　　President (总统) 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(讨论) 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(悬崖), 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(损失).”

　　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(导弹) 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.”

I have to See Another Doctor

　　Mr. Clarke lives at the foot of the mountain. He keeps the forest for a rich farmer there. The only road to the forest is just in front of his house. He can easily see the people who want to enter the forest. Sometimes he has to be on duty at night. When he hears some sound, he has to get up to see if someone cuts the trees.

　　One day he bought something in the town. He found a strong dog and bought it. He loves it very much and often gives some meat or bread to it. And when a strange man walks close to his house, it barks (吠) loudly. So he can soon know about it and goes out to find out who it is. But last week something was wrong with Mr. Clarke. He didn't feel well and couldn't fall asleep in the evening. He had to go to a hospital in the town. The doctor looked him over and then asked, “Have you got a dog, sir?”

　　“Yes, I have got one.”

　　“You have got a skin disease (皮肤病),” said the doctor. “I am sure your dog infected (传染) it to you. You can't come in touch with it any longer.”

　　When he came out of the hospital, he met a friend and told him about it. The man asked, “What are you going to do, to sell your dog or to give it to another man?”

　　“Neither,” answered Mr. Clarke, “I have decided to see another doctor. It's much easier to find a doctor than to buy a good dog!”
