单选题Smoking Since 1939, numerous studies have been conducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and indicates that there is a serious health risk. Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy. Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the throat and is believed to be related to cancer of some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking males. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply. Apart from statistics, it might be helpful to look at what smoking tobacco does to the human body. Smoke is a mixture of gases, vaporized chemicals, minute particles of ash and other solids. There is also nicotine, which is powerful poison, and black tar. As smoke is breathed in, all those components form deposits on the membranes of the lungs. One point of concentration is where the air tube and bronchus divides. Most lung cancer begins at this point. Filters and low tar tobacco are claimed to make smoking to some extent safer, but they can only slightly reduce, not eliminate the hazards.

单选题Breakfast Studies show that children who eat breakfast do better in school. It doesn"t take much further thought to believe that adults will feel better and perform better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to skip (故意略去) breakfast. If we don"t eat breakfast, we are likely to become tired when our brains and bodies run low on fuel. By mid-morning, a lot of us grab a cup of coffee, or wolf down a sugary candy bar to wake up again. This might work for a few minutes, but by lunchtime we are hungry, bad-tempered, and perhaps our mood might make us a little more likely to make unhealthy choices at lunch. Eating a good breakfast sets the tone for the rest of the day. People who eat breakfast are generally more likely to maintain a healthy weight. Many people believe that they will lose weight if they skip meals, but that isn"t a good idea. The body expects to be refueled a few times a day, so start with a healthy breakfast. A healthy breakfast should contain some protein (蛋白质) and some fiber (纤维). Protein can come from meat, eggs, beans, or soy (大豆). Fiber can be found in whole cereals (谷物), grains or in fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with soy milk.

单选题Scotland: A Land of Wisdom In the 1740s, the famous French philosopher Voltaire said, "We look to Scotland for all our ideas of civilization." That"s not a bad advertisement for any country when it comes to attracting people to search for a first-class education. According to the American author Arthur Herman, the Scots invented the modern world itself. He argues that Scottish thinkers and intellectuals worked out many of the most important ideas on which modern life depends—everything from the scientific method to market economics. Their ideas did not just spread among intellectuals, but to those people in business, government and the sciences who actually shaped the Western world. It all started during the period that historians call the Scottish Enlightenment (启蒙运动), which is usually seen as taking place between the years 1740 and 1800. Before that, philosophy was mainly concerned with religion. For the thinkers of the Scottish Enlightenment, the proper study of humanity was mankind itself. Their reasoning was practical. For the philosopher David Hume, humanity was the right subject for philosophy because we can examine human behavior and so find real evidence of how people think and feel. And from that we can make judgments about the societies we live in and make concrete suggestions about how they can be improved for universal benefit. Hume"s enquiry into the nature of knowledge laid the foundations for the scientific method—the pursuit of truth through experiment. His friend and fellow resident of Edinburgh, Adam Smith, famously applied the study of mankind to the ways in which mankind does business. Trade, he argued, was a form of information. In pursuing our own interests through trading in markets, we all come to benefit each other. Smith"s idea has dominated modern views of economics. It also has wide applications. He was one of the philosophers to point out that nations can become rich, free and powerful through peace, trade and invention. Although the Scottish Enlightenment ended a long time ago, the ideas which evolved at that time still underpin (构成……的基础) our theories of human exchange and enquiry. It also exists in Scotland itself in an educational tradition that combines academic excellence with orientation (方向).

单选题Free Concerts in America Some of the most popular attractions across America are the many free concerts offered to public throughout the year. These involve not only amateur performers, hut professional artists as well. The public parks of many cities across the country usually have bandstands and large lawns. As a service to citizens, they rent out space to performers free of charge. Amateur groups, with nothing more than a desire to perform offer their talents freely to public. Semi-professional artists are pleased to get the chance to perform before the public to perfect their craft and nurture the hope of being discovered before beginning a professional career. Famous professionals also give free concerts to make contact with their admiring fans. Often such concerts are sponsored by a large corporate organization and offered to the public free of charge as a cultural service and support for the arts. The free concerts feature all kinds of music from rock and roll, jazz, country-western to the classics. In addition, free performances may include the plays of Shakespeare or experimental theater of modem dramatists. In New York's Central Park there has long been a summer Shakespeare festival which draws huge crowds to the free performances. Of these concerts the ones held on a summer evening in the park are the most popular. They take on a festive air. Friends and groups gather together after work and spread out a blanket on the lawn facing the performers' stage. The early comers get the best locations and enjoy a picnic supper while it is still daylight. The free seating is on a first come basis. Therefore, by the time the concert begins, as many as five thousand or more people may be in attendance. The concerts usually begin at 8 p.m. and are performed under the stars. The sound is made sufficiently loud so that no matter where one chooses to sit, he can hear very well. The only disturbance may be the sound of an overhead airplane on its final approach to an airport or the far-off siren (警笛声) of an ambulance on its way to the hospital. This matters little! What counts is to soak up the atmosphere created by the music and to be with friends in the fresh open air. The best part of it all is that it's free!

单选题 The Influence of Western Movie Why does the Western movie especially have such a hold (影响) on our inclination? Chiefly, because it offers serious insights into the problem of violence such as can be found almost nowhere else in our culture. One of the well-known peculiarities of modem civilized opinion is its refusal to acknowledge the value of violence. This refusal is a virtue, but like many virtues it involves a certain deliberate blindness and it encourages hypocrisy (虚伪). We train ourselves to be shocked or bored by cultural images of violence, and our very concept of heroism tends to be a passive one. We are less drawn to the brave young men who kill large numbers of our enemies than to the heroic prisoners who endure torture without surrendering. And in the criticism of popular culture, the presence of images of violence is often assumed to be in itself a sufficient ground for condemnation. These attitudes, however, have not reduced the element of violence in our culture but have helped to free it from moral control by letting it take on the air of "liberation". The celebration of acts of violence is left more and more to the irresponsible. The gangster (匪徒) movie, with its numerous variations belongs to a cultural "underground" which praises violence aid sets it against all our higher social attitudes. It is a more "modern" style than the Western movie, perhaps even more profound, because it confronts industrial society on its own ground-the city and because, like much of our advanced art, it gains its effects by a coarse insistence on its own narrow logic. But it is anti-social resting on fantasies of irresponsible freedom. If we are brought finally to concede to the denial of these fantasies, it is only because they have been shown to be dangerous, not because they have given way to higher values of behavior. In war movies, certainly, it is possible to present violence within a framework of responsibility. But there is the disadvantage that modern war is a co-operative enterprise in which violence is largely impersonal and heroism belongs to the group more than to the individual. The hero of a war movie is most often simply a leader supposed to be brave; you are supposed to get the job done and stay alive (this too, of course, is a kind of heroic posture, but a new and "practical" one). At its best, the war movie may represent a more civilized point of view than the Western, and if it were not continually spoiled by ideological sentimentality we might hope to find it developing into a higher form of drama. But it cannot supply the values we seek in the Western.

单选题Storms Sink Ships Rescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21 Hundreds more are missing or feared dead. The two ferries sank in different rivers near the capital city of Dhaka as strong winds and rain hit the South Asian country. The government has since banned all ferries and other boats from travelling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made for just 300, police said The second ferry carried about 100 passengers. "The number of deaths is certain to rise, " said an official in charge of the rescue work. "No one really knows how many people were on board the ferry or how many of them survived. " Ferries in Bangladesh don't always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed and 400 injured by lightning strikes, falling houses and trees and the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures, too many passengers in boats and not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation's waterways(水路)every year. And many of them are dangerously overcrowded (过度拥挤). Since1977, more than 3,000 people have died in some 260 boating accidents.

单选题{{B}}第三篇{{/B}} {{B}} Computers{{/B}} The initial impact of computers was in the area of entertainment. If you walked by a video arcade in the early 1980s, you could not have failed to notice that the use of video games was growing at what some considered an alarming rate. In 1981 the movie industry grossed $ 3 billion, video games took in an estimated $ 6 billion. That gives you some idea of just how big the computer industry had become. Video games employ the same technology as personal computers, and indeed many who bought personal computers did so primarily for playing games at home, thus saving their quarters. Though video games are not as popular as they were a few years ago, they did provide consumer with their first real reason to buy PCs. A more recent computer innovation, desktop publishing, supplies one good reason for those who write for a living to buy a PC. Desktop publishing is a deceptively simple description for an extremely complex group of hardware and software tools. You can now write text, edit text, draw illustrations, incorporate photographs, design page layouts, and print a finished document with a relatively inexpensive computer and laser printer. Although the new technology offers new freedom, there is a price to be paid for this freedom. With total control comes total responsibility. In fact, the issue of social responsibility in our new computer age has long been a topic of debate among computer enthusiasts. Some people are concerned with the long-term social effects of the so-called computer revolution. Ironically, many PC pioneers who built and marketed the first machines were 60s-style advocates of social change. They claim that while personal computer technology has the potential to make society more equal, it's having the opposite effect since upper-middle-class people can afford them and lower-class people cannot. In addition, the ways that computers are used to monitor the activities of their users have evoked anxiety about the machine. Over 7 million Americans now have their work paced, controlled, and monitored by computers. A computer is more restrictive and powerful in the way it controls people than the old-fashioned assembly line. This can lead to what some have called "tech-stress". Irritated eyes, back problems, and other physical symptoms have also been associated with the extensive use of computers. Although the personal computer may not have had the impact some predicted a decade age, the combination of computer technology with satellites and cable does promise innovations in the mass media that would have seemed astonishing just a few short years ago.
