Albert Szent-Gyorgyi was born in Budapest on September 16, 1893. In 1911 he entered his uncle's laboratory where he studied until the outbreak of World War One, when he joined the army. He served on the Italian and Russian fronts, and he was permitted to leave the army in 1917 after being wounded in action. He completed his studies in Budapest before he went to Hamburg for a two-year course in physical chemistry. In 1920 he became an assistant at a university in Leiden, the Netherlands and from 1922 to 1926 he worked with H. J. Hamburger at the Physiology Institute, Groningen, the Netherlands. In 1926, Szent-Gyorgyi was ready to end his own life after an embarrassing problem in his career. The scientist, thirty-two, had written a paper and handed it to his boss for approval to publish. His boss threw it in the dustbin. Concluding his life was a failure, the young researcher quit. Unable to support his wife and child, he sent them home to her parents. His final wish was to attend one last scientific meeting, to be among scientists, to have one last good time. So he went to the 1926 International Physiological Society Congress in Sweden. Sitting in the audience, lost in self-pity, Szent-Gyorgyi listened to the president of the society, Sir Frederick Gowland Hopkins, refer to the fine work of a researcher: Szent-Gyorgyi! After the speech, collecting his courage, he introduced himself to Hopkins. The great man invited the young scientist to Cambridge to do further work. Szent-Gyorgyi's life changed. He discovered the oxidation-preventing action of vitamin C. He won the Nobel Prize in Physiology or Medicine in 1937. He accounted for his success by saying that discovery is seeing what everyone else has seen but thinking what nobody else has thought. The passage is organized in the pattern of _ . A) cause and effect B) comparison and contrast C) time and events D) definition and classification

Everyone has heard of the San Andreas fault , which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri? Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, releasing some strong smell chemicals. The Mississippi River itself completely changed character, developing sudden rapids and whirlpools . Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Marid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C. Scientists now know that America's two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the two masses make a sudden move. The New Madrid fault, on the other hand, is a vertical fault; at some points, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions cause earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois. Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the... This passage implies that _ . . A) horizontal faults are more dangerous than vertical faults B) Vertical faults are more dangerous than horizontal faults C) The volcanoes that caused the New Madrid fault are still alive D) A lot of people would die if the 1811 New Madrid earthquakes happened today

*Question*
Is any economist so dull as to criticise Christmas? At first glance,the holiday season in western economies seems a treat for those concerned with such vagaries as GDP growth.After all,everyone is spending;in America,retailers make 25% of their yearly sales and 60% of their profits between Thanksgiving and Christmas.Even so,economiwsts find something to worry about in the nature of the purchases being made. Much of the holiday spending is on gifts for others.At the simplest level,giving gifts involves the giver thinking of something that the recipient would like-he tries to guess her preferences,as economists say-and then buying the gift and delivering it.Yet this guessing of preferences is not easy;indeed,it is often done badly.Every year,ties go unworn and books unread.And even if a gift is enjoyed,it may not be what the recipient would have bought if they had spent the money themselves. Interested in this mismatch between wants and gifts,in 1993 Joel Waldfogel,then an economist at Yale University,sought to estimate the difference in dollar terms.In a research,he asked students two questions at the end of a holiday season:first,estimate the total amount paid (by the givers) for all the holiday gifts you received;second,apart from the sentimental value of the items,if you did not have them,how much would you be willing to pay to get them? His results were gloomy:on average,a gift was valued by the recipient well below the price paid by the giver. In addition,recipients may not know their own preferences very well.Some of the best gifts,after all,are unexpected items that you would never have thought of buying,but which turn out to be especially well picked.And preference can change.So by giving a jazz CD,for example,the giver may be encouraging the recipient to enjoy something that was ignored before.This,a desire to build skills,is possibly the hope held by many parents who ignore their children's desires for video games and buy them books instead. Finally,there are items that a recipient would like to... According to the text,which of the following statements is TRUE? A) Price is nothing but the factor when you give gifts. B) Chocolates will be blamed when people receive them as gifts. C) The receivers often overestimate the values of gifts. D) Wants do not always correspond to needs in gift-giving.
