单选题{{B}}Passage 2{{/B}} "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 Main Street has been replaced by the strip mall and the shopping mall, concentrating consumer goods in an auto-friendly space.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.

单选题It is possible for students to obtain advanced degrees in English while knowing little or nothing about traditional scholarly methods. The consequences of this neglect of traditional scholarship are particularly unfortunate for the study of women writers. If the canon—the list of authors whose works are most widely taught—is ever to include more women, scholars who do not know how to read early manuscripts, locate rare books, establish a sequence of editions, and so on are lacking in crucial tools for revising the canon. To address such concerns, an experimental, version of the traditional scholarly methods course was designed to raise students' consciousness about the usefulness of traditional learning for any modern critic or theorist. To minimize the artificial aspects of the conventional course, the usual procedure of assigning a large number of small problems drawn from the entire range of historical periods was abandoned, though this procedure has the obvious advantage of at least superficially familiarizing students with a wide range of reference sources. Instead students were engaged in a collective effort to do original work on a neglected eighteenth-century writer, Elizabeth Griffith, to give them an authentic experience of literary scholarship and to inspire them to take responsibility for the quality of their own work. Griffith's work presented a number of advantages for this particular pedagogical purpose. First, the body of extant scholarship on Griffith was so tiny that it could all be read in a day, thus students spent little time and effort mastering the literature and, had a clear field for their own discoveries. Griffith's play The Platonic Wife exists in three versions, enough to provide illustrations of editorial issues but not too many for beginning students to manage. In addition, because Griffith was successful in the eighteenth century, as her continued productivity and favorable reviews demonstrate, her exclusion from the canon and virtual disappearance from literary history also helped raise issues concerning the current canon. The range of Griffith's work meant that each student could become the world's leading authority on a particular Griffith text. For example, a student studying Griffith's Wife in the Right obtained a first edition of the play and studied it for some weeks. This student was suitably shocked and outraged to find its title transformed into A Wife in the Night in Watt's Bibliotheca Britannica. Such experiences, inevitable and common in working on a writer to whom so little attention has been paid, serve to vaccinate the student I hope for a lifetime against credulous use of reference sources.

单选题As women demonstrate a growing appetite for consumer tech products, retailers and manufacturers are still only beginning to cater to this potentially huge reservoir of customers. High-tech businesses and electronics retailers are changing store designs, increasing their marketing toward women, focusing on gadget accessories and boosting advertising in women's magazines--all in a pitch to get women to walk the aisles and walk out with cell phones, MP3 players and plasma televisions. To draw women in, stores have been turning down the music, changing the color schemes and adding staff trained to meet women's needs. Radio Shack has gussied up its gray and black decor with bright purple, orange and green at its newer stores. Aisles have been widened and the product arrangements redone to make the place look less like a cluttered electronics hardware store. The company also has put more women on the sales floor. "The store doesn't feel like a men's club anymore," said Charles Hodges, a spokesman for Radio Shack. "Now women can walk in and be helped by women just as knowledgeable as guys." Most technology manufacturers have few women among their top executives, and that translates into the kinds of products on the shelves and the way they are marketed, according to Quinlan, author of "Just Ask a Woman-cracking the Code of What Women Want and How They Buy". Few devices-iPods and Palm handheld computers are among the exceptions--tap into a woman's sense of style, she said. "Design is key-attractive, holdable, showable design." she said. Women often are swayed to buy a product for reasons far different than those that drive men. They will choose a gadget not because they want to be a pioneer but be-cause they and their friends have discovered the usefulness of the thing. "Where men like to be the only one with a product, women like to bring more of her friends into their find--they want to share the good news of what's working for them," Quinlan said. But friends are only one of the ways that women are discovering what's important to them when it comes to tech. There's also a growing number of outside influences--product-specific or trend articles in magazines that target women of all ages, for example. Recently, Radio Shack worked with Seventeen magazines--known for its fashion, beauty and relationship features for young women--on a story about MP3 players.
