　　President (總統(tǒng)) George W Bush is visiting an elementary school today and visits one of the 4th grade classes. They are in the middle of a discussion(討論) of words and their meanings.

　　The teacher asks the President if he would like to lead the class in the discussion of the word“tragedy”. So the President asks the class for an example of a“tragedy”.

　　One little boy stands up and says,“If my best friend, who lives next door, is playing in the street and a car comes along and runs him over, that would be a tragedy.”

　　“No,”says Bush,“that would be an accident.”

　　A little girl puts up her hand,“If a school bus carrying 50 children drove off a cliff(懸崖), killing everyone in the bus, that would be a tragedy.”

　　“I am afraid not,”explains the President.“That is what we would call a GREAT LOSS(損失).”

　　The room goes quiet. No other children answer. President Bush looks around the mom.“Is not there someone here who can give me an example of a tragedy?”

　　At last, in the back of the room, a boy named Johnny puts up his hand. In a quiet voice he says,“If Air Force One, carrying you and Mrs Bush, was hit by a missile(導彈) and blown up to pieces, that would be a tragedy.”

　　“Right,”exclaims(大叫)Bush,“that is right, and can you tell me why that would be a tragedy?”

　　“Well,”little Johnny says,“because, as you just told us, it would not be an accident, and it sure as well would not be a great loss.”
