Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone's eyes are different．So in the future you won't have to remember a number when you want to use a machine or take money out of a bank．You'll just have to look at the machine and it will be able to tell who you are. This is eye-recognition program.
Meanwhile，scientists are working on other systems．Machines will soon be able to know you from the shape of your face or hand or even your smell! We have already had machines that can tell who you are from your voice or from your finger mark．
Eye-recognition is better than other kinds because your eyes don't change as you get older，or get dirty like hands or fingers．And even twins have different eyes，so the program can be up to 94% correct，depending on how good the technology is．Some programs may only be 51%．However, the correct rate(准确率) of eye-recognition grogram will be reduced in the dark.
The eye-recognition(眼睛识别) program is being tested in shops and banks in the U.S.A.，Britain，Spain，Italy and Turkey．In Britain，it was found that 91% of people who had tried it said that they liked the idea of recognizing(认出) you by your eyes．Soon this technology will take the place of all other ways of finding out who people are．

【主旨大意】本文为说明文。主要介绍眼睛识别系统的优点和缺点，将来它将会取代其他的识别系统。
1. C 细节理解题。从第一段的第四句“You'll just have to look at the machine and it will be able to tell who you are.”可知人们只要看一下机器,它就能判断你是谁,故选C。
2. B  细节理解题。从第二段的第四句“We have already had machines that can tell who you are from your voice or from your finger mark．”可知，现在已经有声音识别和指纹识别系统，故选B。
3. D  推理判断题。从第三段第四句“However, the correct rate(准确率) of eye-recognition grogram will be reduced in the dark.”可知眼睛识别系统在黑暗中将会降低准确率。由此判断眼睛识别系统在黑暗的房间里效果不太好，故选D。
4. A 细节理解题。从第三段第二句“the program can be up to 94% correct，”可知，眼睛识别系统能高达94%的准确率。
5. B 主旨大意题。通读全文可知，本文主要介绍眼睛识别技术，故选B。、
