介绍： Hello,everyone!Today is the All Saints Day.Now let me present you an article from BBC News.All Saints Day,also known as the Halloween, is one of the most popular festival in western world.So,what is its origin?One of the most interesting things about it is that nobody knows for sure where it came from.It is widely recognised as an American holiday, but it is believed that the tradition of Halloween actually dates back to Britain many centuries ago, with its roots in an Iron Age Celtic festival called Samhain - although there are historians who dispute this.Samhain (a Celtic language word which means 'summer's end') marked the end of the harvest season and the beginning of winter.It is said that, at that time of the year, ghosts came back to visit the living and that the barrier between the two worlds - the living world and the spirit world - was thinner, so spirits could cross it.While people expected some ghosts and didn't mind their visit, they feared the presence of evil spirits and disguised themselves using scary costumes. People would also light bonfires to try to scare them away.Samhain was a three-day Celtic New Year festival that began on 31 October, so the timing and the links with ghosts gives historians a reason to suspect this may be where it came from.But the Celts did not leave written records, so it is difficult for anyone to be completely certain.In 1845, the Great Potato Famine forced around one million people living in Ireland to move to the US, taking traditions like Halloween with them.It was in America that the pumpkin became the vegetable that we all associate with the festival. In the UK, people used to carve turnips!According to Professor Candida Moss, who is an expert on early Christianity: "As a festival, Halloween has many faces.Nowadays,the Halloween is not only celebrated in former British colonies such as America and New Zealand,but also in some Asian countries like China and Japan.The mighty western culture made it become a global fiesta.
