Question

【题目】 Imagine you're standing in line to buy an afterschool snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR code with your smartphone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.

【1】 As technology companies move away from traditional password, biometric(生物识别) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

In 2013, Apple introduced the iPhone 5s, one of the first smartphones with a fingerprint scanner. Since then, using one’s fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since last year, Samsung has featured eye-scanning technology in its top smartphones, while Apple’s new iPhone X can even scan a user’s face.

【2】 “Biometrics, ideally, are good,” John Michener, a biometric expert, told tech website Inverse. “In practice, not so much.”

When introducing the new iPhone’s Face ID feature at Apple’s Keynote Event in September, Phil Schiller, Apple’s senior vice president, said, “【3】”

But it’s already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. And they aren’t even twins.

“We may expect too much from biometrics,” Anil Jain, a computer science professor at Michigan State University, told CBS news. “No security systems are perfect.”

Earlier this year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smartphone for police.

“It’s good to see biometrics being used more,” Jain told CBS News, “because it adds another factor for security. 【4】”

A. But despite its popularity, experts warn that biometrics might not be as secure as we’d imagined.

B. Security experts don’t think it absolutely necessary to use biometric technology.

C. But using multiple security measures is the best defense.

D. Now, this type of technology might not be far away.

E. If a person’s biometric information is stolen, that could have extremely serious consequences for that individual

F. The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million.

Answer 1

【答案】

【1】D

【2】A

【3】F

【4】C

【解析】

这是一篇说明文。本文介绍了关于生物识别技术一些东西，一些人认为更多的使用生物识别全技术是好的，因为它为我们的生活提供了一道安全屏障，但使用多个安全措施是最好的防御。

【1】根据下文As technology companies move away from traditional password, biometric security, which includes fingerprint, face and voice ID, is becoming increasingly popular.（随着科技公司逐渐抛弃传统密码，包括指纹、人脸和语音识别在内的生物识别安全技术正变得越来越受欢迎。）可知随着科技的发达，上文所提到的技术离人们已经并不遥远了。故D项：Now，this type of technology might not be far away．现在，这种技术可能并不遥远。符合语境。故选D。

【2】根据后文“Biometrics, ideally, are good,” John Michener, a biometric expert, told tech website Inverse. “In practice, not so much.”（“理想情况下，生物识别技术是好的，”生物识别专家约翰·麦切纳(John Michener)告诉科技网站reverse。“实际上，没有那么好。”）可知理想情况下，生物识别技术是好的。但是也并没有人们想象的那么好。故可推测本空是在说明生物技术存在的问题。故A项：But despite its popularity，experts warn that biometrics might not be as secure as we'd imagined．但专家们警告说，尽管生物识别技术很受欢迎，但它可能不像我们想象的那么安全。符合语境。故选A。

【3】根据上文提到了新iPhone的人脸身份识别功能。结合下文But it’s already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. And they aren’t even twins.（但已经有人这么做了。据Quartz网站报道，11月3日，在社区网站Reddit上发布的一段视频中，两兄弟展示了他们如何用自己的脸解锁同一款iPhone X。他们甚至不是双胞胎。）可推知苹果高级副总裁菲尔·席勒在绍新款iPhone的面部识别功能时，认为苹果手机不可能被随便任何人解锁。而下文推翻了他的说法，but表示转折。故F项：The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million．随便一个人看到你的iPhone X，然后用他的脸解锁的几率大约是百万分之一。符合语境。故选F。

【4】根据前文"It's good to see biometrics being used more，"Jain told CBS News，"because it adds another factor for security．（“很高兴看到生物识别技术得到更多的应用，”Jain告诉CBS新闻，“因为它增加了另一个安全因素。）中security可对应到C项中security measures。表示：但使用多个安全措施是最好的防御。符合语境。故选C。
