It was first celebrated in Ireland and Scotland as a festival of the dead. Families invited their ancestors (祖先) into their homes but tried to keep bad spirits (精灵) out by wearing scary costumes (服装). Now the holiday is a time for fun and excitement. Families carve (雕刻) scary or funny faces into pumpkins and put candles inside to make them into lanterns (灯笼). These are called jack-o''-lanterns. Children dress up in costumes and walk around their neighborhoods collecting candy. They knock on doors and when a person opens the door, the children shout, “Trick or treat!” Once, this meant that if the person at the door did not give the children a treat, they would play a mean (坏的) trick. But today, children usually do not play tricks. They are too busy getting as much candy as they can!
