答案
Halloween
Halloween is an autumn holiday that Americans celebrate every year.It means "holy evening," and it comes every October 31,the evening before All Saints' Day.However,it is not really a church holiday,it is a holiday for children mainly.
Every autumn,when the vegetables are ready to eat,children pick large orange pumpkins.Then they cut faces in the pumpkins and put a burning candle inside.It looks as if there were a person looking out of the pumpkin!These lights are called jack-o'-lanterns,which means "Jack of the lantern".
