1、专业八级分类模拟 390 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)Thanks in no small part to A1 Gore and his film producers, the American public is waking up to the seriousness of global warming. That is not so widely appreciated is that unless the US government 1 acted urgently and decisivel
2、y, this problem could very quickly get 2 very much worse. For reasons both economic or political coal is poised to be the 3 fuel of choice in the coming decades as the US weans itself off foreign oil. Coal combustion generates half the US“s electricity and releases at 1.5 billion tons of carbon diox
3、ide a year. If present 4 trends continue, these figures will be more than double by 2050, much on to the detriment of the world“s climate. Without an 5 alternative fuel, the only solution is to capture and store carbon dioxide from burning coal. Overcome the engineering obstacles in the way of. larg
4、e-scale 6 sequestration of carbon dioxide will be hard enough, and the bigger 7 challenge is one of political will. US companies as yet have no incentive to capture carbon emissions. While movements at state 8 and congressional levels are pushing in the right direction, the ambiguity in the administ
5、ration“s policy is counterproductive. It is time for the US government to put price on carbon 9 emissions so utilities that invest in technologies to reduce carbon emissions will see their efforts rewarding. Such a move would not 10 only reduce the risks associated with global warming, but also go a
6、 long way to restoring America“s green credentials.(分数:25.00)A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun“s very center. It is here where is to be found the source of the energy that 11 the Sun constantly pours out into the s
7、pace as light and heat. This 12 energy is liberated at the center of the Sun as billions on billions of 13 nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and, in doing so, releases some of the energy 14 that is stored in the nuclei of atoms. The output o
8、f light and heat of the Sun requires that some 600 million tons of hydrogen are 15 converted into helium in the Sun every second. This the Sun has been done for several thousands of millions of year. 16 The nuclear energy is released at the Sun“s center as high- energy gamma radiation, a form of ele
9、ctromagnetic radiation like light and radio waves, only of very much short wavelength. This 17 gamma radiation is absorbed by atoms inside the Sun, to be reemitted at slight longer wavelengths. This radiation, in its turn, is 18 absorbed and remitted. As the energy filters through the layers of the
10、solar interior, it passes through the x-ray part of the spectrum, and eventually becoming light. At this stage, it has reached that we 19 call the solar surface, and can escape into space, without being absorbed further by solar atoms. A very small fraction of the Sun“s light and heat emitted in suc
11、h directions that, after passing 20 unhindered through interplanetary space, it hits the Earth.(分数:25.00)The interloper who seized our telephone line continued to hit us again and again for the next six months. The phone company seemed powerful. Its security folks moved us to one unlisted number 21
12、after another half a dozen times. They put special pin codes in place. They put traces on the line. And the troublemaker kept 22 breaking through. If our hacker has been truly evil and omnipotent as only 23 fictional movie hackers are, there would probably have been even worse ways he could have thr
13、eatened my privacy. He could have destroyed my credit rate. He could have eavesdropped on my 24 telephone conversations or siphoned off my e-mail. He could have called in my mortgage, discontinued my health assurance or deleted 25 my Social Security number. Still, I remember feeling violating at the
14、 time and as powerless 26 as a minnow in a flash flood. Someone was invading my private spacemy family“s private spaceand there was anything I or the 27 authorities could do. It was as close to a technological epiphany (主 显节) as I have ever been. And as I watched my personal digital hell unfold, whi
15、ch struck me that our privacymine and yours 28 has already disappeared bit by bit. Losing control of your telephone, of course, is least of it. After 29 all, most of us voluntarily give out our phone number and address when we allow ourselves to be listed in the White Pages. We make it public our in
16、terests and our purchasing habits every time we shop 30 by mail order or visit a commercial website.(分数:25.00)With the effects of globalization, increases in technology and the pace of life invade more and more areas of everyday life, and free-time has become an increasing precious and important res
17、ource. 31 For those pursuing leisure lifestyles deriving from consuming the 32 “riches“ of the leisure market and for those who are experiencing a shortage of free timea “time squeeze“ leisure may offer many benefits but also some costs. For the growing number of people looking forward to abundance
18、free time in retirement and for the 33 increasing number of young people who are experiencing reduced activity levels, and problems of overweight and reduced fitness, leisure has never been vital for ensuring individual and social health 34 and well-being. At the macro level, the social, cultural, e
19、nvironmental health and economic significance of leisure and events have been increased 35 in New Zealand and around the world. Leisure and events and areas that address these phenomenon, including play, recreation, the 36 arts, sport, festivals, celebrations, health and fitness, outdoor recreation,
20、 parks, entertainment and tourism, are important aspects of modern life and providing for these are an increasingly significant 37 feature in modern economies. They can play a vital part in enhancing social capital and quality of lives. 38 This research theme has been established to farther knowledg
21、e 39 and understanding of the ways of leisure and events, and their associated forms, contributing to individual and social health and well-being, quality of life and social, cultural, environmental and economic development. Better knowledge of these broad phenomena will inform policies to maximize
22、the benefits and minimize the costs associated to the production and consumption of leisure and events. 40 (分数:25.00)专业八级分类模拟 390 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)Thanks in no small part to A1 Gore and his film producers, the American public is waking up to the seriousness
