On what holiday do you go trick-or-treating?
A trick is an action that is intended to fool or deceive someone. 捉弄; 诡计
If you treat someone to something special which they will enjoy, you buy it or arrange it for them. 款待
Trick-or-treating typically happens between 5:30pm and 9:30pm on October 31, although some municipalities choose other dates. Homeowners wishing to participate sometimes decorate their homes with artificial spider webs, plastic skeletons and jack-o-lanterns. While not every residence may be decorated for the holiday, those participating in the handing out of candy will opt to leave a porch light on to signify that the opportunity for candy is available.
The origin of Halloween
The origin of Halloween can be traced back to the Celts, a tribe that resided in Ireland and Northern France. The Celts’ lives were dependent upon farming and thus, they worshipped nature. The Celts were superstitious. They believed that the winter season brought death. The last day of October marked the end of summer because November was the beginning of winter.
The Celts celebrated the last day of October and believed the dead would visit them, so they left food and drink outside their homes for the spirits of the dead. Halloween is thought to have originated around 4000 B.C., which means Halloween has been around for over 6,000 years!
