A scanner is recently created by a group of professors. It is believed to predict the perfect job for anyone simply by reading their fingerprints. The group says that in the future, fingerprints could help tell a person’s key personalities.

To use the scanner, people place their fingers upon the fingerprint reader and computer technology connected with sensors (传感器) reads back what sort of job could suit the individual. The machine bases its results on a collection of a large amount of information in the computer about how fingerprint shapes connect with job selection.

Local companies help researchers from the city’s Kuban University of Physical Education and Sport to test the technology.

Twenty - one - year - old Oscar Galkin, a mathematics graduate, said: “I got the result from the scanner that I would suit a job in IT, which is exactly what I want to do. I don’t know if it is luck or if it can really read a person’s talents, but it worked for me.”

And Zara Tokareva, aged 20, who feels uncomfortable at the sight of blood, said: “I want to be a house designer but the machine said I should be a nurse. So, no, I don’t think it is as clever as expected.”

Though fingerprint identification has been widely used in crime discovering, it is still a science that has a lot of possibility of being used, say experts, from discovering drug misuse to personality analysis - exactly as hand readers have been saying to do for centuries.

“The basic idea is that although everybody’s fingerprints are completely different, there are obvious features that are common on the fingers of certain professionals working in certain jobs,” said researcher Ravil Yudin.

It’s not really a new idea because hand readers have been saying for hundreds of years that you can tell a person’s future by reading their hands. We want to match that by looking at fingerprints and trying to tell what career path people would choose.

1.From the text we know that the fingerprint scanner 　　　　 .

A. matches fingerprints with jobs　　 B. tells people’s personality

C. helps collect job information　　 D. reads individual’s mind

2.What can we learn from what Ravil Yudin said?

A. The fingerprint scanner is based on a new idea.

B. Cerain people’s fingers actually have something in common.

C. Telling one’s future by reading his hands started a few years ago.

D. The technology of fingerprint identification can be used in many fields.

3.What is the main idea of the passage?

A. Hand readers are widely used in life.

B. A fingerprint scanner could tell a person’s personality.

C. A fingerprint scanner could predict a person’s job.

D. A fingerprint scanner could be used in crime discovering.

In the near future, people in some parts of the world will watch a new kind of television. It is called the high definition television or the HD-TV. The main difference between an HD-TV and a normal television is the picture. It is more clear and detailed. This is because the HD-TV has many more points and lines that make a television image. Every color television picture contains thousands of red, green and blue points. They all come together as an image in the eye of the person watching. The points are organized in lines that go across the television screen. There are more than five hundred lines in a normal television. The HD-TV has two times as many. To get this clear picture, you must have a big screen. Experts say people using a small screen will see little difference.

The HD-TV also has clear sound. It is like the sound on a CD. All these improvements make an HD-TV very costly. One kind in Japan now sells for more than twenty thousand dollars .A major problem with the HD-TV is its broadcast signal（传播信号.The signal is bigger than normal because it carries more electronic information.
