e was not allowed into heaven when he died, because he was a miser（吝啬鬼）。 He couldn't enter hell either because he had played jokes on the devil. As a result, Jack had to walk the earth with his lantern until Judgement Day（审判日）。 The Irish people carved scary faces out of turnips（芜菁根）， beets（甜菜根）or potatoes representing Jack of the Lantern, or Jack-o'lantern. When the Irish brought their customs to the United States, they carved faces on pumpkins because in the autumn they were more plentiful than turnips. Today jack-o'-lanterns in the windows of a house on Halloween night let costumed children know that there are goodies（糖果）waiting if they knock and say Trick or Treat!
