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一 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 estimate that several million earthquakes rattie 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.
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,
D.
C.,and New York City(Wall Street shown),people crowded the streets while engineers inspected buildings.
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一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.
Seismometers can identify and locate most of the earthquakes in China.

[单项选择]
To broaden their voting appeal in the presidential election of 1796, the Federalists selected Thomas Pinckney, a leading South Carolinian, as framing mate for the New Englander John Adams. But Pinckney’ s Southern friends chose to ignore their party’ s intentions and regarded Pinckney as a presidential candidate, creating a political situation that Alexander Hamilton was determined to exploit. Hamilton had long been wary of Adams’ stubbornly independent brand of politics and preferred to see his running mate, over whom he could exert more control, in the President’s chair.
The election was held under the system originally established by the Constitution. At that time there was but a single tally, with the candidate receiving the largest number of electoral votes declared President and the candidate with the second largest number declared Vice-President. Hamilton anticipated that all the Federalists in the North would vote for Adams and Pinckney equ

B. South Carolina’ s loyalty to Thomas Pinckney
C. Private contact with state officials urging them to support Thomas Pinckney
D. John Adams’ reputation as a stubborn and independent New Englander
