To extinguish （熄灭）different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable （手提式的）kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.
Since fuel（燃料）, oxygen and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
The method that is used to put out a fire depends on the type of fire. Fires have been grouped in three classes（级别）. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.

The crowd cheered and cheered. The man with the horn（号）waved and smiled his great smile. “More! More!” cried the crowd. And Louis Armstrong took his horn and began to play again.
Here he was in England. Now a famous man, he was rich. He knew many important people. Wherever he went, people knew his name. They wanted to hear his music. As he played the sad, slow songs, Louis thought of his home in New Orleans. He lived there as a boy. It was a busy, exciting city. But Louis’s family was very poor. He went to work to help his mother. He also went to school. One of Louis’s teachers asked him to join the school band. “This horn is yours until you leave our school,” his teacher said. Louis’s music was jazz and he loved it. He remembered all the music he heard. He didn’t learn to read music until he was a man.
When he left school, he played on many bands. He loved his work and people loved him. They knew that he had a wonderful talent. Louis played in little towns and in big cities. Armstrong’s horn had as many sounds as ten horns—sometimes slow and sometimes sweet; sometimes fast and hot, high and low. His music was always strong and exciting. “He does make wonderful music,” said the man who listened happily. “Yes,” said another man, “he makes that horn speak. ”
The music ended and the crowd cheered. Louis Armstrong spoke with tears in his eyes, “I think, my friends, you can listen to as much jazz as I can play. I thought jazz was my music; but now I understand it is ours. It is beautiful that music brings us together. ”

Air travel is such an everyday experience these days that we are not surprised when we read about a politician having talks with the Japanese Prime Minister one day, attending a meeting in Australia the following morning and having to be off at midday to sign a trade agreement in Hong Kong.
