Some people in Manchester, Britain, will soon be paying for goods and services with so-called “smart” credit cards. These cards are more secure than the traditional magnetic-strip version and can be used to travel on buses, check bank accounts and do shopping.
The Manchester project is one of the biggest smart card schemes in the world. Every time people use the cards on a bus or train, the fare is deducted (reduced) from the value of the card. When they have no credit left, the cards can be recharged at a local shop.
Information is transferred by running the card through a narrow opening in an electronic reader. In the slot, electronic probes make contact with the magnetic-strip or silicon ship and read the information. The other type is the contactless smart card where the electronic reader communicates with the card by short-range radio waves. This makes the card quicker and more convenient to use because it does not have to leave your wallet. It is also more reliable as it is not easily influenced by scratches or dirt. However, the biggest advantage that smart cards have over magnetic-strip cards is that they are more secure. They are much more difficult to make than conventional cards and they have to be made by specially trained manufacturers. In addition, they have a large number of extra security features on them and if a smart card gets lost or stolen a quick phone-call to the distributor ensures that its individual number is made invalid and unreadable. This can be done more quickly than with a magnetic-strip card.

◎ 政治经济类阅读的知识点拨
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。
