A great deal of attention is being paid today to the so-called digital divide—the division of the world into the info (information) rich and the info poor. And that (1) does exist today. My wife and I lectured about this looming danger twenty years ago. What was less (2) then, however, were the new, positive (3) that work against the digital divide. (4), there are reasons to be (5).There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more (6), it is in the interest of business to universalize access—after all, the more people online, the more potential (7) there are. More and more (8), afraid their countries will be left (9), want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be (10) together. As a result, I now believe the digital divide will (11) rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for (12) world poverty that we’ve ever had.Of course, the use of the Internet isn’t the only way to (13) poverty. And the Internet is not the only tool we have. But it has (14) potential.To (15) advantage of this tool, some poor countries will have to get over their outdated anti-colonial prejudices (16) respect to foreign investment. Countries that still think foreign investment is a/an (17) of their sovereignty might well study the history of (18) (the basic structural foundations of a society) in the United States. When the United States built its industrial infrastructure, it didn’t have the capital to do so. And that is (19) America’s Second Wave infrastructure—(20) roads, harbors, highways, ports and so on—were built with foreign investment.

Modern technology has put men on the moon and deciphered the human genome (基因组). But when it comes to brewing up flu to make vaccines, science still turns to the incredible edible egg. Ever since the 1940s, vaccine makers have grown large batches of virus inside chicken eggs. But given that some 36,000 Americans die of flu each year, it’s remarkable that our first line of defense is still what Secretary of Health and Human Services Tommy Thompson calls “the cumbersome and archaic egg-based production.” New cell-based technologies are in the pipeline, however, and may finally get the support they need now that the United States is faced with a critical shortage of flu vaccine. Although experts disagree on whether new ways of producing vaccine could have prevented a shortage like the one happening today, there is no doubt that the existing system has serious flaws.Each year, vaccine manufacturers place advance orders for millions of specially grown chicken eggs. Meanwhile, public-health officials monitor circulating strains of flu, and each March they recommend three strains—two influenza A strains and one B strain—for manufacturers to include in vaccines. In the late spring and summer, automated machines inject virus into eggs and later suck out the influenza-rich goop. Virus from the eggs’ innards gets killed and processed to remove egg proteins and other contaminants before being packaged into vials for fall shipment.Why has this egg method persisted for six decades? The main reason is that it’s reliable. But even though the eggs are reliable, they have serious drawbacks. One is the long lead time needed to order the eggs. That means it’s hard to make more vaccine in a hurry, in case of a shortage or unexpected outbreak. And eggs may simply be too cumbersome to keep up with the hundreds of millions of doses required to handle the demand for flu vaccine.What’s more, some flu strains don’t grow well in eggs. Last year, scientists were unable to include the Fujian strain in the vaccine formulation. It was a relatively new strain, and manufacturers simply couldn’t find a quick way to adapt it so that it grew well in eggs. “We knew the strain was out there,” recalls Theodore Eickhoff of the University of Colorado Health Sciences Center, “but public-health officials were left without a vaccine—and, consequently, a more severe flu season.”Worse, the viruses that pose the greatest threat might be hardest to grow in eggs. That’s because global pandemics like the one that killed over 50 million people between 1918 and 1920 are thought to occur when a bird influenza changes in a way that lets it cross the species barrier and infect humans. Since humans haven’t encountered the new virus before, they have little protective immunity. The deadly bird flu circulating in Asia in 1997 and 1998, for example, worried public-health officials because it spread to some people who handled birds and killed them—although the bug never circulated among humans. But when scientists tried to make vaccine the old-fashioned way, the bird flu quickly killed the eggs.1. The moon-landing is mentioned in the first paragraph to illustrate ______.2. What step is essential to the traditional production of flu vaccine?3. The foremost reason why the egg-based method is defective lies in ______.4. Which of the following is true according to the passage?5. In the author’s view, the new vaccine production method seems to be ______.

At some time in your life, you may have a strong desire to do something strange or terrible. However, chances are that you don’t act on your impulse, but let it pass instead. You know that to commit the action is wrong in some way and that other people will not accept your behavior.Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitude once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject.One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. It’s not taboo to talk about fat; it’s taboo to be fat. The “in” look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their images as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U.S., thin is “in”, fat is “out”.It’s not surprising, then, that millions of Americans have been obsessed with staying slim and “in shape”. The pursuit of a youthful physical appearance is not, however, the sole reason for Americans’ fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people’s bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising.1. From the passage we can infer taboo is ______.2. Based on the ideas presented in the passage we can conclude “being fat” ______ in American society.3. The topic of fat is ______ many other taboo subjects.4. What does “thin is ‘in’, and fat is ‘out’” mean?5. Apart from this new understanding of the correlation between health and exercise, the main reason the passage gives for why so many Americans are exercising regularly is ______.

The world has spent on preparation for war more than $112 billion a year, roughly $450 per head for every man, woman, and child in the world. Let us consider for a moment what could be done with this sum of money if it were spent on peace and not on war. Some of it, at any rate, in the more prosperous countries, could be spent on the reduction of taxation. The rest should be spent in ways that will, at the same time, be of benefit to mankind and a solution to the economic problem of change from war industry to the expansion of peace industries. As to this expansion, let us begin with the most elementary of all needs, namely, food. Today, the majority of mankind suffers from undernourishment, and in view of the population explosion, this situation is likely to grow worse in the coming decades. A very small part of what is now being spent upon weapons would improve our predicament. Not only could the American surplus of grain, which was for many years uselessly destroyed, be spent in relief of famine, but, by irrigation, large region now desert could be made fertile, and by improvement in transport, distribution from regions of excess to regions of scarcity could be helped.Housing, even in the richest countries, is often disastrously inadequate. This could be relieved by a tiny fraction of what is being spent on missiles. Education everywhere, but especially in the newly liberated countries of Africa and Asia, demands expenditure many times as great as that which it receives now. But it is not only greater expenditure that is needed in education. If the terror of war were removed, science could be devoted to improving human welfare, instead of to the invention of increasingly expensive methods of mutual killing and schools would no longer think it a part of their duty to promote hatred of possible enemies by means of ignorance hardened by lies.1. According to the passage, the problem of famine can be relieved by the following means EXCEPT ______.2. Which of the following statements is not mentioned as a benefit derived from diverting money spent on war to peaceful purposes?3. What does the word “predicament” mean in this passage?4. If the war continues, we can infer that science will be devoted to ______.5. What’s author’s attitude in the passage?

The kind of music, song, and dance a people generates, with its characteristic rhythm and beat, forms one of the best indexes of its cultural style, and in America, the dominant musical styles are blues, swing and jazz. The lyrics to this music are often foolishly sentimental and sometimes non-sensual, but frequently they embody a wild and earthy humor, or a sad and tragic strain. As distinguished from most American popular tunes, American hot music is not written to be danced to. Yet there is an internal beat in jazz which relates deeply to dance: the movements of the body interpret the music’s intent better than words can. When there is dancing, however, the dances break away from a formal pattern and, at their bat, keep with the improvisation (即兴) of the music. Unlike earlier American folk dances, which are collective, so-called ballroom dancing is performed by couples. Each couple is comparatively alone, not being well enough acquainted with the other couples on the dance floor to join them. But, in the swing dancing, as the music mounts the partners separate to execute complicated solo variations and then rejoin each other. As the music approaches one of its climaxes, the dancers pay the musicians the tribute(赞美) of gathering around to cheer them on. In popular dance and music, Americans come closer to reaching a native idiom of religious feeling than they do in any other aspect of their lives.1. The main idea of the passage is that _____.2. The difference between American hot music and most American popular tunes is that _____.3. According to the passage, the swing dancing is _____.4. Which is the relationship between jazz and dance?5. In the swing dancing, the musicians _____.
