Often, however, it is presented to us as being so abstract that it seems impossibly distant. For those of you looking for something a little more concrete, a new report suggests that the effects of climate change may significantly affect coffee. The report, put out by The Climate Institute, describes the effects of climate change on various coffeegrowing nations and the resultant effects on the plants and those who grow them. Coffee Arabica plants, which produce 70% of all mercial coffee, can be adversely affected by even a halfdegree change in typical weather conditions. This sensitivity to temperature puts the plant at increased risk of the effects of climate change. In Central America the average temperature has risen by a full degree Celsius since 1960. In Ethiopia the average temperature has increased by 1. 3 degrees. This increase is enough to have notable effects on the plants. In Tanzania the productivity per hectare of coffee has fallen by half since the 1960s due to changes in temperature. Indeed, studies claim that by 2050 the area of the world suitable for growing coffee will be cut by half. Coffee production is likely to then be pushed to higher elevations (海拔) to take advantage of lower temperatures, but this will not be enough to make up for lost lowland areas. Coffee is the second most traded goods by developing nations, and the inability of producer nations to export it could cause dramatic chain reactions in their economies. Millions of people make a living in the production, processing, transport, and sale of coffee。 their livelihoods would stand to take a blow as growing areas decrease and prices rise. As the temperature keeps rising, your cup of coffee will bee much more expensive, and it may also carry an aftertaste bitterer than usual, for all those workers in the coffee belt left without the means to make a living as conditions worsen. Not only that, but the economic effects will cost the West millions in increased foreign aid.（1）What does the underlined word adversely in Paragraph 3 most probably mean?

A.To adapt to the change of temperature.B.To increase the quality of the products.C.To reduce the cost of coffee productionD.To get access to water supply more easily.（3）What conclusion can we draw from the last two paragraphs? A.The rich will get richer and the poor poorer.B.Small changes may have large effects in general.C.Developed countries ought to aid poor countries.D.Coffee trade will eventually disappear in the world.（4）How does the author feel about the future of coffee production? A.Cautious.B.Worried.C.Unconcerned.D.Hopeful.【答案】 （1）C（2）A（3）B（4）B 【解析】【分析】本文是一篇說明文，一份新的報(bào)告表明，氣候變化的影響可能會顯著影響咖啡。到2050年，世界上適合種植咖啡的面積將減少一半?？Х犬a(chǎn)業(yè)的變化會對社會造成很多影響。 （1）考查詞義猜測。根據(jù)第三段中的“This sensitivity to temperature puts the plant at increased risk of the effects of climate change.”這種對溫度的敏感性增加了植物受到氣候變化影響的風(fēng)險(xiǎn)。由此推斷出，上文的意思是阿拉比卡咖啡的產(chǎn)量占所有商業(yè)咖啡的70%，在典型的天氣條件下，即使氣溫只上升了半度，也會對其產(chǎn)生不利影響。adversely意思是有害的，故選C。 （2）考查推理判斷。根據(jù)第五段中的“Coffee production is likely to then be pushed to higher elevations to take advantage of lower temperatures, but this will not be enough to make up for lost lowland areas.”咖啡生產(chǎn)很可能會被推到更高的海拔，以利用更低的溫度，但這將不足以彌補(bǔ)失去的低地地區(qū)。由此推斷出，人們要在高地地區(qū)種植咖啡是為了適應(yīng)溫度的變化，故選A。 （3）考查推理判斷。根據(jù)倒數(shù)第二段中的“Coffee is the second most traded goods by developing nations, and the inability of producer nations to export it could cause dramatic chain reactions in their economies.”咖啡是發(fā)展中國家的第二大貿(mào)易商品，而生產(chǎn)國無法出口咖啡，可能會在其經(jīng)濟(jì)中引發(fā)巨大的連鎖反應(yīng))和最后一段中的“Not only that, but the economic effec
