The willow tree contains salicylic acid (水杨酸）. This stops pain，butthere is one problem. Salicylic acid also hurts the stomach. In 1853，aFrench scientist made a mixture from willow that did not hurtthe stomach. However, his mixture was difficult to make, and he did not try to produceor sell it. In 1897，in Germany Felix Hoffmann also made a mixturewith salicylic acid. He tried it himself first it to hisfather because his father was old and in a lot of pain. His father’s, pain wentaway，and the mixture did not hurt his stomach. Hoffmann worked forBayer，a German company. He showed his new drug to hismanager，who tested the drug and found that itworked well. Bayer decided to make the drug. They called it aspirin and putthe Bayer name on every pill. Aspirin was an immediate success. Almosteveryone has pain of some kind, so aspirin answered a true need. Aspirin was cheap, easy totake, and effective. It also lowered fevers. Aspirin was a wonder drug. At first，Bayersold the drug through doctors, who then sold it to their patients. In 1915, the company started to sellaspirin in drugstores. In the United States，Bayer had a pate+ (专利权）on the drug. Other companiescould make similar products and sell them in other countries，butonly Bayer could make and sell aspirin in the UnitedStates. In time， Bayer could no longer own the nameaspirin in the United States. Other companies could make it there，too. However, Bayer aspirin was the most wellknown, and for many years, it was the market leader. the 1950s，newpainkillers were on the market. Aspirin was no longer the only way to treatpain and reduce fever. Bayer and other companies looked for other drugs tomake. However in the 1970s they got a surprise. Doctors noticed that patientswho were taking aspirin had fewer heart attacks than other people. 共用题干 第三篇Ways to Create Colors in a PhotographThere are two ways to create colors in a photograph.One method called additive,starts with three basic colors and adds them together to produce some other color. The second method,called subtractive,starts with white light(a mixture of all colors in the spectrum)and,by taking away some or all other colors,leaves the one desired.In the additive method,separate colored lights combine to produce various other colors.The three additive primary colors are green,red and blue(each providing about one-third of the wavelengths in the total spectrum).Mixed in varying proportions,they can produce all colors.Green and red light mix to produce yellow,red and blue light mix to produce magenta(a purplish pink);green and blue mix to produce cyan(a bluish green).When equal parts of all three of these primary-colored beams of light overlap（重叠）,the mixture appears white to the eye.In the subtractive process colors are produced when dye（染料）absorbs some wavelengths and so passes on only part of the spectrum.The subtractive primaries are cyan,magenta and yellow; these primaries or dyes absorb red,green and blue wavelengths respectively,thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red,green and blue.Properly combined,the subtractive primaries can absorb all colors of light, producing black.But,mixed in varying proportions,they too can produce any color in the spectrum.Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum,the result looks the same to the eye.The additive process was employed for early color photography. But the subtractive method,while requiring complex chemical techniques,has turned out to be more practical and is the basis of all modern color films. Dreams Everyone can dream. Indeed, everyone does dream. Those who (51)thatthey never dream at all actually dream (52) as frequently as the rest of us， (53)they may not remember anything about it. Even those of us who are perfectly (54) of dreaming night after night very seldom remember those dreams in (55)detail but merely retain an untidy mixture of seemingly unrelated _ (56),Dreams are not simply visual — we dream with all our (57)so that we appear to experience sound, touch, smell, and taste.

Archimedes was a famous Greek mathematician and scientist. He was born around 287 B.C. and he died in the year 212 B.C..　　Archimedes is most well-known for one specific idea that he came up with. “Archimedes"s Principle” states that a solid object which is in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more.　　It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.A good title for the selection is ____.（　　）
