A. 8:30 to 11:30 on Sunday B. 19:00 to 21:00 on Monday C. 19:30 to 21:00 on Wednesday D. 18:30 to 21:00 on Friday B The Kingdome in Seattle was destroyed on March 26, 2000. It was taken down to make room for a new stadium. The blast(爆破) from the falling building caused the earth to shake as if an earthquake had happened. Scientists placed more than 200 earthquake recorders in the earth to measure the movement. They found which parts of the city shook the most. This information helped them know which parts of the city would be damaged in a real earthquake at an early time. A real earthquake happened on February 28, 2001 in Seattle. The Nisqually earthquake was 6.8 on the Richter scale(里氏6.8级). It damaged the same parts of Seattle that scientists had predicted(预测) from the pulling down of the Kingdome. It was a plate quake. It started deep in the earth, 37 miles below the surface on the Juan de Fuca Plate. Sometimes, huge plates under the earth cause earthquakes when the plates move against each other suddenly. Scientists have learned that deep earthquakes have very few aftershocks(余震). The Nisqually earthquake had only 4 ones. Another earthquake in California that was close to the surface had over 120 aftershocks. Scientists do not know why the deep earthquakes have fewer aftershocks. Scientists plan to blast in the ground near Seattle with the purpose of testing the plate. The shockwaves from the blast will jump off the plate and give them an idea of where the plate is and how it is moving. This will give them more information in case another real earthquake hits the area. 45. According to the passage, ______ have the most aftershocks. A. shockwave earthquakes B. shallow earthquakes C. deep earthquakes D. earthquakes more than 6.8 Richter scale 46. What do scientists hope to learn from the blast above the Juan de Fuca Plate? A. They hope to learn where the plate is and how it is moving. B. They want to destroy the Kingdome. C. They want to know which places are likely to have the most damage. D. They hope to find out how many plates there are in the ground there. 47. Why were the scientists interested in the pulling down of the Seattle Kingdome? A. They wanted to see which areas near the Kingdome would shake the hardest. B. They wanted to predict what might happen in a real earthquake. C. They wanted to measure the movement of the Earth with earthquake recorders. D. All of the above. 48. What will happen after a deep earthquake according to the scientists? A. There will be many aftershocks. B. There will be very few aftershocks. C. The Richter scale of the quakes will be a 6.8 or more. D. There will be little damage. C On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man. The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever. Soon he was surrounded with people who were attracted by the words on that paper. It said, “Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim (认领) it soon.” After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, “Yes, it’s you. I knew that you were an honest man and would certainly come here.” The young violinist asked calmly, “Are you Mr George Sang?” The man nodded. The violinist asked, “Did you lose something?” “It’s a lottery ticket,” said the man. The violinist took out a lottery ticket on which George Sang’s name was seen. “Is it?” he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist. The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, “At that time you needed money to pay the tuition and you had to play the violin in the railway station every day to make money. Why didn’t you keep the lottery ticket for yourself?” (责任编辑：admin) |
