单选题Talking about that is useless, ______ is familiar to me.

单选题The elements other than hydrogen and helium exist in such small quantities that it is accurate to say that the universe is somewhat more than 75 percent hydrogen. Astronomers have measured the abundance of helium throughout our galaxy and in other galaxies as well. Helium has been found in old stars, in relatively young ones, in interstellar gas, and in the distant objects known as quasars. Helium nuclei have also been found to be constituents of cosmic rays that fall on the earth (cosmic "rays" are not really a form of radiation; they consist of rapidly moving particles of numerous different kinds). It doesn"t seem to make very much difference where the helium is found. Its relative abundance never seems to vary much. In some places, there may be slightly more of it; in others, slightly less, but the ratio of helium to hydrogen nuclei always remains about the same. Helium is created in stars. In fact, nuclear reactions that convert hydrogen to helium are responsible for most of the energy that stars produce. However, the amount of helium that could have been produced in this manner can be calculated, and it turns out to be no more than a few percent. The universe has not existed long enough for this figure to be significantly greater. Consequently, if the universe is somewhat more than 25 percent helium now, then it must have been about 25 percent helium at a time near the beginning. However, when the universe was less than one minute old, no helium could have existed. Calculations indicate that before this time temperatures were too high and particles of matter were moving around much too rapidly. It was only after the one-minute point that helium could exist. By this time, the universe had cooled sufficiently that neutrons and protons could stick together. But the nuclear reactions that led to the formation of helium went on for only a relatively short time. By the time the universe was a few minutes old, helium production had effectively ceased.

单选题{{B}}Passage Four{{/B}} "Sloganeering" did not originate in the 1960s. The term has a rich history. It originated from the Gaelic word slaughgharim, which signified a "host-shout," "war cry," or "gathering word or phrase of one of the old Highland clans; hence the shout or battle cry of soldiers in the field." English-speaking people began using the term by 1704. The term at the time meant "the distinctive note, phrase, or cry of any person or body of persons." Slogans were common throughout the European continent during the middle ages, and they were utilized primarily as "passwords to insure proper recognition of individuals at night or in the confusion of battle." The American revolutionary rhetoric would not have been the same without "the Boston Massacre," "the Boston Tea Party," "the shot heard around the world," and shouts of "no taxation without representation."... Slogans operate in society as "social symbols" and, as such, their intended or perceived meaning may be difficult to grasp and their impact or stimulation may differ between and among individuals and groups... Because slogans may operate as "significant symbols" or as key words that have a standard meaning in a group, they serve both expressive and persuasive functions. Harold Lasswell recognized that the influencing of collective attitudes is possible by the manipulation of significant symbols such as slogans. He believed that a verbal symbol might evoke a desired reaction or organize collective attitudes around a symbol, Murray Edelman writes that "to the political scientist patterning or consistency in the context in which specific groups of individuals use symbols is crucial, for only through such patterning do common political meaning and claims arise." Thus, the slogans a group uses to evoke specific responses may provide us with an index for the group's norm, values, and conceptual rationale for its claims. Slogans are so pervasive in today's society that it is easy to underestimate their persuasive power. They have grown in significance because of the medium of television and the advertising industry. Television, in addition to being the major advertising medium, has altered the nature of human interaction. Political images are less personal and shorter. They function as summaries and conclusions rather than bases for public interaction and debate. The style of presentation in television is more emotional, but the content is less complex or ideological. In short, slogans work well on television. The advertising industry has made a science of sloganeering. Today, communication itself is a problem because we live in an "overcommunicated" society. Advertisers have discovered that it is easier to link product attributes to existing beliefs, ideas, goals, and desires of the consumer rather than to change them. Thus, to say that a cookie tastes "homemade" or is as good as "Mom used to make" does not tell us if the cookie is good or bad, hard or soft, but simply evokes the fond memories of Mother's baking. Advertisers, then, are more successful if they present a product in a way that capitalizes on established beliefs or expectations of the consumer. Slogans do this well by crystallizing in a few words the key idea or theme one wants to associate with an issue, group, product, or event. "Sloganeering" has become institutionalized as a virtual art form; and an advertising agency may spend months testing and creating the right slogan for a product or a person. Slogans have a number of attributes that enhance their persuasive potential for social movements. They are unique and readily identifiable with a specific social movement or social movement organization. "Gray Power," for instance, readily identifies the movement for elderly Americans, and "Huelga" (strike in Spanish) identifies the movement to aid Mexican American field workers in the west and southwest.

单选题2 Today's college students are more narcissistic (自恋的) and self-centered than their predecessors, according to a comprehensive new study by five psychologists who worry that the trend could be harmful to personal relationships and American society. "We need to stop endlessly repeating 'You're special' and having children repeat that back," said the study's lead author, Professor Jean Twenge of San Diego State Universi- ty. "Kids are self-centered enough already. " "Unfortunately, narcissism can also have very negative consequences for society, including the breakdown of close relationships with others," he said. The study asserts that narcissists "are more likely to have romantic relationships that are short-lived, at risk for infidelity, lack emotional warmth, and to exhibit game-playing, dishonesty, and over-controlling and violent behaviors. " Twenge, the author of Generation Me: Why Today's Young Americans Are More Confident, Assertive, Entitled—and More Miserable Than Ever Before, said narcissists tend to lack empathy, react aggressively to criticism and favor self-promotion over helping others. Some analysts have commended today's young people for increased commitment to volunteer work. But Twenge viewed even this phenomenon skepticaiiy, noting that many high schools require community service and many youths feel pressure to list such endeavors on college applications. Campbell said the narcissism upsurge seemed so pronounced (非常明显的) that he was unsure if there were obvious remedies. "Permissiveness seems to be a component," he said. "A potential antidote would be more authoritative parenting. Less indulgence might be called for. " Yet students, while acknowledging some legitimacy to such findings, don't necessarily accept negative generalizations about their generation. Hanady Kader, a University of Washington senior, said she worked unpaid last summer helping resettle refugees and considers many of her peers to be civic-minded. But she is dismayed (气馁，灰心) by the competitiveness of some students who seem prematurely focused on career status. "We're encouraged a lot to be individuals and go out there and do what you want, and nobody should stand in your way," Kader said. "I can see goals and ambitions getting in the way of other things like relationships. " Karl Dalane, a University of Vermont sophomore, says most of her contemporaries are politically active and not overly self-centered. "People are worried about themselves—but in the sense of where they're going to find a place in the world," she said."People want to look their best, have a good time, but it doesn't mean they're not concerned about the rest of the world. " Besides, some of the responses on the narcissism test might not be worrisome, Dalane said. "It would be more depressing if people answered, 'No, I'm not special. '/
