Children in America like Halloween very much.
On the 31st of October, they put on special clothes in the evening. Sometimes they dress like witches (女巫) and ghosts (幽灵). Sometimes they dress like kings and queens. They go to their neighbours’ houses and knock at the doors. The neighbours open the door. The children say, “Trick or treat?” And the neighbours give them some sweets.
Sometimes people don’t give the children any food. Then they play a trick on them. They may put soap (肥皂) on their windows.
