今天是本学期第4周的开始，刚到办公室来自美国的老外就拿来了一把三叶草和一张卡片（Top o' the mornin' And all day, too--May the luck o'the Irish Be Smilin' on you! Happy St. Patrick's Day）。说是一个源于爱尔兰的节日，到现在很多说英语的国家都庆祝这个节日。人们都要在身上点缀一些绿色的东西，否则会被小孩子门搞恶作剧。
在网上查了一下，圣帕特里克节为3月17日，以纪念爱尔兰守护神圣帕特里克。这一节日5世纪末期起源于爱尔兰，美国从1737年3月17日开始庆祝。公元432年，圣帕特里克受教皇派遣前往爱尔兰劝说爱尔兰人皈依基督教。他从威克洛上岸后，当地愤怒的异教徒企图用石头将他砸死。但圣帕特里克临危不惧，当即摘下一棵三叶苜蓿，形象地阐明了圣父、圣子、圣灵三位一体的教义。他雄辩的演说使爱尔兰人深受感动，接受了圣帕特里克主施的隆重洗礼。公元493年3月17日，圣帕特里克逝世，爱尔兰人为了纪念他，将这一天定为圣帕特里克节。
1737年，一些爱尔兰绅士和商人们在美国马萨诸塞州波士顿聚会纪念圣帕特里克，并成立了爱尔兰慈善社团。1780年和1784年，费城和纽约先后成立了圣帕特里克友谊之子等团体，从此美国每年都庆祝这个节日。美国的圣帕特里克节这一天，人们通常要举行游行、教堂礼拜和聚餐等活动。美国的爱尔兰人喜欢佩带三叶苜蓿，用爱尔兰的国旗颜色——绿黄两色装饰房间，身穿绿色衣服，并向宾客赠送三叶苜蓿饰物等。

The First Parade
St. Patrick's Day is celebrated on March 17, his religious feast day and the anniversary of his death in the fifth century. The Irish have observed this day as a religious holiday for thousands of years.
On St. Patrick's Day, which falls during the Christian season of Lent, Irish families would traditionally attend church in the morning and celebrate in the afternoon. Lenten prohibitions against the consumption of meat were waived and people would dance, drink, and feast—on the traditional meal of Irish bacon and cabbage.
The first St. Patrick's Day parade took place not in Ireland, but in the United States. Irish soldiers serving in the English military marched through New York City on March 17, 1762. Along with their music, the parade helped the soldiers to reconnect with their Irish roots, as well as fellow Irishmen serving in the English army.
Over the next thirty-five years, Irish patriotism among American immigrants flourished, prompting the rise of so-called "Irish Aid" societies, like the Friendly Sons of Saint Patrick and the Hibernian Society. Each group would hold annual parades featuring bagpipes (which actually first became popular in the Scottish and British armies) and drums.

No Irish Need Apply
Up until the mid-nineteenth century, most Irish immigrants in America were members of the Protestant middle class. When the Great Potato Famine hit Ireland in 1845, close to a million poor, uneducated, Catholic Irish began to pour into America to escape starvation. Despised for their religious beliefs and funny accents by the American Protestant majority, the immigrants had trouble finding even menial jobs. When Irish Americans in the country's cities took to the streets on St. Patrick's Day to celebrate their heritage, newspapers portrayed them in cartoons as drunk, violent monkeys.
However, the Irish soon began to realize that their great numbers endowed them with a political power that had yet to be exploited. They started to organize, and their voting block, known as the "green machine," became an important swing vote for political hopefuls. Suddenly, annual St. Patrick's Day parades became a show of strength for Irish Americans, as well as a must-attend event for a slew of political candidates. In 1948, President Truman attended New York City 's St. Patrick's Day parade, a proud moment for the many Irish whose ancestors had to fight stereotypes and racial prejudice to find acceptance in America.

Wearing of the Green Goes Global
Today, St. Patrick's Day is celebrated by people of all backgrounds in the United States, Canada, and Australia. Although North America is home to the largest productions, St. Patrick's Day has been celebrated in other locations far from Ireland, including Japan, Singapore, and Russia.
In modern-day Ireland, St. Patrick's Day has traditionally been a religious occasion. In fact, up until the 1970s, Irish laws mandated that pubs be closed on March 17. Beginning in 1995, however, the Irish government began a national campaign to use St. Patrick's Day as an opportunity to drive tourism and showcase Ireland to the rest of the world. Last year, close to one million people took part in Ireland 's St. Patrick's Festival in Dublin, a multi-day celebration featuring parades, concerts, outdoor theater productions, and fireworks shows.
