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、BaseballThere are people in Italy who can\'t stａｎｄ　soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn ｏｒeven frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it\'s a game better suited to the 19th century, slow, quiet ａｎｄ　gentlemanly. These are the same people you may be one of them who love football because there\'s the sport that glorifies "the hit".By contrast, baseball seems abstract, cool, silent ａｎｄ　still. On TV the game is fractured into a dozen perspectives, replays ａｎｄ　close ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space ａｎｄ　time fｏｒinvolvement. The TV won\'t do it fｏｒyou.Take, fｏｒexample, the third baseman. You sit behind the third base dugout ａｎｄ　you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms ｏｒbring the glove to a point in front of him, takes a step right ｏｒleft, backward ｏｒforward, perhaps he glances across the field to check his first baseman\'s position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed".The skeptic ａｎｄ　the innocent must play the game. ａｎｄ　this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood if football is a symphony of movement ａｎｄ　theatre, baseball is chamber music, a spacious interlocking of notes, chores ａｎｄ　responses.Those who don\'t like baseball may complain that ____.【单选题】

A.it is only to the taste of the old

B.it involves fewer players than football

C.it is not exciting enough

D.it is pretentious ａｎｄ　looks funny

正确答案:C

答案解析:文章第一段指出：许多人不喜欢垒球，一提起垒球这些人就打哈欠甚至皱眉头。对他们来说，看垒球意味着眼巴巴地观望着身着运动装(outfit)的人呆立在球场上，东瞧瞧西望望，很少有什么（激动人心的）事发生，没意思透了。他们认为这样的运动更适合上个世纪的人的口味，不像橄榄球那样充满活力。A:它只适合老年人的口味。注意：说的是适合上个世纪的人的口味，意味不一样。D：矫揉造作、滑稽可笑。这与说它gentlemanly（具有绅士风度、矜持，没有冲撞或拼抢）不一样。

3、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 diseases is the most common among the local residents in Shanghai?【单选题】

A.Heart disease.

B.Breast cancer.

C.Infectious diseases.

D.Lung cancer.

正确答案:B

答案解析:细节考查题。答案参见第三段最后一句：Following breast cancer，it has the second-highest incidence rate（肺癌排在乳腺癌之后，发病率第二高）。可见最常见的疾病就是乳腺癌，故正确答案为B。

4、The motorcarSome pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned ａｎｄ　allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, ａｎｄ　more economical, ａｎｄ　should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable (可伸缩的) arm will ｄｒｅｐfrom the auto ａｎｄ　make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, ａｎｄ　control of the vehicle will pass to a central computer. The computer will then monitｏｒall of the car\'s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, ａｎｄ　reserve space fｏｒthe car all the way to the correct exit from the highway. The driver will then be free to relax ａｎｄ　wait fｏｒthe buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.What provides autos with electric power in an automated highway system?【单选题】

A.A rail.

B.An engine.

C.A retractable arm.

D.A computer controller.

正确答案:A

答案解析:根据常识来判断，“可伸缩得手臂”只是用来连接汽车与铁轨的工具，是能源的传导器，也就是说，提供能源的不是“可伸缩的手臂”，而“铁轨”，所以答案为A。

5、The Only Way Is Up Think of a modem city ａｎｄ　the first image that come to mind is the skyline. It is full of great buildings, pointing like fingers to heaven. It is true that some cities don\'t permit buildings to go above a certain height. But these are cities concerned with the past. The first thing any city does when it wants to tell the world that it has arrived is to build skyscrapers. When people gather together in cities, they create a demａｎｄ　fｏｒlａｎｄ　since cities are places where money is made, that demａｎｄ　can be met. ａｎｄ　the best way to make money out of city lａｎｄ　is to put as many people as possible in a space that covers the smallest amount of ground that means building upwards. The technology existed to do this as early as the 19th century. But the height of buildings was limited by one important factor. They had to be small enough fｏｒpeople on the top floors to climb stairs. People could not be expected to climb a mountain at the end of their journey to work, ｏｒhome. Elisha Otis, a US inventor, was the man who brought us the lift ｏｒelevator, as he preferred to call it. However, most of the technology is very old lifts work using the same pulley system the Egyptians used to create the Pyramids. What Otis did was attach the system to a steam engine ａｎｄ　develop the elevatｏｒbrake, which stops the lift falling if the cords that hold it up are broken. It was this that did the most to gain public confidence in the new invention. In fact, he spent a number of years exhibiting lifts at fairgrounds, giving people the chance to try them out before selling the idea to architects ａｎｄ　builders. A lift would not be a very good theme park attraction now. Going in a lift is such an everyday thing that it would just be boring. Yet psychologists ａｎｄ　others who study human behaviｏｒfind lifts fascinating. The reason is simple. Scientists have always studied animals in zoos. The nearest they can get to that with humans is in observing them in lifts. "It breaks all the usual conventions about the bubble of personal space we carry around with us ａｎｄ　you just can\'t choose to move away," says workplace psychologist, Gary Fitzgibbon. Being trapped in this setting can create different types of tensions, he says. Some people are scared of them. Others use them as an opportunity to get close to the boss. Some stａｎｄ　close to the door. Others hide in the comers. Most people try ａｎｄ　shrink into the background but some behave in a way that makes others notice them. There are a few people who just stａｎｄ　in a comer taking notes. Don\'t worry about them. They are probably from a university.". . . these are cities concerned with the past" in the first paragraph refer to cities that____.【单选题】

A.are worried about their past

B.have a glorious past to be proud of

C.want to maintain their traditional image

D.are very interested in their own history

正确答案:C

答案解析:be concerned with是“关心、关注”的意思顾可排除B和D两个选项，根据前面一句话，these cities是指那些不允许建筑物超出一定高度的城市，即不愿意改变固有形象的城市。
