1、英语翻译基础(英汉互译)模拟试卷 15 及答案与解析英译汉1 The balance of nature is a very elaborate and very delicate system of checks and counterchecks. It is continually being altered as climates change, as new organisms evolve, as animals or plants permeate to new areas. But the alterations have in the past, for the most p
2、art, been slow, whereas with the arrival of civilized man, their speed has been multiplied manifold: from the evolutionary time-scale, where change is measured by periods of ten or a hundred thousand years, they have been transferred to the human time-scale in which centuries and even decades count.
3、Everywhere man is altering the balance of nature. He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously. He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization. H
4、e exterminates some species on a large scale, but favours the multiplication of others. In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million.Many of these changes which he has brought about have had unforeseen consequences. Wh
5、o would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers wives would have led to Eastern Australia being overrun with forests of Prickly Pear? Who wo
6、uld have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semi desert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading
7、 of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?2 Biogas: a Solution to Many ProblemsIn almost all developing countries, the lack of adequate supplies of cheap, convenient and reliable fuel is a major problem. Rural communities depend l
8、argely on kerosene, wood and dung for their cooking and lighting needs. But kerosene is now priced out of reach of many people and wood, except in heavily forested areas, is in short supply. The search for firewood occupies a large part of the working day and has resulted in widespread deforestation
9、.Dung is in constant supply wherever there are farm animals and, when dried, it is convenient to store and use. But burning dung destroys its value as fertilizer, thus depriving the soil of a much needed source of humus and nitrogen.Rural areas of developing countries are also plagued by a lack of a
10、dequate sanitation. Improper waste disposal spreads disease, contaminates water sources and provides breeding grounds for diseasecarrying insects.The problems of improving environmental hygiene, conserving resources and finding alternative sources of fuel may be unrelated. Their solutions, however,
11、are not, as many countries experimenting with biogas technology are discovering. Biogas, a mixture of methane and carbon dioxide, is produced by the fermentation of organic matter. The process of anaerobic fermentation is a natural one, occurring whenever living matter decomposes. By containing the
12、matterand the processin a digester or biogas plant, the combustible gas can be trapped and used as fuel for household lighting and cooking. The digested slurry that remains can be used on the land as a soil conditioner and fertilizer.Biogas plants have attracted much interest in recent years and the
13、y are in use in several Asian countries: 36000 are reported in rural areas of India, 27000 in Korea and more than 80000 in China. In most countries the value of the gas has been the prime factor leading to their adoption: 70 percent of India s plants, for instance, were built during the energy and f
14、ertilizer crisis of 1975-1976although their use in that country dates back to 1951. Similarly in Thailand and Korea, biogas is being investigated as an alternative to costly charcoal ad to save compost materials from being burned.3 Preserving Water SourcesRecently we held a successful daylong worksh
15、op that was attended by local primary and secondary school teachers as well as several university students representing the environmental groups on their campuses. The workshop was unique: To convey how critical water is to the survival of society, we showed to what an extent our bodies are water an
16、d how the natural environment also revolves around it. We depicted the intimate connection between the functions of the human body and water, and further showed how human systems have parallels in nature. Our participants were amazed that, when shown on the same scale, the human cardiovascular syste
17、m of veins and arteries and an aerial view of a river system were so much alike as to be indistinguishable. We also showed them the similarities between a human bone and a tree. Nerves, when a person experiences pleasure, look relaxed and have many curves, like a healthy river that also has numerous
18、 bends and curves. We contrasted these with a picture of a nerve straight and stiff as it feels pain; alongside it we placed a picture of a river that has been manipulated by human engineering and rendered straight, unhealthy and lifeless.Once our participants had gained a new appreciation for water
19、, the urgent need to protect this precious resource became plain to them. We followed up by spending some time thinking about concrete projects that they could undertake with their students or green groups.Many great project ideas were voiced that day and some are already getting underway. A seconda
20、ry school in Tianjin is beginning a campus greening project and wants to include greywater treatment as well as rainwater collection in their plan. Students from a local university are campaigning to reduce the water usage in their bathhouses. Currently, students pay one price for a shower of unlimi
21、ted length, which invariably leads to waste. Their approach to cutting waste includes changing the pricing scheme and replacing the showerheads in their bathhouses with a water-saving type.4 Energy CrisisThe U. S. Census Bureau has estimated that the population of the United States could approach 30
