Question

【题目】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 the number of your credit card 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.

The eye-recognition（眼睛识别）program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology will take the place of all other ways of finding out who people are.

Eye-recognition is a course of recognizing iris（虹膜）, which includes the following steps. First, a kind of machine needs to collect different examples of one’s iris from his eyes and store them. Second, when this person goes to the bank to take out money, this machine will have iris feature extraction（采集）. Then, this machine will compare the examples kept in it with iris feature extraction. Once the examples and the feature extraction are the same, this person will be identified, and he will take out the money from the bank successfully.

However, scientists are also 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 already have machines that can tell who you are from your voice or the mark made by your finger.

Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct now. In Britain, it was found that 91% of people who had tried it said that they liked the idea of

eye-recognition.

In the future your computer will be looking you in the eye. So smile!

Answer 1

【答案】

【1】C

【2】B

【3】C

【4】A

【5】C

【解析】试题分析：这篇短文主要介绍了一些用机器识别身份的方法，并且告诉我们将来会有更多的用机器识别身份的方法。

【1】C细节理解题，根据第二段开头的句子“The eye-recognition（眼睛识别）program has already been tested in shops and banks in the USA,Britain,Spain, Italy andTurkey.”可知，排除A. B. D。答案为C。

【2】B细节理解题，根据文章第三段，第一步是收集（collect）不同的视网膜作为参照，然后储存（store）；第二步是人到银行取款的时候，机器就会自动“特征提取（feature extraction）”；然后机器将会参照（example）与提取的视网膜特征（iris feature extraction）进行对比（compare），最后得出验证结果。答案为B。

【3】C细节理解题，根据短文倒数第二段中的句子“We already have machines that can tell who you are from your voice or the mark made by your finger.”可知，，目前已有的机器识别身份方式是声音和指纹验证。答案为C。

【4】A细节理解题，根据第四段介绍科学家正在研究新的身份验证方式；以及现有的身份验证方式，可知A选择符合题意。

【5】C细节判断题。根据短文最后一段中的句子“Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes.” 可知，每个人的眼睛都是不一样的A，all太绝对，且最后一段提到是在科技好的前提下才能达到94%；B，文中“91%of people who had tried it”，而选项中漏了“who had tried it”的信息；D，used to be(“曾经是”)表述有误，而文章最后一段是of the time(“目前”)，因此C项最佳。
