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 buildings 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 dangerous type of natural disaster, and also the most unpredictable, is the earthquake.

Researchers at the U.S. Geological Survey (USGS) estimate that several million earthquakes rattle the globe each year. That may sound scary, but people don’t feel many of the tremors because they happen in remote and unpopulated regions. Many quakes happen under the ocean, and others have a very small magnitude, or shaking intensity.

Scientists know about small, remote quakes only because of very sensitive electronic devices called seismometers. These devices detect and measure the size of ground 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 and happen, on average, only once each year. Such big ones typically occur along the edges of Earth’s tectonic plates.

Tectonic plates are huge pieces of Earth’s crust, sometimes many kilometers thick. These plates cover our planet’s surface like a jigsaw puzzle. Often, jagged edges of these plates temporarily 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 plate’s edges. Although less expected, these “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.

16. Oklahoma is an area often experiencing natural disasters.

A. Right A. Right A. Right A. Right A. Right A. Right

B. Wrong B. Wrong B. Wrong B. Wrong B. Wrong B. Wrong

C. Not mentioned C. Not mentioned C. Not mentioned C. Not mentioned C. Not mentioned C. Not mentioned

17. The earthquake is the most unpredictable natural disaster. 18. Few earthquakes happen without people's awareness.

19. Seismometers can identify and locate most of the earthquakes in China.

20. Big earthquakes of a magnitude 8 or higher seldom happen far from the edges of tectonic plates. 21. Whenever tectonic plates move, earthquakes happen.

22. The earthquake that hit the eastern half of the United States two centuries ago is the biggest \one in history.

A. Right

B. Wrong

C. Not mentioned

Learn about Noble Gases(惰性气体)

2

1 Have you ever ridden on a balloon? Many tourist spots offer balloon rides in order for people to see the beauty of a place from above. A balloon contains a noble gas called hellum(氦). Formerly, balloons contained hydrogen but hydrogen is very flammable and dangerous when uncontrolled. Therefore, people shifted to helium, which is safer. Helium is safe because it has the properties of the noble gases.

2 People once believed that noble gases couldn’t chemically react at all. For this reason, they were called inert gases(惰性气体). They were also listed under Group 0 in the old periodic table because scientists believed that the gases have zero valence(价)electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.

3 The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, and having low chemical reactivity. Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon. These are all found in Group 18, in the rightmost column of the periodic table. If you look at the periodic table, you will notice that these elements are the only ones, which do not have a charge. Helium has the lowest molecular(分子的)weight while Radon is the heaviest.

4 Remember that chemical reactions occur because atoms have valence electrons, which are electrons in their outer shell. When the outer shell is “unfilled” or the required number of electrons is not yet complete, the atom is more reactive. Noble gases have a full outer shell, meaning that they have complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble gases because of the low chemical reactivity of these said gases.

5 because of their properties, noble gases have many important applications. They are widely used in

medicine and industries. For instance, liquid Helium is used for superconducting magnets(磁体). These magnets are very important in physics and medicine. When a doctor suspects that a person’s brain has been damaged, he might request for Magnetic Resonance Imaging (MRI). MRI allows the doctor to “see” the brain, without operating on the patient.

23. Paragraph 2__________. 24. Paragraph 3__________. 25. Paragraph 4__________. 26. Paragraph 5__________.

A What are noble gases? B What is the periodic table? C What causes the low chemical reactivity of noble gases? D How were noble gases discovered? E How were noble gases discovered? F：What are the applications of noble gases? 27 Noble gases are not very chemically___ ．

A lightest 28 Among the elements of noble gases Helium is the_ .

B reactive 29 The required number of electrons in noble gases’ outer shell is ．

C important 30 MRI may make operating on the patient ．

D complete

E flammable

F unnecessary
