The total U U 3 /U /Urainfall is spread pretty U U 4 /U /Uthroughout the year, and the tempe

Answer the questions below the text by choosing A, B, C or D.Warning on Global WarmingGlobal warming could cause drought and possibly famine in China, a new report predicts. Hong Kong could also be at risk fro

30、m flooding as sea levels rose. The report recommends building sea-walls around low-lying areas such as the new port and airport reclamations. Published by the World Wide Fund for Nature (WWF), the report, which includes work by members of the Chinese Academy of Meteorological Sciences, uses the most

31、 recent projections on climate change to point to a gloomy outlook for China.By 2050 about 30 to 40 percent of the country will experience changes in the type of vegetation it supports, with tropical and sub-tropical forest conditions shifting northward and hot desert conditions rising in the west w

32、here currently the desert is temperate. Crop-growing areas will expand but any benefit is expected to be negated by increased evaporation of moisture, making it too dry to grow crops such as rice. The growing season also is expected to alter, becoming shorter in southern and central China, the mainl

33、ands breadbasket. The rapid changes make it unlikely that plants could adapt.“China will produce smaller crops. In the central and northern areas, and the southern part, there will be decreased production because of water limitations,“ Dr. Rik Leemans, one of the authors of the report, said during a

34、 brief visit to the territory yesterday. Famine could result because of the demands of feeding the populationparticularly if it growsand the diminished productivity of the land. “It looks very difficult for the world as a whole,“ he said.Global warming is caused by the burning of large amounts of fo

35、ssil fuels, such as coal and oil, which release gases that trap heat in the atmosphere. World temperatures already have increased this century by about 0.6 degrees Celsius and are projected to rise by between 1.6 degrees and 3.8 degrees by 2100.Dr. Leemans said Chinas reliance on coal-fired power fo

36、r its industrial growth did not bode well for the world climate. “I think the economic power in China is much greater than the environmental power, and (greenhouse gas emissions) could accelerate,“ Dr. Leemans said. “China is not taking the problem seriously yet, although it is trying to incorporate

37、 this kind of research to see what is going to happen.“The climate change report, which will be released, focuses on China but Mr. David Melville of WWF-Hong Kong said some of the depressing scenarios could apply to the territory. Food supplies, for instance, could be affected by lower crop yields.

38、“Maybe we could afford to import food from elsewhere but you have to keep in mind that the type of changes experienced in southern China will take place elsewhere as well,“ he said. Sea levels could rise as glaciers melted and the higher temperatures expanded the size of the oceans, threatening much

39、 of developed Hong Kong which is built on reclaimed land. Current projections are that sea levels worldwide will rise by 15 to 90 centimetres by 2100, depending on whether action is taken to reduce greenhouse gas emissions.“Hong Kong has Usubstantial/U areas built on reclaimed land and sea level ris

40、es could impact on that, not only on Chek Lap Kok but the West Kowloon Reclamation and the Central and Western Reclamationthe whole lot,“ Mr. Melville said, adding that sea-walls would be needed. Depleted fresh water supplies would be another problem because increased evaporation would reduce levels

41、. Mr. Melville said the general outlook could be helped if Hong Kong used water less wastefully and encouraged energy efficiency to reduce fuel-burning. He also called on the West to help China improve its efficiency.（分数：10.00）(1).What is the overall situation of the future effects of global warming
