单选题Half of the world"s coral reefs(珊瑚礁) have died in the last 30 years. Now scientists are racing to ensure that the rest survive. Even if global warming were to stop fight now, scientists predict that more than 90% of corals will die by 2050. If no major steps are taken to address the problem, the reefs may be headed for total extinction(灭绝). (78) The planet"s health depends on the survival of coral reefs. They are often described as "the rainforests of the sea", because they provide shelter for a wide variety of sea life. In addition, the reefs serve as barriers that protect coastlines from the full force of powerful storms. Coral are used in medical research for cures to diseases. They are key to local economies as well, since the reefs attract tourists, the fishing industry, and other businesses, bringing in billions of dollars. (79) Corals are particularly sensitive to changes in temperature. A rise of just 1 to 2 degrees can force the corals to drive out the algae(水藻). Then the corals turn white in a process called "bleaching". Corals can recover from short-term bleaching, but long-term bleaching can cause permanent damage. In 1998, when sea surface temperatures were the highest in recorded history, coral reefs around the world suffered the most severe bleaching. It is estimated that even under the best of conditions, many of these coral reefs will need decades to recover. Although reefs face other threats from pollution, industrial activities, and overfishing, it is global climate change that most concerns scientists. Scientists remain hopeful that it"s not too late to save the reefs, and some are moving ahead on experiments to accomplish that goal.

单选题A study of art history might be a good way to learn more about a culture than is possible to learn in general history classes. Most typical history courses concentrate on politics, economics and war. But art history focuses on much more than this because art reflects not only the political values of a people, but also religious beliefs, emotions and psychology. In addition, information about the daily activities of our ancestors can be provided by art. In short, art expresses the essential qualities of a time and a place, and a study of it clearly offers us a deeper understanding than can be found in most history books. In history books, objective information about the political life of a country is presented, that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective (主观的): it reflects emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly "political" artist. In his well-known painting The Third of May, 1808, he criticized the Spanish government for its abuse (滥用) of power over people. In the same way, art can reflect a culture"s religious beliefs. For hundreds of years in Europe, religious art had been almost the only type of art that existed. Churches and other religious buildings were filled with paintings that described people and stories from the Bible. Although most people couldn"t read, they could still understand the Bible stories in the pictures on church walls. By contrast, one of the main characteristics of art in the Middle East was (and still is) its absence of human and animal images. This reflects the Islamic belief that statues (雕像) are not holy.
