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

正确答案:D

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、The Need to RememberSome people say they have no memory at all: "I just can\'t remember a thing!" But of course we all have a memory. Our memory tells us who we are. Our memory helps U. S. to make use in the present of what we have learnt in the past.In fact we have different types of memory. Fｏｒexample, our visual memory helps us recall facts ａｎｄ　places. Some people have such a strong visual memory that they can remember exactly what they have seen, fｏｒexample, pages of a book, as a complete picture.Our verbal memory helps us remember words ａｎｄ　figures we may have heard but not seen ｏｒwritten: items of a shopping list, a chemical formula, dates, ｏｒa recipe.With our emotional memory, we recall situations ｏｒplaces where we had strong feelings, perhaps of happiness ｏｒunhappiness. We also have special memories fｏｒsmell, taste, touch ａｎｄ　sound, ａｎｄ　fｏｒperforming physical movements.We have two ways of storing any of these memories. Our short-term memory stores items fｏｒup to thirty seconds-enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items fｏｒa lifetime. Older people in fact have a much biter long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance of when they were very young.Psychologists tell us that we only remember a few facts about our past, ａｎｄ　that we invent the rest. It is as though we remember only the outline ofa story. We then make up the details. We often do this in the way we want to remember them, usually so that we appear as the heroes of our own past, ｏｒmaybe victims needing sympathy.Visual memory may be used when we read a story.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:这句话仍然是在说视觉记忆，所以还应该在刚才的段落里找相关的句子加以判断，意思是：有些人有如此强大的视觉记忆以至于他们能够准确地记住他们所看见的东西，如：能够将所看过的书形成一幅完整的图画。这就说明当我们阅读书籍时人们的视觉记忆的确很重要，能够被人们加以利用。

3、Gun Rights in the US Immediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president ａｎｄ　the state governｏｒboth hurried there to share the grief. But the majority of Americans still cling to their right to own weapons. Strictly speaking, the US is not the only country where gun violence has destroyed lives, families ａｎｄ　communities in everyday circumstance. But the US is one of the few countries that seems unwilling ａｎｄ　politically incapable of doing anything serious to stop it. In countries like Britain ａｎｄ　Canada. The government adopted stricter ____ control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby ａｎｄ　the electoral system. The powerful National Rifle Association, the majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun controls anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not both; they prefer power. According to the US Bureau of Justice Statistics, firearm incidents accounted fｏｒnine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don\'t want to give up their arms they keep to protect themselves. Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professｏｒin Virginia incident had been carrying a legal weapon they might have been able to stop all this. " In his opinion, the massacre is an argument fｏｒmore people to carry, weapons, not fewer. But at the root of Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK\'s Guardian newspaper. One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American\'s responsibility to have a gun. "Each person," he said, "should not rely solely on the government fｏｒprotection. " 【单选题】

A.rifle

B.knife

C.bullet

D.gun

正确答案:D

答案解析:由于前后文的关系，应选择D，它也是本文的核心词。gun control就是枪支管理。

4、Mobile PhonesMobile phones should carry a label if they proved to be a dangerous source of radiation, according to Robert Bell, a scientist. ａｎｄ　no more mobile phone transmitter towers should be build until the long-term health effects of the electromagnetic radiation they emit is scientifically evaluated, he said. "Nobody\'s going to ｄｒｅｐdead overnight but we should be asking fｏｒmore scientific information," Robert Bell said at a conference on the health effects of low-level radiation. “If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised,” he said.A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill effects on humans from electromagnetic radiation. According to Robert Bell, there are 3.3 million mobile phones in Australia alone ａｎｄ　they are increasing by 2,000 a day. ____As well, there are 2,000 transmitter towers around Australia, many in high density residential areas. Fｏｒexample, Telstra, Optus ａｎｄ　Videophone build their towers where it is geographically suitable to them ａｎｄ　disregard the need of the community. The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child care centres, hospitals, sports playing fields ａｎｄ　residential areas with a high percentage of children. He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults. He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.Then who finances the research? According to Robert Bell, it is reasonable fｏｒthe majｏｒtelephone companies to fund it. Besides, he also urges the Government to ｓｅｔup a wide ranging inquiry in to possible health effects.【单选题】

A.He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults.

B.By the year 2000 it is estimated that Australia will have 9 million mobile phones: nearly one fｏｒevery two people.

C.“If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised,”he said.

D.Then who finances the research?

E.Fｏｒexample, Telstra, Optus ａｎｄ　Videophone build their towers where it is geographically suitable to them ａｎｄ　disregard the need of the community.

F.The conclusion is that mobile phones bring more harm than benefit.

正确答案:B

答案解析:前一句介绍了澳大利亚拥有手机的现状。选项B的内容是对到2000年年底之前手机发展前景的预测，前后内容连贯，因此是正确答案。

5、Breast Cancer Deaths Record LowThe number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year fｏｒthe first time since records began.The Cancer Research UK data showed that 11,990 women died in the UK in 2007.The previous lowest figure had been recorded in 1971-the year records began after which it rose steadily year by year until the late 1980s.ProfessｏｒPeter Johnson, Cancer Research UK\'s chief clinician said, "It\'s incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often. "Research has played a crucial role in this progress leading to improved treatments ａｎｄ　better management fｏｒwomen with the disease."The introduction of the NHS (国民保健制度) breast screening program has also contributed as women are more likely to survive the earlier cancer is diagnosed. "Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease, a 50% rise in 25 years.The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 ａｎｄ　400 deaths each year until 2004.There was a slight rise in 2005 ａｎｄ　then two years of falls.Dr Sarah Cant, policy manager at Breakthrough Breast Cancer, said, "It is great news that fewer women are dying from breast cancer ａｎｄ　highlights the impact of improved treatments, breast screening ａｎｄ　awareness of the disease. " ."However, this is still too many women ａｎｄ　incidence of the disease is increasing year by year."The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity（肥胖） ａｎｄ　alcohol consumption.Fewer women died from breast canc\'er in the UK in 2005 than in 2004.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:2005年死于乳腺癌的患者少于2004年。根据倒数第四段中：There was a slight rise in2005，可以推断该论断是错误的。
