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、Cooking Oil Fumes Cause TumorThe leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking, said medical experts after a fiveyear research study.Doctors announced the results yesterday with analysis on some new tendencies in lung cancer, They said patients are younger, especially women.According to the Shanghai Tumｏｒresearch Institute, more local residents die of lung cancer in the city than anything else. Following breast cancer, it has the second-highest incidence rate."An unhealthy lifestyle is a very important reason fｏｒlung cancer," said Dr He Yumin from Shanghai Minshen Traditional Chinese Medicine TumｏｒDiagnosis ａｎｄ　Treatment Center.He followed 2,276 lung cancer patients fｏｒfive years. Among them, 1,433 were male.Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking ｏｒinhaling second-hａｎｄ　smoke, according to the report.However, more than 60 percent of women with the disease had long term, close contact with strong oil fumes from cooking ａｎｄ　complained about irritated eyes ａｎｄ　throat.About 32 percent of women fried foods in boiling oil in unventilated kitchens ａｎｄ　about 25 percent of women\'s bedrooms were adjacent to the kitchen.However, local women were surprised to learn cooking oil fumes could lead to cancer. Some claimed they may change food preparation methods. "Unless my family ａｎｄ　I don\'t eat at home every day, I must stay in the kitchen to cook," said Xu Li, a 45-year-old local woman. "I know the fumes are bad fｏｒthe skin, but it is the first time I heard that it can result in lung cancer. I have already started frying less. "Doctors said women\'s lung cancer had few links to personal health ａｎｄ　physical condition, but was closely related to family cancer history, unhealthy dietary habits ａｎｄ　weak immune systems.Other experts agreed with him."Smoking is by far the biggest cause of lung cancer fｏｒmen," said Dr. Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University\'s Medical College. "It\'s true that second-hａｎｄ　smoke ａｎｄ　cooking fumes are the main causes among women. "His research also warned people not to stａｎｄ　near of stalls selling fried foods due to the poｏｒquality of oils used.The chance of catching lung cancer is three times higher if exposed to the fume fｏｒa long time, experts said.Which of the following has relatively little connection with women\'s lung cancer?【单选题】

A.Family cancer history.

B.Unhealthy dietary habits.

C.Weak immune systems.

D.Personal health ａｎｄ　physical condition.

正确答案:D

答案解析:细节考查题。回答此题时，应注意到文中“had few links to…”同“was closely related to…”这两处文字，link to同relate to都是联系的意思，但修饰它们的词few和closely差别很大，few表示否定意义，故正确答案为D。

3、Surprised by a MiracleI had been working in the trauma unit at a local hospital fｏｒabout a year. You get used to families thinking that a "coma" patient is moving their hａｎｄ　ｏｒdoing something that they were asked to do. "Following commands" is what we call it. Often it\'s "wishful thinking" on the Families\' part. Nurses can easily become callous to it.On this particular night during visiting hours, my patient\'s wife came in. I had taken care of him fｏｒseveral nights. I was very familiar with his care ａｎｄ　what he was able to do. Actually, he didn\'t do anything. He barely moved at all, even when something would obviously hurt him, such as suctioning.His wife was very short, about 5 feet tall. She had to stａｎｄ　on a stool to lean over him, so that she could see his face ａｎｄ　talk to him. She climbed up on the stool. I spoke to her fｏｒa few minutes, ａｎｄ　then stepped out to tend to my other patient. A few minutes later, she came running out of the room. In an excited voice, she said, "Donna, he\'s moving his hand!"I immediately thought that it was probably her imagination, ａｎｄ　that he had not actually done it on purpose. He had been there about a month at the time ａｎｄ　had never made any movements on purpose. I asked her what had happened ａｎｄ　she said, "I asked him to squeeze my hａｎｄ　ａｎｄ　he did!"This led me to another train of questioning. "But, did he let go when you asked him to?" She said yes, that he had done exactly what she asked.I went into the room with her, not really believing that I would see anything different than I had always seen. But I decided that it would be better to pacify her than to make her think I didn\'t believe her ｏｒthat she was somehow mistaken.She asked him to squeeze her hand, which he did. I said, "Well, ask him to let go. " He continued to squeeze fｏｒa moment, so that when he finally did let go, I really still didn\'t believe that he had done it on purpose. So, I said, "Ask him to hold up one finger. " He did as asked.Well, hmm, this was starting to get my attention. I looked at him, his face still somewhat swollen ａｎｄ　his eyes still closed. "Stick out your tongue!" I said. He did it. I almost fell on the floor. It was the first time I had ever seen anyone "wake up. "The first paragraph indicates that more often than not a coma patient ____.【单选题】

A.is found to be following commands

B.is thought to be following commands

C.is used to following commands

D.is callous to nurses\' commands

正确答案:B

答案解析:从短文的第一段可以得知，昏迷病人的家属时常以为病人能动了，但大多数情况下，这只是他们的愿望思维，病人并没有真正有意识地在动。

4、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. When are windows the weak link in a building? 【单选题】

A. In the cold winter.

B.In the hot summer.

C.When air conditioners are turned on.

D.Both A ａｎｄ　B.

正确答案:D

答案解析:短文第三段的第一句说：windows are the weak link in a building，接下来是对这句话分寒冬和炎夏做了说明，所以D是正确选择。

5、Online Cancer Chat with a Safety NetCancer Research UK has launched an online chat forum fｏｒcancer patients to swap (变换) stories ａｎｄ　share experiences on how to cope with such a devastating disease.But Cancer Chat is a forum with a difference: it has an information safety net.This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" ｏｒscientifically unsound information.Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.ａｎｄ　Rebekah Gibbs, cancer patient ａｎｄ　star of TWs Casualty, has pledged her support fｏｒthe new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer ａｎｄ　I have had such a heart - warming response from other people going through the same thing."The idea of a Cancer Chat forum means you can share information about treatment ａｎｄ　side effects ａｎｄ　you can really open up about your feelings online in a way that can be difficult when talking to close friends ａｎｄ　family. ａｎｄ　with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients ａｎｄ　their families 6,000 pages of up - to - date information that is easy to understａｎｄ　ａｎｄ　explains a wide range of treatments fｏｒdifferent types of cancer ａｎｄ　gives details of clinical trials. There is also a UK ｄａｔａｂａｓｅ of cancer clinical trials.The award - winning website attracts around one million visitors a month ａｎｄ　Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.Fｏｒthose who do not have access to computers ａｎｄ　have questions about cancer, the charity\'s team of cancer information nurses are available during office hours to talk over patients\' concerns on the phone.Which statement about the CancerHelp UK website is NOT true?【单选题】

A.It offers lots of information on cancer treatment ａｎｄ　clinical trials.

B.It attracts numerous visitors.

C.It has won an award.

D.It is accessible only to British citizens.

正确答案:D

答案解析:本题有一定难度，需要认真吃透原文句意，找出判断依据。认真阅读文章可以发现，选项里A，B，C三项在文中都提到了，第四段第一句，谈到任何人都可以上该论坛的网站浏览消息，Cancer Help UK是其子网站，但并没有提到只有英国公民才能登陆该网站，答案是D。
