　　专项提能计划——阅读理解（三） 科普类 (2011·高考陕西卷·D)Ever since they were first put on the market in the early 1990s，genetically modified (GM，转基因) foods have been increasingly developed and marketed in

　　many countries in the world，mainly on the basis of their promise to end the worldwide food crisis.But can GM technology solve world hunger problems? Even if it would，is it the best solution? Despite what it promises，GM technology actually has not increased the production potential (潜力) of any crop.In fact，studies show that the most widely grown GM crop，GM soybeans，has suffered reduced productivity.For instance，a report that analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production. Something else，however，has been on the rise.While GM seeds are expensive，GM companies tell farmers that they will make good profits by saving money on pesticides

　　(杀虫剂)．On the contrary，US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops.“The promise was that you could use less chemicals and boost production.But neither is true，” said Bill Christison，President of the US National Family Farm Coalition. At the same time，the authors of the book World Hunger：Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production，but by problems in food distribution and politics.These indeed deserve our efforts and money.Meanwhile，the rise in food prices results from the increased use of crops for fuel rather than food，according to a 2008 World Bank report. As a matter of fact，scientists see better ways to feed the world.Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger，because better ways out are available，among which “green” farming is supposed to be the first choice. 57．The author develops the second paragraph mainly________.

　　D．Casual. C 破题思路 本文对转基因食品展开了论述。转基因食品曾经被认为能够解决世界粮食危机，但现在看来，转基因食品非但没有解决预期的问题，却带来了诸多的问题，引发了更多的争议，那么解决世界粮食问题的出路在哪里呢？ 疑难剖析 Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger，because better ways out are available，among which “green” farming is supposed to be the first choice.(Paragraph 5) 该句为复合句，结构较为复杂。首先主句中使用了that引导的宾语从句，从句是一个because引导的原因状语从句，在原因状语从句中又使用了“介词among＋which”引导的定语从句。 句意：另一个世界银行的报告得出结 论认为转基因作物对于解决世界范围的贫穷和饥饿没有多大的帮助，因为还有更好的方法，其中绿色农业被认为是第一选择。

　　名师支招 了解文章结构、熟悉文章体裁、整合相关信息是提高考生阅读题目准确性的关键。 这篇文章属科普类文章，介绍了转基因农业的相关情况。文章第二段第一 句就表达了作者的基调——转基因农业没有增加农业产量。最后一段第一句说科学家找到了更好的方法来给人类提供食物。可见作者对转基因持不认可的态度，这样60题的答案就显而易见了。
