【2019·新课标】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 prent, the technologies are still expensive, though.
Rearchers 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 precily 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 curity by analyzing things like the force of a ur’s typing and the time between key press. The 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 us a keyboard and everybody types differently.
In a study describing the technology, the rearchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be ud to recognize different participants bad on how they typed, with very low error rates. The rearchers 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.
1．Why do the rearchers 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 e-space protection.苏炳添

2．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 curity measures are guaranteed.
3．What do the rearchers expect of the smart keyboard?
A．It’ll be environment-friendly. B．It’ll reach consumers soon.
C．It’ll be made of plastics. D．It’ll help speed up typing.
4．Where is this text most likely from?
收获的成语A．A diary. B．A guidebook. C．A novel. D．A magazine.
【答案】1-4 DCBD
【解析】这是一篇说明文。数据和身份盗窃变得越来越普遍，而指纹扫描等这些防盗技术仍然很昂贵的。本文介绍了一种新的防止个人身份和数据在电子空间被盗的高科技智能键盘，而且这项技术也不贵。中国十大军校排名
1．细节理解题。根据第一段的“At prent, the technologies are still expensive, though.”和第二段的“Rearchers from Georgia Tech say that they have come up with a low-cost device that gets around this problem: a smart keyboard.”可知，研究者们开发智能键盘是为了降低保护e-space的成本。故选D。
2．细节理解题。根据第二段的“The keyboard could offer a strong layer of curity by analyzing things like the force of a ur’s typing and the time between key press. The patterns are unique to each person. Thus, the keyboard can determine people’s identities”可知，每个用户打字的力度和按键间隔的时间是不同的，这使得智能键盘能够身份识别。故选C。渠道商
3．细节理解题。根据最后一段的“The team hopes to make it to market in the near future.”可知，研究者们希望智能键盘能早日面世。故选B。
4．推理判断题。本文介绍了一种新的防止个人身份和数据在电子空间被盗的高科技智能键盘，由此可推断本文最有可能来自于一本科学杂志。故选D。

【2019400字周记·新课标】Marian Bechtel sits at West Palm Beach’s Bar Louie counter by herlf, quietly reading her e-book as she waits for her salad. What is she reading? None of your business! Lunch is Bechtel’s “me” time. And like more Americans, she’s not alone.
A new report found 46 percent of meals are eaten alone in America. More than half (53 percent) have breakfast alone and nearly half (46 percent) have lunch by themlves. Only at dinnertime are we eating together anymore, 74 percent, according to statistics from the report.
如诗如画
“I prefer to go out and be out. Alone, but together, you know?” Bechtel said, looking up fro
m her book. Bechtel, who works in downtown West Palm Beach, has lunch with coworkers sometimes, but like many of us, too often works through lunch at her desk. A lunchtime escape allows her to keep a boss from tapping her on the shoulder. She returns to work feeling energized. “Today, I just wanted some time to mylf,” she said.
Just two ats over, Andrew Mazoleny, a local videographer, is finishing his lunch at the bar. He likes that he can sit and check his phone in peace or chat up the barkeeper with whom he’s on a first-name basis if he wants to have a little interaction(交流). “I reflect on how my day’s gone and think about the rest of the week,” he said. “It’s a chance for lf-reflection. You return to work recharged and with a plan.”

That freedom to choo is one reason more people like to eat alone. There was a time when people may have felt awkward about asking for a table for one, but tho days are over. Now, we have our smartphones to keep us company at the table. “It doesn’t feel as alone as it may have before all the advances in technology,” said Laurie Demeritt, who company provided the statistics for the report.
