NCR has shown its first example machine that is believed to be the future of banking. Instead of asking you for your PIN on a screen, the super teller--Stella for short, asks you orally through a loudspeaker to look straight ahead while an infrared camera turns to your head, then your eye, and finally takes an infrared photograph of your iris (虹膜). For identification purposes, an iris picture is better than a fingerprint, with around 256 noticeable characteristics compared with 40 for fingerprints. This means that the chances of someone else being recognized in your place is about 1 in 1020. Once you've been identified, Stella greets you by name and says, "Would you like cash or a statement？" An infrared port allows the machine to send a bank statement straight to your palmtop computer.
What is this new machine called？
A．Stella.
B．ATM.
C．PIN.
D．NCR.

Is staring at a big, white wall during class making you feel dull？ If you have ever walked past math teacher Mr. Kelley' s room, you may have noticed how cheerful it is throughout the year. One thing that makes his classroom so much fun is the celebrity (名人) pictures on his front wall. Kelley ' s students have been writing to celebrities from across the nation asking for a photo and a few words of advice. "It really takes a lot of time and money," Kelley said. First, Kelley and his students make a list of all the celebrities to whom they want to write. Once a student picks a star, Kelley looks them up in his book of addresses to see if he can write to that person.
Writing to the stars takes a lot of time because he has personalize each letter, print them out, and address them. In the letter, Kelley asks the celebrity to send his classes a picture with some advice he or she would give to today' s youth.
Kelley takes up a collection in all of his classes and asks each student to contribute (捐) a dollar to pay for the postage. Once Kelley mails off all the letters, the fun really begins. So far he has gotten back about 20 letters and pictures. "The only thing that isn' t cool is when the celebrity sends the picture back with no advice on it, which is my entire purpose in doing this, " said Kelley. When he gets at least three pictures retumed, he lets his classes guess who the three stars are. He keeps score of how many celebrities each class has guessed. Jason Bryant, a student, said, "It' s become a contest (竞赛) between the classes to see who can guess the most stars, and it' s really fun. "
56. What is the text about？
[ A] Celebrities sending photos to Kelley.
[ B ] Celebrities giving advice to students.
[ C] Kelley and his classes writing to celebrities.
[ D] Kelley inviting celebrities to his classes.

听力原文： When I was walking down the street the other day, I happened to notice a small brown leather wallet lying on the sidewalk. I picked it up and opened it to see if I could find out the owner's name. There was nothing in side it except some change and an old photograph -- a picture of a woman and a young girl about twelve years old, who looked like the woman's daughter. I put the photograph back and' took the wallet to the police station. That evening I went to have dinner with my aunt and uncle. They had also invited a young woman so that there would be four people at the table. Her face was familiar. I was quite sure that we had not met before, but I couldn't remember where I had seen her. In the course of the conversation, however, the young woman happened to mention that she had lost her wallet that afternoon. All at once I realized where I had seen her. She was the young girl in the photograph, although she was now much older. She was very surprised, of course, when I was able to describe her wallet to her. Then I explained that I had recognized her from the photograph I had found in the wallet. My uncle insisted on going to the police station immediately to claim the wallet. As the-police sergeant handed it over. he said that it was amazing that I had not only found the wallet, but also the person who had lost it.
(33)
A．Because he wanted to find some money.
B．Because he wanted to find the owner's name.
C．Because he wanted to find the owner's photograph.
D．Because he was curious about what was inside it.

Digital Camera
In the past twenty years, most of the major technological breakthroughs in consumer electronics have really been part of one larger breakthrough. Whet, you get down to it, CDs, DVDs, HDTV, MP3s and DVRs are all built around the same basic process: convening conventional similar information(represented by a fluctuating wave) into digital information (represented by ones and zeros, or bits). This fundamental shift in technology totally changed how we handle visual and audio information—it completely redefined what is possible.
The digital camera is one of the most remarkable instances of this shift because it is so truly different from its ancestor. Conventional cameras depend entirely on chemical and mechanical processes, you don't even need electricity to operate them. On the other hand, all digital cameras have a built-in computer, and all of them record images electronically.
The new approach has been enormously successful. Since film still provides better picture quality, digital cameras have not completely replaced conventional cameras. But, as digital imaging technology has improved, digital cameras have rapidly become more popular.
Understanding the Basics
To get a digital image, you need the image to be represented in the language that computers recognize—bits and bytes. Essentially, a digital image is just a long string of 1s and 0s that represent all the tiny colored dots—or pixels(像素)—that collectively make up the image.
If you want to get a picture into this form, you have two options:
You can take a photograph using a conventional film camera, process the film chemically, print it onto photographic paper and then use a digital scanner to sample the print(record the pattern of light as a series of pixel values).
At its most basic level, this is all there is to a digital camera. Just like a conventional camera, it has a series of lenses that focus light to create an image of a scene. But instead of focusing this light onto a piece of film, it focuses it onto a semiconductor device that records light electronically. A computer then breaks this electronic information down into digital data.
A Filmless Camera
Instead of film, a digital camera bas a sensor that converts light into electrical charges. The image sensor employed by most digital cameras is a charge coupled device(CCD). Some cameras use complementary metal oxide semiconductor(CMOS) technology instead. Both CCD and CMOS image sensors convert light into electrons. A simplified way to think about these sensors is to think of a 2-D array of thousands or millions of tiny solar cells.
Once the sensor converts the light into electrons, it reads the value(accumulated charge) of each cell in the image. This is where the differences between the two main sensor types kick in:
A CCD transports the charge across the chip and reads it at one corner of the array. An analog-to-digital converter(ADC) then turns each pixel's value into a digital value by measuring the amount of charge at each photosite and converting that measurement to binary(二进制) form.
CMOS devices use several transistors at each pixel to enlarge and move the charge using more traditional wires. The CMOS signal is digital, so it needs no ADC.
Capturing Color
Unfortunately, each photosite is colorblind. It only keeps track of the total intensity of the light that strikes its surface. In order to get a full color image, most sensors use filtering to look at the light in its three primary colors. Once the camera records all three colors, it combines them to create the full spectrum(光谱).
There are several ways of recording the three colors in a digital camera. The highest quality cameras use three separate sensors, each with a different filter. Another meth

Millions of Americans survive (生产) in low-paying jobs. The Working Poor (319 pages), by David Shipler, a Pulitzer-winning former reporter, shows just how barely they get by.
In his tour around the world of low-paying jobs, Shipler describes a kind of domino model of a downward cycle." Poor housing can worsen a child's illness, which leads to a call for a doctor, which results in a medical bill that cannot by paid, which ruins a credit record, which raises the interest rate on an auto loan (贷款), which results in the buying of a used car, which causes a mother to be late for work, which limits her pay raise and earning ability, which keeps her to poor housing, which worsens the illness, and so on."
What Shipler aims to do in the book is to produce a picture of all of those dominoes at once, the problems that keep the working poor on the edge of household disaster (灾难). As the conditions for the lowest-paid workers keep worsening, he writes," the low-paid employees have been testing the American belief in hard work."
To those who don't quite make it from paycheck to paycheck, convenience stores in poor neighborhoods lend money at interest rates of about of 20% for a two-week loan. If that can't be repaid, it's gladly rolled over—for another 20%. In the space of a few months, he or she owes twice as much in interest as he borrowed.
Shipler doesn't place all the blame on society. The people he meets often lack the soft skills that employers require, like showing up on time, following directions, even knowing how to comb their hair. To be sure, they need better schools and medical care, but they also need to know better than to use their hard-earned checks to get drunk and disorderly, or go in for ill-advised sex and foolish spending.
The main purpose of this text is to ______.
A．show how the poor can improve their living conditions
B．discuss the reasons why many Americans are poor
C．introduce David Shipler' s book about the poor
D．describe how a reporter has become a writer
第10题
Recent economic hardship has given the consumer increased power in Europe as retailers(零售商) fight to win their share of reduced disposable(可任意使用的)income. This has meant falling prices, plenty of special offers and a re-examination of what customer service really means. People often point to America as an example of sophisticated customer service. In restaurants in the south of the USA, for example, waiters compliment(称赞) you on your clothes, ask about your day, compliment you on the wisdom of your order and then return every ten minutes to refill your glass and make sure that everything is to your satisfaction.
Anyone who has waited 30 minutes to be served in a restaurant might well dream of such attention, but do Europeans really want US style. service？ As a friend of mine once told me, "By the end of the evening I had spent as much time talking to the waiter as to my wife. It is a question of expectations. Different nationalities expect different types of service.
Attitudes to service are, of course, affected by employers attitudes to their workers. As American sales and service personnel are heavily reliant(依赖) on commission and tips, they have more incentive(动机) to provide more service. But is this fair？ Do we think it is fair to ask shop assistants to work late evenings, Sundays and lg hour shifts？ Does it fit in with our picture of society？ It might not be a case of "Is the customer always right？" but a case of "How much service is it fair to expect？"
The Europeans have to reexamine what customer service means because______.
A．retailers are under increasing pressure to improve their service and cater more for consumer demands
B．America has been set as an example of good customer service
C．they are aware that attitudes to shopping and consumers may vary in different countries
D．consumers income has been reduced
