1. 电脑网线【2019·全国卷I，C】
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(装置微信营销策略)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 perso
n. 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.
28. Why do the rearchers develop the smart keyboard?
A. To reduce pressure on keys. B. To improve accuracy in typing
骆驼祥子经典语录C. To replace the password system. D. To cut the cost of e-space protection.
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 curity measures are guaranteed.
30. What do the rearchers expect of the smart keyboard？all 1o soisgitieoco oll.热身动作
A. It'll be environment-friendly. B. It'll reach consumers soon.

2. 【2019·全国卷I，D】
During the rosy years of elementary school(小学), I enjoyed sharing my dolls and jokes, which allowed me to keep my high social status. I was the queen of the playground. Then came my tweens and teens, and mean girls and cool kids. They ro in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found mylf.
Popularity is a well-explored subject in social psychology. Mitch Prinstein, a professor of clinical psychology sorts the popular into two categories: the likable and the status ekers. The likables’ plays-well-with-others qualities strengthen schoolyard friendships, jump-start interpersonal skills and, when tapped early, are employed ever after in life and work. Then there’s the kind of popularity that appears in adolescence: status born of power and even dishonorable behavior.
Enviable as the cool kids may have emed, Dr. Prinstein’s studies show unpleasant conquences. Tho who were highest in status in high school, as well as tho least liked in elementary school, are “most likely to engage(从事)in dangerous and risky behavior.”
In one study, Dr. Prinstein examined the two types of popularity in 235 adolescents, scoring the least liked, the most liked and the highest in status bad on student surveys(调查研究). “We found that the least well-liked teens had become more aggressive over time toward their classmates. But so had tho who were high in status.
It clearly showed that while likability can lead to healthy adjustment, high status has just the opposite effect on us."
