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 fｏｒthe 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 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 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 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. 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 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.Chronic heart failure is attributed to ____.【单选题】

A.the dying heart cells

B.the effect of pharmceutical

C.the weight of a patient

D.the life span of a person

正确答案:A

答案解析:倒数第三段说：Chronic heart failure arises from heart cells dying。慢性心衰是由心肌细胞死亡导致的。

2、Outside-the-classroom Learning Makes a Big DifferencePutting a bunch of college students in charge of a $300,000 Dance Marathon, fundraiser surely sounds a bit risky. When you consider the fact that the money is supposed to be given to. Children in need of medical care, you might call the idea crazy.Most student leaders don\'t want to spend a large amount of time on something they care little about, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon\'s operations officer fｏｒtwo years.Yvonne Fangmeyer, directｏｒof the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire fｏｒfriendship was the most frequently cited reason fｏｒjoining.At large universities like Fangmeyer\'s, which has more than 40,000 students, the students, first of all, want to find a way to "belong in their own comer of campus".Katie Rowley, a Wisconsin senior, confirms the survey\'s findings. "I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find aｇｒｏｕｐof friends. "All of this talk of friendship, however, does not mean that students aren\'t thinking about their resumes. "I think that a lot of people do join to \'fatten up their resume\'," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles. "But without passion student leaders can have a difficult time trying to weather the storms that come. Fｏｒexample, in April, several student organizations at Wisconsin teamed up fｏｒan event designed to educate students about homelessness ａｎｄ　poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, ａｎｄ　dealing with the university\'s complicated bureaucracy."Outside-of the classroom learning really makes a big difference," Fangmeyer said.An extracurricular activity like raising a fund of $300,000 is risky because most student leaders ____.【单选题】

A.are lazy

B.are stupid

C.are not rich enough

D.wilt not take an interest in it

正确答案:D

答案解析:答案可以从第二段的第一句话中找到。第一句话是这么说的：大多数学生干部并不想在它们不感兴趣的事上花大量的时间。

3、GypsiesWhen school was out, I hurried to find my sister ａｎｄ　get out of the schoolyard before seeing anybody in my class. But Barbara ａｎｄ　her friends had beaten us to the playground entrance ａｎｄ　they seemed to be waiting fｏｒus. Barbara said, "So now you\'re in the A class. " She sounded impressed. "What\'s the A class?" I asked. Everybody made superiｏｒyet faintly envious giggling sounds. "Well, why did you think the teacher moved you to the front of the room, dopey? Didn\'t you know you were in the C class before, way in the back of the room?" Of course I hadn\'t known. The Wenatchee fifth grade was bigger than my whole school which had been in North Dakota, ａｎｄ　the idea of subdivisions within a grade had never occurred to me. The subdividing fｏｒthe first marking period had been done before I came to the school, ａｎｄ　1 had never, in the six weeks I\'d been there, talked to anyone long enough to find out about the A, B, ａｎｄ　C classes.I still could not understａｎｄ　why that had made such a difference to Barbara ａｎｄ　her friends. I didn\'t yet know that it was shameful ａｎｄ　dirty to be a transient laborer ａｎｄ　ridiculous to be from North Dakota. I thought living in a tent was more fun than living in a house.I didn\'t know that we were gypsies, really (how that thought would have excited me then!), ａｎｄ　that we were regarded with the suspicion felt by those who plant toward those who do not plant. It didn\'t occur to me that we were all looked upon as one more of the untrustworthy natural phenomena, drifting here ａｎｄ　there like mists ｏｒwinds. I didn\'t know that I was the only child who had camped on the Baumann\'s lａｎｄ　ever to get out of the C class. I didn\'t know that school administrators ａｎｄ　civic leaders held conferences to talk about the problem of transient laborers.I only knew that fｏｒtwo happy days I walked to school with Barbara ａｎｄ　her friends, played hopscotch ａｎｄ　jumped rope with them at class intervals, ａｎｄ　was even invited into the house fｏｒsome ginger ale --－－a strange drink I had never tasted before.The basic reason why the people in the community distrusted the transient workers was that the transient workers ____.【单选题】

A.tended to be lawbreakers

B.had little schooling

C.were afraid of strangers

D.were temporary residents

正确答案:D

答案解析:文章第四、五段指出，当地的人（农民： those who plant）用怀疑的眼光(with the suspicion)来看待他们，因为他们住帐篷， “没有固定职业，像吉普赛人（gypsies： 这里并非真指吉普赛人，而是指他们的生活方式像吉普赛人）一样游移不定，四海漂泊( drifting here ａｎｄ　there like mists ｏｒwinds)”。

5、When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction ａｎｄ　find ways to combat it. Oftentimes, success is achieved, as medical science is able to isolate the parasite, germ ｏｒcell that causes the problem ａｎｄ　finds ways to effectively kill ｏｒcontain it. In the most serious of cases, in which the entire population of a region ｏｒcountry may be at grave risk, it is deemed necessary to protect the entire population through vaccination, so as to safeguard lives ａｎｄ　ensure that the disease will not spread.The process of vaccination allows the patient\'s body to develop immunity to the virus ｏｒdisease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak ｏｒdead strain of the disease is actually injected into the patient in a controlled environment, so that his body\'s immune system can learn to fight the invader properly. Information on how to penetrate the disease\'s defenses is transmitted to all elements of the patient\'s immune system in a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped ａｎｄ　trained to deal with it, having already done so before.There are dangers inherent in the process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much fｏｒthe body to handle, resulting in the immune system succumbing, and, therefore, the patient\'s death. Such is the case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population ａｎｄ　killed massive numbers of settlers. Approximately l in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself ａｎｄ　dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3,000 Americans would be left dead.Fortunately, the smallpox virus was considered eradicated in the early 1970\'s, ending the mandatory vaccination of all babies in America. In the event of a re-introduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is truly a mixed blessing, may indeed hide some hidden curses.What does the example of the Smallpox Vaccine illustrate?【单选题】

A.The possible negative outcome of administering vaccines.

B.The practical use of a vaccine to control an epidemic disease.

C.The effectiveness of vaccines in eradicating certain disease.

D.The method by which vaccines are employed against the disease.

正确答案:A

答案解析:细节考查题。题干问的是“天花疫苗这个例子说明了什么情况”。答案参见第三段：使用疫苗可能会带来负面结果。故正确答案为A。选项B、C、D的内容都不是这个例证所谈论的观点。
