As water flows along the ground, it picks up sand, pebbles, even boulders. It uses them to gnaw at the sides and bottom of its channel, gradually loosening more earth.
By this process enormous amounts of mud and rock are moved from the land to the sea. Each year the Mississippi River carries 730 million tons of solid matter into the Gulf of Mexico.
This constant hauling of land into the sea is lowering the United States’ average height above sea level at a rate of about one foot every 9000 years. If erosion continues at the same rate, the United States will be worn completely down to sea level in about 23 million years.

One of the most basic moral values for Americans is honesty. The wall-known legend about George Washington and a cherry tree teaches this value clearly.
Another virtue Americans respect is perseverance. Remember Aesop’s fable about the turtle and the rabbit that had a race The rabbit thought he could win easily, so he took a sleep. But the turtle finally won because he did not give up.
Compassion(同情心)may be the queen of American virtues. In 1992, people in Iowa sent truckloads of water to help Floridians hit by a hurricane. The next summer, during the mid-west of flooding, Florida returned the favor.
