6、、第二部分:阅读判断(第 1622 题,每题(总题数:1,分数:7.00)Eastern Quakes Can Trigger Big Shakes In the first week of November 2011, people in central Oklahoma experienced more than two dozen earthquakes. The largest, a magnitude 5.6 quake, shook thousands of fans in a college football stadium, caused cracks in a few bui
7、ldings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV, you see reports about all sorts of natural disasters hurricanes, tornadoes, flooding and wildfires, to name a few. But the most d
8、angerous type of natural disaster, and also the most unpredictable, is the earthquake. Researchers at the U.S. Geological Survey estimate that several million earthquakes rattle the globe each year. That may sound scary, but people dont feel many of the tremors because they happen in remote and unpo
9、pulated regions. Many quakes happen under the ocean, and others have a very small magnitude, or shaking intensity. A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011, was felt from central Georgia to southeastern Canada. In many urban areas, including Washington
10、, D.C., and New York City (Wall Street shown), people crowded the streets while engineers inspected buildings. Credit: Wikimedia/Alex Tabak Scientists know about small, remote quakes only because of very sensitive electronic devices called seismometers. These devices detect and measure the size of g
11、round vibrations produced by earthquakes. Altogether, USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year. Although earthquakes can happen anywhere in the world, really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher a
12、nd happen, on average, only once each year. Such big ones typically occur along the edges of Earths tectonic plates. Tectonic plates are huge pieces of Earths crust, sometimes many kilometers thick. These plates cover our planets surface like a jigsaw puzzle. Often, jagged edges of these plates temp
13、orarily lock together. When plates jostle and scrape past each other earthquakes occur. On average, tectonic plates move very slowly about the same speed as your fingernails grow. But sometimes earthquakes rumble through portions of the landscape far from a plates edges. Although less expected, thes
14、e “mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centuries ago. Today, scientists are still puzzling over why the quakes occurred and when similar ones might occur. (分数:7.00)(1). Oklahoma is an area often experienci

18、s. The Greek philosophers believed that light was made up of countless, tiny particles that enter the human eye and create what we call vision. However, Empedocles and a Dutch scientist named Christian Huygens believed that light was like a wave. According to them, light spread out and travelled lik
19、e a straight line. This theory was accepted during the 19th century. 2 ln 1905, Albert Einstein published a research paper in which he explained what is referred to as the photoelectric effect. This theory explains that particles make up light. The particles Einstein was referring to are weightless
20、bundles(束)of electromagnetic(电磁)energy called photons(光子). Today, scientists agree that light has a dual(二重) nature it is part particle and part wave. It is a form of energy that allows us to see things around us. 3 Things that give off light are known as sources of light. During the day, the primar
21、y source of light is the sun. Other sources of light include stars, flames, flashlights, street lamps and glowing gases in glass tube. 4 When we draw the way light travels we always use straight lines. This is because normally light rays travel in a straight line. However, there are some instances t
22、hat can change the path and even the nature of light. They are reflection, absorption, interference (干扰), etc. 5 Physicists have attempted to measure the speed of light since the early times. In 1849, Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror located kilometer
23、s away and placed a rotating cogwheel(旋转齿轮)between the beam and the mirror. From the rate of rotation of the wheel, number of wheels teeth and distance of the mirror, he was able to calculate that the speed of light is 313 million meters per second. In a vacuum(真空),however, the speed of light is 299
24、,792,458 meters per second. This is about a million times faster than the speed of an airplane. 23. Paragraph 2 _ 24. Paragraph 3 _ 25. Paragraph 4 _ 26. Paragraph 5 _ A. How is the nature of light explained today? B. What are sources of light? C. How did physicists measure the speed of light? D. Ho
