1、PopulationThe advantages and disadvantages of large population have long been a subject of discussion among economists. ____. To feed a large population, inferior land must be cultivated and the good land worked intensively. produces less and this means a lower average income than could be obtained with a smaller population . Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify themOne of the difficulties in carrying out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, concern of government to plane a limit on the birth rate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birth rate may lead to unemployment it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.【单选题】

A.which are not likely to be built unless there is a big demand to justify them

B.It has been argued that the supply of good land is limited

C.it will be the first concern of government to plane a limit on the birth rate, whatever the consequences may be

D.Thus, each person produces less and this means a lower average income than could be obtained with a smaller population

E.A small population may mean lower productivity, but a higher average income

F.because it results in a declining market for manufactured goods

正确答案:B

答案解析:从后面一句可知，该句很可能讲述的是土地的问题。答案B说，肥沃的土地是有限的，正好与后一句所说的“开垦欠肥沃的土地并精耕细作肥沃土地”相吻合，形成语义上的连贯。

2、 More Than 8 Hours Sleep Too Much of a Good Thing 1 Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep arid feeling refreshed after a night\'s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night\'s rest may not need to set aside more than 8 hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep, for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall hack to sleep, and having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bad. "It stands to reason that if a person spends too long a time in bed, then they\'ll spend a higher percentage of time awake," he said. Long sleepers are reported to be more likely to____. 【单选题】

A.fall asleep again

B. become more energetic the following day

C.sleep less than 8 hours

D.confirm those serious consequences

E.suffer sleep problems

F.sleep more than 9 hours

正确答案:E

答案解析:选择E的依据是第六段的第一句。原文是People who slept between 9 and 10 hours earn night were more likely to report experiencing each sleep problem than people who slept 8 hours.

3、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 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 (心肌细胞), 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 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, 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, 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 (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。

4、Flu doesScratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That\'s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses-flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症), a rare but serious condition of the liver and central nervous system.There is, of course, no vaccine for the common cold but frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.If children have flu-like symptoms, their parents ____.【单选题】

A.are advised not to give them aspirin

B.should watch out for signs of Reye syndrome

C.are encouraged to take them to hospital for vaccination

D.should prevent them from mixing with people running a fever

正确答案:A

答案解析:第七段第二句直接指明了：儿童和十多岁的孩子不能服用阿司匹林来缓解伤风流感带来的疼痛，因为这有可能导致Reye综合症，会使肝脏和中枢神经系统处于少见的严重状态。

5、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 drop from 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 monitor all 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 for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the 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.In an automated highway system, all the driver needs to do is ____.【单选题】

A.keep in the right lane

B.wait to arrive at his destination

C.keep in constant touch with the computer center

D.inform the system of his destination by phone

正确答案:D

答案解析:文章的最后一段the driver will use a telephone to dial instructions about his destination into system说明本题的答案为D，即在计算机监控系统下，司机所做的不过是通过电话告诉系统自己的目的地而已。

6、Life Expectancy in the Last Hundred YearsA hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States and the United Kingdom can expect to live to about 74. Women to about 80, and these ages are rising all the time. What has brought about these changes? When we look at the life span of people 100 years ago, we need to look at the greatest killers of the time. In the early 20th century, these were the acute and oftenhighly infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.In the ____ world these diseases are far less deadly today, and in some cases have almost disappeared. A number of factors have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which make bacterial diseases much less dangerous, and vaccinations against common diseases. In addition , people\'s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.Genetically, we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those spread by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leading to more heart disease and illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.【单选题】

A.developed

B.less developed

C.undeveloped

D.developing

正确答案:A

答案解析:本句后部分说在一些国家这些病已经消失，通过常识得知应该是发达国家。

7、Vicious and Dangerous Sports Should Be Banned by LawWhen you think of the tremendous technological progress we have made, it\'s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2,000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don\'t the spectators who at tend them hope they will see some violence? Human beings remains as blood-thirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungry lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.It really is incredible that in this day and age we should still allow hunting or bullfighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a num ber of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of "the sporting spirit" is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally-admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but be cause positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned danger ous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.The main idea of this passage is____.【单选题】

A.vicious and dangerous sports should be banned by law

B.people are willing to pay vast sums money to see violence

C.to compare two different attitudes towards dangerous sports

D.people are blood-thirsty in sports

正确答案:A

8、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, or 3 ,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 for a 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 for arrows.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, or he 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 word "bandits" in paragraph 4 could be best replaced by ______. 【单选题】

A.soldiers

B.hunters

C.shooters

D.robbers

正确答案:D

答案解析:本题是词义题，比较容易。文章第四段谈到冰人当时与强盗交战，可以推测他本人有可能是强盗，另外也可以迅速查词典确定含义，答案是D。

9、Smart Window Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He\'s a professor of solid-state physics at Uppsala University in Sweden. "It\'s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they\'re stuck indoors. Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it\'s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it\'s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. What are smart windows, according to Paragraph 4? 【单选题】

A.Windows that are coated.

B.Windows that are glazed.

C.Windows the color of which can be changed.

D.Windows that have many layers.

正确答案:C

答案解析:第四段告诉我们，多年来科学家已研究出多种通过窗户节能的办法，而smart windows使用的技术使窗户能变换颜色，所以C是正确选择。

10、They say Ireland\'s the BestIreland is the best place in the world to live in for 2005, according to a life quality ranking that appeared in Britain\'s Economist magazine last week.The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being.The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life".Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality, and the high cost of living, Ireland scored an impressive 8.33 points out of 10.That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity and hunger, is rated the gloomiest (最差的) , picking up only 3.89 points."Although rising incomes and increased individual choices are highly valued, " the report said, "some of the factors associated with modernization such as the breakdown in traditional institutions and family values in part take away from a positive impact."Ireland wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life. "The magazine admitted measuring quality of life is not a straightforward thing to do, and that its findings would have their critics.No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark and Spain.The UK is positioned at No. 29, a much lower position chiefly because of the social and family breakdown recorded in official statistics. The US, which has the second highest per capita GDP after Luxembourg, took the 13th place in the survey. China was in the lower half the league at 60th.Family life in Zimbabwe is not stable.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:问题句说“在津巴布韦家庭生活是不稳定的”。题干中的核心词Family life根本就没有在文章中出现（文章中相关的句子： Zimbabwe，troubled by political insecurity and hunger，is rated the gloomiest（最差的），picking up only 3.89 points. )，判断该问题句为“没提到”。
