NATURE ON DISPLAY IN AMERICAN ZOOS by Elizabeth HansonThe first zoo in the United States opened in Phil

2、adelphia in 1874, followed by the Cincinnati Zoo the next year. By 1940 there were zoos in more than one hundred American cities. The Philadelphia Zoo was more thoroughly planned and better financed than most of the hundreds of zoos that would open later but in its landscape and its mission - to bot

3、h educate and entertain - it embodied ideas about how to build a zoo that stayed consistent for decades. The zoos came into existence in the late nineteenth century during the transition of the United States from a rural and agricultural nation to an industrial one. The population more than doubled

4、between 1860 and 1900. As more middle-class people lived in cities, they began seeking new relationships with the natural world as a place for recreation, self-improvement, and spiritual renewal. Cities established systems of public parks, and nature tourism - already popular - became even more fash

5、ionable with the establishment of national parks. Nature was thought to be good for people of all ages and classes. Nature study was incorporated into school curricula, and natural history collecting became an increasingly popular pastime.At the same time, the fields of study which were previously t

6、hought of as natural history grew into separate areas such as taxonomy, experimental embryology and genetics, each with its own experts and structures. As laboratory research gained prestige in the zoology departments of American universities, the gap between professional and amateur scientific acti

7、vities widened. Previously, natural history had been open to amateurs and was easily popularized, but research required access to microscopes and other equipment in laboratories, as well as advanced education.The new zoos set themselves apart from traveling animal shows by stating their mission as e

8、ducation and the advancement of science, in addition to recreation. Zoos presented zoology for the non-specialist, at a time when the intellectual distance between amateur naturalists and laboratory-oriented zoologists was increasing. They attracted wide audiences and quickly became a feature of eve

9、ry growing and forward-thinking city. They were emblems of civic pride on a level of importance with art museums, natural history museums and botanical gardens.Most American zoos were founded and operated as part of the public parks administration. They were dependent on municipal funds, and they ch

10、arged no admission fee. They tended to assemble as many different mammal and bird species as possible, along with a few reptiles, exhibiting one or two specimens of each, and they competed with each other to become the first to display a rarity, like a rhinoceros. In the constant effort to attract t

11、he public to make return visits, certain types of display came in and out of fashion; for example, dozens of zoos built special islands for their large populations of monkeys. In the 1930s, the Works Progress Administration funded millions of dollars of construction at dozens of zoos. For the most p

12、art, the collections of animals were organised by species in a combination of enclosures according to a fairly loose classification scheme.Although many histories of individual zoos describe the 1940s through the 1960s as a period of stagnation, and in some cases there was neglect, new zoos continue

13、d to be set up all over the country. In the 1940s and 1950s, the first zoos designed specifically for children were built, some with the appeal of farm animals. An increasing number of zoos tried new ways of organizing their displays. In addition to the traditional approach of exhibiting like kinds

14、together, zoo planners had a new approach of putting animals in groups according to their continent of origin and designing exhibits showing animals of particular habitats, for example, polar, desert, or forest. During the 1960s, a few zoos arranged some displays according to animal behavior; the Br

15、onx Zoo, for instance, opened its World of Darkness exhibit of nocturnal animals. Paradoxically, at the same time as zoo displays began incorporating ideas about the ecological relationships between animals, big cats and primates continued to be displayed in bathroom-like cages lined with tiles.By t

16、he 1970s, a new wave of reform was stirring. Popular movements for environmentalism and animal welfare called attention to endangered species and to zoos that did not provide adequate care for their animals. More projects were undertaken by research scientists and zoos began hiring full-time vets as

17、 they stepped up captive breeding programs. Many zoos that had been supported entirely by municipal budgets began recruiting private financial support and charging admission fees. In the prosperous 1980s and 1990s, zoos built realisticlandscape immersionexhibits, many of them around the theme of the

18、 tropical rainforest and, increasingly, conservation moved to the forefront of zoo agendas.Although zoos were popular and proliferating institutions in the United States at the turn of the twentieth century, historians have paid little attention to them. Perhaps zoos have been ignored because they w

19、ere, and remain still, multi-purpose institutions, and as such they fall between the categories of analysis that historians often use. In addition, their stated goals of recreation, education, the advancement of science, and protection of endangered species have often conflicted. Zoos occupy a diffi

20、cult middle ground between science and showmanship, high culture and low, remote forests and the cement cityscape, and wild animals and urban people.Questions 1-7Do the following statements agree with the information given in Reading Passage 1 ?In boxes 1-7 on your answer sheet, writeTRUE if the sta

26、bout 20 minutes on Questions 14-26, which are based on Reading Passage 2 below. Can we prevent the poles from melting?A growing number of scientists are looking to increasingly ambitious technological fixes to halt the tide of global warming. Mark Rowe reports.A Such is our dependence on fossil fuel

27、s, and such is the volume of carbon dioxide we have already released into the atmosphere, that most climate scientists agree that significant global warming is now inevitable - the best we can hope to do is keep it at a reasonable level, and even that is going to be an uphill task. At present, the o

28、nly serious option on the table for doing this is cutting back on our carbon emissions, but while a few countries are making major strides in this regard, the majority are having great difficulty even stemming the rate of increase, let alone reversing it. Consequently, an increasing number of scient

29、ists are beginning to explore the alternatives. They all fall under the banner of geoengineering - generally defined as the intentional large-scale manipulation of the environment.B Geoengineering has been shown to work, at least on a small, localised scale, for decades. May Day parades in Moscow ha

30、ve taken place under clear blue skies, aircraft having deposited dry ice, silver iodide and cement powder to disperse clouds. Many of the schemes now suggested look to do the opposite, and reduce the amount of sunlight reaching the planet. One scheme focuses on achieving a general cooling of the Ear

31、th and involves the concept of releasing aerosol sprays into the stratosphere above the Arctic to create clouds of sulphur dioxide, which would, in turn, lead to a global dimming. The idea is modelled on historical volcanic explosions, such as that of Mount Pinatubo in the Philippines in 1991, which

32、 led to a short-term cooling of global temperatures by 0.5C. The aerosols could be delivered by artillery, highflying aircraft or balloons.C Instead of concentrating on global cooling, other schemes look specifically at reversing the melting at the poles. One idea is to bolster an ice cap by sprayin

33、g it with water. Using pumps to carry water from below the sea ice, the spray would come out as snow or ice particles, producing thicker sea ice with a higher albedo(the ratio of sunlight reflected from a surface)to reflect summer radiation. Scientists have also scrutinised whether it is possible to

34、 block icefjords in Greenland with cables which have been reinforced, preventing icebergs from moving into the sea. Veli Albert Kallio, a Finnish scientist, says that such an idea is impractical, because the force of the ice would ultimately snap the cables and rapidly release a large quantity of fr

35、ozen ice into the sea. However, Kallio believes that the sort of cables used in suspension bridges could potentially be used to divert, rather than halt, the southward movement of ice from Spitsbergen. It would stop the ice moving south, and local currents would see them float northwards, he says.D

36、A number of geoengineering ideas are currently being examined in the Russian Arctic. These include planting millions of birch trees: the thinking, according to Kallio, is that their white bark would increase the amount of reflected sunlight. The loss of their leaves in winter would also enable the s

37、now to reflect radiation. In contrast, the native evergreen pines tend to shade the snow and absorb radiation. Using ice-breaking vessels to deliberately break up and scatter coastal sea ice in both Arctic and Antarctic waters in their respective autumns, and diverting Russian rivers to increase col

38、d-water flow to ice-forming areas, could also be used to slow down warming, Kallio says. You would need the wind to blow the right way, but in the right conditions, by letting ice float free and head north, you would enhance ice growth.E But will such ideas ever be implemented? The major counter-arg

39、uments to geoengineering schemes are, first, that they are a cop-out that allow us to continue living the way we do, rather than reducing carbon emissions; and, second, even if they do work, would the side-effects outweigh the advantages? Then theres the daunting prospect of upkeep and repair of any

40、 scheme as well as the consequences of a technical failure. I think all of us agree that if we were to end geoengineering on a given day, then the planet would return to its pre-engineered condition very rapidly, and probably within 10 to 20 years, says Dr Phil Rasch, chief scientist for climate cha

41、nge at the US-based Pacific Northwest National Laboratory. Thats certainly something to worry about. I would consider geoengineering as a strategy to employ only while we manage the conversion to a non-fossil-fuel economy. The risk with geoengineering projects is that you can “overshoot“, says Dr Da

42、n Lunt, from the University of Bristol. You may bring global temperatures back to pre-industrial levels, but the risk is that the poles will still be warmer than they should be and the tropics will be cooler than before industrialisation.F The main reason why geoengineering is countenanced by the ma

43、instream scientific community is that most researchers have little faith in the ability of politicians to agree - and then bring in - the necessary carbon cuts. Even leading conservation organisations believe the subject is worth exploring. As Dr Martin Sommerkorn, a climate change advisor says, But

44、 human-induced climate change has brought humanity to a position where it is important not to exclude thinking thoroughly about this topic and its possibilities despite the potential drawbacks. If, over the coming years, the science tells us about an ever-increased climate sensitivity of the planet

45、- and this isnt unrealistic - then we may be best served by not having to start our thinking from scratch.Questions 14-18Reading Passage 2 has six paragraphs, A-F.Which paragraph contains the following information?Write the correct letter, A-F, in boxes 14-18 on your answer sheet.

48、 your answers in boxes 19-23 on your answer sheet. Geoengineering projectsA range of geoengineering ideas has been put forward, which aim either to prevent the melting of the ice caps or to stop the general rise in global temperatures. One scheme to discourage the melting of ice and snow involves in

49、troducing 1to the Arctic because of their colour. The build-up of ice could be encouraged by dispersing ice along the coasts using special ships and changing the direction of some 2but this scheme is dependent on certain weather conditions. Another way of increasing the amount of ice involves using
