that their hearts do not lose their pumping power with age. “We have found that the power of the ma le heart falls by 2025 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK. “Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, onethird of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.” What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70yearold woman’s heart could perf orm almost as well as a 20yearold one’s. “This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink. The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles being smaller and weaker as they age. 12. The text mainly talks about ______. A. men’s heart cells B. women’s aging process C. the gender difference D. hearts and long life 13. According to the text, the UK scientists have known that ______________. A. women have more cells than men when they are born B. women can replace the cells that enable the heart to beat C. the female heart loses few of the cells with age D. women never lose their pumping power with age 14. If you want to live longer, you should ___________. A. enable your heart to beat much faster B. find out the reason for aging C. exercise regularly to keep your heart healthy D. prevent your cells from being lost 15. We can know from the passage that __________. A. the reason why aging takes a greater loss on the male heart has been found out B. scientists are on the way to finding out why the male heart loses more of the cells C. the team has done something to prevent the male from suffering the greater loss D. women over 70 could lose more heart cells than those at the age of 20 第二节 (共 5 小题；每小题 2分 , 满分 10分 ) Last month, students from one hundred and three universities in eightyeight countries took part in an international puter programming contest. The Battle of the Brains took place in Harbin, China. 16 Jerry Cain, coach of Stanford University Team, California, says “One of the programming problems was trying to figure out how to break a chocolate bar into a certain number of pieces of a certain number of sizes and to do it as quickly as possible. 17 ” The students first listed the problems in order of difficulty. 18 They designed ways to test their solutions. And they wrote needed software systems. Even the winning team from Shanhai Jiaotong University in China was not able to solve all the problems within the given time limit. Stanford’s team solved five problems and finished in 14th place. Stanford was one of twentyone American universities that took part in the contest this year. 19 . It began in 1970 at Texas A and M University. The contest quickly became popular in the United States and Canada. It developed and grew as more and more schools took part in local and area contests. The first final petition was held in 1977 at the Association for Computer Machinery Computer Science Conference. Today, a work of universities holds area petitions that send the winners to the world finals, now anized by IBM. Contest spokesman Doug Heintzman says the world champions receive prizes and scholarships. 20 A. The petitors show great interest in IBM. B. Th。
