Mount Kilimanjaro in Africa, portions of the South American Andes, and the Himalayas will very li

2、kely lose most of their glacial ice within the next two decades, affecting local water resources. Glacial ice continues its retreat in Alaska. NASA scientists determined that Greenlands ice sheet is thinning by about 1 m per year. The additional meltwater, especially from continental ice masses and

3、glaciers, is adding to a rise in sea level worldwide. Satellite remote sensing is monitoring global sea level, sea ice, and continental ice. Worldwide measurements confirm that sea level rose during the last century.Surrounding the margins of Antarctica, and constituting about 11% of its surface are

4、a, are numerous ice shelves, especially where sheltering inlets or bays exist. Covering many thousands of square kilometers, these ice shelves extend over the sea while still attached to continental ice. The loss of these ice shelves does not significantly raise sea level, for they already displace

5、seawater. The concern is for the possible surge of grounded continental ice that the ice shelves hold back from the sea.Although ice shelves constantly break up to produce icebergs, some large sections have recently broken free. In 1998 an iceberg (150 km by 35 km) broke off the Ronne Ice Shelf, sou

6、theast of the Antarctic Peninsula. In March 2000 an iceberg tagged B-15 broke off the Ross Ice Shelf (some 90 longitude west of the Antarctic Peninsula), measuring 300 km by 40 km. Since 1993, six ice shelves have disintegrated in Antarctica. About 8000 km of ice shelf are gone, changing maps, freei

7、ng up islands to circumnavigation, and creating thousands of icebergs. The Larsen Ice Shelf, along the east coast of the Antarctic Peninsula, has been retreating slowly for years. Larsen-A suddenly disintegrated in 1995. In only 35 days in early 2002, Larsen-B collapsed into icebergs. This ice loss

8、is likely a result of the 2.5 temperature increase in the region in the last 50 years. In response to the increasing warmth, the Antarctic Peninsula is sporting new vegetation growth, previously not seen there. A loss of polar ice mass, augmented by melting of alpine and mountain glaciers (which exp

9、erienced more than a 30% decrease in overall ice mass during the last century) will affect sea-level rise. The IPCC assessment states that “between one-third to one-half of the existing mountain glacier mass could disappear over the next hundred years.“ Also, “there is conclusive evidence for a worl

10、dwide recession of mountain glaciers. This is among the clearest and best evidence for a change in energy balance at the Earths surface since the end of the 19th century.“Sea-level rise must be expressed as a range of values that are under constant reassessment. The 2001 IPCC forecast for global mea

11、n sea-level rise this century, given regional variations, is from 0.11-0.88 m. The median value of 0.48 m is two to four times the rate of previous increase. These increases would continue beyond 2100 even if greenhouse gas concentrations are stabilized. （分数：10.40）(1).The word confirm in the passage

27、RT (总题数：2，分数：19.20)Reading 2 “Organic Architecture“One of the most striking personalities in the development of early-twentieth-century architecture was Frank Lloyd Wright (1867-1959). Wright attended the University of Wisconsin in Madison before moving to Chicago, where he eventually joined the fir

28、m headed by Louis Sullivan. Wright set out to create “architecture of democracy.“ Early influences were the volumetric shapes in a set of educational blocks the German educator Friedrich Froebel designed, the organic unity of a Japanese building Wright saw at the Columbian Exposition in Chicago in 1

29、893, and a Jeffersonian belief in individualism and populism. Always a believer in architecture as “natural“ and “organic,“ Wright saw it as serving free individuals who have the right to move within a “free“ space, envisioned as a nonsymmetrical design interacting spatially with its natural surroun

30、dings. He sought to develop an organic unity of planning, structure, materials, and site. Wright identified the principle of continuity as fundamental to understanding his view of organic unity: “Classic architecture was all fixation Now why not let walls, ceilings, floors become seen as component p

31、arts of each other? . This ideal, profound in its architectural implications. I called. continuity.“Wright manifested his vigorous originality early, and by 1900 he had arrived at a style entirely his own. In his work during the first decade of the twentieth century, his cross-axial plan and his fab

32、ric of continuous roof planes and screens defined a new domestic architecture. Wright fully expressed these elements and concepts in Robie House, built between 1907 and 1909. Like other buildings in the Chicago area he designed at about the same time, this was called a “prairie house.“ Wright concei

33、ved the long, sweeping ground-hugging lines, unconfined by abrupt wall limits, as reaching out toward and capturing the expansiveness of the Midwests great flatlands. Abandoning all symmetry, the architect eliminated a facade, extended the roofs far beyond the walls, and all but concealed the entran

34、ce. Wright filled the “wandering“ plan of the Robie House with intricately joined spaces (some large and open, others closed), grouped freely around a great central fireplace. (He believed strongly in the hearths age-old domestic significance.) Wright designed enclosed patios, overhanging roofs, and

35、 strip windows to provide unexpected light sources and glimpses of the outdoors as people move through the interior space. These elements, together with the open ground plan, create a sense of space-in-motion inside and out. He set masses and voids in equilibrium; the flow of interior space determin

36、ed the exterior wall placement. The exteriors sharp angular planes meet at apparently odd angles, matching the complex play of interior solids, which function not as inert containing surfaces but as elements equivalent in role to the designs spaces. （分数：8.84）(1).Frank Lloyd Wright took inspiration f
