On Nov.18th, 1908, three men went up in a balloon. They started early in London. The headman was Auguste Gaudron, and the other two men were Tannar and Maitland. They had a big balloon and they were ready for a long way.

Soon they heard the sea. They were carrying the usual rope, and it was hanging down from the basket of the balloon. At the end of the rope they had tied a metal box. This could hold water, or it could be empty. So they were able to use the box to change the weight of the balloon. The three people were also carrying some bags of sand.

After the sun rose, the balloon went higher. It went up to 3,000 metres, and the air was very cold. The water in the balloon became ice. Snow fell past the men's basket, and they could see more snow on the ground. The men tried to throw out some more sand; but it was hard. They tried to break the icy sand with their knives, but it was not easy. The work was slow and they were still falling, so they had to drop some whole bags of sand. One of them fell on an icy lake and made a black hole in the ice.

　　At last they pulled the box into the basket. It was still snowing; so they climbed to get away from the snow. They rose to 5,100 metres! Everything became icy. They were very cold and  they decided to land. They came down in Poland　heavily but safely. They had travelled 1,797 kilometres from London!

　　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?”
