单选题Winners and Losers Why are the biggest winners in the past decade of trade globalization mostly in South and East Asia, whereas the biggest losers are mostly in the former Soviet bloc (集团) and sub-Saharan Africa? History is a partial guide: East Asia has a long trading tradition, lately reinvigorated (给以新的活力) by the Chinese adoption of market economics. The Soviet Union, on the other hand, was sheltered from free-market forces for more than 70 years. In Africa, some countries are disadvantaged because of inadequate infrastructure (基础结构); many countries have little to trade but commodities, the prices of which have fallen in recent years. In some regions, certain countries have suffered by adopting misguided policies, often under pressure from International Monetary Fund. First among these is Russia, which in the early 1990s tried to embrace capitalism before first building the institutions that make capitalism work, such as an independent bank system, a system of business law, and an adequate method for collecting taxes. Encouraged by the I. M. F., the World Bank and the U.S. Department of the Treasury, President Boris Yeltsin's regime privatized the state-owned industrial sector, creating a class of oligarchs (寡头政治集团成员), who, knowing how unstable conditions were at home, sent their money abroad instead of investing it at home. In contrast, China, the biggest winner from globalization, did not follow the I. M. F. formula. Of the former states of the Soviet bloc, only a few, notably Poland and Hungary, managed to grow, which they did by ignoring I. M. F. advice and adopting expansionary plans, including spending more than they collected in taxes. Botswana and Uganda are also success stories, despite their disadvantages, their countries achieved vigorous growth by creating stable civil societies, liberalizing trade and implementing reforms that ran counter to I. M. F. prescriptions.

单选题The Iceman On a September day in 1991, two Germans were climbing the mountains between Austria and Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, or 3,200 meters), the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual and so the body had come to the surface. It was lying face downward. The skeleton (was in perfect condition, except for a wound in the head. There was still skin on the bones and the remains of some clothes. The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots. Nearby was a pair of gloves made of tree bark and a holder for arrows. Who was this man? How and when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before and whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousand years old. With modem dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 BC, he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story. A new kind of X-ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage and bleeding. He almost certainly died from this wound, and not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war, or he may have been fighting bandits. He may even have been a bandit himself. By studying his clothes and tools, scientists have already learned a great deal from the Iceman about the times he lived in. we may never know the full story of how he died, but he has give us important clues to the history of those distant times.
