Friday-the Thirteenth has long been considered extremely unlucky because it has some bad associations which came from mythology,tale of the Bible,and the customs and habits. According to the Bible,the Lord God created the first man,Adam.Then he took a rib from Adam's body and out of it created the first woman, Eve. It was said that Adam was created on a Friday and it was on Friday that Adam and Eve ate the forbidden fruit,and on a Friday they died. 　

　Friday was also the common day in England for executing criminals , for which it was sometimes known as Hanging Day.

　From the old Norse myth people got the idea that 13 people sitting at a table to have a dinner was unlucky. And this superstition was confirmed by the last supper of Christ and his disciples. Bible tells us that Christ sat down with his 12 disciples, which made up the number 13, at the last supper when Judas, one of the 12 disciples , sold his master for thirty pieces of silver. Christ was killed by nailing on the cross the following day on a Friday.

星期五和13歷來被認為是非常不吉利的日子，這是從神話、圣經(jīng)故事、風俗習慣產(chǎn)生的一些不好的聯(lián)想而來的。據(jù)圣經(jīng)上講，上帝創(chuàng)造了第一個男人--亞當。然后，上帝從亞當身上取下一根肋骨又造了一個女人-夏娃。據(jù)說，亞當是在星期五被造出來的，他和夏娃吃禁果也在星期五，他倆死的日子也是星期五。

　　英國從前常常在星期五處死罪犯、因此星期五有時也叫"絞刑日"。

　　從挪威神話中，人們產(chǎn)生一種想法：13個人坐在一起聚餐是不吉利的。這種迷信 被耶穌和其12個門徒的最后的晚餐加以證實。圣經(jīng)上說，在最后的晚餐上，耶穌 和他的12個門徒坐在一起，正好是13人。他的門徒之一-猶大，為了三十個銀幣而出賣了自己的老師。第二天，耶穌便被釘死在十字架上，這天碰巧是星期五。
