Text 4 As the nation experiences one of the worst flu seasons in years,thousands of Americans have already died from influenza,according to the U.S.Centers for Disease Control and Prevention.Though the season peaked in February,the CDC recently warned that we should prepare for a second wave of cases to hit before we emerge from the season entirely.Now,it appears more than 50,000 could die from the flu before the season ends.Perhaps most troubling is that this year marks a century since the deadliest viral outbreak in human history,which claimed the lives of 670,000 American men,women and children and as many as 50 to 100 million people worldwide.Among the lessons medical researchers gleaned from the catastrophic event is the critical importance of getting vaccinated.It's a lesson that much of the public continues to ignore,even as our scientific understanding of communicable diseases continues to grow.-The strain in tlus flu season,H3N2,is particularly nasty.It's similar to the HINl strain that set off the 1918 influenza pandemic,and it has resulted in high rates of death,particularly among the elderly.Researchers have struggled to create effective vaccines for the H3N2 strain;this year's flu vaccine is only about 36 percent effective at protecting against the virus,compared to an average of 45 percent over the past seven years.Nonetheless,it does provide some protection,and the unvaccinated are hit much harder without it.Earlier this year,a healthy young man from Pittsburgh did not get vaccinated and died soon afier getting the flu.While low vaccine efficacy means that those who get vaccinated can still contract the flu,it remains common sense and good civic behavior to get vaccinated.As a result of herd immunity,even low efficacy vaccines are enough to curb a pandemic from happening if vaccination rates are high.Flu vaccines did not exist during the pandemic of 1918,which is why it was so deadly.Yet year after year few Americans bother to get vaccinated.In economic terms,the herd immunity benefits of vaccination are a"public good."If I am vaccinated,I cannot exclude anyone from the herd immunity that I now offer.Similarly,someone enjoying my herd immunity does not diminish someone else's ability to enjoy my herd immunity.What typically happens when a public good like the flu vaccine is available is that many,perhaps most,people underinvest.They free ride off other people who get the vaccine.If too many people opt out of vaccination,communities become wlnerable to flu epidemics.According to the CDC,only 38 percent of the population chose to get vaccinated as ofNovember 2017.Low rates ofvaccination are particularly dangerous for children and the elderly,who are especially susceptible to influenza.As individuals,we have veU little control over the strain of the flu that emerges in a given year,or the efficacy of a vaccine,but we do have complete control over whether we get vaccinated.The public's response to a bad fiu outbreak or to low vaccine efficacy should be an increase in flu vaccinations,not a decrease.38.According to the text,there is no doubt about the infiuenza vaccines that

A.low efficacy vaccines can also help with vaccination accepted.
B.those who get vaccinated would not be infected.
C.the idea of herd immunity is a common sense.
D.many Americans are willing to get vaccinated.

1.Passage TwoQuestions 26 to 30 are based on the following passage.Scientists have established that influenza viruses taken from man can cause the disease in animals. In addition,man can catch the disease from animals. In fact,a great number of wild birds seem to carry the virus without showing any evidence of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom,a group that has been on the earth 100 million years and is able to carry the virus without contracting the disease. These are even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombinations is a great variety of strains constraining different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus form. a lower animal to produce an entirely new spike.Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig,for example,to produce a new strain which is transmitted to man.According to the passage,scientists have discovered that influenza viruses______.A. cause ill health in wild birdsB. do not always cause symptoms in birdsC. are rarely present in wild birdsD. change when transferred from animals to man

2.Text 1 The influenza season is just getting started in the United States,and it already promises to be more severe than usual.Hospital emergency rooms are filling up with flu sufferers,and pharmacies have reported medicine shortages.Twelve children had died as of last month.To make matters worse,in Australia,which experienced its flu season four to six months ago,the current vaccine appeared to be only about 10 percent effective against tlus year's dominant strain.Yet as bad as this winter's epidemic is,it won't compare with the flu pandemic that is almost certainly on the horizon if we don't dedicate energy and resources to a universal vaccine.The 1918 Spanish flu epidemic killed 50 million t0 100 million around the globe.Given the century of medical progress since then,one might conclude that we are far better prepared today to deal with such a worldwide catastrophe.Unfortunately,the opposite is true.The world has about four times the number of inhabitants it did in 1918,including hundreds of millions of people,poultry and pigs living close together.This provides a potent biologic mixing bowl and natural influenza virus mutation factory.When a pandemic does strike,we'll be in trouble in part because American hospitals and pharruacies keep in stock no more than a few days supply of most lifesaving drugs,almost all of which are made in Asia.Worldwide manufacturing and shipping are highly susceptible to disruption,which could mean shortages in many areas.A 1918-type influenza pandemic could cause ruin on the order of what the Black Death did t0 14th-century Europe,but on a global scale.Our current vaccines are based on 1940s research.Limited global manufacturing capacity combined with the five to six months it takes to make these vaccines mean many people would never even have a chance to be vaccinated.Little is being done to aggressively change this unacceptable situation.We will have worldwide flu pandemics.Only their severity is unknown.The only real solution is a universal vaccine that effectively attacks all influenza A strains,with reliable protection lasting for years,like other modem vaccines.Although the National Institutes of Health has publicly declared developing a vaccine a priority,it has only about$32 million this year specifically for such research.The Biomedical Advanced Research and Development Authority,the other federal agency responsible for developing and making available new vaccines for emergency response,has in fiscal year 2017 0nly a single project for$43 million supporting game-changing infiuenza vaccines.By contrast,the search for an H.I,V.vaccine-still a scientific long shot-receives Sl billion annually.We estimate that intemational govemments,vaccine manufacturers and the philanthropic community must make a similar commitment to influenza vaccine research if the kind of vaccine we need is to developed in the next 10 years.But there is no apparent effort to make these vaccines a priority in the current administration 25.Which ofthe following would be the best title for the text?A.We Desperately Need a Universal Vaccine B.Shortages ofVaccines Need Solving C.To Fully Prepared for a Worldwide Catastrophe D.Measures We Should Take to Deal With Influenza

3.Text 3 In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association(NBA)listed at over seven feet.If he had played last season,however,he would have been one of 42.The bodies playing major professional sports have changed dramatically over the years,and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger,longer frames.The trend in sports,though,may be obscuring an unrecognized reality:Americans have generally stopped growing.Though typically about two inches taller now than 140 years ago,today’s people–especially those born to families who have lived in the U.S.for many generations–apparently reached their limit in the early 1960s.And they aren’t likely to get any taller.“In the general population today,at this genetic,environmental level,we’ve pretty much gone as far as we can go,”says anthropologist William Cameron Chumlea of Wright State University.In the case of NBA players,their increase in height appears to result from the increasingly common practice of recruiting players from all over the world.Growth,which rarely continues beyond the age of 20,demands calories and nutrients–notably,protein–to feed expanding tissues.At the start of the 20th century,under-nutrition and childhood infections got in the way.But as diet and health improved,children and adolescents have,on average,increased in height by about an inch and a half every 20 years,a pattern known as the secular trend in height.Yet according to the Centers for Disease Control and Prevention,average height–5′9″for men,5′4″for women–hasn’t really changed since 1960.Genetically speaking,there are advantages to avoiding substantial height.During childbirth,larger babies have more difficulty passing through the birth canal.Moreover,even though humans have been upright for millions of years,our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs.“There are some real constraints that are set by the genetic architecture of the individual organism,”says anthropologist William Leonard of Northwestern University.Genetic maximums can change,but don’t expect this to happen soon.ClaireC.Gordon,senior anthropologist at the Army Research Center in Natick,Mass.,ensures that 90 percent of the uniforms and workstations fit recruits without alteration.She says that,unlike those for basketball,the length of military uniforms has not changed for some time.And if you need to predict human height in the near future to design a piece of equipment,Gordon says that by and large,“you could use today’s data and feel fairly confident.”35.The text intends to tell us thatA.the change of human height follows a cyclic pattern. B.human height is becoming even more predictable. C.Americans have reached their genetic growth limit. D.the genetic pattern of Americans has altered.

    Flu Shots Or Not?
    It sounded like a good idea when New York City's mayor,Rudollph Giuliani,advised New Yorkers recently to get a flu shot.After all,20,000 Americans each year die of influenza. And this year in particular,the mayor suggested,getting a flu shot might be an especially good idea, since it could help doctors distinguish between flu and the deadly inhalational(吸入的)form of anthrax(炭疽).How? Both anthrax and flu exhibit strikingly similar symptoms-fever, chills and muscle aches-in the early days of the infection.Physicians would be quick to suspect anthrax in anyone who was vaccinated(接种疫苗)against flu and still developed fever and chills. That would give them a better chance to identify any new victims of terror while their infection was still in its earliest,most treatable stages.
    Or so the mayor's reasoning went. Unfortunately,there are a couple of problems with his log-ic .For one thing,getting vaccinated against influenza doesn't guarantee you won't get sick .Al-though highly effective,the flu vaccine(疫苗)protects against only the dominant types of the dis-ease and even then does not provide 100% protection.It takes a couple of weeks for your body to respond to the vaccine with a sufficient number of antibodies(抗体).Each year thousands of
    Americans who get the vaccine nevertheless still get the flu.
    There are also plenty of reasons you might develop fever,chills and muscle aches that have nothing to do with either anthrax or flu .Indeed,doctors estimate that more than 80%of all flu-like illnesses each winter are caused by other groups of viruses.Getting vaccinated against flu can't protect you against suffering from these other illnesses.
    In the worst case,asking all healthy adults to get vaccinated could actually have the opposite effect to the one intended,leading to even more deaths if it means we run out of shots for those who are most vulnerable to the infection.Already there have been delays in getting this year's shipment of vaccine to clinics and doctor's offices.Those who should be at the front of the line in-clude folks who are 65 or older,nursing-home residents and adults and children with chronic health problems as well as anyone who cares for or lives with such people .Flu shots are also im- portant for men and women whose immune system is weakened by HIV(艾滋病病毒)or other conditions.
    The best reason to get the flu vaccine is that it proteets against most flus-not that you're worried about getting anthrax.While inhalational anthrax has killed only five people so far,many more could be at risk from flu-related complications.There's no need to worsen the tragedy by making this year's influenza epidemic any worse.

    Or so the mayor's reasoning went. Unfortunately,there are a couple of problems with his log-ic .For one thing,getting vaccinated against influenza doesn't guarantee you won't get sick .Al-though highly effective,the flu vaccine(疫苗)protects against only the dominant types of the dis-ease and even then does not provide 100% protection.It takes a couple of weeks for your body to respond to the vaccine with a sufficient number of antibodies(抗体).Each year thousands of
    Americans who get the vaccine nevertheless still get the flu.
    There are also plenty of reasons you might develop fever,chills and muscle aches that have nothing to do with either anthrax or flu .Indeed,doctors estimate that more than 80%of all flu-like illnesses each winter are caused by other groups of viruses.Getting vaccinated against flu can't protect you against suffering from these other illnesses.
    In the worst case,asking all healthy adults to get vaccinated could actually have the opposite effect to the one intended,leading to even more deaths if it means we run out of shots for those who are most vulnerable to the infection.Already there have been delays in getting this year's shipment of vaccine to clinics and doctor's offices.Those who should be at the front of the line in-clude folks who are 65 or older,nursing-home residents and adults and children with chronic health problems as well as anyone who cares for or lives with such people .Flu shots are also im- portant for men and women whose immune system is weakened by HIV(艾滋病病毒)or other conditions.

    Flu Shots Or Not?
    It sounded like a good idea when New York City's mayor,Rudollph Giuliani,advised New Yorkers recently to get a flu shot.After all,20,000 Americans each year die of influenza. And this year in particular,the mayor suggested,getting a flu shot might be an especially good idea, since it could help doctors distinguish between flu and the deadly inhalational(吸入的)form of anthrax(炭疽).How? Both anthrax and flu exhibit strikingly similar symptoms-fever, chills and muscle aches-in the early days of the infection.Physicians would be quick to suspect anthrax in anyone who was vaccinated(接种疫苗)against flu and still developed fever and chills. That would give them a better chance to identify any new victims of terror while their infection was still in its earliest,most treatable stages.

    The World Health Organization(WHO)says as many as 10 million persons worldwide
    may have the virus that causes AIDS(艾滋病).Experts believe about 350, 000 persons
    have the disease.And one million more may get it in the next five years. In the United
    States,about 50,000 persons have died with AIDS.The country's top medical official
    says more than 90 percent of all Americans who had the AIDS virus five years ago are
    dead.
    There is no cure for AIDS and no vaccine(疫苗)or medicine to prevent it. However,
    researchers know much more about AIDS than they did」ust a few years ago.We now know
    that AIDS is caused by a virus.The virus invades healthy cells,including white blood cells
    that are part of our defense system against disease.It takes control of the healthy cell's
    genetic material and forces the cell to make a copy of the virus.The cell then dies.And the
    virus-caused particles move on to invade and kill more healthy cells.
    The AIDS virus is carried in a person's body fluids.The virus can be passed sexually or
    by sharing instruments used to take intravenous(进入静脉的)drugs. It also can be passed
    in blood products or from a pregnant woman with AIDS to her developing baby.
    Many stories about the spread of AIDS are false.You cannot get AIDS by working or
    attending school with someone who has the disease.You cannot get it by touching drinking
    glasses or other objects used by such persons.Experts say no one has gotten AIDS by

    Practice 1  Healthy people with stressful jobs who work long hours but get little satisfaction from what they do have twice the risk of dying from heart disease as satisfied employees, according to a study.  Job stress has been known to trigger heart problems in people who already have cardiovascular disease. Now Finnish scientists have now shown that even in healthy people the pressures of work can take their toll.  Obesity, high blood pressure, lack of exercise, smoking and being overweight contribute to heart disease — a leading killer in many industrialized countries.  But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the medical histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role.  Workers who had the highest job-related stress levels at the start of the study were more than twice as likely to die of heart disease, according to the study published in The British Medical Journal.  Work stress involves too much work as well as a lack of satisfaction and feeling undervalued and unappreciated.  Many people work long hours but if the effort is rewarding the stress is minimized. Kivimaki said job pressure is damaging when being overworked is combined with little or no control, unfair supervision and few career opportunities.  The British Heart Foundation said the results support earlier research showing that people in jobs with low control, such as manual workers, could be at greater risk of heart disease than other employees.  "It is advisable for people to try to minimize levels of stress at work and for employers to allow people to have more control at work and to be rewarded for their successes," the foundation said in a statement.

    研究表明:在健康人群中,那些工作时间很长但是却对工作现状不满的人死于心脏疾病的几率是正常人的两倍。
    众所周知,对于心血管功能不好的人来说,太大的工作压力更容易引起心血管疾病。但最近芬兰科学家的研究结果告诉我们,即便对于健康人来说,工作压力仍有可能夺去他们宝贵的生命。
    在许多发达的工业化国家,心脏病是夺走人们健康的头号杀手,而引起心脏病的因素有很多,包括肥胖、高血压、缺乏锻炼、抽烟甚至体重超重等等。
    然而,在过去的25年里,芬兰职业卫生研究所米卡·基维迈基和他的同事们对芬兰一家金属公司的812名健康芬兰职工进行了长期的病史跟踪研究。结论是:工作压力过大同样也是导致心脏病发作的重要因素之一。
    基维迈基将自己的研究结果发表在《英国医学杂志》上,文中他提到,他在研究初期发现,工作压力过大的人群死于心脏病的几率是正常人的两倍之多。
    工作压力包含很多方面,如工作量过大、对工作感到不满意、或在工作中不得志等。
    有时经常会出现这样一种情况:许多人工作量也相当大,但是工作很有成效,这种情况下工作压力就会相对减轻。基维迈基说工作量过大的人如果遇上差劲的管理、糟糕的上司和黯淡的工作前景,工作压力就会骤增,对健康的破坏力也同时加强。
    英国心脏基金会认为基维迈基的这一调查与基金会早前的一项研究结果一致。在那份研究中他们得出的结论是:在工作控制较低的行业工作的人,如体力劳动者,得心脏病的几率就明显高于其他行业。
    基金会的一份文件中这样写道:建议人们平时在工作当中要量力而行,尽量将工作压力降到最小程度。同时雇主们也要尽量减轻员工的工作压力,改善管理体系并及时论功行赏。

    Directions:In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in as few words as possible (not more than 10 words). Remember to write the answers on the Answer Sheet.  Questions 1-5 are based on the following passage.  Many people today are worried about bird flu. They are afraid that it will pass from birds to humans and that thousands of people will die in a pandemic. In 1918 a flu virus killed about 50 million people around the world. The virus was called Spanish influenza (or Spanish flu, for short) because Spanish newspapers first described the disease. Now, after nine years of work, scientists in an American laboratory in Atlanta, Georgia, have produced a copy of the Spanish flu virus. They are also going to publish the genetic sequence of the virus on the Internet and some experts are afraid that other laboratories could copy the virus.  Scientists have copied the virus because they want to understand why the 1918 Spanish flu pandemic killed so many people. In a report in the journal Science, Dr. Jeffery Taubenberger and a team of scientists in the USA show that the copied virus is extremely powerful. The scientists injected the virus into mice and the mice began to lose weight very quickly. They lost 13% of their weight in two days and all of the mice died within six days.  “I didn’t expect it to be as lethal as it was,”Dr. Terrence Tumpey, one of the scientists in the team, told the journal Nature. In another experiment, they injected more mice with a normal type of flu. The mice lost weight at first but then they got better and did not die. The experiments showed that the mice with the Spanish flu virus had 39,000 times more flu virus in their bodies than the second group of mice.  The scientists who copied the virus say their work has already provided important information about the virus and helps to explain why it is so lethal. But other experts are worried that the virus could escape from the laboratory. “Some people will think that they have really created a biological weapon,” said Professor Ronald Atlas of the University of Louisville in Kentucky. “I am even more worried now than I was before about the possibility of a flu pandemic. The 1918 flu pandemic started with bird flu and that might happen again today with Asian bird flu.”  Some scientists are worried about the publication of the genetic sequence on the Internet. They are afraid that biologists could copy the virus using the information on the Internet. This could be very dangerous.  It took a long time to copy the virus. Scientists used material taken from the lungs of people who died from the flu virus in 1918. In a second report in Nature, Taubenberger and his colleagues analyzed the genetic make-up of the virus. They were surprised to find that it was completely different from all the normal human flu viruses. This probably means that Spanish flu jumped from birds to humans and did not mix with a human virus first. This is very worrying for scientists because in the past everyone believed that a pandemic was only possible if a bird flu virus mixed with a human flu virus.  Taubenberger says it is very important to know what changes in the virus caused the 1918 Spanish flu virus. This will help scientists to work out which viruses might cause a pandemic. The H5N1 bird flu in Asia is already changing and it could infect humans, he said.  Viruses have escaped from high-security labs before. The SARS virus escaped at least twice, once in Taiwan and once in Singapore. But some scientists believe a pandemic will not happen even if the virus escapes, because most people are naturally immune and there are now a lot of drugs which protect people from flu.  Questions:  1.When was the Spanish flu pandemic?  2.How many people died in the Spanish flu pandemic?  3.Where did the scientists produce a copy of the Spanish flu virus?  4.How quickly did the laboratory mice die?  5.What is H5N1?

    正确答案:
    1.1918年 文章第一段提到In 1918 a flu virus killed about 50 million people around the world. The virus was called Spanish influenza.
    2.About 50 million. 文章第一段提到flu virus killed about 50 million people.
    3.Atlanta, Georgia, USA (in a laboratory). 文章第一段提到scientists in an American laboratory in Atlanta, Georgia, have produced a copy of the Spanish flu virus.
    4.Within 6 days. 文章第二段最后一句提到mice died within six days .

    Wild Birds Treated as Bird-flu Carriers  Avian influenza, also known as bird-flu, is dominating headlines in some parts of the world. The first cases of the deadly HSN1 swain of the virus have been confirmed in Europe and there have been new outbreaks in Asia. Bird-flu is here to stay, according to the World Health Organization, and countries are revising their procedures on how to prevent, or at the very least delay, a human pandemic. In areas where the virus has already been confirmed, like Romania, most efforts focus on trying to keep domestic birds away from wild local birds like swans, and migrating birds like geese. In the wetlands of the Danube delta thousands of hens, ducks and geese have already been slaughtered.  Some ornithologists plead that we’d better not demonize the wild birds. Bird flu began among poultry in south-east Asia, almost certainly because of the way people treat domestic birds, cramped together in small cages. They infected the wild birds, which are now bringing the virus to Europe and Africa. Poultry are catching it, and sooner or later, so will humans. It’s coming full circles. So don’t blame the birds. Blame human cruelty.  On a lake in Mined, not far from the delta capital Tulcea, two pigmy cormorants,10 domestic ducks, egrets, black-headed gulls, and swans, lots of swans. Sleeping. They shouldn’t be sleeping now. It’s the middle of the day! Perhaps they’re sick. Swans have borne the brunt of the bird-flu outbreak here so far. They were weak anyway, because of the floods which have struck Romania this Spring and Summer. Swans thrive in water not much deeper than one metre. They plunge their long necks under water to feed. With water levels unusually high, the swans have take refuge this year in fish farms, where many shallow, man-made pools offer rich pickings. But other birds, domestic and wild, gather there too-and such concentrations of birds, experts say, create a perfect environment for spreading disease. In the second confirmed bird-flu cluster in the delta,137 swans have died, on a fish farm in the village of Maliue. In the third cluster, near the Ukrainian border,15 swans have died so far.  The number may not be huge, but this is undoubtedly the tip of the avian influenza iceberg. Bird-flu is already present in Romania’s neighbors, Ukraine, Moldova, and Bulgaria. White-fronted geese can travel 500 kilometers in a single day! Scientists should concentrate on a vaccine to prevent the virus in birds, and not put all their efforts into the human version.  According to experts from the World Health Organization, the virus will remain for a long time in the region. More cases of bird-flu will be discovered, And each time, a major quarantine operation will have to be launched. To kill poultry, to closely observe those who have come into contact with sick birds, and seal off the area. People throughout this wetland region will just have to learn a new way of life. And so will their hens and ducks and geese.  Like the tale of the Sultan’s gold coin, no one can say how this story will end.

    野生鸟类被认为是禽流感的带苗者 禽流感,也就是鸟类的感冒,一直占据着世界上一些国家的头版头条。第一例由致命的H5N1型禽流感导致的病例已经在欧洲得到了证实,而亚洲又有新的疫病爆发。世界卫生组织认为禽流感将会困扰世界,而各国也正在改进他们的措施,以便能阻止或至少是延缓禽流感在人类流行。在一些已经被证实有禽流感的地区,比如罗马尼亚,人们竭尽全力让家禽远离当地野生的鸟类,例如天鹅;以及迁徒的鸟类,例如鹅。多瑙河三角洲的沼泽地带成千上万的鸡、鸭、鹅已经被屠杀。
    一些鸟类学家恳求道,我们最好不要把野生鸟类当成恶魔。禽流感最初是在东南亚的家禽中传播开来,几乎可以肯定的是禽流感产生的原因是人们把家禽关在一个很小的笼子里导致的。随后这些家禽开始传染野生鸟类,而野生鸟类把病毒带到了欧洲和非洲。禽流感正在家禽中蔓延,迟早人类也会被感染。这将成为一个循环。因此不应该责备鸟类,应该责备的是人类的残酷。
    在距三角洲首府图尔恰不远的弥勒日的湖上,两只矮鸬鹚,十只家鸭,白鹭,黑头鸥和很多天鹅昏昏沉睡。大中午的,它们现在还不到睡觉的时间!也许它们生病了。迄今为止,天鹅已经承受了禽流感所带来的冲击。不管怎样,在今年春天和夏天罗马尼亚的水灾中它们已经很虚弱了。天鹅在不到一米深的水中成长。它们把修长的脖子伸到水下觅食。由于今年水位异乎寻常地高,天鹅都到养鱼场避难,那里的人造水池很浅,给天鹅提供了充足的食料。但是其他的鸟类——家养或野生的也都聚在那里——专家认为,鸟类如此地聚集在一起给疾病的传播提供了理想的场所。在这个三角洲被确认的第二次禽流感的大规模爆发中,马留克村庄的一个养鱼场内死了137只天鹅。第三次的爆发发生在乌克兰边界附近,目前已有15只天鹅死亡。
    数目也许并不大,但这无疑是禽流感冰山的一角。禽流感已经光顾了罗马尼亚的邻国乌克兰、摩尔多瓦和保加利亚。白头鹅一日可飞行500公里!科学家应该集中精力研制出一种疫苗来预防鸟类总的病毒,而不是把他们所有的精力都投入到人类预防禽流感疫苗的研究中去。
    据世界卫生组织的专家说,这种病毒将在这一地区存留很长的时间。越来越多的禽流感的病例将会被发现。每一次都要进行大规模的检疫隔离行动。宰杀家禽,近距离地观察那些曾和生病的鸟类接触过的人,并把这个地区封锁起来。整个沼泽地区的人们都必须学会一种新的生活方式,而他们的鸡、鸭、鹅也必须学会这种方式。
    就像苏丹金币的故事一样,没人能够知道故事会怎样结束。

    Text 1 The influenza season is just getting started in the United States,and it already promises to be more severe than usual.Hospital emergency rooms are filling up with flu sufferers,and pharmacies have reported medicine shortages.Twelve children had died as of last month.To make matters worse,in Australia,which experienced its flu season four to six months ago,the current vaccine appeared to be only about 10 percent effective against tlus year's dominant strain.Yet as bad as this winter's epidemic is,it won't compare with the flu pandemic that is almost certainly on the horizon if we don't dedicate energy and resources to a universal vaccine.The 1918 Spanish flu epidemic killed 50 million t0 100 million around the globe.Given the century of medical progress since then,one might conclude that we are far better prepared today to deal with such a worldwide catastrophe.Unfortunately,the opposite is true.The world has about four times the number of inhabitants it did in 1918,including hundreds of millions of people,poultry and pigs living close together.This provides a potent biologic mixing bowl and natural influenza virus mutation factory.When a pandemic does strike,we'll be in trouble in part because American hospitals and pharruacies keep in stock no more than a few days supply of most lifesaving drugs,almost all of which are made in Asia.Worldwide manufacturing and shipping are highly susceptible to disruption,which could mean shortages in many areas.A 1918-type influenza pandemic could cause ruin on the order of what the Black Death did t0 14th-century Europe,but on a global scale.Our current vaccines are based on 1940s research.Limited global manufacturing capacity combined with the five to six months it takes to make these vaccines mean many people would never even have a chance to be vaccinated.Little is being done to aggressively change this unacceptable situation.We will have worldwide flu pandemics.Only their severity is unknown.The only real solution is a universal vaccine that effectively attacks all influenza A strains,with reliable protection lasting for years,like other modem vaccines.Although the National Institutes of Health has publicly declared developing a vaccine a priority,it has only about$32 million this year specifically for such research.The Biomedical Advanced Research and Development Authority,the other federal agency responsible for developing and making available new vaccines for emergency response,has in fiscal year 2017 0nly a single project for$43 million supporting game-changing infiuenza vaccines.By contrast,the search for an H.I,V.vaccine-still a scientific long shot-receives Sl billion annually.We estimate that intemational govemments,vaccine manufacturers and the philanthropic community must make a similar commitment to influenza vaccine research if the kind of vaccine we need is to developed in the next 10 years.But there is no apparent effort to make these vaccines a priority in the current administration 21.The urgent task on hand is to

    A.solve medicine shortage.
    B.develop a new vaccine.
    C.go into a universal vaccine.
    D.control the spread ofinfiuenza.

    答案:C
    解析:
    事实细节题。根据题干信息定位到第一段,第一段前几句论述了美国流感疫情的严重情形,最后一句提到,与今冬的流感一样糟糕的是,如果我们不集中精力和资源来研究出一种通用疫苗的话,现有的疫苗是无法与几乎近在眼前的流感大流行相抗衡的,所以研制通用疫苗是重中之重,故C项为正确选项。【干扰排除】A项、B项和D项并不是题目所问的当务之急,故排除。

    Text 3 In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association(NBA)listed at over seven feet.If he had played last season,however,he would have been one of 42.The bodies playing major professional sports have changed dramatically over the years,and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger,longer frames.The trend in sports,though,may be obscuring an unrecognized reality:Americans have generally stopped growing.Though typically about two inches taller now than 140 years ago,today’s people–especially those born to families who have lived in the U.S.for many generations–apparently reached their limit in the early 1960s.And they aren’t likely to get any taller.“In the general population today,at this genetic,environmental level,we’ve pretty much gone as far as we can go,”says anthropologist William Cameron Chumlea of Wright State University.In the case of NBA players,their increase in height appears to result from the increasingly common practice of recruiting players from all over the world.Growth,which rarely continues beyond the age of 20,demands calories and nutrients–notably,protein–to feed expanding tissues.At the start of the 20th century,under-nutrition and childhood infections got in the way.But as diet and health improved,children and adolescents have,on average,increased in height by about an inch and a half every 20 years,a pattern known as the secular trend in height.Yet according to the Centers for Disease Control and Prevention,average height–5′9″for men,5′4″for women–hasn’t really changed since 1960.Genetically speaking,there are advantages to avoiding substantial height.During childbirth,larger babies have more difficulty passing through the birth canal.Moreover,even though humans have been upright for millions of years,our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs.“There are some real constraints that are set by the genetic architecture of the individual organism,”says anthropologist William Leonard of Northwestern University.Genetic maximums can change,but don’t expect this to happen soon.ClaireC.Gordon,senior anthropologist at the Army Research Center in Natick,Mass.,ensures that 90 percent of the uniforms and workstations fit recruits without alteration.She says that,unlike those for basketball,the length of military uniforms has not changed for some time.And if you need to predict human height in the near future to design a piece of equipment,Gordon says that by and large,“you could use today’s data and feel fairly confident.”33.On which of the following statements would the author most probably agree?

    A.Non-Americans add to the average height of the nation.
    B.Human height is conditioned by the upright posture.
    C.Americans are the tallest on average in the world.
    D.Larger babies tend to become taller in adulthood.

    答案:B
    解析:
    有关作者可能同意的论述会涉及到整个篇章,因此无法定位到具体一段,则需要通过排除法依次对每项进行分析来解答。A项张冠李戴,文中第二段末句提到NBA球员身高的增长可能是从世界各国吸收球员的结果,由此我们只能推知非美国人对NBA球队的平均身高有影响,而选项中的美国替代了NBA球队,扩大概念。而且此项表述过于绝对,文中并没有定论,故排除;B项所在的段落应为第四段,第三句提到人类的两足和背部仍在同直立行走的姿势相抗衡,难以承受因肢体过长造成的压力,末句引用专家的话作总结指出,对身高的限制是由遗传结构决定的,因此B项

    Flu Shots Or Not?
    It sounded like a good idea when New York City's mayor,Rudollph Giuliani,advised New Yorkers recently to get a flu shot.After all,20,000 Americans each year die of influenza. And this year in particular,the mayor suggested,getting a flu shot might be an especially good idea, since it could help doctors distinguish between flu and the deadly inhalational(吸入的)form of anthrax(炭疽).How? Both anthrax and flu exhibit strikingly similar symptoms-fever, chills and muscle aches-in the early days of the infection.Physicians would be quick to suspect anthrax in anyone who was vaccinated(接种疫苗)against flu and still developed fever and chills. That would give them a better chance to identify any new victims of terror while their infection was still in its earliest,most treatable stages.
    Or so the mayor's reasoning went. Unfortunately,there are a couple of problems with his log-ic .For one thing,getting vaccinated against influenza doesn't guarantee you won't get sick .Al-though highly effective,the flu vaccine(疫苗)protects against only the dominant types of the dis-ease and even then does not provide 100% protection.It takes a couple of weeks for your body to respond to the vaccine with a sufficient number of antibodies(抗体).Each year thousands of
    Americans who get the vaccine nevertheless still get the flu.
    There are also plenty of reasons you might develop fever,chills and muscle aches that have nothing to do with either anthrax or flu .Indeed,doctors estimate that more than 80%of all flu-like illnesses each winter are caused by other groups of viruses.Getting vaccinated against flu can't protect you against suffering from these other illnesses.
    In the worst case,asking all healthy adults to get vaccinated could actually have the opposite effect to the one intended,leading to even more deaths if it means we run out of shots for those who are most vulnerable to the infection.Already there have been delays in getting this year's shipment of vaccine to clinics and doctor's offices.Those who should be at the front of the line in-clude folks who are 65 or older,nursing-home residents and adults and children with chronic health problems as well as anyone who cares for or lives with such people .Flu shots are also im- portant for men and women whose immune system is weakened by HIV(艾滋病病毒)or other conditions.
    The best reason to get the flu vaccine is that it proteets against most flus-not that you're worried about getting anthrax.While inhalational anthrax has killed only five people so far,many more could be at risk from flu-related complications.There's no need to worsen the tragedy by making this year's influenza epidemic any worse.

    People who care for those most vulnerable to the influenza infection needn't get flu shots.

    The Spanish Flu Epidemic
    If you're worried about the possibility of a coming bird flu epidemic,you can take
    comfort in the fact that humanity has survived a similar influenza epidemic in the past.
    Starting its rounds at the end of World War!,the 1918 flu killed an estimated 50 million
    people.
    Popularly known as the Spanish Flu,this type of influenza was far worse than your
    common cold.Normally,influenza only kills those who are more vulnerable to disease,
    such as newborns,the old or the sick.However,the Spanish Flu was prone to kill the
    young and healthy.Often it would disable its victims in hours;within a day,they would be
    dead,typically from extreme cases of pneumonia(肺炎).
    The Spanish Flu was quite nasty-fast-spreading and deadly. It managed to spread
    across the globe,devastating the world.Then suddenly,after two years ravaging(蹂躏)
    the Earth,it disappeared as quickly as it had arisen.
    Despite its nickname,the Spanish Flu did not originate in Spain.Its true origins are
    unknown.Some believe it started in US forts and then spread to Europe as America joined
    the war;others think that it populated the trenches of the English and the French and
    eventually broke out in 1918.Regardless of where it started,eventually a fifth of the world
    population suffered the disease,with a global mortality rate(死亡率)estimated at 2. 5% of
    the population.
    Modernity was partly to blame for the quick spread of the disease.It passed throughout
    the world on trade routes and shipping lines.It hit Northern America,Europe,Asia,Africa
    and the South Pacific.The war did not help at all一the movement of supplies and troops
    aided the spread of the Spanish Flu,as well as the trench warfare:!magine the speed at
    which a virus can spread in a crowded ditch.The fast emergence of the virus in the
    trenches caused some soldiers to believe that the Spanish Flu was a new form of biological
    warfare.
    Luckily,the Spanish Flu simply vanished by 1920.It is believed the flu simply ran out
    of fuel to spread.

    The Spanish Flu disappeared two years after it broke out.

  • 第21题:

    Questions 11 to 15 are based on the following passage. Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症),a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one. According to the passage, to combat the flu effectively, ()

    • A、one should identify the virus which causes it
    • B、one should consult a doctor as soon as possible
    • C、one should take medicine upon catching the disease
    • D、one should remain alert when the disease is spreading
