1、考点规范练8.阅读理解A(2019全国)As data and identity theft becomes more and more common,the market is growing for biometric(生物测量) technologieslike fingerprint scansto keep others out of private e-spaces.At present,these technologies are still expensive,though.Researchers from Georgia Tech say that they have com
2、e 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 users typi
3、ng 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
4、 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
5、 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 devel

9、problems in children.“A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort,or because their nearsightedness appears to be increasing and theyre worried,”he says.Dr.Bonilla-Warford says part of the problem is t
10、hat children may be more likely to pay no attention to early warning signs than adults.“Even if their eyes start to feel uncomfortable or they start to get a headache,theyre less likely to tell their parents,because they dont want to have the game or the computer or whatever taken away,”he explains.
11、He says another part of the problem is that people blink(眨眼) less often when they use digital devices.He says,“A person who uses an electronic device blinks about one third as much as we normally do in everyday life.And that can result in the front part of the eye drying and not staying protected li
12、ke normal.”Eye doctors offer suggestions like the following which is known as the 20/20/20 rule.That means every twenty minutes looking away twenty feet or more for at least twenty seconds from whatever device youre using.Other suggestions include putting more distance between you and the device and
13、 using good lighting.Of course,another way is to spend less time looking at screens.Many experts say children should spend no more than two hours a day using digital deviceswith no screen time for children under two.But not all eye doctors have noticed an increase in problems in children.Dr.David Hu
14、nter,from Boston Childrens Hospital,has not seen an increase in his practice.“While it is possible to develop fatigue looking at screens for a long period of time,theres certainly no proof that it actually causes any damage to the eyes,”he says.5.Which of the following is TRUE according to the passa
15、ge?A.Dr.Bonilla-Warford thinks using computers causes nearsightedness.B.People keep their eyes protected against drying by blinking normally.C.Children under two can watch TV for less than two hours a day.D.Dr.David Hunter says headaches cause an increase in eye problems.6.The syndrome in children i
