2、TV Games Shows One of the most fascinating things about television is the size of the audience. A novel can be on the "best sellers" list with a sale of fewer than 100,000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything or anyone well known overnight. This is the principle behind "quiz" or "game" shows, which put ordinary people on TV to play a game for the prize and money. A quiz show can make anyone a star, and it can give away thousands of dollars just for fun. But all of this money can create problems. For instance, in the 1950s, quiz shows were very popular in the U. S. and almost everyone watched them. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show\'s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn\'t like the person who won the game, they turned the show off. Based on his story, a movie under the title " Quiz Show" is on 40 years later. Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren\'t taken as seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions. One of the TV personalities, Charles Van Doren was proved to be cheating by persuading the Show\'s producers to give him the answers beforehand. 【单选题】

A. Right

B. Wrong

C.Not mentioned

正确答案:B

答案解析:该问题句说“Charles Van Doren被证明通过劝说节目制作人事先给他答案来进行欺骗”。答案查找的线索词：Charles Van Doren(人名)和cheating(欺骗)。从第二段开始查找，不难从第二段的第五行开始找到含有Charles Van Doren的相关句，再找另一线索词：cheating，于是又进一步在该段找到直接相关行(7-10行)。对照原文和问题句，不难发现原文是说“为了吸引观众，节目制作人主动把答案事先告诉Charles Van Doren”。所以该句说法错误。

3、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 for the 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 professor of 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 or if 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 for example, 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-author Dr. 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 door to 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.The finding could prove to be useful to ____.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart disease

D.the study of longstanding mysteries

正确答案:C

答案解析:根据是第二段中：The finding，…，could open a new path for the treatment of heart diseases这一研究成果将为心脏病的医治开拓新的途径。

4、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 or cell that causes the problem and finds ways to effectively kill or contain it. In the most serious of cases, in which the entire population of a region or country 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 or disease so that, if it is encountered, one can ward it off naturally. To accomplish this, a small weak or dead 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 for the 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.The best title for the text may be____.【单选题】

A.“Vaccinations: A Blessing or A Curse”

B.“Principles of Vaccinations”

C.“Vaccines: Methods and Implications”

D.“A Miracle Cure Under Attack”

正确答案:C

答案解析:主旨题。选项C“疫苗：方法和内在含义”充分地概括说明了文章的主旨大意；而选项A、B、D均只涉及原文中的部分内容，以偏赅全，不能包含文章的全部内容。故正确答案为C。

5、ExerciseWhether or not 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 ____ of middle age and beyond. For them moderation is of vital importance. Just how much exercise a person of a given age can safely take is a question hard to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe for one person of forty but folly for another. The safe limit for exercise 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 for anyone. 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 limit themselves 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.these

B.this

C.those

D.that

正确答案:C

答案解析:本空格后面的of?middle?age?and?beyond提示了本空格要填的词应该是指“人”，而且不止一个人。从上下文看，these显然不合适，因为上文并没有特指哪些人。故C为正确答案。
