Passage 1People over the age of 65 in the U.S.A are called senior citizens. Life for these people is different from that for younger Americans. Most senior citizens retire, or no longer work full time. Also it is unusual for people of this age to live with their children and grandchildren. Grandparents tend to live in their own houses or apartments away from their families.For many senior citizens, the years after 65 are not enjoyable. They feel unproductive when they no longer work. Their lives lose meaning. In addition, they may feel lonely being away from their families and the contacts they had in their work. Moreover, they become more concerned with their health as they grow older. If they live in big cities, they often worry about their safety.Other senior citizens enjoy their lives. They feel free to do things they were not able to do when they were working and raising families. They now have time to enjoy hobbies and sports and travel. They associate with their fellow senior citizens who have common interests and equal free time. Many senior citizens move to retirement communities located in warm climates. Some senior citizens continue to work beyond retirement age. Many find new careers and professional opportunities after they retire.The number of senior citizens in the U.S.A is increasing rapidly because people are living longer than before. The average life span for Americans in now more than 74 years. Because of their larger numbers and more active life styles, senior citizens are gaining social influence in the country both politically and economically. Their concerns are receiving a wider audience than ever before. The time may come when all Americans will look forward to becoming senior citizens.31.Many senior citizen________ .

Passage 2The digital revolution, as exemplified by the Internet and electronic commerce, has shaken marketing practices to their core. In a recent paper, Wharton’s Jerry Wind, director of the SEI Center for Advanced Studies in Management, and co-author Vijay Mahajan, a marketing professor at the College of Business Administration of the University of Texas at Austin, examine the impact of digital marketing on concepts like pricing, when customers can propose their own prices (priceline.com), or buyers and sellers can haggle independently in auctions (eBay.com).The paper provides an overview of some of the emerging realties and new rules of marketing in a digital world, and outlines what the new discipline of marketing may look like in the early part of the new century.To begin with, say the authors, the rapid-fire growth of the Internet is helping to drive changes. “It is not just our computers that are being reprogrammed; it is customers themselves,” says Wind. “These emerging cyber consumers are like an alien race that have landed in the midst of our markets. They have different expectations and different relationships with companies from which they purchase products and services.”For one thing, cyber consumers expect to be able to customize everything — from the products and services they buy and the information they seek, to the price they are willing to pay. And with digital technology opening new channels for gaining information, they are more knowledgeable and demanding than previous consumers.Digital customers can also sort products based on any desired attribute, price, nutritional value, or functionality, and they can easily obtain third-party endorsements and evaluations, tapping the experience of other users. “Companies that cannot meet their demands and expectations will be at a loss,” says Wind.34.The passage was most likely to be taken from________.

Passage 3In ancient times wealth was measured and exchanged tangibly, in things that could be touched: foods, tools, and precious metals and stones. Then the barter system (以货易货贸易制度) was replaced by coins, which still had real value since they were pieces of rare metal. Coins were followed by fiat money (不兑换的纸币), paper notes that have value only because everyone agrees to accept them.Today electronic monetary systems are gradually being introduced that will transform money into even less tangible forms, reducing it to arrays of “bits and bytes,” or units of computerized information, whizzing (发嗖嗖声) between machines at the speed of light. Already, electronic fund transfer allows money to be instantly sent and received by different banks, companies, and countries through computers and telecommunications devices.38.According to the passage, which of the following was the earliest kind of exchange of wealth?
