1、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac 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, 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 1 percent of cardiomyocytes are exchanged each year, but the turnover 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 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. 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 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.s 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:最后一句说：心脏产生的新细胞的数量是按照健康心脏计算的，而有心脏病的细胞更替率是否与健康心脏相同还不得而知。

2、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.The human heart stops producing cardiac cells ______.【单选题】

A.when a person becomes old

B.as soon as a person gets sick

C.immediately after a person is born

D.once a person dies

正确答案:D

答案解析:本题有一定难度，需要吃透原文句意，答案依据是文章第一段，谈到科学家发现人一生中心脏都会不停地制造新的心肌细胞，尽管新细胞产生的速度随年龄增长而放慢，换句话说，只有人死了，心脏才会停止制造心肌细胞，回来看选项，D项和原文句意相符，是答案。

3、Early childhood educationIn a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find in most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents.In the recent comparison of Japanese and American preschool education, 91 percent of Japanese respondents chose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented (强调个性发展的) Americans listed group experience as one of their top three choices. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education.Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children\'s chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.Free play has been introduced in some Japanese kindergartens in order to ____.【单选题】

A.broaden children\'s horizon

B.cultivate children\'s creativity

C.lighten children\'s study load

D.enrich children\'s knowledge

正确答案:C

答案解析:此题可以从全文的最后一句话得出答案。其他三个选项“扩大孩子的视野”、“培养孩子的创造力”和“丰富孩子的知识”文中无明确的说明。

4、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.The other group was not as happy because ______.【单选题】

A.they accepted their current situation

B.they were anxious to get better

C.they missed their previous life

D.they refused to play cards

正确答案:B

答案解析:本题有一定难度，需要吃透原文句意。答案依据比较明显，在文章第五段最后一句．谈到，不开心的第一组病人总是把现在的生活和他们想要的生活进行比较，没有很好地适应现在的生活。换句话说，他们很渴望早日恢复。回来看选项，B项和原文句意相符，是答案。

5、Youth Emancipation in SpainThe Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.Around 55 percent of people aged 18 ～ 34 in Spain still sleep in their parents\' home, says the latest report from the country\'s state - run Institute of Youth.To coax (劝诱) young people from their homes, the Institute started a "Youth Emancipation(解放)" programme this month. The programme offers guidance in finding rooms and jobs.Economists blame young people\'s family dependence on the precarious (不稳定的) labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000.Cultural reasons also contribute to the problem, say sociologists (社会学家). Family ties in south Europe (Italy, Portugal and Greece) are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Key for Understanding"."In general, young people in Spain firmly believe in the family as the main body around which their private life is organized," said Minguez.In Spain, especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews (外甥／侄子) all living on the same street. They regularly get together for Sunday dinner.Parents tolerance is another factor. Spanish parents accept late - night partying and are wary of setting bedtime rules."A child can arrive home at whatever time he wants. If parents complain he\'ll put up a fight and call the father a fascist," said Jose Antonio Gomez Yanez, a sociologist at Carlos Ill University in Madrid.Mothers willingness to do children\'s household chores (家务) worsens the problem. Dionisio Masso, a 60 - year - old in Madrid, has three children in their 20s, The eldest 28, has a girlfriend and a job. But life with mum is good."His mum does the wash and cooks for him, in the end, he lives well," Masso said.It can be inferred from paragraph 5 that family ties are stronger in Portugal than in ______.【单选题】

A.Greece

B.Finland

C.Spain

D.Italy

正确答案:B

答案解析:本题难度不大，是送分题。第五段第二句谈到了欧洲南部国家的家庭联系比欧洲中部和北部的国家更紧密，结合地理知识，芬兰位于北部，所以答案是B，此外，即使不靠地理知识，也可使用排除法做对这道题目，作者列举了三个国家都是在欧洲南部，选项A，C，D都是作者提到的，可以明显被排除掉，答案只能是B。
