    Saint Patrick's Day is a major holiday in Ireland, but the rest of the world has influenced its celebration as much as the Irish{#blank#}1{#/blank#} (they). Most Americans think of Saint Patrick's Day as a big party{#blank#}2{#/blank#}(center) around drinking alcohol. But its {#blank#}3{#/blank#} (origin) in Ireland were religious, says Mike Cronin, a professor of Irish history with Boston College of Massachusetts.

    Saint Patrick lived in Ireland more than 2,000 years ago. He is{#blank#}4{#/blank#} (wide) considered to have established Christianity in the country. The Church decided to honor him with a holy day. March 17, the date of his death{#blank#}5{#/blank#} (choose) in the 17lh century.

    St. Patrick is believed{#blank#}6{#/blank#}(serve) in Ireland as a Catholic Bishop (主教). The average Irish person honored March 17 quietly{#blank#}7{#/blank#}(attend) church services was the main activity. In fact, most businesses that served alcohol would close in honor {#blank#}8{#/blank#} the day. In the early 1900s, Ireland's government made St. Patrick's Day{#blank#}9{#/blank#} official holiday. By the 1960s, towns across Ireland started celebrating the holiday with parades and music.

    In Ireland today, St. Patrick's Day is a four-day public celebration {#blank#}10{#/blank#} includes parades, music, food, and games.

    Friends play an important part in our {#blank#}1{#/blank#} (life). Though we may take friendship for granted, we often don't clearly understand {#blank#}2{#/blank#} we make friends. While we get on {#blank#}3{#/blank#}(good) with many people, we are usually friends with only a few—for example, per student usually {#blank#}4{#/blank#} (have) about 6 friends. In all the cases of friendly relationships, two people like one another and enjoy {#blank#}5{#/blank#} (be) together. {#blank#}6{#/blank#}fact, as we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these things are not of great {#blank#}7{#/blank#} (important), {#blank#}8{#/blank#} is more difficult to get on with people when there is an obvious difference in age and background. Compared with marriage, there are no friendship ceremonies to {#blank#}9{#/blank#} (strong) the connection between two people. But the mutual（彼此的）understanding that results from common experiences and emotions does seem to create a powerful bond, {#blank#}10{#/blank#} can overcome difference in background, and break down barriers（障碍）of age, class and race.
