fingerprint(commercialize)

层次与结构分析:第一段一般是introduction,介绍本文基本背景→网络安全相关问题

As data and identity theft becomes more and more common, the market is growing for biometric(生物测量)technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

数据和身份盗窃变得越来越普遍,生物测量技术在增长,如指纹扫描,不让其他人进入私人网络空间。然而,目前这些技术仍然很昂贵。

层次与结构分析:阐述本文主旨

Researchers from Georgia Tech say that they have come up with a low-cost device(装置)that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏)with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. (上述三句话即为第2题答案直接来源)Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to — regardless of whether someone gets the password right.

佐治亚理工学院的研究人员说,他们已经提出了一种低成本的设备::智能键盘。这个智能键盘精确测量哪一个手指的节奏,适用于每个键类型和压力。通过分析用户打字的力度和按键之间的间隔时间,键盘可以提供一个强大的安全层。这些模式对每个人来说都是独一无二的。因此,键盘可以确定用户的身份,进而决定用户是否有权访问与其相连的计算机,而不管用户的密码是否正确。

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

它也不需要一种人们不熟悉的新技术。每个人都使用键盘,每个人的打字方式也不同。

In a study describing the technology, the researchers had 100 volunteers type the word "touch"four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straight forward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future. (后两句话为第三题答案直接来源)

在一项描述这项技术的研究中,研究人员让100名志愿者用智能键盘四次输入“触摸”这个词。从设备上收集的数据可以根据不同参与者的打字方式来识别他们,错误率非常低。研究人员说,键盘应该是相当直接的商业化,它主要由廉价的塑零件构成。该团队希望在不久的将来将其推向市场。

28. Why do the researchers develop the smart keyboard?

A. To reduce pressure on keys(偏离主旨). B. To improve accuracy in typing(偏离主旨)

C. To replace the password system . D. To cut the cost of e-space protection.

降低电子空间保护成本。

答案解析:基本理解第一段大意即可答对题目,选择D

29. What makes the invention of the smart keyboard possible?

A. Computers are much easier to operate.

B. Fingerprint scanning techniques develop fast.

C. Typing patterns vary from person to person.

D. Data security measures are guaranteed.(排除项)

答案解析:C选项来自第二段的前半部分:a low-cost device(装置)that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏)with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person。主要含义:每个人触摸键盘的力度和模式都是独一无二的,可以用作网络安全保护措施,与C选项为同义句。

30. What do the researchers expect of the smart keyboard?

A. It’ll be environment-friendly.(偏离主旨)B. It’ll reach consumers soon.

C. It’ll be made of plastics. (偏离主旨)D. It’ll help speed up typing.(偏离主旨)

答案解析:用排除法可高效答对题目(前提理解本文主旨,因为错误选项普遍远离主旨)

31. Where is this text most likely from?

A. A diary. B. A guidebook C. A novel. D. A magazine.
