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 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。

3、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto ａｎｄ　the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects ｏｒto improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French ａｎｄ　English participants, urban ａｎｄ　rural schools, ａｎｄ　schools located in high, moderate ａｎｄ　low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood ｏｒphysical ____; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep ｏｒstaying asleep; felt unhappy, sad, ｏｒdepressed; felt hopeless about the future; felt vexed, antsy ｏｒtense; ａｎｄ　worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professｏｒat the University of Montreal Department of Social ａｎｄ　Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression ａｎｄ　smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】

A.world

B.activity

C.state

D.beauty

正确答案:C

答案解析:科学家将参与者分成三组，其中一组的参与者不采用吸烟作为自我调节情绪的手段。填入的词应与情绪、身体等有关。若选A、B、D，组成的词组physical world（物质世界）、physical activity（体育活动）、physical beauty（形态美）均与上文的意思接不上，所以A、B、D不会是答案。由C的state组成的词组physical state（身体状况）与上文的意思连贯，因此C是答案。

4、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 fｏｒchildren 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, aｇｒｏｕｐof 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.The low - income children are very grateful to the dentists.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有一定难度，需要通读全文，吃透原文句意。主要答案依据在文章第五段：…aｇｒｏｕｐof more than 120 dentists volunteers to deliver dental care to thousands of low - income children each year，谈到志愿者每年给几千个低收入家庭的孩子治疗牙病，但没有提到孩子感激志愿者的问题，因此本题未提及，答案是C。

5、Musical Training Can Improve Communication Skills American scientists say musical training seems to improve communication skills ａｎｄ　language retardation. They found that developing musical skills involves the same process in the brain as learning how to speak. The scientists believe that could help children with learning disabilities. Nina Kraus is a neurobiologist at Northwestern University in Illinois. She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument ａｎｄ　watching other musicians. This process is not much different from learning how to speak. Both involve different senses. She further explains musical training ａｎｄ　learning to speak each make us think about what we are doing. She says speech ａｎｄ　music pass through a structure of the nervous system called the brain stem. The brain stem controls our ability to hear. Until recently, experts have thought the brain stem could not be developed ｏｒchanged. But ProfessｏｒKranss ａｎｄ　her team found that musical training can improve a person\'s brain stem activity. The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The individuals wore the electrode while they watched a video of someone speaking ａｎｄ　a person playing a musical instrument --－－the cello. ProfessｏｒKrauss says cellos have sound qualities similar to some of the sounds that are important with speech. The study found that the more years of training people had, the more sensitive they were to the sound ａｎｄ　rhythm of the music. Those who were involved in musical activities were the same people in whom the improvement of sensory events was the strongest. ____ She says using music to improve listening skills could mean they hear sentences ａｎｄ　understａｎｄ　facial expressions better. 【单选题】

A.Both involve different senses.

B.Nina Kraus is a neurobiologist at Northwestern University in Illinois.

C.Some disabled children attended the musical training Class.

D.It shows the importance of musical training to children with learning disabilities.

E.ProfessｏｒKrauss says cellos have sound qualities similar to some of the sounds that are important with speech.

F.The brain stem controls our ability to hear.

正确答案:D

答案解析:最后一段介绍音乐训练的方法和结果，以及对学习的关联和影响。选项D表达的意思是音乐训练的结果和对学习上有障碍的儿童所产生的正面影响，意思与其前后两句的意思完全配合，D是答案。

6、Flu doesScratchy throats, stuffy noses ａｎｄ　body aches all spell misery, but being able to tell if the cause is a cold ｏｒflu 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 fｏｒthe flu need to be taken soon after the illness sets in. As fｏｒcolds, 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 fｏｒeither illness, but the flu can be prevented by the flu vaccine (疫苗), which is, fｏｒmost 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 fｏｒall 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 doctｏｒif 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 ｏｒflu should not take aspirin fｏｒpain 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 fｏｒthe common cold but frequent hａｎｄ　washing ａｎｄ　avoiding close contact with people who have colds can reduce the likelihood of catching one.If children have flu-like symptoms, their parents ____.【单选题】

A.are advised not to give them aspirin

B.should watch out fｏｒsigns of Reye syndrome

C.are encouraged to take them to hospital fｏｒvaccination

D.should prevent them from mixing with people running a fever

正确答案:A

答案解析:第七段第二句直接指明了：儿童和十多岁的孩子不能服用阿司匹林来缓解伤风流感带来的疼痛，因为这有可能导致Reye综合症，会使肝脏和中枢神经系统处于少见的严重状态。

7、CancerCancer is aｇｒｏｕｐof many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally cells grow ａｎｄ　divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, ａｎｄ　old cells do not die when they should. The extra cells form a mass of tissue called a growth ｏｒtumor. Benign (良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal ａｎｄ　divide without control ｏｒorder.Scientists have learned that cancer is caused by changes in genes that normally control the growth ａｎｄ　death of cells. Certain lifestyle ａｎｄ　environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet radiation from the sun, ｏｒexposure to carcinogens (致癌物) in the workplace ｏｒin the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, ａｎｄ　biological therapy. The doctｏｒmay use one method ｏｒa combination of methods, depending on the type ａｎｄ　location of the cancer, whether the disease has spread, the patient\'s age ａｎｄ　general health, ａｎｄ　other factors. Because treatment fｏｒcancer can also damage healthy cells ａｎｄ　tissues, it often causes side effects. Patients ａｎｄ　doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells ａｎｄ　the risks of possible side effects.Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, ａｎｄ　the patient\'s tolerance fｏｒpain. Most pain occurs when the cancer grows ａｎｄ　presses against bones, organs, ｏｒnerves. Pain may also be a side effect of treatment. However, pain can generally be relieved ｏｒreduced with prescription medicines ｏｒover-the-counter drugs recommended by the doctor.Paragraph 4____.【单选题】

A.Does cancer always cause pain

B.Can cancer be prevented

C.What is cancer

D.How common is cancer

E.What causes cancer

F.How is cancer treated

正确答案:A

答案解析:第四段主题句为第一句，其意思是：患有癌症并不意味着总会疼痛。由此推断，该段回答了A选项“Does cancer always cause pain?”所提问题，故A为正确答案。

8、Smart Window Windows not only let light in to cut down an electricity use fｏｒlighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark ａｎｄ　anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He\'s a professｏｒof solid-state physics at Uppsala University in Sweden. "It\'s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows ａｎｄ　natural light are important fｏｒimproving the way people feel when they\'re stuck indoors. Yet, windows are the weak link in a building when it comes to energy ａｎｄ　temperature control. In the winter, cold air leaks in. When it\'s hot ａｎｄ　sunny, sunlight streams in. All of this sunlight carries lots of heat ａｎｄ　energy. ａｎｄ　all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a majｏｒfocus of energy research fｏｒa long time. Over the years, scientists have come up with a variety of strategies fｏｒcoating, glazing, ａｎｄ　layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. Electrochromic windows use electricity to change color. Fｏｒexample, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied ａｎｄ　dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it\'s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear ｏｒdark. One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. To make electrochromic windows change color, what is applied to the window glass? 【单选题】

A. Electricity.

B.Tungsten oxide.

C.A battery.

D.A voltage.

正确答案:B

答案解析:第五段第二句提供了答案。a sheet of glass coated with thin layers of chemical compound such as tungsten oxide中的coated是“涂上一层薄薄的……”的意思。

9、ExerciseWhether ｏｒnot exercise adds to 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. Fｏｒthem moderation is of vital importance. Just how much exercise a person of a given age can safely take is a question ____ to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe fｏｒone person of forty but folly fｏｒanother. The safe ｌｉｍｉｔfｏｒexercise 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 fｏｒanyone. 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 ｌｉｍｉｔthemselves 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】

A.easy

B.hard

C.impossible

D.unnecessary

正确答案:B

答案解析:从语法上分析，这个空格需要填上一个形容词作question的定语。从上下文分析，只能是hard比较合适，因为这里的hard＝difficult。

10、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. ____ 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. Also, Semco lets its workers use the company\'s machines fｏｒtheir own projects, ａｎｄ　makes them take holidays fｏｒat least thirty days 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:D

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。本题的上文谈到了新老板重新布置了办公室，下文转到谈论工作制服，可以推断，本题会接着办公室工作环境谈，回来找选项，D谈到了员工办公室，把D代入原文中，符合上下文逻辑，是答案。
