【篇章听译教程】第一期 Passage 05
If you break your arm or leg, the doctor will probably send you to a hospital to have an X-ray photograph taken to find out just where the break is and what kind of break it is. If a small child swallows a coin or some other hard object, as sometimes happens, the doctor will take an X-ray photograph of the child's stomach. Every hospital has an X-ray department, and doctors now depend on these photographs to find out if there is anything wrong with the lungs, for example, which can not be seen from outside the body.
X-rays were first discovered by a German scientist, Wilhelm Konrad Rontgen, in 1895, almost by accident.
He and other scientists were experimenting with passing electric currents through certain gases in a special glass tube. Then one day Rontgen noticed that, even when the tube was covered with black paper, some strange kind of radiation was coming through. This aroused Rontgen's curiosity. 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. So Rontgen made the first X-ray picture of a hand, showing just how the bones in the hand fit together.
When Rontgen wrote an account of what he had discovered, he called these new rays X-rays, for "X" is a symbol often used for something which is not yet understood. Other scientists called them Rontgen rays in honor of the man who first found them, but X-ray is the name now commonly used.
