Long,long ago people made the first lightening(闪电).But they had to keep the fire burning,for they couldnt start it again if there was no lighting.Later,they found out hitting two pieces of stone together could make a spark(火花).The spark could fire dry leaves.In this way they could make the fire again if it went out .Then people also learned to make a fire by rubbing(摩擦).They made a hole on a piece of wood and put a smaller stick into the hole. They turned the stick again and again.After a few minutes they got a fire.

As years went by, people learned other way to make a fire.Sometimes they used the heat from the sun.They held a piece of glass in the right way and made a piece of paper on fire.

About two centuries ago, people began to make matches.Matches brought people a quick and easy way to make fires.Today matches are still being used, but people have more new ways to make fires.One of them is to use an electric fire starter.Of course an electric fire starter is much more expensive then a box of matches, But it is very useful.

A.fire and leaves
