1、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。

2、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.Oral problems in children can develop into more severe problems.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，答案依据比较明显，带者题干信息词回文章定位，答案依据在文章第四段第二句：When these problems are not caught early and treated，they can develop into more severe problem and cause unnecessary suffering谈到这些问题如果没能及早发现和治疗，会发展成更严重的问题，所以本题和原文句意相符，答案是A。

3、Acceptance of Chronic IllnessFor chronically ill patients, giving up the hope that they will get better may actually lead to more happiness, U. S. researchers suggest."Hope is an important part of happiness, but there\'s a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness," Dr. Peter A. Ubel from the University of Michigan Health System said in a university news release.He and his colleagues studied patients who\'d just had a colostomy (结肠造口术), which means their colons (结肠) were removed and they had to have bowel (肠) movements in a pouch (小袋) outside the body. At the time of the surgery, some patients were told the procedure was reversible and they\'d have a second operation in a few months to reconnect their bowels. Other patients were told the colostomy was permanent.The patients were followed for six months, and the researchers found that those without hope of regaining normal bowel function were happier than those with reversible colostomies."We think they were happier because they got on with their life. They realized the cards they were dealt, and recognized that they had no choice but to play with those cards," Ubel said. "The other group was waiting for their colostomy to be reversed. They contrasted their current life with the life they hoped to lead, and didn\'t make the best of their current situation. "The study, published in the November edition of Health Psychology, also may explain why people whose spouse dies often recover better emotionally over time than those who get divorced, the researchers said.That\'s because people whose husband or wife dies have closure (结束), while those who get divorced may still have hope for some chance of making up, they explained.Chronically ill patients may be happier ______.【单选题】

A.if they keep thinking of their past

B.if they believe they\'ll recover

C.if they put off moving on

D.if they manage to get on with their life

正确答案:D

答案解析:本题有一定难度，关键在吃透原文句意和选项意思。答案依据在文章第一段，第一段谈到，对于慢性病病人来说，放下身体会变好的希望可能会使他们更幸福，回来看选项，D项和原文句意相符，是答案。考生要理解好D项里get on with这个短语，此处指“生活会过得好”。

4、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.The study included 204 married and 99 single adults who wore portable blood - pressure monitors for 24 hours. The monitors recorded blood pressure at random intervals and provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally ____ in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】

A.take

B.do

C.make

D.want

正确答案:B

答案解析:本题难度不大，考查词义辨析。文章此处是说“……不管测试者每天都做什么”，很明显，要用动词do，答案是B。

5、SemcoAt 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts for ships. Semler Junior worked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctor who treated him said, "There\'s nothing wrong with you. But if you continue like this, you\'ll find a new home in our hospital." Semler got the message. He changed the way he worked. In fact, he changed the way his employees worked too.He let his workers take more responsibility so that they would be the ones worrying when things went wrong. He allowed them to set their own salaries, and he cut all the jobs he thought were unnecessary, like receptionists and secretaries. This saved money and brought more equality to the company. "Everyone at Semco, even top managers, meets guests in reception, does the photocopying, sends faxes, types letters and dials the phone."He completely reorganized the office, instead of walls, they have plants at Semco, so bosses can\'t shut themselves away from everyone else. And the workers are free to decorate their workspace as they want. As for uniforms, some people wear suits and others wear T - shirts.Semler says, "We have a sales manager named Rubin Agater who sits there reading the newspaper hour after hour. He doesn\'t even pretend to be busy. But when a Semco pump an the other side of the world fails and millions of gallons of oil are about to spill into the sea, Rubin springs into action.He knows everything there is to know about our pumps and how to fix them. That\'s when he earns his salary. No one cares if he doesn\'t look busy the rest of the time."Semco has flexible working hours, the employees decide when they need to arrive at work, The employees also evaluate their bosses twice a year. ____It sounds perfect, but does it work? The answer is in the numbers. In the last six years, Semco\'s revenues have gone from $ 35 million to $ 212 million. The company has grown from eight hundred employees to 3,000, Why?Semler says it\'s because of "peer pressure". Peer pressure makes everyone work hard for everyone else. doing his job well, the other workers will not allow the situation to continue. In other words, Ricardo Semler treats his workers like adults and expects them to act like adults, And they do. 【单选题】

正确答案:A

答案解析:本题难度也较大，需要认真阅读文章，可用排除法和代入法。本题的上文谈到公司上班时间灵活，员工可自行决定上班时间，接着出现了also 一词，表明应该有并列内容的陈述，下文出现了It，是对这个福利制度的继续讨论。而且49题在同一段落，没有另起一段，可以推断本题会继续讨论与员工自由和福利有关的内容，回来看选项，把A代入文章里，符合上下文逻辑，是答案。
