题文
阅读理解。 Everywhere you look, large quantities of information in the world are pouring. This data flood isalready starting to transform business, government, science and everyday life. It has great potential for
good - aslong as consumers, companies and governments make the right choices about when to restrict
the flow ofdata, and when to encourage it.
A few industries have led the way in their ability to gather and take advantage of the data.
Credit-cardcompanies monitor every purchase and can identify cheats with a high degree of accuracy.
Stolen credit cards are more likely to be used to buy hard liquor than wine, for example, because it is
easier to overlook. Insurance firms are also good at combining clues to spot doubtful claims: dishonest
claims are more likely to be made on a Monday than a Tuesday, since policyholders (保险客户) who
stage accidents tend to assemble friends as false witnesses over the weekend. By combining many such
rules, it is possible to work out which cards are likeliest to have been stolen, and which claims are
untrue. By analyzing "basket data", supermarkets can make promotions to appeal to particular
customers' preferences. The oil industry uses supercomputers to help them before drilling wells.
But the data flood also poses risks. There are many examples of databases being stolen: disks
full of social-security data go missing, laptops loaded with tax records are left in taxis, credit-card
numbers are stolen by online purchase. The result can be privacy made public, identity stolen and
cheats permitted large space. Rather than owning and controlling their own personal data, they very
often find that they have lost control of it.
The best way to deal with the data flood is to make more data available in the right way, by requiring
greater transparency in several areas. First, users should be given greater access to and control over the
information held about them, including whom it is shared with. Google allows users to see what information
it holds about them, and lets them delete their search histories or modify the targeting of advertising, for
example. Second, organizations should be required to disclose details of security breaches, as is already
the case in some parts of the world, to encourage bosses to take information security more seriously.
Third, organizations should be subject to an annual security check, with the resulting grade made public
(though details of any problems exposed would not be). This would encourage companies to keep their
security measures up to date.1. What is the best title for this passage?A. Information Flood

考点
据考高分专家说，试题“阅读理解。 Ever.....”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。
