单选题Web browsers! Interactive software! There"s a lot of new technology talk going on in public relations these days, and it"s coming from a variety of sources, clients, fearful that they are missing out on some mysterious "next wave", demand some kind of whiz-bang (尖端) demonstration of technology from agencies. Industry publications continuously tout the latest and greatest electronic innovations. College kids enter the marketplace armed with computer literacy completely alien to many veteran practitioners. And in some cases, members of the media demand that information be packaged to accommodate their particular technological preferences. Is technology now the tail wagging dog? The answer, unequivocally, is no. Technology remains what it has always been, a tool used by professionals to help them do their jobs. All of this millennium talk has produced an unnecessary level of anxiety about the necessity of technological innovation—the idea that you are light-years behind unless you are light—years ahead. Relax! The foundations of good public relations remain the same: anticipating and meeting the needs of clients and the media, and providing informed and useful counsel. Solid research, strong writing skills, creativity, and an appreciation for the values of the media are the backbone of the profession, regardless of how information is packaged. Even if the speed of information transmission is increasing, high tech isn"t for everyone. All clients don"t need individual web pages and summaries of chat room activity. When considering applications of new technologies, consider the audiences for your client. Are they comfortable with technology? Do they have access to the distribution systems you are considering? Do they have the skills and knowledge to use these systems? Do they navigate the web, use CD-ROM, or even own a VCR? Consider the image of the company itself. The delivery system is part of the message and contributes to the overall image, so the practitioner should consider how that system affects the client, the product, and the audiences. Yes, a web page can be a cost-efficient communication tool when you consider the minimal media cost. But once it"s up and running, you"ve got to keep it fresh, and that means a continual allocation of time and specialized resources. In the hyper-speed model of communications, nothing is older than information that is both outdated and online. And to information consumers, your web page will cease to be a source if it isn"t kept current. In the last presidential election, more than one candidate had problems with their personal web pages because webmasters were not kept up to date on changes in campaign strategy and messages. The gap between what the candidate was saying and what the web page was showing became a story in itself. If you"re going to have a presence on the Internet, you have to budget for regular maintenance. Otherwise, you are putting a sign up that says "too cheap to be relevant".

单选题In some society it is the custom for parents to arrange the marriages of their children. The father and mother of the bride will meet with the father and mother of the groom, and if both families are pleased with each other, an agreement will be made. Often the brides and grooms will not be asked for their opinion in this matter, and sometimes they do not even meet each other until the day of the wedding. In some countries, men advertise for mail-order brides in the heal paper. Most Americans find the idea of arranged marriages difficult to understand or accept. They believe that two people should marry for love, after a period of dating or courtship. During that period, the prospective marriage partners are supposed to learn enough about each other to decide whether or not they will be able to build a successful marriage. Today in America, it is common for people to live together as a way of preparing for marriage. The idea of an arranged marriage seems very old fashioned indeed. But aren't all marriages arranged in one way or another? In the United States marriages are seldom formally arranged, but quite a lot of informal arranging goes on before two people become husband and wife. People who get married are introduced to each other by friends. These friends have already decided that the two people are right for each other and arrange for them to meet. In the United States this kind of arrangement is very common. Because friends have such great influence, their approval of a dating or mating partner is very important. Families also exert open and subtle pressures on their children to influence their choices of marriage partners. Parents often arrange dates for their own children. One parent often tells a friend a bout her beautiful daughter or handsome son. Also, parents can meet the perfect marriage prospect for their son or daughter through business relationships. Since parents often assist their children financially, they feel that they have the right to help the bride and groom select where they will live, what type of furniture they will purchase, and what their life-style will be like. To a larger extent, social class determines the choice of a marriage partner in the United States. Marriages are usually arranged between people of similar religious, ethnic, and financial back grounds. Despite what we see in the movies, the son of a bank president rarely marries or even meets a miner's daughter. Americans may not accept or understand arranged marriages, but marriages in the United States are arranged nevertheless.

单选题Today is the anniversary of that afternoon in April a year ago that I first saw the strange and appealing doll in the window of Abe Sheftel"s toy shop on Third Avenue near Fifteenth Street, just around the comer from my office, where the plate on the door reads: Dr. Samuel Amory. I remember just how it was that day: the first hint of spring floated across the East River, mixing with the soft-coal smoke from the factories and the street smells of the poor neighborhood. As I turned the comer on my way to work and came to Sheftel"s, I was made once more aware of the poor collection of toys in the dusty window, and I remembered the approaching birthday of a small niece of mine in Cleveland, to whom I was in the habit of sending modest gifts. Therefore, I stopped and examined the window to see if there might be anything suitable, and looked at the confusing collection of unappealing objects—a red toy fire engine, some lead soldiers, cheap baseballs, bottles of ink, pens, yellowed envelopes, and advertisements for soft drinks. And thus it was that my eyes eventually came to rest upon the doll stored away in one corner, a doll with the strangest, most charming expression on her face. I could not wholly make her out, due to the shadows and the film of dust through which I was looking, but I was aware that a tremendous impression had been made upon me as though I had run into a person, as one does sometimes with a stranger, with whose personality one is deeply impressed.

单选题During the cold war the world was divided into the First, Second and Third Worlds. Those divisions are no longer relevant. It is far more meaningful now to group countries not in terms of their political or economic systems or in terms of their level of economic development but rather in terms of their culture and civilization. What do we mean when we talk of a civilization? A civilization is a cultural entity. Villages, regions, ethnic groups, nationalities, religious groups, all have distinct cultures at different levels of cultural heterogeneity. The culture of a village in southern Italy may be different from that of a village in northern Italy, but both will share in a common Italian culture that distinguishes them from German villages. European communities, in turn, will share cultural features that distinguish them from Arab or Chinese communities. Arabs, Chinese and Westerners, however, are not part of any broader cultural entity. They constitutes civilization. A civilization is thus the highest cultural grouping of people and the broadest level of cultural identity people have short of that which distinguishes humans from other species. It is defined both by common objective elements, such as language, history, religion, customs, institutions, and by the subjective self-identification of people. People have levels of identity: a resident of Rome may define himself with varying degrees of intensity as a Roman, an Italian, a Catholic, a European, or a Westerner. The civilization to which he belongs is the broadest level of identification with which he intensely identifies. People can and do redefine their identities and, as a result, the composition and boundaries of civilizations change. Civilizations may involve a large number of people, as with China ("a civilization pretending to be a state, as Lucian Pye put it"), or a very small number of people, such as the Anglophone Caribbean. A civilization may include several nation states, as is the case with Western, Latin American and Arab civilizations, or only one, as is the case with Japanese civilization. Civilizations obviously blend and overlap, and may include subcivilizations. Western civilization has two major variants, European and North American, and Islam has its Arab, Turkic and Malay subdivisions. Civilizations are nonetheless meaningful entities, and while the lines between them are seldom sharp, they are real. Civilizations are dynamic; they rise and fall; they divide and merge. And, as any student of history knows, civilizations disappear and are buried in the sands of time. Westerners tend to think of nation states as the principle actors in global affairs. They have been that, however, for only a few centuries. The broader reaches of human history have been the history of civilizations. In A Study of History, Arnold Toynbee identified 21 major civilizations; only six of them exist in the contemporary world. Civilization identity will be increasingly important in the future, and the world will be shaped in large measure by the interactions among seven or eight major civilizations. These include Western, Confucian, Japanese, Islamic, Hindu, Slavic-Orthodox, Latin American and possibly African civilization. The most important conflicts of the future will occur along the cultural fault lines separating these civilizations from one another.
