1、When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction and find ways to combat it. Oftentimes, success is achieved, as medical science is able to isolate the parasite, germ or cell that causes the problem and finds ways to effectively kill or contain it. In the most serious of cases, in which the entire population of a region or country may be at grave risk, it is deemed necessary to protect the entire population through vaccination, so as to safeguard lives and ensure that the disease will not spread.The process of vaccination allows the patient\'s body to develop immunity to the virus or disease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak or dead strain of the disease is actually injected into the patient in a controlled environment, so that his body\'s immune system can learn to fight the invader properly. Information on how to penetrate the disease\'s defenses is transmitted to all elements of the patient\'s immune system in a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped and trained to deal with it, having already done so before.There are dangers inherent in the process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much for the body to handle, resulting in the immune system succumbing, and, therefore, the patient\'s death. Such is the case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and killed massive numbers of settlers. Approximately l in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3,000 Americans would be left dead.Fortunately, the smallpox virus was considered eradicated in the early 1970\'s, ending the mandatory vaccination of all babies in America. In the event of a re-introduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.The best title for the text may be____.【单选题】

A.“Vaccinations: A Blessing or A Curse”

B.“Principles of Vaccinations”

C.“Vaccines: Methods and Implications”

D.“A Miracle Cure Under Attack”

正确答案:C

答案解析:主旨题。选项C“疫苗：方法和内在含义”充分地概括说明了文章的主旨大意；而选项A、B、D均只涉及原文中的部分内容，以偏赅全，不能包含文章的全部内容。故正确答案为C。

2、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed or sofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be upset when their parents left, and so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professor of nursing at the University of Salford, said that the work of ____ like Pamela had changed the face of patient care."Pamela\'s study was done against the background of a lively debate in paediatrics and psychology as to the degree women should spend with children in the outside world and the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to visita small child in hospital the child would be upset and inconsolable (无法安慰的) for hours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope that mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone and depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive and general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handed their children over to strangers at the door of the hospital ward.""As a result of her work, parents are now recognized as partners in care and are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' and children\'s experience of care." 【单选题】

A.parents

B.nurses

C.doctors

D.teachers

正确答案:B

答案解析:本题难度不大，考查词义辨析，干扰项干扰不大，可以先看选项得到信息提示。文章第四段第一句：A concerned nurse，Pamela Hawthorn - -是信息提示，表明Pamela是护士，nurse，答案是B。

3、Parkinson\'s Disease1. Parkinson\'s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine(多巴胺). Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson\'s, these nerve cells break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to.2. No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson\'s disease in some people. But so far, there is not enough proof to show that it is always inherited.3. Tremor (颤抖) may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. Tremor often starts in just one arm or leg or only on one side of the body. It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or you are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing or constipation(便秘) . In the later stages of the disease, a person with Parkinson\'s may have a fixed or blank expression, trouble speaking, and other problems. Some people also have a decrease in mental skills.4. At this time, there is no cure for Parkinson\'s disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You may not even need treatment if your symptoms are not obvious. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.You\'ll find it hard to move the way you want to ______.【单选题】

A.if there isn’t enough dopamine in your body

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed or blank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:A

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第一段最后一句，Then you no longer have enough dopamine, and you have trouble moving the way you want to.谈到如果你没有足够多的多巴胺，行动就会变得困难，答案是A。

4、Blasts from the Past 1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease. 2 Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300. million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do. 3 Wignall calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals. 4 The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in. Siberia that cover an area roughly the size of western Europe, Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide, The global warming that followed wiped out 8 per cent of all marine genera at the time, and it took 5 million years far tire planet to recover. 5 Yet 60 million years ago in the late Palaeocene there was another huge amount of volcanic activity and global-warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years, "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. 6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up and exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere. 7 Vincent Courtillot, director of the Paris Geophysical Institute in France, says that Wignall\'s idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they fasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years. 8 Courtillot also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide or sulphur dioxide emissions. Paragraph 5____ 【单选题】

A.Killing Power of Ancient Volcanic Eruptions

B.Association of Mass Extinction with Volcanic Eruption

C.Calculation of the Killing Power of Older Eruptions

D.A Mass Extinction

E.Volcanic Eruptions That Caused No Mass Extinction

F.ccounting for the Killing Power of Older Eruptions

正确答案:E

答案解析:Volcanic eruptions that caused no mass extinction：没有造成大量生物灭绝的火山爆发。上面讲到了“较早的火山喷发在灭绝生物方面的效率至少是后来的火山喷发的10倍”。第五段就是对“后来的火山喷发”的灭绝生物能力不行的证明。

5、The Ideal HusbandScience now might be able to explain women\'s fascination with Brad Pitt\'s face and George Clooney\'s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.In the study by Daniel Kruger at the US\'s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something longer.The study was published in the December issue of the US journal Personal Relationships.Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible ____ the development of masculine facial features and other sexual characteristics. It has been found to affect the body\'s ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.However, increased testosterone has also been linked to cheating and violence in relationships. So, these men might produce high quality offspring, but they don\'t always make great parents or faithful mates, Kruger says.The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.【单选题】

A.of

B.at

C.for

D.in

正确答案:C

答案解析:这四个都是介词。responsible后面跟for。

6、Importance of Children\'s Oral HealthFebruary is National Children\'s Dental(牙齿的) Health Month, but in children good oral(口部的) care is critical every day. The first comprehensive study on the nation\'s oral health, released recently by the Office of the U. S. Surgeon General, calls dental and oral diseases a "silent epidemic (流行病)", even in children. The report states that more than 51 million school hours are lost each year to dental - related illness. In fact, a recent study pointed to dental care as the most common unmet health need among American children.To help counter this, the American Academy of Periodontology (牙周病学) (AAP) is launching an effort to educate children and parents about the prevention of dental diseases in children."This is important because oral problems can impact self - esteem for children and lead to problems of eating, speaking and attending to learning," said Michael McGuire, president of the AAP.Common dental problems seen in children are cavities (龋洞) and gingivitis (龈炎), which are found in the majority of U. S. children. "When these problems are not caught early and treated, they can develop into more severe problems and cause unnecessary suffering," said McGuire. "However, much of the time, oral problems are avoidable problems."In the Rio Grande Valley in Texas, a group of more than 120 dentists(牙医) volunteers to deliver dental care to thousands of low - income children each year with its Mobile Dental Unit that travels from school to school."According to the Surgeon General\'s Report, about 37 percent of children have not had a dental visit before starting school," said McGuire. When children don\'t see dentists, they miss the opportunity to have problems caught early before they develop into larger, more expensive problems to treat, and parents miss the opportunity to learn how to promote good oral habits in their children.Only in February should attention be paid to children\'s oral health.【单选题】

A.Right

B.Wrong

C.Not mentioned

7、ExerciseWhether or not exercise adds ____ the length of life, it is common experience that a certain amount of regular exercise improves the health and contributes a feeling of well-being. Furthermore, exercise which involves play and recreation, and relieves nervous tension and mental fatigue in so doing, is not only pleasant but beneficial.How much and what kind of exercise one should take merits careful consideration. The growing child and the normal young man and young woman thrill with the exhilaration of strenuous sports. They fatigue to the point of exhaustion but recover promptly with a period of rest. But not so with those of middle age and beyond. For them moderation is of vital importance. Just how much exercise a person of a given age can safely take is a question hard to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe for one person of forty but folly for another. The safe limit for exercise depends on the condition of the heart, the condition of the muscles, the type of exercise, and the regularity with which it is taken. Two general suggestions, however, will serve as sound advice for anyone. The first is that the condition of the heart and general health should be determined periodically by careful, thorough physical examinations. The other is that exercise should be kept below the point of physical exhaustion.What type of exercise one should choose depends upon one\'s physical condition. Young people can safely enjoy vigorous competitive sports, but most older persons do bet ter to limit themselves to less strenuous activities. Walking, swimming, skating are among the sports that one can enjoy and safely participate in throughout life. Regularity is important if one is to get the most enjoyment and benefit out of exercise.【单选题】

8、GypsiesWhen school was out, I hurried to find my sister and get out of the schoolyard before seeing anybody in my class. But Barbara and her friends had beaten us to the playground entrance and they seemed to be waiting for us. Barbara said, "So now you\'re in the A class. " She sounded impressed. "What\'s the A class?" I asked. Everybody made superior yet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, dopey? Didn\'t you know you were in the C class before, way in the back of the room?" Of course I hadn\'t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, and the idea of subdivisions within a grade had never occurred to me. The subdividing for the first marking period had been done before I came to the school, and 1 had never, in the six weeks I\'d been there, talked to anyone long enough to find out about the A, B, and C classes.I still could not understand why that had made such a difference to Barbara and her friends. I didn\'t yet know that it was shameful and dirty to be a transient laborer and ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house.I didn\'t know that we were gypsies, really (how that thought would have excited me then!), and that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn\'t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here and there like mists or winds. I didn\'t know that I was the only child who had camped on the Baumann\'s land ever to get out of the C class. I didn\'t know that school administrators and civic leaders held conferences to talk about the problem of transient laborers.I only knew that for two happy days I walked to school with Barbara and her friends, played hopscotch and jumped rope with them at class intervals, and was even invited into the house for some ginger ale ---- a strange drink I had never tasted before.Which of the following is not characteristic of Gypsies?【单选题】

A.Wandering around the world

B.Make ginger ale in their house.

C.Never plant something.

D.Had been foreigners wherever they go.

正确答案:C

答案解析:吉普赛人住帐篷，没什么房子，因而也不会在房子里做ginger ale。另外三项都是他们的生活特色。

9、Human Heart Can Make New CellsSolving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac(心脏的 ) cells throughout the life span, although the rate of new cell production slows with age.The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say."We find that the beating cells in the heart, cardiomyocytes (心肌细胞), are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.The process of renewing these cells changes over time, Frisen added. In a 20 - year - old, about I percent of cardiomyocytes are exchanged each year, but the turnover (更替) rate decreases with age to only 0.45 percent by age 75."If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals (药物) that promote this process to stimulate regeneration after, for example, a heart attack," Frisen said.That could lead to treatment that helps restore damaged hearts."A lot of people suffer from chronic heart failure," noted co - author Dr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.With this finding, scientists are "opening the door to potential therapies (疗法) to having ourselves heal ourselves." Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.It is not known yet if the rate of cell turnover in diseased hearts ______.【单选题】

A.is high enough to replace cells faster than they\'re dying off

B.is of any use to researchers

C.is the same as that in healthy hearts

D.changes over time

正确答案:C

答案解析:本题难度不大，答案依据比较明显。带着题干信息词回文章定位，答案依据是文章最后一段最后一句，谈到心脏新细胞的制造数量是按照健康心脏来计算的，但是患病心脏的细胞更新率是否一样还是未知，回来看选项，C项和原文句意相符，是答案。

10、Reduce PackagingPressure increased recently on British supermarkets and retailers to reduce packaging as part of an anti - waste campaign. The campaign was initiated by The Independent newspaper. Britain generates 4.6 million tons of household waste every year by packaging.Dozens of people have expressed anger at the excess of plastic wrapping. Campaigners have called on Britain to learn from other European countries, ____ When returned bottles are put in a vending machine 自动售货机, the deposit is refunded. Environmentalists warn that Britain lags behind in this.There were reports of growing unease among consumers over the amount of packaging they have to deal with. Trade standards officers also object to excessive packaging. This is because too much padding can give buyers a false impression of what they are buying.In response to a campaign by Britain\'s The Independent newspaper, leading supermarkets have pointed to various initiatives to win the public confidence. tons of cardboard a year by switching to reusable plastic crates 装货箱 for transporting its fresh produce.But campaigners said retailers and the government could learn much from anti - waste practices on the Continent. In Sweden, non - recyclable batteries have been taxed since 1991 to encourage a switch to alternatives. This has resulted in a 74 percent reduction in sales. In Germany, plastic bags are unheard of in supermarkets and deposits are paid for reusable plastic and glass beverage bottles.【单选题】

A.If a product is over packaged, don\'t buy it.

B.In Belgium, when you buy something in a plastic or glass container, you make a deposit.

C.This is because too much padding can give buyers a false impression of what they are buying.

D.This has resulted in a 74 percent reduction in sales.

E.Tesco said it was saving 112,000 tons of cardboard a year by switching to reusable plastic crates (装货箱) for transporting its fresh produce.

F.The campaign was initiated by The Independent newspaper.

正确答案:B
