1、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 fｏｒthe 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 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 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 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. 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 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。

3、The motorcarSome pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned ａｎｄ　allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, ａｎｄ　more economical, ａｎｄ　should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable (可伸缩的) arm will ｄｒｅｐfrom the auto ａｎｄ　make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, ａｎｄ　control of the vehicle will pass to a central computer. The computer will then monitｏｒall of the car\'s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, ａｎｄ　reserve space fｏｒthe car all the way to the correct exit from the highway. The driver will then be free to relax ａｎｄ　wait fｏｒthe buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.What provides autos with electric power in an automated highway system?【单选题】

A.A rail.

B.An engine.

C.A retractable arm.

D.A computer controller.

正确答案:A

答案解析:根据常识来判断，“可伸缩得手臂”只是用来连接汽车与铁轨的工具，是能源的传导器，也就是说，提供能源的不是“可伸缩的手臂”，而“铁轨”，所以答案为A。

4、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed ｏｒsofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be upｓｅｔwhen their parents left, ａｎｄ　so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed ａｎｄ　her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professｏｒof nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care."Pamela\'s study was done against the background of a lively debate in paediatrics ａｎｄ　psychology as to the degree women should spend with children in the outside world ａｎｄ　the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to visita small child in hospital the child would be upｓｅｔａｎｄ　inconsolable (无法安慰的) fｏｒhours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope ____ mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone ａｎｄ　depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive ａｎｄ　general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handed their children over to strangers at the doｏｒof the hospital ward.""As a result of her work, parents are now recognized as partners in care ａｎｄ　are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' ａｎｄ　children\'s experience of care." 【单选题】

A.unless

B.that

C.because

D.whether

正确答案:B

答案解析:本题有一定难度，考查同位语从句引导词that的用法，此处只能用that引导同位语从句，that表示对先行词hope进行解释说明，答案是B。

5、Computer crimesMore ａｎｄ　more, the operations of our business, governments, ａｎｄ　financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information fｏｒhis own purposes can reap substantial rewards. Even worse, a number of people who have done this ａｎｄ　been caught at it have managed to get away without punishment.It\'s easy fｏｒcomputer crimes to go undetected if no one checks up on what the computer is doing, but even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected but it\'s disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections ｏｒother security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck.Fｏｒexample, a certain keypunch operatｏｒcomplained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were fｏｒdishonest transactions. In another case, dissatisfied employees of the thief tipped off the company that was being robbed unlike other lawbreakers, who must leave the country, commit suicide, ｏｒgo to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations ａｎｄ　perhaps other benefits. All too often, their demands have been met.Why? Because company executives are afraid of the bad publicity that would result if the public found out their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company\'s executives, accountants, ａｎｄ　security staff. ａｎｄ　so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.The underlying reason fｏｒthe computer criminals to get recommendations he needs is that ____.【单选题】

A.they have skills formidably difficult fｏｒothers to master

B.the employers are afraid that they would take avenge if punished

C.the employers are much afraid of bringing the public into disbelief towards them through the criminals words in open court

D.those who commit crimes do not mean bad

正确答案:C

答案解析:雇主对计算机犯罪者的宽容可能有各种原因。A、B、C、D所说的情形，在现实中都可以出现，但文中提到的只有C项，参见末段。
