Unit 3 The world online 高考专题大建构 ●答案见D27 「.阅读理解 A 主题语境 人与社会—智能键盘 a smart keyboard, 与身份识别 语篇类型说明文词数243关键词 people's identities [2019I ]As data and identity theft becomes more and more common,the market is growing for biometric()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()that gets around this problem:a smart keyboard.This smart keyboard precisely measures the cadence()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. 1.Why do the researchers 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. 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 security measures are guaranteed. 3.What do the researchers 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. 11165/11111 高考快递·练习生 高中英语·必修第三册·YL 4.Where is this text most likely from?

B 主题语境 人与社会一用于监测牛 群健康的机器人 语篇类型 说明文词数307 关键词 robot,monitor,the health of grazing cattle [2021新高考Ⅱ卷]An Australian professor is developing a robot to monitor the health of grazing cattle,a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage. Salah Sukkarieh,a professor at the University of Sydney,sees robots as necessary given how cattlemen are aging.He is building a four-wheeled robot that will run on solar and electric power.It will use cameras and sensors to monitor the animals.A computer system will analyze the video to determine whether a cow is sick.Radio tags (on the animals will measure temperature changes.The quality of grassland will be tracked by monitoring the shape,color and texture (of grass.That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes. Machines have largely taken over planting,watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes. For Texas cattleman Pete Bonds,it's increasingly difficult to find workers interested in watching cattle.But Bonds doesn't believe a robot is right for the job.Years of experience in the industry-and failed attempts to use technology-have convinced him that the best way to check cattle is with a man on a horse.Bonds,who bought his first cattle almost 50 years ago,still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick. Other cattlemen see more promise in robots.Michael Kelsey,vice president of the Oklahoma Cattlemen's Association,said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen,making them appealing targets. 5.What is a problem with the cattle-raising industry? A.Soil pollution. B.Lack of workers. C.Aging machines. D.Low profitability. 6.What will Sukkarieh's robot be able to do? A.Monitor the quality of grass. B.Cure the diseased cattle. C.Move cattle to another field. D.Predict weather changes. 7.Why does Pete Bonds still hire cowboys to watch cattle? A.He wants to help them earn a living. B.He thinks men can do the job better. C.He is inexperienced in using robots. D.He enjoys the traditional way of life. 8.How may robots help with cattle watching according to Michael Kelsey? A.Increase the value of cattle. B.Bring down the cost of labor. C.Make the job more appealing. D.Keep cattle from being stolen. 11111661 Unit 3 The world online ‖.七选五 主题语境 人与自我—网路课堂 online class, 与人际交往 语篇类型说明文词数270关键词 communication [2019I]In an online class,developing healthy patterns of communication with professors is very important.1.
