万圣节的活动及故事，要英文的！

On October 31st, dozens of children dressed in costumes（节日服装）knock on their neighbors' doors and yell "Trick or Treat" when the door opens. Pirates and princesses, ghosts and popular heroes of the day all hold bags open to catch the candy or other goodies that the neighbors drop in. As they give each child a treat the neighbors exclaim over the costumes and try to guess who is under the masks.

Halloween (also spelled Hallowe'en) is a holiday celebrated on October 31. It has roots in the Celtic festival of Samhain and the Christian holy day of All Saints’ Day. It is largely a secular celebration, but some Christians and pagans have expressed strong feelings about its religious overtones.[1][2][3] Irish immigrants carried versions of the tradition to North America during Ireland's Great Famine of 1846.[4] The day is often associated with the colors orange and black, and is strongly associated with symbols such as the jack-o'-lantern.
