【简答题】
Long long ago people made fires from lightning(闪电)。 But they had to keep the fire burning, for they couldn’t start it again if there was no lightning. Later, they found out hitting two piece 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. Them people also learned to make a fire by rubbing. They made a hole on a big 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 ways to make a fire. Sometimes they used the heat from 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 (火柴). Matches brought people a quick and easy way to make fire. 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 than a box of matches. But it is more useful. 小题1:A spark can _________.
