Question

【題目】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（眼睛識別）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!

【解析】試題分析：這篇短文主要介紹了一些用機器識別身份的方法，并且告訴我們將來會有更多的用機器識別身份的方法。

【1】C細節(jié)理解題，根據(jù)第二段開頭的句子“The eye-recognition（眼睛識別）program has already been tested in shops and banks in the USA,Britain,Spain, Italy andTurkey.”可知，排除A. B. D。答案為C。

【2】B細節(jié)理解題，根據(jù)文章第三段，第一步是收集（collect）不同的視網(wǎng)膜作為參照，然后儲存（store）；第二步是人到銀行取款的時候，機器就會自動“特征提�。�feature extraction）”；然后機器將會參照（example）與提取的視網(wǎng)膜特征（iris feature extraction）進行對比（compare），最后得出驗證結(jié)果。答案為B。

【3】C細節(jié)理解題，根據(jù)短文倒數(shù)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，，目前已有的機器識別身份方式是聲音和指紋驗證。答案為C。

【4】A細節(jié)理解題，根據(jù)第四段介紹科學(xué)家正在研究新的身份驗證方式；以及現(xiàn)有的身份驗證方式，可知A選擇符合題意。

【5】C細節(jié)判斷題。根據(jù)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，每個人的眼睛都是不一樣的A，all太絕對，且最后一段提到是在科技好的前提下才能達到94%；B，文中“91%of people who had tried it”，而選項中漏了“who had tried it”的信息；D，used to be(“曾經(jīng)是”)表述有誤，而文章最后一段是of the time(“目前”)，因此C項最佳。
