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.The human heart stops producing cardiac cells ______.【单选题】
A.when a person becomes old
B.as soon as a person gets sick
C.immediately after a person is born
D.once a person dies

答案解析:本题有一定难度,需要吃透原文句意,答案依据是文章第一段,谈到科学家发现人一生中心脏都会不停地制造新的心肌细胞,尽管新细胞产生的速度随年龄增长而放慢,换句话说,只有人死了,心脏才会停止制造心肌细胞,回来看选项,D项和原文句意相符,是答案。
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 oranyone well known overnight. This is the principle behind "quiz" or"game" shows, which put ordinary people on TV to play a game forthe prize and money. A quiz show can make anyone a star, and it can give away thousands of dollars just forfun. But all of this money can create problems. Forinstance, 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, orthat try to cause newly-married couples to fight on TV, orthat 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. The huge scandal of cheating in TV games shows was not exposed until 40 years later in the movie "Quiz Show". 【单选题】
A. Right
B. Wrong
C.Not mentioned
正确答案:B
答案解析:该问题句说“大量电视节目中的欺骗丑闻40年以后才在名为quiz show的电影中被曝光”。答案查找的线索词:40 years和Quiz Show。从第二段段末开始查找,不难从第二段的最后一句找到含有这两个线索词的直接相关句。不难发现原文并不是说“40年后该电影才曝光这一丑闻”,原句只是说“名为Quiz Show的电影在40年后才上演”,所以该句说法错误。
3、 More Than 8 Hours Sleep Too Much of a Good Thing 1 Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2 Investigators at the University of California in San Diego found that people who clock up 9 or10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep arid feeling refreshed after a night\'s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night\'s rest may not need to setaside more than 8 hours a night. He added that "it might be a good idea" forpeople who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep, forinstance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 Forthe current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall hack to sleep, and having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bad. "It stands to reason that if a person spends too long a time in bed, then they\'ll spend a higher percentage of time awake," he said. One of the sleep problems is walking in the middle of the night, unable to____.【单选题】
A.fall asleep again
B. become more energetic the following day

E.suffer sleep problems
