What if software could get a car back on track if the driver changes direction suddenly on ice? Or help a stroke (中风) patient smoothly lift a cup?
Bioengineers have developed a mathematical program for a robot that can “see” your intention while performing an ordinary action,like driving straight up a road or reaching for a cup — even if the action is interrupted (打断) .
“Say you’re reaching for a piece of paper and your hand is in mid-reach — your nerves take time to respond to what has happened,” said Justin Horowitz,first author of the study. So,when something unexpected happens,the signal going to your hand can't change for at least a tenth of a second."
In the test,Horowitz employed exactly the situations he described. He analyzed(分析) the movement of research subjects as they reached for an object on a desk,but had their hand pushed in the wrong direction. He used the advanced mathematical program to analyze the action and examine the subjects’ intent,even when there was a disturbance.
The program has extra sensors and deals with information so much faster than people can react. It can predict the way you wanted to move,according to your intention. The car’s artificial intelligence would use it to bring the car’s course more in line with what the driver wanted to do. aIf we hit a patch of ice and the car starts changing direction,we want the car to know where we meant to go ,” he said. “It needs to correct the car's course not to where I am now pointed,but to where I meant to go."
9. The mathematical program can be used to.
A. prevent cars from speeding
B. help the disabled learn to drive
C. predict people’s intended acts
D. warn drivers of possible dangers
10. The underlined part “mid-reach” in Paragraph 3 refers to the time when .
A. the brain sends signals
B. your body reacts to something
C. you react to something unexpected
D. the brain is stuck in a dangerous situation
11. What is stressed about the program in the last paragraph?
A. Its cost. B. Its future,
C. Its function. D. Its structure.
12. Where can we probably read the text?
A. In a car review. B. In a business ad.
C. In a research plan. D. In a science report.
C篇科学家研究出能够读懂人意愿的程序,该程序 可以应用到机器人上帮助人们。
9.C. 细节理解题。由第二段中的a robot that can “see” your intention while performing an ordinary action可知,人们在做一般性的事情时,该程序可 以预测到人们的行动意愿。
10.B. 推理判断题。由第三段中的 your nerves take time to respond to what has happened 可知, mid-reach是指“你的身体对信息的反应过程”。
11.C. 段落大意题。从内容上看,最后一段主要介 绍了该程序的功能。
12.D. 文章出处题。本文主要介绍了一种能够读懂 人意愿的程序及其应用,故很有可能选自科技报 道。
