Trick or Treat 不给糖就捣乱

The custom of Halloween was brought to America in the 1840's by Irish immigrants fleeing their country's potato famine. At that time, the favorite pranks in New England included tipping over outhouses and unhinging fence gates.
The Halloween we celebrate today includes all of these influences, Pomona Day's apples, nuts, and harvest, the Festival of Samhain's black cats, magic, evil spirits and death, and the ghosts, skeletons and skulls from All Saint's Day and All Soul's Day.
The custom of trick-or-treating is thought to have originated not with the Irish Celts, but with a ninth-century European custom called souling. On November 2, All Souls Day, early Christians would walk from village to village begging for "soul cakes," made out of square pieces of bread with currants. A: The more soul cakes the beggars would receive, the more prayers they would promise to say on behalf of the dead relatives of the donors. At the time, it was believed that the dead remained in limbo for a time after death, and that prayer, even by strangers, could expedite a soul's passage to heaven.
孩子们今天着装挨家要糖的习俗，也就是我们所说的Trick or Treat，据说起源于爱尔兰。古西欧时候的爱尔兰异教徒们，相信在万圣节前夜，鬼魂会群集于居家附近，并接受设宴款待。因而，在“宴会”结束后，村民们就自己扮成鬼魂精灵，游走村外，引导鬼魂离开，避邪免灾。于此同时，村民们也都注意在屋前院后的摆布些水果及其他食品，喂足鬼魂而不至于让它们伤害人类和动物或者掠夺其他收成。后来这习俗一直延续下来，就成了孩子们开的玩笑。
