题文
Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no.“We don’t know whether the food is safe,” said Zambia’s commerce, Trade and Industry Minister Dipak Patel.
His worries are shared by countries around the world that are in two minds about America’s genetically modified（GM,转基因的）crops．Just last week, EU（欧盟）member nations were discussing whether or not to import GM sweet corn from the US．
Ever since people started farming, they have tried to crossbreed（杂交）plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other．
But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.
This means they can make crops more productive and resistant to disease by adding genes from other species．They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.
At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.
Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops．
People in China are also getting worried about GM foods. More than 70 percent of the
country’s soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them.

答案
小题1:C
小题2:B
小题3:D
小题4:D
小题5:B
解析
文章大意：每年有数百万非洲人死于饥饿，但是赞比亚拒绝了美国无偿赞助的玉米，这是为什么呢？原来那是美国生产的转基因食品，世界上有很多人对这种食品持怀疑态度。
小题1:C主旨大意题。根据第一段并浏览全文不难看出本文的中心是在讲转基因食品，但并没有证据证明转基因食品的确危害人的健康。作者也只是客观地陈述人们和各个国家的态度和看法。所以选择C、“转基因食品，对健康有危害吗？”。
小题2:B 细节推断题。 根据文章第二段答语，“We don’t know whether the food is safe,”推断赞比亚政府关心转基因食品的安全问题。
小题3:D 细节推断题。根据第二段内容when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.及第三段内容 This means they can make crops more productive and resistant to disease by adding genes from other species．推断出转基因技术能够增产已经被证明。所以选择D。根据第四段内容可知，争议说“转基因食品对人类不可能有危害，”但人们依然质疑一些有关问题，所以A项说，转基因食品对人体有害，这一点并没有得到充足证明，所以选项错误。
小题4:D 细节理解题。根据文章倒数第二段Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies.一些专家相信加入到农作物中的转基因物质会渗入人体，对我们的身体造成危害，所以答案选D。
小题5:B 作者意图题。纵观全文，作者只是客观地叙述了很多人和国家的态度和看法，自己并没有发表任何见解，故应该是持中立的态度(neutral)。A 支持的；C怀疑的；D批判的，所以答案选B。
考点
据考高分专家说，试题“Millions of people d.....”主要考查你对 [政治经济类阅读 ]考点的理解。政治经济类阅读
政治经济类文章的概念：
要做好这类阅读，平时就要注意了解国内外发生的政治经济大事，掌握一定背景知识，对这类文章的叙述特点及内容安排有一定了解，还要扩展这方面的词汇。阅读这类文章，要抓住文章的核心，即文章整体和各段主要在说什么，也要注意段落之间的逻辑关系。
如何备考政治经济类阅读理解题：
【题型说明】政治经济类阅读文章是高考常选材料之一。该类文章时代气息浓郁，语言鲜活，但熟字新义词、超纲词及专业词语多，长句、难句多。政治类文章大多数是同学们感性趣的内容，读起来倒有似曾相识的感觉，经济类文章读起来就像是雾里看花，文章看完，一头雾水。再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨，同学们对这类题材是望而生畏。
【备考策略】建立心理优势。针对不同体裁的文章，我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式，我们可采取“顺读法”，以便抓关键语句，领会文章主旨；而经济类文章则多采用说明文形式，我们则可以采取“逆读法”，先读试题，再从文章中查找有用信息。若遇到的确难读的材料。千万不用着急，因为你觉得难，其他人也一定是同感。在高考前，我们就要有这种心理准备，高考试卷肯定有一、两篇难以阅读的材料。不过，我们平时可以有意识地从报刊杂志上找一些较难的阅读材料来阅读，以培养自己迎难而上的心理素质。
【答题方法】
1、寻找主干：
根据英语中五种基本句型结构，把句子中的主语、谓语、宾语、表语等主要成分找出来，其他成分如定语、状语、补语等则易于理解。找到了句子主干，句子的意思至少明白了一半。
2、剔除从句：
在一个长句中可能会出现若干个从句，在理解时，如果把各个从句剔除出来单独理解，然后把大意拼凑起来，整个长句的意思就会明白六、七分。
3、辨别分句：
一个长句如果是由几个并列、转折、递进、对比关系的分句组成，句中往往有表示这些分句关系的连接词，只要能弄清楚分句和分句之间的逻辑关系，再把各层分句的意思加以连贯，整个长句的句意基本上能跃然脑中。
4、寻找关键词：
如果一个句子看完，一点句意的感觉也没有，下下策就是抓住句中的关键词，通过关键词大体弄懂这个长句的意思。
