Section C 26 International Womens Day(8 March)is an occasion marked by womens groups around the world. This date is also commemorated at the United Nations and is【 B1】_in m
16、any countries as a national holiday. When women on all continents, often divided by national boundaries and by【 B2】 _, linguistic(语言上的 )cultural, economic and political differences, come together to celebrate their Day, they can【 B3】_to a tradition that represents at least nine decades of struggle f
17、or equality,【 B4】_, peace and development. International Womens Day is the story of ordinary women as makers of history; it is rooted in the centuries-old struggle of women to【 B5】 _society on an equal footing with men. In ancient Greece, Lysistrata initiated a sexual strike against men in order to
18、end war; during the French Revolution, Parisian women【 B6】 _“liberty, equality, friendship“ marched on Versailles to demand womens rights to vote. The idea of an International Womens Day first arose at the turn of the century, which in the industrialized world was a period of【 B7】 _and turbulence, b
19、ooming population growth and radical ideologies. Since those early years, International Womens Day has assumed a new global dimension for women in developed and developing countries alike. The growing international womens movement, which has been【 B8】 _by four global United Nations womens conference
20、s, has helped make the commemoration a rallying point for【 B9】 _efforts to demand womens rights and participation in the political and economic process. Increasingly, International Womens Day is a time to reflect on progress made, to call for change and to celebrate acts of courage and determination

22、ull sense of the word, silent. From the very beginning, music was regarded as an【 C1】 _accompaniment; when the Lumiere films were shown at the first public film exhibition in the United States in February 1896, they were【 C2】 _by piano improvisations on popular tunes. At first, the music played【 C3】
23、 _no special relationship to the films; an accompaniment of any kind was【 C4】 _. Within a very short time, however, the incongruity(不协调 )of playing lively music to a【 C5】 _film became apparent, and film pianists began to take some care in【 C6】 _their pieces to the mood of the film. As movie theaters
24、 grew in number and importance, a violinist, and perhaps a cellist, would be added to the pianist in certain【 C7】 _, and in the larger movie theaters small orchestras were formed. For a number of years the selection of music for each film program【 C8】 _entirely in the hands of the conductor or leade
25、r of the orchestra, and very often the principal【 C9】 _for holding such a position was not skill or taste so much as the ownership of a large personal library of musical pieces. Since the conductor seldom saw the films until the night before they were to be shown(if indeed, the conductor was lucky e
26、nough to see them then), the musical arrangement was【 C10】_improvised in the greatest hurry.

It has been happening at a snails pace so far, but as it speeds up more and more low-lying coastal land will be lost. At risk are ma
28、ny of the worlds cities and huge areas of fertile farmland. The sea is set to rise a metre or more by the end of this century. And thats just the start. “Unless there is a rapid and dramatic about-face in emissions which no one expects the next century will be far worse than this century,“ says glac
29、iologist(冰川学家 )Bob Bindshadler of NASAs Goddard Space Flight Center, Maryland. B Throwing trillions of dollars at the problem could probably save big cities such as New York and London, but the task of defending all low-lying coastal areas and islands seems hopeless. Or is it? Could we find a way to
30、 slow the accelerating glaciers, drain seas into deserts or add more ice to the great ice caps of Greenland and Antarctica? C These ideas might sound crazy but we have got ourselves into such a bad situation that maybe we should start to consider them. If we carry on as we are, sea levels will rise
31、for millennia, probably by well over 10 metres. Slashing greenhouse gas emissions would slow the rise, but the longer we hesitate, the bigger the rise we will be committed to. Even if “conventional“ geo-engineering schemes for cooling the planet were put in place and worked as planned, they would ha
32、ve little effect on sea level over the next century unless combined with drastic emissions cuts. D In short, if coastal dwellers dont want their children and grandchildren to have to abandon land to the sea, now is the time to start coming up with Plan C. So New Scientist set out in search of the ha
33、ndful of researchers who have begun to think about specific ways to hold back the waters. E One of the reasons why the great ice sheets of Greenland and Antarctica are already shrinking is that the ice is draining off the land faster. Ice floating on the surrounding seas usually acts as a brake, hol
34、ding back glaciers on land, so as this ice is lost the glaciers flow faster. The acceleration of the Jakobshavn glacier in Greenland is thought to be the result of warm currents melting the floating tongue of the glacier. Other outlet glaciers are being attacked in a similar way. F Mike MacCracken o
35、f the Climate Institute in Washington DC is one of those starting to think that we shouldnt just sit back and let warm currents melt ice shelves. “Is there some way of doing something to stop that flow, or cool the water?“ he asks. G Last year, physicist Russel Seitz at Harvard University suggested
36、that the planet could be cooled by using fleets of customised boats to generate large numbers of tiny bubbles. This would whiten the surface of the oceans and so reflect more sunlight. MacCracken says the bubbles might be better arranged in a more focused way, to cool the currents that are undermini
37、ng the Jakobshavn glacier and others like it. A couple of degrees of chill would take this water down to freezing point, rendering it harmless. “At least that would slow the pace of change,“ MacCracken says. H What about a more direct approach: building a physical barrier to halt a glaciers flow int
38、o the sea by brute force? Bindshadler thinks that is a non-starter. “The ice discharge has many sources, mostly remote and in environments where barriers are not likely to work,“ he says. “Taking just the one example I know best, the Pine Island glacier in Antarctica drains into an ice shelf that at
39、 its front is 25 kilometres across and 500 metres thick, and moves at over 10 metres per day. The seabed there is 1000 metres down and is made of sediment(沉淀物 )hundreds of metres thick and the consistency of toothpaste.“ Not your ideal building site. I A slightly more subtle scheme to rein in the gl
40、aciers was proposed more than 20 years ago by Douglas MacAyeal of the University of Chicago. His idea is to fight ice with ice. The big outlet glaciers feed into giant floating shelves of ice, which break off into icebergs at their outer edges. MacAyeal suggested pumping water up from beneath the ic
41、e and depositing it on the upper surface, where it would freeze to form a thick ridge, weighing down the floating ice shelf. Add enough ice in this way, and the bottom of the ice shelf would eventually be forced down onto the seabed. Friction with the seabed would slow down the shelfs movement, whic
42、h in turn would hold back the glaciers feeding into it. It would be like tightening an immense valve. J “I think its quite an inspired idea,“ says Bindshadler. But nobody has followed it up to work out how practical the scheme would be. “On the back of an envelope it has promise but these ice shelve
43、s are big. You would need a lot of drilling equipment all over the ice shelf, and my intuition is that if you look at the energetics of it, it wont work,“ Bindshadler says. L Even if we could apply brakes to glaciers, this would only slow down sea level rise. Could we do better than that and reverse
44、 it actually make the sea retreat? If you think of the sea as a giant bathtub, then the most obvious way to lower its level is to take out the plug. M “One of the oldest notions is filling depressions on the land,“ says MacCracken. Among the largest of these is the Qattara depression in northern Egy
45、pt, which at its lowest point is more than 130 metres below sea level. Various schemes have been proposed to channel water from the Mediterranean into the depression to generate hydroelectric(水力的 )power, and as a by-product a few thousand cubic kilometres of the sea would be drained away. Unfortunat
46、ely, thats only enough to shave about 3 millimetres off sea level: a drop in the ocean. And there would be grave consequences for the local environment. “The leakage of salt water through fracture systems would add salt to aquifers(含水层 )for good,“ says Farouk El-Baz, a geologist at Boston University
47、 who has studied the region. N Refilling the Dead Sea is no better. Because of surrounding hills, this depression could be filled to 60 metres above sea level, but even that would only offset the rise by 5 millimetres and drown several towns into the bargain. O The notion of engineering lower sea le
48、vels remains a highly abstract topic. “If the world doesnt control emissions, Im pretty sure that no geo-engineering solution will work and it would potentially create other side effects and false promises,“ says MacCracken. “But if we do get on a path to curbing emissions dramatically down 50 per c
49、ent by 2050, say then the question becomes, can geo-engineering help with the hump were going to go through over the next few centuries?“ 47 Sea levels are rising very slowly at present. 48 Building physical barriers to keep glaciers may not be practical. 49 Filling depressions can only offset very little rise of sea levels. 50 One of the oldest ways to retreat the sea is to fill depressions on the land. 51 The ice fl
