How Americans Celebrate Christmas
Christmas is America' s most popular holiday. Some people will attend church and observe Christmas as the birthday of Christ. For others, Christmas is just a day of fun and celebration, a time for family and friends to gather together, exchange gifts and enjoy a huge holiday dinner. Christmas Day will need weeks of preparations. Since the last days of November American homes and stores have been decorated with Christmas trees and bright lights. Schools and churches have been presenting special holiday concerts. People have been going to parties, finding gifts and preparing special Christmas food. For a large number of Americans, Christmas is surrounded by more traditions than any other holiday. Yet, many of these traditions are not really very old ones in the United States. In fact, the nation's first settlers would have. been very surprised to see how Americans celebrate Christmas today.
People in other parts of the world, of course, have been celebrating Christmas for many centuries. In fact, December was a winter holiday season in northern and southern Europe even before the birth of Christ. And the ancient Romans celebrated the New Year on December twenty-fifth. Some experts believe that is why the Roman Catholic Church set the birth of Christ on that day. Christians borrowed other Christmas traditions from ancient times. In the years before Christ, for example, people honored the evergreen tree as a sign of life after death. For Christians, it became a sign of Christ's birth. By the 16th century Roman Catholics in Europe were celebrating Christmas with lively parties filled with eating and drinking. Many of the first Europe an settlers in America, however, disapproved of such customs. They believed people should honor God in simpler, quieter ways, so Christmas became a day just like any other day for most people in America's northern colonies.
In America' s southern colonies, however, the Church of England became the established religion. Its traditions were closer to those of Roman Catholic Church. So it became common for people on large farms in the south to celebrate Christmas with huge dinners and dancing. And in many parts of America, smaller groups of settlers from other western European countries observed Christmas with their own national customs. After 1,800, all these people began to mix together more and they began to borrow Christmas traditions from each other. Settlers from Ger many, for example, observed Christmas by cutting live evergreen trees and covering them with candies and fruit. By the middle of the 19th century, people all over America were putting up evergreen trees at Christmas. Dutch settlers in New York were most responsible for creating another popular American tradition--Santa Claus.
The story of Santa Claus began hundreds of years earlier. During the fourth century, a Roman Catholic Church official called Nicholas of Myra became famous for his many good actions. Nicholas was made a saint (圣人) after his death and it became common in northern Europe to hold a celebration on December 6th, the day Nicholas died. All kinds of stories were told about Saint Nicholas and the Dutch brought one of these stories with them to America. They believed that each year the saint rode a white horse from home to home. He gave presents to children who had been good, and coal or straw to children who had been bad. Other Americans who lived nearby greatly enjoyed the Dutch celebrations. They decided to make Saint Nicholas part of their own celebration of Christmas. But he got a new name Santa Claus. It was taken from the Dutch words for Saint Nicholas, Santa Claus. The Dutch imagined Saint Nicholas to be a serious, even frightening person, who would punish as well as give gifts. But in 1822, an American named Clement C. Moore wrote a Christmas poem for his children. The poem, called A Visit From St. Nicholas, created a

问答题

I am always a little puzzled when I hear people complain about the difficulties of finding a good job. Young people in their 20s express dissatisfaction that all the good jobs have been taken by those in their 40s. People in their 40s, trapped in the middle groups of the workforce, complain about waiting for their elders to. make room for them at the top. Older employees worry about being forced out of the job market prematurely by younger people willing to work at entry-level wages. It is not a pretty picture.
But I do not buy it. In my view, differences between generations are not a problem but an opportunity—if you remember to apply some basic principles of self-marketing. Most of us learned from Marketing 101 textbooks that there are four phases in the life cycle of a product or brand. The names may differ, but essentially the four phases are Introduction, Growth, Maturity and Decline. As a manager of high-profile athletes for more than 30 years, I know that these four phases certainly apply to the career and marketability of an athlete.
An athlete's introduction or start-up phase is when he or she starts competing, does well and captures the attention of people in the sport. Introduction turns into the growth phase when the athlete goes from being a promising performer to an established star. That's when everybody wants a piece of the athlete's time and he must stay focused on his primary talent and not get distracted by side issues.
For an athlete, the toughest thing about the mature phase may simply be recognizing that he or she is in it. If you're marketing a bar of soap it is easy to tell if the product is mature. It is there in the stagnant or shrinking sales figures. It is different with athletes. Not only do they think the growth phase will never end, but they often deny that there is any decrease in their athletic skills or marketability, no matter what the numbers say.
The decline phase for an athlete may sound harsh, but it doesn't have to be if he or she thinks of it as a reflective phase. In this phase an athlete can have tremendous future as a legendary figure who functions as an ambassador for his or her sport. If you substitute 'employee' for 'athlete' in these examples, these four phases apply to any individual's career.
I genuinely believe that whenever people face a career crisis, a big reason is because they are 'out of phase.' I have always been a tremendous advocate of recruiting older workers. With the massive downsizing of corporate America, there are tens of thousands of talented men and women over the age of 50 who feel shut out of the work-place. To me, these people are a gold mine—not because they are available but rather because they possess the qualities that employees in the introduction and growth phases lack, namely wisdom and experience. And since many of them received generous early-retirement packages, money is not their sole motivation. In other words, they are affordable.
If I were marketing myself in the mature phase, I'd focus on these qualities. Wisdom, experience and affordability make up a potent package. But you cannot do that unless you first recognize and fully appreciate the phase you are in.
What can be concluded from the passage?
A.Most young people cannot find a job if they don't study the four phase theory.
B.Young people with good jobs have studied the four phase theory.
C.Job seekers should fully understand the phase they are in.
D.Older employees will be forced out of job market by the young.
