单选题{{B}}Passage Five{{/B}} In every language there are two great classes of words which, taken together, consist of the whole vocabulary. First, there are those words with which we become acquainted in daily conversation, which we learn, that is to say, from the members of our own family and from our familiar associates, and which we should know and use even if we could not read or write. They concern the common things of life, and are the goods in trade of all those who speak the language. Such words may be called "popular", since they belong to the whole people; and are not the exclusive possession of a limited class. On the other hand, our language includes a large number of words which are comparatively seldom used in ordinary conversation. Their meanings are known to every educated person, but there is little occasion to use them at home or in the market-place. Our first acquaintance with them comes not from our mother's lips or from the talk of our school-mates, but from books that we read, lectures that we bear, or the more formal conversation of highly educated speakers who are discussing some particular topic in a style raised above the habitual level of everyday life. Such words are called "learned". And the distinction between them and "popular" words is of great importance to a right understanding of the language.

单选题Questions 11-15 are based on the following passage: All the people who went to the new supermarket had one great hope: to be the lucky customer who did not have to pay for his shopping. For this was what the notice just inside the entrance promised. It said, "Remember, once a week, one of our customers gets free goods. This may be your lucky day!" For several weeks Mrs. White hoped, like many of her friends, to be the lucky customer. Unlike her friends, however, she never lost heart. Her kitchen was full of things which she did not really need. Her husband tried again and again to persuade her to give it up, but she just wouldn't listen. She dreamed of the day when the manager of the supermarket would come up to say, "Madam, this is your lucky day. Everything in your basket today is free." One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy some tea. She rushed back to the supermarket, got the tea and went to the desk to pay for it. As she was walking, she saw the manager of the supermarket coming up. "Madam," he said warmly, holding out his hand, "I want to congratulate you! You are our lucky customer today. Everything you've got in your basket is free./

单选题"It was the beginning of a revolution in America and the world, a revolution that some have yet to acknowledge and many have yet to appreciate," says Harold Skramstad, president of the Henry Ford Museum in Dearborn, Michigan. 1776? No indeed. 1896, when Frank Duryea finally perfected the Duryea Motor Wagon. At its first airing, the contraption rolled less than 100 metres before the transmission froze up. But by the end of 1896 Duryea had sold 13 of them, thus giving birth to the American motor industry. That industry (whose roots, outside America, are usually attributed to tinkerings by Messrs Daimler and Benz in Germany) is being celebrated hugely over the coming months, culminating with a Great American Cruise in Detroit in June. "Our goal is to attract the greatest collection of antique and classic cars this nation has ever seen in one place at one time," says Mr. Skramstad modestly. Americans may indeed blame the car for almost everything that has happened to their country, and themselves, since 1896. The car has determined. The way they live. From cradle to grave, the car marks every rite of American passage. Home by car from the maternity ward; first driving licence (usually at the age of 16); first (backseat) sexual experience; first car of one's own (and the make of car is a prime determinant of social status, symbolic of everything a person is or does). In Las Vegas, and elsewhere, Americans can get married at drive-in chapels. They then buy, or lust after, a house with garages big enough for not one but two or three cars. This allocates more space to cars than to children. And when the time comes, they may lie in state at a drive-through funeral home, where you can pay your respects without pulling over. The way they shop. Main Street has been replaced by the strip mall and the shopping mall, concentrating consumer goods in an auto-friendly space. A large part of each shopping trip must now be spent, bags under chin, searching for the place where the car was left. (And another point: bags have annoyingly lost their carrying handles since shoppers ceased to be pedestrian) Since car-friendly living and shopping became the role, most built-up parts of America now look like every other part. There is simply no difference between a Burger Inn in California and one on the outskirts of Boston. The way they eat. A significant proportion of Americans' weekly meals are now consumed inside cars, sometimes while parked outside the (drive-by) eatery concerned, sometimes en route, which leads to painful spillages in laps, leading to overburdening of the legal system. Dozens of laws have been written to deal with car cases, ranging from traffic disputes to product liability. Drive-by shootings require a car, as do most getaways. The car is a great crime accessory; and it als0 causes the deaths of nearly 40,000 Americans every year. Personal finances. Before the age of the car, few people went into debt; no need to borrow money to buy a home. Now Americans tie themselves up with extended installment loans, and this in turn has spawned a whole financial industry. The wealth of the nation. By 1908, an estimated 485 different manufacturers were building cars in the United States. Employment grew nearly 100-fold in the industry during the first decade of the 20th century. When Henry Ford, in a stroke of genius, automated his production line he required a rush of new, unskilled labour, which he enticed by offering an unheard-of $ 5 a day in wages. Henceforth, workers could actually afford to buy what they built. And Americans never looked back. Today, the Big Three car manufacturers (Food, GM and Chrysler) generate more than $200 billion a year in business inside the United States. Directly and indirectly, the industry employs roughly one in seven workers. Every car job is reckoned to add $100,000 in goods and services to the economy, twice the national average. People occasionally suppose that the car is under attack as it enters its second century. Environmental regulators and transport planners (with their talk of car pools and subways) tend to give this impression. There are signs that personal computers may be replacing the sports car as the chief passion, and expense, of young men. But, in the end, nothing beats the idea of individual mobility. In a society that values freedom above all, the obvious way to celebrate a centenary is just to keep driving.
