题文
US bees operation keeping groups have been attacked seriously by so called colony （群体）Collapse Disorder．Almost 1/2 of their worker bees have vanished during the past season．This disorder has also been reported in Israel, Europe and South America．Bees fly away from the hive and never return．Sometimes they are found dead; other times they are never found．Many crops and trees depend on pollination^^}） by bees to help them grow．A new report says a virus may be at least partly responsible for the disorder in honey bee colonies in the United States．This virus is called Israeli acute paralysis virus．It was first found in Israel in 2004．lan Lipkin at Columbia University in New York and a team reported the new findings in Science Magazine．Doctor Lipkin says the virus may not be the only cause．He says it may work with other causes to produce the collapse disorder．
The team found the virus in colonies with the help of a map of honey bee genes that was published last year．They examined thirty colonies affected by the disorder．They found evidence of the virus in twenty-five of them, and in one healthy colony．The next step is further testing of healthy hives．
The researchers suggested that the United States may have imported the disorder in bees from Australia．They say the bees may carry the virus but not be affected．
The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite．This insect attacks honey bees, which could make the disorder more likely to affect a hive．Australian bee producers object to these suspicions．
And some researchers suspect that bee production in the United States is down mainly because of the weather．Honey bees gather nectar from flowers and trees．The sweet liquid gives them food and material to make honey．But cold weather this spring in the Midwest reduced the flow of nectar in many flowers．Many bees may have starved．Dry weather in areas of the country could also be playing apart．
Wayne Esaias is a NASA space agency scientist who keeps bees in his free time．He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country.

解析
略考点
据考高分专家说，试题“US bees operation ke.....”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。
