Everyone has heard of the San Andreas fault (断层), which constantly threatens California and the West Coast with earthquakes. 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 destroyed.
Whole forests fell at once, and huge cracks opened in the ground, allowing smell of sulfur (硫磺) 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 earthquakes 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 (倾斜) forward.
The New Madrid fault, on the other hand, is a vertical fault; a 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 (触发) 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 lllinois.
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 the scientists say have no method of predicting when a large earthquake will occur.
This passage is mainly about_____.
A．the New Madrid fault in Missouri
B．the San Andreas and the New Madrid faults
C．the causes of faults
D．current scientific knowledge about faults

31. This passage is mainly about ______.

Geologists would like to be able to predict earthquakes accurately. Using laser beams, seismographs, gravity-measuring devices, and radio telescopes, they are presently studying the San Andreas Fault to determine the rate of strain and the amount of ground slippage. Calculations indicate that sometime within the next ten years, California will be struck by a major earthquake.
In spite of the geologists' theory of plate tectonics, there are still gaps in man's understanding and knowledge of the causes of earthquakes. Powerful earthquakes have occurred in places where plate boundaries are hundreds of miles away. In the 1800s, New Madrid, Missouri and Charleston, South Carolina, were shaken by earthquakes that no one had foreseen.
Certain areas of the world are quake prone. Italy, Yugoslavia, and Algeria have experienced many quakes. In November 1980, Naples was struck by an especially devastating quake. China and Japan have also been hit by horrendous quakes. In 1923, Tokyo and Yokohama were reduced to rubble by gigantic tremors that were followed by fires, tornadoes, and finally a thirty-four-foot tsunami, or tidal wave, which was caused by the earth's drop into the waters of Tokyo Bay. More than 150,000 people died in that earthquake.
What effects have geologists' predictions of earthquakes had？ The Chinese in Haicheng in 1974 were warned that an earthquake might occur within the next year or two. With the help of amateur seismologists' observations of animal behavior. and the rise and fall of water in wells and measurements of quantities of radioactive gas in water, professional geologists were able, in January 1975, to predict an earthquake within the next six months. On February 4, Haicheng was destroyed, but because its residents have been evacuated, very few people were killed. In California, where earthquake is an ever present menace, building codes now require quakeproof structures, and Civil Defense units have intensified their training in how to deal with disaster should it strike or, perhaps more accurately, when it strikes. Should predictions of a quake within the next ten years be accurate, many Californians may be able to save both their lives and their property.

Few football grounds boast a more prestigious

Real (royal) prefix. Work began on the current
stadium in October 1944. The land had been purchased
on three million pesetas; construction costs totalled a 【M5】______
further 38 million, a staggered sum for the time. The 【M6】______
cost of the new stadium led to claims, never proving, 【M7】______

Real Madrid became the greatest club side ever, won 【M8】______
the European Champions Cup a record five times in a
