Iris recognition is giving a new "look" to personal identity.See this cutting-edge science.Then try it yourself!
Nick D'Alto
How can you tell an ordinary airline passenger from an international spy?Or an everyday banking customer from a dangerous cyber-hacker?That's easy.Just look into their eyes using a new identity technology called iris recognition.
This high-tech identity tool can help officials spot a wanted criminal at an airport,or recognize you at a bank's ATM terminal.How is it done?By examining the complex patterns in the human eyes.That's the pigmented ring between your sclera (the white of your eye) and the pupil (the dark centre).In other words,the part of your eye that is brown,or hazel,or blue.
You Have Your Mother's Eyes
Not really!The patterns that make up your irises are different from those of everyone else in your family,and also from those of every other person in the world.Fingerprints are also unique,but irises contain more information than fingerprints — there are more patterns and variations for a biometric scanner to pick up.Scientists call both fingerprints and iris patterns epigenetic (not determined by genetics).That's what makes them so varied — and so good for verifying your identity.Even identical twins don't have exactly the same fingerprints,or the same iris patterns.
Your Own "You-nique" Irises
Examine your eyes closely in a mirror (a magnifying mirror works best).Those many different-shaped dark flecks around your iris all have names.Scientists call them rifts,pits,freckles,crypts,and coronas.At a microscopic scale,smooth,shiny irises become jagged mountain ranges of "contractive furrows" and "serpentine vasculatures." Those are just fancy names for your unique eye patterns.
Your iris patterns remain unchanged throughout your life.In fact,they virtually cannot be altered.Also squinting,contact lenses,or other simple tricks can't fool a state-of-the-art iris scanner.
Iris scans also work in a fraction of the time required for fingerprint matching,voice printing,or other biometric measurements.
They're already used in highly secure workplaces.Instead of using traditional identity methods,like ID cards or PIN numbers,at these places all you need is your eyes.Some schools scan their students' irises for security records,and at many of the world's airports your eyes are even better proof of identity than your passport.Soon,you might make a credit card purchase,have a prescription filled,or log onto a computer,just by looking in the right direction!
1.Determine whether the following statement is true.
The pigmented part of a person's eye is known as the sclera.
A.The statement is true according to the passage.
B.The statement is contradictory to information given in the passage.
C.The required information is not given directly nor can be reasonably deduced from the passage.
2.What is implied in the third paragraph of the article?
A.The only people in the world who have the exact same fingerprints are twins.
B.A person's iris has more patterns and variations than his or her fingerprints do.
C.A person's fingerprints and iris patterns are determined by genetics only.
D.Iris patterns cannot be used to identify a person's true identity.

第一题答案为B
第二题答案为B
具体解释：
B. The statement is contradictory to information given in the passage.
因为在第三段中有一句话
That's the pigmented ring between your sclera (the white of your eye) and ...
这句话已经指出了pigmented ring（即pigmented part）是介于眼白和...之间的部分.
所以The pigmented part of a person's eye is known as the sclera有颜色的部分就是眼白的这一陈述就和以给的信息相矛盾了.
所以第一题答案为B
B. A person's iris has more patterns and variations than his or her fingerprints do.
这道题相对简单些,第三段中已经明确给出了内容Fingerprints are also unique,irises contain more information than fingerprints. there are more patterns and variations for a biometric scanner to pick up.
其它三个答案错的就太明显了
所以第二题答案为B

虹膜识别是一种新的“看”到个人的身份。看到这个尖端的科学。然后试一试吧!
尼克·D 'Alto
你怎么说一个普通的航空乘客从国际间谍?或者是每天从一个危险的cyber-hacker银行业客户?那很容易。只是看着他们的眼睛使用一种新身份的身份识别技术。
这个高科技的身份工具可以帮助官员发现一犯罪在机场或认出你到银行的自动取款机终端。它是如何呢?通过复杂的模式,在人类的眼睛。那是你的着色环之间的白色巩膜(眼睛)和学生(黑暗的中心)。换句话说,你的眼睛的一部分是棕色的,或浅褐色或蓝色
你有你的母亲的眼睛
不是真的!这个模式让你的虹膜有别于其他人都在你的家庭,并与其他所有人在世界上的更大。指纹是独特的,但是也包含了更多的信息,虹膜比指纹-有更多的模式和变化对于一个生物扫描器捡来的。科学家们称双方的指纹和虹膜模式遗传(不是由基因决定的)。那是什么使他们如此多样,所以适合核实身份。即使同卵双胞胎没有完全相同的指纹、或相同的虹膜的模式。
你自己的“You-nique”的虹膜
检查你的眼睛在镜子(一面放大镜-最佳作品)。许多different-shaped暗斑点围绕着你的虹膜都有名字。科学家称之为裂缝、凹坑、雀斑,当然唱。在微观尺度、光滑、闪亮的虹膜参差不齐的山脉,成为“收缩犁沟”和“一条龙的vasculatures。”这些只是喜欢的名字为你的模式。
你的虹膜模式你终生不变。事实上,他们几乎无法改变。也借着,隐形眼镜,或其它简单的诡计骗不了先进的虹膜扫描器
虹膜扫描工作也在一小部分所需的时间相匹配的声音、印刷、指纹或其他生物的测量方法
他们已经习惯在高度安全的工作场所。与其使用传统的身份的方法,如身分证或密码,在这些地方,所有你所需要的是你的眼睛。有些学校学生的虹膜扫描记录,并对安全的世界上的许多机场你的眼睛是更好的身份证明比你的护照。在不久的将来,你可能犯信用卡购买,有一个处方药,或登录电脑,只要看看在正确的方向上!
从法兰克福机场到伦敦去东京已使用虹膜扫描使旅行快,更安全、更方便为外国游客。乘客就读于特殊iris-passport系统,例如詹姆斯Wayman只需站在一个扫描器收到登记服务,避免长时间地在海关。纽约肯尼迪机场使用虹膜扫描确认身份的飞行员和船员。很多终端使用它们来限制进入敏感地区的机场。在阿拉伯联合酋长国,虹膜扫描仪进行超过4亿眼(问题)来防止每天的确是的爱好艺术的确是的人驱逐出境永不回来。你能想象另一个身份的方法,可以这样做吗?“眼球”不能!
