话题：智能键盘 词数：255 难度：★★★

As data and identity theft bees more and more mon，the market is growing

for biometric (生物测量) technologies—like fingerprint scans—to keep others out of

private e­spaces.At present，these technologies are still expensive，though.

Researchers from Georgia Tech say that they have e up with a low­cost

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.Thus，the keyboard can determine people's

identities，and by extension，whether they should be given access to the puter it's

connected to—regardless of whether someone gets the password right.

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.

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，优选

- 2 - / 17 with very low error rates.The researchers say that the keyboard should be pretty

straightforward to mercialize and is mostly made of inexpensive，plastic­like parts.The

team hopes to make it to market in the near future.

[语篇解读] 本文是一篇科研报道。来自佐治亚理工学院的研究人员发明了一种智能键盘，可以通过分析用户的打字模式来判断该用户是不是安全访客。

28．Why do the researchers develop the smart keyboard?

A．To reduce pressure on keys. B．To improve accuracy in typing.

C．To replace the password system.D．To cut the cost of e­space protection.

解析：推理判断题。根据第一段最后一句“At present，these technologies are still

expensive，though.”以及第二段第一句“Researchers from Georgia Tech say that they

have e up with a low­cost device that gets around this problem: a smart keyboard.”可推知，研究者研发这种智能键盘是为了降低网络安全保护技术的成本。注意题干、正确选项以及原文中一些词汇的多次呼应现象：develop与e up with是同义词，expensive与low­cost是反义词，cut the cost与low­cost相呼应。

答案：D

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

A．puters 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.

解析：推理判断题。题干问的是“是什么让智能键盘的发明成为可能”，也就是问这一发明的核心依据是什么。根据第二段中的“These patterns are unique to each

person.Thus，the keyboard can determine people's identities...”可知，正是因为每个人的打字模式不同，这种智能键盘就可以通过分析用户的打字力度及节奏等来判断该用户是不是安全访客，故C项符合题意。

答案：C 优选

- 3 - / 17 30．What do the researchers expect of the smart keyboard?

A．It'll be environment­friendly.B．It'll reach consumers soon.

C．It'll be made of plastics.D．It'll help speed up typing.

解析：细节理解题。根据题干“研究者对于智能键盘有什么期望”可直接定位到最后一段的最后一句话“The team hopes to make it to market in the near future.(该团队希望在不久的将来将智能键盘推向市场)”，故选B项。注意：题干中的expect与原文中的hope呼应，答案选项中的consumers与原文中的market呼应。

答案：B

31．Where is this text most likely from?

A．A diary.B．A guidebook.

C．A novel.D．A magazine.

解析：文章出处题。根据本文的话题“智能键盘”以及第二段中的“Researchers from

Georgia Tech say that they have e up with a low­cost device...”，尤其是其中的关键词researchers，low­cost device等来推断，这篇文章是一篇科研报道，最有可能出现在杂志上。

答案：D

一、语言能力

熟词生义/ 词类活用

1．get around 克服，解决

2．apply to 施加

3．access n．权利

4．make it to 赶上，成功到达

二、思维品质

1．阅读技巧——文章出处题

此类试题考查对文章体裁以及文章的出处进行合理判断的能力。如第31题。常见设问方式： 优选

- 4 - / 17 (1)This passage can be classified as .

(2)The text is most probably a .

(3)Where does the text probably e from?

(4)Where can you find this passage?

常见文章出处：①newspaper (报纸) ②advertisement(广告) ③instructions(说明书)

④website() ⑤magazine (杂志) ⑥report (报告)

⑦diary (日记) ⑧guide (导游手册)

2．分析长难句并翻译句子

Researchers from Georgia Tech say that they have e up with a low­cost device

that gets around this problem: a smart keyboard.

[分析]这是一个复合句，第一个that引导宾语从句，第二个that引导限制性定语从句，修饰device。

[翻译]来自佐治亚理工学院的研究人员说，他们已经想出了一种低成本的能解决这个问题的设备：智能键盘。

三、文化素养

思考：通过阅读这篇文章，你认为作为中学生，我们应如何为科技的发展做出自己的贡献？

我们要不断提高自身的思想道德修养，与同学互相帮助，尊师重道，团结友爱，积极参加学院和学校组织的各项活动，不断提高自身的社会知识，努力学习科学文化知识，重视专业知识与实践经验相结合。
