The differences in living standards around the world are vast. In 1993, the average American had an in- come of about $ 25,000. In the same year, the average Mexican earned $ 7,000, and the average Nigerian earned $1,500. Not surprisingly, this large variation in average income is reflected in various measures of the quality of life. Changes in living standards over time are also large. In the United States, incomes have historically grown about 2 percent per year (after adjusting for changes in the cost of living). At this rate, average income doubles every 35 years. In some countries, economic growth has been even more rapi D. In Japan, for instance, average income has doubled in the past 20 years, and in South Korea it has doubled in the past 10 years. What explains these large differences in living standards among countries and over time? The answer is surprisingly simple Almost all variation in living standards is attributable to differences in countries' productivity—that is, the amount of goods and services produced from each hour of a worker's time. In nations where workem can produce a large quantity of goods and services per unit of time, most people enjoy a high standard of living; in nations where workers are less productive, most people must endure a more meager existence.. Similarly, the growth rate of a nation's productivity determines the growth rate of its average income. The fundamental relationship between productivity and living standards is simple, but its implications are far-reaching. If productivity is the primary determinant of living standards, uther explanations must be of secondary importance. For example, people might think that labor unions or minimum-wage laws contributed to the rise in living standards of American workers over the past century. Yet the real hero of American workers is their rising productivity. The relationship between productivity and living standards also has great implications for public policy. When thinking about how any policy will affect living standards, the key question is how it will affect our ability to produce goods and services. To improve living standards, policymakers need to raise productivity by ensuring that workers are well educated, have the tools needed to produce goods and services, and have access to the best available technology.

判断题 Tipping is a subject that has long interested and irritated me. Many people think that the word "tip" is an acronym for "To insure promptness." However, this is not possible, I think. Since the practice of tipping began in England in the Middle Ages, scholars have not been able to find any acronyms much earlier than the 20th century. Most scholars track the word "tip" back to the early 1600s, where it originated as criminal slang. It referred to inside information. Therefore, to give another criminal a tip was to give something valuable (information) The word gradually evolved to the point where, in the late 1700s, it meant to give a monetary gratuity(tip) to someone for service performed. That's where it stayed until the English immigrated to North America. In America, the three basic occupations that require tipping are waiters/waitresses, taxi drivers, and barbers. The standard tip is now between 15 and 20 percent of the bill, depending on the quality of service. Why these three particular services deserve this special treatment is a mystery to me. Why am I supposed to tip a waiter for bringing me food when I'm not expected to tip the flight attendant on an airplane for doing the same thing? Why am I supposed to tip a cab driver, but I'm not expected to tip the bus driver? Why am I supposed to tip the barber for cutting my hair but not the dentist for fixing my teeth? I have been a teacher for 39 years. No one has ever tipped me after a particularly successful class or lecture. The whole concept of tipping doesn't make any sense. I have heard that there are some exclusive and expensive restaurants in major cities in the US where the restaurant does not give the waiters any salary at all due to the large amounts of the tips. In fact, in some instances, I read that the waiters actually pay the restaurant a small fee for the opportunity to collect the large tips. Also, I was quite surprised to learn that there was actually a website devoted to tipping and related issues(http://www.tipping.org). Some of the invisible and illogical rules of this practice are close to ridiculous. The tipping problem in many European countries is solved by automatically adding a 15 percent gratuity to the bill, I prefer the Chinese solution: no tipping at all. While I understand why China, as a developing nation, has adopted many western customs, I hope the Chinese are wise enough to never start the unnecessary practice of tipping. The level of service in China is already good enough that it doesn't need anything to make it better.

判断题The most noticeable trend among media companies is vertical integration—an attempt to control several related aspects of the media business at once, each part helping the other. Besides publishing magazines and books, Time Warner, for example, owns Home Box Office (HBO), Warner movie studios, various cable TV systems throughout the United States and CNN as well. The Japanese company Matsushita owns MCA Records and Universal Studios and manufactures broadcast production equipment. To describe the financial status of today's media is also to talk about acquisitions (并购). The media are buying and selling each other in unprecedented numbers and forming media groups to position themselves in the marketplace to maintain and increase their profits. In 1986, the first time a broadcast network had been sold; two networks were sold that year— ABC and NBC. Media acquisitions have skyrocketed(剧增) since 1980 for two reasons. The first is that most big corporations today are publicly traded companies, which means that their stock is traded on one of the nation's stock exchanges. This makes acquisitions relatively easy. A media company that wants to buy a publicly owned company can buy that company's stock when the stock becomes available. The open availability of stock in these companies means that anybody with enough money can invest in the American media industries, which is exactly how Rupert Murdoch joined the media business. The second reason for the increase in media alliances is that beginning in 1980, the Federal Communications Commission (FCC) gradually deregulated (除管制) the broadcast media. Before 1980, for example, the FCC allowed one company to own only five TV stations, five AM radio stations, and five FM radio stations; companies also were required to hold onto a station for three years before the station could be sold. The post-1980 FCC eliminated the three-year rule and raised the number of broadcast holdings allowed for one owner. This trend of media acquisitions is continuing throughout the 1990s, as changing technology expands the market for media products. The issue of media ownership is important. If only a few corporations direct the media industries in this country, the outlets for differing political viewpoints and innovative ideas could be limited.

{{B}}Passage Four{{/B}} Americans today don't place a very high value on intellect. Our heroes are athletes, entertainers, and entrepreneurs, not scholars. Even our schools are where we send our children to get a practical education-not to pursue knowledge for the sake of knowledge. Symptoms of pervasive anti-intellectualism in our schools aren't difficult to find. "Schools have always been in a society where practical is more important than intellectual," says education writer Diane Ravitch. "Schools could be a counterbalance." Razitch's latest bock, Left Back: A Century of Failed School Reforms, traces the roots of anti-intellectualism in our schools, concluding they are anything but a counterbalance to the American distaste for intellectual pursuits. But they could and should be. Encouraging kids to reject the life of the mind leaves them vulnerable to exploitation and control. Without the ability to think critically, to defend their ideas and understand the ideas of others, they cannot fully participate in our democracy. Continuing along this path, says writer Earl Shortis, "We will become a second-rate country. We will have a less civil society." "Intellect is resented as a form of power or privilege," writes historian and professor Richard Hofstadter in Anti-Intellectualism in American life, a Pulitzer Prize winning book on the roots of anti-intellectualism in US politics, religion, and education. From the beginning of our history, says Hofstadter, our democratic and populist urges have driven us to reject anything that smells of elitism. Practicality, common sense, and native intelligence have been considered more noble qualities than anything you could learn from a book. Ralph Waldo Emerson and other Transcendentalist philosophers thought schooling and rigorous book learning put unnatural restraints on children: "We are shut up in schools and college recitation rooms for 10 or 15 years and come out at last with a bellyful of words and do not know a thing." Mark Twain's Huckleberry Firm exemplified American anti-intellectualism. Its hero avoids being civilized—going to school and learning to read so he can preserve his innate goodness. Intellect, according to Hofstadter, is different from native intelligence, a quality we reluctantly admire. Intellect is the critical, creative, and contemplative side of the mind. Intelligence seeks to grasp, manipulate, re-order, and adjust, while intellect examines, ponders, wonders, theorizes, criticizes and imagines. School remains a place where intellect is mistrusted. Hofstadter says our country's educational system is in the grips of people who "joyfully and militantly proclaim their hostility to intellect and their eagerness to identify with children who show the least intellectual promise."

Is there something as truth? For a good many centuries "the search for truth" has been{{U}}(31) {{/U}} the noblest activity of the human mind, but the seekers after truth have come to such{{U}}(32) {{/U}} conclusions that it often seems that very little progress has been made. {{U}}(33) {{/U}} ,there are many people who reel that we are actually going backward.

多选题居室装修设计应重点考虑( )等方面的因素。

判断题Ⅰ．Too Many People Figures and numerous facts prove that there are already, and certainly that where will be, too many people. Simply calculating the lengths of time necessary to double the world's population is instructive. Impressively, the time required grows ever shorter: 6,000 years before Christ, 1,000,000 years were necessary to double the population, then about 1,650 years after Christ only 1,000 around the 1850's 200 years, in 1930's 80 years. Currently, the world's population doubles every 37 years. What would happen if the population were to continue doubling in volume every 37 years? According to recent calculations, maintaining such a rhythm of growth would result in 60 million billion people on the earth in 900 years, which represents 120 inhabitants per square meter. Optimists believe and often assert that science will indeed find solutions to the problem of overcrowding, namely by providing the means to immigrate to other planets. But this solution is totally impossible. In effect, even if it should become possible, 50 years would be sufficient for the 60 million billion persons to multiply to the point of populating Venus, Mercury, Mars, the Moon and the satellites of Jupiter and Saturn with a density equal to that of the Earth. Ⅱ．Food shortage Today, a good part of humanity suffers from malnutrition or from undernourishment. Some think that the recent scientific discoveries applied to agriculture and known under the name of "green revolution" will resolve the problem. Nothing is less certain. Promoters of the revolution themselves believe that it can offer only a respite of ten or twenty years. In underdeveloped countries, although mostly agricultural, the lag in food production in relation to population growth increases more and more. As the crisis worsens these countries will have to import food. But from where? Ⅲ．A Dying Planet The world's population explosion is the source of a whole series of environmental deteriorations, which in time can have disastrous consequences. Because the population—food imbalance makes it necessary to increase agricultural production "at any price", methods often harmful to the environment are used without judgment. For example, the construction of huge dams to irrigate hundreds of thousands of acres can in fact provoke catastrophes. Thus, the Aswan Dam currently prevents the deposit of fertile silts brought each year by the flooding of the Nile. The result will obviously be a decrease in the fertility of the Delta lands. Damming the Mekong risks the same consequences for Vietnam and neighbouring countries. Fertilizers, synthetic pesticides, DDT can be devastating, transforming complex ecosystems, necessary for the conservation of the environment, into simple ecosystems. Certain situations are perceived as dangerous only when they become critical enough to cause numerous deaths. Smog is an example. In London in 1952 it caused some 4,000 deaths. This incident provoked an awakening of conscience and resulted in decisions, which have proven effective. But smog presents still other dangers: namely, it destroys plants which offer little resistance, and whose oxygen production is indispensable to us, and it changes the earth's thermal equilibrium. For these forms of pollution as for all the others, the destructive chain of cause and effect goes back to a prime cause: "too many cars, too many factories, too many detergents, too many pesticides, more and more trails left by supersonic jets, inadequate methods for disinfecting sewers, too little water, too much carbon monoxide. The cause is always the same: too many people on the earth./

判断题In 1998 consumers could purchase virtually anything over the Internet. Books, compact discs, and even stocks were available from World Wide Web sites that seemed to spring up almost daily. A few years earlier, some people had predicted that consumers accustomed to shopping in stores would be reluctant to buy things that they could not see or touch in person. For a growing number of time-starved consumers, however, shopping from their home computer was proved to be a convenient alternative to driving to the store. A research estimated that in 1998 US consumers would purchase $7.3 billion of goods over the Internet, double the 1997 total. Finding a bargain was getting easier owing to the rise of online auctions and Web sites that did comparison shopping on the Internet for the best deal. For all the consumer interest, retailing in cyberspace was still a largely unprofitable business, however. Internet pioneer Amazon. com, which began selling books in 1995 and later branched into recorded music and videos, posted revenue of $153.7 million in the third quarter, up from $37.9 million in the same period of 1997. Overall, however, the company's loss widened to $45.2 million from $9.6 million, and analysis did not expect the company to turn a profit until 2001. Despite the great loss, Amazon. com had a stock market value of many billions, reflecting investors' optimism about the future of the industry. Internet retailing appealed to investors because it provided an efficient means for reaching millions of consumers without having the cost of operating conventional stores with their armies of salespeople. Selling online carried its own risks, however. With so many companies competing for consumers' attention, price competition was intense and profit margins thin or nonexistent. One video retailer sold the hit movie Titanic for $9.99, undercutting (削价) the $19.99 suggested retail price and losing about $6 on each copy sold. With Internet retailing still in its initial stage, companies seemed willing to absorb such losses in an attempt to establish a dominant market position.

判断题Migration is usually defined as "permanent or semi-permanent change of residence". However our concern is with movement between nations, not with internal migration within nations, although such movements often exceed international movements in volume. Today, the motives of people who move short distances are very similar to those of international migrants. Students of human migration speak of "push" and "pull" factors, which influence an individual's decision to move from one place to another. Push factors are associated with the place of origin. A push factor can be as simple and mild a matter as difficulty in finding a suitable job, or as traumatic as war, or severe famine. Obviously, refugees who leave their homes with guns pointed at their heads are motivated almost entirely by push factors (although pull factors do influence their choice of destination). Pull factors are those associated with the place of destination. Most often these are economic, such as better job opportunities or the availability of good land to farm. In general, pull factors add up to an apparently better chance for a good life and material well-being than is offered by the place of origin. When there is a choice between several attractive potential destinations, the deciding factor might be a non-economic consideration such as the presence of relatives, friends, or at least fellow countrymen already established in the new place who are willing to help the newcomers settle in. Besides push and pull factors, there are what the sociologists call "intervening obstacles". Even if push and (or) pull factors are very strong they still may be outweighed by intervening obstacles, such as the distance of the move, the trouble and cost of moving, the difficulty of entering the new country, and the problems likely to be encountered on arrival. The decision to move is also influenced by "personal factors" of the potential migrant. The prospect of packing up everything and moving to a new and perhaps very strange environment may appear interesting and challenging to an unmarried young man and appallingly difficult to a slightly older man with a wife arid small kids. Similarly, the need to learn a new language and customs may excite one person and frighten another. Regardless of why people move, migration of large numbers of people causes conflict. The United States and other western countries have experienced adjustment problems with each new wave of immigrants. It has usually taken several decades for each group to be accepted into the mainstream of society in the host country.

判断题If I were asked to give what I consider the single most useful bit of advice for all humanity, it would be this: Expect trouble as an inevitable part of life and, when it comes, hold your head high, look it squarely in the eye and say, "I will be bigger than you. You can not defeat me." Then repeat to yourself the most comforting of all words. "This too shall pass." To forgive oneself in the face of a devastating experience is perhaps the most difficult of life's challenges. Most of us find it much easier to forgive others. In many instances we can't control what happens to us, but we can control our reactions to what happens to us. We can stay down for the count and be carried out of the ring or we can pull ourselves back to our feet. If we are victimized by others, we must refuse to give them the power to break our spirit, make us physically ill, perhaps even shorten our lives. Most doctors will tell you that worry, anxiety, tension and anger can make you sicker than a virus. The expression "nervous breakdown" suggested that nerves have broken down, but organically the nerves are healthy. The problem is purely emotional. A doctor on the staff of the Mayo Clinic has said the majority of patients in hospital beds today are there because of illnesses that were psycho-generated. This means the sickness was triggered by an unresolved problem. I believe in blind faith. I have known people who have suffered deep personal tragedies, and this faith has helped them. But I also believe in the efficacy of positive action to overcome grief. Time is a healer, but those who help time using it wisely and well make a more rapid adjustment. Grief, in part, is self-pity turned inside out. The widow who cries, "He was everything to me. How can I go on without him?" is crying for herself, not for him. The mourner who refuses to let go of his grief eventually isolated himself from his friends. The world may stop for a few hours, or perhaps a few days, to hold a hand or to wipe away a tear, but friends and relatives have problems of their own. Life goes on—and those who refuse to go on with it are left alone to wallow in their misery. The best prescription for a broken heart is activity. I don't mean plunging into a social whirl or running off on trips. Too many people who try to escape by doing just that succeed only in taking their troubles with them. The most useful kind of activity involves doing something to help others. I have told thousands of depressed people, "Enough of this breast-beating. No matter how bad things are with you, there is someone who is worse off—and you can help him." Most touching to me is the heroism, the courage and faith of the average people in the world. Often readers who write about a problem will add something about their personal lives. I am moved by the magnificent people who write such lines as "My husband lost his sight shortly after we married, but we manage beautifully." or, "I've had two operations for cancer, but I know I'll be able to attend my son's graduation in June and I'm so thankful for that." Decide whether the statements are True or False according to the passage.

While it is true that Americans believe climbing the educational ladder leads to success, they are less certain that intellectual achievement is the only important factor leading to success. A competitive personality is seen as important to success, especially in men. The development of social and political skills is also considered to be very important. To help Americans develop these other important skills, schools have added a large number of extracurricular (课程) activities to daily life at school. This is especially true of high schools and colleges and ex tends down into elementary schools as well. Athletics, frequently called "competitive sports," are perhaps the most important of these activities. Football, basketball, and baseball teams are seen as very important in teaching students, particularly boys, the "winning spirit". At times, athletic teams seem to become more important to some students and their parents than the academic programs offered by the schools.

{{B}}Passage Three{{/B}} Nowadays, we hear a lot about the growing threat of globalization, accompanied by those warnings that the rich pattern of local life is being undermined, and many dialects and traditions are becoming extinct. But stop and think for a moment about the many positive aspects that globalization is bringing. Read on and you are bound to feel comforted, ready to face the global future, which is surely inevitable now. Consider the Internet, that prime example of our shrinking world. Leaving aside the all-to-familiar worries about pornography and political extremism, even the most narrow-minded must, admit that the net offers im-measurable benefits, not just in terms of education, the sector for which it was originally designed, but more importantly on a global level, the spread of news and comment. It will be increasingly difficult for politicians to maintain their regimes of misinformation, as the oppressed will not only find support and comfort, but also be able to organize themselves more effectively. MTV is another global provider that is often criticized for imposing popular calture on the unsuspecting millions around the worlD. Yet the viewers judgement on MTV is undoultedly positive; it is regarded as in- dispensable by most of the global teenage generation who watch it, a vital part of growing up. And in the final analysis,what harm can a few songs and videos cause? Is the world dominance of brands like Nike and Coca- Cola so bad for us when all is said and done? Sportswear and soft drinks are harmless products when com- pared to the many other things that have been globally available for a longer period of time—heroin and cocaine, for example. In any case, just because Nike shoes and Coke cans are for sale, it doesn't mean you have to buy them—even globalization cannot deprive the individnal of his free will. Critics of globalization can stop issning their doom and gloom statements. Life goes on, and has more to offer for many citizens of the world than it did for their parents’generatiorn.

判断题There are some unique problems in international trade and companies doing business overseas must be aware of them. In particular, these include (a) cultural problems, (b) monetary conversion, and (c) trade barriers. When companies do business overseas, they come in contact with people from different cultures. These individuals often speak a different language and have their own particular custom and manners. These differences can create problems. For example, in France, business meetings begin promptly at the designated time and everyone is expected to be there. Foreign business people who are late are often left outside to cool their heels as a means of letting them know the importance of promptness. Unless one is aware of such expected behaviors he may end up insulting the people with whom he hopes to establish trade relations. A second traditional problem is that of monetary conversion. For example, if a transaction is conducted with Russia, payment may be made in rubles. Of course, this currency is of little value to the American firm. It is, therefore, necessary to convert the foreign currency to American dollars. How much are these Russian rubles worth in terms of dollars? This conversion rate is determined by every market, where the currencies of countries are bought and sold. Thus there is an established rate, although it will often fluctuate from day to day. For example, the ruble may be worth $0.75 on Monday and $0.72 on Tuesday because of all announced wheat shortage in Russia. In addition, there is the dilemma associated with converting at $0.72. Some financial institutions may be unwilling to pay this price, feeling that the ruble will sink much lower over the next week. As a result, conversion may finally come at $0.69. These "losses" must be accepted by the company as one of the costs of doing business overseas. A third unique problem is trade barriers. For one reason or another, all countries impose trade barriers on certain goods crossing their borders. Some trade barriers are directly related to exports. For example, the United States permits strategic military material to be shipped abroad only after government permission has been obtained. Most trade barriers, however, are designed to restrict imports. Two of the most common import barriers are quotas and tariffs. A quota is a quantitative restriction that is expressed in terms of either physical quantity or value. For example, a quota that states that no more than 50000 Class A widgets may be imported from Europe each year is a restriction stated in terms of physical quantity. Meanwhile, a quota that restricts the importation of a certain type of Japanese glassware to no more than $1 million worth a year is stated in terms of value. A tariff is a duty or fee levied on goods being imported into the country. These tariffs can be of two types: revenue or protective. A revenue tariff is designed to raise money for the government. These tariffs are usually low, often amounting to less than twenty-five cents per item or pound. A protective tariff is designed to discourage foreign businesses from shipping certain goods into the country. The basic reason for a protective tariff is to keep out goods that will undersell products made in the home country. For this reason, protective tariffs are often very high, thus forcing the foreign business to raise its prices to cover the tariff.

判断题It is all very well to blame traffic jams, the cost of petrol and the quick pace of modern life, but manners on the roads are becoming horrible. You might tolerate the rude and inconsiderate driver, but nowadays the well-mannered motorist is the exception to the rule. Perhaps the situation calls for a "Be Kind to Other Drivers" campaign, otherwise, it may get completely out of hand. Road politeness is not only good manners, but good sense too. It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behaviors. On the other hand, a little politeness goes a long way towards relieving the tensions of motoring. A friendly nod or a wave of acknowledgement in response to an act of politeness helps to create an atmosphere of goodwill and tolerance, which is so necessary in modern traffic conditions. But such acknowledgements of politeness are all too rare today. Many drivers nowadays don't even seem able to recognize politeness when they see it. However, improper politeness can also be dangerous. A typical example is the driver who waves a child across a crossing into the path of oncoming vehicles that may be unable to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they care to. A veteran driver, whose manners are faultless, told me it would help if motorists learn to filter correctly into traffic streams one at a time without causing the total blockages (堵塞) that give rise to bad temper. Unfortunately, modern motorists can't even learn to drive, let alone be well-mannered on the road. Years ago the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users. It is high time for all of us to take this message to heart.

Emerson, according to the text, is probably ______.

Children live in a world in which science has tremendous importance. During their lifetimes it will affect them more and more. In time, many of them will work at jobs that depend heavily on science—for example, concerning energy sources, pollution control, highway safety, wilderness conservation, and population growth, and population growth. As taxpayers they will pay for scientific research and exploration. And, as consumers, they will Be bombarded(受到轰击) by advertising, much of which is said to be based on science. Therefore, it is important that children, the citizens of the future, become functionally acquainted with science-with the process and spirit of science, as well as with its facts and principles. Fortunately, science has a natural appeal for youngsters. They can relate it to so many things that they encounter—flashlights, tools, echoes, and rainbows. Besides, science is an excellent medium for teaching far more than content. It can help pupils learn to think logically, to organize and analyse ideas. It can provide practice in communication skills and mathematics. In fact, there is no area of the curriculum to which science cannot contribute, whether it is geography, history, language arts, music, or art! Above all, good science teaching leads to what might be called a "scientific attitude." Those who possess it seek answers through ohserving, experimenting, and reasoning, rather than blindly accepting the pronouncements of others. They weigh evidence carefully and reach conclusions with caution. While respecting the opinions of others, they expect honesty, accuracy, and objectivity and are on guard against hasty judgments and sweeping generalizations. All children should be developing this approach to solving problems, but it cannot be expected to appear automatically with the mere acquisition of information. Continual practice, through guided participation, is needed.

At the end of the U. S. Civil War, about four million slaves were freed. Now, people around the world can hear some of the former slaves' stories for the first time ever, as told in their own voices. "That was inslavery time, "says Charlie Smith in one interview. "They sold the colored people. And they were bringing them from Africa. They brought me from Africa. I was a child." The Library of Congress released the collection of recordings, Voices from the Days of Slavey, in January. The recorrdings were made between 1932 and 1975. Speaking at least 60 years after their emancipation(解放) ,the story teller discuss their experiences as slaves. They also tell about their lives as free men and women. Isom Moseley was just a boy at the time of emancipation, but he recalls that things were slow to change. "It was a year before the folks knowed they was free," he says. Michael Taft, the head of the library's archive of folk culture, says the recordings reveal something that written stores cannot. "The power of hearing someone speak is so much greater than reading someming from the page," Taft says. "It's how something is said—the dialect, the low pitches, the pauses--that helps tell the Story./
