1、考点突破备战高考专题18 阅读理解（科普类）1.C【2019全国I】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 t
2、hat 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 for
3、ce of a users typing 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 do

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 c

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.2

The researchers then tested how the monkeys combinedor addedthe symbols to get the reward.Heres how
