“Iris scan (虹膜扫描) , please,” the bank’s computer voice tells you . You step up and the computer reads your eye , comparing it to the stored file it has of your iris. The images had better match—otherwise you won’t be able to get your money.
Iris scanning and other technologies , such as fingerprint and voice scanning , have appeared in many science fiction movies in the past. Today , these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics( 生物测定学) a fast developing area of automatic personal identification technology . Basically , biometrics uses various ways to verify a persons identity , based on the individual’s unique characteristics ,including fingerprints , voices, irises, body heat patterns, facial images, handprints , signatures and so on.
Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember , forget, lose or steal.
The voice scan is the simplest and most affordable form of biometrics . It only requires a computer, a microphone and the correct software. The software records a subject’s voice and then compares it to a stored voice sample for identification purposes.
For additional safety, fingerprint and handprint scans can also be employed . Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand.
Iris scans currently give the highest level of accuracy among all the available biometrics systems. Another technology , full facial scans , is currently in use at border crossings and airports. Facial scanning equipment can actually track and identify moving faces within a crowd.
The potential of biometrics is exciting and encouraging . With continued development , testing , and application , current technologies will become even more effective in the future. Soon , the days of password and car keys will be gone . Just don’t leave home without your fingerprints!

A new system that scans customers’ fingerprints and subtracts(减去)the grocery bill from their bank accounts has taken supermarkets in Germany to use the new system. “Almost a quarter of our customers pay with their fingers,” said an employee at the headquarters. Edeka has tried the system at 70 of its supermarkets. It says it will introduce it at 200 others because customers like it.
“At first we thought that only the young who really keep up with the latest technology would be interested, but we were wrong,” said Stefan Sewoester from IT Werke. “Almost two-thirds of the people who use the system are 40 and older,” he said.
IT Werke, a computer company, is one of the pioneers of fingerprint payment software in Germany. It has helped about 150 shops, canteens and bars to put in the fingerprint scanning machines. Each costs about 2,000 euros.
To sign up for the service, customers must have their fingerprints taken and leave their addresses and banking details with the shop. The shop then takes the cost of goods directly out of the customer’s bank account.
“It is especially a good thing for elderly people. Now they do not have to remember their pin to pay with their bank cards, or to scratch around for their glasses or cash.” Sewoester said.
The stores benefit from the system too. It saves more than time in the check-out line. It also cuts out the hidden costs of accepting electronic card payments.
1.According to the passage, the fingerprint system______.
A.was invented by the Edeka supermarket chain |
B.has caused payment revolution in Germany |
C.is more popular with young people |
D.is preferred by most American customers |
2.To apply to pay with fingers, customers are required to do all of the following EXCEPT______.
A.have their fingerprints taken |
B.leave their addresses |
C.give the shop information about the bank accounts |
D.have their phones connected with computers |
3.Why do elderly people benefit much from the fingerprint machine?
A.They will spend less time on shopping.. |
B.They are not forgetful. |
C.They don’t like to pay in cash |
D.They always fail to find their bank cards. |

The Amazon Echo, a voice-driven cylindrical computer that sits on a table top and answers to the name Alexa, can call up music tracks and radio stations, tell jokes, answer trivia questions and control smart appliances; even before Christmas it was already resident in about 4% of American households. Voice assistants are proliferating in smartphones, too: Apple’s Siri handles over 2bn commands a week, and 20% of Google searches on Android-powered handsets in America are input by voice. Dictating e-mails and text messages now works reliably enough to be useful. Why type when you can talk?
Simple though it may seem, voice has the power to transform computing, by providing a natural means of interaction. Windows, icons and menus, and then touchscreens, were welcomed as more intuitive ways to deal with computers than entering complex keyboard commands. But being able to talk to computers abolishes the need for the abstraction of a “user interface” at all. Just as mobile phones were more than existing phones without wires, and cars were more than carriages without horses, so computers without screens and keyboards have the potential to be more useful, powerful and ubiquitous than people can imagine today.
Voice will not wholly replace other forms of input and output. Sometimes it will remain more convenient to converse with a machine by typing rather than talking (Amazon is said to be working on an Echo device with a built-in screen). But voice is destined to account for a growing share of people’s interactions with the technology around them, from washing machines that tell you how much of the cycle they have left to virtual assistants in corporate call-centres. However, to reach its full potential, the technology requires further breakthroughs—and a resolution of the tricky questions it raises around the trade-off between convenience and privacy.
Computer-dictation systems have been around for years. But they were unreliable and required lengthy training to learn a specific user’s voice. Computers’ new ability to recognise almost anyone’s speech dependably without training is the latest manifestation of the power of “deep learning”, an artificial-intelligence technique in which a software system is trained using millions of examples, usually culled from the internet. Thanks to deep learning, machines now nearly equal humans in transcription accuracy, computerised translation systems are improving rapidly and text-to-speech systems are becoming less robotic and more natural-sounding. Computers are, in short, getting much better at handling natural language in all its forms
Although deep learning means that machines can recognise speech more reliably and talk in a less stilted manner, they still don’t understand the meaning of language. That is the most difficult aspect of the problem and, if voice-driven computing is truly to flourish, one that must be overcome. Computers must be able to understand context in order to maintain a coherent conversation about something, rather than just responding to simple, one-off voice commands, as they mostly do today (“Hey, Siri, set a timer for ten minutes”). Researchers in universities and at companies large and small are working on this very problem, building “bots” that can hold more elaborate conversations about more complex tasks, from retrieving information to advising on mortgages to making travel arrangements.
Many voice-driven devices are always listening, waiting to be activated. Some people are already concerned about the implications of internet-connected microphones listening in every room and from every smartphone. Not all audio is sent to the cloud—devices wait for a trigger phrase (“Alexa”, “OK, Google”, “Hey, Cortana”, or “Hey, Siri”) before they start relaying the user’s voice to the servers that actually handle the requests—but when it comes to storing audio, it is unclear who keeps what and when.

A.has been sold out before Christmas
B.has been used by most American families

高二英语阅读理解中等难度题查看答案及解析
I log onto a computer at the doctor’s office to say I have arrived and then wait until a voice calls me into the examination room.
There, a robotic nurse directs me onto a device and then takes my blood pressure. Some time later, in steps the doctor, who is also a robot. He notes down my symptoms and gives me a prescription. I pay for my visit using a credit card machine and return home without having met another human being.
This scenario(场景) is my nightmarish(噩梦般的) vision of the future, which hasn’t come to pass—at least not yet.
I should say I really do like many aspects of technology. I am a big fan of air conditioning in the summer and heaters in winter. But I am writing this because I don’t want machines to take over.
When I call my dentist's office and actually get a human being on the line, I am thrilled. And when I see the introduction of yet more self-service checkout stations at the grocery store, I feel like shouting: "When it comes to cashiers(收银员), make mine human, please!"
After all, human cashiers sometimes give you a store coupon (优惠券) for items you are buying. Even more than that, real-life cashiers often take an interest in particularly cute children, which can brighten a young mother's day. A cashier may also show compassion for an elderly person struggling to get that last penny out of her purse.
Machines can be efficient and cost-effective and they often get the job done just fine. But they lack an element so crucial to everyday life.
It is being human that prompts(促使) us to smile at others, which may be what they need at that moment. Call it the spirit, the soul or the heart. It is something no machine will ever have.
1.What’s the author’s purpose in writing the first two paragraphs?
A. To indicate high technology can make our future life very efficient.
B. To warn readers of the possible dangers of robotic nurses and doctors.
C. To describe a possible future scene where robots take control of our life.
D. To predict how technology can affect we see a doctor in the future.
2.What is the main reason that the author prefers being served by humans rather than by robots?
A. Robots don’t offer to give store coupons.
B. Robots are indifferent and emotionless.
C. Services from robots cost less time and more money.
D. Robots can’t do a job as well as humans do.
3.What does the underlined word “element” mean in the eighth paragraph?
A. Humor. B. The ability to speak.
C. Methods. D. Effective communication.
4.What’s the main idea of the text?
A. The opinion about using man or machine.
B. Machines give people a lot of convenience.
C. Being human service is better than service from machines.
D. Being human service cost little money.
