2019年河北高考英语真题及答案(文字版)

　　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 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.

　　28. Why do the researchers develop the smart keyboard?

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

　　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 rose in the ranks not by being friendly but by smoking cigarettes, breaking rules and playing jokes on others, among whom I soon found myself.

　　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 seekers. 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 seemed, Dr. Prinstein’s studies show unpleasant consequences. Those who were highest in status in high school, as well as those 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 based 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 those 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."

　　Dr. Prinstein has also found that the qualities that made the neighbors want you on a play date-sharing, kindness, openness — carry over to later years and make you better able to relate and connect with others.

　　In analyzing his and other research，Dr. Prinstein came to another conclusion: Not only is likability related to positive life outcomes, but it is also responsible for those outcomes, too. "Being liked creates opportunities for learning and for new kinds of life experiences that help somebody gain an advantage, ” he said.

　　32. What sort of girl was the author in her early years of elementary school?

　　A. Unkind. B. Lonely. C. Generous. D. Cool.

　　33.What is the second paragraph mainly about?

　　A. The classification of the popular.

　　B. The characteristics of adolescents.

　　C. The importance of interpersonal skills.

　　D. The causes of dishonorable behavior.

　　34. What did Dr. Prinstein’s study find about the most liked kids?

　　A. They appeared to be aggressive.

　　B. They tended to be more adaptable.

　　C. They enjoyed the highest status.

　　D. They performed well academically.

　　35. What is the best title for the text?

　　A. Be Nice-You Won’t Finish Last

　　B. The Higher the Status, the Beer

　　C. Be the Best-You Can Make It

　　D. More Self-Control, Less Aggressiveness
