Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help.
Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.
The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet.
The company also hopes to include other information on the chip, such as medical records, building security codes(密码) and passwords, making life even easier.
But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake(假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.
And if you wanted to get rid of your chip,you would need an operation to remove it.

题目分析：本文介绍了新型的产品芯片—它能置在人的胳膊上，来帮助顾客在购物时，可以根据特定的代码，顾客不用付费就从他们的账户中付账了。但是这难免有一些贼，用一些假的阅读器把顾客的信息盗走，从而在顾客不知情的情况下，把钱给偷走了，所以这就需要这种芯片做进一步的改善及提高。

点评：一个段落通常包含一个表达中心思想的主题句和若干与中心思想有关或为其提供论据的支持性句子。抓住段落的主题句是阅读理解的关键，主题句多位于段落的开头，有的在段中，有的在句尾，还有的主题句隐藏在段落的字里行间，需要学生自己总结和归纳。
