1、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.It is implied in the third paragraph that ____.【单选题】

A.many more computer crimes go undetected than are discovered

B.the rapid increase of computer crimes is a troublesome problem

C.most computer criminals are smart enough to cover up their crimes

D.most computer criminals who are caught blame their bad luck

正确答案:A

答案解析:文章的第三段指出，“究竟有多少计算机犯罪，我们没有确切的统计数字，令人不安的是很多计算机犯罪是偶然中被发现的，而不是系统的检查或者通过其他安全防范措施而发现的。”这说明A是正确的：没有被发现的计算机犯罪比被发现的计算机犯罪要多得多。

2、The IcemanOn a September day in 1991, two Germans were climbing the mountains between Austria ａｎｄ　Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, ｏｒ3 ,200 meters) , the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual ａｎｄ　so the body had come to the surface.It was lying face downward. The skeleton (骨架) was in perfect condition, except fｏｒa wound in the head, There was still skin on the bones ａｎｄ　the remains of some clothes. The hands were still holding the wooden handle of an ax ａｎｄ　on the feet there were very simple leather ａｎｄ　cloth hoots. Nearby was a pair of gloves made of tree bark (树皮) ａｎｄ　a holder fｏｒarrows.Who was this man? How ａｎｄ　when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before ａｎｄ　whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousａｎｄ　years old.With modern dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 B. C. , he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story, A new kind of X - ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage ａｎｄ　bleeding. He almost certainly died from this wound, ａｎｄ　not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war, ｏｒhe may have been fighting bandits. He may even have been a bandit himself.By studying his clothes ａｎｄ　tools, scientists have already learned a great deal from the Iceman about the times he lived in. We may never know the full story of how he died, but he has given us important clues to the history of those distant times.The body of the Iceman was found in the mountains mainly because ______.【单选题】

A.two Germans were climbing the mountains

B.the melted ice made him visible

C.he was lying on the ice

D.he was just on a mountain pass

正确答案:B

答案解析:本题是细节题，难度不大，针对文章第一段出题，比较容易找到答案依据。文中第一段最后谈到，由于1991年特别暖和，山上的冰比原来化的要多，所以尸体就露出来了，回来看选项，找信息提示，答案是B。

3、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.The finding could prove to be useful to ____.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart disease

D.the study of longstanding mysteries

正确答案:C

答案解析:根据是第二段中：The finding，…，could open a new path fｏｒthe treatment of heart diseases这一研究成果将为心脏病的医治开拓新的途径。

4、Driving after drinkingThe legal ｌｉｍｉｔfｏｒdriving after drinking alcohol is 80 milligrams of alcohol in 100 millilitres of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, what you\'ve just eaten ａｎｄ　what sort of drinks you\'ve had. Some people might reach their ｌｉｍｉｔafter only about three standard drinks.In fact, your driving ability can be affected by just one ｏｒtwo drinks. Even if you\'re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.It takes about an hour fｏｒthe body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking in the evening you might find that your driving ability is still affected the next morning, ｏｒyou could even find that you\'re still over the legal limit. In addition, if you\'ve had a few drinks at lunchtime, another one ｏｒtwo drinks in the early evening may well put you over the legal limit.In a test with professional drivers, the more alcoholic drinks they had had, the more certain they were that they could drive a test course through a ｓｅｔof movable posts…ａｎｄ　the less able they were to do it! So the only way to be sure you\'re safe is not to drink at all.Alcohol is a majｏｒcause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, ａｎｄ　road accidents after drinking are the biggest cause of death among young men. More than half of the people stopped by the police to take a breath test have a blood alcohol concentration of more than twice the legal limit.It is important to remember that driving after you\'ve been drinking doesn\'t just affect you. If you\'re involved in an accident it affects a lot of other people as well, not least the person you might kill ｏｒinjure.You might be accused of drunk driving when____.【单选题】

A.you drive upon having some drinks

B.you become a helpless alcohol addict

C.your driving is found abnormal fｏｒdrinking

D.your alcohol percentage fails the test

正确答案:C

答案解析:细节考查题。题干“你可能会被指控醉酒驾驶”是对第二段第二句you could still be taken to court的同义改写，因此应参考该句的后半部分“if a police officer thinks your driving has been affected by alcohol”（如果警官认为酒精已对你的驾驶产生影响），故正确答案为C。
