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 ____.【單選題】

A.the dying heart cells

B.the effect of pharmceutical

C.the weight of a patient

D.the life span of a person

正確答案:A

答案解析:倒數(shù)第三段說：Chronic heart failure arises from heart cells dying。慢性心衰是由心肌細(xì)胞死亡導(dǎo)致的。

答案解析:last：最近的、過去的，與past意思一致；close：近的；near:接近的；final:最后的。

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 (可伸縮的) 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 (蜂鳴器) 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?【單選題】

A.A rail.

B.An engine.

C.A retractable arm.

D.A computer controller.

正確答案:A

答案解析:根據(jù)常識來判斷，“可伸縮得手臂”只是用來連接汽車與鐵軌的工具，是能源的傳導(dǎo)器，也就是說，提供能源的不是“可伸縮的手臂”，而“鐵軌”，所以答案為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 (不贊同) — 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 (兒科的) 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 (無法安慰的) 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 (開創(chuàng)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." 【單選題】

A.unless

B.that

C.because

D.whether

正確答案:B

答案解析:本題有一定難度，考查同位語從句引導(dǎo)詞that的用法，此處只能用that引導(dǎo)同位語從句，that表示對先行詞hope進(jìn)行解釋說明，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 ____.【單選題】

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

正確答案:C

答案解析:雇主對計(jì)算機(jī)犯罪者的寬容可能有各種原因。A、B、C、D所說的情形，在現(xiàn)實(shí)中都可以出現(xiàn)，但文中提到的只有C項(xiàng)，參見末段。
