To begin with, moral values in America are like those in any culture. But the stories and traditions that teach them are unique to each culture. Not only that, but culture has an effect on how people show these virtues. 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. There are more moral values honored by Americans. Courage, responsibility, loyalty, gratitude and many others could be discussed. But no matter how long or short the list is, moral values are invaluable. They are the foundation of American cultures--and any culture.
