Most earthquakes occur within the upper 15 miles of the earth's surface. But earthquakes can and do occur at all depths to about 460 miles. Their number 【C1】______as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as【C2】______as 100 in a month, but the yearly average does not vary much.
The【C3】______of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set, it will still stand no matter how【C4】______you shake the table. But if you build a toy house with a(n) 【C5】______of cards, a slight shake of the table will make it fall. An earthquake in Agadir, Morocco, was not strong enough to be recorded on distant instruments, but it completely destroyed the city. Many stronger earthqua
kes have **paratively【C6】______damage. If a building is well constructed and built on solid ground, it will【C7】______an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building【C8】______. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.

2020英语四级考试时间Abraham Lincoln turns 200 in 2009, and he's beginning to show his age. When his birthday arrives, on February 12, Congress will hold a special joint session in the Capitols National Statuary Hall, a wreath will be laid at the great memorial in Washington, and a(n)【C1】______will link school classrooms for a "teach-in" 【C2】______his memory.
Admirable as they are, though, the events will strike many of us Lincoln fans as【C3】______, even halfhearted, and another sign that our appreciation for the 16th president and his【C4】______achievements is slipping away. And you don't have to be a Lincoln enthusiast to believe that this is something we can't afford to lose.
Compare this year's celebration with the Lincoln【C5】______, in 1909. That year, Lincoln's likeness【C6】______its debut on the penny, thanks to approval from the U.S. Secretary of the Treasury. Communities and【C7】______associations in every corner of the country erupted in parades, concerts, balls, lectures, and military displays. We still feel the effects today: The momentum unloosed in 1909 led to the Lincoln Memorial, opened in 1922, and the Lincoln Highway, the first paved transcontinental thoroughfare.
