1、The Process of AgeingAt the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is the least. Earlier, we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigor resistance which, though imperceptible (察觉不出的) at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us This decline in vigor with the passing of time is called ageing. If we escape wars, accidents and diseases, we shall eventually "die of old age", and this happens at a rate which differs little from person to person. Some of us will die sooner, a few will live longer. But there is a virtual limit on how long we can hope to remain alive, however lucky and robust we are.Normal people tend to forget this process until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigor with time was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. "They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do; and mechanical systems like a wound watch, or the sun, do in fact run out of energy. But these are not analogous to what happens when man ages. A run-down watch is still a watch and can be rewound. ____. But a watch could never repair itself it does not consist of living parts, only of metal, which wears away by friction (摩擦). We could, at one time tune, repair ourselves well enough, at least to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power.an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 of the survivors to be reduced by half again.【单选题】

A. Some old people are oppressed by the fear of death

B. an illness which at twelve would knock us over, at eighty can knock us out, and into our grave

C. and mechanical systems like a wound watch, or the sun, do in fact run out of energy

D.This decline in vigor with the passing of time is called ageing

E.And old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending

F.and this happens at a rate which differs little from person to person

正确答案:E

答案解析:从空白处的前后两句可以看出，所选句也应该围绕watch。选项E与前一句一起描述了关于手表的两种情况，供后文将手表的衰老和人的衰老作比较。

2、Online Cancer Chat with a Safety NetCancer Research UK has launched an online chat forum for cancer patients to swap (变换) stories and share experiences on how to cope with such a devastating disease.But Cancer Chat is a forum with a difference: it has an information safety net.This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" or scientifically unsound information.Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.And Rebekah Gibbs, cancer patient and star of TWs Casualty, has pledged her support for the new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer and I have had such a heart - warming response from other people going through the same thing."The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family. And with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients and their families 6,000 pages of up - to - date information that is easy to understand and explains a wide range of treatments for different types of cancer and gives details of clinical trials. There is also a UK database of cancer clinical trials.The award - winning website attracts around one million visitors a month and Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.For those who do not have access to computers and have questions about cancer, the charity\'s team of cancer information nurses are available during office hours to talk over patients\' concerns on the phone.All the statements about Rebekah Gibbs are true EXCEPT ______.【单选题】

A.she is a well - known figure in Britain

B.she got breast cancer some time ago

C.she has kept a private diary about her disease

D.she thinks highly of Cancer Chat

正确答案:C

答案解析:本题难度较大，需要认真阅读文章多个段落，找出判断依据。认真阅读文章可以发现，选项里A，B，D三项在文中都提到了，第五段谈到Rebekah的日记是公开的，不是私人的，答案是C。

3、Ten years after the event, her death still remains a puzzle.【单选题】

A.mist

B.fog

C.secret

D.mystery

正确答案:D

答案解析:事情发生10年后，她的死因仍是个谜。本题难度较大，干扰项干扰很强，主要是C项。puzzle指“困惑，不解之谜”，和mystery“神秘的”是近义词，都是指人们还暂时没有揭开谜团。C项secret指“秘密”，是指一部分人已知道真相，所以和puzzle，mystery是有区别的，最佳答案是D。

5、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.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。
