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.

The demands of the modern world are growing day by day and this is putting more pressure on scientists to do research. However, as stated by Griffiths, “There is no hope of doing perfect research”. Naturally, there have been a lot of criticisms (批评), as many scientists immediately announce that their research methods are very safe and that they have the perfect research theory (理论).

However, scientific history is filled with examples, in which a perfect scientific solution that was based on decades of scientific research has been overturned (推翻) with new theories. Naturally the first example that comes to mind is the fact that Newton’s Theories were thought to be very safe and they were used in all fields of science. For centuries, thousands of scientists around the world used Newton’s Theories to formulate (规划) other theories.

However, after nearly two centuries of use, Newton’s Theories were found to be not as perfect as they were thought. Through Einstein’s publication on the General Theory of Relativity, it was found that Newton’s laws were imperfect in explaining all motions (运动) that were taking place in our universe. It was found to be imperfect under some conditions, even though, Newton’s laws are still used today to predict motion at low speeds.

Thus, perfect research is only a myth (神话). Of course, this does not mean that a scientist should simply give up and accept imperfection in his or her research efforts. Improvements and changes in research techniques and methods are a natural part of evolution (进化) and it is each scientist’s responsibility to take it forward as much as possible.

While the final answer to the universe’s questions may never exist, a time will come when there will be fewer questions as new answers are found and more improved research is carried out by scientists around the world.

1.Why have there been a lot of criticisms?

A. The modern world demands mor e and more.

B. Scientists have a negative attitude.

C. Many scientists arrive at their conclusions (结论) too fast.

D. Griffiths does not believe what scientists say.

2.Through the publication of the General Theory of Relativity, Newton’s Theories turned out to be ______.

A. not so perfect　　 B. completely wrong　　 C. very safe　　 D. very exact

3.What will scientists do to deal with the “imperfectness” problem?

A. Accept the fact and give up.

B. Improve and change their methods and techniques.

C. Try their best to carry out the perfect study.

D. Ignore it and do as they please.

4.We can learn from the last paragraph that ______.

A. the universe’s questions are sure to have a final answer

B. the number of questions is sure to increase with the passing of time

C. scientists are carrying out improved studies

D. there will be more scientists in the world in the future
