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 fｏｒthe 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 professｏｒof 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 ｏｒif 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, fｏｒexample, 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 - authｏｒDr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.With this finding, scientists are "opening the doｏｒto 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.In people in their mid -70s, only 0. 45 percent of cardiomyocytes ______.【单选题】

A.are still functional

B.are reduced each year

C.are replaced each year

D.are damaged each year

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，答案依据是文章第四段第二句，谈到到了75岁，心肌细胞的更新率就降到每年0. 45%，换句话说，到75岁时．每年只有0. 45%的心肌细胞被更新，回来看选项，C项和原文句意相符，是答案。

2、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let ____ of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.to?go

B.going

C.go

D.went

正确答案:C

答案解析:let后接动词原形，go符合这一原则。故C为正确答案。

3、SemcoAt 21, Ricardo Semler became boss of his father-s business in Brazil, Semco, which sold parts fｏｒships. Semler Juniｏｒworked like a madman, from 7:30 am. , until midnight every day. One afternoon, while touring a factory in New York, he collapsed. The doctｏｒwho 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 ｓｅｔtheir 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 fｏｒuniforms, 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 fｏｒeveryone 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】

A.Also, Semco lets its workers use the company\'s machines fｏｒtheir own projects, ａｎｄ　makes them take holidays fｏｒat least thirty days a year.

B.Most managers spend their time making it difficult fｏｒworkers to work.

C.This saved money ａｎｄ　brought more equality to the company.

D.ａｎｄ　the workers are free to decorate their workspace as they want.

E.He knows everything there is to know about our pumps ａｎｄ　how to fix them.

F.If someone isn\'t doing his job well, the other workers will not allow the situation to continue.

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。

5、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 ｏｒso far on the ward.But until the 1970s this practice was not only frowned upon, it was actively discouraged. Staff worried that the children were upｓｅｔwhen their parents left, ａｎｄ　so there was a blanket ban.A concerned nurse, Pamela Hawthorn, disagreed ａｎｄ　her study "Nurse! I want my mummy" published in 1974 , changed the face of paediatric nursing.Martin Johnson, a professｏｒof nursing at the University of Salford, said that the work of nurses 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 visit a small child in hospital the child would be upｓｅｔａｎｄ　inconsolable fｏｒhours. ""Yet the nurse noticed that if mum did not come at ____ 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 eve 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. ""Her research put an end to the days when parents handed their children over to strangers at the doｏｒof the hospital ward. ""As a result of her work, parents ａｎｄ　careers are now recognized as partners ａｎｄ　are afforded the opportunity to stay with their children whilst they are in hospital, which has dramatically improved both parents\' ａｎｄ　children\'s experience of care.
