8 第三部分阅读理解（共20小题；每小题2分，满分40分） A Experts around Europe are discussing the embarrassing museum safety following the theft of two art masterpiece paintings on Sunday. A large hunt got under way Monday for thieves who walked into a lightly guarded museum in Oslo, Norway, tore two paintings off the wall and ran away. Some expressed fear that works of art are in increasing danger from violent robbery — unless, said Deputy Culture Minister Yngve Slettholm, "we lock them in a mountain bunker(碉堡)." Armed, masked robbers stole the Edvard Munch masterpiece "The Scream" and another of Munch"s works, "Madonna," from Oslo"s Munch Museum on Sunday as visitors watched in disbelief. The purpose behind the robbery also remained unknown. But art experts guessed the thieves were either looking for money or wished to impress other criminals since it would be nearly impossible to sell such famous pieces of art. This is the second time in a decade that a version of the painting has been stolen. Another version of "The Scream" was stolen from Oslo"s National Gallery in February 2004, but recovered three months later. The Munch works were not insured against theft, because it was impossible to set a price on them, said John Oeyaas, managing director of Oslo Forsikring, the city-owned company that insured the paintings against damage. But he said the theft in broad daylight from one of Norway"s most visited museums raises the question of security — "How can we make these artworks available to the public while still ensuring their safety?" 56. The stolen paintings were drawn by ______. A. Oslo Forsikring B. Yngve Slettholm C. Edvard Munch D. John Oeyaas 57.Which of the following description is correct about the theft? A.The two paintings were stolen on Monday B.Visitors to the museum saw the faces of the robbers C.The thieves were looking for money D.The thieves had weapons with them during the theft 58. The Oslo’s Munch Museum ______. A.is one of the most popular museum in the country B.had all its paintings insured against theft C.were going to lock the paintings in a mountain bunker D.had another version of “The Scream” stolen in 2004 59. What could be the best title for this passage? A.Dangers of Violent Robbery B.How to Ensure Safety of Artworks C.Priceless Art Lost in Bold Theft D.Famous Art Works Favored by Thieves
