Text 3Everyone has heard of the San Andreas fault, which constantly threatens California and the West Coast with earth- quakes. But how many people know about the equally serious New Madrid fault in Missouri.'?Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe.Buildings in the area were almost dest oyed. Whole forests fell at once, and huge cracks opened in the ground, allowing smell of sulfur to filter upward.The Mississippi River itself completely changed character, developing sudden rapids and whirlpools. Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Madrid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earth- quakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington D.C. Scientists now know that America's two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the movement of these two masses suddenly lurches forward.The New Madrid fault, on the other hand, is a vertical fault; at some point, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now', the rock continues to settle downwards, and sudden sinking motions trigger earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois.Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but rite scientists say they have no method of predicting when a large earthquake will occur.31. This passage is mainly about ______.A) the New Madrid fault in MissouriB) the San Andreas and the New Madrid faultsC) the causes of faultsD) current scientific knowledge about faults
考题
The New Madrid fault is______.A) a horizontal faultB) a vertical faultC) a more serious fault than the San Andreas faultD) responsible for forming the Mississippi River

Text 4The U.S. government has recently helped people learn more about the dangers of earthquakes by publishing a map. This map shows the chances of an earthquake in each part of the country. The areas of the map where government is spending a great deal of money and is working hard to help discover the answer to these two questions:1. Can we predict earthquakes?2. Can we control earthquakes?To answer the first question, scientists are looking very closely at the most active fault systems in the country, such as the San Andreas fault in California. A fault is a break between two sections of the earth's surface. These breaks between sections are the places where earthquakes occur.Scientists look at the faults for changes which might show that an earthquake was about to occur. But it will probably be many years before we can predict earthquakes accurately and the control of earthquakes is even farther away.Nevertheless, there have been some interesting developments in the field of controlling earthquakes. The most interesting development concerns the Rocky Mountain Arsenal earthquakes. Here water was pat into a layer of rocks 4,000 metres below the surface of the ground. Shortly after this injection of water, there was a small number of earthquakes. Scientists have decided that the water which was injected into the rocks worked like oil on each other. When the water" oiled" the fault, the fault became slippery and the energy of an earthquake was released.Scientists are still experimenting at the site of these earthquakes. They have realized that there is a connection between the injection of the water and the earthquake activity. They have suggested that it might be possible to use this knowledge to prevent very big, destructive earthquakes, that is, scientists Could inject some kind of fluid like water into faults and change one big earthquake into a number of small, harmless earthquakes.36. Earthquake belts are ______.A) maps that show where earthquakes are likely to occurB) zones with a high probability of earthquakesC) breaks between two sections of the earth's surfaceD) the two layers of earth along a fault
考题
What did scientists learn about earthquakes at the Rocky Mountain Arsenal?A) They occur at about 4,000 metres below ground level.B) The injection of water into earthquake faults prevents earthquakes from occurring.C) They are usually caused by the oil in the faults.D) Harmful earthquakes earl be possibly prevented by causing small, harmless earthquakes.

Study Helps Predict Big Mediterranean Quake1.Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.2.Using radiocarbon dating techniques,simulations and computer models,the researchers recreated the ancient disaster in order to identify the responsible fault."We are saying there is probably a repeat time of 800 years for this kind of earthquake,"said Ms Beth Shaw,an earthquake scientist at the University of Cambridge,who led the study. Scientists study past earthquakes in order to deter-mine the future possibility of similar large shocks.3.Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region,Ms.Shaw said.The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years,she added in a telephone interview.4.Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion,she said.Their computer model suggested an 8 magnitude quake on the fault would pro-duce a tsunami that floods the coastal regions of Alexandria and North Africa,the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik.This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta likely killing tens of thousands of people,she said. Ms.Shaw measured the movement of either side of the fault to identify the magnitude of the earthquake taking place in AD 365.A:Right B:Wrong C:Not mentioned

A Great Quake Coming?Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's bound to happen someday. At least seven active fault（断层）lines run through the San Francisco area. Faults are places where pieces of Earth'S crust（地壳）slide past each other.When these pieces slip,the ground shakes.To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre- diet how bad the damage might be when the next one happens.One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the time. During small earthquakes,faults rupture（断裂）at about 2.7 kilometers per second. During bigger quakes,however.ruptures can happen at rates faster than 3.5 kilometers per second.At such high speeds,massive amounts of pressure build up,generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses（脉冲）traveled away from the city during the 1906 event.As bad as the damage was,it could have been far worse.Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data, however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62percent.New buildings in San Francisco are quite safe in case of future quakes.Still,more than S4 percent of the city’s buildings are old and weak.Analyses suggest that another massive earthquake would cause extensivedamage.People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while.According to the new research,however,it's not a matter of"if" the Rig One will hit.It',just a mat-ter of when.A major earthquake striking San Francisco someday is inevitable.A:RightB:WrongC:Not mentioned
