问题                    Brave New World of Biometrics
    There are always people who can find a reason to criticize strongly any new technology as too personally invasive, but I’m all for biometrics. Among the amazing things biometrics enables us to do is to scan a person’s iris—the colored part of the eye—which displays a natural pattern that is even more distinct than the fingerprint.
    Imagine what that will do to cut down on credit card fraud if the pattern of a person’s iris must be scanned before the credit card can be used. Imagine how foolproof it will make Internet purchases, which are now extremely vulnerable to fraudulent abuse.      Biometrics’ ability to prevent theft against the government also is endless. When the state of Connecticut required people , to be fingerprinted in order to receive welfare benefits, 25 percent of the recipients dropped off the rolls ( many of whom, we have to assume, were receiving benefits improperly).
    Biometrics also will give Jaw-enforcement officers terrific new powers to track and capture international terrorists. Imagine what miniature face scans embedded secretly in passports will do to passport fraud, and the ability of terrorists to flee from one country to the next.
    Does this mean the government and corporations will have more "personal information" about you on file? Sure, to the extent that you consider your face or your iris to be personal "information". But all the hubbub about "invasion of privacy" is vastly overblown.
    Ever since the invention of telemarketing and the ceaseless parade of phone calls bombarding my home day and night began, I’ve considered my privacy to be a thing of the past. But in the scheme of things, it is a minor inconvenience, not a major assault.
    Of course, if biometrics is too much for some people, they always can cut up their credit cards, disconnect their phones and computers and move to the Rockies and live alone away from people and society. Meanwhile, I’ll continue to enjoy all the benefits modern technology offers.
According to the passage, biometrics_____’
选项 A、can make a recording of a person’s eye pattern by scanning his eyes
B、can provide a more accurate identification of a person by scanning his iris than the finger print recognition system
C、is a newly developed technology that can help analyze personal information
D、involves recognition techniques that are extremely sophisticated but very expensive
答案B
解析 本题是细节考查题。题目是：根据这篇文章，生物辨识系统______。第一段结尾提到：“Among the amazing things biometrics enables us to do is to scan a person’s iris______the colored part of the eye______which displays a natural pattern that is even more distinct than the fingerprint．”在生物辨识系统使我们能做到的诸多令人惊奇的事情中，扫描虹膜(眼睛中有颜色的部分)就是其中之一，虹膜展示出的天然图案要比指纹还独特。选项B，通过扫描人的虹膜的方法，能提供比指纹识别系统更准确的身份信息”，与原文意思相符，所以选B。
