单选题{{B}}Passage Four{{/B}}
American culture has not been immune to
cultural influences from outside. The idea of democracy came from the ancient
Greeks; the Industrial Revolution started in England; jazz and rock music
preserve African rhythms—to pick a few examples. Indeed, many of the things we
think of as "100 percent American" came from other cultures.
Still, most of the changes in American culture over the last century have
come from within, as the result of inventions and discoveries. And change has
been dramatic. One hundred years ago the United States was largely a nation of
farmers. Many of the things we take for granted today—a high school education,
for example, or indoor plumbing—were luxuries then. The moon was a light for
lovers, not a site for scientific exploration; genetic engineering (基因工程) was
not even a subject for science fiction, much less for laboratory research and
corporate investments. The decades following the Second World War, in
particular, were characterized by spectacular scientific and technological
advances, national self-confidence, optimism, and (for many Americans)
prosperity. The American economy was the strongest in the world: more goods were
produced and sold, more people were working, and the standard of living was
higher than ever before. Polls (民意调查) taken in the 1950's and 1960's show that
the average American was preoccupied with the questions "will I make a good
living?" "Will I be successful?" and "Will I raise successful, happy children?"
Success was defined in terms of maintaining a stable family and "keeping up with
the Jones". Most Americans believed that if they played by the rules—if they
work hard and did what was expected, if they sacrificed their own needs to those
of their family and their employer—they would be rewarded with an
ever-increasing standard of living, a devoted spouse, and decent children. An
expensive car, a suburban home, and children in college were tangible (可触知的)
signs that hard work and self-sacrifice paid
off.

单选题AlphaGo"s victory over Go(围棋) champion Lee Se-dol reportedly shocked artificial intelligence experts, who thought such an event was 10 to 15 years away. But if the timing was a surprise, the outcome was not. On the contrary, it was inevitable and entirely foreseeable.
Playing complex games is precisely what computers do supremely well. Just as they beat the world champions at checkers(跳棋) and then chess, they were destined to beat the champion at Go. Yet I don"t believe, as some do, that human defeats like this one
presage
an era of mass unemployment in which awesomely able computers leave most of us with nothing to do. Advancing technology will profoundly change the nature of high-value human skills and that is threatening, but we aren"t doomed.
The skills of deep human interaction, the abilities to manage the exchanges that occur only between people, will only become more valuable. Three of these skills stand out: The first, the foundation of the rest, is empathy, which is more than just feeling someone else"s pain. It"s the ability to perceive what another person is thinking or feeling, and to respond in an appropriate way.
The second is creative problem-solving in groups. Research on group effectiveness shows that the key isn"t team cohesion or motivation or even the smartest member"s IQ; rather, it"s the social sensitivity of the members, their ability to read one another and keep anyone from dominating.
The third critical ability, somewhat surprisingly, is storytelling, which has not traditionally been valued by organizations. Charts, graphs and data analysis will continue to be important, but that"s exactly what technology does so well. To change people"s minds or inspire them to act, tell them a story.
These skills, though basic to our humanity, are fundamentally different from the skills that have been the basis of economic progress for most of human history, such as logic, knowledge and analysis, which we learned from textbooks and in classrooms. By contrast, the skills of deep human interaction address the often irrational reality of how human beings behave, and we find them not in textbooks but inside ourselves. As computers master ever more complexity, that"s where we"ll find the source of our continued value.

单选题There is no question that the old style of air pollution could kill people. In one week following the infamous "peasouper" fog in December 1952, 4,700 people died in London. Most of these people were elderly and already had heart or lung diseases. A series of these killer fogs eventually led to the British Parliament passing the Clean Air Act which restricted the burning of coal. Fortunately the effect of smog on the lungs is not so dramatic. Scientists have now conducted a number of laboratory experiments in which volunteers are exposed to ozone inside a steel chamber for a few hours. Even at quite low concentrations there is a reversible fall in lung function, an increase in the irritability of the lungs and evidence of airway inflammation (发炎). Although irritable and inflamed lungs are particularly seen in people with asthma (哮喘) and other lung diseases, these effects of ozone also occur in healthy subjects. Similar changes are also seen after exposure to nitrogen dioxide, although there is some disagreement about the concentration at which they occur. Other studies have found that people living in areas with high levels of pollution have more symptoms and worse hung function than those living in areas with clean air. Groups of children attending school camps show falls in lung function even at quite low concentrations of ozone. There is also a relationship between ozone levels and hospital admissions for asthma, both in North America and Australia. It is suspected that long-term exposure to smog may result in chronic bronchitis (支气管炎) and emphysema (肺气肿), but this has yet to be proven. Recently an association has been found between the levels of particles in the air and death rates in North American cities. The reason for this association is not understood and as yet there is no evidence this occurs in Australia. However, we do know that hazy days are associated with more asthma attacks in children.

单选题"Humans should not try to avoid stress any more than they would shun food, love or exercise." said Dr. Hans Selye, the first physician to document the effects of stress on the body. While here's no question that continuous stress is harmful, several studies suggest that challenging situations in which you're able to rise to the occasion can be good for you. In a 2001 study of 158 hospital nurses, those who faced considerable work demands but coped with the challenge were more likely to say they were in good health than those who felt they couldn't get the job done. Stress that you can manage may also boost immune(免疫的)function. In a study at the Academic Center for Dentistry in Amsterdam, researchers put volunteers through two stressful experiences. In the first, a timed task that required memorizing a list followed by a short test, subjects believed they had control over the outcome. In the second, they weren't in control: They had to sit through a gory(血淋淋的)video on surgical procedures. Those who did go on the memory test had an increase in levels of immunoglobulin(免疫球蛋白)A, an antibody that's the body's first line of defense against germs. The video-watchers experienced a downturn in the antibody. Stress prompts the body to produce certain stress hormones. In short bursts these hormones have a positive effect, including improved memory function. "They can help nerve cells handle information and put it into storage," says Dr. Bruce McEwen of Rockefeller University in New York. But in the long run these hormones can have a harmful effect on the body and brain. "Sustained stress is not good for you," says Richard Morimoto, a researcher at Northwestern University in Illinois studying the effects of stress on longevity (长寿),"It's the occasional burst of stress or brief exposure to stress that could be protective.
