳酸（苯酚）类黄酮鞣花酸亚麻子青葱类。

Unit 5 Love and HelpPart I A. Tape scripts In the 1940s, the top seven problems for US schoolchildren were:1 talking in class2 chewing gum3 making noise4 running in the halls5 cutting in line6 dress code violations7 litteringToday’s young sters in US schools face a set of seven problems that are much more shocking:1 drug abuse2 alcohol abuse3 teen pregnancy4 suicide5 rape6 robbery7 assaultB Tape scriptsDogs that can retrieve cash from ATMs and empty washing machines help disabled people lead more independent lives, but can they also helpchange disruptive teenagers' behavior? A unique TV experiment, "Dog House", follows five unruly youngsters as they're taught to become dog trainers. The idea is simple. Kids really like dogs. But can the skills involved in training them patience, consistency, rewarding good behavior - give these teenagers the discipline they need in their own lives? The teens involved were put forward by local schools in West Sussex, who had run out of ideas of how to deal with them. Liam was typical - 14 years old, sullen, aggressive, foul mouthed and about to be permanently excluded from school. Allie, Rob and Ellie, had similar problems - they couldn't concentrate, they didn't like being told what to do and they had serious anger problems. Katrina was different. She was so shy that she had developed agoraphobia, she suffered from depression and had taken herself out of mainstream education. Gradually, working with the dogs began to have an impact on the kids. But, in order to fully appreciate the significance of what they were doing, they needed to meet the disabled people who benefited from having these dogs. The meetings had a profound impact on the teenagers. After meeting Eileen Hobson and her dog Sailor, Liam changed his ways and his unlikely friendship with severely disabled wheelchair user Eileen blossomed. Two months into the course Liam began to connect to the dogs too - particularly a young yellow Labrador called Aero. The relationship flourished so much that the dog often knew instinctively what the teenager wanted him to do beforehe'd even asked. "He just knows,” says Liam. Liam's school noticed a huge change in his whole outlook. His teacher Nick Brown said, “More than anything I see a confident and happy young man. It's been superb. "C Tape scriptsA new food Policy study predicts malnutrition over the next 20 years aggressive action. The International Food Policy Research Institute in Washington says international efforts to reduce the number of malnourished children in world have been awfully inadequate. It predicts that despite a 20 percent decline in the number of malnourished children by 2020, L32 million still be underfed. The cost of cutting child malnutrition in half by would be an extra 10 billion dollars a year. Twenty-five billion dollars now invested in developing countries annually to boost farm productivity secure clean water sources, develop world infrastructure, and I education and health. Ten billion dollars more is a scant amount. Not all regions face equally bleak food futures. Latin America will visually eliminate child malnutrition by 2020, and China will cut it in half. But the Food Policy Organization says India will continue to have one third of the world's underfed children. And Africa will see an 18 percent increase unless action is taken.Part II Anti-AIDS campaignA.TapescriptPredicting the future is risky business for a scientist. It is safe to say,however, that the global AIDS epidemic will get much worse before it gets any better. Sadly, this modern plague will be with us for several generations, despite major scientific advances. As of January 2000, the AIDS epidemic has claimed 15 million lives and left 40 million people living with a viral infection that slowly but relentlessly erodes the immune system. Accounting for more than 3 million deaths in the past year alone, the AIDS virus has become the deadliest microbe in the world, more lethal than even TB and malaria. There are 34 developing countries where the prevalence of this infection is 2 percent or greater. In Africa nearly a dozen countries have a rate higher than 10 percent, including four southern African nations in which a quarter of the people are infected. And the situation continues to worsen; more than 6 million new infections appeared in L999. This is like condemning 16,000 people each day to a slow and miserable death. Fortunately, the AIDS story has not been all gloom and doom. Less than two years after AIDS was recognized, the guilty agent – human immunodeficiency virus, or HIV was identified. We now know more about HIV than about any other virus, and 14 AIDS drugs have been developed and licensed in the US and Western Europe. The epidemic continues to rage, however, in South America, Eastern Europe and sub-Saharan Africa. By the year 2025, AIDS will be by far the major killer of young Africans, decreasing life expectancy to as low as 40 years in some countries and single-handedly erasing the publichealth gains of the past 50 years. It is Asia, with its huge population at risk, that will have the biggest impact on the global spread of AIDS. The magnitude of the pandemic could range from 100 million to t billion, depending largely on what happens in India and China. Four million people have already become HIV-positive in India, and infection is likely to reach several percent in a population of I billion. An explosive AIDS epidemic in the US is unlikely. Instead, HIV infection will continue to fester in about 0. 5 percent of the population. A cure for AIDS by the year 2025 is not inconceivable. But constrained by economic reality, these therapeutic advances will have only limited benefit outside the US and Western Europe. A vaccine is our only real hope to avert disaster unparalleled in medical history. A large, concerted effort of research was launched three years ago in the US and hints of promising strategies are emerging from experiments in monkeys. But even if an AIDS vaccine is developed before 2025, it will require an extraordinary effort of political will among our leaders to get to the people who need it most.B.Tape scriptsMost students in the nation's public schools receive some form of sex education. But it's not always clear what schools are teaching or what educators, parents and children think about it. Kids are learning a lot more about sex than many people think, and parents want schools to teach them even more. Sex education usually starts in elementary schoolas part of a health curriculum. By the l2th grade, 90 percent of all public school students have taken at least two sex education courses. "A large majority are providing some information about HIY /AIDS. Most are talking about abstinence, providing messages about the importance of waiting to have sex." Beginning in the 7th and 8th grades, over half of the 1, 500 junior high and high school students surveyed said they were taught how to deal with peer pressure to have sex, where to get and how to use contraception, how to talk to a partner about safe sex, and where to get tested for sexually transmitted diseases, including HIV/AIDS. Although a third of the schools in the study focused exclusively on abstinence, the main message in about B0 percent of all sex education courses is this: young people should wait to have sex, but if they don't, they should use birth control and practice safe sex. But even fear of HM AIDS and sexually transmitted diseases or getting pregnant doesn't always stop kids from having sex. Well, our parents know this? "I think many parents have no idea what's actu ally happening in the school.” Parents should have the right to keep their children out of sex education classes that teach things that they don't agree with. Many schools do notify parents when their child starts sex education, but in most cases, schools don't need the parents' permission. Instead 40 percent of schools invited parents to attend sex education classes. A surprising 22 percent of schools did not notify parents at all. Still a clear majority of parentswanted to see more sex education in schools, not less. And they don't just want abstinence or the basics of human reproduction. Over 90 percent of parents want schools to cover HMAIDS and sexually transmitted diseases, rape, safe sex. Most said condoms and birth control needed to be discussed. They thought abortion was an appropriate topic, and thought that homosexuality should be included, too.Researchers say this surprising level of support for more sex education may be due to the fact that parents don't talk to their children about sex, so they want schools to do it. We have a third of the students surveyed cited parents as a source of information about sex. Sixty-one percent said that most of what they do know about sex they learned from their friends, followed by television, movies and magazines. The message that educators should note is that there is a need for more sex education not less, and more practical approach to the dangers and risks of sexual behavior.Part III Tape scriptsInternet communication can be dangerous for adults, and children re even more vulnerable. Homayra Sellier and Parry Aftab work with an organization called" Innocence in Danger. “It’s a world citizen's movement to protect children from sexual abuse and pedophilia on the Internet. "Pan1r, it would seem that in the United States there would be lots f laws protecting children against abuse on the Internet.” Well, there are laws to protect children from abuse, online and offline; they applyequally in both places. The problem is that children use the Internet and far more often know more about it than their parents do. But, the things we usually use to teach our children how to stay safe in shopping malls, and on streets and in life, don't ordinarily apply online, because parents just don't understand it well enough to set the rules, for the pedophiles are using this technology and the fact that they can hide behind anonymity and pretend they're another child to lure our children in ways that we are not yet prepared to teach our children to avoid. " One of the goals of UNESCO is to make sure all children have access to the Internet, and yet in doing this you want to make sure they have access safely. It sounds like a huge task to get companies and countries involved in doing this. "It is a huge task, I do agree with you. It is a worldwide problem and that is the reason why our action has to be global and international. I think even though it's a very big task, we are little by little going to get there, with everybody's help. " "What are some of the other dangers, I mean, we've talked a little bit or alluded to child pornography, how does that impact children?" “Often the pedophiles use child pornography to desensitize our children. So, if they're setting a conversation up, and they send a photo to a ten-year-old of another ten-year-old engaged in sexual activity, thirteen-year-old now thinks that perhaps it's not so unusual and it's not so contraband for them to engage in sexual activity as well. And that's typically how it's used. " “And is . . . is there one other aspect r egardinghate email or hate websites?" “I think the dangerous . . . the biggest danger obviously is not from information, but from people who want to hurt children. Uh, but there’re hate sites and bigotry and intolerance, there are sites where children can order guns, and poison, and drugs, and tobacco and alcohol, there’re sites that teach our children how to build bombs and unfortunately they are building bombs with this information, and there's a lot of misinformation and cults, and that is quite dangerous, I mean, in addition, we . . . our children may be exposed to information that parents would prefer they're not exposed to. Because of this, what we need to do is to arm parents with the tools they need to educate their children and keep them safe, and make sure that law enforcement does what they canto clean up the criminal activities online. " "What are your specific tasks in the United States?" “Three prongs are making sure that children are safe from predators; that we try to do what we can to control child pornography; we work closely with law enforcement; we get all of the Internet service providers and all of the Internet industry on board. And I should tell you that most of them are there already as part of . . . as committed members of the National Action Committee. We're also committed to helping schools and teachers and libraries to get the most out of the Internet by learning how-to use it and developing safety programs and education programs for parents so that parents will let their children be on the Internet and help them deal with the risks they'll faceday to day from predators, and from kooks and crackpots and misinformation and hate that they will face, so that we're here to empower the parents to help keep the children safe. "Part IVKen Schuler- a husband, a father, and an artist. He also saved another person’s life in the most remarkable way. Schuler is the first known person to step forward and donate part of his liver to a stranger. It happened like this. He heard this man plead for his daughter's life. "I'm hoping that there'd be somebody out there that would be kind enough to help my daughter.” (Claude Smallwood, Debbie Parker's father) Thirty-nine-year-old Debbie Parker's liver had been destroyed by hepatitis C. The wife and mother of three needed a liver transplant. Without one, she would die within days. Because the list for a liver formal cadaver was so long, doctors suggested a new, experimental option living-donor liver transplant. That is, a living person can give Debbie apiece of his or her liver. "They said they were looking for a B-positive donor, which ...that's what I am. And as soon as I heard that, I looked at my wife and said, 'I would do that in a heartbeat,' got up, and made the phone call. We met in the waiting room, and we were both having blood work done. And that was probably ... probably one of the best days in my life. "(Ken Schuler, liver donor) “I tapped him on the shoulder, and I said, ' Are you Ken Schuler? ' And he goes, 'Yes, I am,'and I said, 'I'm Debbie Parker.' And we just embraced right there, and the whole waiting room started crying. "(Debbie Parker, liver recipient) "I was trying to save somebody's life, and she was, you know, wanting me to save her life. And when somebody hugs you around the neck like that, it's ... it's ... it still gets to me, thinking about it. " ( Ken Schuler)But even at that point, they couldn't be sure if Ken would qualify as a donor. Earlier, Debbie's brother had come forward to be a donor, but he did not qualify medically. “It is a highly risky it's a risky operation. " ( Dr Amadeo Marcos, Medical College of Virginia) Dr Amadeo Marcos did the first unrelated living-donor liver transplant a year ago and has done 27 since then. Most have been between husbands and wives. "We were forced to do this technique, because we don't ... we ourselves did not have enough livers for our own list, and our patients were ... were dying.” (Dr Amadeo Marcos) There are only a handful of centers in the United States offering living-donor liver transplants in adults. If more widely used, doctors say, it’s an option that can make a significant dent in the organ shortage. But, ethically, can you ask someone to undertake the risk of donating part of their liver? "I think you can. I don't think it's unethical to have a wife volunteer to have a piece of her liver given to her child or to her husband. It's probably not even unethical to do it for friends. " ( Dr Arthur Caplan, Center for Bioethics) "But you are operating on a healthy person who doesn't have anything wrong with him, and I think we should alwaysremember that.” (Dr Thomas Heffron, Emory and Egleston-Scottish Rite Transplant Programs) Ken Schuler says he was not concerned about the possible risk of dying or becoming disabled. One week after Ken gave part of his liver to Debbie, his liver regenerated, or grew back to its original size." He's my life preserver. He doesn't like me to call him a hero, so I call him my life preserver. “(Debbie Parker) “What does it feel like to be able to do that for another person like that?" (Cl,fN Reporter) "Oh, this is the hard part. It's ... it's the best thing, you know, I’ve ever done. . . it gives you a feeling that you can't describe. And the more people, excuse me, the more people we can get to . . . to do…this .. . They ...they don't understand what they're missing.

大学英语精读第3册第5课课文翻译及课后答案课文翻译妈妈哭的那天很久前一个阴暗的冬天，我放学回家，心中充满着期待。
我腋下夹着一本我所喜爱的刚出版的体育杂志，而且整个房子将只有我一个人。
爸爸还没下班，妹妹不在家，妈妈刚找到一份新工作，在一小时内是不会回家的，我跳上台阶，冲进起居室，啪的一声打开电灯。
我眼前出现的景象使我惊呆了。
妈妈紧缩着身子。
手捂着脸，坐在沙发的一端，她在哭。
我以前从没见她哭过。
我小心地走近她，把手放在她肩上。
“妈”我说，“怎么了？”妈妈长叹一口气，强作微笑。
“没什么，真的。
没什么大不了的事。
只是我要失去这份新工作了。
我字打的不够快。
”“但你才上三天班，”我说，“你会赶上的。
”我重复了妈妈对我说过的一百遍的那句话。
每当我学什么或做什么重要事情而遇到麻烦时，妈常这样对我说。
“不行了，”妈妈神色黯淡地对我说。
“过去我常说只要我下决心，什么事我都能干好。
现在我仍然认为在多数情况下我能做到。
但是，打字这事我做不到啦。
”我无能为力，十分尴尬。
那时我16岁，仍然认为妈妈能做任何事。
几年前，当我们卖掉农场，搬到城里来住的时候，妈妈决定开一所日托所。
她没受过这方面的训练，但这并不妨碍她。
她参加幼托函授课学习，做练习，六个月后就正式获得从事这项工作的资格了。
不久后，她不但招满了生，而且还有许多孩子等着注册。
我认为这是理所当然的，是妈妈能力的体现。
但是不管是日托所还是后来爸妈买的汽车旅馆都无法提供足够的钱送我和妹妹上大学。
两年后我就要准备上大学了。
再过三年，妹妹也想上大学。
时间过得真快。
妈妈想尽了一切方法存钱。
很明显，爸爸不可能比他现在干得更多---除了一份全日制工作外，还要耕种80英亩地。
在我们卖掉汽车旅馆几个月后，妈弄回家一台旧式打字机。
这台打字机跳字，键盘也很松。
那天吃饭时，我说这台打字是“废物一件”。
“我们只买得起这个,”妈妈说。
“这对练打字是够好的了。
”从那天开始，只要桌子一收拾，碗一洗，妈妈就会消失到她的缝纫房里练习打字。

Research now s hows that some foods, including tomatoes, onions, garlic, and olive oil ---- are among the super foods. Super foods are packed with powerful chemicals that may offer your body great protection against chronic disease“Including cancer, obesity, heart dise ase. Vibrantly colored red, yellow, orange and green all giving you different types of phytochemicals.”Natalie Ledsma is a registered dietician at U. C. S. F. she says compounds found in super foods --- called phytochemicals ---- can reduce the risk of cancer, boost the immune system, and protect the heart. She showed us what everyone should try to eat each week for optimal health.One her shoppinglist? Herbs!“Dark green ones (herbs), like rosemary and thyme, and any intensly colored spice, like turmeric or red pepper.”“Both of those have anti-inflammatory properties.”Turmeric many reduce the risk of leukemia, skin, and liver cancers. Hot peppers may reduce the risk of colon, stomach, and rectal cancers. Also on the list: green veggies. But not just nay green veggy.“Brussels sprouts are part of the cruciferous vegetable family that has significant anti-cancer properties, and that family also has a very favorable effect on hormone metabolism.”Other cruciferous veggies include cabbage, broccoli, and cauliflower. And don’t forget the tomato.“it is probably the best source of lycopene, which is one of the phytochemicals that has shown significant anticancer properties, especially with prostate andpotentially lung and breast cancer as well.”As for fruit, citrus contains Vitamins C, limonoids, and phenols, which inactivate cancer cells and strengthen the immune system. Cantaloupes,mangos and carrots contain cancer-fighting carotenoids. And berries are bursting with flavonoids and ellagic acid ---- antioxidants that protect against cancer, ulcers, and viruses. Natalie recommends organic.“Organic fruits and vegetables have shown not only to have lower pesticide toxicities and lower pesticide levels, but also now have been shown to have higher phytochemical content.”Don’t forget the fatty fish or flaxseed---- both are excellent source of Omega 3 fatty acids that inhibit the growth of cancer cells and boost the immune system, olive oil, which may reduce breast, prostate, or colon cancer, and soy.“soy has protective effects for heart disease as well as osteoporosis, potentially.”And finally onions, garlic, and shallots. They may protect the heart fight cancer, and help with asthma.BI.Harvard Medical SchoolII.Borderline high blood pressureIII.10 /7IV.Cardiovascular / by a quarterChances of dying from cardiovascular disease falling by 5/1V.A: no more than 3 gramsB: fast foodC: labelsD: fresh fruit and vegetables听力原文：Salt is crucial to our health, but too much of it can put human at risk from high blood pressure, heart disease and stroke. Many reports, researchers at Harvard Medical School say the significant reduction in salt intake can cut the chances of heart disease and strokes by a quarter. Here is our health correspondent, Adam Brimelow.It’s long been known that cutting salt can reduce blood pressure. But there has been much less evidence of what it means for cardiovascular disease, including heart attacks and strokes. The Harvard team followed up people with borderline high blood pressure, who had taken in part in two salt reduction studies, typically cutting intake from 10 to 7 gram s a day. The risk of developing cardiovascular disease over the next decade or so was cut by a quarter compared with those who did not reduce their salt intake. And their chances of dying from cardiovascular disease fell by 5/1. In developed countries such as the United States and the UK, the average adult daily salt intake is about 10 grams. Much of this is already in the food that people buy, including processed foods and bread. Many experts say no one should have more than 3 grams. They say the best way to cut salt, is to get away from fast food, check labels and have plenty of fresh fruit and vegetable. Adam Brimelow reporting.Part III Medical emergency 911A( 3 ) a.

Tapescript 听力原文：Maryland may be a small state, but it's a major player in developing emergency medical services. There are 49 hospitals that have 24-hour emergency departments. Nine of those hospitals are specially designated shock trauma centers, and there's a sophisticated communication center that links the state's ambulances, helicopters, and the hospitals."A serious accident happens. Pre-hospital staff --paramedics, emergency medical technicians--through a sophisticated communication system know where and when the accident happened, and they are summoned immediately to provide the initial, quick, life-saving care."That's Dr Philip Militello. He's head of trauma surgery for the state system. If you have a serious injury anywhere in Maryland, this system will get you the right treatment with the least delay. What kind of help do you need? Where's the closest hospital? Should you go by ambulance or by helicopter? The answers to these questions come through sophisticated communications. The system springs into action with a telephone call to 911, your local emergency number anywhere in the state. "Fire and rescue.”'If you're injured, your call is forwarded to the fire department's emergency rescue service. Based on the information you give them, they send a radio call for the nearest available help."He has been shot. Hold on while I dispatch an ambulance."A man has shot himself. The nearest available shock trauma ambulance is twenty minutes away. But a paramedic supervisor with some emergency medical equipment in his car responds to the radio call and arrives on the scene within nine minutes. The supervisor, Lieutenant Mike Fahey, is a nationally certified paramedic. He quietly talks to the patient while he bandages the bullet hole. Finding the patient's blood pressure alarmingly low, he immediately starts intravenous blood plasma. Hismovements are deliberate and his voice is calm."Come in. Take control of the situation. Remain calm. Chaos is contagious, and so is the calm that you have. When the patient looks up at you and you're calm, then you're reassuring. Then they calm down."The paramedic ambulance with advanced life support equipment arrives twelve minutes later, and Fahey's patient is loaded on a stretcher, ready to go. But the patient is in shock. If he stays in shock, he has a poor chance of survival. Inside the ambulance, they start another line of plasma and apply medical anti-shock trousers. Those are rubberized trousers to squeeze the blood from the legs back to the brain and other vital organs. Through radio communication everyone has agreed to send him by ambulance to the regional shock trauma center. It's only six minutes by land; it's available; and the regional center is equipped for his particular injury."They're putting on the trousers now. As soon as they get that, they'll be able to start going down the highway. '"If we can get the patient to the trauma center within twenty minutes, we go by land. If it's going to be longer than twenty minutes, we try to go by air."Captain Linda Sterling. She's Mike Fahey's boss at the local emergency medical service. When one of her paramedics needs a medevac helicopter, the request goes quickly to the SYSCOM, the statewide System Communication Center.Three large screens dominate the darkened room at SYSCOM. The right screen shows which hospital can take what kind of injury. The center screen shows the location of all medevac helicopters. And the one on the left shows the helicopter landing pad at the main shock trauma center. SYSCOM operations chief Andy Polavski tells us what's happening."Part of the operation here is the SYSCOM operation: system communications. They serve as the coordinators of the medevac activity in the stat e. This is the dispatch point for the State Police helicopters and the U.S. Park Police helicopters." SYSCOM can also connect by radio any paramedic in the state with any hospital or any emergency specialist. In shock trauma injuries, minutes can mean life or death. Maryland's communication system saves precious time by connecting citizens, ambulances, helicopters, and hospitals. Dr R. Adams Cowley, founder of the system, said, "If I can get you and stop your bleeding and restore your blood pressure within an hour of your accident, then I can probably save your life. 'Part IV Keeping the country healthyPart IV1.NHS’(英国国民健康保险制度) greater focus on prevention 1. agimmick2.a: increased screening 2. propertimetablee.g. heart disease, stroke, cancer 3.treatmentb: the most vulnerable 4.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 proposals 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 the changes. 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.生词：Brain tissueNatural defense mechanismPsychological needsSide effectMedicationArtificial fertilizers / pest controlMaterial species物种迷迭香百里香（麝香）姜黄类结肠、直肠球芽甘蓝柑橘属科石碳酸（苯酚）类黄酮鞣花酸亚麻子青葱类。
