单选题It"s true that high-school coding classes aren"t essential for learning computer science in college. Students without experience can catch up after a few introductory courses, said Tom Cortina, the assistant dean at Carnegie Mellon"s School of Computer Science. However, Cortina said, early exposure is beneficial. When younger kids learn computer science, they learn that it"s not just a confusing, endless string of letters and numbers—but a tool to build apps, or create artwork, or test hypotheses. It"s not as hard for them to transform their thought processes as it is for older students. Breaking down problems into bite-sized chunks and using code to solve them becomes normal. Giving more children this training could increase the number of people interested in the field and help fill the jobs gap, Cortina said. Students also benefit from learning something about coding before they get to college, where introductory computer-science classes are packed to the brim, which can drive the less-experienced or-determined students away. The Flatiron School, where people pay to learn programming, started as one of the many coding bootcamps that"s become popular for adults looking for a career change. The high-schoolers get the same curriculum, but "we try to gear lessons toward things they"re interested in," said Victoria Friedman, an instructor. For instance, one of the apps the students are developing suggests movies based on your mood. The students in the Flatiron class probably won"t drop out of high school and build the next Facebook. Programming languages have a quick turnover, so the "Ruby on Rails" language they learned may not even be relevant by the time they enter the job market. But the skills they learn—how to think logically through a problem and organize the results—apply to any coding language, said Deborah Seehorn, an education consultant for the state of North Carolina. Indeed, the Flatiron students might not go into IT at all. But creating a future army of coders is not the sole purpose of the classes. These kids are going to be surrounded by computers—in their pockets, in their offices, in their homes—for the rest of their lives. The younger they learn how computers think, how to coax the machine into producing what they want—the earlier they learn that they have the power to do that—the better.

The people who are calling for (21) usually want the government to pay for campaigns and/or limit the mount of money that candidates and their supporters can spend. One reason that reform is (22) for is that it costs so much to run for political office. Candidates have to spend a great deal of time and effort (23) money. The incumbents (those already in office) have (24) time to do their jobs since they must attend so many fund raising events. Another (25) is the fear that candidates will be owned or controlled by the "special interest groups" that contribute to their campaigns. Sometimes this certainly seems to be the (26) . On the (27) side are those who caution that just because you call something "reform," doesn’t mean it’s really (28) .

If one person or a group of people want to tell the (32) what they think about an issue or candidate, they have to (31) advertising on TV, radio, and in newspapers and magazines. They might want to display billboards along highways and banners on heavily trafficked Web sites. All this (32) a-lot of money. Opponents of laws that regulate or limit spending say that you don’t really have freedom of speech or freedom of the press if you can’t get your message out. They say that in a democracy, the government should never be able to regulate political discussion or the means to distribute ideas.

单选题Silicon Valley likes to think of itself as morally exceptional. When Google went public in 2004, the company"s founders penned a letter to prospective shareholders that has become the Internet industry"s version of the Magna Carta. In it, they pledged that Google was "not a conventional company" but one focused on "making the world a better place." Though Silicon Valley"s newest billionaires may anoint themselves the saints of American capitalism, they"re beginning to resemble something else entirely: robber barons . Like their predecessors in railroads, steel, banking, and oil a century ago, Silicon Valley"s new entrepreneurs are harnessing technology to make the world more efficient. But along the way, that process is bringing great economic and labor dislocation, as well as an unequal share of the spoils. Take Apple"s manufacturing practices in China. By systematically outsourcing the assembly of iPhones and other gadgets to contract manufacturers like China"s Foxconn, Apple has reduced its overall cost of production and increased profit margins for shareholders. That"s neither unique nor necessarily evil. It"s a practice regularly adopted by all kinds of industries. But establishing an arm"s-length commercial relationship does not absolve a company from moral responsibility for the way its chosen partners treat workers. Labor issues at Foxconn have attracted bad press for some time. It was not until that negative publicity on New York Times last year that Apple took more meaningful action, allowing the Fair Labor Association to conduct special audits of its suppliers" factories in China. A bigger battle remains to be fought on the privacy front, where Silicon Valley"s misdemeanors are even more upsetting. Pushing the boundaries of what is generally considered acceptable, even decent, when it comes to exploiting personal information is a daily sport in the online world. That"s because a tweak here or there to the privacy settings of a social network or a tiny change to the code on a mobile application can mean a world of difference in the value of information an advertiser can access about a usually unaware user. Perhaps swayed by Silicon Valley"s altruistic spin or slow to catch up with its rapid growth, Washington has, up to now, largely left the industry to regulate itself on privacy. That"s clearly not working. Hardly a day passes without some new revelation of an Internet or mobile company stepping a byte too far into the private business of its customers. The original robber barons had decent intentions when they built railroads to connect America"s emerging cities and drilled oil wells that fueled the nation"s growth, but their empires still needed to be regulated, reined in, and in some cases broken up by vigilant watchdogs. Lofty words and ideals are fine for motivating employees and even for spurring sales, but they can also serve as cover for motives that clash with the broader interests of consumers and society. We need more than fancy promises to ensure that the rise of the Silicon Valley engineer is good for the world.

单选题We may think we know the revealing signs of lying, be it shifty eyes or nervous behaviors. Professional interrogators look for such tells, too, assuming a suspect's nervousness betrays his guilt. But interrogation can unsettle even the innocent, so nervousness alone cannot distinguish liars from truth tellers. Scientists looking for better ways to detect lies have found a promising one: increasing suspects' "cognitive load." For a host of reasons, their theory goes, lying is more mentally taxing than telling the truth. Performing an extra task while lying or telling the truth should therefore affect the liars more. To test this idea, deception researchers led by psychologist Aldert Vrij of the University of Portsmouth in England asked one group to lie convincingly and another group to tell the truth about a staged theft scenario that only the truth tellers had experienced. A second pair of groups had to do the same but with a crucial twist: both the liars and the truth tellers had to maintain eye contact while telling their stories. Later, as researchers watched videotapes of the suspects' accounts, they tallied verbal signs of cognitive load (such as fewer spatial details in the suspects' stories) and nonverbal ones (such as fewer eyeblinks). The eyeblinks are particularly interesting because whereas rapid blinking suggests nervousness, fewer blinks are a sign of cognitive load, Vrij explains--and contrary to what police are taught, liars tend to blink less. Although the effect was subtle, the instruction to maintain eye contact did magnify the differences between the truth tellers and the liars. So do these differences actually make it easier for others to distinguish liars from truth tellers? They do-- but although students watching the videos had an easier time spotting a liar in the eye-contact condition, their accuracy rates were still poor. Any group differences between liars and truth tellers were dwarfed by differences between individual participants. For example, some people blink far less than others whether or not they are lying-and some are simply better able to carry a higher cognitive load. All this makes it hard to put the study's findings into practice--especially out in the field, where the people most likely to lie are those who are good at lying. "In the real world, there's no Pinocchio-like cue that distinguishes liars from truth tellers," says study co-author Ronald Fisher of Florida International University. Magnifying subtle differences may be the next best thing.

But if you know what to look for, you can use your own senses to make weather predictions. There are many signs which can help yon. For example, in fair weather the air pressure is generally high. Tile air is still and often full of dust. Faraway objects may look hazy. But when a storm is brewing, the pressure drops and you are often able to see things more clearly. Sailors took note of this long ago and came up with a saying "The farther the sight, tile nearer the rain. ' Your sense of smell can also help you detect weather changes. Just before it rains, odors become stronger. This is because odors are {{U}}repressed{{/U}} in a fair, high-pressure center. When a bad weather low moves in, air pressure lessens and odors are released. You can also hear an approaching storm. Sounds bounce off heavy storm clouds and return to earth with increased force. An old saying describes it this way: "Sounds traveling far and wide, a storm day will betide." And don't scoff if your grandmother says she can feel a storm corning. It is commonly known that many people feel pains in their bones or in corns and bunions when the humidity rises, the pressure drops, and bad weather is on the way.

单选题Despite their many differences of temperament and of literary perspective, Emerson, Thoreau, Hawthorne, Melville, and Whitman share certain beliefs. Common to all these writers is their humanistic perspective. Its basic premises are that humans are the spiritual center of the universe and that in them alone is the clue to nature, history, and ultimately the cosmos itself. Without completely denying the existence either of a deity (the God) or of irrational matter, this perspective nevertheless rejects them as exclusive principles of interpretation and prefers to explain humans and the world in terms of humanity itself. This preference is expressed most clearly in the transcendentalist principle that the structure of the universe literally duplicates the structure of the individual self; therefore, all knowledge begins with self-knowledge. This common perspective is almost always universalized. Its emphasis is not upon the individual as a particular European or American, but upon the human as universal, freed from the accidents of time, space, birth, and talent. Thus, for Emerson, the "American Scholar" turns out to be simply "Man Thinking"; while, for Whitman, the "Song of Myself" merges imperceptibly into a song of all the " children of Adam", where " every atom belonging to me as good belongs to you. " Also common to all five writers is the belief that individual virtue and happiness depend upon self-realization, which, in turn, depends upon the harmonious reconciliation of two universal psychological tendencies: first, the self-asserting impulse of the individual to withdraw, to remain unique and separate, and to be responsible only to himself or herself and second, the self-transcending impulse of the individual to embrace the whole world in the experience of a single moment and to know and become one with that world. These conflicting impulses can be seen in the democratic ethic. Democracy advocates individualism, the preservation of the individual's freedom and self-expression. But the democratic self is torn between the duty to self, which is implied by the concept of liberty, and the duty to society, which is implied by the concepts of equality and fraternity. A third assumption common to the five writers is that intuition and imagination offer a surer road to truth than does abstract logic or scientific method. It is illustrated by their emphasis upon introspection their belief that the clue to external nature is to be found in the inner world of individual psychology--and by their interpretation of experience as, in essence, symbolic. Both these stresses presume an organic relationship between the self and the cosmos, of which only intuition and imagination can properly take account. These writers' faith in the imagination and in themselves as practitioners of imagination led them to conceive of the writer as a seer and enabled them to achieve supreme confidence in their own moral and metaphysical insights.

单选题Sporting activities are essentially modified forms of hunting behavior. Viewed biologically, the modern footballer is in reality a member of a hunting group. His killing weapon has turned into a harmless football and his prey (猎物) into a goal-mouth. If his aim is accurate and he scores a goal, he enjoys the hunter"s triumph of killing his prey. To understand how this transformation has taken place, we must briefly look back at our forefathers. They spent over a million years evolving as co-operative hunters. Their very survival depended on success in the hunting-field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They co-operated as skillful male-group attackers. Then about ten thousand years ago, after this immensely long period of hunting their food, they became farmers. Their improved intelligence, so vital to their old hunting life, was put to a new use—that of controlling and domesticating their prey. The hunt became suddenly out of date. The food was there on the farms, awaiting their needs. The risks and uncertainties of the hunt were no longer essential for survival. The skills and thirst for hunting remained, however, and demanded new outlets. Hunting for sport replaced hunting for necessity. This new activity involved all the original hunting sequences, but the aim of the operation was no longer to avoid starvation. Instead the sportsmen set off to test their skill against prey that were no longer essential to their survival. To be sure, the kill may have been eaten, but there were other, much simpler ways of obtaining a meaty meal.
