“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 person’s identity, based on the individual’s unique characteristics, including fingerprints, signature, 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 purpose.
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.
1.The first paragraph serves as a(n) ________.
A. example B. explanation
C. comment D. conclusion
2.The underline word “verify” in Paragraph 2 probably means “________”.
A. protect B. confirm
C. develop D. change
3.Which is the most accurate form of biometrics?
A. The voice scan
B. The fingerprint scan

A new system that scans customers’ fingerprints and deducts (扣除) the grocery bill from their bank accounts has taken supermarkets in southwestern Germany by storm and is being picked up by hardware stores, school restaurants and even bars are picking it up.
The Edeka supermarket chain is the first retail (零售) business 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 and 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, restaurants and bars to put in the fingerprint scanning machines.
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 a godsend for elderly people because they do not have to remember their pin-code to pay with their bank cards, or to look 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.
Fingerprint date profiling has long been used to control access and for other security purposes in Germany’s airports, laboratories and nuclear power plants. IT Werke plans to keep refining the retail use of the system. It wants to introduce fingerprint payment in school restaurants with an additional feature that might appeal to parents－they could disable their children’s access to junk food.
1.Which of the following can be the best title of the passage?
A. Pay with Fingers. B. New Development in Technology.
C. Supermarket Revolution. D. Change in Computer Software.
2.Most of the people who use the fingerprint system are ______.
A. youngsters B. housewives C. IT fans D. the elderly
3.The underlined word “godsend” probably means ______.
A. great fortune sent by God B. good luck sent by God
C. good things that happen unexpectedly D. gift sent by God
4.What do we know by inference from the passage?
A. Fewer shops will try the new software because of the cost.
B. The new service requires certain personal information.
C. IT Werke should be the largest computer company in Germany.
D. The new change in payment only benefits elderly people.

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 (处方). I pay for my visit using a credit card machine and return home without having met another human being.
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, 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 (同情)for an elderly person struggling to get that last penny out of her purse.
What technological device would do any of this? I don't want to go back to the Stone Age, but I'm also worried about a world run by machines. Sometimes when you're chatting with someone, you discover things you need to know. Maybe a receptionist needs prayers said for a sick child. Maybe a salesperson can offer a bit of encouragement to a customer who is feeling tired.
Machines can be efficient and cost-effective and they often get the job done just fine. But they lack an element so important to everyday life.
Call it the spirit, the soul or the heart. It is something no machine will ever have. It is being human that prompts us to smile at others, which may be what they need at that moment.
1.What's the author's purpose in writing the first two paragraphs?
A. To indicate high technology can make our future life very easy.
B. To describe a possible future scene where robots take control of our life.
C. To warn readers of the possible dangers of robotic nurses and doctors.
D. To predict how technology can affect the way we see a doctoring the future.
2.Why does the author prefer being served by humans rather than by robots?
A. Robots are indifferent and emotionless.
B. Robots can't provide efficient services.
C. Robots don't offer to give store coupons.
D. Robots are unable to do a job as well as humans.
3.What's the author's attitude towards machines?
A. He wishes one day they would come to life.
B. He is absolutely against their existence in his life.
C. He doesn't like they get involved in his life too much.
D. He is afraid they would take the place of human beings.

Before birth, babies can tell the difference between loud sounds and voices. They can even distinguish their mother’s voice from that of a female stranger. But when it comes to embryonic learning (胎教), birds could rule the roost. As recently reported in The Auk: Ornithological Advances, some mother birds may teach their young to sing even before they hatch (孵化). New-born chicks can then imitate their mom’s call within a few days of entering the world.
This educational method was first observed in 2012 by Sonia Kleindorfer, a biologist at Flinders University in South Australia, and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs. When the eggs were hatched, the baby birds made the similar chirp to their mothers—a sound that served as their regular ＂feed me!＂ call.
To find out if the special quality was more widespread in birds, the researchers sought the red-backed fairy wren, another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analyzing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks, ranking them by similarity.
It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs, the more similar were the babies’ begging calls. In addition, the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom’s voice were rewarded with the most food.
This observation hints that effective embryonic learning could signal neurological (神经系统的) strengths of children to parents. An evolutionary inference can then be drawn. ＂As a parent, do you invest in quality children, or do you invest in children that are in need?＂ Kleindorfer asks. ＂Our results suggest that they might be going for quality.＂
1.The underlined phrase in Paragraph 1 means＂____________＂.
A.be the worst B.be the best
C.be the as bad D.be just as good
2.What are Kleindorfer’s findings based on?
A.Similarities between the calls of moms and chicks.
B.The observation of fairy wrens across Australia.
C.The data collected from Queensland’s locals.
D.Controlled experiments on wrens and other birds.
3.Embryonic learning helps mother birds to identify the baby birds which ____________.
A.can receive quality signals
B.are in need of training
C.fit the environment better
D.make the loudest call
