亲爱的圣诞老人：
圣诞老人，你好!
我是一个来自中国的小学生。转眼间，一年一度的圣诞节到了，您过的还好吗?我虽不知您是怎么在一夜之间把礼物送到小朋友的手中，但您可不要忘了我呀!嘻嘻，今年我要的礼物可能多了些，您不会见怪吧! 第一件礼物是一个新书包。我现在的书包已经旧了，再说这个书包的空间也不大，现在呀，我已经有些东西放不下了。您送给我的书包最好是粉红色，因为这是我最喜欢的颜色了。
第二件呢，我想要一台新电脑。我们家的一台电脑坏了，又修不好，再说了，我家的另一台电脑，被我爸爸当书籍库了。一有想看的书，都去电脑上找。最后一件礼物呢，就是要一个漂亮的手表。我要的这个手表最好是独一无二的，它不仅可以让你知道现在的时间，还可以通话。只要对着手表说出对方的名字，就可以和对方联系。我期盼着您的到来!到这里，实现我的愿望。
敬祝圣诞快乐

圣诞老人“身世”揭密
身穿厚厚红白大袍的圣诞老公公，其实并不是是出生在冰冷的北极圈，而是地中海岸的登雷镇，所以他如果穿着这身打扮出现在老家，肯定是热得直呼受不了。
圣诞老人生于公元4世纪
据美联社报道，圣诞老人故事源自圣尼古拉这名宗教人物。他在公元4世纪担任土耳其登雷镇这个长时艳阳高照的小镇的主教，为人乐善好施;后来人们在他的生平事迹里加进了一些神话故事，最后就演变成大家今日熟悉的带着礼物、笑容满面的圣诞老公公。
圣诞老人第一份“圣诞”礼物是黄金
传说，镇上有1户贫困潦倒的人家，没钱替3个女儿置办嫁妆，对尼古拉知道后，在某个晚上把1袋黄金从窗户丢进了这户人家，隔天他又丢了1袋。
但第3天，窗户关了起来，圣尼古拉只爬上屋顶，从烟囱丢上金袋，结果正好落在女孩放在壁炉里烘干的袜子里面，最后就演变成在圣诞前夕挂袜子、等圣诞老人送上礼物的传统。
北欧奥丁神借来大白胡子
至于圣诞老人的大白胡子，则是来自北欧神话中统治世界的大神“奥丁”的形象;奥丁的座骑：8腿飞马，演变成圣诞老人的8只麋鹿。由烟囱进入屋里的行为，来自古代斯堪地纳维亚人的传统;备好饼干和牛奶等他来的传统，则衍生自中世纪的一则德国民间故事。
12世纪时，法国的修女开始在12月6日圣尼古拉的忌日，以他的名义赠予礼物。后来，圣尼古拉赠送礼物的行为，又和《圣经》记载，耶稣生后，东方三贤人带着礼物前来见的故事扯在一起，进而和对诞节扯上关系。
据威斯康辛神学家布朗表示，“慢慢地，圣尼古拉演变成孩子任何言行都难逃他的法眼的人，好孩子在圣诞节时就会得到圣诞老人赠予社物，坏小孩就会得到鞭子。”

The original Santa Claus, St. Nicholas, was born in the ancient southeastern Turkish town of Lycia early in the fourth century. His generosity was legend, and he was particularly fond of children. We know this primarily through Roman accounts of his patronage of youth, which eventually led to his becoming the patron saint of children. Throughout the Middle Ages, and well beyond, he was referred to by many names none of them Santa Claus.
Children today would not at all recognize the St. Nick who brought gifts to European children hundreds of years ago except perhaps for his cascading white beard. He made his rounds in full red-and-white bishop's robes, complete with twin peaked miter and crooked crozier. He was pulled by no fleet footed reindeer, but coaxed in indolent donkey. And he arrived not late on Christmas Eve, but on his Christian feast day, December 6. The gifts he left beside the hearth were usually small: fruit, nuts, hard candies, wood and clay figurines.
During the Protestant Reformation of the sixteenth century, St. Nicholas was banished from most European countries. Replacing him were more secular figures, who in general were not at center stage at that point in history..The Dutch kept the St. Nicholas tradition alive. As the protector of sailors, St. Nicholas graced the prow of the first Dutch ship that arrived in America. And the first church built in New York City was named after him. The Dutch brought with them to the New World two Christmas items that were quickly Americanized.
In sixteenth century Holland, children placed wooden shoes by the hearth the night of St. Nicholas's arrival. The shoes were filled with straw, a meal for the saint's gift laden donkey. In return, Nicholas would insert a small treat into each clog. In America, the shoe was replaced with the stocking, hung by the chimney.
The Dutch spelled St. Nicholas Saint Nikolass, which in the New World became Sinterklass. later changed to Santa Claus.
Much of modern day Santa Claus lore, including the reindeer drawn sleigh, originated in America. Dr. Clement Clarke Moore composed The Night Before Christmas in 1822, to read to his children on Christmas Eve. The poem might have remained privately in the Moore family if a friend had not mailed a copy of it (without authorial attribution) to a newspaper and became part of the Santa legend.
It was in America that Santa put on weight. The rosy-cheeked, roly-poly Santa is credited to the influential nineteenth-century cartoonist Thomas Nast. From 1863 until 1886, Nast created a series of Christmas drawings for Harper's Weekly. These drawings, executed over twenty years, exhibit a gradual evolution in Santa from the pudgy, diminutive, elf-like creature of Dr. Moore's immortal poem to the bearded, potbellied, life-size bell ringer familiar on street corners across America today. Nast's cartoons also showed the world how Santa spent his entire year constructing toys, checking on children's behavior, reading their requests for special gifts. His images were incorporated into the Santa lore.
Santa is known throughout the world in many different names, such as:
Saint Nikolaas (Sinter Klaas), from the Dutch Father Christmas, from the English Kris Kringle, from the Germans Befana, from the Italians Bobouschka, from the Russians (a grand motherly figure instead of a male)
