Some wonderfully creative uses of X-rays have been in the world of art．But the most impressive one is to uncover what has been covered up．Details unfolded by an X-ray of a painting can ' t be seen any other way．For example, in the past, paintings were often repaired if small pieces of paint fell off the canvas （帆布）． These repairs cannot be seen just by looking at the painting．It takes an X-ray to discover where the repairs have been made．
An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery（赝品）．If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original．If the brushstrokes （笔迹） , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy．
Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different．This is another way X-rays can be used to spot a forgery．A modem artist will try to make a forgery look hundreds of years old by painting dirty varnish on it or by using artificial means to get the varnish to look cracked．To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the deception is obvious．
It was common many years ago for an artist to finish a painting, decide it wasn't any good, and paint a completely different picture on top of it．Or artists would paint over others' work —it was their version of recycling．Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes．Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed．
【小题1】What is the main purpose of the article?

Madame Curie ,the youngest of five children ,was born in Warsaw ,Poland in 1867. Marie Curie's maiden name was Manya. Her parents were teachers,and she learned the importance of education at an early age. No higher education was offered to women in Poland at that time,so Manya took a job as a governess(女家庭教师). She sent part of her income to Paris to help pay for her older sister's medical studies. Her sister qualified as a doctor and married a fellow doctor in 1891. Manya went to join them in Paris ,changing her name to Marie. She entered the Sorbonne(now the Universities of Paris)and studied physics and mathematics, graduating at the top of her class. For the research she wanted to do , she was introduced to another young scientist, Pierre Curie. Later they fell in love with each other . After their marriage, they worked together on radioactivity.

Fame troubled Marie Curie and also her husband, because science was their world and in this world of science fame and honor to persons had no value. One day when a writer for a newspaper tried to ask Marie about herself and her thoughts and her beliefs, she answered him, “In science we must be interested in things,not in persons.” Much of the real character and spirit of this unusual woman was found in these few words,which she was later often to repeat. One evening, at a big party,a friend asked if she would like to meet the King of Greece,who was also a guest.She answered in her simple manner, “I don't see the value of it.” Then,seeing that she had hurt the feelings of her friend, she quickly added, “But …but…of course,I shall do whatever you please. Just as you please.”

Much of the water we use comes from snow. Melting snow provides water for rivers, electric power centers and agricultural crops. In the western United States, mountain snow provides up to 75% of all surface water supplies.
Snowfall helps to protect plants and some wild animals from cold, winter weather. Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.
Snow also is known to influence the movement of sound waves. When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow's surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. This gives them their color. However, when light travels from air to snow, some light is sent back, or reflected. Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.
Sometimes, snow or ice may appear to be blue. The blue light is the product of a long travel path through the snow or ice. In simple terms, think of snow or ice as a filter. A filter is designed to reject some substances, while permitting others to pass through. In the case of snow, all the light makes it through if the snow is only a centimeter thick. If it is a meter or more thick, however, blue light often can be seen.
【小题1】How many functions of snow are discussed in the passage?
