Fire can help people in many ways. But it can be very dangerous. Fire can heat water, warm houses, give light and cook. But fire can burn things, too. It can burn trees, houses, animals or people. Sometimes big fire can burn forests.
Nobody knows for sure how people began to use fire. But there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope (绳子) and brought fire down.
Today people know how to make a fire with matches (火柴). Children sometimes like to play with them. But matches can be very dangerous. One match can burn a piece of paper, and then it might burn a house. A small fire can become a big fire very fast. Fire kills many people every year. So you must be careful with matches. You should also learn to put fires. Fires need oxygen (氧气). Without oxygen they will die. Cover a fire with water, sand or sometimes with your coat. This keeps the air away from a fire and kills it. Be careful with fire, and it will help you. Be careless with fire, and it will burn you.

There at a secondhand clothing store in Northampton Mass, my l4-year-old son, John, and I noticed the coat. While the other coats drooped (低垂), this one looked as if it were   41  itself up. The coat was beautifully made, with a Fifth Avenue label and an  42   price of $28, which was popular just then with   43  , but could cost several hundred dollars new. John tried it on and the  44   was perfect.

John  45   the coat to school the next day and came home with a big smile. “Did the kids like your coat?” I asked. “They loved it,” he said,   46   folding it over the back of a chair and smoothing it flat. Over the next few weeks, a   47  came over John. Agreement replaced contrariness (作对) and   48   discussion replaced fierce argument. He became more mannerly and  49  , eager to please. He would generously lend his younger brother his tapes and lecture him   50   his behavior. When I mentioned this   51  to his teacher and wondered what caused the changes, she said laughing. “It   52   be his coat!” Another teacher told him she was giving him a good mark not only because he had earned   53   but because she liked his coat. At the library, we ran   54  a friend. “Could this be John?” he asked surprisingly,   55  John’s new height, appreciating the cut of his coat and holding out his hand, one gentleman to another.

John and I both know we should never   56   a person’s clothes for the real person within them.   57  , there is something to be said for wearing a standard of excellence for the world to see and for   58  what is on the inside with what is on the outside.

For John, it is a time when it is as easy to try on different  59  to life as it is to try on a coat. The whole world, the whole future is stretched out ahead, a vast landscape   60  all the doors are open. And he could picture himself walking through those doors wearing his wonderful, magical coat.
