1、专业八级分类模拟 392 及答案解析(总分:100.00,做题时间:90 分钟)一、LANGUAGE USAGE(总题数:4,分数:100.00)Every year television stations receive hundreds of complaints about the loudness of advertisements. However, federal rules forbid the practice of making ads loud than the programming. In addition, 1 television stations always o
2、perate at the highest sound level allowing 2 for reasons of efficiency. According to one NBC executive, no difference exists in the peak sound level of ads and programming. Given this information, why do commercials sound so loud? The sensation of sound involves variety of factors in addition to 3 i
3、ts speak level. Advertisers are skilful at create the impression of 4 loudness through their expert use of such factors. One major contributor of the perceived loudness of commercials is that much 5 less variation in sound level occur during a commercial. In regular 6 programming the intensity of so
4、und varies over a large range. However, sound levels in commercials tend to stay at or near peak levels. Another “tricks of the trade“ are also used. Because low- 7 frequency sounds can mask higher frequency sounds, advertisers filter out any noises in that may drown out the primary message. In 8 ad
5、dition, the human voice has more auditory impact in the middle frequency ranges. Advertisers electronically vary voice sounds so that they stay within such a frequency band. Another approach is to write the script in which lots of consonants are used, because people are most aware of consonants than
6、 vowel sounds. Finally, 9 advertisers try to begin commercials with sounds that are highly different from that of the programming within which the commercial 10 is buried. Because people become adapted to the type of sounds coming from programming, a dramatic change in sound quality draws viewer“s a
7、ttention. For example, notice how many commercials begin with a cheerful song of some type.(分数:25.00)The United States is considered a multilingual country but it has never employed an official language policy. Even though English is clearly the dominant language, a variety of indigenous and immigra
8、nt languages are also spoken. The framers of the Constitution purposefully decided not to select an official language because of present linguistic diversity; however, due to the German 11 community“s active involvement in the Revolution, the Continental Congress published many documents in German t
9、o facilitate communication. Ultimately, the official language was never 12 specified in the U. S. Constitution. Proponents of bilingual education felt that poor academic achievement in certain students was attributed in part to insufficient 13 English instruction. They believed that because language
10、-minority 14 students were taught some subjects in their native tongue, then these students could potentially learn English by sacrificing the 15 content. Critics of bilingual education argue that this approach of instruction facilitates native language dependency and ultimately deters their progres
11、s in English language acquisition. Bilingual advocates counter this argument in stating that bilingual instruction looks at deeper issues of cultural difference and prevents the sort of alienation often empowering in “English only“ mandates. 16 The issue of bilingual education is both complicated an
12、d controversial. The range of programs, as well as the different meanings in different states, complicate the debate. The debate 17 continues and all sides offer research and studies that are 18 diametrically opposed to one another. In 1998, California voters overwhelmingly approved Proposition 227,
13、 an initiative that basically in attempts to eliminate bilingual education from its public 19 schools. The state of Arizona has mustered a different sentiment and 20 Mayor Giuliani of New York City has established a task force to investigate bilingual programs and the possibility of English immersio
14、n programs.(分数:25.00)The newborn can see the difference between various shapes and patterns from birth. He prefers patterns for dull or bright solid colors 21 and looks longer at stripes and angles than at circular patterns. Within three weeks, however, his preference shifts dramatic to the 22 human
15、 face. Why should a baby with so little visual experience attend more to human face than to any other kind of pattern? Some scientists 23 think this preference represents a built-in advantage for the human species. The object in prime importance to the physically helpless 24 infant is a human being.
16、 Babies seem to have a natural tendency to the human face as potentially awarding. Researchers also point out 25 that the newborn wisely relies more on pattern than on outline, size, or color. Pattern remains stable, and outline changes with point of 26 view; size, with distance from an object; and
17、brightness and color, with lighting. Mothers have always claimed that they could see their newborns looking at them as they held them, despite what they have 27 told. The experts who thought that perception had to await physical development and the consequence of action were wrong for several reason
18、s. Earlier research techniques were less sophisticated than what they are today. Physical skills were once used to indicate 28 perception of objectsskills like visual tracking and reaching for an object, both of them the newborn does poorly. Then, too, 29 assumptions that the newborn“s eyes and brai
19、n was too immature for 30 anything as sophisticated as pattern recognition caused opposing data to be thrown away. Since perception of form was widely believed to follow perception of more “basic“ qualities such as color and brightness, the possibility of its presence from birth was rejected.(分数:25.
20、00)Every fall, like clockwork, Linda Krentz of Beaverton, Oregon, felt her brain go on strike. “I just couldn“t get going in the morning,“ she says. “I“d get depressed and gain 10 pounds every winter and lose it again in spring. “ Then she read about 31 seasonal effective disorder, a form of depress
21、ion that occurs in 32 the fall and winter, and she saw the lightliterally. Every morning 33 now she turns in a specially constructed light box for half an hour 34 and sits in front of it to trick her brain into thinking she“s still enjoying those long summer days. It seems to work. Krentz is not alo
22、ne. Scientists estimate that 10 million Americans suffer seasonal depression and 25 million more develop 35 milder versions. But there“s never been definitive proof which 36 treatment with very bright lights makes a difference. In all, it“s hard 37 to do a double-blind test when the subjects can see
23、 for themselves whether or not the light is on. That“s why nobody has ever separated the real effects of light therapy with placebo (安慰剂) effects. 38 Until now, in three separate studies published last month, researchers report not only that light therapy works better than a placebo and that treatme
24、nt is usually more effective in the early 39 morning than in the evening. In two of the groups, the placebo problem was resolved by telling patients what they were comparing 40 light boxes to a new anti-depressant device that emits negatively charged ions. The third used the timing of light therapy
