单选题{{B}}Passage 49{{/B}} {{U}}Although English is not as old as Chinese, it is spoken by many people around the world every day.{{/U}} English speakers are always creating new words, and we are often able to know where most words come from. Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered, "We come from Hamburg." One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburg ate. Then he put them between two pieces of bread and started selling them. Such bread came to be called "hamburgers". Today, "hamburgers" are sold in many countries around the world. Whether this story is true or not, it certainly is very interesting. Knowing why any word has a certain meaning is interesting, too. The explanation, for most English words, can be found in any large English dictionary.

单选题Economics is the study of how societies with limited resources decide what to produce, how to produce and for whom to produce. What, how, and for whom to produce are problems all over the world because human wants are practically unlimited, but all societies have only limited quantities of resources that can be used to produce goods or services. A knowledge of basic economics is important for understanding both the problems and opportunities that will face the world economy in the 21st century. As a student of economics, one will have the chance to discover how commerce, government policies, and day-to-day decisions made by consumers affect his living standards. The study of economics can help him understand the influence of such events as the move to free markets in Poland and Russia, or of ups and downs in interest rate and the foreign exchange rate. Economics is influenced by developments in the many different areas of business, politics, science, nature, religion and history. And whether or not one is aware of it, economics is an important part of his life. From a practical point of view, one's study of economics will help improve his decision-making skills. He learns a logical way to compare different courses of action. As he studies the concept of opportunity cost, for instance, he will discover that every choice he makes has both a benefit and a cost. Suppose someone decides to get a part time job so he can earn enough money to buy a car. He will have the benefit of owning the car, but he will pay a cost in terms of the leisure hours he gives up for working so as to pay for the car and keep it in good condition. After weighing his choice in cost benefit terms, he may decide he does not need a car any more.

单选题Almost every family buys at least one copy of a newspaper every day. Some people subscribe(订阅) to as many as two or three newspapers. But why do people read newspapers? Five hundred years ago, news of important happenings - battles lost and won, kings or rulers overthrown(推翻)or killed took months and even years to travel from one country to another. The news passed by word of mouth and was never accurate. Today we can read in our newspapers of important events that occur in far away countries on the some day they happen. Apart from supplying news from all over the world, newspapers give us a lot of other useful information. There are weather reports, radio, television and film guides, book reviews, stories and, of course, advertisements. (76) The bigger ones are put in by large companies to bring attention to their products. They pay the newspapers thousands of dollars for the advertising space, but it is worth the money, for news of their products goes into almost every home in the country. For those who produce newspapers, advertisements are also very important. Money earned from advertisements makes it possible for them to sell their newspapers at a low price and still make a profit. (77) Newspapers often have information on gardening, cooking and fashion, as well as a small but very popular section on jokes and cartoons(漫画).

单选题"High tech" and "state of the art" are two expressions that describe very modern technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system of device that uses the newest ideas or discoveries of sci-ence and engineering. What is high tech? A computer is high tech. So is a communications satellite. A modern manufacturing (生产) system is surely high tech. High tech became a popular expression in the United States during the early 1980's. (17) Because of improvements in technology, people could buy many new kinds of products in American stores, such as home computers, microwave (微波) ovens, etc. "State of the art" is something that is as modern as possible. It is a product that is based on the very latest methods and technology. Something that is "state of the art" is the newest possible design or product of a business or industry. A state of the art television set, for example, uses the most modern electronic design and parts. It is the best that one can buy. "State of the art" is not a new expression. Engineers have used it for years, to describe the best and most modern way of doing something. Millions of Americans began to use the expression in the late 1970's. The reason was the computer revolution. Every computer company claimed that its computers were "state of the art". Computer technology changed so fast that a state of the art computer today might be old tomorrow. The expression "state of the art" became common and popular as computers themselves. Now all kinds of products are said to be "state of the art".
