One day, drought may be a thing of the
past, at least in any country not too far from the sea. Vast areas of desert
throughout the world may for the first time come to life and provide millions of
hectares of cultivated land where now nothing grows. By the end of this century this may not be mere speculation. Scientists are already looking into the possibility of using some of the available ice in the Arctic and Antarctic. In these regions there are vast ice-caps formed by snow that has fallen over the past 50,000 years. Layer upon layer of deep snow means that, when melted, the snow water would be pure, not salty as sea-ice would be. There is so much potential pure water here that it would need only a fraction to turn much of the desert or poorly irrigated parts of the world into rich farmland. And what useful packages would come in! It shou A. (A) The time for towing icebergs may be made shorter. B. (B) It is possible to use ships to tow icebergs from the polar areas. C. (C) Airline pilots may make use of jet streams to help tow an iceberg. D. (D) Not too much of the iceberg would melt while being towed through the oceans. [单项选择]根据《商业银行法》的规定,下列有关商业银行的表述,正确的是:

第一篇
A Sunshade(遮阳伞)for the Planet Even with the best will in the world,reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the most strong measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time,resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough. Fortunately,if the worst comes to the worst,scientists still have a few tricks up their sleeves. For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem. Until now,that is a growing number of researchers are taking a fresh look at large-scale"geoengineering"projects that might be used to counteract global warming."I use the analogy of methadone,"says Stephen Schneider,a climate researcher at Stanford University in California who was among the first to draw attention to global warming."If you have a heroin addict,the correct treatment is hospitalization,and a long rehab. But if they absolutely refuse,methadone is better than heroin." Basically the idea is to apply"sunscreen"to the whole planet. One astronomer has come up with a radical plan to cool Earth:launch trillions of feather-light discs into space,where they would form a vast cloud that would block the sun's rays.It's controversial,but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth's surface to counteract the warming produced by the greenhouse effect. Global climate models show that blocking just 1.8 percent of the incident energy in the sun's rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere.That could be crucial,because even the most severe emissions control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century,and that would last for at least a century more. What does Stephen Schneider say about a heroin addict and methadone? A.Methadone is an effective way to treat a hard heroin addict. B.Methadone is not a correct way to treat a heroin addict. C.Hospitalization together with methadone can work effectively with a heroin addict. D.Methadone and heroin are equally effective in treating a heroin addict. [单选题]支设高度在( )以上的柱模板, 四周应设斜撑, 并应设立操作平台。
