  X-rays were first discovered by a German scientist, Wilhelm Konrad Rontgen, in 1895, almost by accident.He and several other scientists were experimenting with passing electric currents through certain gases in a special glass tube from which the air had been moved.One day Rontgen noticed that, even when the tube was covered with black paper, some strange kind of radiation was coming through and making a screen nearby glow.Ronghen could not see anything coming out of the tube, but then he discovered that if he put the screen in the next room on the other side of a closed door, the rays could pass not only through black paper but also through wood.

  The next thing he found out was that if he put his hand between the rays and a photographic plate, the rays would print a shadow of the bony framework of his hand on the plate.In fact, the rays could pass as easily through the fleshy part of his hand as through the black paper, but hardly at all through the bone.So Rontgen made the first X-ray picture of a hand, showing just how the bones in the hand fit together.

The Western has been the favorite type for American adventure story since the nineteenth centu??ry. While the American West was being settled, newspapers and "dime novels" could depend on stories of the frontier settlements and tell tales about living in the untamed wilderness to sell. The public back East was eager to read about the West, even if the stories were more fiction than fact.

In 1902, Owen Wister published his novel The Virginian, which was one of the first novels to treat the Western as a serious literary form; the novel still sold well and had inspired several movies and a television series. In 1905, Bertha H. Bower and Zane Grey published their first novels, and the popular Western novels had continued to flourish from that day on, with current novels by Luke Short, Max Brand, and Louis L’ Amour carrying on the tradition.

The first Western movie appeared even earlier than these serious Western novels. Before the turn of the century, an associate of Edison’s had filmed Cripple Creek Barroom Scene, a few seconds of film showing the inside of a saloon, to help publicize the invention of the movie camera. In 1903 the Edison’ company filmed the first "full-length" Western — The Great Train Robbery. The film lasts less than fifteen minutes, but a story is told its entirety. In the movie, bandits (强盗) rob a train and its passengers, killing the engineer, and find themselves tracked down by a posse. Audiences loved the movie. Some theaters were actually opened for the single purpose of showing The Great Train Rob??bery and only later realized that they could do equally well showing other movies. The film was so suc??cessful that other companies, and finally even the Edison company itself, began producing copies and other versions of The Great Train Robbery. Ironically, in" an era when the West was still very real —-Arizona, New Mexico and Oklahoma were all territories rather than states in 1903 — The Great Train Robbery was filmed in New Jersey.  

9. The purpose of this passage is to________.

A. discuss the making of the movie The Great Train Robbery

B. discuss the early Western novels

C. discuss the art of movie making

D. trace the development of the Western as an American adventure story tradition

10. We can conclude from this passage that________.

A. people lost interest in the West after 1903

B. Owen Wister was an ex-cowboy

C. New Jersey was still "untamed wilderness" in 1903

D. films were fairly uncommon at the time The Great Train Robbery was made

11. The passage suggests that________.

A. Edison’s invention of the movie camera happened;by accident

B. movie houses didn’t make much-money in the early days

C. Easterners were fascinated by the " wild West"

D. The Great Train Robbery was poorly received by the public because it lacked a plot

Honesty may well be the policy, but it often deserts us when no one is watching, psychologists report today. Experiments with an honesty box to collect payments for hot drinks show that people are better at paying up when under the gaze(注视) of a pair of eyes. The surprise was that the eyes were not real, but photographed.

Researchers at Newcastle University set up the experiment in secret. They attached a poster to a cupboard of mugs above an-honesty box alongside a kettle ,with tea, coffee and milk. Over 10 weeks, they alternated each week between images of eyes and pictures of flowers.

Dr. Bateson, a behavioral biologist and leader of the study, said that even though the eyes were not real they still seemed to make people behave more honestly. They effect may arise from behavioral characteristics that developed as early humans formed social groups that increased their chances of survival. Individuals had to co-operate for the good of the group, rather than act selfishly.

"If nobody is watching us it is in our interests to behave selfishly. But when we think we're being watched we should behave better, so people see us as co-operative and behave the same way towards us, "Dr. Bateson said.

"We thought we'd get a slight effect with eyes, but it was quite striking how much difference they made. Even at a subconscious(潜意识的) level, it seems people respond to eyes, and that might be because eyes send a strong biological signal we have evolved(进化) to respond to."

The finding, which researchers believe sheds light on our evolutionary past, could be turned to practical use. The psychologists say images of eyes could promote ticket sales on public transport and improve monitor systems to prevent antisocial behavior.

1.This passage is mainly about _______________.

A.the policy of honesty

B.an honesty box to collect money

C.evolution on honesty

D.an experiment on honesty

2.The reason for doing the experiment secretly is that the researchers _____________.

A.wanted to get a comparatively more exact result

B.had known they wanted to do something illegally

C.meant to get the co-operation of their colleagues

D.intended to sell the hot drinks at a higher price

3.People behave honestly under watchful gaze of eyes because _____________.

A.they want to leave a good impression

B.they fear to be laughed at by others

C.they've got the nature through evolution

D.they take the photo for a real pair of eyes

4.The underlined phrase" sheds light on" in the last paragraph means _____.

A.causes somebody to become cheerful
