学案(三) 高考语篇的价值发掘——提升学科素养
2019·全国卷Ⅰ·阅读理解C篇——对接课标主题：科技发展与信息技术创新，科学精神，信息安全
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.
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. 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.
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, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
?好题不厌百回做，每做一次都有新发现

A．To reduce pressure on keys.
B．To improve accuracy in typing.
C．To replace the password system.
D．To cut the cost of e-space protection.
解析：细节理解题。根据第一段第二句可知，现有的生物测量技术价格昂贵；根据第二段的第一句可知，研究人员研发这种智能键盘是为了降低网络安全防护技术的成本，故选D项。

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。根据第二段的“These patterns are unique ...people's identities”可知，智能键盘能够准确地测量人们打字的节奏和力度，而这种模式因人而异，因此，智能键盘可以通过分析用户的打字模式进行身份识别，故选C项。
答案：C

2．(赏用词之美) This smart keyboard precisely measures the cadence with which one types and the pressure fingers apply to each key.
赏析：作者使用precisely measures (精确测量)，the cadence with which one types(打字的节奏)和the pressure fingers apply to each key(手指按压每个键的力度)等词和短语，通过“介词＋关系词”和“并列连词and”巧妙地组合在一个句子里，准确地说明了智能键盘的工作原理。
3．(赏意境之美)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.
赏析：作者运用offer, analyze等动词把一种可以通过分析用户的打字模式进行身份识别和提供一个强大的安全保护的智能键盘形象呈现在读者面前，用strong这个形容词表达了作者对于这种智能键盘的支持与肯定。
