At present, these technologies are still expensive, though. Researchers from Georgia Tech say that they have come 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 users typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine peoples identities, and by extension, whether they should be given access to the computer its connected toregardless of whether someone gets the password right. It also doesnt require a new type of technology that people arent 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, plasticlike parts. The team hopes to make it to market in the near future. 【解题导语】本文是一篇说明文，主要向我们介绍了一种防止个人身份和数据在电子空间被盗的高科技智能键盘。1Why do the researchers develop the smart keyboard?ATo reduce pressure on keys. BTo improve accuracy in typing. CTo replace the password system. DTo cut the cost of espace protection. 解析：选D细节理解题。根据第一段最后一句“At present, these technologies are still expensive, though. ”和第二段第一句“.they have come up with a lowcost device that gets around this problem”可知，研发智能键盘的目的是为了降低保护电子空间的成本。2What makes the invention of the smart keyboard possible? AComputers are much easier to operate. BFingerprint scanning techniques develop fast. CTyping patterns vary from person to person. DData security measures are guaranteed. 解析：选C细节理解题。根据第三段中的“Everybody uses a keyboard and everybody types differently. ”可知，人与人打字的模式不同，使得这一发明能够实现其功能。3What do the researchers expect of the smart keyboard?AItll be environmentfriendly. BItll reach consumers soon. CItll be made of plastics. DItll help speed up typing. 解析：选B细节理解题。根据最后一段中的“.the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plasticlike parts. The team hopes to make it to market in the near future. ”可知，实现智能键盘商业化很容易，并且其造价并不昂贵，因此研发团队希望在不久的将来能将其投放市场。4Where is this text most likely from?AA diary. BA guidebook. CA novel. DA magazine. 解析：选D推理判断题。本文是一篇说明文，主要介绍了一种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刊登在 (科学) 杂志上。. 完形填空(2019全国卷)The small town of Rjukan in Norway is situated between several mountains and does not get direct sunlight from late September to midMarch 1 six months out of the year. “Of course, we 2 it when the sun is shining，” says Karin Ro, who works for the towns tourism office. “We see the sky is 3 , but down in the valley its darkerits like on a 4 day. ”But that 5 when a system of hightech 6 was introduced to reflect sunlight from neighboring peaks (山峰) into the valley below.
